A Study of Different Programs to Help ALL Patients With Taking Maintenance Medicine at Home

PRIMARY OBJECTIVES:

I. Collect data on the feasibility of a phase 3 adherence-enhancing 2 parallel 2-arm randomized clinical trial.

Ia. Estimate participation rates, refusal reasons, and attrition rates. Ib. Evaluate rates of completeness of all aspects of the study (surveys [rates of missing elements]; MEMS® TrackCap™ return rates; maintenance form return rates from site clinical research assistants [CRAs]; blood samples for pharmacogenetics and deoxyribonucleic acid [DNA]-incorporated thioguanine nucleotide [DNA-TG] levels).

SECONDARY OBJECTIVES:

I. Among baseline non-adherers, estimate the impact of ultra-intensified intervention package (U-iIP) versus (vs.) intervention package (IP) on 6MP adherence.

II. Among baseline adherers, estimate the impact of patient-empowered intervention package (pIP) vs. education alone (EDU) on 6MP adherence.

OUTLINE:

Patients receive the Patient Supply Kit containing an empty MEMS® medication bottle with TrackCap™ with child resistant medication bottles and child resistant standard caps, and written instructions for the patient and pharmacist, along with their 6MP prescription. Beginning on day 1 cycle 1 of Maintenance Therapy, patients start using the MEMS® medication bottle with TrackCap™. Clinical research assistants contact patients and parents by telephone the next day to confirm that TrackCap™ is being used, to identify any obstacles, and to determine solutions. Patients are instructed to return the first MEMS® TrackCap™ to the clinic on day 1 of Maintenance cycle 2. Patients are then assigned to 1 of 2 groups based on baseline adherence rates (adherers [adherence rate >= 95%] and non-adherers [adherence rate \< 95%]).

NON-ADHERERS: Patients are randomized to 1 of 2 arms during cycle 2 of Maintenance therapy.

ARM I (IP): Patients receive another Patient Supply Kit and MEMS® TrackCap™ to use on day 1 of Maintenance cycle 3 and for the remaining duration of the study. Patients and their caregiver view the multimedia interactive patient/parent/other adult education (MIPE) program that features video clips of ALL patients and their parents/other adults discussing Maintenance treatment in the clinic on day 1 of cycle 3. A designated parent/other adult is selected and trained briefly in prompting and supervising the patient to take 6MP daily by the CRA on day 1 of Maintenance cycle 3. Patients also receive customized printed medication schedules approximately every 4 weeks (days 1, 29, and 57) during Maintenance cycles 3-5 (during scheduled clinic visits) from their healthcare provider. Patients and/or the parent/other adult receive automated customized electronic reminders delivered via smartphone according to the patient's electronic 6MP schedule. Once the designated parent/other adult receives the customized electronic reminder for 6MP, they are instructed to prompt initiation of the 6MP dose (if necessary), and to supervise the ingestion of the prescribed 6MP (in all instances). If the patient is not present when the dose of 6MP is due, the patient receives a call from the designated parent/other adult to prompt initiation of the dose. Patients and designated parents/other adults will be instructed to electronically indicate when 6MP has been taken (indicative of directly supervised therapy [DST] execution). Additionally, patients undergo blood sample collection on the study.

ARM II (U-iIP): Patients receive another Patient Supply Kit and MEMS® TrackCap™ to use on day 1 of Maintenance cycle 3 and for the remaining duration of the study. Patients and their caregiver view the MIPE program that features video clips of ALL patients and their parents/other adults discussing Maintenance treatment in the clinic on day 1 of cycle 3. A designated parent/other adult is selected and trained briefly in prompting and supervising the patient to take 6MP daily by the CRA on day 1 of Maintenance cycle 3. Patients also receive customized printed medication schedules approximately every 4 weeks (days 1, 29, and 57) during Maintenance cycles 3-5 (during scheduled clinic visits) from their healthcare provider. Patients and/or the parent/other adult receive automated customized electronic reminders delivered via smartphone according to the patient's electronic 6MP schedule. Once the designated parent/other adult receives the reminder for 6MP, they are instructed to prompt initiation of the 6MP dose (if necessary), and to supervise the ingestion of the prescribed 6MP (in all instances). If the patient is not present when the dose of 6MP is due, the patient receives a call from the designated parent/other adult to prompt initiation of the dose. Patients and designated parents/other adults will be instructed to electronically indicate when 6MP has been taken (indicative of DST execution). If there is no response by the designated parent/other adult indicating 6MP ingestion within 1 hour of the scheduled time, additional automated reminders are sent. The Adherence Study Coordinating Center will evaluate electronic responses (indicative of DST execution) every 4 weeks. The DST response rates will be communicated to the COG sites, identifying the patients as low DST responders (response rate: \< 85%) or high DST responders (response rate: ≥ 85%), along with instructions to serve as a guideline for communicating these results when reviewing them with their patient. DST response rates will be reviewed with the patient every 4 weeks at the clinic visit by the healthcare provider for all U-iIP patients (irrespective of response rate). Patients (and their designated caregiver) receive booster MIPE videos to view on their smartphone every 4 weeks (Days 1, 29, and 57) during Maintenance cycles 3-5, with content that reinforces the importance of 6MP in treating leukemia, having a daily routine for 6MP ingestion, and executing/confirming directly supervised therapy (DST) with each dose, and review common barriers to 6MP ingestion and DST execution (e.g., patient away from home, change in daily schedule), address additional barriers significantly associated with DST execution, and feature examples of patients/other adults self-identifying barriers (e.g., parent not always home at time of 6MP, lack of organizational skills, etc.), and provide specific steps to overcome the barriers. Additionally, patients undergo blood sample collection on the study.

ADHERERS: Patients are randomized to 1 of 2 arms during cycle 2 of Maintenance therapy.

ARM III (EDU: Patients receive another Patient Supply Kit and MEMS® TrackCap™ to use on day 1 of Maintenance cycle 3 and for the remaining duration of the study. Patients and their caregiver view the MIPE program that features video clips of ALL patients and their parents/other adults discussing Maintenance treatment in the clinic on day 1 of cycle 3. Additionally, patients undergo blood sample collection on the study.

ARM IV (pIP): Patients receive another Patient Supply Kit and MEMS® TrackCap™ to use on day 1 of Maintenance cycle 3 and for the remaining duration of the study. On day 1 of Maintenance cycle 3, patients and their caregiver view the MIPE program that features video clips of ALL patients and their parents/other adults discussing Maintenance treatment in the clinic. On day 1 of Maintenance cycle 3, the patient and a designated parent/other adult are trained to set daily reminders on their smartphones at the time the 6MP is due, and to use the "snooze" function to allow repeated reminders in case the medication cannot be taken when the alarm first goes off. The designated parent/other adult is also trained briefly by the CRA in prompting and supervising the patient to take 6MP daily. Once the designated parent/other adult hears the smartphone alarm for 6MP, they are instructed to prompt initiation of the 6MP dose (if necessary), and to supervise the ingestion of the prescribed 6MP (in all instances). If the patient is not present when the dose of 6MP is due, the patient receives a call from the designated parent/other adult to prompt initiation of the dose. Additionally, patients undergo blood sample collection on the study.
