Summary

This early-phase study tests whether a customized immune cell therapy (anti-CD22 CAR T cells) is safe for people with hairy cell leukemia (classic or variant) that has returned or not responded to standard treatments. Up to 27 adults will receive the therapy after mild chemotherapy. The goal is to check for side effects and see if the treatment can shrink the cancer.
