Why are we doing this research?
An open-label, global, multi-center study to evaluate the safety and pharmacokinetics of venetoclax monotherapy, to determine the dose limiting toxicity (DLT) and the recommended Phase 2 dose (RPTD), and to assess the preliminary efficacy of venetoclax in pediatric and young adult participants with relapsed or refractory malignancies.
Study Type: Interventional
Intervention Model: Single Group Assignment
Primary Purpose: Treatment
