Board Update: Spring Forward

David DeRemer, PharmD BCOP FCCP FHOPA
HOPA President (2020–2021)
Clinical Associate Professor, University of Florida College of Pharmacy
Assistant Director, Experimental Therapeutics, University of Florida Health Cancer Center
Gainesville, FL

John F. Kennedy profoundly wrote, “Change is the law of life, and those who look only to the past and present are certain to miss the future.” As we look back over the past year, COVID-19 has signifi­cantly impacted our daily lives and has led to substantial changes that may persist well into our futures.

In this issue of HOPA News, member contributors share their experiences and insight on how COVID-19 has disrupted pharmacy practices. Among other changes, telehealth services emerged in the management of oral chemotherapy, as discussed in the cover story.

The need to adapt has led to substantial change for many within our organization. Is the practice transformation toward telehealth cemented in our professional futures? What other changes may persist long after the pandemic? For additional insight, I encourage you to attend our Annual Conference 2021 (AC21) where there are Clinical Pearls dedicated to this topic.

Diversity, Equity, and Inclusion (DEI)
As a society, the narrative has shifted from diversity and inclusion toward equity; as an organization, we are committed to adapting to these changes. HOPA continues to be engaged with other pharmacy organizations within Joint Commission of Pharmacy Practitioners (JCPP) to prioritize strategies to combat racial injustice.

In January, all HOPA Board members and staff virtually attended a DEI retreat led by Priya Jindal from Nextpat. I know I speak for everyone when I say this experience was valuable for us as individuals and collectively as a cohesive group. The retreat incorporated a comprehensive review of the DEI membership survey that you completed (n=168 member responses). Thank you for your participation in this important assessment. I look forward to presenting this data, along with our organizational activities of the past year, during AC21.

There are several other opportunities to participate in DEI initiatives at AC21, too. There will be a panel discussion on health disparities in cancer care during one of the BCOP sessions and the John G. Kuhn Keynote Lecture is entitled, “Dismantling Structural Racism in Pharmacy.” The keynote will be given by Lakesha M. Butler, PharmD, BCPS, Clinical Professor, Department of Pharmacy Practice; Diversity and Inclusion Coordinator, Southern Illinois University College of Pharmacy.

Dr. Butler was selected by our Annual Conference Planning Committee based on her national reputation. She is the immediate Past-President of the National Pharmaceutical Association (NPhA) and a national leader in promoting diversity initiatives.

Annual Conference 2021
By now, many of us are experiencing virtual fatigue and with the conference just weeks away, I wanted to highlight how our online meeting will come to life.

You will still get the historically excellent hematology/oncology education and professional networking you’ve come to expect. And, there will be plenty of industry collaboration and member research, along with social connectivity – in every sense of the word.

A 3D virtual platform called 6Connex will foster engagement and minimize virtual fatigue. With gamification, social networking and connection, and real-time meeting analytics, we hope to create the same environment Portland would have provided (minus the rain).

I’m personally very excited about the Patient Advocacy Town Hall, which will be facilitated by the Patient Outreach Committee led by Jennifer Powers and James Connelly. Special acknowledge­ment goes out to everyone making the patient town hall possible. I look forward to seeing my “old” professional colleagues, as well as many of our new trainees, clinical specialists, administrators, and industry partners.

Transitioning to a HOPA Ambassador
This is my final HOPA News Board Update as President. It has been an honor to serve this wonderful organization. While serving in this capacity during a year when we changed management companies (during a pandemic), wasn’t always easy, I do feel fortunate.

I have been surrounded by a great team, including the HOPA Board, staff, committees, and many members whose support I have felt and appreciated. I want to personally thank outgoing Board members, Susie Liewer, Sally Barbour, and Jeremy Whalen for their insight, activity, and commitment to our organization.

Soon, I will assume the role of Past-President but specifically will engage as a HOPA Ambassador. I am looking forward to this new role and will continue to strive to advance our organizational mission, advocate for cancer patients, engage in committee activ­ities, mentor members as needed, and most importantly promote positivity.

At the Annual Conference, Larry Buie will assume the role of HOPA President and I am eagerly looking forward to his leadership. For now, your “virtual” President is signing off.


Launching an Oral Chemotherapy Telehealth Clinic Using the TAMER Model

Background
Oral chemotherapy—also known as oral oncolytics—has been available for nearly seven decades.1 Today, up to 35% of new on­cologic agents in the pipeline consist of oral formulations.1 As of December 18, 2020, the Food and Drug Administration (FDA) had 56 treatment approvals for cancer indications; of which 23 were oral chemotherapy.2

There are many established safety and quality standards for intravenous cancer treatments. Patients treated with intravenous cancer therapies at a cancer center have scheduled visits and are closely monitored. Conversely, national guidelines and workflows for oral cancer therapies vary immensely based on the institution, and continue to be a work in progress. Oral chemotherapy offers cancer patients more flexibility, less disruption to their daily lives, and more autonomy.3 Nevertheless, the effectiveness of these ther­apies depends greatly on patients’ adherence. Common barriers to patient adherence include complex administration instructions, limited knowledge about the therapy and adverse events, low health literacy, and financial toxicity.4

As these therapies become widely prescribed, it is vital to identify current oral chemotherapy practices at local institutions and learn from successful programs and best practices published by national guiding bodies. Developing a workflow to manage patients on oral chemotherapy requires multidisciplinary col­laborative efforts between pharmacists, physicians, advanced practitioners, nurses, social workers, and financial navigators. These efforts require significant staff time to assure patient access to medication, adequate education, proper adherence, and adverse event monitoring, as well as side effect management.

The biggest challenges to implementing oral chemotherapy services are monetary, such as significant non-billable staff time, especially when medications are sent to an external pharmacy and the cancer center receives no compensation in return.5 Successful programs, such as the one by Mancini and colleagues, have profit margins that accommodate a full-time pharmacist, full-time technician, and a full-time pharmacy billing specialist, all dedicated to an oral chemotherapy management program at a community cancer center.6 Oncology pharmacists are the experts on cancer drugs and can play a pivotal role in establishing and managing such programs. Yet, they continue to face financial hurdles of billing due to lack of provider status and the complexity of assigning a dollar value to the interventions and services they provide. Limited studies track the outcomes of pharmacist-led interventions in pro­moting adherence to, and safety of, oral chemotherapy, especially when oral chemotherapy is decentralized from the cancer center to the community or specialty pharmacies.

Telehealth in Oncology—Teleoncology
One way to overcome the challenges and limited resources for oral chemotherapy is to implement teleoncology, which is the applica­tion of telemedicine to advance cancer care, including diagnostics, treatment, and supportive care.7 Disparities in cancer care delivery between intravenous and oral chemotherapy can be improved by establishing telecommunication infrastructure—for example, an oral chemotherapy telehealth clinic, run by clinical faculty con­tracted with a community cancer center, and staffed by pharmacy trainees.

The World Health Organization (WHO) and the American Tele­medicine Association underscore the use of telecommunication to promote health. While telemedicine has gained popularity during COVID-19, lessons learned from this experience may live long beyond the pandemic. Deploying patient-provider telehealth along the oncology care continuum was successfully implemented during the pandemic by a group of providers in California, who highlight­ed the critical need to further investigate the role of telehealth, not only during crises, but also to improve our routine care of patients with cancer in the future.8

Older Oral Chemotherapy Patient Management at Our Cancer Center
The following outlines an oral chemotherapy telehealth clinic launched by clinical oncology pharmacy faculty and pharmacy stu­dent trainees from the University of Missouri Kansas City (UMKC) School of Pharmacy at Advent Health Cancer Center in Shawnee Mission, Kansas.

In an effort to standardize practice across the different clinics and switch from paper charts to a centralized online tracker, the oncology pharmacist had already proposed a new workflow related to the care of patients taking oral oncolytics. The cancer center management team and providers endorsed the proposal and agreed to pilot it; unfortunately, the pandemic delayed the start date. However, various clinical support staff began working remotely, so management suggested that they could partially implement the proposal and switch patients on oral chemotherapy from paper charts to an online tracker.

The oncology pharmacist developed a training video to help navigate the switch from paper charts to the online tracker utiliz­ing the Microsoft Teams platform to include all patients stratified by provider. Data collected in the tracker included the following: patient name, medical record number (MRN), diagnosis, oral oncolytic prescribed, prescription date, dose, insurance provider, specialty pharmacy, patient assistance program, date prescription sent, date prescription received, dates of initial consultation and follow-up with a PharmD, oral chemotherapy initiation date, week 1 through 4 follow-up assessment (by nurse practitioner or PharmD), monthly assessment, telehealth follow-up visit, and notes.

Piloting the New Oral Chemotherapy Remote Patient Monitoring Clinic
Phase I → Switching all patients on oral oncolytics from paper charts to the online tracker
Phase II → Following up on all existing patients via a telehealth visit using the pharmacy consult described below
Phase III → Establishing a standardized workflow for all new patients starting oral oncolytics

The completion of phase I allowed us access to all patients on oral oncolytics in one location. This was followed by developing a phar­macy consult note (including assessment of adherence, adverse events, medication-reconciliation, and a quality-of-life question­naire) that was approved by providers who wished to enroll patients in this service. We explored multiple telehealth/telemedicine synchronous technologies during the pandemic. These included using the patient portal virtual visits, considering HIPAA protected Zoom, Microsoft Teams, and other mobile applications. Technology challenges included cost, image/sound quality (depending on in­ternet quality), lack of internet and video access for some patients, difficulty remembering scheduled virtual appointments for both patients and providers, patients struggling to use the technology, and the need for more provider training. Phone calls with video ca­pability by patient request worked best for our patients, and hence, was adopted for this telehealth clinic.

Subsequent steps involved training fourth year pharmacy students who were on their advanced pharmacy practice experience (APPE) month-long oncology rotation, and establishing a timeline to cover all patients. The steps below describe the pharmacy students’ training model developed by our faculty.

