Board Update: A Candle in a Hurricane

You feel like a candle in a hurricane …”
Those words are the opening line of the 2007 hit “Stand,” by Rascal Flatts. It’s a song about overcoming obstacles in life. We’ve all had moments when we are challenged by forces seemingly bigger and stronger than ourselves—when our flame flickers to near extinguishment.
This metaphor came to life during the past months for many residents of the Gulf Coast, when Hurricanes Harvey and Irma wrought devastation across the region, most notably in Texas and Florida. Some HOPA members, including me, live and work in those paths of destruction. Our thoughts remain with those still recovering from the damage and loss inflicted by those storms.
HOPA, too, has been a circulating engine of energy, but with productive rather than destructive results. In early June, HOPA attended the annual meeting of the American Society of Clinical Oncology (ASCO), where we accomplished a great deal. HOPA President-Elect Ryan Bookout, Industry Relations Committee Chair Niesha Griffith, our HOPA Professional Relations and Development team of Julie Ichiba and Michael Bourisaw, and I met with several pharmaceutical industry partners to discuss current and potential professional collaborations. At this conference HOPA also participated in the first meeting of ASCO’s CancerLinQ Oncology Leadership Council (OLC). HOPA is an inaugural member of the group overseeing this health information technology platform, and we are fortunate to have Amy Seung serving as our representative on the OLC. Not surprisingly, several of our HOPA colleagues also attended ASCO to present their research relating to innovations in the management of cancer patients and delivery of cancer care within the healthcare system.
Also in June, HOPA introduced revisions to our committee structure. The changes made will improve our organizational functionality and facilitate more communication among groups with similar responsibilities for supporting our strategic plan.
June ended with HOPA’s participation in a timely meeting on biosimilars, therapeutic agents of importance to us as hematology/oncology pharmacy professionals. Edward Li, a HOPA board member at-large and a renowned authority on these entities, represented our interests at the PDA/FDA [Parenteral Drug Association/Food and Drug Administration] Biosimilars Conference in Bethesda, MD, June 26–27. In these discussions we were able to provide important feedback to regulatory agencies on the strategies required to successfully bring biosimilars to market.
You don’t have to be a Washington insider to predict stormy weather buffeting our nation’s capital. Each week seemingly brings a new development in the debate on healthcare reform. To help us stay the course through the storms, this summer our Public Policy Committee, chaired by Tim Tyler, issued “Principles of Healthcare Reform” (www.hoparx.org/advocacy-activities/position-statements), a position statement that frames our beliefs and serves as a foundation for our involvement. This group continues to monitor issues of importance to our practice and profession (such as pharmacists’ provider status and the 340B drug-pricing program) and ably advises us on advocacy opportunities.
HOPA’s 5th Annual Practice Management Program (PMP), chaired by John Valgus, was held in Chicago, September 15–16 (see Lindsey Amerine’s article on p. 19 in this issue for more details). Nearly 300 attendees gathered to hear presentations on issues affecting the implementation and support of pharmacy services, such as the Oncology Care Model, justification of oral chemotherapy services, and strategies to improve medication safety. This year our popular preconference workshop focused on the logistics of investigational drug services. To mark this milestone anniversary of PMP, the keynote lecture was named in honor of Past President Niesha Griffith. Niesha, a hurricane in her own right, has been instrumental in conceptualizing and developing the PMP since its inception in 2013.
At the conclusion of the 2017 PMP, we welcomed Michael Bourisaw as our interim executive director following the retirement of Suzanne Simons. Michael has worked with HOPA for the past 5 years and helped us develop diversified revenue streams and build relationships with other stakeholders. Just a few weeks into his leadership, we are already benefiting from his expertise in nonprofit operations and board governance. Michael has also been an asset to me personally, providing essential wisdom for guiding HOPA during this time of transition.
Finally, at the midpoint of my presidency, I leave you with a reflection on leadership, a pearl of wisdom once shared with me by my mom: blowing out someone else’s candle won’t make yours burn brighter. Encountering needless obstacles in our work can be challenging, to be sure. And it’s easy for the winds of change to knock us down or dampen our enthusiasm. But responsibly fostering innovation paves the way for meaningful growth and progress. As I noted at the end of my remarks as incoming president at our 2017 Annual Conference in March, working hard for something we love is called passion. I remain passionate about our organization and dedicated to you as members. We will encounter storms along the way, but I am confident that HOPA’s candle is poised to burn more brightly than ever.
Chimeric Antigen Receptor T-Cell Therapies: A Step Closer to Achieving the Magic Bullet in Cancer Treatment
Katie S. Gatwood, PharmD BCOP

Nashville, TN
August marked a historic milestone for both the oncology and medical communities with the first U.S. Food and Drug Administration (FDA) approval for a gene therapy, tisagenlecleucel (Kymriah).1 Tisagenlecleucel is the first FDA-approved chimeric antigen receptor T-cell (CAR-T) therapy and has pioneered a new class of “living drugs” in the armamentarium of anticancer therapy. CAR-T cells are T-cells that have been engineered to express antigen-specific receptors and are paired with a costimulatory domain that signals activation of the cell.2 CAR-T construct design has already undergone significant progress in the short time since the therapy’s inception, making possible improvements in both efficacy and safety.2 First-generation CAR-T cells possessed a ligand-derived extracellular domain and only a single signaling domain, making persistence of the cells a major limitation. The third- and fourth-generation CAR-T cells currently being tested in clinical trials have more sophisticated antibody-derived extracellular domains and three or four signaling domains.2 Thus far, the therapy has been most heavily studied in B-cell malignancies because, until recently, CAR-T cells could target only extracellular antigens and B-cells express well-established cell surface markers.2 Additionally, CAR-T cells can easily access the site of disease in B-cell malignancies because these cells are disseminated in areas of the body where T-cells naturally circulate, such as the bloodstream.2 The early but encouraging results of CAR-T cells in this setting have served as proof of concept for the therapy and incited rapid investigation of its application in a wider variety of cancers.
