Could a single rituximab infusion tame Immunotherapy's harsh side effects?
NCT ID NCT07694414
First seen Jul 10, 2026 · Last updated Jul 23, 2026 · Updated 2 times
Summary
This trial investigates whether a single ultra-low dose of rituximab can safely manage immune-related side effects caused by checkpoint inhibitor therapy in people with malignant melanoma. Participants receive one 100 mg infusion of rituximab along with a steroid tapering plan and are followed for six months. The study focuses on safety and whether rituximab helps control symptoms better than steroids alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- rituximab
- What this could lead to
- If successful, this could offer a safer, faster way to control severe immune side effects from cancer immunotherapy, reducing reliance on steroids.
- What could go wrong
- This is a small early-phase trial, so results may not apply broadly. Rituximab carries risks like infusion reactions and increased infection risk.