Student Training—TAMER Model

1. Teach:

  • Students learn about the consult note. Each element of the note is reviewed in detail during their first week of rotation.
  • Students are assigned patients to work up on Friday.
  • Students are instructed to prepare for Monday telehealth visits and set the intention for meaningful and efficient interactions over the phone.
  • Students are encouraged to have the patient’s EMR open during the call, as well as multiple databases (drug resource, herbal database, adverse event grading tool) that may be needed.
  • Students are provided phone scripts approved by cancer center to introduce the call/telehealth service and to leave messages if patients don't answer.
  • Students are instructed to inform faculty immediately in the event a patient discloses any adverse event greater than grade 1.
  • Management of grade 1 adverse events such as nausea, diarrhea, constipation, fatigue, and pain are discussed in details and may be addressed during the telehealth visit.
  • Students are encouraged to explore cues (unreported adverse events as well as issues identified regarding physical, social, emotional, and functional wellbeing) from the quality of life questionnaire built into the visit.
  • Students will complete the consult notes on Monday afternoon. Any interventions are discussed with the faculty and then relayed to the corresponding provider in person on the same day. Faculty will then review all the notes and send edits back to students.
  • Edited/reviewed notes are then added to patient’s EMR by the students, co-signed by faculty and forwarded to corresponding provider.

Medical and Gynecologic Oncology

2. Assess Preparedness: The subsequent Monday, the faculty will discuss all the patients that students worked up on Friday and address any questions the students may have prior to any phone calls.
3. Modeling: Faculty models one real patient consult in real time while students shadow.
4. Example: Students then contact their first patient while faculty is present. Faculty may assist during the call if needed, and after completion of the call, faculty will review what went well and what can be improved with the students.
5. Repeat and learn: Students get to participate in this telehealth clinic for three to four Mondays during their rotation.

Challenges
We knew that implementing this new initiative during a global pan­demic would be uniquely challenging. Nevertheless, with the collab­oration of all cancer team members, we piloted this program with a few providers starting in June 2020. We are currently in the process of retrospectively collecting all the consultation data. This data will be discussed at provider meetings in an effort to get feedback and standardize the management of all patients on oral chemotherapy. A new chemotherapy workflow was developed and scheduled to begin in January 2021. All patients who start oral chemotherapy will be instructed to contact the clinic when they receive their med­ication to set an initial education/drug-interaction check visit with the oncology pharmacist in person or via telehealth. All patients will have weekly follow-up calls with an oncology pharmacist for the first cycle of therapy; and with a nurse practitioner or clinic nurse for subsequent cycles. Cancer center management and pharmacy will analyze the metrics and explore ways to improve and standard­ize prescribing and dispensing of these agents.

Closing Remarks
Establishing new, standardized workflows for an oral chemotherapy clinic, in the middle of a pandemic, challenged everyone involved to better observe the needs of their local sites and identify opportuni­ties to innovate with limited resources. Using the TAMER model, our initiative to improve and standardize the oral chemotherapy work­flow can lead to improved patient care and outcomes, while also pro­viding a no-cost critical training opportunity for pharmacy students.

Teleoncology is a valuable service that can be utilized by pharmacists to provide access to quality cancer care with minimal disruption to cancer patients. We will continue to identify and measure quality metrics from this new workflow in order to further develop and refine processes to better serve cancer patients.

New Year, New Goals: Six Keys to Surviving and Thriving

It may be a bit cliché, but there’s something about the new year that stirs up nostalgia for what has passed and anticipation for what lies ahead. As that time of year rolled around again, I scrolled through my social media posts from the past year. At the end of December 2019, I was reflecting on my oldest child’s upcoming 10th birthday, and appreciating all of the change that had happened in that decade. I then came across a photo of my accounting text book, with the caption, “New year, new goals!” I was excited to be starting on my MBA degree. After being out of school for over 13 years, and having four kids in the meantime, I knew that this would be a challenge, especially on top of a full-time job. But I was up for it—it was time to move forward with this monumental goal. Little did I know just how challenging 2020 would be!

Storms are Coming
As I continued scrolling through my 2020 social media feed, a photo of a beautiful sunrise caught my eye. I had captured the red and purple sky, a sure sign that storms were brewing, on my way into work one morning. My caption said, “Storms are coming, but storms can be beautiful, too!” The date was March 11, 2020. Later that day, the first presumptive case of COVID-19 was detected in my state.1 Yes, storms were coming, indeed! In an instant, life turned upside down.

In those early days of the COVID-19 pandemic, change seemed to be happening at a faster rate and on a larger scale than many of us had experienced in our lifetimes. “Unprecedented” seemed to be the most fitting word. Across the nation, schools and businesses closed while parents navigated remote learning and childcare challenges. Employees and employers struggled with the drastic impact on the workforce and the economy.

For those of us in the healthcare industry, there were added challenges; we learned to care for COVID-19 patients, strug¬gled with capacity and staffing challenges, and worried about protecting ourselves and others with a less-than-adequate supply of personal protective equipment (PPE). We navigated the medica¬tion supply chain and educated the general public.

Surviving the Storm
In the midst of daunting obstacles, it was amazing to witness the response of so many creative, hard-working, and resilient people. Every day, I was impressed by the ingenuity and teamwork of everyone at my institu¬tion—from frontline workers all the way up to the C-suite.

Change was happening quickly; often, new policies were developed, only to be changed as more information became available. Every aspect of our jobs seemed to be under scrutiny and subject to rapid and drastic change, including scheduling and staffing, HR policies, COVID-19 treatment guidelines, infection prevention strategies, visitor policies, and daily screening practic¬es, among many other things. But with each new change, we rose to the occasion, and found creative ways to solve one problem after another, even if we had to re-solve them in a new way the next day.

How to Move from Surviving to Thriving
Looking back at the response of our institution, University of Arkansas for Medical Sciences—and specifically the pharmacy department—I can pick out a handful of factors that I believe were keys to not just surviving this period of unprecedented change, but thriving through it.
First, excellent leadership. This was crucial both at the institu¬tional level and from our Chief Pharmacy Officer (CPO). Frequent communication was also key. From the beginning, our CPO set up a regular cadence of meetings with department leaders. For a peri¬od of time, we met daily to discuss every aspect of the pandemic’s impact on patient care, pharmacy and hospital operations, and our personnel. This allowed us to collaborate across the department to creatively and quickly solve and anticipate problems. The impact of COVID-19 was not uniform in all areas—for example, in oncology areas, patient care was mostly business as usual. But making sure leaders and clinicians from all areas of the department were included in the daily meetings allowed for a unique opportunity for people to volunteer time and resources to meet needs in other areas.

Additional noteworthy keys for success were flexibility, resourcefulness, teamwork, and resiliency. As pharmacists, we are accustomed to dealing with constant drug shortages, tight staff¬ing, evolving treatment guidelines, changing policies, emerging technologies, and new institutional initiatives. While this pandem¬ic stretched these challenges to the limit (and beyond), we were able to pull from past experiences, and apply lessons learned to the challenges at hand.

Lessons Learned
On a personal level, living, working, and leading through this pan¬demic has provided ample opportunity for reflection and growth. Am I leading and caring for my team (and my family) with empa¬thy? Is information timely and delivered in a way that is mean¬ingful and reassuring? How can I creatively manage resources to ensure patient care continues safely and as seamlessly as possible? Am I taking care of myself, so that I will maintain resiliency? How can I continue working toward goals—organizational, profession¬al, and personal—during these trying times?

In times of crisis, these considerations are vitally important. The reality is, however, that they were just as critical pre-pandem¬ic, and will continue to be in the future. Realizing that, I spent time reflecting on how I could leverage these lessons learned into practical tips for navigating future challenges—both large and small. Here is my own personal list:

  1. Be empathetic. Everyone—patients and caregivers, teammates and employees, leaders and administrators—has struggles. Empathy and kindness are crucial to building trust. Be willing to give people the benefit of the doubt whenever possible.
  2. Communicate regularly and effectively. Ensure that communication happens in a way that is meaningful to the recipients. Take time to listen and let people know you care. At work, consider utilizing multiple forms of communica­tion, such as daily huddles, staff meetings, emails, bulletin boards, electronic communication boards, and whenever possible, one-on-one conversations.
  3. Be flexible. Volunteer to help in other areas if possible— not only will others appreciate the help, but also it can be personally invigorating. Be willing to change processes to meet new challenges. Think outside the box to solve problems creatively. Be patient with yourself and others when things do not go as planned.
  4. Be resourceful. Make the best use of resources (personnel, PPE, medications, etc.). Be creative in filling gaps. If possi­ble, consider leveraging volunteers or students on rotation to help meet needs during staffing shortages. Consider cross-training and/or reallocating staff to areas of highest need. Find creative ways to conserve supplies and protective equipment. Stay on top of potential drug shortages, and explore every channel for procuring critical medications.
  5. Prioritize resilience. Know when to take a break. Ask for help when you need it. Spend time with loved ones. Engage in hobbies. And make it a priority to rest and relax.
  6. Do not lose sight of goals. During times of crisis, we often default to survival mode, which is a natural response. However, it is important not to forget about the goals you have set. Whether it be learning a new skill, furthering your education, pursuing a hobby, improving your health, or finding a new job, it is important to keep them in mind. While your time and attention might be pulled elsewhere during a true crisis, it doesn’t mean that all of your goals need to be on hold indefinitely. Consider how you might be able to continue making progress, even as you face challenges.

Bright Spots
Though 2020 was not what any of us expected, it was an oppor¬tunity to highlight just how strong, caring and resilient we are as a profession. In spite of all of the challenges—juggling work and family concerns, starting a graduate degree program, facing many unknowns, losing loved ones—I find myself in a nostalgic frame of mind.

I am grateful for the bright spots of 2020, and I am hopeful and excited as I look toward the future, whatever it brings. I’ll take the lessons learned, and continue my own personal journey toward being the best that I can be. If there’s been any constant in my career as a pharmacist, it’s that change is inevitable. Learning to not only survive it, but also embrace it and thrive through it, is indispensable!

