Trial Outcomes & Findings for Mobile Medication Adherence Platform for Buprenorphine-Naloxone During Treatment of Opioid Use Disorder: Phase I Study (NCT NCT04656899)

NCT ID: NCT04656899

Last Updated: 2023-03-14

Results Overview

Change in adherence to buprenorphine-naloxone treatment assessed by medication possession ratio (MPR). This was calculated as mean over the course of the trial. MPR is the sum of the days' supply for all fills of a given drug in a particular time period, divided by the number of days in the time period (time period varies based on length of prescription given by provider). MPR is typically expressed as a percentage, however below we express it as the result of the fraction. This measurement was based on pharmacy fills (days supply).

Measure
Pillsy Arm
Participants in the Pillsy arm will receive a prescription for buprenorphine-naloxone with an ''active'' Pillsy smart cap that will continuously collect data on pill bottle openings, missed doses, text messages sent, automated phone calls made. A participant who misses an entire day of buprenorphine-naloxone will automatically receive a survey about cravings and risk of relapse. Reminders messages to improve adherence.: If the participant does not take their medicine at the correct time, a light on the smart pill cap begins to flash. If the bottle is not opened within 20 minutes, the Pillsy application sends an SMS text reminder to the participant's phone. If the bottle is not opened within 60 minutes, the participant receives an automated phone call. The participant may also receive brief motivational phrases or craving surveys that can be tailored to participant needs and preferences. Also, based on pre-populated and adjustable craving and withdrawal levels, the participants' provider could be contacted automatically based on the thresholds being crossed. Pillsy also includes a "Pillsy Helpers" feature in which the patient can name friends and family members who will also receive a text message notification one hour after a missed dose.
Service as Usual Arm
Participants in the Service As Usual arm will receive a prescription for buprenorphine-naloxone with an ''inactive'' Pillsy smart cap that will track openings but will not provide reminders or any other messaging. They will receive a basic application that can deploy patient satisfaction surveys.

SECONDARY outcome

Timeframe: 12 weeks

Population: Participants in both groups (Pillsy and SAU) were asked by their medical provider frequently to provide urine samples as part of their standard of care treatment. This was not on a set schedule. Results of all urinalyses were provided to the research team for analysis to evaluate change in use of non-prescribed opioids over the course of the study.

Use of non-prescribed opioids is assessed via urinalysis (UA) by the treatment team at Ideal Option, as a standard of care. Ideal Option will share this data with the study team (through signed data use agreement). Our study team will evaluate change in use of non-prescribed opioids over the course of the study, based on the data provided by the clinic. Below it is expressed as the mean number of illicit opioid positive UAs submitted out of the total number of UAs submitted for each arm.
