Weight-Loss drug tirzepatide could double as psoriasis treatment in new trial
NCT ID NCT06857942
First seen Jun 25, 2026 · Last updated Sep 04, 2026 · Updated 2 times
Summary
This study is testing whether adding the weight-loss drug tirzepatide to the standard psoriasis medication ixekizumab helps people with moderate-to-severe plaque psoriasis who are also overweight or obese. About 200 adults will receive tirzepatide injections for up to 12 months. Researchers will measure improvements in skin clearance, quality of life, and weight reduction.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tirzepatide
- What this could lead to
- If successful, adding tirzepatide to standard psoriasis therapy could help people with psoriasis and excess weight achieve clearer skin and significant weight loss.
- What could go wrong
- This is an early-phase, open-label study with no placebo group, so results may be less reliable. Tirzepatide can cause gastrointestinal side effects, and not all participants may respond.