CD19 has been the most common target for CAR-T therapies developed to date and has been extensively tested in clinical trials. Tisagenlecleucel is a CD19-directed CAR-T product, and its breakthrough therapy approval comes after several years of investigation in relapsed or refractory B-cell acute lymphoblastic leukemia (ALL). The most recent data from the multicenter phase-2 ELIANA trial were presented at the European Hematology Association (EHA) Annual Congress in June 2017. The investigators reported that of the 63 pediatric and young adult patients in the trial evaluable for the primary end point, 83% (95% confidence internal [CI]: 71%–91%) achieved a complete remission (CR) or complete remission with incomplete blood count recovery within 3 months of infusion, with no detection of minimal residual disease at a median follow-up of 6.4 months, which may be suggestive of durability of response.3 Among responders, there was a 12-month relapse-free probability of 64% (95% CI: 42%–79%) and 12-month survival probability of 79% (95% CI: 63%–89%).3
Several other trials conducted in adult and pediatric patients with relapsed or refractory ALL have reported results similar to those of the ELIANA trial, with complete remissions ranging from 70% to 91%.4-6 One of these studies also demonstrated persistence of the CAR-T cells with sustained remissions and associated B-cell aplasia for up to 2 years following infusion without further therapy.5 CAR-T therapy has also been shown to be effective in patients who are refractory to the bispecific T-cell engager blinatumomab.5 In one trial, 3 of the 30 total patients had prior exposure to blinatumomab, and 2 of these patients were able to achieve a CR with CD19 CAR-T therapy. However, one of these patients eventually relapsed with CD19-negative disease.5 The authors felt that these results suggest that lack of response to prior CD19-directed therapy does not preclude success with CD19 CAR-T cell treatment. However, it should be noted that all patients included in this trial still had CD19-positive disease at enrollment.5
In other relapsed or refractory B-cell malignancies, CD19-directed CAR-T therapy has demonstrated mixed responses. A small number of patients (22%–50%) have achieved complete responses in CD19 CAR-T cell trials in chronic lymphocytic leukemia, mantle cell lymphoma, and follicular lymphoma, with a greater proportion of patients in these studies achieving only partial responses (PR) or stable disease.7-8 Positive results have also been observed in diffuse large B-cell lymphoma (DLBCL), where CAR-T therapy has demonstrated CR rates of 50% or higher with some durable remissions.9-11 Data from the interim analysis of the multicenter phase-2 JULIET trial were also presented at this year’s EHA Congress. Of the 85 patients included in the trial, 51 patients with multiply relapsed DLBCL were evaluable, and a CR rate of 37% and a PR rate of 8% at a median of 3.7 months postinfusion have been reported.10 Relapse-free survival at 6 months was 79%, and all patients who achieved a CR at 3 months maintained it until the time of data cutoff for the analysis.10 The phase-2 ZUMA-1 trial has also shown positive results in DLBCL, with a CR of 39% at a median follow-up of 8.7 months among the 72 patients treated.11 This trial was also notable in its improvement in manufacturing time for the CAR-T cells, with an average of 17 days between apheresis and return shipment from the manufacturer, which compares to a more typical average time of 28 days in previous CAR-T cell studies.11 Initial investigations of the application of CAR-T therapy in multiple myeloma (MM) have also used CD19-directed CAR-T, with one case series of 10 patients reporting achievement of a PR or very good partial response (VGPR) in 3 patients who remained free from progression at last follow-up (range 70–222 days). An additional 3 patients in the study were also progression-free, but not yet evaluable for response.12 The utility of CD19 CAR-T in MM remains to be determined, and additional studies are ongoing.
Cytokine release syndrome (CRS) and neurologic toxicity are the most well documented serious adverse events associated with CAR-T cell therapy and occur during in vivo cell expansion. CRS is characterized by fevers, hypotension, and other reversible associated toxicities, such as neurologic disturbances and respiratory dysfunction, and can be life-threatening.13 However, it has been noted that the occurrence, but not the severity, of CRS is correlated with response rates.4 Close monitoring, careful management, and use of anticytokine therapy have been used to control these toxicities and maintain both safety and efficacy.2 Tocilizumab, an interleukin-6 receptor antagonist, is most frequently used for management of grade 3–4 CRS and received FDA approval for this indication with the approval of tisagenlecleucel.1 It may be necessary for patients to receive multiple doses of tocilizumab for the treatment of CRS; however, if CRS is unresponsive to tocilizumab, steroids (dexamethasone or methylprednisolone) are typically initiated.14 Other agents that have been used in the second-line treatment of CRS include etanercept and siltuximab, but these have typically been used only in the setting of clinical trials because CRS can usually be effectively managed with tocilizumab and corticosteroids.14 Recent clinical trials of certain CAR-T constructs have also begun to incorporate administration of a prophylactic dose of tocilizumab 36 hours following CAR-T cell infusion in an effort to reduce the severity of CRS. Preliminary results from one of these trials reported a grade 3 or higher CRS incidence of 13%, compared to the incidence in previous trials ranging from 27% to 53%.11,13 In addition, other strategies related to cell dose, fractionated administration, thresholds for tumor burden at time of infusion, and incorporation of suicide genes or protein co-expression that can be targeted by commercial depleting antibodies continue to be tested in clinical trials in an effort to identify the safest mode of administration of this therapy.2
Other major limitations of CAR-T cells are lack of persistence in some patients, tumor evasion, and resistance. Despite the promising results of initial CD19 CAR-T trials, a subset of treated patients have relapsed with CD19-negative disease or with CD19-positive disease when CAR-T cell levels become undetectable.2 Strategies currently in clinical testing to overcome resistance include dual antigen targeting (e.g., CD19 and CD123) or antigen and chemokine co-expression, use of CAR-T cells engineered to no longer express immune checkpoint molecules such as programmed cell death protein/ligand 1 (PD1/PDL1), and the co-administration of CAR-T therapy and PD1 monoclonal antibodies.2 CAR-T cell persistence is highly variable, according to the target antigen, the costimulatory domain, and cell culture systems and manufacturing processes used.2 CAR-T cell persistence is not the only correlate of durable efficacy, and optimal persistence duration remains an area of active investigation; novel constructs are continuing to be developed to improve this aspect of the therapy.2,13
CAR-T target selection has quickly evolved into the proverbial space race of cancer immunotherapy. Current targets under investigation in hematologic malignancies include CD20, CD22, and CD30 for B-cell malignancies; CD33 and CD123 for myeloid malignancies; and CD138, immunoglobulin-κ light chains, and B-cell maturation antigen (BCMA) for MM in hopes of improving both efficacy and disease specificity.2,13 Encouraging preliminary data of BCMA-directed CAR-T in MM was recently reported, with 33 out of 35 relapsed or refractory patients enrolled in a phase-1 trial demonstrating a clinical remission (CR or VGPR) within 2 months of infusion.15 Furthermore, 19 of these patients have been followed for more than 4 months, 14 of which have achieved a stringent CR (sCR) without a single case of relapse.15 Five of these patients have been followed for more than 1 year and remain in sCR and free of minimal residual disease.15 CAR-T therapy is also beginning to penetrate the world of solid tumors; clinical trials are either currently under way or planned using the following targets: human epidermal growth factor receptor 2 in sarcoma and glioblastoma multiforme, interleukin 13 receptor-α in glioma, disialoganglioside GD2 in neuroblastoma, and carcinoembryonic antigen in lung, breast, colorectal, and gastric cancers.2,13 Solid tumor application of CAR-T cells will pose unique challenges because these targets are often not expressed uniformly on tumor cells as they are in hematologic malignancies and will likely result in further enhancements in the engineering of this therapy.2
A discussion of CAR-T therapy without mention of cost would unfortunately be incomplete. Cost has emerged as a primary concern with the approval of tisagenlecleucel and its associated $475,000 price tag.16 The product’s manufacturer, Novartis, has struck a first-of-its-kind pay-for-performance deal with the Centers for Medicare and Medicaid Services that will fully reimburse the cost of therapy in the event that no response is seen by 1 month after infusion; however, questions and debates regarding reimbursement and pricing still abound.17 The manufacturer is also providing copay and travel assistance programs, given that the therapy will not be immediately available at all centers.17 Regulation and practical administration for CAR-T therapy is also uncharted territory because, despite being an engineered human cell product, it is being regulated by the FDA as a drug. This situation will likely create novel challenges for pharmacy departments, with unique considerations related to product labeling and dispensing, budgeting, risk evaluation and mitigation strategies (REMS) program management, and reimbursement. Little guidance is available on these issues, though many institutions are currently navigating their way through them and may be able to share their experiences in the future. The Foundation for the Accreditation of Cellular Therapy (FACT) has created the first set of accreditation standards for programs administering immune effector cell therapy; they provide guidelines and minimum requirements for appropriate management of these therapies from an institutional perspective and are an excellent resource for institutions that will provide this therapy.18 Creation of standard operating procedures for monitoring and management of toxicities and educational and training requirements of key personnel, including pharmacists, are among the outlined requirements set forth by FACT, and these, when complete, will fulfill the majority of requirements of the tisagenlecleucel REMS program.18 We are seeing just the tip of the iceberg of CAR-T therapy, and as the technology improves and is used more widely, further questions and challenges will undoubtedly arise. However, for the present, we should all revel in this unique and exciting breakthrough in the war against cancer and all the potential it holds.

