Could an immune drug ease schizophrenia symptoms?
NCT ID NCT07680946
First seen Jul 02, 2026 · Last updated Aug 27, 2026 · Updated 4 times
Summary
This phase 2 trial tests whether ublituximab, an immune-modulating drug, can reduce symptoms in people with treatment-resistant schizophrenia. Participants receive the drug by IV infusion, and researchers measure changes in symptom scores over time. The goal is to see if targeting the immune system might help when standard antipsychotics fail.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ublituximab (also known as BRIUMVI)
- What this could lead to
- If successful, this could point toward a new treatment option for people with schizophrenia who do not respond to standard antipsychotics.
- What could go wrong
- This is an early phase 2 trial with only 60 participants, so results may not apply to everyone. The drug may cause infusion reactions or infections, and its effect on schizophrenia symptoms is unproven.