Responding to the COVID-19 Pandemic—Impact in Oncology Pharmacy Practice

Sylvia Bartel, MPH, RPh
Vice President of Pharmacy
Dana-Farber Cancer Institute
Boston, MA

During the COVID-19 pandemic, healthcare institutions and phar­macies worldwide have experienced significant challenges that have forced them to alter their standard operational and clinical practices. The shortage of personal protective equipment (PPE), which received widespread media attention early on, was merely the beginning. Across the globe, healthcare organizations have reported other con­sequences of the pandemic, including delayed access to cancer, anti-infective, and support­ive care medications, as well as a decrease in clinical trial referrals.1 Some institutions have also paused certain preventive services and cancer treatments.2 For example, breast, colon, and cervical exams decreased by 60% between mid-March and mid-June of 2020.3 Similarly, 44% of breast cancer patients re­ported delayed treatments.3 And like many other businesses worldwide, healthcare in­stitutions have laid off non-critical staff and reassigned others to areas in the organization with which they are less familiar.1,4

In response to these challenges, and to keep patients and staff safe, healthcare institutions implemented rigorous infec­tion-control practices and altered standard procedures. In addition to wearing face masks and practicing physical distancing—minimal preventive measures endorsed by numerous governmental health agencies—healthcare providers and pharmacies have installed plastic barriers at public ser­vice counters and increased telehealth options to deliver patient care, education, and medication reconciliation services.1,4,5 Pharmacies have adopted alternative methods for dispensing and administering medications in response to supply shortages and to limit contact between healthcare staff and patients. For example, some oncologists have reduced the number of patients on myelosuppressive medica­tions.1 They may prescribe smaller doses of medications that cause neutropenia, or delay administration of these medications to limit the number of patients who require follow-up care.4 Other oncolo­gists have transitioned patients from intravenous to oral medications whenever possible.1,4 To further reduce patient and staff contact, pharmacies have created self-service dispensing locations, set up curbside pickup, and mailed medications to patients.4

The COVID-19 Response at the Dana-Farber Cancer Institute
Throughout the COVID-19 pandemic, the Dana-Farber Cancer Institute (DFCI), like many other leading cancer centers, has been impacted both clinically and operationally. For example, the orga­nization established a hospital incident command center structure, which included the pharmacy, to disseminate rapid updates (once or twice daily) across all departments through weekly meetings, daily huddles, and email communication. The pharmacy created its own internal command structure to ensure rapid communica­tion between all areas of the pharmacy—infusion services, clinical services, and clinical trials/research pharmacy, outpatient/specialty pharmacy—and the rest of the DFCI healthcare team. Other insti­tution-wide changes that affected pharmacy operations included employee, visitor and vendor screening protocols, staff relocation, and remote work options. New PPE and medication conservation strategies required the pharmacy to closely monitor its stock and work collaboratively with DFCI’s supply chain team.

5 Ways COVID-19 Changed Pharmacy Operations
In addition to adapting to DFCI’s institu­tion-wide changes, the pharmacy revised its own operating procedures to ensure the saf­est protocols for medication preparation and dispensing. For example, we reduced the du­ration and frequency of on-site patient visits and decreased medication turnaround times, which was a goal we achieved early on in the COVID-19 pandemic and have been able to maintain since. To accomplish this, we have:

  1. adjusted where and how staff work,
  2. increased the number of medications prepared in advance for infusion therapy appointments,
  3. maximized use of the automated dispensing cabinet (ADC),
  4. used prescription delivery services to minimize contact between patients and staff, and
  5. adjusted medication administration—route, frequency, and dosage—to decrease the amount of time patients spend on site and to minimize their need for follow-up care.

Adjusting Where and How Staff Work
Approximately 40% of pharmacy staff have worked remotely since March. While those in leadership roles such as directors and man­agers and a portion of order verification pharmacists are working under a hybrid model that includes both remote and on-site hours, staff in clinical practice, research, informatics, and billing and regulatory compliance work entirely remotely. Clinical pharmacy specialists that have been working remote include those in the anti­coagulation management service, pain and palliative care, and oral chemotherapy teach areas.

While this has been successful overall, there are many challenges associated with remote work. Staff need the necessary technolo­gy—desktop/laptop, multiple screens, internet connectivity—to access to the institution’s clinical and operational systems. Com­munication methods (e.g. Microsoft Teams, Business Skype) with clinical teams and internal pharmacy department staff must remain secure and HIPAA compliance needs to be maintained. Additionally, it is important for remote workers to stay connected and engaged with on-site staff as well as to maintain a work-life balance.

There have been no noted changes in productivity or major issues identified. We have also reassessed and expanded staff roles. While everyone is expected to assist each other with tasks that fall outside of their usual responsibilities, some have taken on signifi­cantly more or different duties. For example, outpatient pharmacy technicians have provided coverage in the infusion pharmacy processing and material management areas.

Increasing the Number of Medications Pre­pared in Advance
Early on in the pandemic, pharmacy staff began to identify additional medications that could be prepared before patients arrived for infusion therapy appointments. Staff selected medications based on the drug’s stability, the likelihood it would be used (i.e., the patient would receive treatment as sched­uled to minimize waste), and the likelihood that physicians would not need to adjust the prescribed dosage. For medications that are weight based, such as trastuzumab and 5-Flu­orouracil, the doses were based on previous weight or body surface area as long as these remained within 10%. And now, we regularly prepare the following medications prior to patient appointments:

  • 5-Fluorouracil continuous infusion pumps
  • Herceptin Hylecta (trastuzumab and hyaluronidase-oysk)
  • Herceptin (trastuzumab)
  • Keytruda (pembrolizumab)
  • Opdivo (nivolumab)
  • Perjeta (pertuzumab)

Using a daily report, pharmacy staff identify infusion therapy patients and prepare medications for them in advance. For morning appointments, the medication is prepped by the end of the previous day; for afternoon appointments, prep is done in the morning of the same day. Pharmacy staff also manages delivery of the medica­tions to the infusion unit. By increasing the number of medications prepared in advance, the pharmacy hopes to reduce the amount of time patients wait for their appointments once on site. Since adding the aforementioned medications to our advance preparation list in August of 2020, pharmacy staff are already seeing a more efficient clean room operation because compounding occurs throughout the day instead of at peak appointment times (i.e., between 10:00 a.m. and 2:00 p.m.). Further, there has been minimal drug waste. The flat dose medications can be used for other patients, and for medications dosed by weight or body surface area, the 10% dose variation threshold has kept waste to a minimum.

In the coming months, we plan to review our metrics to determine preparation time for each medication, the number of physicians signing orders in advance, and patient wait times in the infusion therapy unit. We also continue to identify other medications that might be suitable for advance preparation and are working with physicians to determine whether exams and infusion therapy can occur on different days for certain types of treatments and patients.

Maximizing Use of the Automated Dis­pensing Cabinet
To minimize patient wait time and foot traffic in patient care areas and reduce compounding in the clean room, we have identified additional medications that can be added to our ADC. We have adjusted the periodic automatic replenishment (PAR) levels to reduce the frequency of restocking. Examples of medications we have added to the ADC include 4 mg doses of Zometa (zo­lendronic acid) and 120 mg doses of Xgeva (denosumab).

Using Prescription Delivery Services to Minimize Contact between Patients and Staff
In addition to delivering medications to our infusion therapy unit in advance of patient appointments, our outpatient and specialty pharmacy units are developing a process to dispense oral contrast medications to patients prior to their on-site radiology appointments. The units are also mailing prescriptions to patients both within Massachusetts and in other states.

Adjusting Medication Administration
Patients with cancer are at greater risk of experiencing acute COVID-19 symptoms and dying because cancer treatments often cause immunosuppression.1,2,3 Therefore, physicians are decreasing the frequency of treatments and prescribing fewer myelosuppres­sive regimens when possible. For example, Keytruda (pembroli­zumab) is often administered in 200 mg doses every 3 weeks, but we have been able to administer 400 mg doses every 6 weeks based on recent approval of an extended dosing interval. Physicians are prescribing Opdivo (nivolumab) in 480 mg doses every 4 weeks as opposed to 240 mg doses every 2 weeks as well. Patients are receiving Kyprolis (carfilzomib) weekly as opposed to twice weekly, and we have been able to substitute darbepoetin alpha (Aranesp) for epoetin alfa, its therapeutic equivalent, to reduce the treatment frequency. The utilization of standardized dosing supports the abili­ty to prepare medications in advance of a patient’s visit as well as avoid any potential medication dosage calculation errors. Explora­tion of other medications that are suitable for dose standardization along with dose banding is being further explored.

Physicians are also prescribing oral or subcutaneous admin­istration routes to reduce the frequency and duration of on-site treatments. Oral medications such as etoposide have been utilized for patients receiving intravenous etoposide on multi-day regimens. In addition, Ninlaro (ixazomib) has been prescribed instead of in­travenous Velcade (bortezomib). Examples of traditionally intrave­nous medications that are now available for subcutaneous delivery include Herceptin Hylecta (trastuzumab and hyaluronidase-oysk), Rituxan Hycela (rituximab and hyaluronidase human), Darzalex Faspro (daratumumab and hyaluronidase human-fihj) and Phesgo (pertuzumab, trastuzumab and hyaluronidase-zzxf). Physicians are also increasing prescriptions of Neulasta (pegfilgrastim) including the on-body injector, to avoid patients needing to return to clinic for an injection and to minimize the risk of febrile neutropenia. Though there has been a reduction in clinical trial referrals, we have been able to mail oral investigational medications to patients already on study therapy.

As DFCI moves into the next phases of its COVID-19 response, we plan to continue practicing some of the changes implemented in our pharmacy areas. We anticipate certain staff will maintain a remote work schedule and that telehealth will remain a convenient and appropriate option for certain patients or certain points in a patient’s treatment plan. Our advance medication preparation protocols have improved workflow in our clean room and, we believe metrics will show, have reduced patient wait times in the infusion treatment unit. Delivering clinical trial investigational and commercial medications to patients by postal mail has proved to be efficient for staff and convenient for patients. Finally, we have re­alized the indispensable value of data analytics for monitoring—in real-time—the effects of our new processes, creating performance targets, and identifying trends that will determine long-term operational changes.