USP <800>: Strategies for Implementing a Successful Assessment of Risk
Sarah Newman, PharmD BCPS
Pediatric Clinical Hospital Pharmacist
Holtz Children’s Hospital—Jackson Health System
Miami, FL
The United States Pharmacopeia (USP) issued General Chapter <800> in February 2016, and institutions that prepare and administer hazardous drugs are expected to be compliant with the guidelines by July 2018.1 As this issue of HOPA News was being prepared, USP released a notice of intent to change the official date of USP <800> to December 1, 2019.2 This date will align with the next revision of USP <797>. However, USP is still encouraging “early adoption and implementation of Chapter <800> to help ensure a safe environment and protection of healthcare practitioners.”2 Although each state board of pharmacy may require slight variations on USP <800>, the general requirements of the chapter will remain the same, with regard to safe handling of hazardous medications, for all institutions.
USP <800> provides specific guidance for those medications categorized as hazardous by the National Institute for Occupational Safety and Health (NIOSH). NIOSH defines a hazardous drug as a medication that has one of these six characteristics:3
carcinogenicity
teratogenicity
reproductive toxicity in humans
organ toxicity in low levels in animals or humans
genotoxicity
mimicking of a hazardous drug in structure or toxicity.
NIOSH further categorizes hazardous medications (see Tables 1, 2, and 3 in NIOSH’s 2016 publication).3 Table 1 includes those antineoplastic agents that pharmacists have traditionally viewed as hazardous, with long-standing handling precautions already in place. Agents listed in Tables 2 and 3, on the other hand, may include many drugs for which pharmacists have not implemented strict handling requirements, but all of which now require documented containment strategies under USP <800>.
Under the new USP <800>, many institutions are being challenged to rethink the safety of drugs and dispensing procedures that historically have not required the same stringent containment strategies as the antineoplastic drugs in Table 1. Institutions have two options. The first is to handle each NIOSH drug using all the containment and risk practices listed in USP <800>, a proposition that is likely to affect pharmacy workflow too adversely to be a practical or feasible solution. The second is to perform an assessment of risk to determine alternative containment strategies and work practices. This allows some dosage forms of hazardous drugs to be handled without all of the containment precautions outlined in USP <800>.1 Most institutions are electing to follow this second option.
When the assessment of risk is completed for all hazardous drugs on an institution’s formulary, engineering controls, personal protective equipment, and workplace practices must be reviewed to ensure appropriate hazardous drug control per USP <800>.1 Such a succinct summary may make the process sound easy, but depending on the number of hazardous NIOSH medications on an institution’s formulary, the reality is that the assessment of risk is a large undertaking, leaving staff at some institutions wondering where to start.
Faced with this conundrum, the Department of Pharmacy at Cincinnati Children’s Hospital Medical Center recently spearheaded a Children’s Hospital Association collaborative effort between member institutions to complete an assessment of risk for each of the hazardous drugs listed in NIOSH Tables 2 and 3. When asked for some general tips on completing the assessment of risk, Chad Watkins, PharmD, director of pharmacy for Cincinnati Children’s Hospital Medical Center–Liberty Campus, recommended first prioritizing those medications that pose the highest risk to healthcare workers and work down the list toward medications that pose minimal risk.4
Watkins further advocates “establishing several levels of risk to group NIOSH Table 2 and 3 medications [into], such as: Low Risk, Moderate Risk, and High Risk.”4 In deciding what constitutes low, moderate, or high risk, Watkins recommends establishing criteria that would necessitate an increase in risk category, such as manufacturer’s safe handling guidelines, carcinogenicity as defined by the International Agency for Research on Cancer, American Hospital Formulary Service classification, pregnancy category, and chemical characteristics.3
Risk factors for exposure to certain hazardous drugs may vary between institutions and will affect whether a drug is categorized as low, medium, or high risk. For example, opening a unit-dose package of a hazardous drug prior to administration poses a lower risk of exposure than crushing a tablet to create a suspension.5 An institution that purchases and dispenses tacrolimus only in unit-dose capsules may categorize risk exposure for tacrolimus as lower risk than a facility that purchases tacrolimus capsules in bulk bottles, which necessitates repackaging prior to dispensing. The risk category for tacrolimus would be even higher in a facility where staff members open those capsules to make an oral suspension. Consider the dosage forms and the life cycle of a drug in your institution when completing the assessment of risk.5 These assigned risk levels will help determine the management of handling and containment precautions under USP <800>.
When the drugs and risk levels have been determined, a standardized worksheet can be used to document the assessment of risk. This worksheet should include, at a minimum, the drug name, the hazardous-drug category, dosage forms, the risk of exposure, packaging, any required manipulation, and documentation of any alternative containment strategies or work practices. Review of this assessment of risk must be documented annually.1 A worksheet that can be tailored to meet your institution’s needs is available in a hazardous drug toolkit published by Joint Commission Resources.5
Following completion of the assessment of risk, institutions will need to review their personal protective equipment (PPE) to ensure that it meets the minimum standards outlined in the assessment of risk. NIOSH Table 5 and Section 7 of the USP <800> outline recommend PPE for healthcare workers.1,2 NIOSH has also published a detailed paper regarding appropriate PPE for the handling of hazardous drugs.6 Additionally, institutional policies will likely need to be reviewed, a process that Watkins says “poses a huge challenge in maintaining consistency between all hospital services.”4 Finally, all frontline staff must be educated on USP <800> process changes. According to Watkins, this is likely to be the biggest challenge in implementing USP <800>: “Developing a hazardous communication program that effectively reflects the process is essential in achieving compliance. The program must have the capability to direct handling precautions to all staff.”4 Because staff in several service areas will need to comply with USP <800>, training must be specific to each role and completed before staff members handle any hazardous drugs.1 Some strategies that may be implemented include required orientation on USP <800> practices for new hires, completion of annual competencies by frontline staff, and department-specific training courses. Per USP <800>, reassessment must be completed and documented at least once per year.2
Given that implementation of USP <800> will affect several institutional service lines, multidisciplinary involvement in completing the assessment of risk is essential. Watkins recommends that, at a minimum, the task force should include a compounding pharmacist, pharmacy manager/director, nursing manager/director, and staff from pharmacy education, nursing education, occupational safety, and employee health.4 This multidisciplinary approach to the assessment of risk allows each discipline to provide input based on where in the medication administration process their handling of hazardous drugs occurs. Gathering this information early in the assessment of risk process will allow for identification of potential issues in hazardous-drug handling prior to the transition to implementing USP <800> practices.
Implementing USP <800> will be a work in progress. As institutions complete this massive undertaking, lessons learned will likely necessitate reassessment and changes. Beginning with a focused plan for the assessment of risk, building strong training programs, and including key stakeholders early in the process will help to ensure a smooth rollout.

Is It Business-Savvy for a Pharmacist to Complete an MBA?
