Opioid safety app study pulled before it began
NCT ID NCT04462250
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aimed to develop and test a smartphone app to help patients use, store, and dispose of opioid pain medications safely. It planned to include focus groups and a small trial with a reward system. However, the study was withdrawn before enrolling any participants, so no data or conclusions are available.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Prescription Opioid Management App (smartphone application)
- What this could lead to
- If successful, this app could help people use opioid painkillers more safely and reduce the risk of misuse.
- What could go wrong
- The study was withdrawn before it started, so no results are available. It was only a small feasibility study, so even if completed, it would not prove the app works on a large scale.