The DFCI pharmacy staff have demonstrated remarkable resil­iency and flexibility during the COVID-19 pandemic; I am humbled by their commitment to our patients. I look forward to working with them as we continue to adapt—and improve—our processes.

The virtual fall 2020 American Society of Clinical Oncology (ASCO) Quality Care Symposium showcased methods for measuring and improving the quality and safety of cancer care, including the work of many oncology pharmacists. Quality healthcare domains, as defined by the Institute of Medicine (IOM) include safe, effective, efficient, equitable, timely, and patient-centered care.1 Measurement of quality care should be practical, meaningful, inexpensive, and user-friendly. Four abstracts demonstrating pharmacy leaders measuring and im­proving quality care for patients with cancer are highlighted.

Organizational Partnership to Expand the ASCO Quality Training Program (QTP) to Oncology Pharmacists2
Pharmacists are critical in optimizing medication management and quality care in oncology patients. The HOPA Quality Oversight Committee (QOC) sought to improve educational opportunities in the area of oncology value and quality-based patient care for phar­macists. This led to discussion and a partnership with the Ameri­can Society of Clinical Oncology (ASCO) Quality Training Program (QTP) to develop a one-day workshop tailored to oncology pharma­cists, aimed to strengthen their knowledge in quality improvement (QI) measures and strategies for practice improvement.

A pre- and post-workshop comparative assessment of attend­ees demonstrated the following on a 10-point scale: A 3-point improvement in knowledge and skills, and a 2.8-point increase in competence with 93% of attendees reported as very or extremely likely to use the new skills learned. The authors concluded that the workshop resulted in meaningful training in quality improvement measures for oncology pharmacists. Future partnership plans include additional one-day workshops and a modified ASCO QTP six-month course specifically for HOPA members.

State-wide Quality Improvement Addressing Overutilization of Neurokinin-1 Receptor Antagonists3
ASCO’s Quality Oncology Practice Initiative (QOPI) Symptom and Toxicity Module (SMT) metric 28a focuses on the overuse of anti­emetics, specifically of neurokinin-1 receptor antagonists (NK1-RA) for low or moderate emetogenic regimens. A team including oncol­ogy pharmacists created a quality improvement project to support a reduction in use of NK1-RA when not indicated. Baseline mea­surements of performance, prescriber knowledge and beliefs, and pre-populated antiemetic order sets were assessed.

A quality improvement intervention was initiated and included practice and state-level performance reporting to the Michigan Oncology Quality Collaborative (MOQC); chemotherapy-induced nausea and vomiting education, and a value-based reimbursement related to measure performance. Initial responses assessing pre-populated antiemetic order sets showed that 23% had NK1-RA or olanzapine in moderate emetic regimens. Post-education, 48% of respondents had plans to, or had already, rectified their order sets. This ultimately improved performance from 27% to 19% (p<0.05) and below the 2020 QOPI mean performance measure of 31%.

Development and Implementation of an Evidence-based Malignant Hematology Clinical Pathway Program4
Clinical pathways often include a systemic approach to clinical deci­sion support aimed at providing quality care while decreasing cost. Brahim and colleagues describe their institution’s implementation of a clinical pathways program to standardize practice and increase quality of care as measured by pathway adherence. A team of phy­sicians, pharmacists, nurses, a quality manager, and information technology staff worked together to create pathway algorithms and review treatment plans for acute myeloid leukemia. This included treatments, laboratory testing, and supportive care (antiemetics, antimicrobials, and tumor lysis prophylaxis). The primary objective was to achieve a pathway adherence rate of 80% or higher.

A retrospective chart review one year after implementation was completed to assess adherence. Forty-four pre-pathway implemen­tation patient charts utilizing best clinical evidence as a standard were compared to 44 post-implementation patient charts. There were 16 deviations pre-pathway. This included omitted medica­tions, medications added, dose variations, different regimens, and supportive care. There were five deviations in the post-pathway group. Deviations included omitted medications, added medica­tions, and different regimens. Pre- and post-pathway implemen­tation adherence was 64% and 89%, respectively (p=0.006). The investigators plan to expand their program to other disease states, such as multiple myeloma and acute lymphoblastic leukemia (ALL) while continuing to monitor adherence and program objectives.

Providing Uninterrupted Oral Oncolytic Therapies During the COVID-19 Pandemic5
The COVID-19 pandemic has created significant financial and lo­gistic hardships for patients and pharmacies to provide continued oral oncolytic therapy. A team investigated whether the pandem­ic impaired access to oral chemotherapy at Tennessee Oncology’s medically-integrated specialty pharmacy. In a retrospective analy­sis, investigators compared medication possession ratios (MPRs) of the 5 most common medications prior to and during the pandemic (January–May), as well as copayments and use of financial assis­tance resources.

Consistent MPRs were demonstrated for the five most common therapies analyzed in 2019 versus 2020 (95.13% vs 94.86%). They also found similar aggregated copay amounts between the study pe­riods and an increase in the use of copay cards (22%) and foundation assistance (12%) from 2019 to 2020. They concluded uninterrupted access to oral oncolytics and financial support services was provided throughout the beginning of the pandemic and attributed main­tained MPRs to proactive and strategically-timed patient outreach.

Conclusion
Oncology pharmacists contribute significantly to improving quality and value metrics in the care of patients with cancer. Assessment of quality metrics and engagement in value-based contracts contin­ues to grow and has become applicable to broader populations of patients with cancer in health-systems and oncology clinics. The impact of these on payment models continues to add pressure to meet these goals by the healthcare team including pharmacists. Re­gional and national publications and presentations aimed at quality improvement and research efforts will continue to show the value of the oncology pharmacist within patient-centered care.

Introduction
Thirty years ago, the human genome project began, led by an in­ternational team of researchers looking to sequence and map all genes—together known as the genome.1 Completed in April 2003, it allowed us, for the first time, to read Nature’s complete genetic blueprint for building a human being: around 3 billion DNA base pairs using a four-letter DNA alphabet.1 Subsequent efforts includ­ed profiling patient cancers and exploring germline (inherited) versus somatic (acquired through life) genetic mutations.2 Cancer is a disease of the genome caused by a cell’s acquisition of somatic mutations in key cancer genes, sometimes in addition to inherited germline cancer driving mutations, so these efforts provided great insight into how cancers progress.

Initial cancer genome research focused on protein-coding genes, which together account for approximately 1% of the genome.1 To address this issue, the International Cancer Genome Consortium/ The Cancer Genome Atlas Program (ICGC/TCGA) and the Pan-Can­cer Analysis of Whole Genomes (PCAWG) Project performed whole genome sequencing and integrative analysis on over 2,600 primary cancers. They have now profiled more than 10,000 tumors and generated valuable data that illuminates the complexities of several cancer types.3-5  In 2020, researchers released six papers in Nature and 17 papers in other journals that could pave the way for full ge­nome sequencing of all patient tumors.6 These sequences are being used in efforts to match each patient to a molecular treatment, the hallmark of precision medicine.

In the first part of the 21st century, twin revolutions in biotech­nology and computer science offer enormous promise for technol­ogy to improve our lives. Together, biotech innovations in editing the genome of humans and other organisms, and computer science advancements in machine intelligence and machine learning, have the potential to confer tremendous benefits on humanity. The combination of these two tools could potentially accelerate progress in cancer research dramatically. Various applications could include modelling the genesis and progression of cancer in vitro and in vivo, screening for novel therapeutic targets, conducting functional genomics/epigenomics, and generating targeted cancer therapies.7

Dr. Jennifer Doudna, a professor of chemistry and molecular and cell biology at U.C. Berkeley pioneered the discovery of the fanciest molecular-scissors of the century, which has enabled us to edit DNA and ultimately genomes. Dr. Doudna rocked the research world in 2012 when she and her colleagues announced the discovery of clustered regularly interspaced short palindromic repeats associated nuclease 9 (CRISPR-Cas9); a technology that uses an RNA-guided protein found in bacteria to edit an organism’s DNA quickly and inexpensively.8 In 2020, Dr. Doudna and Dr. Emmanuelle Charpentier, chair of the Regulation in Infection Biology Department at the Helmholtz Centre for Infection Research and a Professor at the Hannover Medical School in Germany, won the Nobel Prize for Chemistry for their work on this powerful gene editing system, increasing awareness of this technology.

What is CRISPR Gene Editing? 9,10
The process of CRISPR has actually existed for millions of years, having evolved to protect bacteria against viruses. The immune systems of certain bacteria use DNA sequences called CRISPR, which contain genetic material collected from viruses to which the bacteria have been exposed. When one of these viruses attacks the bacteria again, the matching CRISPR segment is copied to an RNA molecule that tracks down and binds to the virus’s own DNA, al­lowing a specialized cutting enzyme called Cas protein to chop off a piece of the viral DNA and kill the virus.

Once scientists learned how this worked in bacteria, they were able to extract CRISPR out of bacteria and reprogram the guide RNA to target any DNA sequence of the gene they wanted to alter. That sequence is then attached to a Cas enzyme (molecular “scissors”) to make cuts at the desired locations, adding or removing target DNA. In short, with this technology, we can rewrite the genome. And, this turned out to be simpler, cheaper, more efficient, more precise, and more flexible than previous gene-editing methods.

Somatic gene editing alters DNA of some of the body’s cells in humans to treat genetic conditions. Germline editing manipulates DNA in sperm, eggs, or embryos—affecting all or most-T-cells— and permitting the organism to then pass down those alterations to their offspring. In theory, rather than treating the disease, germline editing could eliminate the disease; and not just from the organism, but from its lineage completely.

