HBPL Study of the Impact of the NK1 Antagonist Aprepitant

Status Completed

Clinical Trial Summary

The proposed research will focus on investigating the determinants and consequences of CAD via measurement of physiological, behavioral and subjective effects of physiologic and psychologic stress cues in CAD volunteers in the laboratory, and through examination of the effects of the effects of Aprepitant, an NK1 antagonist, on the above effects. This study will examine the effects of the above stress cues on cocaine and alcohol craving under acute Aprepitant dosing, and under placebo conditions. The study is a within-subjects crossover design using 24 subjects.

Clinical Trial Description

Non treatment seeking subjects with DSM IV cocaine and alcohol dependence were included. Subjects received double-blind acute dosing of 80 mg of aprepitant (Emend) at session start, or matched placebo. During each session subjects were exposed to one of two types of stressors, one stressor per session, presented in counterbalanced order across participants. The Physiologic stress was the cold-pressor task. Subjects immersed their hand in cold water for up to 3 minutes. The psychological stress was the Trier Social Stress Test it was completed in 25 minutes: 5 min audio taped instructions, 10 min to mentally prepare for their performance tasks, 5 min to complete a public speaking task and 5 min to complete a mental arithmetic task. Outcome measures included: Alcohol Craving measured by visual analog scale, cocaine craving measured by visual analog scale and The Multiple Choice Procedure. Each assessment was done during study screening, and then at multiple times during each study session. ;