Marco Martino, PharmD MBA BCOP BCPS
Team Lead for Operations
Robert H. Lurie Comprehensive Cancer Center of Northwestern University
Chicago, IL
It is humbling and gratifying to serve the patients at the Robert H. Lurie Comprehensive Cancer Center of Northwestern University, a National Comprehensive Cancer Network–designated institution. The spectrum of patients seen at Northwestern Medicine ranges from those with early-stage cancers requiring standard-of-care antineoplastic regimens to those with advanced cancers requiring personalized medicine. Running this vast cancer center requires highly qualified employees across a range of interdisciplinary professions, including financial professionals, physicians, nurses, and pharmacists. My role as the team lead for the operations of our three clinic pharmacies requires me to be more on the front line, handling daily operations, than my colleagues in the coordinator and manager roles, who serve primarily on the back end, tackling higher-level projects. My pursuit of a master’s degree in business administration (MBA) with a healthcare focus has opened the door for me to effectively operationalize the work of clinic pharmacies, manage personnel, and become a steward of inventory and resources.
By way of an introduction, after being out of school for 2 years, I started to steer from oncology to emergency medicine, acute and critical care, and outpatient oncology. I knew that to be the oncology pharmacist I aspired to be, I needed to augment my clinical and managerial skills. Rather than completing a PGY-2 oncology or health-system administration residency, I turned my attention to finding an MBA program with a healthcare focus. This program took me on quite a journey—starting with a course on critical thinking, continuing with courses on accounting and finance and then managerial and personnel behavior, and concluding with courses on the healthcare delivery system, healthcare ethics, and healthcare financing.
Whereas hands-on experience and immersion provide very potent and effective learning opportunities, the completion of my MBA degree with a healthcare focus led me to my current position, where I am able to apply the vast majority of my didactic work in my job. For example, the course I took on applied statistics covered a wide array of ways to quantify and apply statistics to real-world situations. This course assisted me in understanding medical journals, particularly the sections on statistics and quantification of results. It also helped me understand how institutions report quantitative results about performance, whether on an individual, departmental, or institutional level. Another course that has had an impact on my career focused on managerial and personnel behavior. All the institutions I have worked in have differed in managerial style and reporting structure, which is not surprising. I received intensive training in this course, but I found that no didactic coursework can truly train and prepare one for handling success and conflict. However, because the course immersed us in many case studies, the real-world examples of success and conflict that I encounter at work are not completely foreign to me.
Two other courses that have paid major dividends in my current role are those on healthcare ethics and healthcare financing. Both courses offered numerous parallels in health care, especially oncology. We dove into the complex topic of medication pricing, which I then applied to oncology. Although we know the amount of research and development that goes into creating medications, the expense of antineoplastic medications presents an obvious ethical dilemma, particularly when we are working with such a vulnerable patient population. On a more objective note, I have found that knowledge of inventory management is imperative in oncology. Outpatient oncology clinic pharmacies operate with a vast budget—in some cases a budget larger than those of entire pharmacy departments. It is therefore crucial that we evaluate our inventory turnover so that we can establish appropriate par levels for both medications and ancillary supplies. We want to do what is right for our patients by having the proper medications on hand, but we also want to do what is right for our department by ensuring that our inventory is turning over appropriately.
My completion of an MBA with a healthcare focus has had a significant impact on my career, allowing me to gain the experience and immersion that I needed to apply my education to my work. However, despite the advantages I have gained by completing an MBA, I see that pharmacists with MBAs are still relatively uncommon. For pharmacists who will not be completing a PGY-2 oncology or health-system administration residency but would like to pursue pharmacy management, augment their supervisory skills, or better understand and apply the complex finances that surround oncology pharmacy, I recommend pursuit of an MBA.

The concept of using the host’s immune system in the fight against cancer surfaced in the 19th century.1,2 Historically, however, limited strides have been made in stimulating T-cell immune responses via vaccination or cytokine treatment (interleukin-2 or interferon-alpha).1-5 Recently, cancer immunotherapy has reemerged in the forefront of oncology investigation, leading to a surge of immune modulation agents approved by the U.S. Food and Drug Administration (FDA).6-10 The resurgence in oncology care resulted from an investigative shift in targeting tumor immune inhibitory mechanisms, with the identification of key immune checkpoint receptors, cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed cell death-1 (PD-1).1-5
Since 2014, five monoclonal antibodies (mAbs) that target the immune checkpoint PD-1 pathway have been approved by the FDA.4-8 These agents have shown rapid growth in approval accompanied by a vast array of solid tumor indications. Further breakthroughs with these agents are expected, given the substantial number of trials recruiting subjects (a clinicaltrials.gov search for “PD-1” revealed 236 recruiting studies, and a “PD-L1” search showed 166 recruiting studies).11-12 PD-1 and its respective ligands, programmed cell death ligand-1 (PD-L1) and programmed cell death ligand-2 (PD-L2), when bound cause T-cell exhaustion.1-5 Tumor cells have an upregulation of PD-L1, allowing these cells to suppress the immune system and avoid elimination. Blocking PD-1/PD-L1 via PD-1 or PD-L1 mAbs allows for T-cell activation. Pembrolizumab, an IgG4 PD-1 mAb, is among these agents.
On May 23, 2017, pembrolizumab achieved a milestone in oncology care when it obtained accelerated FDA approval for a biomarker-specific indication regardless of tumor site origin.6,13 The tissue-/site-agnostic indication is for the treatment of microsatellite instability–high (MSI-H) or deficient mismatch repair (dMMR) adult and pediatric patients with unresectable or metastatic solid tumors. Patients with solid tumors must have had disease progression following prior treatment and have no satisfactory alternative treatment options; metastatic colorectal cancer (mCRC) patients, specifically, are candidates for pembrolizumab only after disease progression on fluoropyrimidine, oxaliplatin, and irinotecan. The accelerated approval was based on tumor response and the duration of response seen in a pooled analysis, with continued approval contingent upon a confirmatory trial. The prescribing information limits use in pediatric patients with MSI-H central nervous system cancers because safety and efficacy in this population have not been established. Dosing is 200 mg flat dose (adults) or 2 mg/kg (pediatric patients) intravenous (IV) every 3 weeks.
Microsatellites are repetitive sequences of deoxyribonucleic acid (DNA) susceptible to errors during replication.14-16 The mismatch repair system functions to correct these insertion or deletion errors; however, when a deficient mismatch repair system is present, this leads to microsatellite instability and causes a highly mutated state. MSI-H tumors can be sporadic or can be associated with hereditary nonpolyposis colorectal cancer (HNPCC), known commonly as Lynch syndrome. Lynch syndrome is characterized by inherited defects in MMR proteins (MLH1, MSH2, MSH6, PMS2).14-17 MSI-H tumors are seen more in the sporadic setting resulting from somatic hypermethylation of the MLH1 promotor (often associated with BRAFV600E mutation in mCRC). MSI-H/dMMR status is tested either by polymerase chain reaction (PCR) DNA testing or via immunohistochemical (IHC) staining to detect the loss of one or more of the mismatch repair proteins.14-16 A variety of malignancies are associated with MSI-H. Colorectal cancer (15%–20%), endometrial cancer (20%–30%), and gastric cancer (8%–22%) are more frequently reported, but this tumor phenotype can be seen to a lesser degree in many malignancies, including cholangiocarcinoma, pancreatic, esophageal, prostate, small-bowel, thyroid, melanoma, ovarian, cervical, head and neck, and renal cell carcinoma.14
Differences between CRC MSI-H/dMMR tumors and microsatellite stable/proficient mismatch repair (MSS/pMMR) CRC tumors have emerged—in clinicopathological features, prediction of immunotherapy response, and prognoses.18-19 National guidelines recommend MSI or MMR testing for all mCRC patients, given the clear distinction in responses shown with immunotherapy in these two subsets.18 The immunotherapy response differences in mCRC were identified by two phase-2 studies with PD-1 inhibitors. Le and colleagues revealed an objective response rate (ORR) of 40%, with 78% progression-free survival (PFS) rate at 12 weeks in the MSI-H/dMMR group who received pembrolizumab compared to 0% ORR and 11% PFS rate in the MSS/pMMR group.20 Updated results continue to show benefit in only MSI-H/dMMR mCRC patients, with ORR of 50% compared to 0% in the MSS/pMMR group.21 Disease control was 89% for MSI-H/dMMR mCRC compared to 16% in the MSS/pMMR group. Overman and colleagues studied nivolumab alone or in combination with ipilimumab (a CTLA-4 inhibitor). Preliminary results showed that nivolumab alone resulted in a 27% versus 0% ORR in MSI-H/dMMR and MSS/pMMR, respectively.22 A recent update on the current results of the nivolumab-alone arm in the MSI-H/dMMR mCRC group showed a 31% ORR and 69% disease control.23 Diaz and colleagues reported the results of MSI-H/dMMR non-CRC patients from a phase-2 independent tumor histology trial design.24 Twenty-nine patients (with mostly endometrial, pancreatic, and ampullary cancer) received pembrolizumab. The ORR was 48%, with a disease control rate of 72%. Median overall survival and PFS were not reached at 21 months.
