WEEK 16 CO-PRIMARY ENDPOINTS
POETYK PSO-1 (N=664) and POETYK PSO-2 (N=1020) were two, 52-week, multicenter, randomized, double-blind, placebo- and active (apremilast 30 mg twice daily)-controlled, Phase 3 studies to evaluate the safety and efficacy of SOTYKTU (6 mg once daily) in adult patients with moderate-to-severe plaque psoriasis who were eligible for systemic therapy or phototherapy. Patients had a body surface area (BSA) involvement of ≥10%, a Psoriasis Area and Severity Index (PASI) score ≥12, and a static Physician’s Global Assessment (sPGA) ≥3 (moderate or severe).

Data shown above are from PSO-LTE: pooled PSO-1 and PSO-2 through Week 208 (mNRI)1
LTE LIMITATION: In open-label LTEs, patients who lose response or are unable to tolerate treatment are likely to discontinue treatment, which may raise the proportion of responders in the overall population.
POETYK PSO-LTE is an ongoing, open-label, long-term extension trial that enrolled participants from the Phase 3 POETYK PSO-1 and PSO-2 trials. All patients in PSO-1 and PSO-2 were eligible to enter the LTE trial after 52 weeks of treatment, regardless of initial treatment. At the start of the LTE (Week 52), 1221 patients were blindly switched from SOTYKTU, apremilast, or placebo to open-label SOTYKTU 6 mg once daily. Primary endpoints are incidence of adverse events and serious adverse events. Key secondary endpoints are sPGA 0/1 and PASI 75.
Data is presented as an interim analysis with a data cutoff of November 1, 2023. Outcomes were analyzed descriptively.
