BACKGROUND:Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9is) are an innovative treatment option for patients with familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease who require further lowering of low-density lipoprotein cholesterol. However, the high costs of these agents have spurred payers to implement utilization management policies to ensure appropriate use. We examined prior authorization (PA) requirements for PCSK9is across private and public US payers.
METHODS AND RESULTS:We conducted an analysis of 2016 formulary coverage and PA data from a large, proprietary database with information on policies governing >95% of Americans with prescription drug coverage (275.3 million lives) within 3872 plans across the 4 major insurance segments (commercial, health insurance exchange, Medicare, and Medicaid). The key measures included administrative PA criteria (prescriber specialty, number of criteria in PA policy or number of fields on PA form, requirements for medical record submission, reauthorization requirements) and clinical/diagnostic PA criteria (approved conditions, required laboratories or other tests, required concomitant therapy, step therapy requirements, continuation criteria) for each of 2 Food and Drug Administration-approved PCSK9is. Select measures (eg, number of PA criteria/fields, medical record submission requirements) were obtained for 2 comparator cardiometabolic drugs (ezetimibe and liraglutide). Between 82% and 97% of individuals were enrolled in plans implementing PA for PCSK9is (depending on insurance segment), and one third to two thirds of these enrollees faced PAs restricting PCSK9i prescribing to a specialist. For patients with familial hypercholesterolemia, diagnostic confirmation via genetic testing or meeting minimum clinical scores/criteria was also required. PA requirements were more extensive for PCSK9is as compared with the other cardiometabolic drugs (ie, contained 3×-11× the number of PA criteria or fields on PA forms and more frequently involved the submission of medical records as supporting documentation).
CONCLUSIONS:PA requirements for PCSK9is are greater than for selected other drugs within the cardiometabolic disease area, raising concerns about whether payer policies to discourage inappropriate use may also be restricting access to these drugs in patients who need them.
BACKGROUND: Few studies have examined oral anticancer treatment utilization patterns among Medicare beneficiaries.
OBJECTIVE:To assess treatment utilization patterns of newly initiated oral anticancer agents across national samples of Medicare beneficiaries for 5 cancer types: chronic myeloid leukemia (CML), multiple myeloma (MM), metastatic prostate cancer (mPC), metastatic renal cell carcinoma (mRCC), and metastatic breast cancer (mBC).
METHODS:This retrospective claims analysis used 100% Medicare Chronic Condition Data Warehouse (CCW) Parts A, B, and D files from 2011 to 2014 (for CML, MM, mPC, and mRCC patients) and a 5% random fee-for-service sample from 2011 to 2013 (for mBC patients).Outcomes of interest were the number of 30-day supply prescriptions, adherence, and discontinuation of newly initiated (ie, index) oral anticancer agents indicated for each of the cancers. Adherence was calculated with both the "traditional" proportion of days covered (PDC) approach, measured over a fixed
Chimeric antigen receptor T cells are a potentially curative new therapeutic option, but access challenges remain. The limited number of certified treatment centers and the need to travel to these centers, the expenses of travel and lodging and the out-of-pocket costs associated with treatment pose a challenge for patients. Further, the logistics of follow-up coupled with an ad hoc reimbursement environment make chimeric antigen receptor T-cell treatment an unattractive proposition for many providers. The patient-specific nature of these gene therapies has made scaling up production difficult for manufacturers. Providing expanded financial assistance for patients and education for community oncologists, and addressing reimbursement challenges, can alleviate some of these access barriers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
