Acceptability of Cyltezo pen among biologics autoinjector patients, autoinjector naïve patients, and healthcare professionals.

Background: Cyltezo® (Adalimumab-adbm) is an FDA-approved interchangeable biosimilar for Humira® (adalimumab reference product [RP]) that helps treat chronic inflammatory conditions. Adalimumab-adbm is administered via an autoinjector, the adalimumab-adbm pen. This study assessed user opinions related to usability, perceptions, convenience, safety features, and acceptability of the adalimumab-adbm pen.

Methods: Ninety-eight Humira Pen users, 100 biologics pen naïve patients, and 99 healthcare professionals simulated the use of the adalimumab-adbm pen on injection pads. Opinions were captured with a validated questionnaire using Likert-type scales during moderated interviews. Binomial tests were conducted for top-two rating percentages.

Results: Nearly 90% of participants found the adalimumab-adbm pen 'easy' or 'very easy' to use, handle, and learn how to use. Almost 90% of volunteers thought the pen was 'very' or 'extremely' solid and convenient to use at home. Around 80% found the pen to be 'very' or 'extremely' comfortable. Over 90% of respondents said they would be 'satisfied' or 'very satisfied' with the safety features and the device itself. Nearly 90% of respondents indicated being 'very' or 'extremely' open to adopting the adalimumab-adbm pen.

Conclusions: The adalimumab-adbm pen provided users with a positive experience with features that benefit perceptions of usability, handling, safety, convenience, and acceptability.
