Brief summary:
This was a Phase 2, open-label, multicenter study evaluating the preliminary efficacy and safety of venetoclax (ABT-199) administered orally in participants with acute myelogenous leukemia (AML).

Detailed description:
The primary objective was to evaluate the preliminary efficacy of venetoclax administered orally in participants with relapsed and/or refractory (R/R) acute myelogenous leukemia (AML) or frontline therapy in patients with AML who were unfit for intensive therapy. The secondary objective was to evaluate the preliminary safety of venetoclax administered orally in patients with AML. The first portion of the study was to consist of 19 participants with the objective of evaluating anti-tumor effects and confirming the safety of the regimen. The second portion (expansion) was to consist of 35 additional subjects to evaluate anti-tumor effects and safety and was to commence if an adequate efficacy signal (i.e., ≥ 5/19 achieved complete remission \[CR\], CR with incomplete bone marrow recovery \[CRi\] or partial remission \[PR\]) had been observed in the first portion of the study. The criterion for success would have been met if ≥ 16 of 54 participants achieved remission. The efficacy signal from first portion of the study was deemed insufficient for enrollment into the second portion of the study, as 4 of the 19 subjects achieved CR/CRi. During the trial, a number of participants were in screening at the point of the interim analysis. Given the early signs of clinical activity of venetoclax, disease severity, and prognosis of these participants without available options for therapy, they were allowed to initiate treatment ahead of completion of the interim analysis. Therefore, 32 participants were enrolled. No additional participants were screened or treated after the interim analysis was completed.

Arms:
arm 1: Continuous dosing of venetoclax (ABT-199) QD (once daily) beginning with dose-escalation on Week 1 Day 1. Participants received a dose of 20 mg of ABT-199 on Week 1 Day 1, 50 mg on Day 2, 100 mg on Day 3, 200 mg on Day 4, 400 mg on Day 5, 800 mg on Day 6 and QD thereafter.
