Healthcare Professional (HCP) and Patient Usability Evaluation and Preferences of Two Auto-injector Devices for Self-Injection of Biosimilars, SB4 and SB5: A Literature Review.

The analyzed data on usability and device preference indicate that SB4/Pen and SB5/Pen were preferred over the other reference product autoinjectors, thanks to their button-free design, auditory and visual injection feedback, and overall ease of use. Therefore, they were preferred over the other reference product autoinjectors. Because user-friendly devices can improve treatment adherence, pharmaceutical companies should consider patient convenience when developing medical devices.
