Sacituzumab Govitecan for Metastatic Triple-Negative Breast Cancer: Clinical Overview and Management of Potential Toxicities.

Patients with metastatic triple-negative breast cancer have a poor prognosis. Sacituzumab govitecan (IMMU-132) is an antibody-drug conjugate that contains the irinotecan active metabolite, SN-38, linked to a humanized monoclonal antibody targeting trophoblast cell surface antigen 2, which is overexpressed in many solid tumors. In a basket design phase I/II study, sacituzumab govitecan demonstrated promising single-agent therapeutic activity in multiple cancer cohorts, leading to accelerated approval by the U.S. Food and Drug Administration of sacituzumab govitecan-hziy (TRODELVY) for the treatment of patients with metastatic triple-negative breast cancer who had received at least two prior therapies in the metastatic setting. Recently, results of the phase III trial, ASCENT, were confirmatory. There is limited available information on the adverse event management with sacituzumab govitecan needed to maximize the dose and duration of effective therapy while maintaining patient quality of life. This review summarizes the clinical development and the practical management of patients receiving sacituzumab govitecan. Sacituzumab govitecan has a well-defined and manageable toxicity profile, and rapid recognition and appropriate early and proactive management will allow clinicians to optimize sacituzumab govitecan treatment for patients. IMPLICATIONS FOR PRACTICE: Sacituzumab govitecan (TRODELVY) is a novel antibody-drug conjugate composed of the active metabolite of irinotecan (SN-38) conjugated to a monoclonal antibody targeting trophoblast cell surface antigen 2, an epithelial cell surface antigen overexpressed in many cancers. Because of the rapid approval of sacituzumab govitecan, there is limited available information on adverse event (AE) management with this agent. As such, this article reviews the clinical development of the drug, the AE profile, and provides recommendations regarding AE management to help optimize therapy with sacituzumab govitecan.

Pilot Randomized Trial of a Pharmacy Intervention for Older Adults with Cancer.

BACKGROUND: Oncology clinicians often struggle with managing medications and vaccinations in older adults with cancer. We sought to demonstrate the feasibility and preliminary efficacy of integrating pharmacists into the care of older adults with cancer to enhance medication management and vaccination administration. METHODS: We randomly assigned patients aged ≥65 years with breast, gastrointestinal, or lung cancer receiving first-line chemotherapy to the pharmacy intervention or usual care. Patients assigned to the intervention met with a pharmacist once during their second or third chemotherapy infusion. We obtained information about patients' medications and vaccinations via patient report and from the electronic health record (EHR) at baseline and week 4. We determined the number of discrepant (difference between patient report and EHR) and potentially inappropriate (Beers Criteria assessed by nonintervention pharmacists blinded to group assignment) medications. We defined the intervention as feasible if >75% of patients enrolled in the study and received the pharmacist visit. RESULTS: From January 17, 2017, to October 27, 2017, we enrolled and randomized 60 patients (80.1% of patients approached). Among those assigned to the intervention, 96.6% received the pharmacist visit. At week 4, intervention patients had higher rates of acquiring vaccinations for pneumonia (27.6% vs. 0.0%, p = .002) and influenza (27.6% vs. 0.0%, p = .002) compared with usual care. Intervention patients had fewer discrepant (5.82 vs. 8.07, p = .094) and potentially inappropriate (3.46 vs. 4.80, p = .069) medications at week 4, although differences were not significant. CONCLUSION: Integrating pharmacists into the care of older adults with cancer is feasible with encouraging preliminary efficacy for enhancing medication management and improving vaccination rates. IMPLICATIONS FOR PRACTICE: Results of this study showed the feasibility, acceptability, and preliminary efficacy of an intervention integrating pharmacists into the care of older adults with cancer. Notably, patients assigned to the intervention had fewer discrepant medications and were more likely to acquire vaccinations for pneumonia and influenza. Importantly, this work represents the first randomized controlled trial involving the integration of pharmacists into the outpatient oncologic care of older adults with cancer. In the future, a larger randomized trial is needed to demonstrate the efficacy of this care model to enhance medication management and improve vaccination outcomes for older patients with cancer.

Ribociclib for post-menopausal women with HR+/HER2- advanced or metastatic breast cancer.

INTRODUCTION: The introduction of CDK4/6 inhibitors, such as ribociclib, has changed the treatment landscape for post-menopausal women with HR+/HER2- advanced or metastatic breast cancer. As first-line treatment of HR+/HER2- MBC, the addition of a CDK4/6 inhibitor to an aromatase inhibitor improves progression-free survival compared to an aromatase inhibitor alone. Areas covered: In this drug profile, we review the current market for HR+/HER2- MBC, as well as the characteristics, mechanism, pharmacology, pharmacodynamics, pharmacokinetics, metabolism, clinical efficacy, toxicities, monitoring, and dosing modification of the CDK4/6 inhibitor ribociclib. Expert commentary: CDK4/6 inhibitors, such as ribociclib, improve outcomes in post-menopausal women with HR+/HER2- MBC. The most common toxicity of ribociclib is neutropenia, which is generally not complicated and can be managed with dose modification and/or supportive care measures. Additional research will help better define the optimal clinical use of ribociclib.

Prevention and Treatment of Cancer-Related Infections, Version 2.2016, NCCN Clinical Practice Guidelines in Oncology.

Infectious diseases are important causes of morbidity and mortality in patients with cancer. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Prevention and Treatment of Cancer-Related Infections characterize the major pathogens to which patients with cancer are susceptible, with a focus on the prevention, diagnosis, and treatment of major common and opportunistic infections. This portion of the guidelines highlights the sections on antifungal and antiviral prophylaxis. Antifungal and antiviral prophylaxis recommendations have expanded over the past few years. New agents for the treatment of fungal infections and incorporation of therapeutic drug monitoring are presented. Antiviral prophylaxis for hepatitis B and management considerations for hepatitis C and HIV have been further developed.

The national agenda for quality palliative care: promoting the National Consensus Project's domain of physical care and the National Quality Forum's preferred practices for physical aspects of care.

The National Consensus Project (NCP) 2004 Clinical Practice Guidelines for Quality Palliative Care defines eight domains of care essential for palliative care clinical practice. The National Quality Forum (NQF) 2006 document entitled A National Framework and Preferred Practices for Palliative and Hospice Care Quality: A Consensus Report is based on the NCP Guidelines. The NQF document identifies 38 evidence-based preferred practices for palliative care. This paper demonstrates how the Guidelines and Preferred Practices may be operationalized by pharmacotherapists to better treat symptoms of debilitating or chronic illnesses falling under Domain 2 of the Guidelines, "Physical Care." Specifically, dementia and dyspnea are used as illustrative examples.
