Cariprazine Effects on Brain and Behavior in Cocaine Use Disorder

September 5, 2020 updated by: Anna Rose Childress, Ph.D.

A Randomized, Single-blind, Placebo-controlled Phase II Study to Assess the Effects of Cariprazine on Brain and Behavior in Subjects With Cocaine Use Disorder

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.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Placebo Comparator: Placebo
Drug: Placebo oral capsule
PLACEBO Group: Visually identical placebo capsules will be supplied by the University of Pennsylvania Investigational Drug Service, with a dosing regimen matching the cariprazine groups.
Experimental: 1.5 mg/d cariprazine
Drug: Cariprazine Oral Capsule [Vraylar]
Cariprazine Groups (1.5 or 3mg/d): Cariprazine (VRAYLAR) capsules will be administered orally, once per day. Subjects in the 1.5mg group will receive 1 VRAYLAR capsule containing 1.5 mg cariprazine each day that study drug is administered. Subjects in the 3 mg group will be gradually titrated up to full dose: they will receive 1 VRAYLAR capsule containing 1.5mg cariprazine on the first and second days that study drug is administered and will receive 1 VRAYLAR capsule containing 3mg cariprazine each day for the rest of the medication period. The study medication period begins during the inpatient/induction phase and ends on the last day of outpatient treatment week 8 (approx. 10 weeks total). All VRAYLAR capsules will be over-encapsulated by the University of Pennsylvania Investigational Drug Services (IDS).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Primary fMRI outcome measure - BOLD signal change during visual cocaine vs. neutral cues.
Time Frame: Collected during fMRI scan 1, which takes place approximately 12-13 days after subject enrollment.
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.
Collected during fMRI scan 1, which takes place approximately 12-13 days after subject enrollment.
Primary clinical outcome measure - percentage of urines cocaine-positive or missing during outpatient phase.
Time Frame: Urines are collected 3x per week during the 8 week outpatient phase.
The primary clinical outcome is percentage of urines cocaine-positive or missing (assessed by urines positive for benzoylecgonine (BE), a metabolite of cocaine) throughout the outpatient treatment phase [Urines are counted as BE-positive if BE exceeds 300 ng/ml or if they are missing (no sample provided for a time point)].
Urines are collected 3x per week during the 8 week outpatient phase.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Secondary fMRI outcome measure - BOLD signal change during attempted inhibition of cue-triggered drug craving.
Time Frame: Collected during fMRI scan 2, which takes place approximately 13-14 days after subject enrollment.
