Bupropion For Reducing High-Risk Behaviors in Depressed Men Who Have Sex With Men (MSM)

Study Overview
=================
Brief Summary
-----------------
The primary purpose of this study was to test the whether high-risk, HIV-seronegative persons with mild-to-moderate depression would be more likely to adopt protective behavior change when provided with pharmacotherapy for their depression than when treated with placebo. High-risk behaviors include using illegal drugs and participating in unprotected sexual intercourse. The specific pharmacotherapy used in this study was the anti-depressant, bupropion. The subject population consisted of HIV negative men who have sex with men (MSM) with mild-to-moderate depression.

Detailed Description
-----------------
Depression in men is often masked by high-risk behaviors such as alcohol and drug abuse. Common symptoms among depressed men include feelings of hopelessness and helplessness, irritability, and anger. MSM are among those at highest for HIV acquisition due to high-risk behaviors, including unprotected sexual intercourse and drug abuse. Bupropion is an antidepressant medication commonly used to treat depression. The purpose of this study thus was whether bupropion could help MSM with mild-to-moderate depression reduce their high-risk behaviors. Participants in this trial were randomly assigned to receive either bupropion or placebo for 6 months. Study visits lasting approximately 2 hours each occurred at Day 0, and at Months 4, 6, and 9; included in these visits were physical examination, testing for HIV and sexually transmitted disease (STD), depression screening, and an interview-administered questionnaire inquiring into sexual activity and drug use. Shorter study visits, lasting 15 - 30 minutes each occurred at Day 15, and Months 1, 2, 4, 5, and 7, and included depression screening and physical exam.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Bupropion<br>Participants in this arm received bupropion. | Drug: Bupropion<br>* Participants initially received bupropion, 150 mg, once daily, to be taken in the morning. Dosage was increased to 150 mg twice daily within one month. Return visits were conducted monthly from study Months 1 through 6 to review medication dosage, ascertain side effects and evaluate depression severity. At the end of Moth 6, subjects were tapered to 150 mg/day over a period of 4 - 7 days. The final 150 mg/day dosage of bupropion allowed referral for pharmacotherapy without unblinding subjects or staff regarding bupropion/placebo assignment. Subjects were followed through Month 9 to permit evaluation of the durability of intervention effects.<br>* Other names: Brand name of bupropion used in the trial: Wellbutrin SR;|
| Placebo Comparator: Placebo<br>Participants in this arm received placebo that looked identical to the active comparator medication. | Drug: Placebo<br>* Participants initially received placebo, 150 mg, once daily, to be taken in the morning. Dosage was increased to 150 mg twice daily within one month. Return visits were conducted monthly from study Months 1 through 6 to review medication dosage, ascertain side effects and evaluate depression severity. At the end of Moth 6, subjects were tapered to 150 mg/day over a period of 4 - 7 days. The final 150 mg/day dosage allowed referral for pharmacotherapy without unblinding subjects or staff regarding bupropion/placebo assignment.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Number of Sexual Partners in Unprotected Anal Intercourse Reported at 6 Months Minus the Number Reported at Enrollment. | The self-reported number of partners in unprotected anal intercourse during the 3 months prior to interview as reported at the Month 6 visit minus reported at the enrollment visit. | Enrollment to Month 6 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in the Frequency Per Month of Use of Recreational Drugs Between Enrollment and Month 6 Measured by Questionnaire. | Within-individual changes in the frequency of use of recreational drugs per month in the 3 months prior to interview reported at the Month 6 visit minus that reported at the enrollment visit. | Month 6 compared to Month 0 (enrollment) | 
| Incidence of Sexually Transmitted Infections Between Study Entry and Month 6 (Measured by Questionnaire and Laboratory Testing) | Number of participants with incident sexually transmitted disease between enrollment the Month 6 interview. | Enrollment to Month 6 | 
| Change in Beck Depression Inventory - II (BDI-II) Scores Between Enrollment and Month 6. | The BDI-II is a self-administered, multiple-choice questionnaire inquiring into the presence and severity of symptoms associated with depression. BDI-II scores range from 0 to 63, with 10-19 interpreted as mild-to-moderate; 20-29 as moderate-to-severe, and ≥ 30 as severe depression. The study outcome measure was the BDI-II score at Month 6 minus the BDI score at enrollment | Month 6 compared to enrollment (Month 0) |
