New antibody drug aims to halt Scleroderma's grip
NCT ID NCT05726630
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 3 trial tests whether the drug divozilimab can reduce skin thickening and protect lung function in people with systemic scleroderma, a rare autoimmune disease. About 152 adults and teens with active disease will receive either the drug or a placebo. The study is double-blind, meaning neither patients nor doctors know who gets what.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Divozilimab (a lab-made antibody that targets certain immune cells)
- What this could lead to
- If it works, this could offer a new treatment option to slow skin hardening and preserve lung function in people with systemic scleroderma.
- What could go wrong
- This is a Phase 3 trial, but results are not yet known. The drug may not improve symptoms better than placebo, and side effects from immune suppression are possible.