A CRISPR Way to Screen for Cancer—A Sci-fi Dream or a Reality? 11-12
Aside from genome editing, CRISPR can also be used to help us rapidly and inexpensively read our DNA. This unexpected finding led to investigating the CRISPR-Cas protein system as a next-gen­eration diagnostic. While Cas9 acts as a precise molecular scissors to produce one cut, Cas12 uses its guide RNA to search billions of letters to find the matching DNA target. Once it does, it starts cutting without stopping just like a paper shredder. Such a protein can be paired with a molecular fluorescent reporter that is ignited when the protein starts shredding and, as a reaction, generates a colorful explosion indicating that the target is present. The reaction detection can be freeze-dried and paper-spotted to generate a visual readout on a lateral-flow test strip, which is cheap and can be used at home, similar to a pregnancy test.

The new diagnostic tool developed by Chen and colleagues could help identify bacterial and viral infections (such as COVID-19), detect cancerous mutations in real time, and recognize new outbreaks before they spread. Cas12 has already been used in vivo to detect the presence of cancer-causing human papillomavirus (HPV) types, a common viral infection that can cause cancers – most commonly cervical cancer. CRISPR-based HPV diagnostics have had almost perfect accuracy. Cas12 can search through fluids such as saliva, blood, or even urine for a specific DNA match in minutes, at the point of care. This has many implications, such as detecting or screening for cancer early, or even diagnosing a viral infection during a pandemic in a prompt, non-invasive fashion.

Moving CRISPR-Cas9 from the Lab to Cancer Patients
The first-in-human testing of CRISPR was in 2016 by Lu and col­leagues in China.13 They performed a Phase I clinical trial to assess the safety of CRISPR/Cas9-mediated knockout of PD-1 gene in autol­ogous T-lymphocyte therapy in patients with metastatic non-small cell lung cancer (NSCLC). The study enrolled 22 patients, 12 of whom were able to receive treatment. Two patients experienced stable disease, no grade 3-5 adverse events were reported, and off-target events were 0.05%. This has been followed by multiple ongoing CRIS­PR trials in China against esophageal, bladder, prostate, renal, and cervical cancers; as well as leukemia and lymphoma.14

The first-in-human CRISPR phase 1 clinical trial in the United States was launched in 2018 by Stadtmauer and colleagues.15 The study was designed to test the safety and feasibility of CRISPR-Cas9 gene editing of T-cells, from patients with advanced refractory cancer. The trial enrolled two myeloma and one liposarcoma patients. They reported observing the edited T-cells expand and bind to tumor targets with no serious side effects related to the investigational approach. These patients were heavily pretreated, and since the trial, one patient has died and the other two have had disease progression. This study was not designed for efficacy, and the number of patients was small. Yet, it represented a historical step in the use of CRISPR-Cas9 in cancer therapeutics.

Improving Current Cancer Treatments with CRISPR
CRISPR may be used to improve efficacy of chimeric antigen receptor (CAR) T-cell therapy.12 Applications under study include the genera­tion of HIV-resistant T-cells with homogenous CAR expression, gener­ation of allogeneic CAR-T-cells, and improving CAR-T cell function.12

Other active areas of study already in clinical trials include improving the efficacy of immunotherapy.23 Unleashing T-cells against tumors by blocking immune checkpoints such as cytotoxic T lymphocyte antigen 4 (CTLA-4), programmed cell death protein 1 (PD-1), and programmed cell death 1 ligand 1 (PD-L1) have been successfully used.23 Therefore, the knockdown of these genes using CRISPR, may be crucial to improve the efficacy of immunothera­pies.23 A PD-L1 knockout in mice with ovarian cancer using CRISPR promoted anti-tumor immunity by increasing tumor-infiltrating lymphocytes and modulating cytokine/chemokine profiles within the tumor microenvironment, thus suppressing ovarian cancer progression.24

Future Avenues and Perceived Challenges
Future innovation may include the collaboration of two revolution­ary technologies: CRISPR and artificial intelligence (AI). Machine learning based approaches to examine how changes in our DNA contribute to cancer already exist, and future CRISPR-Cas9 applied cancer therapeutics are likely to reach patients faster using AI to examine potential target and off-target DNA cutting outcomes and their implications.

CRISPR knockdown/knockout models may also offer a promis­ing novel therapeutic approach for cancers that lack effective treat­ments, such as cervical cancer.25 HPV-associated carcinogenesis provides a classical example for CRISPR-based cancer therapies, since the viral oncogenes E6 and E7 are exclusively expressed in cancerous cells.25

Ethical concerns aside, when used for single-gene diseases or cancer, this technology may be the next breakthrough in genetic linked chronic diseases including cancer. Major safety concerns include but are not limited to the unknown long-term consequences of DNA manipulation and the irreversibility of this procedure. Prac­tical and clinical challenges may include side effect management, especially if off-target effects take place; routes of administration; insurance coverage; and affordability. With every new cancer therapeutic modality that is innovated, there is both accompanying promise and peril. Hence, the opportunity for oncology pharma­cists, with their crucial role of collaborating in healthcare teams, to make a difference addressing these concerns.

The effects of innovation are felt around the world. When it comes to medicine, the pace of that change is rapid, especially in oncology, and it’s only moving faster. Remarkable opportunities for good can also be misused. Both malicious intent and unintended consequences can create a real risk of harm for individuals, society, or both.

In 2018, He Jiankui, a Chinese geneticist, claimed to have used CRISPR-Cas9 on a set of twins and a third baby to make them HIV-resistant via editing of their CCR5 gene to create a resistance polymorphism in the children that had previously been seen in nature. His experiments were widely condemned as premature and irresponsible. A commission was formed and on September 3, 2020 the International Commission on the Clinical Use of Human Germline Genome Editing released a 225-page report that offers a guide to the available testing and regulations, as well as the state of current research, and concluded that gene editing of human embryos is not yet reliable enough to use on humans in an ethical way.26  Written by dozens of scientists world-wide, the report stated that any country that permits its scientists to do so should limit the activity to severe, single-gene diseases such as sickle cell anemia, cystic fibrosis, or Tay-Sachs.26

Closing Remarks
Gene editing and AI can radically change cancer therapeutics and is likely to have thousands upon thousands of applications. I believe that this potential for broad and rapid impact is at a scale that has rarely been witnessed in human history. The speed of these changes hastens an already urgent need for discussion on the plans for what to do when there are unmet therapeutic needs and when to proceed with caution especially when it comes to germline gene editing and unknown long-term consequences.

This is an exciting time to be practicing in oncology, witnessing novel therapeutics unfold, and providing new hope for our cancer patients. Yet, it is also a humbling experience that constantly reminds us that we are forever students, and our duty is to pass on this knowledge after we acquire it and consider not only its therapeutic implications, but also its ethical ones. As these tech­nologies are pushed forward, so is our hope to see more scientists in government. There is a need to advocate for more diversity in our representatives to include scientists that can take the lead on these advances, and bridge the gap between science and policy via interdisciplinary collaborations.

Lastly, while using CRISPR in principle to cure sickle cell disease or some cancers may be a dream within reach during our lifetime, it’s not going to do much good if that technology is expensive and remains out-of-reach for the majority of patients. Therefore, the key to moving forward is to take this very exciting development and deploy it in a biomedically ethical, clinically responsible, and patient-affordable way.

Introduction

We asked one postgraduate year 2 (PGY2) oncology residency program director and two clinical pharmacy specialists to give our trainee readers tips on how to ensure a successful virtual interview. The result was different perspectives, from both the interviewer and interviewee points of view, based on their personal experiences. We hope you gain valuable insight from LeAnne Kennedy (inter­viewer), Belinda Li (interviewee), and Jessi Edwards (interviewee).

Before the Interview

What are the most common platforms utilized for a virtual interview?
LeAnne:
Zoom and Webex are the most common platforms used by businesses, but there may be unfamiliar platforms too. You should be flexible and prepared for the unexpected and be gracious if things don’t go smoothly.

Belinda: The interviewer will typically send an invite in advance so you can familiarize yourself with whichever platform they’ll be utiliz­ing for the interview. Practice using the platform before the date of interview if you’re unfamiliar with it.

Jessi: If you are familiar with the platform, it never hurts to per­form a test run prior to the interview. Ensure you’ve installed the most up-to-date version of the platform on your device to avoid having to install/update the platform on the day of the interview.

Which type of audio or video connection is best (i.e., laptop vs. webcam and wearing headphones vs. computer audio)?
LeAnne:
The most important thing is that you can hear and be heard. Make sure that all devices are charged and connected.

Belinda: If you have any distractions at home during the interview (e.g., children, pets, etc.), wearing headphones may help block out noise and keep your attention focused on the interview. Otherwise, just make sure you have a strong internet connection.

Jessi: It depends on your situation. I shared an office with other pharmacists during a recent virtual interview, so I scheduled my in­terview at a time I could be at home to avoid distractions and back­ground noise. Additionally, I knew my internet connection at home was reliable so I would have a stronger internet connection.

What is the preferred background and/or location for a virtual interview?
LeAnne:
The key is to be somewhere that you will not be distract­ed or interrupted. Find a plain background or at least something that is not distracting. I would not recommend moving from one location to another due to the chances of computers not connecting with each move.

Belinda: You need to be somewhere you won’t be distracted so you can stay engaged with your interviewers. If you have a private room where you can shut the door, that would be best. Plain and simple backgrounds are less distracting to your audience, and make sure the room has enough lighting.

Jessi: Do your best to find a private room and a blank background. I have even turned my home desk around so that the wall was be­hind me for a recent virtual interview.

What materials should the candidate have with them for a virtual interview?
LeAnne:
Since it isn’t a live interview, you won’t need a paper copy of your CV. If you have made changes to your CV since submitting application, then I would be sure to email a copy (in PDF format) before your interview. The most important things to bring are a smile, positive attitude, and thoughtful questions about the pro­gram, institution, and also about the local area.

