PURPOSE

To report historical patterns of pharmaceutical expenditures, to identify factors that may influence future spending, and to predict growth in drug spending in 2024 in the United States, with a focus on the nonfederal hospital and clinic sectors.

METHODS

Historical patterns were assessed by examining data on drug purchases from manufacturers using the IQVIA National Sales Perspectives database. Factors that may influence drug spending in hospitals and clinics in 2024 were reviewed-including new drug approvals, patent expirations, and potential new policies or legislation. Focused analyses were conducted for biosimilars, cancer drugs, endocrine drugs, generics, and specialty drugs. For nonfederal hospitals, clinics, and overall (all sectors), estimates of growth of pharmaceutical expenditures in 2024 were based on a combination of quantitative analyses and expert opinion.

RESULTS

In 2023, overall pharmaceutical expenditures in the US grew 13.6% compared to 2022, for a total of $722.5 billion. Utilization (a 6.5% increase), new drugs (a 4.2% increase) and price (a 2.9% increase) drove this increase. Semaglutide was the top drug in 2023, followed by adalimumab and apixaban. Drug expenditures were $37.1 billion (a 1.1% decrease) and $135.7 billion (a 15.0% increase) in nonfederal hospitals and clinics, respectively. In clinics, increased utilization drove growth, with a small impact from price and new products. In nonfederal hospitals, a drop in utilization led the decrease in expenditures, with price and new drugs modestly contributing to growth in spending. Several new drugs that will influence spending are expected to be approved in 2024. Specialty, endocrine, and cancer drugs will continue to drive expenditures.

CONCLUSION

For 2024, we expect overall prescription drug spending to rise by 10.0% to 12.0%, whereas in clinics and hospitals we anticipate an 11.0% to 13.0% increase and a 0% to 2.0% increase, respectively, compared to 2023. These national estimates of future pharmaceutical expenditure growth may not be representative of any health system because of the myriad of local factors that influence actual spending.

National trends in prescription drug expenditures and projections for 2023

PURPOSE

To report historical patterns of pharmaceutical expenditures, to identify factors that may influence future spending, and to predict growth in drug spending in 2023 in the United States, with a focus on the nonfederal hospital and clinic sectors.

METHODS

Historical patterns were assessed by examining data on drug purchases from manufacturers using the IQVIA National Sales Perspectives database. Factors that may influence drug spending in hospitals and clinics in 2023 were reviewed, including new drug approvals, patent expirations, and potential new policies or legislation. Focused analyses were conducted for biosimilars, cancer drugs, diabetes medications, generics, COVID-19 pandemic influence, and specialty drugs. For nonfederal hospitals, clinics, and overall (all sectors), estimates of growth of pharmaceutical expenditures in 2023 were based on a combination of quantitative analyses and expert opinion.

RESULTS

In 2022, overall pharmaceutical expenditures in the US grew 9.4% compared to 2021, for a total of $633.5 billion. Utilization (a 5.9% increase), price (a 1.7% increase) and new drugs (a 1.8% increase) drove this increase. Adalimumab was the top-selling drug in 2022, followed by semaglutide and apixaban. Drug expenditures were $37.2 billion (a 5.9% decrease) and $116.9 billion (a 10.4% increase) in nonfederal hospitals and clinics, respectively. In clinics, new products and increased utilization growth drove growth, with a small impact from price changes. In nonfederal hospitals, a drop in utilization led to a decrease in expenditures, with price changes and new drugs contributing to growth in spending. Several new drugs that will influence spending have been or are expected to be approved in 2023. Specialty and cancer drugs will continue to drive expenditures along with the evolution of the COVID-19 pandemic.

CONCLUSION

For 2023, we expect overall prescription drug spending to rise by 6.0% to 8.0%, whereas in clinics and hospitals we anticipate increases of 8.0% to 10.0% and 1.0% to 3.0%, respectively, compared to 2022. These national estimates of future pharmaceutical expenditure growth may not be representative of any particular health system because of the myriad of local factors that influence actual spending.

The Current Landscape for METex14 Skipping Mutations in Non–Small Cell Lung Cancer

Capmatinib and tepotinib received US Food and Drug Administration (FDA) approval for mesenchymal-epithelial transition (MET) exon 14 (METex14) skipping alteration in 2020 and 2021, respectively. Capmatinib was FDA approved in May 2020 under accelerated approval for the treatment of patients with metastatic non–small cell lung cancer (NSCLC) whose tumors have a mutation that leads to METex14 skipping. Accelerated approval was based on overall response rate and response duration to capmatinib, and it was granted orphan drug and breakthrough therapy designation. Capmatinib is a potent selective kinase inhibitor of the MET receptor, crosses the blood-brain barrier, and has shown low-grade adverse events. Based on phase II data, capmatinib demonstrated an overall response rate (ORR) of 41% and a median duration of response (DOR) of 9.7 months in those who previously received one or two lines of therapy. In treatment-naive patients, capmatinib demonstrated a 68% ORR with a median DOR of 12.6 months. The FDA also granted accelerated approval to tepotinib for adult patients with metastatic NSCLC harboring METex14 skipping alteration. Accelerated approval for tepotinib was based on an ORR of 43% with a median DOR of 10.8 months in treatment-naive patients. Among previously treated patients, the ORR was 43% with a median DOR of 11.1 months. Continued approval for capmatinib and tepotinib is contingent upon confirmatory trials. Both agents are now considered first-line therapy or a subsequent therapy option in patients with metastatic NSCLC who are positive for METex14 skipping alterations.

National trends in prescription drug expenditures and projections for 2022

Purpose

To report historical patterns of pharmaceutical expenditures, to identify factors that may influence future spending, and to predict growth in drug spending in 2022 in the United States, with a focus on the nonfederal hospital and clinic sectors.

Methods

Historical patterns were assessed by examining data on drug purchases from manufacturers using the IQVIA National Sales Perspectives database. Factors that may influence drug spending in hospitals and clinics in 2022 were reviewed—including new drug approvals, patent expirations, and potential new policies or legislation. Focused analyses were conducted for biosimilars, cancer drugs, generics, COVID-19 pandemic influence, and specialty drugs. For nonfederal hospitals, clinics, and overall (all sectors), estimates of growth of pharmaceutical expenditures in 2022 were based on a combination of quantitative analyses and expert opinion.