Pembrolizumab’s recent tissue-/site-agnostic approval was based on a pooled analysis of five uncontrolled open-label multicenter single-arm trials (KEYNOTE-016, KEYNOTE-164, KEYNOTE-028, KEYNOTE-012, and KEYNOTE-158).6 Trial design and patient population information is included in (Table 1 – see PDF). There were 149 total MSI-H/dMMR patients with a median age of 55 years. Patients had an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. Almost all patients (98%) had metastatic disease. Patients had a median of two prior treatments. Sixty percent had mCRC, with the remainder involving a variety of non-CRC tumors (Table 2 – see PDF). MSI or MMR status was determined via local PCR, local IHC, or central PCR. Patients received either 200 mg IV pembrolizumab every 3 weeks or 10 mg/kg IV every 2 weeks. From the pooled analysis the ORR was 39.6% (majority partial response 32.2%), with a duration of response at 6 months of 78%. The rationale for the positive outcomes in MSI-H/dMMR subset compared to MSS/pMMR patients is the concept that MSI-H/dMMR status contains a hypermutated state, increased tumor neoantigens (non-self-recognition by the immune system), and tumor-infiltrating T-cell lymphocytes making MSI-H/dMMR tumors more susceptible to immunotherapy modulating agents.
Pembrolizumab’s approval for a tissue-agnostic indication represents an exciting step in oncology care, particularly for rare tumors or entities, which often lack investigational focus and standard-of-care treatment options. MSI-H/dMMR is a rare entity among malignancies. MSI and MMR testing requires tissue; therefore, status determination may present a dilemma for additional testing in rare tumors with a low incidence of MSI-H/dMMR. Regardless of additional testing or biopsy, this pooled analysis allowed for outcomes to be reviewed faster than in traditional tissue-specific trials and was evaluated in patients with refractory cancer who had limited treatment options. Careful considerations and challenges remain, however, in expanding approvals or trial designs based on a targeted characteristic. There remain nonresponders to PD-1 inhibitor monotherapy in MSI-H/dMMR (responses ~ 30%–50%). Future investigation in this tissue-agnostic subset presents a challenge when one is considering immunotherapy-refractory disease and combination therapy trial design because antineoplastics differ in effectiveness across malignancies. Further, oncology investigators must be cautious when extrapolating targeted characteristics across malignancies, as is evident in the study of BRAF inhibition. BRAF inhibitor outcomes were shown to be vastly different among varying BRAF mutated tumors (minimal response in mCRC compared to metastatic melanoma). Targeted therapy and molecular tumor characterization have greatly expanded the way we understand the heterogeneous nature of cancer; however, more steps remain in understanding these targets across malignancies and even in tumor types with the same origin.

Collaborative Drug Therapy Management in the Oncology Setting

Collaborative practice agreements (CPAs) allow pharmacists to contribute toward a team-based healthcare model, as well as improve medication safety and achieve cost savings.1,2 The concept of collaborative drug therapy management (CDTM) is not new: the first position statement on the topic was issued by the American College of Clinical Pharmacy in 1997.3 As the projected shortage of oncologists increases each year, the need for CDTM agreements grows. A 2014 study published by the American Society of Clinical Oncology projects that by the year 2025, about 2,400 fewer oncologists may be practicing than are needed.4 As the projected shortage of healthcare providers, and specifically oncologists, increases, pharmacists are in a position to help improve access to healthcare in the oncology setting.5
Although CDTM is not universally permitted, 48 states currently have laws and regulations in place allowing its implementation. The pharmacy services that are allowed under CPAs vary by state and may include such functions as modifying medication therapy, initiating and discontinuing medication therapy, and ordering and interpreting laboratory studies. Although CDTM agreements traditionally exist between pharmacists and physicians, a number of states have allowed CDTM agreements to expand and include other healthcare providers such as nurse practitioners. The scope of practice of the collaborating pharmacist also will vary depending on each state’s laws and regulations. Many states allow the pharmacist to make patient-care interventions according to preselected protocols and guidelines or for specific drug classes or drugs. Some states, however, allow the pharmacist to make patient-care interventions without the use of protocols, providing a more autonomous scope of practice.6
Much of the literature on CPAs that has been published to date has focused on chronic disease states, with numerous studies showing clinical benefits in such disease states as diabetes, hypertension, and hyperlipidemia.7,8 Currently, limited data are available to document the clinical or economic benefits of CDTM in the oncology setting. Hansen and colleagues reported the outcomes of CDTM agreements for the management of chemotherapy-related symptom management in a gynecologic oncology clinic. The CDTM agreements contained treatment algorithms for the management of chemotherapy-induced nausea and vomiting, chemotherapy-induced peripheral neuropathy, vasomotor symptoms, vaginal dryness, and bone health. This CDTM pilot study showed favorable results in patient and physician satisfaction surveys, as well as improvements in patient symptom scores compared to baseline.9 Valgus and colleagues described the implementation of a pharmacist-led interdisciplinary care model in an outpatient oncology clinic serving gynecologic, radiation, medical, and surgical oncology patients. The majority of medication interventions pertained to pain management, with the other symptoms commonly managed consisting of nausea and vomiting, constipation, and anxiety. Reductions in patient-reported symptoms were seen after the first visit, and reductions were sustained over an average of three visits.10
Though numerous studies of the clinical outcomes associated with CPAs have been conducted, some studies have detailed their economic benefits. Schumock and colleagues conducted a systematic literature review of articles that evaluated the economic impact of clinical pharmacy services. This review identified pharmacy interventions in a wide range of clinical settings, including government clinics, hospital-associated clinics, community hospitals, university hospitals, and physicians’ offices. A mean benefit-to-cost ratio of 4.68 to 1 was shown with the addition of clinical pharmacy services.2 The financial impact of clinical pharmacy services was also reported by Lee and colleagues in a study that evaluated the economic impact of pharmacists’ recommendations.11 This review evaluated 600 medication recommendations by pharmacists in a variety of settings, including inpatient and outpatient facilities and nursing homes. A total of 1,511 recommendations were made, with a physician acceptance rate of 92.4%. The mean medication cost avoidance was increased in the inpatient setting as compared to the outpatient setting or nursing homes, but the mean total medication cost avoidance was $420,155.11 Although the financial impact will vary depending on the practice setting and clinical scenario, this study shows that pharmacists’ interventions can lead to substantial cost savings. A Cochrane Database review of 25 studies showed that pharmacists’ collaborative practice resulted in a decrease in the overall use of drugs, as well as the cost.12 Despite the fact that studies have shown the positive effect of pharmacists’ interventions on healthcare costs, reimbursement and funding for these services are limited. Without adequate compensation, the implementation of CDTM may be severely limited, and this limit may be a barrier to optimizing healthcare outcomes.1
The documentation of pharmacy services is an important component of CDTM and can help further the development of collaborative agreements. Although not all states have laws and regulations requiring documentation of pharmacists’ activities, many require that pharmacists record and track interventions and that collaborating prescribers review these documents at routine intervals.4 The documentation of activities can allow collaborating prescribers to monitor and approve of interventions, but it also allows tracking to be used for financial and research purposes. Future research supporting the financial and clinical impact of CDTM on the healthcare system will require thorough records and evaluation of pharmacists’ interventions. These documents may be in the form of electronic medical records or in a format tailored to the practice setting and CPA. A study by Sledge and colleagues reported on the use of a daily pharmacy progress note in the surgical intensive care unit. In a 2-month period, 462 daily pharmacy progress notes resulted in 1,055 therapy changes and the avoidance of one sentinel event.13 This study showed that the documentation of pharmacy services not only provides evidence of the pharmacist’s involvement in the multidisciplinary team but also improves patient outcomes.
