Exploration of Efficacy and Safety of Adjunctive Methylene Blue in the Treatment of Immunotherapy-related CRS and ICANS: A Prospective, Single-arm, Phase I Clinical Study

Institute of Hematology & Blood Diseases Hospital, China·interventional·Posted Sep 11, 2025·Updated Sep 11, 2025

In Brief

A Phase 1 clinical trial evaluating Methylene Blue for Cytokine Release Syndrome and ICANS. Currently recruiting, targeting 18 participants across 1 site.

Detailed Summary

This Phase I, prospective, single-arm clinical study aims to evaluate the efficacy and safety of adjunctive methylene blue (MB) in patients experiencing cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome (ICANS) following CAR-T cell therapy or bispecific antibody treatment. Preclinical studies demonstrated that MB alleviates CRS/ICANS-related symptoms, preserves the antitumor function of T cells, and modulates neuroinflammation without compromising immune efficacy. The study will employ a 3+3 dose-escalation design with three MB dosing cohorts, with treatment administered intravenously for 3-5 consecutive days. Vital signs, laboratory markers, and neurological status will be closely monitored, and concomitant standard supportive therapies will be permitted.

Interventions

Methylene Bluedrug

Intravenous infusion of methylene blue once daily for 3-5 consecutive days at doses of 1 mg/kg, 2 mg/kg, or 3 mg/kg, administered over 20 minutes, following CAR-T or bispecific antibody infusion in patients who develop Grade ≥1 CRS or ICANS.