Belinda: Be prepared to share screen, especially if you’re present­ing. Close out of everything else on the computer so you don’t accidentally share something else. Close out of your email and text notifications on your computer until the interview is complete.

Jessi: Turn off, or at least silence, your cell phone. Regardless of sharing a screen or not, your eyes may wonder if a text or email comes through, and this can make you appear disengaged or worse, you may miss a question or lose your train of thought. Just as with in-person interviews, having a notepad is good to take notes or to ref­erence if you have prepared your own questions for the interviewers beforehand. Nobody is going to fault you for being proactive.

What information should the candidate prepare for a virtual interview and how might this differ from prepar­ing for an on-site interview?
LeAnne:
I recommend reading the interview letter/email several times to be sure you know what is planned for the day. If you have questions about the day, be sure to ask before the day starts. A few common questions:

  • Will there be separate virtual sessions that you will need to log into?
  • Is there a contact if there are technical difficulties?
  • Will there be breaks built into the day for lunch and bathroom breaks?
    • Is there a a video to watch before the interview (overviewing the site or city)? If so, watch it so that you can follow-up with insightful questions.

Belinda: You should be prepared for your interview similar to an on-site interview. Most of the questions you’ll be asked will be the same as on-site interviews. It’s important to still dress professional­ly and remain engaged even though you’re not on-site. Many insti­tutions are still requiring presentations, so prepare for these as you would a normal interview.

Jessi: Just because you have a virtual interview does not mean you should prepare any differently. You should dress professionally and imagine as if you are in the same room as the interviewers. My recent virtual interview included more clinical questions, since a presentation was not required unlike other in-person interviews. I think there is an increased emphasis on preparing for those situa­tions beforehand if no presentation is required.

Are there any other differences in preparation for a virtual vs. on-site interview that you would like to highlight?
LeAnne:
It will be hard to convey your personality in a virtual interview, but it is important to be yourself as if you were there in the same room. Maintain professional posture and speech. Virtual interviews will help us all assess how adaptable we can be to different situations, so be flexible and gra­cious if things do not go smoothly.

Belinda: Virtual interviews may sometimes be one long continuous video conference with different people joining and exiting or have several sessions scheduled with differ­ent meeting invites. Make sure to keep track of which invitation you need to log into at the correct time and exit out of previous meetings when they are complete.

Jessi: Virtual interviews allow additional team members to attend when they may otherwise have been busy with patient care and unable to step away from their desk for an in-person interview. This means there are more people for you to ask questions of and get a better idea of the work environment and team dynamic. Take advantage of this opportunity by preparing broad questions that different pharmacists in different clinical areas can answer. On the other side of the coin, be aware that some of these pharmacists are multitasking on their end so while they may be attending virtual­ly, they may not be providing their undivided attention. Try your best to keep your answers, and questions, interesting so that they remain engaged and will remember your interview down the line when it is time to review candidates.

During the Interview

How can the candidate learn more about the city or town during a virtual interview?
LeAnne:
This is very important since you will not be there to tourcity before and after your interview. Ask if they have a video that highlights their city or better yet, search for one yourself be­fore you have your interview so that you can ask questions based on what you learned.

Belinda: The candidate can always ask the interviewers about the city, such as areas to live and things to do.

Is it appropriate for the candidate to inquire about the possibility of an on-site interview?
LeAnne:
It is appropriate to ask for an on-site interview, but re­member it may likely not be possible at this time.

Belinda: If the position is local, I think that is a possibility. Many facilities are still limiting their visitors and are not allowing on-site interviews, but there could be a chance to meet with some of the pharmacists off-site, such as a nearby coffee shop with outdoor seating. Of course, this ultimately depends on everyone’s comfort with the situation.

In what other ways have your experiences with virtual interviews differed from on-site interviews?
Jessi:
It provides a disadvantage that you cannot visit the actual site and have one-on-one conversations with other staff. I feel like this is really where interview candidates are able to shine, because no matter how much clinical knowledge you have, you do not want to work with people with whom your person­ality does not mesh. To overcome this, I rec­ommend you do even more research before­hand so that you are prepared to ask specific questions about the facility and city as well as the work environment. It never hurts to ask questions! This helps keep the conver­sation going and allows you to get to know your potential coworkers. Also, as it is more difficult to convey your personality and get the feel of “good fit” virtually; you have to be very cognizant of letting your personality shine through the computer screen to the best of your ability. Don’t try too hard, but don’t let this strange interview experience hold you back. Virtual interviews are shorter so you have to use the time you are given to make sure you are the most memorable candidate.

After the Interview

How can the candidate say thank you after a virtual interview (i.e., card vs. email)?
LeAnne:
I am old fashioned and feel that a card is still a classy way to follow-up after an interview. When possible, send to each interviewer and if you don’t have their contact information, then ask the primary person to share your gratitude for the day. It is easier to send a card to each person since the mailing address is the same. When it comes to an email, in today’s world, this has become a standard way of com­municating and in a much timelier fashion. It is harder to get every­one’s email which then necessitates addressing the email to multiple people or asking that they pass along your message.

Belinda: Either form should be fine as long as you send some form of thank you. Personally, I prefer email since I know that it will actually reach the interviewers as mail can get lost, especially when sending to an office in the hospital. If you do send a card, make sure to do it immediately after the interview so that it can arrive in a timely manner.

Jessi: I don’t think it truly matters how you send a thank you as long as you DO send a thank you. If you are going to forget to mail a card or you don’t have any on-hand, an email is completely appro­priate. I like knowing that my thank you reaches the interviewer via email instead of relying on the post office, especially with the current mail delays.


Feature: Summary of Hepatitis B Virus Screening and Management for Patients with Cancer

Lindsay Orton, PharmD
PGY-2 Oncology Pharmacy Resident Vanderbilt University Medical Center
Nashville, TN

It is well known that patients with hematologic malignancies who receive anti-CD20 monoclonal antibodies or undergo a stem cell transplantation are at a high risk of hepatitis B virus (HBV) infec­tion. However, the risk of other anticancer therapies and cancer types (i.e. solid tumors) are not as well understood.

American Society of Clinical Oncology (ASCO)’s 2015 provision­al clinical opinion (PCO) recommended screening for HBV infection only in patients who start anti-CD20 therapy, undergo a stem cell transplantation, or have risk factors for HBV. These risk factors include persons born in countries/regions with a HBV infection prevalence >2%, United States-born persons not vaccinated as infants whose parents were born in regions with HBV infection prevalence >8%, HIV-positive persons, IV drug users, men who have sex with men, and persons with household or sexual contact with persons with HBV infection.1 ASCO has published an updated 2020 PCO.2 (Please see below.)

3 Key HBV Screening Recommendations for Patients with Cancer

In accordance with the American Association for the Study of Liver Diseases (AASLD), the expert panel defined HBV reactivation and hepatitis flare as outlined below.3

  • HBV reactivation from chronic HBV: 100-fold increase in HBV DNA compared with baseline, HBV DNA >1000 IU/mL if previously undetectable, or HBV DNA >10,000 IU/mL if baseline HBV DNA not available
  • HBV reactivation from past HBV: detectable HBV DNA and reverse seroconversion of hepatitis B surface antigen (negative to positive)*
  • Hepatitis flare: Alanine transaminase (ALT) increase >3x baseline and >100 U/L

*To simplify guidance, the 2020 PCO uses a cut-off threshold of HBV DNA >1000 IU/mL to warrant further management in patients with past HBV infection.

Recommendations

1. All patients with cancer expecting to start anti-cancer therapy (except hormonal therapy alone) should be screened for HBV via three tests: hepatitis B surface antigen, hep­atitis B core antibody, and antibody to hepatitis B surface antigen.
This recommendation represents the most significant change from the 2015 PCO. There have been several large, prospective clini­cal trials that have supported universal HBV screening compared to HBV risk-based screening. Brasseur et al. analyzed a survey of potential HBV infection risk factors in 388 patients with a solid tumor. The investigators found moderate sensitivity and specificity (46% and 56%) of the risk factor questions, however, a very poor positive predictive value (9%).4 Based on these results, use of an HBV risk factor approach for screening was discouraged.

Hwang et al. analyzed a 5-7 item and a 19-item HBV risk survey in 2,124 patients with a hematologic malignancy or solid tumor. Regardless of the number of items, the surveys resulted in high sensitivity (99-100%), but low specificity (<15%), which was attributable to the high likelihood of patients having at least 1 risk factor (i.e. older age, black or Asian race).5  Based on these survey results, almost 90% of patients would meet the criteria to undergo HBV serology testing, indicating that selective HBV screening is impractical and therefore universal screening is recommended.

A positive hepatitis B surface antigen (HBsAg) indicates chronic HBV infection whereas a positive hepatitis B core antibody (an­ti-HBc) demonstrates past HBV infection. However, chronic HBV patients will often have a positive anti-HBc, as well. Either a total immunoglobulin (IgM and IgG) or IgG should be used for anti-HBc testing. Positive IgM confers an acute infection and is therefore not recommended to be used alone for screening. The third test, anti­body to hepatitis B surface antigen (anti-HBs), indicates immunity. For patients with past HBV infection (anti-HBc positive), an asso­ciated positive anti-HBs represents a resolved infection whereas a negative anti-HBs indicates an isolated core. A positive anti-HBs with negative HBsAg and anti-HBc correlates with vaccine-induced protective immunity.

Anti-HBc positivity likely reduces the risk of HBV reactivation in patients with past HBV. A meta-analysis of 1,672 patients with past HBV (anti-HBc positive) identified a 14% reactivation risk when anti-HBs was negative compared to a 5% risk when it was positive.6 To note, HBV tests should be interpreted with caution in patients that have received IVIG, which has been shown to passively transfer anti-HBc leading to false-positive results. Therefore, patients should ideally be screened for HBV prior to receiving IVIG.