Results

In 2021, overall pharmaceutical expenditures in the US grew 7.7% compared to 2020, for a total of $576.9 billion. Utilization (a 4.8% increase), price (a 1.9% increase) and new drugs (a 1.1% increase) drove this increase. Adalimumab was the top drug in terms of overall expenditures in 2021, followed by apixaban and dulaglutide. Drug expenditures were $39.6 billion (a 8.4% increase) and $105.0 billion (a 7.7% increase) in nonfederal hospitals and in clinics, respectively. In clinics and hospitals, new products and increased utilization growth drove growth, with decreasing prices for both sectors acting as an expense restraint. Several new drugs that are likely to influence spending are expected to be approved in 2022. Specialty and cancer drugs will continue to drive expenditures along with the evolution of the COVID-19 pandemic.

Conclusion

For 2022, we expect overall prescription drug spending to rise by 4.0% to 6.0%, whereas in clinics and hospitals we anticipate increases of 7.0% to 9.0% and 3.0% to 5.0%, respectively, compared to 2021. These national estimates of future pharmaceutical expenditure growth may not be representative of any particular health system because of the myriad of local factors that influence actual spending.

Severe Psychiatric Symptoms in a Patient With EGFR Exon-20 Insertion Mutation Receiving Mobocertinib: A Case Report

Tyrosine kinase inhibitor therapy is an established standard of care for patients with NSCLC with EGFR mutations, but a worse prognosis has been observed in patients with specific EGFR exon-20 insertion mutations. Mobocertinib (TAK-788) is a novel tyrosine kinase inhibitor developed to target EGFR exon-20 insertion and has exhibited promising response rates and acceptable safety in phase 1 and 2 trials. We report a case of a 59-year-old woman with metastatic NSCLC and EGFR exon-20 mutation responsive to mobocertinib therapy, who developed severe depression and catatonia approximately 4 months after mobocertinib initiation, ultimately necessitating its permanent discontinuation. Given the observed severe depression in this case report, we recommend that, for patients on mobocertinib who develop neuropsychiatric adverse effects, strong consideration should be given for dose interruption or discontinuation.

Integrating trastuzumab biosimilars and HER2-directed therapies into HER2-positive breast cancer management

The approval of the humanized monoclonal antibody trastuzumab in 1998 changed the trajectory of treatment and subsequent outcomes for patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer and is now the standard of care in the neoadjuvant, adjuvant, and metastatic settings. However, as with most biologic drugs, trastuzumab comes with a relatively high price tag compared with traditional cytotoxic chemotherapy and contributes to healthcare budgets. Three engineered products related to trastuzumab-2 antibody-drug conjugates, ado-trastuzumab emtansine and fam-trastuzumab deruxtecan-nxki, as well as the subcutaneous trastuzumab/hyaluronidase-have since been approved and have expanded the treatment options for this patient population. The approval of 5 trastuzumab biosimilars as of the end of 2019 holds the promise of considerable cost savings, but challenges to integrating their use into patient care must be addressed. Barriers to their use, including physician uncertainty to switch patients from the reference drug to the therapeutic biosimilar and patients' lack of understanding about biosimilars, are common in the United States. It is also important that all stakeholders, including managed care professionals, pharmacists, and practice administrators, understand how to incorporate trastuzumab biosimilars into formulary discussions, clinical care plans and processes, and educational initiatives for healthcare providers and patients.

National trends in prescription drug expenditures and projections for 2021

Purpose

To report historical patterns of pharmaceutical expenditures, to identify factors that may influence future spending, and to predict growth in drug spending in 2021 in the United States, with a focus on the nonfederal hospital and clinic sectors.

Methods

Historical patterns were assessed by examining data on drug purchases from manufacturers using the IQVIA National Sales Perspectives database. Factors that may influence drug spending in hospitals and clinics in 2021 were reviewed—including new drug approvals, patent expirations, and potential new policies or legislation. Focused analyses were conducted for biosimilars, cancer drugs, generics, coronavirus disease 2019 (COVID-19) pandemic influence, and specialty drugs. For nonfederal hospitals, clinics, and overall (all sectors), estimates of growth of pharmaceutical expenditures in 2021 were based on a combination of quantitative analyses and expert opinion.

Results

In 2020, overall pharmaceutical expenditures in the United States grew 4.9% compared to 2019, for a total of $535.3 billion. Utilization (a 2.9% increase) and new drugs (a 1.8% increase) drove this increase, with price changes having minimal influence (a 0.3% increase). Adalimumab was the top drug in 2020, followed by apixaban and insulin glargine. Drug expenditures were $35.3 billion (a 4.6% decrease) and $98.4 billion (an 8.1% increase) in nonfederal hospitals and clinics, respectively. In clinics, growth was driven by new products and increased utilization, whereas in hospitals the decrease in expenditures was driven by reduced utilization. Several new drugs that will influence spending are expected to be approved in 2021. Specialty and cancer drugs will continue to drive expenditures along with the evolution of the COVID-19 pandemic.

Conclusion

For 2021, we expect overall prescription drug spending to rise by 4% to 6%, whereas in clinics and hospitals we anticipate increases of 7% to 9% and 3% to 5%, respectively, compared to 2020. These national estimates of future pharmaceutical expenditure growth may not be representative of any particular health system because of the myriad of local factors that influence actual spending.

National trends in prescription drug expenditures and projections for 2020

Purpose

To report historical patterns of pharmaceutical expenditures, to identify factors that may influence future spending, and to predict growth in drug spending in 2020 in the United States, with a focus on the nonfederal hospital and clinic sectors.

Methods

Historical patterns were assessed by examining data on drug purchases from manufacturers using the IQVIA National Sales Perspectives database. Factors that may influence drug spending in hospitals and clinics in 2020 were reviewed, including new drug approvals, patent expirations, and potential new policies or legislation. Focused analyses were conducted for specialty drugs, biosimilars, and diabetes medications. For nonfederal hospitals, clinics, and overall (all sectors), estimates of growth of pharmaceutical expenditures in 2020 were based on a combination of quantitative analyses and expert opinion.

