Real-World Use of Fedratinib for Myelofibrosis Following Prior Ruxolitinib Failure: Patient Characteristics, Treatment Patterns, and Clinical Outcomes.

BACKGROUND: There is a lack of established clinical outcomes for patients with myelofibrosis (MF) receiving fedratinib following ruxolitinib failure. This study examined real-world patient characteristics, treatment patterns, and clinical outcomes of patients with MF treated with fedratinib following ruxolitinib failure in US clinical practice. PATIENTS AND METHODS: This retrospective patient chart review included adults with a physician-reported diagnosis of MF, who initiated fedratinib after discontinuing ruxolitinib. Descriptive analyses characterized patient characteristics, clinical outcomes, and treatment patterns from MF diagnosis through ruxolitinib and fedratinib treatment. RESULTS: Twenty-four physicians abstracted data for 150 eligible patients. Approximately 55.3% of the patients were male, 68.0% were White, and median age at MF diagnosis was 68 (range, 35-84) years. Median duration of ruxolitinib therapy was 7.6 (range, 0.7-65.5) months. At initiation of fedratinib, 88.0% of patients had palpable spleen and a mean spleen size of 16.0 (standard deviation [SD], 5.9) cm. Spleen size decreased by 19.4% to 13.2 (SD, 7.9) cm at month 3 (P = .0001) and by 53.4% to 7.2 (SD, 7.4) cm at month 6 (P = .01) of fedratinib treatment, respectively. Almost one-third (26.8%) of patients had achieved ≥ 50% spleen reduction by month 6. Mean number of symptoms also decreased significantly at month 3 (P < .0001) and month 6 (P = .01). CONCLUSION: Fedratinib appears to deliver spleen and symptom benefits in real-world patients with MF previously treated with ruxolitinib.

Better together? costs of first-line chemoimmunotherapy for advanced non-small cell lung cancer.

OBJECTIVES: Recent advances have created options for first-line (1L) treatment of advanced/metastatic non-small cell lung cancer (aNSCLC). The study objectives were to describe the utilization of 3 classes of 1L treatment-chemotherapy (CT), immunotherapy (IO), and chemoimmunotherapy (IO+CT)-and the total, third-party payer, direct health care costs. STUDY DESIGN: Retrospective, administrative claims database analysis of patients with aNSCLC who initiated 1L treatment between January 1, 2017, and May 31, 2019, with IO, CT, or IO+CT. METHODS: Microcosting enumerated health care resource utilization, including antineoplastic drug costs, using standardized costs. Generalized linear models estimated per-patient per-month (PPPM) costs during 1L treatment, and adjusted cost differences in 1L among treatment cohorts were calculated using recycled predictions. RESULTS: A total of 1317 IO-, 5315 CT-, and 1522 IO+CT-treated patients were identified. Utilization of CT declined from 72.3% to 47.6% between 2017 and 2019, replaced by use of IO+CT, which increased from 1.8% to 29.8%. Total PPPM costs in 1L were highest with IO+CT at $32,436, compared with $19,000 and $17,763 in the CT and IO cohorts, respectively. Adjusted analyses showed that PPPM costs were $13,933 (95% CI, $11,760-$16,105) higher in the IO+CT vs IO cohort (P < .001) and IO costs were $1024 (95% CI, $67-$1980) lower than CT (P = .04). CONCLUSIONS: IO+CT accounts for almost one-third of 1L aNSCLC treatment modalities, coinciding with a reduction in treatment with CT. Costs for patients treated with IO were lower than those for patients treated with both IO+CT and CT alone, driven primarily by antineoplastic drug and associated medical costs.

Effectiveness of Eribulin in Metastatic Breast Cancer: 10 Years of Real-World Clinical Experience in the United States.

