Effectiveness and Safety of Secukinumab in Latin American Patients with Moderate to Severe Plaque Psoriasis: PURE Registry 12-Month Data

Background The efficacy and safety of secukinumab in patients with psoriasis has been established in randomised clinical trials. However, data on effectiveness and safety of secukinumab in Latin American real-world settings are scarce. Objectives To evaluate the effectiveness and safety of secukinumab in real-world settings in patients with psoriasis in Latin America. Methods PURE is an ongoing multinational, prospective, observational study in patients with moderate-to-severe chronic plaque psoriasis in Canada and Latin America assessing the real-world safety and effectiveness of secukinumab and other approved therapies. The study enrolled (1:1) patients treated with secukinumab versus other approved therapies (other Tx) per local standard of care from 81 community- and hospital-based speciality sites (21 in Latin America). Here, we report effectiveness and safety outcomes with secukinumab and other Tx for plaque psoriasis for up to 12 months in a Latin American population. Results Overall, 187 patients were included in the analysis, 89 of whom initiated secukinumab treatment and 98 of whom received other Tx. At month 12, 84.4%, 71.1% and 53.3% of patients treated with secukinumab achieved Psoriasis Area and Severity Index (PASI) 75/90/100, respectively, compared with 66.7%, 47.9% and 29.2% of patients who received other Tx. Investigator Global Assessment (IGA) 0/1 responders in secukinumab versus other Tx were 78.3% versus 36.7% at month 3 and 81.8% versus 66.7% at month 12, respectively. Overall, the proportion of patients achieving Dermatology Life Quality Index (DLQI) 0/1 improved from 6.9% at baseline to 76.5% at month 12 in patients treated with secukinumab versus 5.6% at baseline to 54.5% at month 12 in patients on other Tx. No unexpected adverse events were reported during the 12-month observation period. Conclusion Secukinumab demonstrated real-world effectiveness and improved dermatology quality-of-life in chronic plaque psoriasis patients from Latin America. Trial Registration PURE: NCT02786186.
