Omacetaxine and Venetoclax for the Treatment of Relapsed or Refractory Acute Myeloid Leukemia or Myelodysplastic Syndrome Harboring Mutant RUNX1

Hematopoietic and Lymphoid Cell Neoplasm Clinical Trial

Official title: Phase Ib/II Study of Omacetaxine and Venetoclax for Patients With Relapsed/Refractory Acute Myeloid Leukemia or Myelodysplastic Syndrome Harboring Mutant RUNX1

Status Active, not recruiting

Clinical Trial Summary

This phase Ib/II trial best dose, possible benefits and/or side effects of omacetaxine and venetoclax in treating patients with acute myeloid leukemia or myelodysplastic syndrome that has come back (recurrent) or does not respond to treatment (refractory) and have a genetic change RUNX1. Drugs used in chemotherapy, such as omacetaxine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Venetoclax may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving omacetaxine and venetoclax may help to control the disease.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To determine the safety and tolerability and recommended phase 2 dose (RP2D) of omacetaxine in combination with venetoclax for patients with relapsed/refractory acute myeloid leukemia or myelodysplastic syndrome harboring a RUNX1 mutation. (Phase 1b) II. To determine the efficacy of omacetaxine in combination with venetoclax for patients with relapsed/refractory acute myeloid leukemia or myelodysplastic syndrome harboring a RUNX1 mutation. (Phase II)

SECONDARY OBJECTIVES:

I. To determine duration of response (DOR), event-free survival (EFS), and overall survival (OS).

II. To evaluate occurrence of minimal residual disease (MRD) negative status by multiparameter flow cytometry and molecular evaluation.

EXPLORATORY OBJECTIVE:

I. To investigate global gene expression profiles, deoxyribonucleic acid (DNA) methylation profiles, BH3 profiling and other potential prognostic markers to explore predictors of antitumor activity and/or resistance to treatment.

OUTLINE: This is a phase I, dose de-escalation study followed by a phase II study.

Patients receive omacetaxine subcutaneously (SC) twice daily (BID) on days 2-3 or 2-4, and venetoclax orally (PO) on days 1-7, 1-10 or 1-14. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up within 30 days, then every 3 months for 3 years. ;
