Myeloid Malignancy | Drug: APR-246 Drug: Venetoclax Drug: Azacitidine | Phase 1 |
This study will enroll adult male and female patients of age ≥ 18 years with documented diagnosis of AML, according to WHO classification, and documented TP53 mutation which is not benign or likely benign, who also meet the eligibility requirements of this protocol.
The study will include a safety lead-in dose-finding portion followed by expansion portion. During the safety lead-in portion of the study, two cohorts will independently enroll patients following a 3 + 3 design. Each cohort will enroll up to 6 patients.
The expansion portion will begin once the recommended phase II dose (RP2D) of APR-246 in combination with venetoclax and in combination with venetoclax and azacitidine have been determined in order to assess the antitumor activity of these combinations.

- To evaluate the tolerabililty and the Incidence of Treatment-Emergent Adverse Events of administration of APR 246 in combination with venetoclax and azacitidine in patients with TP53 mutant myeloid malignancies. [ Time Frame: From baseline until event occures, i.e. through study completion, an average of 1 year ]1. Dose-limiting toxicities (DLTs), classified and graded according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE, version 5.0).
- To evaluate the tolerabililty and the Incidence of Treatment-Emergent Adverse Events of administration of APR 246 in combination with venetoclax and azacitidine in patients with TP53 mutant myeloid malignancies. [ Time Frame: From baseline until event occures, i.e. through study completion, an average of 1 year ]2. Frequency of treatment-emergent adverse events (TEAEs), and serious adverse events (SAEs) related to APR-246 in combination with venetoclax and azacitidine during the trial.
