Can a smartphone app make radiation treatment less confusing?
NCT ID NCT05173961
First seen Jun 25, 2026 · Last updated Aug 20, 2026 · Updated 3 times
Summary
This pilot study tests a mobile app called oncpatient designed to help cancer patients navigate radiation therapy. The app provides easy-to-access information about treatment logistics and side effect management. Researchers will enroll 20 adults with cancer who are about to start radiation and will check if they can download and use the app, and how helpful they find it.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- oncpatient mobile application
- What this could lead to
- If successful, this could show that a simple mobile app helps patients better understand and manage their radiation treatment.
- What could go wrong
- This is a very small pilot study with only 20 people. It only measures if people can use the app, not if it improves health outcomes.

Not a phased trial
Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18 and older. * Can read and speak English and provide informed consent. * Diagnosed with cancer, any stage, any disease site. * Must be consented to undergo a course of radiotherapy, starting within one month. No limits on duration of radiation apply. Patients must be consented prior to initiating radiotherapy, however. * Has regular access to a mobile device. * Note: This requirement unfortunately leads to the exclusion of underserved patients who cannot afford to have a mobile device. Given that the goal of this study is to establish feasibility of a mobile application, there are no true alternatives, given that these patients would require access to a mobile device if this app were commercially available. However, for impacted patients, the relevant application and resources will be made available on iPads they can access during treatment and a website they can access on any web-enabled device, to ensure they have access as much as reasonably possible. Future iterations of the application will aim to increase access to the resource however possible, but limitations will always apply due to how the core functionality of the app requires a mobile device. Exclusion Criteria: * Less than 18 years old. * Non-English speaking. * Inability to operate a mobile device.
