Summary

This trial assesses the effectiveness of a drug for adults with moderate-severe plaque psoriasis. 7 visits over 12 weeks + 2 wks follow-up. Double-blind, placebo-controlled.

Who is the study for?
Adults with moderate to severe plaque psoriasis can join this trial. They should have a Psoriasis Area and Severity Index (PASI) score of at least 12, a static Physician's Global Assessment (sPGA) score of at least 3, and body surface area (BSA) affected by psoriasis must be 10% or more. Candidates must weigh over 50 kg with a BMI between 18-35 and be suitable for phototherapy or systemic therapy.
What is being tested?
The study is testing SAR441566 against a placebo in adults with plaque psoriasis. It's randomized, meaning people are put into the treatment or placebo group by chance, double-blind so neither participants nor researchers know who gets what during the study, and it lasts for about three months plus follow-ups.
What are the potential side effects?
While specific side effects aren't listed here, typical ones from treatments like SAR441566 may include reactions at the injection site, cold symptoms, headache, fatigue, stomach issues and potential risks to liver health.
