What affects how daily 6-mercaptopurine works in teens and young adults with ALL

Predictors of Systemic Exposure to Oral 6MP During Maintenance in Adolescentsand Young Adults with Acute Lymphoblastic Leukemia

NIH-funded research University of Alabama at Birmingham · NIH-11285487

This work looks at why some adolescents and young adults with acute lymphoblastic leukemia have lower amounts of the active 6-mercaptopurine metabolite in their body during maintenance treatment.

What this research studies

If you are a teen or young adult on maintenance therapy for ALL taking daily 6-mercaptopurine (6MP), researchers will measure the active 6MP metabolite incorporated into DNA (DNA-TG) to see how much drug exposure you have. They will combine those lab measurements with information about how you take your medicine and the dose intensity your provider prescribes. The team will also collect information about barriers and supports that affect taking 6MP and how healthcare is managed during maintenance. Findings will be used to link real-world medication use and provider practices to lab-measured drug exposure in AYA patients.

Who could benefit from this research

Good fit: Teens and young adults (roughly ages 15–39) with acute lymphoblastic leukemia who are in the maintenance phase taking daily oral 6-mercaptopurine are ideal candidates.

Not a fit: People who are not on daily 6MP maintenance (for example those in induction/consolidation or receiving different therapies) or who have other cancers are unlikely to benefit directly from this work.

Why it matters

Potential benefit: If successful, this could help identify patients with low 6MP exposure and guide targeted support or dosing changes to lower relapse risk.

How similar studies have performed: Previous large studies have shown that low DNA-TG levels link to higher relapse risk, but focused work on AYA-specific adherence and provider dose practices is newer.
