Cannabis for Opioid Substitution Trial

Status Recruiting

Clinical Trial Summary

The purpose of this study is to define common strains of cannabis that adult chronic cancer and non-cancer pain syndrome patients are using as a replacement for opioids (narcotics). Identified strains, if any, will then be tested via randomized controlled trials to support an application for a Health Canada Drug Identification Number.

Clinical Trial Description

The search for safer alternatives to opioids for treating chronic cancer and non-cancer pain syndromes currently is an important initiative. Cannabis Research Associates (CRA) has been commissioned by Northern Green Canada Inc. to conduct a multi-phase study that will first define common strains of cannabis that patients use as a replacement for opioids, then conduct a randomized controlled trial to support an application to Health Canada for a Drug Identification Number. This protocol summarizes the methods for phase I.

In total, the Investigators plan to recruit 1,200 adult patients (> 25 years) currently using cannabis to treat chronic cancer and non-cancer pain syndromes conditions. Patients will be recruited from six pain clinics throughout Ontario. Pain clinics have not yet been identified. The study Investigators will invite licensed physicians from various private pain clinics to collaborate on this study.

This is an observational cohort study involving a mixed methods approach. Patients interested in participating will have the option to have an online survey link emailed to them so they can complete the survey at a convenient time. Or, patients can choose to complete the online survey in person with the assistance of a Research Assistant. Research Assistants will have hard copy surveys to serve as a back-up solution should they be faced with Internet connectivity and/or online survey hosting issues. No personal identifying information will be collected. Hard copy data will be stored in locked cabinets and shipped via courier to Cannabis Research Associates in batches.

All aspects of this study will be executed under the supervision of the study Investigators. Scientific independence from the sponsoring body will be maintained, and no censorship of data management, analysis, or presentation/publication will be permitted.

This study will be executed under the approval and ongoing supervision of the Research Ethics Board, as required. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
