Venetoclax and Azacitidine for the Treatment of Acute Myeloid Leukemia in the Post-Transplant Setting

Brief Title

Venetoclax and Azacitidine for the Treatment of Acute Myeloid Leukemia in the Post-Transplant Setting

Official Title

A Phase II Study of Venetoclax in Combination With Azacitidine in the Post-Transplant Setting for AML, T Cell ALL, and Mixed Phenotype Acute Leukemia

Brief Summary

      This phase II trial studies how well venetoclax and azacitidine work for the treatment of
      acute myeloid leukemia after stem cell transplantation. Venetoclax, a BCL-2 inhibitor, and
      azacitidine may stop the growth of cancer cells by blocking some of the enzymes needed for
      cell growth. Giving venetoclax and azacitidine after a stem cell transplant may help control
      high risk leukemia and prevent it from coming back after the transplant.
    

Detailed Description

      PRIMARY OBJECTIVE:

      I. To determine relapse-free survival after the use of venetoclax in combination with
      azacitidine given as maintenance therapy or for eradication of minimal residual disease in
      patients with high risk acute myeloid leukemia (AML) after hematopoietic stem cell
      transplantation (HSCT).

      SECONDARY OBJECTIVES:

      I. To determine the safety and toxicity of venetoclax in combination with azacitidine (type,
      frequency, severity of adverse events [AEs] and relationship of adverse events [AEs] to
      venetoclax).

      II. To determine response duration, overall survival. III. To determine incidence of acute
      and chronic graft versus host disease (GVHD).

      IV. To perform matched pairs analysis to obtain bias corrected treatment comparisons of
      venetoclax + azacitidine (vidaza) (V+V) to standard therapy in the acute myeloid leukemia
      (AML) patients with no evidence of disease (AML D-) subgroup.

      EXPLORATORY OBJECTIVE:

      I. To investigate possible relationships between baseline protein and gene expression
      signatures/mutation profile and BH3 profiling in predicting relapse-free survival time to the
      combination.

      OUTLINE:

      Patients receiving venetoclax and azacitidine for maintenance after allogeneic stem cell
      transplantation, receive azacitidine subcutaneously (SC) on days 1-5 and venetoclax orally
      (PO) once daily (QD) on days 1-7. Patients receiving venetoclax and azacitidine for minimal
      residual disease after allogeneic stem cell transplant, receive azacitidine SC on days 1-7
      and venetoclax PO QD on days 1-14. Treatment repeats every 4-8 weeks for up to 12 cycles in
      the absence of disease progression or unacceptable toxicity.
