New antibody drug targets autoimmune diseases in early trial
NCT ID NCT07229144
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase study tests a new drug called OM336 in 39 adults with active Sjogren's disease or idiopathic inflammatory myopathy who have not improved with at least two prior treatments. OM336 is an engineered antibody designed to target and potentially reduce harmful immune cells. The main goal is to check safety and how the drug moves through the body.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- OM336 (an engineered bispecific antibody targeting BCMA and CD3)
- What this could lead to
- If successful, this could point toward a new treatment option for people with active Sjogren's disease or idiopathic inflammatory myopathy who have not responded to other therapies.
- What could go wrong
- This is a very early (Phase 1b), small trial (39 participants) focused on safety and dosing. It is not designed to prove effectiveness, and many early-stage drugs do not advance.