Results

In 2019, overall US pharmaceutical expenditures grew 5.4% compared to 2018, for a total of $507.9 billion. This increase was driven to similar degrees by prices, utilization, and new drugs. Adalimumab was the top drug in US expenditures in 2019, followed by apixaban and insulin glargine. Drug expenditures were $36.9 billion (a 1.5% increase from 2018) and $90.3 billion (an 11.8% increase from 2018) in nonfederal hospitals and clinics, respectively. In clinics, growth was driven by new products and increased utilization, whereas in hospitals growth was driven by new products and price increases. Several new drugs that will likely influence spending are expected to be approved in 2020. Specialty and cancer drugs will continue to drive expenditures.

Conclusion

For 2020 we expect overall prescription drug spending to rise by 4.0% to 6.0%, whereas in clinics and hospitals we anticipate increases of 9.0% to 11.0% and 2.0% to 4.0%, respectively, compared to 2019. These national estimates of future pharmaceutical expenditure growth may not be representative of any particular health system because of the myriad of local factors that influence actual spending.

National trends in prescription drug expenditures and projections for 2019

PURPOSE

Historical trends and factors likely to influence future pharmaceutical expenditures are discussed, and projections are made for drug spending in 2019 in nonfederal hospitals, clinics, and overall (all sectors).

METHODS

Drug expenditure data through calendar year 2018 were obtained from the IQVIA National Sales Perspectives database and analyzed. New drug approvals, patent expirations, and other factors that may influence drug spending in hospitals and clinics in 2019 were also reviewed. Expenditure projections for 2019 for nonfederal hospitals, clinics, and overall (all sectors) were made through a combination of quantitative analyses and expert opinion.

RESULTS

U.S. prescription sales in calendar year 2018 totaled $476.2 billion, a 5.5% increase from 2017 spending. The top 3 drugs by expenditures were adalimumab ($19.1 billion), insulin glargine ($9.3 billion), and etanercept ($8.0 billion). Prescription expenditures in nonfederal hospitals totaled $35.8 billion, a 4.8% increase from 2017. Expenditures in clinics in 2018 increased by 13.0% to $80.5 billion. The increase in spending in nonfederal hospitals was largely driven by new products and increased utilization of existing products. The list of the top 25 drugs by expenditures in nonfederal hospitals and clinics was dominated by specialty drugs.

CONCLUSION

We predict continued moderate growth of 4-6% in overall drug expenditures (across the entire U.S. market). We expect the clinic sector to continue to experience high (11-13%) growth in drug spending in 2019. Finally, for nonfederal hospitals we anticipate growth in the range of 3-5%. These estimates are at the national level. Health-system pharmacy leaders should carefully examine local drug utilization patterns to determine their own organization's anticipated spending in 2019.

Pharmacist perspectives and considerations for implementation of therapeutic oncology biosimilars in practice

Purpose

An overview of therapeutic oncology biosimilars, the U.S. biosimilars regulatory pathway, and the clinical development of selected biosimilar products is provided, including discussion of considerations in adopting biosimilars into oncology practice.

Summary

Biosimilars are biologic agents that are highly similar to and have no clinically meaningful differences from an approved reference product in terms of safety, purity, and potency. There is a large market for cancer biologics, and approval of biosimilars has the potential to increase access to care and reduce costs. An abbreviated regulatory pathway for the development and approval of biosimilars defines a stepwise approach to demonstrating biosimilarity and conducting clinical comparative trials to confirm equivalent pharmacokinetics, efficacy, safety, and immunogenicity to the reference product. Three therapeutic biologics (bevacizumab, trastuzumab, and rituximab) have been used extensively in the treatment of a variety of cancers and are targets for biosimilar product development. Preclinical and clinical experience with 2 recently approved biosimilars to bevacizumab and trastuzumab is reviewed. Challenges faced by pharmacy and therapeutics committees when considering oncology biosimilars for formulary inclusion are discussed.

Conclusion

Increased adoption of biosimilars could potentially lower treatment costs and improve access to biologics for patients with cancer. Key considerations in formulary review of biosimilars include the quality and quantity of data from comparative clinical trials, economic factors, manufacturer reliability, and challenges associated with incorporating biosimilars into practice.

Timely administration of antibiotics in febrile neutropenia per updated ASCO/IDSA guidelines

41

Background: Current ASCO guidelines for management of febrile neutropenia (FN) recommend initial antibiotic administration within one hour of triage, and initial assessment within 15 minutes of triage for patients presenting with FN within 6 weeks of chemotherapy. The University of Illinois Cancer Center (UICC) implemented an early identification and management strategy in the ambulatory setting for FN in 2017, with success in increasing the percentage of FN patients receiving antibiotics within 2 hours from 50% to 92% over a 6 months (05/2017-11/2017) period. Given updated joint ASCO/IDSA guidelines, we aimed to increase percentage of FN patients receiving antibiotics within 1 hour from 56% to more than 90% over 16 months. Methods: A multidisciplinary team involving oncology, hematology (attendings and fellows), pharmacy, and nursing met quarterly to review FN cases including time to antibiotic administration and documentation of prompt assessment. Two Plan-Do-Study-Act (PDSA) cycles were completed, including development and deployment of an electronic medical record automated order set and targeted education for fellows and nurses. Results: Between 12/17 and 04/19, of 7 patients with FN, 100% (N = 7) received antibiotics in clinic. The percentage of FN patients receiving antibiotics within 1 hour of triage post first and second interventions was as follows: 25% (N = 1), 100% (N = 4). 100% (N = 7) of FN patients had documentation of prompt assessment, but time from triage was not specified. Conclusions: We were successful in improving the percentage of FN patients receiving antibiotics from 56% to more than 90% over 16 months. We are targeting our next PDSA cycle to increase assessments within 15 minutes of triage. Additional future interventions include tailoring antibiotics based on FN with low or high risk of complication via focus group and root case analyses discussion with our attendings, fellows, and nurses, and collaborating with ED on a standard care pathway for FN management.

