A Study Assessing Compliance with Mercaptopurine Treatment in Children with Acute Lymphoblastic Leukemia in First Remission


About this study

This randomized phase III trial studies compliance to a mercaptopurine treatment intervention compared to standard of care in younger patients with acute lymphoblastic leukemia in remission. Assessing ways to help patients who have acute lymphoblastic leukemia to take their medications as prescribed may help them in taking their medications more consistently and may improve treatment outcomes.
