Sertraline Augmented With GABA Agents for Cocaine Dependence
In Brief
A Phase 2 clinical trial evaluating sertraline, Placebo, and 1 other intervention for Cocaine Dependence and Depressive Symptoms. Completed, enrolled 102 participants across 1 site.
Detailed Summary
To examine the clinical efficacy of sertraline (200 mg/day) alone or sertraline in combination with gabapentin. The purpose of this study is to examine whether the antidepressant sertraline alone or combined with gabapentin delays time to relapse relative to placebo in recently abstinent cocaine-dependent volunteers who are also depressed. In addition, whether depressive symptoms or genetic factors influence treatment response to the study medications will be examined. Our hypothesis is that those on combined sertraline-gabapentin will show a longer period of abstinence than those on sertraline alone or placebo.
Study Details
Timeline
Interventions
Sertraline hydrochloride (200 mg/day) will be administered once daily. While subjects are at RCA-NLR they initially receive 50 mg/day of sertraline. This dose is gradually increased over a 3-week period until subjects receive 200 mg. When subjects are transferred to the outpatient program, they will be administered capsules once weekly, with take-home doses given in blister packs to take once a day for the rest of the week.
Placebo (cellulose or lactose) administered twice per day for 12 weeks.
Gabapentin (Neurontin; Parke-Davis; 1200 mg/day) will be administered twice daily. Initially, patients will receive 200 mg twice daily on days 1-5, 400 mg twice daily on days 6-10, then 600 mg twice daily on days 11 on. Subjects are then maintained on this dose for the duration of the trial, unless side-effects are too severe, in which case the dose of gabapentin is decreased to no less 800 mg/day. If symptoms persist, subjects' participation would then be terminated.