Universal hepatitis B screening in a high risk community

244

Background: 2015 ASCO guidelines for Hepatitis B (HBV) screening in patients (pts) receiving chemotherapy recommend a risk-adaptive strategy considering patient and treatment-specific factors. The University of Illinois Cancer Center (UICC) is an academic center with largely underserved, minority and socioeconomically disadvantaged pts. UICC implemented a universal HBV screening policy in 2016. We aimed to increase HBV screening from 60% to 95% over 18 months. Methods: A multidisciplinary team of oncologists, hepatologists, fellows, nurses and pharmacists created an ideal process map for universal HBV screening in all pts starting chemotherapy outlining screening parameters, laboratory tests required and follow-up for positive screens. Four Plan-Do-Study-Act cycles were tested. Interim analysis was done targeting specific providers for additional education. Results of screening were analyzed by chart review. Results: A total of 589 treatment-naive pts were screened for HBV between Aug 2017 and Feb 2019. Educational sessions were held for nurses, pharmacists and fellows to review ideal process maps between Jan and March 2018. 0% of pts had insurance denials for HBV screening coverage. Screening rates improved from 65% in Aug 2017 to 100% in Feb 2019. Positive HBV screen rate was 3% (N = 18) and all were new diagnoses. 61% (N = 11) of positive screens had no risk factors for HBV exposure and would not have met risk adaptive criteria for screening. 27% (N = 3) of positive screens without prior risk factors were initiated on prophylactic ART. 50% (N = 9) of all new HBV diagnoses initiated prophylactic ART to prevent reactivation, while 50% received active surveillance on chemotherapy. 0% of pts on active surveillance developed reactivation. Conclusions: Implementing and sustaining a universal HBV screening program was feasible and effective in identifying pts at risk for reactivation in a high risk population. 61% of positive screens lacked traditional risk factors. Risk-adaptive screening may miss cases in diverse populations where HBV is not endemic, precluding appropriate management. Further evaluation will include expanding screening to inpatient chemotherapy starts and cost-benefit analysis of universal screening in this unique population.

Patient-centered design in developing a mobile application for oral anticancer medications

OBJECTIVES

To develop and test the usability and feasibility of a customizable mobile application (app) designed to help educate patients about their oral anticancer medications (OAMs) and regimens.

SETTING

Outpatient cancer center and oncology pharmacy for urban, Midwestern academic health system.

PRACTICE DESCRIPTION

Clinically-supervised educational intervention to support patients learning about OAMs.

PRACTICE INNOVATION

With input from patient partners, our interdisciplinary team designed the first known tablet-based educational app that can interface with a patient's electronic medical record. The app is based on learning style and adherence theories and is customizable for individually prescribed OAMs. The app can accommodate multiple learning styles through text at 6th-grade reading level, pictures, animations, and audio voiceovers. Functionalities include interactive educational modules on 11 OAMs and case-based patient stories on common barriers to OAM adherence.

EVALUATION

Early phase testing provided the opportunity to observe the user interface with the app and app functionality. Data were summarized descriptively from observations and comments of patient subjects.

RESULTS

Thirty patient subjects provided input-19 in phase 1 usability testing and 11 in phase 2 feasibility testing. Comments provided by patient subjects during usability testing were largely positive. Responses included self-identification with patient stories, usefulness of drug information, preferences for text messages, and app limitations (e.g., perceived generational digital divide in technology use and potential patient inability to receive text messages). Using their feedback, modifications were made to the prototype app. Responses in feasibility testing demonstrated the app's usefulness across a wide range of ages. Highest opinion ratings on app usefulness were stated by patients who were newer to OAM therapy.

CONCLUSION

User feedback suggests the potential benefit of the app as a tool to help patients with cancer, particularly after the first months for those starting new OAM regimens. Processes and lessons learned are transferable to other settings.

Role of HIV in the desire of procreation and motherhood in women living with HIV in Spain: a qualitative approach

Background

Improved antiretroviral treatments and decrease in vertical transmission of HIV have led to a higher number of women living with HIV to consider childbearing. However, stigma and social rejection result in specific challenges that HIV positive women with procreation intentions have to face with. Our objective was to in depth analyse elements shaping their desire for procreation and specifically investigate the impact of HIV.

Methods

A qualitative study was conducted through open interviews with 20 women living with HIV between 18 and 45 years of age, from the Spanish AIDS Research Network Cohort (CoRIS). Interviews were audio-recorded and transcribed. A content analysis was performed.

Results

HIV diagnosis is a turning point in women’s sexual and emotional life that is experienced traumatically. HIV diagnosis is usually associated with the fear of an immediate death and the idea of social isolation. At this moment, women temporarily reject future motherhood or having a sexual life. HIV status is only disclosed to the closed social circle and partner support is essential in HIV diagnosis assimilation process. Health professionals provide information on assisted reproductive technology and on how to minimize risk of partner HIV transmission. Most of barriers for procreation acknowledged by women are not related to HIV. However, women fear vertical transmission and experience other barriers derived from HIV infection. In this context, pregnancy makes women feel themselves as “normal women” despite HIV. Motherhood is considered an element of compensation that helps them to cope with HIV diagnosis. All these elements make health professionals key actors: they provide information and support after HIV diagnosis.

Conclusions

Barriers and drivers for procreation are similar among HIV positive women and general population. However, stigma and discrimination linked with HIV weigh in HIV positive women decision of motherhood. In this context, it is necessary to provide these women with the necessary counselling, guidance and resources to take decisions about procreation properly informed.

