Clinical Trial Summary

This is a Phase 1 dose-escalation study of PRT1419, a myeloid cell leukemia-1 (MCL-1) inhibitor, in participants with selected relapsed/refractory myeloid or B-cell malignancies. The purpose of this study is to evaluate the safety and tolerability of PRT1419 monotherapy and in combination with either azacitidine or venetoclax, describe any dose limiting toxicities (DLTs), define the dosing schedule, and to determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D).


Clinical Trial Description

This is a multicenter, open-label, dose-escalation, Phase 1 study of PRT1419, a MCL-1 inhibitor, evaluating participants with acute myeloid leukemia (AML), chronic myelomonocytic leukemia (CMML), myelodysplastic syndrome (MDS), MDS/myeloproliferative neoplasm (MPN) overlap syndrome, chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), and B-cell non-hodgkin lymphoma (NHL) including marginal zone lymphoma, follicular lymphoma or mantle cell lymphoma. Participants in study will receive PRT1419 as monotherapy or in combination with either Azacitidine (AZA) or Venetoclax (VEN). The study includes multiple dose escalations and expansion cohorts for RP2D confirmation. ;
