Can a blue dye tame Immunotherapy's dangerous side effects?

NCT ID NCT07169487

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This early-phase trial tests whether methylene blue, a dye used in medicine for other conditions, can safely treat two serious side effects of certain cancer immunotherapies: cytokine release syndrome (CRS) and immune-related neurotoxicity (ICANS). The study will enroll 18 adults with blood cancers who develop these side effects after CAR-T or bispecific antibody treatment. Participants receive methylene blue infusions for 3-5 days at different doses to find the safest and most promising dose.

Active substance

methylene blue

What this could lead to

If it works, this could offer a new way to manage serious side effects of cancer immunotherapy, potentially making treatment safer and more tolerable.

What could go wrong

This is a very early Phase 1 trial with only 18 people, so it is too soon to know if methylene blue is safe or effective. The results may not apply to all patients.
