Summary

This study tests three digital support programs for cancer-related fatigue. 372 adults with cancer who have moderate to severe fatigue will use a mobile app with educational content, and some will also get a self-management program based on cognitive behavioural therapy, either self-guided or with a psychologist. The goal is to see which approach best reduces fatigue burden.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
mobile app with educational content and optional self-management program based on cognitive behavioural therapy
What this could lead to
If successful, this could provide an effective, accessible digital tool to help cancer patients manage fatigue without extra clinic visits.
What could go wrong
This is a relatively early-stage trial testing different app features, so the best approach may not prove clearly better than basic education. Fatigue is subjective and results may vary.
