Brief Summary:
This study aims to treat non-elderly adult patients, who were previously untreated for acute myeloid leukemia, using venetoclax and azacitidine.

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

Detailed Description:
This is a phase II study that seeks to treat patients ages 18-59 who have acute myeloid leukemia but have never been treated before. It will use venetoclax and azacitidine, and patients can receive up to four cycles of this medication. Depending on the level of recovery, patients will either be forced to come off study or have the option to continue the medication, receive maintenance therapy, or pursue an allogeneic stem cell transplant.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 30 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Safety and Efficacy of Venetoclax and Azacitidine for Newly Diagnosed Non-Elderly Adult Patients (Aged 18-59) With Acute Myeloid Leukemia
Actual Study Start Date : November 14, 2018
Estimated Primary Completion Date : June 2022
Estimated Study Completion Date : June 2023


Arm Intervention/treatment
Experimental: Azacitidine and Venetoclax
Azacitidine will be given intravenously for 7 days. Venetoclax will be given orally. The patient will start out with 100mg and progress to 600mg. Once 600mg is reached, the patient will stay at this dose until the 28 day cycle is finished.
Drug: Azacitidine
On day 1 of cycle 1, azacitidine 75 mg/m2 SC or IV will be given, and will continue for 7 days.

Drug: Venetoclax
Starting on day 2 of cycle 1, venetoclax will be initiated. It will be dose escalated to a target dose of 600 mg in the following manner: 100 mg on day 2, 200 mg on day 3, 400 mg on day 4 and 600 mg on day 5. The patient then continues to take the 600mg dose for the remainder of the 28 day cycle. Each dose of venetoclax will be self-administered with approximately 240 mL of water within 30 minutes after the completion of a meal, preferably breakfast. The dose should be administered at the same time each day. On days the subject is given azacitidine, venetoclax must be given first.




Primary Outcome Measures :
  1. Response Rate, measured by the European Leukemia Net definition: (CRMRD-+CR+CRi+MLFS) [ Time Frame: Study start date to study end date, or death, whichever comes first, up to 4 years ]
    The (CRMRD-+CR+CRi+MLFS) shows non-inferiority of venetoclax with azacitidine when compared with historical controls who received induction chemotherapy.


Secondary Outcome Measures :
  1. Incidence of Minimal Residual Disease (MRD) Negative Responses [ Time Frame: Study start date to study end date, or death, whichever comes first, up to 4 years ]
    Number of new cases of Complete Remission, Complete Remission with Incomplete Blood Count Recovery, or Morphologic Leukemia Free State. This will be measure by multi-dimensional flow cytometry with a sensitivity to 0.1%.

  2. Remission Duration [ Time Frame: Study start date to study end date, or death, whichever comes first, up to 4 years ]
    Remission Duration will be defined as the length of time a patient does not display leukemic blasts or extramedullary disease

  3. One Year Event Free Survival [ Time Frame: Study start date to study end date, or death, whichever comes first, up to 4 years ]
    Determined using Kaplan Meier survival analysis methods with 95% confidence intervals.

  4. Overall Survival [ Time Frame: Study start date to study end date, or death, whichever comes first, up to 4 years ]
    Overall Survival will be defined as the time from administration of the initial doses until death from any cause. Determined using Kaplan Meier survival analysis methods with 95% confidence intervals.

  5. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [ Time Frame: Study start date to study end date, or death, whichever comes first, up to 4 years ]
    Safety and tolerability analysis of azacitidine and venetoclax will be summarized by dose and severity as assessed by the Common Toxicity Criteria for Adverse Events (CTCAE) version 4.0 and relationship to study drug.