Despite the many proven benefits of CDTM, many providers are hesitant to sign a CPA. Many reasons for this concern exist, such as not understanding the pharmacist’s credentialing, experience level, or scope of practice.6 Thus, it is important that the pharmacist has established a trustworthy relationship with the providers with whom they request entrance into a CPA. Snyder and colleagues reported on the importance of trustworthiness in the success of CDTM agreements in the community setting. It was shown that physicians scored pharmacists higher on a Pharmacist-Physician Collaborative Index when they had frequent face-to-face communications and when the pharmacist made consistent contributions that improved patient care.14 Also, healthcare providers who have a strong working relationship with a pharmacist are more likely to have success in improving clinical outcomes.
Although many states require pharmacists to possess specific education and training in order to participate in CPAs, physicians and other healthcare providers may not be familiar with pharmacists’ credentials. One way to alleviate this problem would be to educate the prescriber on the credentialing process for pharmacists and explain any experience the pharmacist may have within the given field of practice.
The development of CPAs between pharmacists and healthcare providers has been shown to improve clinical and economic outcomes, increase access to health care, and improve medication safety. Given the projected shortage of physicians, and specifically oncologists, pharmacists are in a position to improve oncology patients’ access to the healthcare system. Pharmacists should therefore work closely with their collaborating prescribers to develop trustworthy relationships and limit any potential barriers to CDTM implementation. Routine documentation of pharmacy activities can help demonstrate the clinical and financial impact of CDTM and may provide a basis for reimbursement for services in future healthcare models.

Evaluating Drug Interaction Databases: Results from an Exploratory Analysis
Katherine Saunders, PharmD
Ambulatory Oncology Clinical Pharmacy Specialist
AU Health
Augusta, GA
Patients are taking an increasing number of medications, including those used to treat cancer and those required for treating comorbidities. Patients and healthcare team members rely on oncology pharmacists to be experts on all these medications. An exciting aspect of oncology practice is the number of new oral antineoplastic (OA) agents coming to the market and the potential for new approvals for existing OAs. Given that many of these drugs may come to market under expedited review through the U.S. Food and Drug Administration (FDA), approval may be granted without a formal drug-drug interaction analysis. With the introduction of these drugs into practice comes a challenge for oncology pharmacists: how to best screen a patient’s medications for clinically relevant drug interactions when initiating an OA agent.
Dr. John B. Bossaer and Dr. Christan M. Thomas aimed to shed light on this clinical question through an exploratory evaluation of existing drug interaction databases, a common resource for clinicians. This research, titled “Drug Interaction Database Sensitivity with Oral Antineoplastics: An Exploratory Analysis,” was published in March 2017 in the Journal of Oncology Practice.1 Although these databases have been previously evaluated in regard to their sensitivity in detecting drug interactions, those studies did not include OAs. The research team selected 20 drug interactions encountered in actual clinical practice and deemed to be clinically relevant. Clinically relevant was defined as a drug interaction that would require a change in therapy, such as selection of a new drug, a change in dose, or more frequent monitoring. This definition is more liberal than those used in the past; however, the authors felt that it more accurately reflected real-world practice. These 20 interactions include a variety of types, as well as newer agents that lack formal drug interaction studies. Examples include the interaction between pazopanib and amiodarone, which results in an increased risk of QTc prolongation, and the interaction between idelalisib and rivaroxaban, which results in an increased risk of bleeding. Well-known interactions, such as that between capecitabine and warfarin, were also included. These 20 interactions were then processed through five electronic databases commonly encountered in clinical practice: four of these were designed for the healthcare professional (Epocrates, Facts & Comparisons, Lexi-Interact, and MicroMedex), and one was oriented toward patients and non–healthcare providers (Drugs.com). The distribution of sensitivity across groups was assessed using the Cochran Q test.
The authors report that the sensitivities for each database varied. MicroMedex was found to have a sensitivity of 70% (95% confidence interval [CI], .46–.87), Facts & Comparisons, 70% (CI, .46–.87), Epocrates, 90% (CI, .69–.98), Lexi-Interact, 95% (CI, .73–.99), and Drugs.com, 95% (CI, .73–.99). The difference in their detection of clinically significant drug interactions was statistically significant, with a pvalue of .016. In addition, classification of interactions (major, moderate, not detected, etc.) varied among the databases. Only three interactions (those between idelalisib and phenytoin, bosutinib and voriconazole, and ibrutinib and voriconazole) were classified the same across all five databases. Even if the interactions labeled as major or moderate were considered equivalent, the databases had an agreement rate of 45% (n= 9).
The authors state that these results are not intended to indicate the superiority of one database over another. On the contrary, the variability among the databases, both in detecting an interaction and classifying it, suggests to the researchers that clinicians should use at least two electronic databases when checking a drug interaction. Databases that are transparent in the analysis of a drug interaction (for instance, including links to data supporting the interaction) are preferred. The authors also discuss the need for obtaining a detailed medication history from the patient during clinical encounters rather than relying on a medication list reported in the electronic medical record.
The authors also discuss areas for future research and initiatives and highlight the need for standardization in analysis of drug interactions. The authors note the lack of criteria for defining drug interactions with OAs, which likely contributes to the variability seen in these databases. Furthermore, this study omitted interactions not deemed clinically significant and therefore does not assess the specificity of these databases. Future endeavors that focus on specificity may address alert fatigue, a concern related to the extensive use of electronic resources by those working in the healthcare system. Theoretical drug interactions should also be included in these analyses because they may not come to light until several years after the drugs’ introduction into clinical practice.
This exploratory study shows the growing complexity of oral antineoplastics. Clinicians are faced with new agents for which formal drug-drug interaction studies may be lacking. In addition, patients are taking an increasing number of medications for other chronic diseases, and these medications are often prescribed by other providers. Given the high cost and insurance restrictions associated with OAs, patients may be using specialty pharmacies in addition to their preferred local pharmacy, making it difficult for pharmacists to conduct an accurate drug utilization review. Finally, although these databases have the potential to identify many of the clinically relevant drug interactions, the decision about what action to take is patient-specific and is driven by many factors. The work of Dr. Bossaer and Dr. Thomas examining the usefulness of these drug databases in detecting drug-drug interactions, as well as the potential shortcomings of these databases, highlights the need for the clinical expertise of an oncology pharmacist as a member of a patient’s cancer care team.