BCR-ABL1 tyrosine kinase inhibitors for the treatment of chronic myeloid leukemia

The management of chronic myeloid leukemia with BCR-ABL1 tyrosine kinase inhibitors has evolved chronic myeloid leukemia into a chronic, manageable disease. A patient-centered approach is important for the appropriate management of chronic myeloid leukemia and optimization of long-term treatment outcomes. The pharmacist plays a key role in treatment selection, monitoring drug–drug interactions, identification and management of adverse events, and educating patients on adherence. The combination of tyrosine kinase inhibitors with unique safety profiles and individual patients with unique medical histories can make managing treatment difficult. This review will provide up-to-date information regarding tyrosine kinase inhibitor-based treatment of patients with chronic myeloid leukemia. Management strategies for adverse events and considerations for drug–drug interactions will not only vary among patients but also across tyrosine kinase inhibitors. Drug–drug interactions can be mild to severe. In instances where co-administration of concomitant medications cannot be avoided, it is critical to understand how drug levels are impacted and how subsequent dose modifications ensure therapeutic drug levels are maintained. An important component of patient-centered management of chronic myeloid leukemia also includes educating patients on the significance of early and regular monitoring of therapeutic milestones, emphasizing the importance of adhering to treatment in achieving these targets, and appropriately modifying treatment if these clinical goals are not being met. Overall, staying apprised of current research, utilizing the close pharmacist–patient relationship, and having regular interactions with patients, will help achieve successful long-term treatment of chronic myeloid leukemia in the age of BCR-ABL1 tyrosine kinase inhibitors.

Design of Customized Mobile Application for Patient Adherence to Oral Anticancer Medications Utilizing User-Centered Design

Adherence and compliance to oral anticancer medications (OAMs) can be challenging for patients due to their complex regimens. The goal of this research project was to design an effective and engaging user interface (UI), based on user-centered design (UCD) and incorporate animations, to reinforce and improve patient's understanding of the key aspects of taking OAMs. This current paper encompasses the development process and describes the initial phase of the project, which focused on the design and development of the tablet-based educational application (app). A UCD approach was implemented by consulting with oncology clinicians and patients at an early stage of development. Animations were developed and incorporated to convey complex medical concepts and information. An iterative design process will help ensure that the tool is customized for patient engagement.

Hepatitis B virus screening in patients receiving intravenous chemotherapy

205

Background: Patients with chronic hepatitis B (HBV) who undergo chemotherapy without antiviral prophylaxis may develop HBV reactivation, hepatitis, liver injury, and even death. The University of Illinois Cancer Center (UICC) lacks a standardized guideline for screening patients for HBV prior to chemotherapy initiation. A retrospective chart review was conducted on chemotherapy orders submitted to UICC pharmacy over 4 weeks for both hematological and solid tumor malignancies. Of 63 new orders for intravenous chemotherapy, only 14 patients (22%) underwent HBV screening prior to chemotherapy initiation. We aimed to increase HBV screening from 22% to 50% over 2 months. Methods: A multidisciplinary taskforce comprised of hematology/oncology and hepatology physicians, clinical pharmacy, and nursing was created. An ideal process map was created identifying a clear management schema for HBV screening including differences in screening tests for various populations and management recommendations for positive test results. Two Plan-Do-Study-Act (PDSA) cycles were tested with post intervention data collected over eight weeks. Results: Of 192 chemotherapy orders submitted to outpatient pharmacy over 8 weeks, 62 patients (32%) were determined to be appropriate for HBV screening prior to initiation of chemotherapy. Of these, 36 patients (58%) were screened appropriately for HBV. Additionally, a subset analysis revealed 100% of patients successfully screened for HBV prior to initiation of anti-CD20 therapies. Conclusions: At UICC, a multidisciplinary team created and successfully piloted the implementation of a HBV screening policy in both hematological and solid tumor malignancies. Our initial aim was reached after 8 weeks of implementation, and ongoing efforts are being conducted to further improve HBV screening rates to 90%.

Pharmacological management of anticancer agent extravasation: A single institutional guideline

Although the risk of extravasation of a chemotherapy (anticancer) medication is low, the complications associated with these events can have a significant impact on morbidity and health care costs. Institutions that administer anticancer agents should ideally have a current guideline on the proper management of the inadvertent administration of these toxic medications into tissues surrounding blood vessels. It is imperative that the health care team involved in administering drugs used to treat cancer be educated on the risk factors, preventative strategies and treatment of anticancer extravasations, as well as practice safe and proper administration techniques. Anticancer agents are generally divided into classes based on their ability to cause tissue damage. The review of current published guidelines and available literature reveals a lack of consensus on how these medications should be classified. In addition, many recently approved drugs for the treatment of cancer may lack data to support their classification and management of extravasation events. The treatment of the majority of extravasations of anticancer agents involves nonpharmacological measures, potentially in the ambulatory care setting. Antidotes are available for the extravasation of a minority of vesicant agents in order to mitigate tissue damage. Due to the limited data and lack of consensus in published guidelines, a working group was established to put forth an institutional guideline on the management of anticancer extravasations.

Documentation of pharmacist-provided patient education for oral chemotherapy

237

Background: Pharmacist-provided patient education for oral chemotherapy is poorly documented in patient electronic medical records (EMR) at UIC Oncology Pharmacy. At baseline, 41% of patients who started new therapy with selected oral chemotherapies had a patient education note documented by a pharmacist in their EMR. Our aim is to provide and document patient education for at least 90% of patients who start new oral chemotherapy and fill their prescriptions at UIC Oncology Pharmacy over three months. The importance of patient counseling and documentation is recognized by the Quality Oncology Practice Initiative (QOPI) group. Approximately 25% of patients undergoing chemotherapy are on oral chemotherapy. (Deutsch S, Koerner P, Miller RT, Craft Z, Fancher K. Utilization patterns for oral oncology medications in a specialty pharmacy cycle management program. J Oncol Pharm Pract. 2014;0:1-8.) Methods: A multi-disciplinary team performed an affinity sort and created a process map to identify areas of intervention. The first intervention was labelling prescription bags to identify them as oral chemotherapy prescriptions that require counseling by a pharmacist. Data was collected after two weeks. Results: At the completion of the first PDSA cycle, 40% of patients who started new oral chemotherapy had a documented patient education note written by a pharmacist in their EMR. Documentation of education was performed on the day of pick-up in 89% of cases. Table 1 shows the percentage of notes that included the elements recognized by QOPI standards: documentation of start date, adherence, and adverse effects. Conclusions: Documentation of patient education for oral chemotherapy should be a well-integrated component of ambulatory pharmacy practice. A second PDSA cycle is planned to increase rates of documentation by utilizing the pharmacy resident to perform patient counseling and documentation. Future interventions will be aimed at improving the quality of the data included in the documented notes. [Table: see text]

[Boosted protease inhibitor monotherapy in HIV-infected patients: results of a study in a real life setting]

BACKGROUND

Boosted protease inhibitor monotherapy may offer antiviral efficacy while reducing drug interactions, costs and toxicity. The aim of this study was to assess the efficacy of darunavir/ritonavir (DRV/r) and lopinavir/ritonavir (LPV/r) monotherapy in a real life setting.

