Understanding the Role of Adherence in the Ethnic Differences in Survival After Childhood ALL
OBJECTIVES:
Primary
- Determine and compare adherence to maintenance mercaptopurine using the following
assessments: serial red cell mercaptopurine metabolites (i.e., 6TGN and methylTIMP),
frequency of mercaptopurine dosing using an electronic pill monitoring system (MEMS^®),
and self-report of adherence to mercaptopurine by questionnaire in a cohort of younger
patients with acute lymphoblastic leukemia in first remission who belong to four
different ethnic and racial groups (Caucasians, African-Americans, Hispanics, and
Asians).
- Determine the impact of adherence to mercaptopurine on event-free-survival (EFS) in the
entire cohort, after adjusting for known predictors of disease outcome.
- Define a critical level of adherence that has a significant impact on EFS for the
entire cohort.
- Describe prevalence of adherence to mercaptopurine by ethnicity.
- Describe behavioral and sociodemographic predictors of adherence.
- Describe the pill-taking practices in this cohort.
- Evaluate the impact of adherence on ethnic/racial difference in EFS.
Secondary
- Assess the concordance among 6TGN and methylTIMP levels, electronic pill monitoring,
and self-reported adherence in the ethnic/racial groups.
OUTLINE: This is a multicenter study.
Patients* receive an electronic pill monitoring system comprising an empty MEMS^® medication
bottle with TrackCap™ child resistant (CR). The mercaptopurine prescription is filled using
this system. Beginning on day 1 of the third or later course of maintenance therapy,
patients take all doses of mercaptopurine from the MEMS^® medication bottle with TrackCap™
CR for at least 6 months. The MEMS^® TrackCap™ CR is mailed to the study center at the end
of study. Patients also receive oral methotrexate as indicated by their individual
chemotherapy regimen.
NOTE: *Study closed to accrual for Caucasian and Hispanic patients as of 8/14/2009.
Blood samples are collected on days 1, 29, 57, 85, 113, 141, and 169. Patient or caregiver
completes demographic questionnaire on day 29. Patient and/or caregiver completes a
self-reported adherence questionnaire on days 29, 57, 113, and 141.
After completion of study treatment, patients are followed periodically.
PROJECTED ACCRUAL: A total of 720 patients will be accrued for this study.