INTRODUCTION: Eribulin was approved in the United States (US) in 2010 for patients with metastatic breast cancer (MBC) who previously received at least two chemotherapeutic regimens, including anthracycline and taxane in the adjuvant or metastatic setting. With significant changes to the treatment landscape over the past decade, assessment of the real-world effectiveness of eribulin in clinical practice when used according to the approved US indication is valuable. METHODS: Patients with MBC were identified by community oncologists through a retrospective, multi-site patient chart review; de-identified data were abstracted into electronic case report forms. Eligible patients initiated eribulin consistent with approved US indication between 1 January 2011 and 31 December 2017. Clinical outcomes assessed included objective response rate (ORR), progression-free survival (PFS) and overall survival (OS) in all patients and those with triple negative breast cancer (TNBC). RESULTS: The analysis included 513 patients (median 59.0 years; 38.8% with Eastern Cooperative Oncology Group status ≥ 2). Eribulin was third-line therapy for 78.0% of patients, and fourth-line or later for the remainder. ORR was 54.4%, median PFS was 6.1 months (95% CI: 5.8, 6.6), and median OS was 10.6 months (95% CI 9.9, 11.7) in all patients. Among the 49.9% of patients with TNBC, ORR was 55.1%, median PFS was 5.8 months (95% CI 5.1, 6.4), and median OS was 9.8 months (95% CI 8.6, 11.0). CONCLUSION: The current retrospective chart review study reinforces the clinical effectiveness of eribulin in patients with MBC, including those with TNBC, when used according to the approved US indication in real-world clinical practice.

Lenvatinib and Subsequent Therapy for Radioactive Iodine-Refractory Differentiated Thyroid Cancer: A Real-World Study of Clinical Effectiveness in the United States.

INTRODUCTION: Lenvatinib has become the most commonly prescribed first-line (1L) agent for the treatment of radioactive iodine-refractory differentiated thyroid cancer (RAI-r DTC) since its approval in 2015. With no real-world studies describing clinical outcomes of 1L lenvatinib and subsequent therapy, the current study aimed to assess treatment sequencing and related clinical outcomes in patients treated with 1L lenvatinib in the USA METHODS: We conducted a multisite, retrospective chart review of US patients with a diagnosis of RAI-r DTC who had initiated 1L therapy with lenvatinib from January 1, 2016 through May 31, 2017 with follow-up through October 17, 2018. Physicians completed electronic case report forms for two patient cohorts: patients still receiving 1L lenvatinib (cohort 1) and those who had initiated second-line (2L) therapy prior to data cutoff (cohort 2). Real-world objective response rate (ORR) was assessed for both cohorts. Progression-free survival (PFS) and overall survival (OS) were assessed for cohort 2. RESULTS: A total of 252 patients met the study criteria with 71 in cohort 1 and 181 in cohort 2. Patients were predominantly female, had papillary DTC, and had lung metastases. The ORR was 64.8% for cohort 1 and 53.6% for cohort 2. In cohort 2, median PFS from 1L lenvatinib initiation was 14.0 months (95% CI 12.7-15.0). Second-line treatments included sorafenib (49.7%), cabozantinib (19.3%), and other targeted/chemotherapy/immuno-oncology agents. The ORR in 2L therapy was 15.5%. For cohort 2, the 12-, 18-, and 24-month OS from initiation of 1L lenvatinib was 92.8%, 81.5%, and 66.9%, respectively. CONCLUSIONS: In this first real-world examination of clinical effectiveness of 1L lenvatinib and subsequent therapy among patients in the US, the results demonstrated that treatment with 1L lenvatinib followed by another 2L therapy may deliver a clinical benefit, thus allowing a number of potential 2L options following 1L lenvatinib for patients with RAI-r DTC.

Frequency and Causes of Burnout in US Community Oncologists in the Era of Electronic Health Records.

BACKGROUND: Physician burnout, characterized by exhaustion of physical or emotional strength, cynicism, and lack of achievement, has become a worsening phenomenon in medicine, contributing to higher health care costs and patient/physician dissatisfaction. How burnout has affected hematologists and oncologists is not well studied. METHODS: US community oncologists/hematologists were queried via a Web-based survey from September-November 2018. Physicians were asked about frequency of burnout symptoms, drivers of work-related stress, and their perceptions on management of workload. RESULTS: Among the 163 physicians surveyed, 46% felt a substantial amount of stress at work. Most physicians felt emotionally (85%) and physically (87%) exhausted. A majority of physicians felt lethargic (67%), ineffective (64%), and/or detached (63%). In a typical workweek, 93% needed time beyond time allocated to clinical care to complete work responsibilities. Electronic health record (EHR) responsibilities caused moderate to excessive stress at work for 67% of physicians; 79% of physicians worked on EHRs outside of clinic hours. Other sources of excessive stress were changing reimbursement models (33%), interactions with payers (31%), and increasing patient and caregiver demands (31%). A third of physicians have considered retiring early or changing their career path to cope. To combat burnout, physicians' practices have used advanced practice providers, invested in information technology, and/or hired additional administrative staff. However, the majority of physicians stated they had optimal or good control over their workload. CONCLUSION: Most oncologists experience burnout symptoms and require additional time beyond that allocated to clinical care to complete their workload. The discordance between oncologists' admission of stress and exhaustion while claiming good control over those same burdens warrants exploration in future research.

