Background: The Biologics Price Competition and Innovation Act (BPCIA) of 2009, which included pathways for FDA approval of biosimilar products, was designed to promote more affordable, expanded patient access to biologic therapies. Achieving these BPCIA goals depends on overcoming formidable barriers to biosimilar adoption. Managed care and specialty pharmacy professionals are uniquely qualified to inform initiatives to address these barriers.
Objective: To assess perceptions regarding strategies for overcoming barriers to biosimilar adoption among managed care and specialty pharmacy professionals by conducting a survey study.
Methods: Invitations to complete the online survey were emailed by the Academy of Managed Care Pharmacy (AMCP) to members and customers and to contacts sourced from a commercial database. In addition to questions on respondent demographics and perceptions of biosimilars, the survey listed 16 strategies for overcoming key barriers to biosimilar adoption. On a 5-point scale, participants rated their opinion on the likelihood that each strategy would have the potential to assist in achieving BPCIA goals. The survey also listed 6 barriers to biosimilar adoption. On a 5-point scale, participants rated their perceived difficulty in overcoming each barrier. The survey concluded with an open-text item that asked participants to list 3 additional strategies for overcoming biosimilar adoption barriers. Response frequencies were calculated to describe participants' ratings of the strategies and barriers. Statistical analyses were conducted to assess whether the ratings differed among respondents grouped by work organization. For the open-text item, we conducted qualitative content analyses to categorize strategies by stakeholder groups that might take primary implementation roles.
Results: A total of 300 managed care and specialty pharmacy professionals completed the survey. There was considerable variation in the preferences, policies, and practices regarding biosimilar adoption among respondents' work organizations. Responses to several survey items reflected positive attitudes about the safety and efficacy of biosimilars; for example, 84% agreed or strongly agreed that FDA-approved biosimilars are safe and effective for patients who switch from a reference biologic. Based on pooled percentages for ratings of likely and extremely likely to overcome barriers to biosimilar adoption, the highest-rated strategies were for prescriber education about evidence from switching studies (91%) and FDA guidance on pharmacy-level substitution of reference biologics with biosimilars (90%). The lowest-rated strategies were for requiring therapeutic drug monitoring for patients who switch to biosimilars (39%) and using quotas to incentivize providers to prescribe biosimilars (40%). For the qualitative analysis, the highest numbers of respondents' suggested strategies indicated primary implementation roles of biosimilar manufacturers (40%), the federal government (26%), and managed care organizations (15%).
Conclusions: Reflecting the unique knowledge, perspectives, and practices of managed care and specialty pharmacy professionals, the study findings are relevant to informing and advancing initiatives for achieving BPCIA goals.
