Brief Summary:
This study is being done to determine if treatment with azacitidine and venetoclax is effective treatment for elderly patients with acute myeloid leukemia (AML) who have not received previous treatment. Azacitidine and venetoclax will be given as induction treatment followed by venetoclax maintenance treatment for patients who respond to the induction treatment.

Condition or disease Intervention/treatment Phase
Acute Myeloid Leukemia Drug: Azacitidine and Venetoclax Phase 2

Detailed Description:
This is a phase 2 study for elderly patients who have not received previous treatment for acute myeloid leukemia (AML). Up to 42 patients will be enrolled. All patients will be treated with azacitidine and venetoclax until a minimal residual disease (MRD) negative response is achieved. Once patients achieve a MRD negative composite response, azacitidine will be discontinued and venetoclax dose will be decreased to "maintenance" dose.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 42 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Azacitidine and Venetoclax (ABT-199) as Induction Therapy With Venetoclax Maintenance in Previously Untreated Elderly Patients With Acute Myeloid Leukemia (AML)
Actual Study Start Date : May 15, 2018
Estimated Primary Completion Date : June 28, 2023
Estimated Study Completion Date : October 2024

Arm Intervention/treatment
Experimental: Azacitidine and Venetoclax
On day 1 of cycle 1, Azacitidine 75 mg/m2 will be given by injection or infusion, and will continue for 7 days. Azacitidine doses will be given in subsequent cycles for patients who do not achieve response. Venetoclax will be administered orally once daily on days 2 through 28 in cycle 1. Beginning with cycle 2, and each subsequent cycle, venetoclax will be administered Days 1 through 28.
Drug: Azacitidine and Venetoclax
Azacitidine will be given at dose of 75mg/m2 in Cycle 1 days 1-7; repeat in cycle 2 and 3 if no response. Starting on day 2 of cycle 1, venetoclax will be administered orally with doses increased to a target dose of 600 mg (administer 100 mg on day 2, 200 mg on day 3, 400 mg on day 4 and 600 mg on day 5), then 600 mg daily.

Primary Outcome Measures :
  1. Duration of response to azacitidine and venetoclax treatment [ Time Frame: From the first day a response is documented to the first day of disease progression ]
    Determine how long responses last in patients treated with azacitidine and venetoclax followed by venetoclax maintenance treatment

Secondary Outcome Measures :
  1. Frequency of Minimal Residual Disease (MRD) negative composite responses within the "induction phase" of azacitidine and venetoclax [ Time Frame: From Day 28, the first day a response is documented to end of cycle bone marrow biopsies, through 5 years ]
    The number of patients who achieve an MRD negative composite response

  2. The time needed to achieve an MRD negative composite response [ Time Frame: From first dose of treatment to first day response is documented by bone marrow biopsy ]
    The median number of days that have elapsed leading to an MRD negative composite response

  3. The one-year overall survival (OS) of older, newly diagnosed AML patients treated with "induction phase" of azacitidine with venetoclax followed by a maintenance Phase of venetoclax alone. [ Time Frame: From date of study enrollment to one year after enrollment ]
    The number of patients who survive to one year after date of study enrollment

  4. Hematologic Toxicity as defined by the 2017 ELN AML Recommendations [ Time Frame: From the day venetoclax with azacitidine is administered to the end of maintenance venetoclax alone, up to one year ]
    Hematologic toxicities will be measured by incidence of febrile neutropenia, ≥ grade 2 bleeding complications and number of transfusions received
