Patient preference after switching guselkumab from prefilled syringe to an autoinjection pen in psoriasis and psoriatic arthritis patients.

Background: We assessed pain, acceptability, patient preference, and tolerability of patients with psoriasis and psoriatic arthritis after switching guselkumab from a prefilled syringe to One-Press autoinjector pen.

Methods: Patients with psoriasis and psoriatic arthritis treated for at least 6 months with guselkumab syringe were recruited from January 2019 to December 2022. Gender, age, diagnosis, self-administration and pain perception of guselkumab prefilled syringe were recorded. At the first visit patients completed a post-auto-injection syringe questionnaire before starting auto-injection pen administration. After 2 and 6 months of guselkumab self-injection using the One-Press autoinjector pen, patient experience, adherence, preference, pain and safety of each administration were assessed using post-guselkumab by One-Press autoinjector pen questionnaire.

Results: 40 patients (psoriasis n = 34, psoriatic arthritis n = 6) were included. All patients self-administered guselkumab by One-Press autoinjector pen. Pain at the injection site was significantly reduced with the use of the One-Press autoinjector pen. All patients considered that using One-Press autoinjector pen was easier than the syringe, 98% chose the pen as their preferred delivery system.

Conclusion: The One-Press autoinjector pen for guselkumab administration is presented as a preferred option, with a high satisfaction and less painful compared to the administration of guselkumab in a prefilled syringe.
