Summary
Brief summary
The purpose of this study is to determine whether Venetoclax (a new drug), when combined with chemotherapy, improves response to treatment.

Who is it for?

You may be eligible to participate in this trial if you are aged 18 years or over, have been diagnosed with relapsed acute myeloid leukemia

Study Details
Eligible participants will receive venetoclax in combination with low-dose cytarabine. Treatment (each cycle is 28 days) will be given until disease progression, unacceptable toxicity, or withdrawal of consent.
Participants will be required to have blood samples taken at the beginning of each cycle along with a medical exam in order for researchers to monitor whether the treatment is safe and whether it is effectively treating the leukemia.
It is hoped that the findings of this trial will establish the benefits of venetoclax in combination with cytarabine for the treatment of leukemia patients early in the course of their disease.
