AB0761 SECUKINUMAB FOR THE TREATMENT OF PSORIATIC ARTHRITIS IN REAL LIFE: AN ITALIAN EXPERIENCE

Background: Secukinumab is a novel treatment for psoriatic arthritis (PsA) but data from real life are still missing. Objectives: The aim of this study is to evaluate a wide cohort of PsA patients on secukinumab followed in 7 Italian rheumatologic centers. Methods: Two-hundred and seventy-nine patients affected by PsA and on secukinumab were enrolled. Data on disease characteristics, previous and ongoing treatments, comorbidities and duration of follow-up were collected. In particular DAPSA and aSDAS were used to assess articular and axial disease activity. Results: Mean age of our cohort was 53±11 years and BMI 26.4±5.1 kg\m2 with the majority of patients being female (63.8%). Mean disease duration was 9.7±7.5 years and mean follow-up was 10.9±6.8 years. For 100 patients (35.8%) secukinumab was their first line biologic treatment and 41 (50.5%) were in monotherapy. DAPSA was 25.9±10.5 at baseline, 15.9±9.7 at M3, 12.9±8.4 at M6, 9.8±7.1 at M12 with a significant downward decrease at every visit as compared to baseline (p Forty patients (14.3%) stopped the treatment during the follow up mainly because of primary or secondary loss of efficacy (18 and 10, respectively). Only 9 patients suspended the treatment because of adverse events, of which 5 because of reactions at site of injection. The retention rate at 12 months was very good in the whole population (figure), and in particular in patients with entesitis at the baseline (10.5 vs, 11.2, p=0.038). No differences in survival were found when dividing patients accordingly to BMI, although overweight or obese patients showed a trend for a better retention rate (10.6 vs 10.9, p=0.089). Interestingly no differences were found between naive and non-naive patients (p=0.895) and between those in monotherapy or in combination therapy (p=0.925). Conclusion: This is one of the first real life studies on secukinumab and shows a very good efficacy and safety of this treatment in PsA patients, also for the articular manifestations, as shown by a significant decrease of DAPSA over a 12-months follow up.
