A Phase 1b/2 Study of TP-0903 and Decitabine Targeting Mutant TP53 and/or Complex Karyotype in Patients with Untreated Acute Myeloid Leukemia ≥Age 60 Years.

ABSTRACT:

Purpose

Older patients who have acute myeloid leukemia (AML) with mutant TP53 and/or complex karyotype have a dismal prognosis and lack treatment options. Having previously demonstrated that TP-0903, a multikinase inhibitor, has compelling preclinical activity in drug-resistant AML, including TP53-mutated AML, we evaluated the clinical activity of TP-0903 in combination with decitabine.

Patients and methods

This was a multicenter, open-label, phase 1b/2 substudy of Beat AML Master Trial (ClinicalTrials.gov: NCT03013998). The phase 1b portion used a 3 + 3 design, and the phase 2 portion used a Simon two-stage design. Eligible patients ages ≥60 years who had newly diagnosed AML with mutations in TP53 and/or complex karyotype (≥3 cytogenetic abnormalities) received either 37 mg
