Brief Summary:
This phase II trial investigates how well azacitidine, venetoclax, and trametinib work in treating patients with acute myeloid leukemia or higher-risk myelodysplastic syndrome that has come back (relapsed) or has not responded to treatment (refractory). Chemotherapy drugs, such as azacitidine, 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. Venetoclax and trametinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. The goal of this study is learn if the combination of azacitidine, venetoclax, and trametinib can help to control acute myeloid leukemia or myelodysplastic syndrome.

Condition or disease Intervention/treatment Phase
Recurrent Acute Myeloid Leukemia Recurrent Chronic Myelomonocytic Leukemia Recurrent Myelodysplastic Syndrome Refractory Acute Myeloid Leukemia Refractory Chronic Myelomonocytic Leukemia Refractory Myelodysplastic Syndrome Drug: Azacitidine Drug: Trametinib Drug: Venetoclax Phase 2

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine overall survival rate at 1 year of the regimen in patients with newly diagnosed acute myeloid leukemia (AML). (Cohort A) II. To determine the complete remission (CR)/complete remission without recovery of counts (CRi) rate of the regimen in patients with relapsed/refractory AML or high-risk myelodysplastic syndrome (MDS). (Cohort B)

SECONDARY OBJECTIVES:

I. To assess other efficacy endpoints (CR rate, minimal residual disease negativity by flow cytometry, relapse-free survival, event-free survival, and overall survival).

II. To assess proportion of patients proceeding to hematopoietic stem cell transplantation (HSCT).

III. To determine the safety of the combination regimen.

EXPLORATORY OBJECTIVES:

I. To evaluate the impact of baseline genomic alterations on response and survival of the combination regimen.

II. To evaluate clonal evolution from diagnosis to relapse.

OUTLINE:

INDUCTION (CYCLE 1): Patients receive azacitidine intravenously (IV) over 30-60 minutes or subcutaneously (SC) on days 1-7, venetoclax orally (PO) once daily (QD) on days 1-28, and trametinib PO QD on days 1-28 in the absence of disease progression or unacceptable toxicity.

CONSOLIDATION (CYCLES 2-24): Patients receive azacitidine IV over 30-60 minutes or SC on days 1-7, venetoclax PO QD on days 1-21, and trametinib PO QD on days 1-28. Treatment repeats every 28 days for up to 23 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, and then every 6 months thereafter.

Outcome Measures
Go to

Primary Outcome Measures :
  1. Overall survival (Cohort A) [ Time Frame: From the first day of treatment to time of death from any cause, assessed at 1 year ]
    Will be calculated. The distribution will be estimated using the method of Kaplan and Meier. Comparisons by important subgroups (e.g., baseline genomic alterations) will be made using the log-rank tests.

  2. Complete remission(CR)/complete remission without recovery of counts (CRi) (Cohort B) [ Time Frame: Up to 6 cycles of treatment (each cycle = 28 days) ]
    Will estimate the CR/CRi for the combination treatment (defined as the proportion of patients achieving CR or CRi within 6 cycles of treatment), along with the 95% credible interval.


Secondary Outcome Measures :
  1. Complete response rate [ Time Frame: Up to 3 years ]
    Will be estimated along with 95% credible intervals.

  2. Minimal residual disease negativity [ Time Frame: Up to time of relapse, assessed up to 3 years ]
    Will be assessed by flow cytometry and estimated along with 95% credible intervals.

  3. Relapse-free survival [ Time Frame: From documented CR/CRi until relapse or death, assessed up to 3 years ]
    Will be calculated. The distribution will be estimated using the method of Kaplan and Meier. Comparisons by important subgroups (e.g., baseline genomic alterations) will be made using the log-rank tests.

  4. Event-free survival [ Time Frame: From the first day of treatment until any treatment failure (lack of response within 6 cycles of treatment, relapse, or death), assessed up to 3 years ]
    Will be calculated. The distribution will be estimated using the method of Kaplan and Meier. Comparisons by important subgroups (e.g., baseline genomic alterations) will be made using the log-rank tests.

  5. Overall survival [ Time Frame: From the first day of treatment to time of death from any cause, assessed up to 3 years ]
    Will be calculated. The distribution will be estimated using the method of Kaplan and Meier. Comparisons by important subgroups (e.g., baseline genomic alterations) will be made using the log-rank tests.

  6. Proportion of patients proceeding to hematopoietic stem cell transplantation [ Time Frame: Up to 3 years ]
    Will be estimated along with 95% credible intervals.
