BID=twice daily; BL=baseline; BSA=body surface area; PASI=Psoriasis Area and Severity Index; PASI 50=≥50% improvement from baseline in PASI; PASI 75=≥75% improvement from baseline in PASI; PASI 90=≥90% improvement from baseline in PASI; PGA-F=Physician’s Global Assessment of Fingernail Psoriasis; PSSD=Psoriasis Symptoms and Signs Diary; QD=once daily; sPGA=static Physician’s Global Assessment; sPGA 0/1=static Physician’s Global Assessment, patients achieving clear (0) or almost clear (1) skin; ss-PGA=scalp-specific Physician’s Global Assessment.
POETYK PSO-LTE:
Long-term extension study1-3,8
| * | Otezla was titrated from 10 mg QD to 30 mg BID over the first 5 days of dosing.3 |
| † | 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 52.3 |
| ‡ | Safety and efficacy data through 256 weeks with a cutoff date of September 2, 2024.3 |
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 daily2
- A total of 1,519 patients received ≥1 dose of SOTYKTU across the parent trials and the LTE including 1,364 patients in PSO-1/PSO-2 and 1,221 patients in the LTE2
- Exposure during Weeks 0-52 of PSO-1/PSO-2 was 969.0 PY, with an additional 4,077.7 PY of exposure during the LTE3,8
- 1,206 (79.4%) patients had ≥12 months of total SOTYKTU exposure and 449 (29.6%) patients had ≥60 months of total SOTYKTU exposure throughout POETYK PSO-1, PSO-2, and PSO-LTE3
