PTSD Clinical Trial - A Placebo-Controlled Study of Mirtazapine for PTSD

Status Completed

Clinical Trial Summary

The primary objective is to evaluate the efficacy and tolerability of mirtazapine (Remeron) in the treatment of PTSD. Primary Hypothesis to be tested: Veterans with PTSD will have improvement in their symptomatology after 8 weeks of treatment with mirtazapine compared to those treated with placebo. After completion of the placebo-controlled phase, patients who agree to continue in the study will be treated with open-label mirtazapine for an additional 8 weeks.

Clinical Trial Description

After meeting inclusion criteria, the patients enter an 8-week randomized, double-blind, placebo-controlled treatment trial of mirtazapine. After completion of the placebo-controlled phase, patients may continue study participation in an open-label mirtazapine for an additional 8 weeks.

The VA Pharmacy has an established working relationship with the investigators. The pharmacist maintains the randomization log and verifies the order for the placebo or mirtazapine (15mg) in look-a-like capsules. The investigators and patients are kept blind to the contents of the capsules until the end of the entire study. See procedure grid in attached Work Proposed Section attached. Based on symptomology and occurrence of side effects, the investigator increases the medication in 15 mg (one capsule) increments every week, as tolerated, until a maximum therapeutic benefit is achieved, not to exceed 45 mg/day (3 capsules). The dosing is at bedtime. Compliance is assessed by biweekly pill count. Patients are given supportive clinical management during the clinic visits. An investigator is available by telephone 24 hrs a day in case of emergency. Patients may be seen more often if needed. At the end of the placebo-controlled phase, if the patients agree to continue in the study (confirmed at every visit) and they have not experienced an intolerable side effect related to the study medication, the patient will stop the placebo-controlled medication and begin open label mirtazapine, starting with 15mg at bedtime and titrating as tolerated to a maximum of 60mg/day. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
