Brief Summary

In opioid dependent patients treated with long-acting injectable naltrexone (Vivitrol ®), we will compare the efficacy of a primary care model of counseling (Condition 1) versus individualized cognitive-behavioral psychotherapy (Condition 2) for the treatment of opioid dependence. Treatment will last 12 weeks, and participants will be given 380mg of naltrexone per injection (3 injections in total; each lasting 4 weeks). Primary outcomes will be 1) percent of opioid negative urines and 2) treatment compliance as measured by attendance and time in treatment. Secondary outcomes are opiate craving, opiate withdrawal symptoms, perceived stress scores, severity of addiction problems, and patient satisfaction. Findings will elucidate whether injectable, long-acting naltrexone would be safe and effective in a primary care setting where medication would be administered in the absence of traditional cognitive-behavioral psychotherapy and indicate whether cognitive-behavioral psychotherapy adds to treatment effects above and beyond primary care counseling. If positive, this small controlled study will provide effect size estimates for a larger trial to assess Vivitrol ® in a primary care setting.

Study Groups

1

Primary Care Counseling

Group Type: EXPERIMENTAL

Primary Care Counseling

Intervention Type: BEHAVIORAL

Subjects in this condition will attend bi-weekly 15 minute sessions with the study nurse for primary care counseling which is a brief manual-guided, medically focused counseling approach to the treatment of opioid dependent individuals seen in primary care settings. The brief counseling sessions involve repeated support for and monitoring of medication compliance, and the provision of advice regarding established methods for coping with psychological and social factors that lead to drug use.

2

Cognitive-behavioral psychotherapy (CBT)

Group Type: EXPERIMENTAL

Cognitive-behavioral psychotherapy

Intervention Type: BEHAVIORAL

Subjects in the CBT condition will participate in bi-weekly 50-minute-long individualized cognitive-behavioral psychotherapy sessions with a CBT trained clinician. The general purpose of the therapy is to: (1) acquire information about important concepts and aspects of recovery from opioid addiction; (2) increase self-awareness of specific problems and issues in relation to addiction and recovery, and (3) learn new coping skills to deal with problems contributing to or resulting from the addiction and to improve overall psychosocial functioning. The primary focus of this approach is to provide patients with frequent supportive contact and to teach cognitive-behavioral relapse prevention skills.

Eligibility Criteria

Inclusion Criteria

• Male or female individuals, ages 18 and above, meeting current diagnostic and statistical manual (DSM-IV) criteria for opioid dependence.
• Subject has voluntarily given informed consent and signed the informed consent document.

Exclusion Criteria

• Regular use of benzodiazepines.
• Psychotic or otherwise severely psychiatrically disabled (i.e., suicidal, homicidal, current mania);

• Abstinent from opiates for more than four weeks prior to naltrexone initiation.
• Medical problems that would preclude naltrexone treatment, such as laboratory evidence of significant hepato-cellular injury as evidenced by abnormal liver enzyme tests including SGOT and SGPT (> three times normal) or elevated bilirubin levels), and a history of cirrhosis.
• Women who are pregnant, nursing or refuse to use a reliable form of birth control (as assessed by pregnancy tests during initial evaluation for naltrexone, and every two weeks during the course of the study).
