PACT: Cooperative Studies Program #563 - Prazosin and Combat Trauma PTSD
Study Details
Study Description
Brief Summary
Background: Posttraumatic stress disorder (PTSD) is a debilitating and disabling mental disorder that afflicts at least 25% of Veterans who have suffered life-threatening war zone trauma. Trauma-related nightmares and sleep disturbance are among the most treatment-resistant PTSD symptoms in Veterans. Increased responsiveness to central nervous system (CNS) norepinephrine (NE) contributes to the pathophysiology of overall PTSD and treatment-resistant nighttime symptoms. Placebo-controlled pilot studies demonstrate that the generically available CNS-active alpha-1 adrenoreceptor antagonist prazosin substantially reduces PTSD trauma nightmares and sleep disturbance and improves global clinical status (sense of well being and ability to function) in Veterans.
Objective: The primary objective is to demonstrate in a large multi-site placebo-controlled trial in Veterans with war zone trauma-induced PTSD that prazosin is efficacious for PTSD trauma nightmares, sleep disturbance, and global clinical status. A secondary objective is to demonstrate prazosin effectiveness for these outcome measures during clinically meaningful long-term (26 week) maintenance treatment of PTSD. The investigators will also address prazosin efficacy and long-term effectiveness for improving total PTSD symptoms, comorbid depression, quality of life, and physical functioning.
Methods: This 26 week randomized double-blind placebo-controlled study is designed to demonstrate both short term efficacy and long term effectiveness of prazosin for PTSD. The research design encompasses a shorter-term, more tightly controlled efficacy component and a longer-term, more .real world. effectiveness component. Three hundred twenty-six Veterans with war zone -related PTSD and persistent trauma nightmares will be randomized 1:1 to prazosin or placebo. Study drug will be increased using a flexible dose titration schedule based on clinical response and adverse effects to an optimum maintenance dose (1-20 mg/day). During the first 10 weeks of the study, participants will be randomized to prazosin or placebo. Previous psychotropic medications and/or psychotherapy will be maintained constant. Short term efficacy will be determined during the first 10 weeks. During the remaining 16 weeks of the 26 week trial, subjects will continue to receive stable-dose double-blind prazosin or placebo, but will have the option to receive additional psychotropic medications and/or psychotherapeutic interventions, as needed, per the judgment of the study Clinician Prescriber. It is hypothesized that prazosin will remain more clinically effective than placebo at the end of the 26-week trial, demonstrating that prazosin adds benefit over-and-above other treatments that are naturalistically administered by providers in a .real world. clinical setting.
Prazosin will be judged efficacious at 10 weeks if superior to placebo on all three primary outcome measures assessing trauma nightmares, sleep disturbance, and global clinical status: the Recurrent Distressing Dreams item of the Clinician Administered PTSD Scale (CAPS), the Pittsburgh Sleep Quality Index (PSQI), and the Clinical Global Impression of Change (CGIC). Secondary outcome measures will assess prazosin effects on total PTSD symptoms, depression, physical functioning, and quality of life. Adverse effects and cardiovascular measures, including supine and standing blood pressure (BP) and heart rate (HR) will be assessed.

Active Comparator: Prazosin Group Subjects randomized to this arm will be on prazosin. |
Drug: prazosin
Subjects will be titrated up to the optimum tolerated dose based on the Dosing Algorithm. Males and females will be titrated differently with females titrated slower and to a lower maximum daily dose. The first dose will be taken while the participant is in bed for the night to avoid orthostatic syncope, an uncommon but recognized "first dose" effect of prazosin or any alpha-1 antagonist if started at a high dose. As a further precaution, male subjects will be advised to sit on the toilet for urination at night during the first week of dose titration. The first dose effect is avoidable by starting treatment with a low dose (1 mg at bedtime) and then titrating the dose upward gradually.

