Researchers are conducting a multicenter, randomized, double-blinded, placebo-controlled study to find the best dose of ORKA-002 for adults with moderate-to-severe plaque psoriasis. The study aims to evaluate the effectiveness and safety of ORKA-002 compared to a placebo. Approximately 160 adult participants diagnosed with plaque psoriasis for more than 6 months, who are candidates for systemic therapy or phototherapy, will take part in this Phase 2 trial. Participants will receive one of three induction dosing regimens of ORKA-002 or a placebo, both administered by subcutaneous injection. The study consists of three periods: a screening period, an induction period where treatment is given, and a post-treatment follow-up period to monitor outcomes and safety. The goal is to identify the optimal dosing regimen that provides the best balance of efficacy and safety. During the study, participants will be assessed for the proportion achieving complete clearance of psoriasis skin symptoms (100% reduction in PASI score) by week 16. Researchers will also monitor for any treatment-emergent adverse events or serious side effects through week 48. Participants will undergo various evaluations including clinical assessments and safety monitoring throughout the study duration.
