Wrist wearable to detect opioid dosing and measure withdrawal

A Study to Train a Machine Learning Algorithm for an Evaluation of the Use of Biometric Data Captured at the Wrist for the Identification of Acute Opioid Use Events and the Quantification of Opioid Withdrawal in Opioid Dependent Individuals

Not applicable Interventional OpiAID · NCT07405398

This study will test whether a wrist-worn biometric band can detect when people with opioid use disorder take their medication and measure their withdrawal levels during medication induction.

What this trial studies

This multi-center, outpatient study will collect time-stamped biometric data from a wrist-worn device (the OpiAID Strength Band Platform™) in people starting medication for opioid use disorder with methadone or buprenorphine. Investigators will train a machine learning algorithm on patient-specific physiological signals to identify acute medication dosing events and to quantify withdrawal. The primary technical goal is to achieve at least 80% classification performance on a receiver operating characteristic curve for dosing event detection. Withdrawal quantification will be compared to time since last dose and to the SOWS in a non-inferiority analysis.

Who should consider this trial

Good fit: Adults aged 22 or older with DSM-5 opioid use disorder who are eligible for induction onto methadone or buprenorphine and who can independently operate a smartwatch and communicate in English are ideal candidates.

Not a fit: People who cannot use a wrist device (for example due to wrist tattoos or inability to operate smartwatch apps), those not undergoing MOUD induction, non-English speakers, or those with severe comorbid conditions or diminished decision-making capacity are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the platform could provide objective, continuous detection of dosing events and real-time withdrawal measurement to help clinicians tailor treatment and intervene earlier.

How similar studies have performed: Previous small studies using wearables and machine learning have shown promise for detecting substance use signals and withdrawal, but applying this approach specifically to MOUD induction with the OpiAID platform is relatively novel and not yet proven.
