Drug Interaction and Subjective Effects of Compounds for Opioid Use Disorder


Brief description of study

The overall goal of this project is to develop initial human data on effects of novel compounds on safety (interactions with oxycodone) and efficacy (subjective response to oxycodone) in non-treatment seeking opioid use disorder subjects. The compound to be studied will be the 5-HT2CR agonist lorcaserin. There are no known or reported adverse interactions between lorcaserin and oxycodone or other opioids.

Detailed Study Description

Lorcaserin is a serotonin (5-HT) 2C receptor agonist (Trade Name Belviq) approved for treatment of obesity. The study teams's preclinical research collaborators and others have shown that lorcaserin and other 5-HT2CR agonists have been shown to reduce drugs of abuse self-administration and cue reactivity in rodents including cocaine and nicotine. Recently, this data has been expanded to opioids. Rats trained to self-administer oxycodone showed a significant reduction in self-administration and oxycodone cue induced lever presses after lorcaserin administration.

This is a single center, double-blind, placebo-controlled, randomized, 1b/2a study. 18 subjects are planned. The following treatment regimens will be used:

Lorcaserin will be administered at a dose of 10mg twice daily. Placebo or Comparator - identical placebo capsules administered at the same time as lorcaserin.
