ReSeT in ALL 2: A Randomized, Controlled Pilot Trial Testing an Optimized, Multi-component Mobile Health Intervention to Reduce Sedentary Time in Early Adolescents and Young Adults (eAYAs) With ALL During Maintenance Therapy

2026年7月29日 更新者：David Freyer, DO, MS、Children's Hospital Los Angeles

The goal of this clinical trial is to learn whether an optimized, multi-component mobile health intervention (ReSeT2) can reduce sedentary behavior in adolescents and young adults with acute lymphoblastic leukemia (ALL) who are receiving maintenance therapy. The participant population includes English-speaking adolescents and young adults aged 13-22 years with ALL or related lymphoid malignancies being treated at Children's Hospital Los Angeles.

The main questions it aims to answer are:

  • Does the ReSeT2 intervention reduce device-measured total sedentary time (minutes/day) from baseline to Week 12 compared with usual care?
  • Does the ReSeT2 intervention improve other sedentary behavior measures, feasibility and acceptability outcomes, and exploratory health outcomes such as cardiometabolic health, quality of life, and self-efficacy?

Researchers will compare participants receiving the ReSeT2 intervention with participants receiving usual care to see if the intervention leads to greater reductions in sedentary time and improvements in related health outcomes.

Participants will:

  • Complete baseline and Week 12 assessments, including questionnaires, clinical measurements, laboratory tests, and 7-day accelerometer wear periods.
  • Be randomized to either the ReSeT2 intervention group or usual care.
  • If assigned to the intervention group:

Use a Fitbit activity tracker with inactivity prompts for 10 weeks. Receive home activity equipment and goal-based incentives. Participate in individualized coaching sessions. Participate in a peer support GroupMe chat and optional in-person group sessions.

If assigned to the usual care group, continue standard clinical care and complete study assessments.

  • Access to the internet and a smartphone compatible with Fitbit and GroupMe (participant's or parent/guardian's device).
  • Ability to participate in virtual sessions with study staff.
  • Fluent in English. (Parents/guardians do not need to be English-speaking if consent can be completed in their primary language.)

Exclusion Criteria:

  • Evidence of recurrent or metastatic disease.
  • Inability to obtain informed consent/assent.

主要结果指标

结果测量
措施说明
大体时间
Change in Total Sedentary Time
大体时间：Baseline and Week 12 (change from Baseline to Week 12).
Change from Baseline to Week 12 in average daily total sedentary time (minutes/day), measured by the ActivPAL4 thigh-worn accelerometer. Daily sedentary time will be averaged across valid wear days (defined as ≥4 days with ≥10 hours/day of waking wear time) and compared between the ReSeT2 intervention and usual care control groups. The primary analysis will compare the change from Baseline to Week 12 between study arms.
Baseline and Week 12 (change from Baseline to Week 12).
