Oxytocin and Naltrexone: Investigation of Combined Effects on Stress- and Alcohol Cue-induced Craving in Alcohol Use Disorder (ON-ICE)
Oxytocin and Naltrexone: Investigation of Combined Effects on Stress- and Alcohol Cue-induced Craving in Alcohol Use Disorder - a Randomized Double-blind Placebo-controlled Parallel-group Trial
Alcohol use disorder (AUD) is a chronic relapsing disorder. Alcohol craving, a hallmark symptom of AUD that drives relapse in patients, is only insufficiently treated by existing medication. One promising new compound is Oxytocin (OXY), which showed beneficial effects on alcohol craving in preliminary clinical studies. Additionally, OXY seems to enhance effects of established medication, specifically Naltrexone (NTX), an opioid-antagonist which is approved for AUD treatment via positive synergism on neurotransmitter levels. The proposed two-armed, 1:1 randomized, double-blind, parallel group trial seeks to test the putative synergistic effects of combined intranasal OXY spray (24 IU) + oral NTX (50mg) against Placebo spray + oral NTX (50mg) on alcohol craving (primary outcome) in male and female patients with AUD that suffer from high alcohol craving, within the framework of a validated alcohol cue-and stress-exposure task (i.e. a combined Trier Stress Test and alcohol cue-exposure) that was established for screening new medications in AUD and determine their effects on craving and relapse risk. Treatment effects on additional neurobiological and biochemical markers of craving that show strong associations to individual relapse risk, will serve as secondary outcomes. Collection and analysis of follow-up data (90 days) will be performed to determine whether treatment effects relate to patient outcome.
The clinical trial period for an individual participant consists of a screening visit (visit 1), a baseline visit (visit 2) and two treatment visits (visits 3 and 4)(all within equal or less than ten days) followed by a 90 days (+/- 7 days) follow-up phase with two visits (visits 5 and 6) at day 30 (± 7 days) and day 90 (± 7 days). Visits 1 to 4 will be conducted while participants are undergoing standard in-patient treatment at the Department of Addictive Behavior and Addiction medicine at the Central Institute of Mental Health (CIMH) in Mannheim, Germany, for the medical condition under investigation.
