What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 72 participants in total. It began in 2024-07-05 with a primary completion date of 2026-12-31.

Brief Summary

The purpose of this prospective, multi-center, single-arm, phase 2 study is to evaluate the efficacy and safety of a combination regimen of mitoxantrone hydrochloride liposome injection, standard-dose of cytarabine and venetoclax (MAV) in the treatment of relapsed or refractory (R/R) AML. The study plan to enroll 72 R/R AML patients who are expected to receive laboratory tests of bone marrow and blood specimens at regular times after MAV treatment.
