Leukemia drug trial pulled before it even started

NCT ID NCT06522373

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This was a very early (Phase 1) study to test the safety of a new drug called MT-0169 in people with certain types of acute leukemia (AML or T-ALL) that had come back or not responded to treatment. The drug was given through a vein. However, the study was withdrawn before any patients were enrolled, so no results are available.
