Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals diagnosed with relapsed or refractory AML or related myeloid malignancies who are ineligible for standard chemotherapy.

Probably not a fit

Patients with early-stage AML or those who can tolerate standard chemotherapy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the safety and pharmacokinetics of APG-2575, both as a single agent and in combination with HHT or AZA, in patients suffering from relapsed or refractory acute myeloid leukemia (AML) and related myeloid malignancies. It consists of three stages: an initial dose-escalation of APG-2575 alone, followed by a dose-escalation of APG-2575 combined with HHT or AZA, and finally an expansion cohort to determine the maximum tolerated dose and recommended phase 2 dose of the combination regimen. The study is open-label and multi-center, allowing for a diverse patient population.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat forms of AML.

How similar studies have gone: Other studies have shown promise with Bcl-2 inhibitors in treating AML, suggesting potential for success with this approach.
