NCT ID NCT07692529

First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time

Summary

This early study tests an experimental drug called zeprumetostat in people with a rare type of leukemia (T-cell large granular lymphocyte leukemia) that has not responded to or has come back after other treatments. Ten participants take the drug twice daily for two 28-day cycles. The goal is to see if the drug can improve blood counts and reduce the need for transfusions, while also checking for side effects.
