Awareness, Knowledge, and Perceptions of Biosimilars Among Specialty Physicians

Area of Science:

• Pharmacoeconomics
• Drug Development
• Clinical Practice

Background:

• The increasing prevalence of biologic therapies necessitates understanding of biosimilars.
• Biosimilars offer potential for cost savings and increased patient access to complex medicines.
• Physician awareness and knowledge are critical for biosimilar adoption.

Purpose of the Study:

• To establish a baseline understanding of US physicians' knowledge and perceptions of biosimilars.
• To identify key areas where educational interventions are needed for prescribers of biologics.

Main Methods:

• A 19-question survey was developed by the Biosimilars Forum.
• An independent organization administered the survey to 1201 US physicians in high-prescribing specialties from November 20, 2015, to January 4, 2016.

Main Results:

• Significant knowledge gaps were identified across five key areas related to biosimilars.
• Physicians demonstrated limited understanding of biologic and biosimilar definitions, the approval process, and interchangeability.
• Awareness of biosimilar safety, immunogenicity, and indication extrapolation requires further evidence-based education.

Conclusions:

• There is a substantial need for targeted, evidence-based education on biosimilars for US physicians.
• Addressing these knowledge gaps is crucial for informed prescribing and appropriate utilization of biosimilars.
• Future surveys will monitor trends in physician knowledge and perceptions over time.
