Study of Venetoclax in Combination With Decitabine in Subjects With Acute Myeloid Leukemia

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

University of Chicago

Brief Summary:
The main purpose of this study is to learn about the safety and tolerability of an experimental drug, Venetoclax, when it is given along with Decitabine in subjects diagnosed with acute myeloid leukemia (AML).

Condition or disease Intervention/treatment Phase
Acute Myeloid Leukemia Drug: Decitabine Drug: Venetoclax Phase 1

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 26 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase 1 Study of Venetoclax in Combination With Decitabine 10-Day Regimen in Subjects With Acute Myeloid Leukemia
Actual Study Start Date : November 18, 2019
Estimated Primary Completion Date : June 10, 2024
Estimated Study Completion Date : June 10, 2025

Arm Intervention/treatment
Experimental: Treatment

Cycle 1 of Treatment will be Decitabine days 1-10 plus Venetoclax ramp up on days 1-3 followed by Venetoclax target dose on days 4-21

Cycle 2 of Treatment will be Decitabine days 1-10 plus Venetcolax target dose days 1-21

During maintenance Decitabine on days 1-5 plus Venetoclax days 1-21

Drug: Decitabine

Decitabine will be administered intravenously at a dose of 20mg per day for 10 days during Cycle 1 (28 day cycle)

Decitabine will be administered intravenously at a dose of 20mg per day for 10 days of Cycle 2 (28 day cycle).

Decitabine will be administered intravenously at a dose of 20mg per day for 5 days of each 28 day maintenance cycle

Drug: Venetoclax
Venetoclax administered orally on days 1-21 of cycle 1, cycle 2 and maintenance (28 day cycles). Dose levels will be assigned at time of enrollment anywhere from 100mg-400mg. Dose escalation will follow the 3+3 study design.

Primary Outcome Measures :
  1. The rate of dose limiting toxicity (DLT) [ Time Frame: 24 months ]
    Determine the rate of subjects who experience a dose limiting toxicity and the maximum tolerable dose

Secondary Outcome Measures :
  1. Levels of toxicity with combination regimen [ Time Frame: 24 months ]
    Levels of toxicity experienced with the combination regimen will be reported using data summaries of adverse events, dose limiting toxicity and other safety parameters.

  2. Assessment of Overall Survival [ Time Frame: 24 months ]
    Survival will be measured in months from the date of subject enrollment to the date of death.
