ATRN-119 in Combination With Decitabine in Patients With TP53-Mutated AML or Higher-Risk MDS
A Phase I Study of ATRN-119, an ATR Inhibitor, in Combination With Decitabine in Patients With TP53-Mutated AML or Higher-Risk MDS
This single-center, open-label, phase I study will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antileukemic activity of ATRN-119 (mosipasertib) alone and in combination with decitabine in patients with TP53-mutated AML or higher-risk myelodysplastic syndrome (HR-MDS). The primary objective is to identify the maximum tolerated dose (MTD) and recommended dose(s) for expansion (RDE) of ATRN-119 (mosipasertib) plus decitabine. The study is based on the hypothesis that ATR inhibition with ATRN-119 (mosipasertib) will enhance sensitivity to decitabine in TP53-mutated disease, resulting in deeper and more durable clinical responses.

-
Patients with R/R AML must have received at least 1 prior AML-directed treatment regimen appropriate for their disease and fitness. Patients with FLT3, IDH1, IDH2, or NPM1 mutations must also have previously received, or been deemed ineligible for, an approved targeted therapy directed against the relevant mutation. In addition, patients must meet at least one of the following criteria:
- Disease progression during treatment with, or failure to achieve CR, CRh, or CRi after ≥ 2 cycles of a hypomethylating agent (HMA) plus venetoclax.
- Disease progression during treatment with, or failure to achieve CR, CRh, or CRi after ≥ 4 cycles of HMA-based therapy when venetoclax was contraindicated, not tolerated, or otherwise considered clinically inappropriate.
- First relapse with an initial remission duration < 12 months
- First relapse following failed salvage chemotherapy
- Relapse after allogeneic hematopoietic cell transplant
- Second or subsequent relapse
-
Patients with R/R HR-MDS must have received at least 1 prior MDS-directed treatment regimen appropriate for their disease and fitness. Patients with IDH1 mutations must also have previously received, or been deemed ineligible for, an approved targeted therapy directed against the relevant mutation. Patients must meet at least one of the following criteria:
- Disease progression during treatment with, or failure to achieve CR, CRh, or CRi after ≥ 4 cycles of HMA-based therapy or 2 cycles of HMA in combination with another agent, including an investigational agent as part of a clinical trial or in routine clinical care.