The panel recommends screening all patients prior to, or at the start of, anticancer therapy, however, the results of the screening test should not delay therapy. An exception to this recommendation is patients who receive hormonal therapy alone without systemic anticancer therapy. Hormonal therapy alone is unlikely to increase the risk of HBV reactivation in patients with chronic or past HBV and therefore, these patients do not require upfront HBV screen­ing. However, patients that receive steroids in addition to their hormonal therapy (i.e. abiraterone plus prednisone) could be at increased risk for HBV reactivation and therefore screening should be considered. In addition, if their regimen changes to include any additional anticancer therapy beyond hormonal therapy, patients should be screened for HBV prior to initiation or at the start of this new regimen.

2. Patients with chronic HBV receiving systemic antican­cer therapy should receive prophylaxis during – and for 12 months after – completion of their anticancer therapy.
Chronic HBV can lead to cirrhosis, liver failure, and hepatocellular carcinoma (HCC). The AASLD 2018 hepatitis B guidance reported approximately a 50% risk of HBV reactivation for patients with chronic HBV and a hematologic malignancy.3 Similarly, patients with HCC and chronic HBV are at increased risk for reactivation. Patients with other solid tumors and chronic HBV are also at a heightened risk, however, the data for HBV reactivation associated with the anticancer regimens used for these patients are limited. Until more data are available, the panel recommends that all of these patient groups receive antiviral prophylaxis starting before, continued during, and for 12 months after, their anticancer therapy if they are HBsAg positive.

There are currently 3 preferred medications for HBV prophylaxis because of their high potency and high viral resistance barrier: entecavir 0.5 mg daily, tenofovir disoproxil fumarate (TDF) 300 mg daily, or tenofovir alafenamide (TAF) 25 mg daily. However, due to their ability to suppress replication but not eliminate the viral genome, long-term therapy is required. Given their additional an­ti-HIV properties, prior to starting entecavir, TDF or TAF, patients should be tested for HIV. Monotherapy is not recommended for patients who test HIV positive.

While on antiviral prophylaxis, patients should be monitored by checking alanine aminotransferase (ALT) and HBV DNA level at baseline and every 6 months during their antiviral therapy. Due to the risk of hepatitis flares, ALT should be monitored monthly for the first 3 months after discontinuation of antiviral therapy, and every 3 months thereafter.

3. Patients with a past HBV infection receiving anticancer therapy considered high risk for HBV reactivation should receive prophylaxis during – and for 12 months after – their last anticancer therapy dose.
Patients with past HBV still contain HBV DNA in their liver and are susceptible to reactivation only during potent immunosuppression. In contrast to chronic HBV, patients with past HBV (both resolved infection and isolated core) only require antiviral prophylaxis if they are considered high risk for reactivation, which includes receiv­ing an anti-CD20 monoclonal antibody or stem cell transplanta­tion. Similar to chronic HBV, these high-risk patients will receive antiviral prophylaxis with entecavir, TDF or TAF during and for 12 months after completion of their anticancer therapy.

Longer antiviral therapy may be warranted given the increased risk of reactivation for nearly 2 years following completion of anticancer therapy, especially in those that are anti-HBs negative, which confers a higher reactivation risk compared to anti-HBs positive patients. Seto et al. found a significantly higher rate of reactivation associated with anti-HBs negativity compared to positivity (68.3% vs 34.4%, p=0.012) among 260 patients receiving rituximab-containing chemotherapy.7 During antiviral therapy, monitoring includes HBV DNA and ALT obtained at baseline and every 6 months.

Alternatively, patients may undergo close monitoring with HBsAg and HBV DNA every 3 months instead of pre-emptively initiating antiviral prophylaxis in all high-risk anti-HBc positive patients. In this approach, antiviral prophylaxis should be promptly started at the earliest sign of HBV reactivation (reverse HBsAg seroconversion or HBV DNA >1000 IU/mL). Seto et al. analyzed 83 past HBV patients receiving anti-CD20 therapy. Patients were monitored monthly without antiviral prophylaxis, which resulted in a 25% reactivation rate. Upon reactivation, patients were started on antiviral therapy and monitoring increased to every 2 weeks. All patients that received antiviral therapy had normalization of ALT and a return of HBV DNA to undetectable levels.8 If HBV DNA is quantifiable but still <1000 IU/mL, monthly monitoring of HBV DNA may be warranted. Upon initiation of antiviral therapy, ALT should be checked at baseline and every 6 months while on therapy. Following discontinuation, ALT should be monitored monthly for the first 3 months and then every 3 months thereafter. This alternative approach may be considered for patients that are adherent to close and frequent follow-up, including the 12 months following completion of anticancer therapy given the risk of delayed reactivation.

Other Considerations

Vaccination
Patients who are negative for all 3 screening tests (HBsAg, anti-HBc and anti-HBs) and have never been exposed to HBV, are not im­mune, and therefore are susceptible to HBV infection. Vaccination may be recommended, however, there is insufficient data on vac­cinating immunocompromised patients and modified dosing regi­mens (i.e. doubling the dose or administering additional doses) may be warranted given the reduced humoral response in these patients. Some research suggests waiting 3-6 months following cessation of anticancer therapy to administer vaccines and 1-2 months following the final dose of the HBV vaccine series to test for anti-HBs.9,10

Cost
Financial burden for patients is a huge barrier to implementing these recommendations. Various cost effectiveness analyses have found a benefit for universal screening and antiviral prophylaxis for patients with hematologic malignancies at high risk for HBV reacti­vation, however, the analyses for solid tumor patients at lower risk for reactivation have been conflicting. More research on the risk of HBV reactivation for solid tumor patients is needed to determine the cost effectiveness of universal screening and prophylaxis.

In summary, the expert panel recommends screening all cancer patients for HBV prior to starting anticancer therapy, and initiating antiviral prophylaxis in all patients found to have chronic HBV or high-risk patients found to have past HBV.

Connection, Community, and Care Navigation through the Leukemia & Lymphoma Society

As humans, we are built for connection. We need it to provide sup­port, foster growth, and share life’s ups and downs. The needs of a person with cancer are no different; in fact, their need for connec­tion may be even more pronounced. However, finding someone who understands the cancer experience, and who can relate to specific concerns and provide validation, can be difficult. In addition, it is not always possible to find someone of similar age or diagnosis within your own hospital or even within your own community.

As pharmacists, we have all experienced the hunger patients and caregivers have for educational information and for someone to relate to their experiences. The Leukemia & Lymphoma Society® (LLS) is a patient advocacy organization that has identified this common gap and works to fill it by connecting patients and their loved ones to online support resources. The LLS mission is to “cure leukemia, lymphoma, Hodgkin’s disease and myeloma, and improve the quality of life of patients and their families.”

LLS Community: Virtual Support in Real Life
LLS Community connects more than 16,500 patients, caregivers, and healthcare providers through an online platform. Patients can also access a nurse navigator, social worker, or other information specialist to assist with care navigation. “No one should have to face a blood cancer diagnosis alone,” LLS writes on its website.

Through the LLS Community, people who are experiencing cancer can post questions, add comments and useful links, and perhaps most important, share successes. At their fingertips, LLS Community members have access to numerous educational resources and first-hand experiences from patients, caregivers, and healthcare providers from across the country.

In addition, members can join smaller groups dedicated to their specific diagnoses or most relatable to their personal demographics. Some small-group examples include groups for caregivers; parents; Veterans; Black, Indigenous, and other People of Color (BIPOC): and members of the LBGTQI community. There are even such niche groups as those interested in Fertility and Pregnancy.

These personal connections within the community can, at times, be more valuable than any educational resource. They can be a source of inspiration and hope for those navigating the cancer journey and its attendant problems like anxiety, loneliness and iso­lation. “Patients who are involved in the community have a greater opportunity to connect. Almost all patients join and say, ‘I need to meet someone else who is going through what I’m going through’,” explains Tricia Hernandez, Senior Manager of Community Engage­ment for LLS, and an 18-year lymphoma survivor.

5 Ways the LLS Online Community Creates Connections

Comprehensive Digital Support
LLS employs many strategies to foster engagement on their online community platform, such as posing a “Question of the Day” to pro­mote interaction and discussion. They also focus on sharing timely and relevant articles in the news feed; real-time posts from national meetings; and new literature on the effects of COVID-19 on cancer patients, for example.

Information is shared from the patient perspective, too. Any member is able to directly comment on, or add additional findings or questions to, a post, which creates more knowledge sharing on topics that impact their care.

In addition to the LLS Community, the organization provides virtual education programs, including a national blood cancer conference, national webinars, and local education sessions. Recent technology upgrades makes expert content and educational materi­als even more accessible to registered members during and after the initial presentations.

The LLS Health Manager™ mobile application gives patients the ability to track side effects, medications, questions, and food and water intake. The application will generate a report based on patient tracking and gives patients the option to share information directly with their caregiver and healthcare team. Like the LLS Community, this application allows patients and caregivers to take an active role in their cancer journey.

The Role of the Pharmacist
We all know navigating a cancer diagnosis can be overwhelming for all parties involved. These examples, through the lens of LLS, provide an overview of some of the many resources available through patient advocacy organizations. The more we can familiarize ourselves with available resources, the more we can continue to work together to provide the best support to our patients and their loved ones.

Retrospective Study Evaluating the Safety of Administering Pegfilgrastim on the Final Day of 5-Fluorouracil Continuous IV Infusion

Amber Draper, PharmD, BCOP
Oncology Clinical Pharmacy Specialist, GI Oncology
Clinical Coordinator, Oncology Pharmacy
Emory Healthcare, Winship Cancer Institute
Atlanta, GA

Introduction
5-Fluorouracil continuous intravenous infusion (5-FUCI) is admin­istered as a 46-48 hour continuous IV infusion (CIVI), on an every two week schedule. It is administered along with oxaliplatin and/ or irinotecan in chemotherapeutic regimens used to treat gastro-in­testinal (GI) malignancies, including colorectal, pancreatic and chol­angiocarcinoma cancers. When 5-FU is administered concomitantly with oxaliplatin or irinotecan, neutropenia is more likely to occur and can lead to negative outcomes, such as treatment delays and hospitalization for febrile neutropenia (FN).1,2 In these scenarios, pegfilgrastim (Neulasta®) can be administered to maintain dose intensity and density in patients with GI malignancies experienc­ing neutropenia. However, the package insert (PI) recommends that pegfilgrastim not be administered 14 days before, or within 24 hours following, administration of cytotoxic chemotherapy.3 For this reason, some payors are unwilling to pay for administration of pegfilgrastim on the same day as 5-FUCI pump disconnect.