METHODS

A retrospective analysis of all HIV infected patients, who had initiated DRV/r or LPV/r monotherapy, was performed. Patients whose HIV viral load had remained undetectable for at least two consecutive follow-up visits and who had no neurocognitive disorder or hepatitis B co-infection, were included.

RESULTS

Sixty patients were included. The median (IQR) time to follow-up was 66 (33-118) weeks. The proportions (CI95%) of patients with virological failure were 6.3% (1.7- 20.2) and 25.0% (12.7-43.4), respectively, in the DRV/r and LPV/r groups (p= 0.0424). The proportions (CI95%) of patients with therapeutic success were 90.6% (80.5-100) in the DRV/r group and 60.7% (42.6-78.8) in the LPV/r group (p=0.0063). No protease inhibitor mutations were detected. During the follow-up, 6 patients with dyslipidemia normalized their lipid values. The median monthly cost was 410 (IQR 242-416) euros per person lower for the monotherapy than for the combined antiretroviral therapy.

CONCLUSIONS

Boosted protease inhibitor monotherapy was effective in a real life setting. This study showed differences in favour of DRV/r as compared with LPV/r in terms of therapeutic success; however prospective studies are needed to confirm these results. Finally, although this study was not specifically designed to detect benefits in terms of costs and lipid profile, it shows evidence of a positive impact of monotherapy in these fields.

Targeting the mammalian target of rapamycin pathway with everolimus: implications for the management of metastatic breast cancer

The inhibitors of mammalian target of rapamycin (mTOR) have documented antitumor activity via disruption of various signaling pathways leading to impaired cellular growth, proliferation, and survival. In preclinical studies, mTOR inhibitors use in combination with hormonal therapy has shown promising results in overcoming endocrine resistance in breast cancer cells. The role of everolimus in breast cancer was established in the Breast Cancer Trial of Oral Everolimus-2 (BOLERO-2) trial in combination with exemestane for patients with advanced metastatic hormone receptor-positive (HR+) breast cancer, who relapsed after initial hormonal manipulation. The study met its primary endpoint of significant improvement in progression free survival (PFS) with a median time to progression of 6.9 months in the combination group versus 2.8 months in exemestane group. Favorable improvements in PFS were reported across all patient subgroups regardless of age, Eastern Cooperative Oncology Group performance status, number of prior therapies, and presence of visceral metastases. Adverse events were mostly mild to moderate in severity and consistent with the known safety profile of everolimus. Major toxicities reported include stomatitis, non-infectious pneumonitis, and hyperglycemia. The purpose of this review is to discuss the role of everolimus as a valuable component in advanced metastatic breast cancer and delineate current strategies to prevent and manage the most common toxicities associated with this combination regimen.

The life, death, and attempted rebirth of bevacizumab in breast cancer

Breast cancer is the leading cause of cancer in women. In recent years, there has been immense drug discovery and development in the field of breast cancer. Most recently, the role of vascular endothelial growth factor has moved to the treatment forefront with bevacizumab immersed into the literature as well as the media. Bevacizumab, a vascular endothelial growth factor inhibitor FDA approved for the treatment of other cancers, was first studied in metastatic breast cancer. Its use in human epidermal growth factor receptor 2–negative metastatic breast cancer ultimately failed to show an improvement in overall survival in landmark trials (E2100, AVADO, RIBBON-1 and RIBBON-2) despite its positive impact on progression-free survival. The role is yet to be determined in triple negative breast cancer as well as in the adjuvant and neoadjuvant settings. Trends begin to emerge as bevacizumab is combined with other chemotherapeutic drugs in terms of toxicities. The addition of bevacizumab is associated with an increase in the dose-limiting toxicities of the drugs combined in the regimen. As previous literature suggest, hypertension and proteinuria were also seen with the addition of bevacizumab, both of which are known adverse events. Lastly, there is a trend towards increased incidence of heart failure when bevacizumab is combined with another cardiotoxic medication, doxorubicin. This toxicity has been shown to be reversible in the majority of the cases and has a low incidence in the currently published literature.

Novel targets in the treatment of advanced melanoma: new first-line treatment options

OBJECTIVE

To discuss the clinical efficacy and safety of ipilimumab, vemurafenib, and investigational agents for the treatment of unresectable stage III and stage IV melanoma and define current strategies of first-line treatment selection.

DATA SOURCES

Literature was accessed through MEDLINE and International Pharmaceutical Abstracts (1970-November 2012) using the terms melanoma, metastatic melanoma, ipilimumab, vemurafenib, dabrafenib, and trametinib. In addition, reference citations from publications identified were reviewed.

STUDY SELECTION AND DATA EXTRACTION

All articles published in English identified from the data sources were evaluated. Studies and abstracts including more than 10 adult patients were included in the review.

DATA SYNTHESIS

Treatment options for unresectable stage III and IV melanoma are poor and have remained largely unchanged for the past 40 years. Two randomized Phase 3 clinical trials have demonstrated a significant survival benefit with the use of ipilimumab compared to a melanoma vaccine (10.1 vs 6.4 months; p = 0.003) and compared to dacarbazine (11.2 months, 95% CI 9.4-13.6 vs 9.1 months, 95% CI 7.8-10.5). Additionally, long-term follow-up has revealed cases of durable responses of greater than 3 years. Response rates of 50% and greater have been described in vemurafenib-treated patients (1 Phase 1, 1 Phase 2, and 1 Phase 3 randomized trial), although duration of response has not been fully determined. Both new agents possess unique toxicity profiles including immune-related adverse events with ipilimumab and secondary cutaneous cancers reported with vemurafenib use.

