Summary

This is a multiple-dose study in non-treatment seeking male and female subjects with moderate to severe opioid use disorder who meet criteria from the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) to evaluate the effectiveness of RBP-6000 to block the effects of exogenous opioids.

The primary objective of this study was to demonstrate that the "Drug Liking" visual analog scale (VAS) measured after challenge with 6 mg (Dose 1) and 18 mg (Dose 2) hydromorphone was noninferior to the "Drug Liking" visual analog scale (VAS) measured after challenge with placebo at Weeks 1-4 post first injection of subcutaneous buprenorphine 300 mg (RBP-6000).

Conditions

Interventions

DRUG

Buprenorphine

A subcutaneous depot injection of buprenorphine 300 mg was delivered using the ATRIGEL® Delivery System on study days 1 and 29. As the depot degrades, buprenorphine is released into systemic circulation over an extended period of time.

DRUG

buprenorphine and naloxone

Buprenorphine and naloxone (SUBOXONE® sublingual film) is given to participants on days -14 to day -1 (the SUBOXONE sublingual film stabilization period) or as soon as they start to experience withdrawal symptoms. SUBOXONE sublingual film may be initially administered several times daily until a stable dose between 8 mg and 24 mg daily is established.

DRUG

hydromorphone

Hydromorphone IM challenges are administered during the screening period (days -17 to -15), on days -3 to -1 during the buprenorphine and naloxone (SUBOXONE sublingual film) stabilization period, and weekly during the 12-week treatment period after administration of RBP-6000. Each challenge consists of 3 days during which participants are randomly administered 0 mg (placebo), 6 mg and 18 mg hydromorphone via intramuscular (IM) injection daily in varying blinded sequences. Additionally, hydromorphone can also be earned during the afternoon Reinforcing effects tasks sessions up to the same randomized dose received in the hydromorphone challenge that morning (or money can be chosen).

DRUG

placebo

Placebo for hydromorphone administered via intramuscular injection during each challenge.
