Efficacy of Mirtazapine in Depressed Cocaine Dependent Subjects

Completed · Phase 2 · Has a placebo group

Conditions studied: Cocaine Dependence, Depression

In brief

This research study is being done to look at the safety of the medication Mirtazapine (Remeron) in people who have cocaine dependence and depression. Hypotheses I. Cocaine usage will be less in the mirtazapine treatment group (MG) than in the control group (CG). II. A greater increase in Clinician Global Impression (CGI) score will be observed in the MG than in the CG. Secondary Hypotheses: I. A greater decrease in Hamilton Rating Scale for Depression (HAM-D) and Hamilton Rating Scale for Anxiety (HAM-A) scores will be observed in the MG than in the CG. II. A greater decrease in HIV risk behaviors will be observed in the MG than in the CG. III. A greater improvement in sleep structure will be observed in the MG than in the CG. IV. The proportion of subjects experiencing severe adverse drug reactions that necessitate termination from the study by one of the study clinicians will not differ between the MG and CG. V. Retention will be greater in MG than in CG.

• Any Axis I diagnosis that, in the opinion of the Principal Investigator, may interfere with the course of the trial.
• Physiological dependence on alcohol or opiates requiring medical detoxification.

• Known drug allergy or sensitivity to mirtazapine.
• Participation in an investigational drug or device study within 1 month of enrollment in the present study.
• Enrollment in an opiate-substitution (i.e., methadone, levo acetyl methadol (LAAM)) treatment program within 45 days of enrolling in the present study.
• Individuals having taken LAAM, methadone or naltrexone within 14 days of enrollment in the present study.
