PRIMARY OBJECTIVES:~I. To determine the maximum tolerated dose (MTD), recommended phase 2 dose (RP2D), and safety of revumenib (SNDX-5613) combined with 7 + 3 induction in newly diagnosed, untreated, NPM1-mutated/FLT3-ITD wild type and NPM1-mutated/FLT3-TKD wild type or MLL(KMT2A)-rearranged, acute myeloid leukemia (AML) patients >= 18-75 years old who are candidates for intensive induction therapy.~II. To determine the maximum tolerated dose (MTD), recommended phase 2 dose (RP2D), and safety of SNDX-5613 combined with one cycle of consolidation with high dose cytarabine in newly diagnosed AML patients in complete response/complete response with incomplete count recovery (CR/Cri) after intensive induction therapy with 7+3 for NPM1-mutated/FLT3-ITD wild type and NPM1-mutated/FLT3-TKD wild type or MLL (KMT2A)-rearranged AML patients >= 18-75 years old who are candidates for intensive therapy.~SECONDARY OBJECTIVE:~I. Evaluate the pharmacokinetics of SNDX-5613 with this combination regimen and characterize clinically relevant drug-drug interactions with antifungal agents.~EXPLORATORY OBJECTIVES:~I. Explore potential biomarker indicators of response and resistance in AML samples.~II. To determine the number of patients with CR/Cri out of the total number of patients treated at each dose level of this regimen.~III. To determine the measurable residual disease negative (MRD) response (CR/Cri) and its relation to CR/Cri status out of the total number of patients treated at each dose level of this regimen.~IV. Determine number of patients that undergo hematopoietic stem cell transplant (HSCT) out of the total number of patients treated at each dose level of this regimen.~V. Assess changes in OATP1B and CYP3A plasma biomarkers during treatment with SNDX-5613 with or without antifungal agents.~VI. Determine duration of response.~OUTLINE: This is a phase Ib, dose-escalation study of revumenib followed by a dose-expansion study.~INDUCTION: Patients receive revumenib orally (PO) every 12 hours (Q12h) on days 2-28, daunorubicin intravenously (IV) over 15 to 30 minutes on days 1-3, and cytarabine by continuous IV infusion (CIV) on days 1-7 in the absence of disease progression or unacceptable toxicity. Patients who achieve a response to Induction treatment continue to Consolidation treatment. Patients with persistent disease continue to Re-Induction treatment. Patients also undergo a transthoracic echocardiogram (ECHO) or multigated acquisition scan (MUGA) during screening, bone marrow aspiration and biopsy during screening and at the end of Induction, and collection of blood during screening, on days 2, 3, 15, and at the end of Induction.~RE-INDUCTION: Patients receive revumenib PO Q12h on days 2-28, daunorubicin IV over 15 to 30 minutes on days 1-2, and cytarabine CIV on days 1-5 in the absence of disease progression or unacceptable toxicity. Patients who achieve a response to Re-Induction treatment continue to Consolidation. Patients also undergo a transthoracic ECHO or MUGA on day 1 and bone marrow aspiration and biopsy at the end of Re-Induction.~CONSOLIDATION: Patients receive revumenib PO Q12h on days 2-28 and cytarabine CIV on days 1-3 in the absence of disease progression or unacceptable toxicity. Patients also undergo bone marrow aspiration and biopsy at the end of Consolidation, and collection of blood on days 2, 3, 15, and at the end of Consolidation.~After completion of study treatment, patients are followed for 30 days or until death, whichever occurs first.
This phase Ib trial tests the safety, side effects, and best dose of SNDX-5613 when given in combination with the standard chemotherapy treatment (daunorubicin and cytarabine) in treating patients with newly diagnosed acute myeloid leukemia that has changes in the NPM1 gene or MLL/KMT2A gene. SNDX-5613 blocks signals passed from one molecule to another inside cancer cells that are needed for cancer cell survival. Drugs used in chemotherapy, such as daunorubicin and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Adding SNDX-5613 to the standard chemotherapy treatment may be able to shrink or stabilize the cancer for longer than the standard chemotherapy treatment alone.
