title: The Current State of Dermatologists' Familiarity and Perspectives of Biosimilars for the Treatment of Psoriasis: A Global Cross-Sectional Survey.
abstract: <p>BACKGROUND: Biologic patent expiration, accelerated approval pathways, and business interests of third party payers and the biopharmaceutical industry are driving the development of biosimilars to treat immune-mediated disorders like psoriasis. No studies have investigated dermatologists' familiarity and perspectives of biosimilars.</p> <p>OBJECTIVES: To assess: (1) dermatologists' familiarity with biosimilars and interchangeability and (2) their perspectives toward biosimilar properties, including interchangeability, indication extrapolation, and immunogenicity risk.</p> <p>METHODS: For this prospective survey study, we distributed electronic and paper questionnaires to dermatologists from selected societies and attendees at the 73rd annual American Academy of Dermatology meeting between March 20, 2015 and May 30, 2015. Primary outcome was dermatologists' familiarity with biosimilars. Secondary aims included dermatologists' confidence in biosimilar efficacy and safety, familiarity concerning the concept of interchangeability and perspectives regarding indication extrapolation, interchangeability, and immunogenicity risk.</p> <p>RESULTS: Of the 116 total dermatologists who completed the questionnaire, 73 (62.9%) were slightly to very unfamiliar with biosimilars. On a 5-point Likert scale, dermatologists were somewhat to very concerned with the practice of interchangeability (3.4±1.1) and slightly uncomfortable to fairly comfortable in prescribing biosimilars for an extrapolated indication (3.3±1.0).</p> <p>CONCLSUIONS: Our survey identified that the majority of dermatologists were unfamiliar with biosimilars. Dermatologists were consistently concerned regarding safety issues surrounding the practice of interchangeability without provider knowledge.</p> <p><em>J Drugs Dermatol. 2017;16(4):336-343.</em></p>.