Observational study of clinical outcomes of eribulin mesylate in metastatic breast cancer after cyclin-dependent kinase 4/6 inhibitor therapy.

Aim: To examine the effectiveness of eribulin mesylate for metastatic breast cancer post cyclin-dependent kinase inhibitor (CDKi) 4/6 therapy. Materials & methods: US community oncologists reviewed charts of patients who had received eribulin from 3 February 2015 to 31 December 2017 after prior CDKi 4/6 therapy and detailed their clinical/treatment history, clinical outcomes (lesion measurements, progression, death) and toxicity. Results: Four patient cohorts were created according to eribulin line of therapy: second line, third line, per US label and fourth line with objective response rates/clinical benefit rates of 42.2%/58.7%, 26.1%/42.3%, 26.7%/54.1% and 17.9%/46.4%, respectively. Median progression-free survival/6-month progression-free survival (79.5% of all patients censored) by cohort was: 9.7 months/77.3%, 10.3 months/71.3%, not reached/70.4% and 4.0 months/0.0%, respectively. Overall occurrence of neutropenia = 23.5%, febrile neutropenia = 1.3%, peripheral neuropathy = 10.1% and diarrhea = 11.1%. Conclusion: Clinical outcome and adverse event rates were similar to those in clinical trials and other observational studies. Longer follow-up is required to confirm these findings.

High Triglycerides Are Associated With Increased Cardiovascular Events, Medical Costs, and Resource Use: A Real-World Administrative Claims Analysis of Statin-Treated Patients With High Residual Cardiovascular Risk.

Background The American Heart Association recognizes high triglycerides as a cardiovascular risk factor. Methods and Results This retrospective observational administrative claims analysis (Optum Research Database) included statin-treated patients ≥45 years old with diabetes mellitus and/or atherosclerotic cardiovascular disease, triglycerides 2.26 to 5.64 mmol/L, and a propensity-matched comparator cohort with triglycerides <1.69 mmol/L and high-density lipoprotein cholesterol >1.04 mmol/L. In the high-triglycerides cohort versus comparators (both n=10 990, 49% women), mean age was 61.7 versus 62.2 years and follow-up was 41.3 versus 42.1 months, respectively. Multivariate analysis of composite major cardiovascular events demonstrated significantly increased risk in the high-triglycerides (n=13 411 patients) versus comparator (n=32 506 patients) cohorts (hazard ratio [ HR ], 1.35; 95% confidence interval [ CI ], 1.225-1.485; P<0.001), with significantly higher risk for nonfatal myocardial infarction ( HR , 1.35; 95% CI , 1.19-1.52; P<0.001), nonfatal stroke ( HR , 1.27; 95% CI , 1.14-1.42; P<0.001), and need for coronary revascularization ( HR , 1.51; 95% CI , 1.34-1.69; P<0.001), but not unstable angina or cardiovascular death. Increased cardiovascular risk in the high-triglycerides versus comparator cohort was maintained, even with addition of non-high-density lipoprotein cholesterol to the multivariate model and when analyzing high and low high-density lipoprotein cholesterol subgroups. Average total healthcare cost per patient per month (cost ratio, 1.15; 95% CI , 1.084-1.210; P<0.001) and rate of occurrence of inpatient hospital stay ( HR , 1.17; 95% CI , 1.113-1.223; P<0.001) were also significantly greater in the high-triglycerides cohort. Conclusions In this real-world analysis, patients with high cardiovascular risk and high triglycerides had worse composite cardiovascular and health economic outcomes than patients with well-managed triglycerides and high-density lipoprotein cholesterol >1.04 mmol/L.
