A Randomized Controlled Trial of Doxazosin for Nightmares, Sleep

Status Active, not recruiting

Clinical Trial Summary

This randomized, double-blind, placebo-controlled trial of doxazosin will assess doxazosin's effectiveness for PTSD nightmares, subjective sleep quality, and non-nightmare PTSD symptoms in adult men and women veterans with full and partial-syndromal PTSD.

Clinical Trial Description

This study will involve a randomized, double-blind, placebo-controlled, flexible dose trial of doxazosin (1-10mg) for PTSD nightmares, sleep disturbance and overall PTSD symptoms. The target sample will consist of 60 male and female subjects with chronic PTSD symptoms and prominent nightmares randomly assigned to receive doxazosin (n=30) or placebo (n=30). Participants will be enrolled at the San Francisco VA Medical Center. Following baseline consent procedures, eligibility assessments, and 1-week of baseline assessments including self-report surveys, actigraphy, and at-home EEG (Sleep Profiler), all subjects will initiate doxazosin or equivalently marked placebo at 1mg at bedtime. Subjects will undergo a 4-week titration phase during which doxazosin or placebo may be increased to a maximum dose of 10mg (or equivalently marked placebo) at bedtime based on symptoms and tolerability. After the 4-week titration phase, subjects will continue at stable dose of study medication for a 4-week stable dose phase. Subjects will be asked to complete sleep diaries daily during their participation in the study. In the last week of the stable dose phase, participants will undergo an additional week of at-home sleep monitoring using actigraphy, complete end of treatment surveys, and undergo end-of-treatment clinical assessments and discontinuation of study medication. After discontinuation of study medication, participants will complete three additional days of sleep diaries. ;

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.