CONCLUSIONS

Treatment strategies have changed for patients with advanced melanoma with the use of ipilimumab and vemurafenib as first-line agents. Increased clinical experience and further published data with these and investigational agents will guide the development of treatment algorithms outlining optimal drug selection and sequencing as well as improve management of their novel adverse events.

Bevacizumab-induced oral mucositis in background of cutaneous plaque-type psoriasis

OBJECTIVE

To report the serial development of oral mucositis following infusion of bevacizumab in a young woman with a malignant brain tumor and history of cutaneous psoriasis.

CASE SUMMARY

A 29-year-old woman with a history of active cutaneous psoriasis and a malignant glioneuronal tumor was treated with bevacizumab for 2.5 years. With each infusion of bevacizumab, she developed oral mucositis within 36 hours. She received temozolomide as part of concurrent therapy with radiation and as maintenance therapy; it was discontinued after continuous therapy for 1.5 years. Bevacizumab 10 mg/kg was added after 7 cycles of maintenance temozolomide, as the tumor had minimal response and evidence of increased perfusion with angiogenesis on imaging studies. All medication, including temozolomide, was evaluated and eventually discontinued, with the exception of bevacizumab, which remained the drug suspected of causing the mucositis.

DISCUSSION

Oral mucositis is a frequent adverse effect of cytotoxic chemotherapy, but has not been reported with bevacizumab. The Naranjo probability scale indicated a probable adverse drug reaction. This likely indicates that bevacizumab is one of many drugs known to induce exacerbation of psoriatic disease. We speculate that oral mucositis developed as bevacizumab-induced generation of proinflammatory cytokines within the vascular endothelium, leading to mucosal damage and ulceration. In addition, interruption of reparative angiogenic pathways with bevacizumab likely contributed to the severity of mucositis.

CONCLUSIONS

Clinicians should be aware that bevacizumab can potentially exacerbate psoriatic disease.

Transfusions increase with nationally driven reimbursement changes of erythropoiesis stimulating agents for chemotherapy-induced anemia

Background. The Centers for Medicare and Medicaid Services (CMS) issued a national coverage determination (NCD) in July 2007, which imposed restrictions on the reimbursement of ESAs for Medicare and Medicaid beneficiaries. Since a majority of our patients are Medicare or Medicaid beneficiaries, we changed our clinical practice regarding the use of erythropoiesis stimulating agents (ESAs) to coincide with the NCD’s reimbursement restriction.

Objective. To evaluate the number of transfusions in patients diagnosed with chemotherapy-induced anemia (CIA) receiving ESAs before and after the clinical practice was changed at the University of Illinois Medical Center (UIMC).

Methods. The medical records of all adult patients diagnosed with a nonmyeloid malignancy and CIA who received an ESA between July 2006 and June 2008 at the UIMC were evaluated. The patients were divided into two groups: patients in receipt of ESAs BEFORE (group 1) and AFTER (group 2). The number of transfusions, the response rates to chemotherapy and ESAs therapy, and overall survival were compared.

Results. Medical records for 110 patients were reviewed. More transfusions were given to patients AFTER we implemented the change in clinical practice (BEFORE 18 transfusions vs. AFTER 52 transfusions, p = 0.004). More patients responded to ESA therapy AFTER we implemented the change (67% vs. 83%, p = NS). The treatment response to chemotherapy and overall survival were similar between the two groups.

Conclusion. The primary goal of reducing the number of transfusions in patients with CIA by administering ESAs cannot be met when clinical practice coincides with the NCD.

Understanding and managing the possible adverse effects associated with bevacizumab

PURPOSE

The adverse events associated with bevacizumab therapy are characterized, and the underlying pathophysiology, risk factors, frequency, and management of these events are described.

SUMMARY

The adverse events associated with bevacizumab include hypertension, proteinuria, thromboembolism, impaired wound healing, bleeding, perforation, reversible leukoencephalopathy syndrome, skin rash, and infusion-related hypersensitivity reactions. Patients should be monitored for these events throughout the course of bevacizumab therapy. Hypertension is by far the most common adverse event associated with bevacizumab. Blood pressure should be routinely monitored, and hypertension should be medically managed with antihypertensive drugs as deemed appropriate during bevacizumab therapy. Patients should be monitored for proteinuria every three to four weeks, and bevacizumab should be discontinued with persistent proteinuria of >2+. Thromboembolic events, impaired wound healing, bowel and nasal septum perforation, and bleeding share similar pathophysiology. Thromboembolic events should be managed in accordance with guidelines established by the American College of Chest Physicians, and bevacizumab should be discontinued for new life-threatening venous or arterial thromboembolism. To minimize the risk of bleeding or impaired wound healing, bevacizumab should be started at least four weeks after surgery or discontinued for at least six to eight weeks before elective surgery. The management of other adverse events is more anecdotal, with relatively few reports of their occurrence with bevacizumab.

CONCLUSION

Many of the potential serious complications of bevacizumab can be averted by close monitoring of patient-specific variables, which should be measured at baseline and then at predetermined intervals throughout the course of therapy to maximize patient safety.

Complete response of CNS-involved olfactory neuroendocrine tumor using multimodal therapy

INTRODUCTION

Locally advanced tumors in the olfactory area commonly have central nervous system (CNS) involvement and are often incurable.

CASE REPORT

We report the treatment of a 25-year-old male patient who presented with a large, neuroendocrine tumor arising from the ethmoid complex. This locally invasive lesion extended beyond the orbits and into the anterior cranial fossa with associated intracranial involvement. An endoscopic nasal biopsy demonstrated a poorly differentiated neuroendocrine tumor. The patient was treated with 4 cycles of combination induction chemotherapy with irinotecan and cisplatin followed by radiation therapy with concurrent weekly cisplatin. He had a complete response to this therapy confirmed with biopsies that demonstrated no residual disease at 8 weeks after chemoradiotherapy. He remained disease free one and a half years following surgery.

CONCLUSION

To our knowledge, this combination treatment approach has not been reported in the literature.

Parenteral iron with erythropoiesis-stimulating agents for chemotherapy-induced anemia

Purpose. To discuss the clinical issues we addressed in the development of our institutional guidelines regarding the assessment of iron stores for cancer- and treatment-related anemia and the administration of parenteral iron with erythropoiesis-stimulating agents (ESAs).

