Brief Summary
A study to evaluate if the randomized addition of venetoclax to a chemotherapy backbone (fludarabine/cytarabine/gemtuzumab ozogamicin \[GO\]) improves survival of children/adolescents/young adults with acute myeloid leukemia (AML) in 1st relapse who are unable to receive additional anthracyclines, or in 2nd relapse.
Brief Title
Venetoclax in Children With Relapsed Acute Myeloid Leukemia (AML)
Detailed Description
Relapse of AML is driven by chemotherapy resistant stem cells. One mechanism of chemotherapeutic resistance in AML is the overexpression of the protein B-cell lymphoma 2 (BCL-2), an anti-apoptotic protein which sequesters intracellular activators of apoptosis. Venetoclax is a selective, potent, orally bioavailable, small molecule inhibitor of BCL-2 that restores programmed cell death in cancer cells.
This is a trial for children, adolescents and young adults with 2nd relapsed AML or 1st relapsed AML unable to receive additional anthracycline.
This is randomized trial of venetoclax in combination with intensive chemotherapy (fludarabine/cytarabine/gemtuzumab ozogamicin) for the first two cycles (42-day-cycles) that would inform and evaluate if this agent is an effective option for this population to improve its poor prognosis. Participants can receive up to two cycles of induction chemotherapy before hematopoietic stem cell transplantation (HSCT). If participants who have perceived clinical benefit cannot be transplanted after the 2 cycles, maintenance treatment may be given at the discretion of the investigator. In Arm B (experimental arm), participants can continue venetoclax if they have perceived clinical benefit, and maintenance therapy will combine venetoclax with azacitidine for a maximum of 24 cycles. In Arm A (control arm), participants will receive azacitidine in monotherapy. Maintenance is continued until clinical progression or unacceptable toxicity with a maximum of 24 cycles.

* Participants must have one of the following:
1. Children, adolescents, and young adults with AML without demonstrated FLT3/internal tandem duplication (ITD) mutation. Ideally, the status of the mutation needs to be proven in the current relapse. Nevertheless, patients with previous FLT3/ITD negative test from prior lines can be included based on local results in order to not delay the start of treatment.
2. And participants must have AML which is either:
* Untreated second relapse, in participants who are sufficiently fit to undergo another round of intensive chemotherapy, or
* Untreated first relapse, in participants who cannot tolerate additional anthracycline containing chemotherapy per investigator discretion.
