Rituximab for treating immune-related side effects from checkpoint inhibitors

Official title: Rituximab for Treatment of Checkpoint Inhibitor Induced Immune-related Adverse Events

Run by Herlev Hospital · NCT07694414 · Data updated 2026-11-12

This small early-phase trial tests whether a single 100 mg dose of rituximab can help manage immune-related adverse events in adults with malignant melanoma who are on checkpoint inhibitors, alongside a tapering corticosteroid plan.

Is this trial a fit for you?

Likely a good fit

Adults (≥18) with melanoma treated with checkpoint inhibitors who have grade 2–4 irAEs and meet safety criteria.

Probably not a fit

Patients with infectious diseases, severe hematologic abnormalities, certain cardiovascular conditions, or immunosuppressive co-therapy may not benefit or could be at risk.

What this trial studies

This Phase 1 interventional study aims to assess the safety of a single 100 mg intravenous dose of rituximab in patients who develop immune-related adverse events while receiving checkpoint inhibitors for malignant melanoma. Participants will be followed for six months after infusion while continuing a corticosteroid taper. The trial will compare signals of clinical benefit against expectations from standard corticosteroid treatment alone, with regular follow-up visits to monitor safety and irAE outcomes. Eligible patients are adults with histologically confirmed melanoma, currently treated with anti-PD-1/PD-L1/CTLA-4/other agents, and experiencing irAEs of grade 2–4. Exclusion criteria include infectious diseases, significant hematologic abnormalities, certain cardiovascular conditions, low IgG, and active HIV/HBV/HCV or TB infection.

Why it matters

Potential benefit: If successful, rituximab could offer an alternative or adjunct to corticosteroids for managing irAEs in melanoma patients.

How similar studies have gone: Prior data in irAE management with rituximab are limited; this approach is exploratory for this indication.