Data sources. Studies published from January 1995 to August 2007 were identified by computer searches of Medline and hand searching of bibliographies of the articles identified via the computer searches. The current clinical practice guidelines were identified by computer searches of the web sites for national professional organizations that represent health care professionals who treat patients with cancer.

Results of data analysis. Hematopoietic responses demonstrate that epoetin alfa and darbepoetin alfa provide similar outcomes for patients with chemotherapy-induced anemia (CIA); however, up to 50% of patients receiving these agents fail to adequately respond. Functional iron deficiency defined as a state of iron-restricted erythropoiesis is likely the primary contributor to the lack of response. Hematopoietic responses following ESA therapy with parenteral iron are substantially higher compared to response with no or oral iron.

Conclusions. Iron stores should be assessed in all patients with cancer- or treatment-related anemia and parenteral iron should be administered to patients receiving ESA therapy to improve hematopoietic response. A unique algorithm that summarizes our institutional guidelines to assess iron stores and administer parenteral iron with ESA therapy in patients with CIA is included.

Examining ethnic differences for bevacizumab-induced hypertension and proteinuria

21168

Background: Bevacizumab is an increasingly used anti-cancer treatment with common side effects including hypertension (htn) and proteinuria which occur in approximately 10% and 20% of the patients, respectively. Little is known regarding ethnic variations of bevacizumab induced htn and proteinuria, particularly in African-Americans (AA) who have a high prevalence of htn and susceptibility to kidney disease. Methods: We conducted a retrospective chart review of patients who completed bevacizumab alone or as a chemotherapy regimen at the University of Illinois at Chicago for an 18-month study period. We collected blood pressure (BP) measurements and urinanalyses before starting bevacizumab, during bevacizumab and after stopping bevacizumab, in addition to concurrent medications, past medical history and demographics. Htn and proteinuria were graded by CTC v3.0. Patients with less than two successive doses of bevacizumab or unreliable ethnicity were excluded. Results: 27 subjects were eligible. Eighteen AA (67%) and 9 (33%) non-AA were included. Twenty-two (81%) had colorectal cancer. AA received a median of 10 cycles and non-AA received a median of 6 cycles. Six subjects (22%) developed any grade htn toxicity; maximum grade: grade 2=4 (15%), grade 3=2 (7%). Htn toxicity occurred in 28% AA and 11% non-AA (p=NS). Previous history of hypertension was found in 15 subjects (55%): AA=14 vs. non-AA=1 (p=0.002) and was not correlated with hypertensive toxicity. Twelve subjects (44%) developed any grade proteinuria; maximum grade: grade 1=9 (33%), grade 2=3 (11%). Proteinuria toxicity occurred in 50% AA and 33% non-AA (p=NS). Presence of hypertensive toxicity was associated with increased risk of proteinuria. Clinical benefit (PR, SD) was seen in 15 subjects (55%). Rate of clinical benefit was 67% in AA and 33% in non-AA (p=NS). Clinical benefit did not correlate with hypertensive or proteinuria toxicities. Conclusions: AA were more prone than non-AA to bevacizumab induced hypertension and proteinuria toxicity in this retrospective study. Higher clinical benefit was seen in AA.

Comparing carboplatin dose administered to the calculated dose using the Modification of Diet and Renal Disease (MDRD) equation

13003

Background: Renal function assessment is vital for dosing of chemotherapy drugs. GFR is usually estimated by creatinine clearance (CrCl). The MDRD equation is thought to provide a more accurate estimation of GFR than the Cockcroft-Gault or 24-hour CrCl measurement. Although this formula has been validated in kidney disease, it has not been extensively studied in cancer patients. Methods: We retrospectively reviewed records for patients who received carboplatin from the University of Illinois at Chicago for a 4-year study period. General demographic information, carboplatin dose for cycles one to three, and common laboratory parameters at baseline and following cycles one to three were collected. The MDRD derived value of GFR was then used in the Calvert equation to calculate carboplatin dose. This calculated dose was compared to the actual dose administered in the first cycle. From this comparison, the records were divided into two groups: (A) actual vs. calculated dose ≥ 20% and (B) actual vs. calculated dose < 20%. We then assessed toxicity by determining the frequency in each group requiring dose reduction on the second cycle of carboplatin. Results: Data are available for 116 patient comparisons. 78 patient comparisons were in group B with agreement between actual vs. calculated MDRD dose. 38 were in group A with 36 having the actual dose being ≥ 20% less than the MDRD-calculated dose. Wilcoxin and Chi analysis reveals statistical significance for African American, women, lower serum creatinine, and older age for Group A. In Group A, cycle 2 dose reductions were made in 3 cases (8% and due to hematologic). In Group B, cycle 2 dose reductions were made in 12 cases. In 8 of these cases (10%), dose reductions were based on ANC, and in 4 cases dose reductions were made likely on the basis of changes in weight or creatinine. Conclusion: In the comparisons examined to date, differences in carboplatin doses due to different methods of calculation do not appear to significantly influence the frequency of dose reduction. Factors used in calculating MDRD such as age, sex, serum creatinine, and ethnicity were variables associated with ≥ 20% difference in actual vs. calculated MDRD dose.

Influence of maternal dietary zinc intake on in vitro tubulin polymerization in fetal rat brain

The hypothesis that one of the biochemical lesions underlying zinc deficiency-induced teratogenicity is altered microtubule formation was tested. Day 19 fetuses from zinc-deficient Sprague-Dawley dams were characterized by low brain supernate zinc concentrations and slow brain tubulin polymerization rates compared to controls. Brain supernate tubulin and protein concentrations were similar in zinc-deficient and control fetuses. In vitro brain tubulin polymerization rates were increased following addition of zinc to either control or zinc-deficient brain supernates; however, the stimulatory effect of added zinc on polymerization was significantly higher in brain supernates obtained from zinc-deficient fetuses compared to controls. These results support the idea that one effect of fetal zinc deficiency is a reduction in tubulin polymerization, which in turn may result in altered microtubule function.