Outcome Measures
Primary Outcome Measures
- CAPS Recurrent Distressing Dreams Item [This primary outcome measure was administered at baseline and week 10. The change of the 10-week from baseline was reported.]
Change from baseline in frequency and/or severity of combat trauma-related nightmares will be assessed by the CAPS Recurrent Distressing Dreams item. Possible range for Recurrent Distressing Dreams is 0-8. Higher score indicates more severe PTSD symptoms.
- Pittsburgh Sleep Quality Index (PSQI) [This primary outcome measure was administered at baseline and week 10. The change of the 10-week from baseline was reported.]
Change from baseline in possible range for PSQI global score 0-21. Higher PSQI score indicates worse quality of sleep.
- Clinical Global Impression of Change (CGIC) [This primary outcome measure was administered at baseline and week 10. The change of the 10-week from baseline was reported.]
Change from baseline in possible range for Clinical Global Impression of Change 1-7. As compared to baseline global condition, 1 is marked improvement, 2 is moderate improvement, 3 is minimal improvement, 4 is no change, 5 is minimal worsening, 6 is moderate worsening, and 7 is marked worsening.
Secondary Outcome Measures
- Pittsburgh Sleep Quality Index [This secondary outcome measure was administered at baseline, 6, 10, 14, 18, 22 and 26 weeks (or early termination).]
Change from baseline in possible range for PSQI global score 0-21. Higher PSQI score indicates worse quality of sleep.
- CAPS Recurrent Distressing Dreams Item [This secondary outcome measure was administered at baseline, 6, 10, 14, 18, 22 and 26 weeks (or early termination) to assess temporal course of changes in symptoms in response to prazosin or placebo.]
Change from baseline in frequency and/or severity of combat trauma-related nightmares will be assessed by the CAPS Recurrent Distressing Dreams item. Possible range for Recurrent Distressing Dreams is 0-8. Higher score indicates more severe PTSD symptoms.
- Clinical Global Impression of Change [This secondary outcome measure was administered at 6, 10, 14, 18, 22 and 26 weeks (or early termination).]
Change from baseline in possible range for Clinical Global Impression of Change (CGIC) 1-7. As compared to baseline global condition, 1 is marked improvement, 2 is moderate improvement, 3 is minimal improvement, 4 is no change, 5 is minimal worsening, 6 is moderate worsening, and 7 is marked worsening.
- Total CAPS Score [The total CAPS was administered at baseline, 6, 10, 18, and 26 weeks (or early termination).]
Change from baseline in possible range for CAPS total score is 0-136. Higher score indicates more severe PTSD symptoms.
- PTSD Checklist-Military Version (PCL-M) Score [This secondary outcome was administered at baseline, 6, 10, 14, 18, 22 and 26 weeks to assess change in PTSD symptom severity.]
Change from baseline in possible range for PCL-M score 17-85. Higher PCL score indicates greater propensity for chronic and delayed PTSD.
- Patient Health Questionnaire-9 (PHQ9) [This secondary outcome measure was administered at baseline, 6, 10, 14, 18, 22 and 26 weeks (or early termination).]
Change from baseline in possible range for PHQ9 score is 0-27. Higher PHQ9 score indicates more severe depression.

Arm/Group Title | Prazosin | Placebo |
---|---|---|
Arm/Group Description | Subjects randomized to this arm will be on prazosin. prazosin: Subjects will be titrated up to the optimum tolerated dose based on the Dosing Algorithm. Males and females will be titrated differently with females titrated slower and to a lower maximum daily dose. The first dose will be taken while the participant is in bed for the night to avoid orthostatic syncope, an uncommon but recognized "first dose" effect of prazosin or any alpha-1 antagonist if started at a high dose. As a further precaution, male subjects will be advised to sit on the toilet for urination at night during the first week of dose titration. The first dose effect is avoidable by starting treatment with a low dose (1 mg at bedtime) and then titrating the dose upward gradually. | Subjects randomized to this arm will be on placebo. placebo: "sugar" pill |