Highlights of HOPA’s 2017 Practice Management Program (September 15–16)
Lindsey Amerine, PharmD MS BCPS
Assistant Director of Pharmacy
UNC Medical Center
Chapel Hill, NC
HOPA’s 5th annual Practice Management Program (PMP) was held September 15–16, 2017, in Chicago, IL. The Windy City blew in excellent presenters and an engaged audience for the 2-day conference. Session topics ranged from oncology financial management and oncology care models to intravenous (IV) automation and technology.
A preconference that focused on investigational drug services (IDSs) was held on September 15. Christopher Lowe, PharmD BCPS, spoke about a centralized IDS for each of his health system’s entities. Kathy Galus, PharmD BCOP, highlighted the role of clinical pharmacists within the IDS and showed how a proactive approach to services can benefit the research community. Sapna Amin, PharmD BCOP, described the recommendations for IDS best practices made by HOPA and the Association of Dedicated Cancer Centers. Each presentation raised thought-provoking questions and stimulated lively discussion among the attendees.
The conference began with opening remarks from HOPA’s president, Susannah Koontz, PharmD BCOP FHOPA. Prior to the keynote address, she introduced a surprise award renaming HOPA’s PMP keynote lecture the Niesha L. Griffith Keynote Lecture. Koontz presented a plaque to Niesha Griffith, MS RPh FASHP, vice president of cancer services at West Virginia University Health System. Griffith then introduced the inaugural Niesha L. Griffith Keynote Lecturer, William (Bill) McGivney, PhD, managing principal at McGivney Global Advisors and former CEO of the National Comprehensive Cancer Network.
McGivney spoke about the evolving needs and direction of cancer care and called on HOPA to continue to set the direction for cancer care delivery and take a leadership role in that arena. He commended HOPA’s strategic plan as a sturdy framework for these efforts, similar to the path followed by the NCCN in solidifying its place as a leader in cancer care.
The remainder of Friday’s sessions centered on oncology care models, white bagging/brown bagging solutions, and oral chemotherapy. Each presentation provided not only excellent information but also practical solutions and examples to help audience members within their own practice sites. The Saturday morning sessions covered a wide array of topics: productivity models, budgeting and managing oncology financials, implementation of USP <800>, and IV technology and automation.

The Use of Bevacizumab in Treating Cervical Cancer

The American Cancer Society estimates that about 12,820 new cases of invasive cervical cancer will be diagnosed and about 4,210 women will die from cervical cancer in the United States in 2017.1 Despite primary prevention measures such as screening and human papillomavirus (HPV) vaccination, cervical cancer remains one of the most common cancers in women and is often diagnosed at advanced stages. Women with recurrent and metastatic cervical cancer have historically had extremely limited treatment options.2
It has been the standard of care since 1999 to consider the combination of chemotherapy and radiation for treating stages IB2 to IVA cervical cancer.3 However, the long-term complications from radiotherapy and poor control of micrometastases raised interest in investigating other approaches. Single-agent cisplatin was widely accepted as the standard for treating late-stage cervical cancer until 2005, when Long and colleagues demonstrated improved overall survival (OS) in patients treated with doublet chemotherapy versus cisplatin alone.4
In 2009, the Gynecologic Oncology Group (GOG) 204 study examined four cisplatin-based doublets to assess their efficacy and toxicities. This study found a trend favoring the cisplatin/paclitaxel regimen, although it was not statistically significant. Henceforward, cisplatin and paclitaxel has been considered the standard regimen for patients with stage IVB, recurrent, or persistent cervical carcinoma. However, the investigators in this study concluded that alternative regimens are reasonable and should be considered for individual patients, especially in the setting of pre-existing comorbidities or toxicities.5 Many patients unfortunately develop recurrence within the first 2 years of completing treatment, and their cases are often not salvageable. Survival for metastatic, recurrent, or persistent cervical cancer is about 12 months.2
Vascular endothelial growth factor (VEGF) has emerged as a target to inhibit angiogenesis in many solid tumors because the dysregulation of angiogenesis plays a role in tumor growth and metastasis. Vascularization and increased microvessel density are typically seen on colposcopy in women with invasive cervical cancer; thus, the VEGF receptor seemed a compelling potential target.6 Bevacizumab is a recombinant humanized monoclonal antibody that binds to VEGF A with potent anti-angiogenic action, and it has been approved for use in treating several types of solid tumors.7 In 2006, Wright and colleagues conducted a case series that suggested activity of bevacizumab in recurrent cervical cancer, demonstrating a progression-free survival (PFS) extended by 4.6 months.8 A subsequent phase-2 trial evaluated bevacizumab in patients with persistent or recurrent cervical cancer. This study found that median PFS was extended by 3.4 months and overall survival (OS) by 7.3 months, which compared favorably to historical data. As expected, hypertension, thromboembolism, anemia, cardiovascular side effects, vaginal bleeding, neutropenia, and gastrointestinal fistulas were identified as toxicities, but overall the treatment was considered to be well tolerated.9 This phase-2 study prompted the development of a phase-3 study with bevacizumab.
