Apremilast was titrated from 10 mg QD to 30 mg BID over the first 5 days of dosing.2,4
Upon relapse (>50% loss of Week-24 PASI percentage improvement from baseline), patients were switched to SOTYKTU 6 mg QD; due to a programming error, however, these patients continued on placebo until Week 52.5
Study design1

At Week 16: ss-PGA score of 0 (clear) or 1 (almost clear)
Proportion of patients who achieved the following responses vs placebo
At Week 16: ss-PGA score of 0 (clear) or 1 (almost clear)
Statistical significance was not met for the following key secondary endpoints1,2,4
PGA-F 0/1 (PGA-F score of clear or minimal disease) vs placebo (BL ≥3) at Week 16, PSSD symptom score of 0 vs apremilast (BL ≥1) at Week 16
BID=twice daily; BL=baseline; BSA=body surface area; PASI 50=≥50% reduction from baseline in PASI; PASI 75=≥75% reduction from baseline PASI; PASI 90=≥90% reduction from baseline PASI; QD=once daily; sPGA=static Physician's Global Assessment; ss-PGA=scalp-specific Physician's Global Assessment; PGA-F=Physician's Global Assessment of Fingernail Psoriasis; PSSD=Psoriasis Symptoms and Signs Diary.
POETYK PSO-LTE:
Long-term extension study1-7
Apremilast was titrated from 10 mg QD to 30 mg BID over the first 5 days of dosing.2,4
Upon relapse (≥50% loss of Week 24 PASI percentage improvement from baseline), patients were switched to SOTYKTU 6 mg QD; due to a programming error, however, these patients continued on placebo until Week 52.5
Safety data through 3 years and efficacy data through 148 weeks. The cutoff date of June 15, 2022.7
Study design
Patients who completed treatment through Week 52 in either POETYK PSO-1 or PSO-2 were eligible to enroll in an optional LTE and be switched to open-label SOTYKTU 6 mg once daily5
A total of 1519 patients received ≥1 dose of SOTYKTU across the parent trials and the LTE including 1364 patients in PSO-1/PSO-2 and 1221 patients in the LTE5
Exposure during Weeks 0-52 of PSO-1/PSO-2 was 969.0 PY, with an additional 2325.3 PY of exposure during the LTE5,7‡
1178 (77.6%) patients had >12 months of total SOTYKTU exposure and 341 (22.4%) patients had >36 months of total SOTYKTU exposure throughout POETYK PSO-1, PSO-2, and PSO-LTE7
LTE=long-term extension; PY=patient-years.
