Study Summary

This is a phase II, randomized, single-blind, placebo-controlled study to examine whether cariprazine (1.5 or 3 mg/d) 1) alters brain and/or behavioral responses to probes of reward and inhibition and 2) decreases cocaine use in individuals with cocaine use disorder. Subjects will be tested as inpatients during fMRI sessions. After the 2-week inpatient/medication induction phase, study medication will continue for 8 outpatient weeks, during which time cocaine use will be tracked. Subjects will be monitored during a 4-wk followup phase thereafter.

Primary Outcome

The primary fMRI outcome is the extracted BOLD signal change during visual stimuli reminiscent of cocaine (i.e., cocaine cues) in an a priori circuit-level ROI.

Interventions

  • DRUG Placebo oral capsule
  • DRUG Cariprazine Oral Capsule [Vraylar]