GOG 240 was a randomized, open-label phase-3 trial that included patients with metastatic, persistent, or recurrent cervical carcinoma.10 It included patients with an Eastern Cooperative Oncology Group performance status of 0 or 1 and otherwise healthy patients with a very poor prognosis. Four hundred fifty-two patients were randomly assigned to treatment with either cisplatin plus paclitaxel, with or without bevacizumab, or the non-platinum-containing regimen paclitaxel plus topotecan, with or without bevacizumab. This trial sought to answer two questions: (1) whether bevacizumab was effective in addition to chemotherapy, and (2) whether the non-platinum-based chemotherapy doublet of topotecan/paclitaxel would be effective in circumventing platinum resistance. An interim analysis in 2014 demonstrated no difference in outcomes between the platinum and non-platinum chemotherapy regimens. However, adding bevacizumab to chemotherapy significantly prolonged OS (3.7 months) and PFS (2.3 months) and improved the overall response rate (48% vs. 36%).10 Primarily on the basis of this interim analysis, the FDA approved bevacizumab for women with advanced cervical cancer. This was the first new drug approved for the treatment of cervical cancer in more than 8 years. In addition to FDA approval, these results also led to the National Comprehensive Cancer Network guidelines listing of bevacizumab as a category 1 recommendation for patients with recurrent or metastatic cervical cancer in combination with either cisplatin/paclitaxel or topotecan/paclitaxel.11
In July 2017, the final results from the GOG 240 trial were published. The overall survival curves showed stable separation with a 3.5-month improvement when bevacizumab was added to chemotherapy (16.8 months vs. 13.3 months, p = .007). Although this improvement may appear modest, it should be considered that most patients survive only about 12 months at this stage of disease. When the different chemotherapy arms (with and without bevacizumab) were compared, topotecan/paclitaxel was associated with a higher risk of disease progression over cisplatin/paclitaxel (median PFS 5.7 months vs. 7.6 months, p= .008), but there was no significant effect on OS (12.5 vs. 15 months, p= .88). Adding bevacizumab to the cisplatin/paclitaxel regimen reduced the hazard of death (OS 17.5 months vs. 15.0 months, p= .04), but this did not reach significance when added to topotecan/paclitaxel (16.2 vs. 12.0 months, p= .15). Interestingly, however, complete and partial responses to topotecan/paclitaxel were almost doubled when bevacizumab was added to the regimen (48% vs. 25%, p=.0004), an effect not seen with cisplatin/paclitaxel. Substituting topotecan for cisplatin did not circumvent drug resistance to platinum, which may suggest that cervical cancer does not exhibit platinum resistance specifically but instead may be resistant to chemotherapy in general. Using topotecan as a non-platinum-based alternative may be advantageous in patients with platinum hypersensitivity or renal insufficiency. After bevacizumab was discontinued, the researchers did not observe a negative rebound effect (i.e., a survival shorter after bevacizumab is stopped than after chemotherapy alone is stopped), which has been observed in other cancers.10
Across the literature, bevacizumab is associated with toxicities like hypertension (5%–18%), surgical and wound healing complications (3%–15%), gastrointestinal fistulas (2%–15%), thrombotic events (2.3%–10.6%), gastrointestinal perforation (.3%–3.2%), and nephrotic syndrome (less than 1%).12 Of these, fistula formation, which occurred in 15% of all bevacizumab-assigned patients in GOG 240, is one of the most concerning toxicities. A clinically significant fistula (grade 3, requiring intervention) occurred in 6% (n= 13) of patients receiving bevacizumab, versus less than 1% (n= 1) in the chemotherapy-alone group.10 Of note, all patients were previously irradiated. Recurrent or persistent disease in the pelvis following chemoradiation appears to be a risk factor for fistula formation, potentially due to the damage incurred to the microvasculature.13
GOG 240 also developed a set of prognostic factors known as the Moore criteria, which identify negative prognostic risk factors that may be used to help guide therapy. Negative prognostic factors included African American race, performance status 1, pelvic disease, prior treatment with cisplatin, and a progression-free interval less than 365 days. Risk categories included low-risk (0–1 factors), mid-risk (2–3 factors), and high-risk (4–5 factors). Patients in the high-risk group obtain the greatest benefit from bevacizumab (hazard ratio [HR] .536) compared to patients in the mid-risk (HR .673) or low-risk (HR .96) groups. Additionally, in low-risk patients treated with chemoradiation prior to recurrence, these criteria can be used to argue against including bevacizumab because the fistula risk is 8.6% with a very small survival benefit.13
GOG has now completed nine phase-3 randomized trials over 30 years in the cervical cancer patient population. Although considerable progress has been made, the challenge remains to find tolerable treatments that can further increase survival. Bevacizumab increases the survival of patients with advanced cervical cancer, but significant progress must still be made to cure patients of this devastating disease.

The Transition from PGY-1 to PGY-2
Ying Long, PharmD
PGY-2 Oncology Pharmacy Resident
Massachusetts General Hospital
Boston, MA
Traveling on a red-eye flight during my move from Los Angeles to Boston was exhilarating. Seventy-two hours after I waved goodbye to my PGY-1 residency, I was sitting in the new-employee orientation at Massachusetts General Hospital (MGH) as a PGY-2 oncology resident. Even before I entered pharmacy school, I knew I wanted to pursue a PGY-2 residency in a specialty. When this moment arrived, I was filled with enthusiasm. I knew that the program at MGH would be rigorous and demanding, but I was thrilled to be able to devote a full year to oncology.
A structured orientation in both the pharmacy department and oncology pharmacy helps transition new residents to the new work environment. Along with all the other incoming PGY-1 and PGY-2 residents, I started out my PGY-2 residency with a month of orientation in the MGH Graduate Pharmacy Education Program. In addition to the general hospital and pharmacy orientation, I had an orientation specifically for PGY-2 oncology residents, which included clinical training and assessments. A series of oncology pharmacology review sessions were also planned to help us build a solid foundation in chemotherapy and targeted therapies. I began shadowing pharmacists in both inpatient and outpatient oncology pharmacies early in the orientation, which helped me learn the oncology pharmacy workflow and provided me the opportunity to work with a number of pharmacists. I felt that this orientation setup helped transition me to the oncology pharmacy work environment.
One of the most important items on the PGY-2 oncology resident’s checklist is to communicate with the residency program director (RPD) about short-term and long-term goals. During the orientation month, I met with my RPD several times to develop a customized learning plan that would incorporate both the program’s goals and my personal goals. These goals and objectives were translated into specific activities, including clinical rotations, research, operation, leadership, education, and community services. I have found it very useful to have a goal-oriented plan that systematically guides me through the process.
Initially, I felt overwhelmed by the extensive list of activities under each of the objectives and goals set by the American Society of Health-System Pharmacists for completion during this year. Depending on the resident’s prior experiences, preceptors or the RPD may need to allocate more time to areas requiring improvement. For example, because I did not have the opportunity to verify chemotherapy orders during my PGY-1 residency, my preceptors provided me one-on-one guidance through professional practice experiences to help me become accustomed to the workflow. I would also like to improve my oral chemotherapy counseling skills and would find mock patient education sessions very helpful.
Though I have a structured schedule for the year, I have been given the flexibility to develop my own research project and select clinical trial pharmacy rotations in my areas of interest. The learning experiences are arranged by disease states, and each preceptor has a subspecialty in that disease state. Unlike the situation in other specialties, most oncology disease states are new to the resident, and didactic lectures can therefore be extremely helpful in building one’s knowledge base. For example, my first two rotations were in lymphoma and breast cancer. My preceptors held a number of one-on-one teaching sessions with me, which we spent analyzing patient cases and doing literature reviews, especially during the first week of each rotation. Preparing weekly lectures under the guidance of my preceptors helped me learn in depth about the disease states, treatment options, National Comprehensive Cancer Network guideline recommendations, landmark trials, and agents in the pipeline. In the beginning of the residency I needed more teaching from my preceptors, but I expect that as my oncology knowledge base grows, I will acquire more autonomy.
My learning experiences about clinical trials are incorporated into my core rotations. While providing guideline-based patient care, I will also be learning innovative therapy protocols and witnessing their implementation; MGH has an extensive clinical trials program that is moving oncology practice forward. As the PGY-2 oncology resident at MGH, I feel fortunate to be constantly exposed to the very forefront of oncology practice. In oncology, unlike other specialty practices, numerous clinical trials are conducted; learning how to read a study protocol and search for information in it is a critical skill that every resident must possess. Nevertheless, learning the standard-of-care regimen is the first step before one delves into clinical trials. Preceptors play a pivotal role in helping the resident who is new to the disease state to understand and differentiate among treatment regimens.
Feedback provided by the RPD and preceptors is essential to every resident’s growth. Ever since August 1, when my clinical rotations began, I have been receiving constructive feedback and have been asked to provide feedback. I meet with my preceptor weekly to reflect on the positives and negatives of my training so that we can optimize my learning experience and I can continue to achieve the goals set for each rotation. It is important for the resident to document his or her daily and weekly progress and actively seek feedback from the preceptors so that potential problems are addressed immediately. Also helpful is a 10-minute daily recap with the preceptor to discuss what the resident learned that day and identify areas for improvement. Providing and receiving timely feedback allows the resident to reflect on progress and stay on track with the learning objectives.
The field of oncology is changing rapidly. Although what was learned in pharmacy school may become outdated shortly after graduation, pharmacists still need to apply the methodology of providing pharmaceutical care plans to oncology patients. Residency teaches us a framework for approaching patient cases and further refines the skills we already possess. Oncology pharmacy residency builds a solid foundation for our oncology knowledge and equips us to tackle future challenges in our oncology career.
