Clinical Trials for Opioid Use Disorder

Area of Science:

• Clinical research
• Addiction medicine
• Pharmacotherapy

Background:

• The opioid overdose crisis necessitates accelerated research and funding for opioid use disorder (OUD).
• Existing pharmacotherapies for OUD are being augmented by novel treatment strategies.
• The opioid treatment cascade provides a framework for understanding intervention points.

Purpose of the Study:

• To provide an overview of recent and ongoing clinical trials for OUD.
• To highlight diverse therapeutic approaches, including novel compounds, formulations, and digital interventions.
• To contextualize these trials within the current OUD treatment landscape.

Main Methods:

• Review of recent clinical trial data for OUD.
• Categorization of interventions based on therapeutic modality (e.g., compounds, biologicals, digital).
• Examination of implementation strategies and trials in special populations.

Main Results:

• A wide array of compounds (cannabinoids, psychedelics) are under investigation.
• Novel strategies include vaccines, enzymes, and repurposed agents.
• New formulations, web-based interventions, and smartphone apps show promise.
• Implementation trials focus on expanding access in mainstream and specialized settings.

Conclusions:

• Clinical trials for OUD are rapidly advancing with diverse therapeutic avenues.
• Novel compounds, formulations, and digital health tools offer potential improvements.
• Implementation research is crucial for expanding treatment access to underserved populations.
