Study Summary

This trial compares the abuse potential of low-dose buprenorphine to oxycodone in healthy participants across 5 sessions. Quantitative Sensory Testing will measure pain responsiveness & drug liking to determine abuse potential.

Who is the study for?
This trial is for healthy adults aged 18-65 who can consent and have not used opioids in the last three months. It's not for those with severe mental health issues, substance use disorders, chronic pain, liver/kidney disease, seizure disorders, or recent drug use that could affect the study.Check my eligibility
What is being tested?
The study tests if low-dose buccal buprenorphine (placed between cheek and gum) has less potential for abuse compared to oral oxycodone while still providing pain relief. Participants will try different doses of buprenorphine, a placebo, and oxycodone in separate sessions.See study design
What are the potential side effects?
Buprenorphine may cause nausea, dizziness, sweating or constipation. Oxycodone can lead to similar effects plus risk of addiction. Placebos typically have no active ingredients but can sometimes cause perceived side effects.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Difference in mean maximum effect score (Emax) of the drug liking visual analog scale (VAS) between oxycodone 10 mg and an equianalgesic dose of buprenorphine
Quantitative sensory testing (QST) thermal pain tolerance in seconds
Secondary outcome measures
Difference in mean maximum effect score (Emax) of the drug liking visual analog scale between equianalgesic dose of buprenorphine and placebo conditions
Difference in mean maximum effect score (Emax) of the drug liking visual analog scale between oxycodone 10 mg and placebo conditions
