ClinicalTrials.gov ID: NCT04893525
What this study is testing
What is Buprenorphine/naloxone?
Buprenorphine/naloxone is an investigational medicine, being studied as a potential treatment for opioid-use disorder.
Also referred to as Suboxone.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This is a multi-centre, open-label RCT at four Emergency Departments (EDs) in British Columbia and Alberta. The purpose of the current study is to compare the effectiveness of buprenorphine/naloxone microdosing and standard dosing take-home induction regimens at enabling patients to successfully complete the induction regimen, and at retaining patients on opioid agonist therapy.

- Prior enrollment in the study
- Known or suspected mechanical gastrointestinal obstruction (e.g., bowel obstruction or strictures) or any diseases/conditions that affect bowel transit (e.g., ileus of any type).
- Suspected surgical abdomen (e.g., acute appendicitis or pancreatitis).
- Severe respiratory insufficiency.
- Severe CNS depression, increased cerebrospinal or intracranial pressure, and head injury.
- Complicating patient factors that make home inductions from the ED unsafe and/or that require expert consultation for consideration of induction in an observed setting. These factors include:
- Allergy to buprenorphine/naloxone
- Severe respiratory or liver dysfunction
- Concurrent withdrawal or intoxication from sedatives (e.g., alcohol, benzodiazepines)
- Active prescription for sedative medications (e.g., benzodiazepines, opioids)
- Use of monoamine oxidase inhibitors within the past 14 days
