Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
This trial is testing a medication called to treat moderate to severe plaque psoriasis (a skin condition with thick, scaly patches). The main question is whether patients can stay healthy after taking this medication for just 6 months and then stopping it—rather than needing to take it forever. Researchers will also look at blood and skin samples to understand why some people do better than others.
Most treatments for severe psoriasis need to be taken long-term, which can be costly and may have side effects over time. This trial explores whether a shorter course of this medication could work just as well, helping patients achieve lasting improvement without continuous treatment.

If you join the treatment group, you'll receive injections of the medication starting with a larger dose, then smaller doses every 2 weeks for the first 3 months, and then monthly doses for 3 more months (6 months total). After that, the medication stops. Researchers will follow you for up to 2 years to see how your skin does, whether your psoriasis comes back, and how your quality of life is affected. You'll also have skin biopsies and blood tests taken to help scientists understand what happens in your body.
