Beinfeld, McKenna, Rind, and Pearson are employed by ICER. Touchette received funding from ICER for work on this report and has also received fees from Monument Analytics and AstraZeneca, unrelated to this work. The University of Illinois at Chicago (UIC) and Touchette hold a patent for the model described in this report. The model is included in ICER's Interactive Modeler, for which a fee is paid to UIC and Touchette. Atlas also received funding from ICER for work on this report.BACKGROUND Traditionally, treatment for chronic conditions addressed symptoms or was disease modifying and required lifelong periodic administration and recurring costs. Cell and gene therapies for rare diseases often require a short administration period relative to their expected long-term clinical benefit. Costs have historically been recognized when the service or treatment is administered, resulting in the potential for the cost associated with the possible long-term clinical benefit of cell and gene therapies being incurred during a short administration period. Innovative payment arrangements have been proposed to improve the synchronization of the payment and the emergence of the clinical benefit. Expected payments associated with a multiyear payment arrangement will depend on many factors, but key drivers of the payments include efficacy, durability of effect, mortality, and member retention. This research extends a previous study by analyzing member retention for adult patients with certain rare diseember cohorts. Health insurers and plan administrators may have inaccurate expectations if standard assumptions based on all member populations are used. This study found that adults diagnosed with 1 of 7 rare medical conditions are retained longer, on average, than all adult subscribers. DISCLOSURES Milliman received funding from bluebird bio for the conduct of this study and fees from AveXis, outside the submitted work. Jackson, Runyan, and Metz are employed by Milliman. Jackson and Metz are members of the American Academy of Actuaries and meet the qualification standards for performing the analyses in this report. Kenney is an independent managed care consultant and received consulting fees from Milliman during the conduct of this study; Kenney also serves as preceptor for the Massachusetts College of Pharmacy and Health Sciences, is immediate past president of the Academy of Managed Care Pharmacy, and is a member of the Massachusetts Pharmacists Association Legislative Committee.BACKGROUND Age-related macular degeneration (AMD) is a leading cause of blindness worldwide and is the most common cause of blindness in developed countries. Despite antivascular endothelial growth factor (anti-VEGF) therapy demonstrating improvements in visual and anatomical outcomes, unmet needs remain. Brolucizumab-dbll (ie, brolucizumab), a VEGF inhibitor for treatment of neovascular (wet) AMD and recently approved by the FDA for its treatment of wet AMD, attempts to mitigate treatment burden through less frequent injections. OBJECTIVE To assess the incremental cost-effectiveness of brolucizumab compared with aflibercept and ranibizumab, given similar costs per injection and the potential for longer dosing intervals based on phase 3 clinical trial data. METHODS A Markov model was developed to model the treatment of wet AMD patients with brolucizumab vs aflibercept and vs ranibizumab over a lifetime time horizon (base case) and 5-year time horizon (scenario analysis). The Markov model consisted of 3 primardiak Sciences, NGM Biopharmaceuticals, Novartis, Opthea, Recens Medical, Regenxbio, Roche, and Regeneron, unrelated to this work. This research was presented as a virtual poster at the AMCP 2020 Annual Meeting, April 2020.BACKGROUND There is concern that increasingly common use of patient assistance programs (PAPs), out-of-pocket assistance provided by manufacturers or foundations, distorts our understanding of patient behavior and insurance design incentives. Yet the current literature on prescription drug cost sharing largely overlooks their use. PAPs prevalence and impact on drug demand and price elasticity is a major knowledge gap. OBJECTIVE To examine the use of PAPs among patients with multiple sclerosis (MS) and the association with drug demand in a specialty pharmacy program within a regional integrated health system that facilitates their use. METHODS We used pharmaceutical claims data from December 2017 to December 2018 linked to detailed payer information from Kaiser Permanente Washington to characterize the prevalence of PAPs for users of 7 MS specialty drug molecules. We estimated price elasticity of demand (PED) in a two-part model by using the presence of copayment assistance as a source of cost variation. The first part estimated marginal probability of a claim in a given month with a probit model, comparing PAP users and nonusers, whereas the second part estimated days supplied of a medication, given a claim was made as a measure for demand.
