Optimal Treatment of Veterans With PTSD and Comorbid OUD

Summary

The objective of this study is to test a standard psychotherapy for PTSD in Veterans who also suffer from Opiate Use Disorder (OUD). Specifically, this study will test whether Cognitive Processing Therapy (CPT)-C is more effective in treating PTSD, compared to a control group (Individual Drug Counseling (IDC); which approximates treatment as usual), among Veterans with PTSD and comorbid OUD who are maintained on buprenorphine.

The study has three phases. In Phase I: induction to buprenorphine/naloxone (BUP/NLX) maintenance. Phase II: treatment. During this phase participants will be randomly assigned to CPT-C or IDC for 12 weeks. They will be seen weekly for psychotherapy and also regularly (weekly, then biweekly, then monthly) for buprenorphine management, symptom evaluation, and medication refill. After completing treatment participants will be referred to a buprenorphine clinic for ongoing care. Phase III: follow-up.

Approximately 160 male and female Veterans (18-65 years old) with PTSD and comorbid opiate use disorder (OUD) will be enrolled in this study. Recruitment will be through VA clinics, word-of-mouth, referrals from area programs and by advertisement. Veterans who are interested will complete a brief pre-screening and detailed in-person screening. After completing the screening process, all eligible participants will be started on buprenorphine maintenance and once withdrawal symptoms are stabilized, participants will be randomly assigned to 1 of 2 conditions (CPT-C or IDC) for 12 weeks. Veterans who are already on BUP/NLX will be allowed to participate and will start at Phase II of the study, after completing the screening.

Conditions

• Post-Traumatic Stress Disorders
• Opiate Use Disorder

Interventions

DRUG

Buprenorphine

Participants will be started at a dose of 2mg/0.5 mg BUP/NLX and this dose will be increased as needed for stabilization of opioid withdrawal symptoms up to 24 mg per day, which is standard practice.

BEHAVIORAL

Cognitive Processing Therapy (CPT)

CPT-C is a manualized, 12-session 1:1 cognitive therapy that has been designed for patients with PTSD. In this study the sessions will be conducted weekly. CPT-C uses Socratic questioning targeting distorted cognitions such as self-blame, hindsight bias, and other guilt cognitions. CPT-C is focused on the cognitive components of the therapy without exposure.

BEHAVIORAL

Individual Drug Counseling (IDC)

IDC will serve as the control group. The current standard of treatment for Veterans entering buprenorphine maintenance is to do drug counseling. Standard counseling is the primary means to achieve goals. IDC uses a semi-structured, time-limited addictions-counseling model in a 1:1 setting. The IDC manual provides an organized, concise version of what is currently practiced by most addiction counselors.
