Use of Apremilast® in the psoriasis treatment: a real-life multicenter Italian experience.

Abstract

Apremilast® (Amgen, Thousand Oaks, CA, USA) is the first small molecule approved for the treatment of moderate-to-severe psoriasis in adult patients; however, real-life data are still limited. We investigated the effectiveness and safety of this drug in a multicenter real-world setting. We retrospectively reviewed data from all psoriatic patients who received at least one dose of Apremilast® (Amgen) and collected demographic data and medical history at baseline and periodically for 36 months. A total of 111 patients entered in the study. The mean drug survival duration was 21.8±10.6 months; however, it was significantly shorter when comorbidities were ≥3 and if biologic drugs were previously administered. ΔPASI90 was achieved in 29% of patients and ΔPASI50 in 68% at T4; the rate of ΔPASI improvement increased progressively at T12, T24, T36 in patients who continued to receive Apremilast® (Amgen). At the end of the study 50 patients discontinued the treatment because of adverse events (19.8%), primary failure (19%) or secondary failure (6.3%). Apremilast® (Amgen) proved to be an effective, safe, and manageable drug, showing effectiveness also in difficult-to-treat patients with psoriasis, with a favorable tolerability profile and a potentially valid weight loss effect. We believe that treating patients with few comorbidities who are naive to biological therapy may result in higher response rates and longer mean drug survival.
