Summary
This was a study of the effects of VIVITROL® on alcohol cue-induced craving and the
associated brain activation patterns in alcohol-dependent adults who had recently completed
alcohol detoxification and were seeking further treatment for their alcohol dependence. The
study was powered to to detect whether VIVITROL attenuates or blocks the BOLD signal
increases in response to alcohol-related cues.
In the double-blind portion, subjects received a single administration of study drug
(VIVITROL 380 mg or placebo). Subjects who completed the double-blind portion could opt to
continue to the open-label portion and receive 2 additional months of treatment with VIVITROL
380 mg.
