Milademetan Tosylate and Low-Dose Cytarabine With or Without Venetoclax in Treating Participants With Recurrent or Refractory Acute Myeloid Leukemia
Study Details
Study Description
Brief Summary
This phase I/II trial studies the side effects and best dose of milademetan tosylate and to see how well it works with cytarabine with or without ventoclax in treating participants with acute myeloid leukemia that has come back (recurrent) or that does not respond to treatment (refractory). Milademetan tosylate and ventoclax may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as 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. It is not yet known if giving milademetan tosylate and low-dose cytarabine with or without ventoclax will work better in treating participants with recurrent or refractory acute myeloid leukemia.

Phase 1/Phase 2 |
Detailed Description
PRIMARY OBJECTIVES:
- To evaluate the safety and tolerability. (Phase 1) II. To determine the recommended phase II dose. (Phase I) III. To evaluate the efficacy (by International Working Group [IWG] criteria - Phase 2) of the MDM2 inhibitor, milademetan tosylate (DS-3032b), in combination with low dose cytarabine (LDAC), with or without the addition of venetoclax in both the frontline and in relapsed/refractory (non-TP53 mutant) patient population.
SECONDARY OBJECTIVES:
-
Evaluation of time to response variables including overall survival (OS), event-free survival (EFS) and duration of response (DOR).
-
Determine biomarkers that may be predictive of DS-3032b activity. III. Molecular profiling at screening, on study, and at relapse to determine genomic predictors of response and resistance.
OUTLINE: This is a phase I, dose escalation study of milademetan tosylate, followed by a phase II study. Patients are assigned to 1 of 2 arms.
ARM A: Patients receive low dose cytarabine subcutaneously (SC) twice daily (BID) on days 1-10 and milademetan tosylate orally (PO) once daily (QD) on days 8-14, 8-21, or 5-7 and 15-17. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive low dose cytarabine SC BID on days 1-10, milademetan tosylate PO QD on days 8-14, 8-21, or 5-7 and 15-17, and venetoclax PO QD on days 1-14. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment participants are followed up at 30 days.

Outcome Measures
Primary Outcome Measures
- Incidence of adverse events (Phase I) [Up to 1 year]
Graded according to Common Terminology Criteria for Adverse Events version 5.0.
- Maximum tolerated dose (MTD) (Phase I) [Up to 28 days]
As determined by dose limiting toxicity (DLT). MTD is defined the highest dose at which no more than one patient out of 6 patients experience DLTs in the first cycle. A 3+3 algorithm will be applied for dose escalation or dose de-escalation.
- Overall response rate (Phase II) [Up to cycle 2 (each cycle is 28 days)]
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Diagnosis of acute myeloid leukemia (AML) by World Health Organization (WHO) 2016 criteria. Patients will be divided into 2 arms during the phase 2 portion:
-
Arm A: Subjects must have newly diagnosed AML
-
Arm B: Subjects must have refractory or relapsed AML
-
TP53 wild-type status on molecular testing performed within the last 3 months
-
Eastern Cooperative Oncology Group (ECOG) performance status =< 3
-
Creatinine clearance >= 60 mL/min, as calculated using the modified Cockcroft-Gault equation OR creatinine =< 1.5 x upper limit of normal (ULN)
-
Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 3 x ULN
-
Bilirubin =< 1.5 x ULN, unless resulting from hemolysis, Gilbert's disease or considered to be due to leukemic involvement
-
No gastrointestinal issues to interfere with oral medication absorption
-
No active uncontrolled infection or comorbidity that would interfere with therapy or place patient at increased risk
-
Subject (male and female) of childbearing/reproductive potential must agree to use double-barrier contraceptive measures or avoid intercourse during the study and for 90 days after the last dose of study drug
