A Study Evaluating the Prophylactic Use of Tocilizumab to Prevent Cytokine Release Syndrome With Ramantamig Administration in Participants With Relapsed/Refractory Multiple Myeloma (TRI Pro)

June 8, 2026 updated by: Janssen Research & Development, LLC

79635322MMY2002: Phase 2 Randomized, Double-blind, Placebo-controlled Study Evaluating the Prophylactic Use of Tocilizumab to Prevent Cytokine Release Syndrome With Ramantamig Administration in Participants With Relapsed/Refractory Multiple Myeloma

The purpose of this study is to find out whether giving a single dose of tocilizumab before treatment with ramantamig can help prevent or reduce the severity of cytokine release syndrome (CRS) within 28 days from ramantamig, compared to participants who receive placebo. CRS is an acute inflammatory reaction that can occur during treatment and may be associated with flu-like or other systemic symptoms, such as fever and tiredness.
