A Pragmatic Randomized Control Trial Comparing Models of Care in the Management of Prescription Opioid Misuse


Brief description of study

This trial evaluates two standard of care treatments for opioid addiction: methadone and buprenorphine/naloxone. In order to improve patient care, the study will address real-world treatment conditions, including strict regulations for methadone dosing (i.e. initially dispensed daily at the pharmacy until stabilisation) vs. flexible take-home dosing for buprenorphine/naloxone. The OPTIMA study is designed with the intention to support patient-provider decision-making and evaluate health related outcomes with the overall aim of improving treatment outcomes through enhancing patient-centered approaches in clinical care.

Detailed Study Description

This is a multicenter, open-label, 2-arm, randomized trial with a pragmatic design involving 276 individuals with prescription opioid use disorder. Participants will be randomized to receive either:

  1. Methadone provided via initial daily witnessed ingestion as per local guidelines.
  2. Buprenorphine/naloxone maintenance therapy provided via flexible take-home dose regimens dispensed as per the physician's discretion, once clinical stability is achieved.

Once randomized to a study medication and treatment initiation and induction has begun, study physicians and participants will discuss the treatment plans and procedures going forward. Once treatment initiation has taken place, the participant will attend study visits every 2 weeks (including collection of urine samples) for the 24-week intervention period. For all study sites, standardized guidelines exist and will be adhered to for the safe induction of both medications. Frequency of illicit opioid use, intensity of craving and other secondary endpoints will also be assessed via standardized questionnaires.
