Exercise and activity tracking during early treatment for children with ALL to prevent muscle loss and frailty
Official title: The PROTECT Trial Physical Activity and Exercise During Early Treatment for Children With Acute Lymphoblastic Leukaemia to Protect Against Sarcopenia and Improve Frailty Outcomes: a Pilot Randomised Controlled Trial
Run by Murdoch Childrens Research Institute · NCT07325305 · Data updated 2026-11-12
This pilot test tries a home-based physical activity and strengthening program with a Fitbit for children aged 5–17 who show early muscle weakness after starting treatment for acute lymphoblastic leukaemia to see if it prevents muscle loss and improves strength compared with usual care.

Is this trial a fit for you?
✓Likely a good fit
Ideal participants are children aged 5–17 with a new diagnosis of acute lymphoblastic leukaemia treated at the trial site who, at five weeks post-diagnosis, show signs of muscle weakness or frailty and have a caregiver with an electronic device that can link to a Fitbit.
✕Probably not a fit
Children who do not show early muscle loss are only monitored and will not receive the exercise intervention, so they are unlikely to gain direct benefit from the trial intervention.

What this trial studies
This is a pilot randomized controlled trial with a hybrid implementation design carried out at a single pediatric centre. At five weeks after diagnosis, children aged 5–17 are screened for signs of frailty and sarcopenia; those who screen positive are randomized to standard care or to a physical activity and strengthening program combined with activity tracking using a Fitbit. Children who do not show muscle loss are followed observationally to document natural recovery. The study will measure feasibility, acceptability, preliminary signals of efficacy, and variability of outcome measures to inform a larger definitive trial; optional blood sampling may be requested for mechanistic studies.
Why it matters
Potential benefit: If successful, the intervention could help preserve or restore muscle mass and strength early in ALL treatment, reducing frailty and improving recovery.
How similar studies have gone: Exercise is known to be safe and beneficial for children in general, but proactive early exercise interventions to prevent sarcopenia during initial ALL treatment are novel and not well studied.
