This survey assessed autoinjector attributes that are important to patients, and assessed patient perceptions and preferences between an adalimumab biosimilar autoinjector (Hyrimoz® SensoReady® Pen [SDZ-ADL pen]) and the reference adalimumab autoinjector (Humira® Pen [ref-ADL pen]) in patients with rheumatoid arthritis (RA) or Crohn’s disease (CD) in Canada.Patients and Methods: In this survey, adult patients were recruited for web-assisted telephone interviews. Patients had ≥ 3 months’ experience with the ref-ADL pen and 1– 12 months’ experience with the SDZ-ADL pen.Results: The survey included 120 patients with RA (n = 32) or CD (n = 88). Mean experience with the ref-ADL pen was 7 years for RA or 5 years for CD vs 9 months with the SDZ-ADL pen. The most important autoinjector attributes were the ability to use the pen independently and the ease and simplicity of self-injection. When comparing the two autoinjectors, patients significantly preferred the SDZ-ADL pen over the ref-ADL pen for nearly every attribute evaluated, with the greatest differences reported for visual and audible feedback mechanisms, ease of self-injection, and ability to use the device independently. Overall, 82% of patients preferred the SDZ-ADL pen over the ref-ADL pen, with buttonless activation and less injection pain being the main drivers for this preference.Conclusion: Patients with RA or CD indicated a preference for the SDZ-ADL pen over the ref-ADL pen, independent of the duration of use of the pen. The preference for a biosimilar device within 1 year of switching provides reassurance of rapid patient acceptance of biosimilars and may simplify the switching process. These results confirm the importance of ensuring autoinjector design supports independent self-administration of medication and align with previous data showing high patient satisfaction with the SDZ-ADL pen.Keywords: adalimumab, adherence, autoinjector, biosimilar, patient preference