Following the currently approved indications, GI cancer patients would require an additional clinic visit for pegfilgrastim to be administered on day 4, the day after 5-FUCI pump disconnect. This is both cumbersome and costly for our patients. The pegfilgrastim on-body injector could circumvent this problem; however, we have seen many payors preferring biosimilar products that do not have a similar delivery system. The study reviewed here, “Retrospective study evaluating the safety of administering pegfilgrastim on the final day of 5-Fluorouracil continuous IV infusion,” attempts to determine the incidence of grade 3-4 neutropenia and FN when pegfilgrastim was administered on the final day of 5-FUCI.4

In this study, charts of 300 patients who received pegfilgrastim on the final day of 5-FUCI at two cancer centers were reviewed for demographics (age, race, gender), cancer diagnosis, stage of disease, chemotherapy regimen, number of prior therapies, and prior radi­ation therapy. FN risk factors were accessed for each patient based on the National Comprehensive Cancer Network (NCCN) Myeloid Growth Factors 2017 guidelines. For each chemotherapy cycle (14 days), the following data were collected: chemotherapy adminis­tration date, pegfilgrastim administration date, number of days between pegfilgrastim administration, and date of next chemother­apy cycle. The number of treatment delays and dose reductions for any reason were also collected per chemotherapy cycle. To assess for myelosuppression, the absolute neutrophil count on day 1 of each chemotherapy cycle was documented.

A total of 1845 chemotherapy cycles were evaluated. Out of 300 patients, three patients experienced grade 3 neutropenia (1%) and 2 experienced grade 4 neutropenia (0.7%) when pegfilgrastim was administered on the final day of 5-FUCI. The risk of FN and hospitalization occurring in a patient receiving pegfilgrastim on the final day of 5-FUCI was 0.7% (CI 0.001-0.024). Patients receiving pegfilgrastim on the final day of 5-FUCI had an absolute risk of experiencing a treatment delay or dose reduction due to grade 3 or 4 neutropenia of 1.3% and 1%, respectively.

Clinical guidelines and the PI recommend administration of peg­filgrastim 24-72 hours after the administration of chemotherapy. However, due to logistical challenges and related costs, same day ad­ministration on the final day of 5-FUCI infusion is often preferred by providers and patients.5,6 The results of this study demonstrated that rates of grade 3 and 4 neutropenia were low when pegfilgras­tim was administered on the final day of 5-FUCI. Additionally, dose delays and reductions due to neutropenia were low when pegfilgras­tim was administered on the same day as chemotherapy. These data suggest that administering pegfilgrastim on the final day of 46-48 hour 5-FUCI does not increase myelosuppression or FN episodes.

Several prospective and retrospective clinical trials have examined the efficacy and safety of administering pegfilgrastim on the same day as cytotoxic chemotherapy with contradictory results. However, GI malignancies treated with 5-FUCI were underrepresented in a majority of these trials. The results of this retrospective review of patients receiving 5-FUCI suggest that administering pegfilgrastim on the final day of 5-FUCI does not lead to an increase in myelosup­pression or FN. Based on these results, same day administration may be feasible for this patient population; however, further studies are needed to confirm these findings.

Utilizing Abemaciclib in Combination with Endocrine Therapy in High- Risk Early Breast Cancer: The monarchE Trial

Breast cancer is the most common malignancy among females in the United States; there were an estimated 279,100 new cases in 2020.1 Globally, 90-95% of these patients are diagnosed with ear­ly-stage disease, which generally has a favorable prognosis with low risk of recurrence when treated with standard of care therapies.2 Of those diagnosed with early-stage disease, 70% have cancers that are hormone receptor positive (HR+) and human epidermal growth factor receptor 2 negative (HER2-).3

Although treatment can vary in each patient based on risk of recurrence, endo­crine therapy (ET) is the standard of care in the adjuvant setting for patients with HR+ and HER2- disease and is associated with a significant reduction in risk of recurrence and death. However, up to 20% of patients may experience disease recurrence within the first 10 years due to ET resistance.4

Patients with high-risk clinical and/or pathologic features, such as large tumor size, high histologic grade, lymph node involvement, or high Ki-67 score, are at a greater risk for recurrence.4 For this reason, optimizing adjuvant therapy to minimize the risk of early recurrences or metastases is vital to this population of patients.

Abemaciclib is an oral, continuously dosed, cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitor and has shown promise in attenuating ET resistance.5 It is approved for use as both monotherapy and in combination with ET for the treatment of HR+, HER2- metastatic breast cancer. These approvals were based on significant improvements in progression-free survival (PFS) and objective response rate (ORR) seen in the MONARCH-1, MONARCH-2, and MONARCH-3 trials, which supports an evalua­tion of abemaciclib in the adjuvant setting.6

The monarchE Trial
MonarchE was an international, open-label, randomized, phase III trial that investigated the addition of abemaciclib to standard adjuvant ET in patients with HR+, HER2-, node-positive, high-risk early breast cancer. High-risk features were defined as patients with 4 or more positive pathologic axillary lymph nodes or 1-3 positive axillary lymph nodes with at least one of the following: tumor size ≥ 5 cm, histologic grade 3, or a centrally assessed Ki-67 ≥ 20%.

Patients were randomly assigned (1:1) to standard of care ET with or without abemaciclib (150 mg twice daily for two years) and continued ET for 5-10 years as clinically indicated. Patients were stratified according to previous chemotherapy, menopausal status, and geographic region. Radiotherapy and chemotherapy (neoadjuvant and adjuvant) were allowed and randomization must have occurred within 16 months of definitive breast cancer surgery. Patients who received prior ET for the prevention of breast cancer, had previous CDK4/6 inhibitor use, and those with inflammatory or metastatic breast cancer were excluded.4

The primary end point was invasive disease-free survival (IDFS) and was measured from the date of randomization to the date of first occurrence of ipsilateral invasive breast tumor recurrence, local/regional recurrence, distant recurrence, death attributable to any cause, contralateral invasive breast cancer, or second primary non-breast invasive cancer. Secondary end­points included distant relapse-free survival (DRFS), overall survival (OS), and safety.4

Results
A total of 5,637 patients from 603 sites in 38 countries underwent randomization over a two-year period. Baseline character­istics were well balanced between treatment groups. Patients were predominantly female (99.4%) and postmenopausal (56.5%) with a median age of 51. Almost 60% of patients qualified for the trial for having 4 or more positive lymph nodes. Aromatase inhibitors (AIs) were prescribed as the first ET on study treatment in 68.3% of patients and tamox­ifen in 31.4%. At the time of data cutoff, 12.5% of patients had completed 2 years of abemaciclib, while 72.8% remained in the two-year treatment peri­od. The median follow-up time was 15.5 months in both arms.4

In total, there were 323 IDFS events observed: 136 (4.8%) IDFS events in the abemaciclib arm and 187 (6.6%) IDFS events in the control arm, with most events being distant recurrences. Abemaci­clib in combination with ET demonstrated a statistically significant improvement in IDFS versus ET alone with two-year survival rates of 92.2% versus 88.7%, respectively (HR 0.75; 95% CI, 0.60 to 0.93; p = 0.01). This equates to an absolute improvement of 3.5% in two-year IDFS rates and a 25% reduction in the risk of an IDFS event relative to ET alone.4

The combination of abemaciclib with ET also resulted in an improvement in DRFS compared to ET alone with two-year DRFS rates of 93.6% in the abemaciclib arm and 90.3% in the control arm (HR 0.72; 95% CI, 0.56 to 0.92; p = 0.01). Data for OS was imma­ture, but the study will continue to a final analysis.4

Adverse Effects
The safety profile of abemaciclib in the adjuvant setting was consis­tent with the known adverse effects (AE) reported in the meta­static setting. However, due to these AEs, 68.1% of patients in the abemaciclib arm required dose adjustments and 16.6% required discontinuation. The most commonly reported AE in the abemaci­clib arm was diarrhea; arthralgia and hot flash were most common in the control arm (two AEs that were significantly less common in those treated in the combination arm). Grade 3 or higher AEs occurred in 45.9% of patients in the abemaciclib arm and 12.9% of patients in the control arm, with serious AEs occurring in 12.3% and 7.2% of patients, respectively. The most frequently reported serious AE in both arms was pneumonia. Deaths while on study or within 30 days of treatment discontinuation were balanced at 0.5% in each arm.4

Summary and Implications
The phase III monarchE trial demonstrated a significant improve­ment in IDFS when abemaciclib is used in addition to standard ET in patients with HR+, HER2-, node-positive, early breast cancer with high risk of recurrence. These patients are at greatest risk for ET resistance within the first 2 years of adjuvant treatment, so a novel therapy to utilize in early-stage disease is warranted and could reduce the risk of resistance, recurrence, and metastases.4 Therefore, it is essential to recognize those with an increased risk of recurrence based on disease characteristics and identify when the addition of abemaciclib could be beneficial to these patients.

The monarchE trial represents an exciting new possibility for adjuvant treatment in early breast cancer, for which there have not been new advances in nearly two decades. On the basis of the results from monarchE, the addition of abemaciclib to standard ET should be considered in those with high-risk, node-positive, HR+, HER2-, early breast cancer. However, due to a short median follow-up of 15.5 months, additional follow-up is required to deter­mine continued benefit on later recurrences and overall survival for these patients. The benefit of abemaciclib in patients at low-risk for recurrence is unclear and further studies are warranted. Clinical trials are currently underway assessing the use of other CDK 4/6 inhibitors in high-risk patients with early breast cancer.4
