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 in treating participants with acute myeloid leukemia that has come back (recurrent) or that does not respond to treatment (refractory). Milademetan tosylate 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. Giving milademetan tosylate and low-dose cytarabine may work better in treating participants with recurrent or refractory acute myeloid leukemia.

Condition or disease Intervention/treatment Phase
Recurrent Acute Myeloid Leukemia Refractory Acute Myeloid Leukemia TP53 wt Allele Drug: Cytarabine Drug: Milademetan Tosylate Phase 1 Phase 2

Detailed Description:

PRIMARY OBJECTIVES:

I. 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) in relapsed/refractory (non-TP53 mutant) patient population.

SECONDARY OBJECTIVES:

I. Evaluation of time to response variables including overall survival (OS), event-free survival (EFS) and duration of response (DOR).

II. Determine biomarkers that may be predictive of DS-3032b (milademetan tosylate) activity.

III. Molecular profiling at screening, on study, and at relapse to determine genomic predictors of response and resistance.

OUTLINE: This is a dose escalation study of milademetan tosylate, followed by a phase II study.

Participants receive low dose cytarabine subcutaneously (SC) twice daily (BID) on days 1-7 and receive milademetan tosylate orally (PO) once daily (QD) on days 8-21. 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.

Primary Outcome Measures :
  1. Incidence of adverse events (Phase I) [ Time Frame: Up to 1 year ]
    Graded according to Common Terminology Criteria for Adverse Events version 5.0.

  2. Maximum tolerated dose (MTD) (Phase I) [ Time Frame: 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.

  3. Overall response rate (Phase II) [ Time Frame: Up to 28 days ]
