About this study

Official title: Efficacy of Propanolol for Treatment of Posttraumatic Stress Disorder

This study will evaluate the effectiveness of propranolol in reducing symptoms of distress in people with post-traumatic stress disorder.

Read the detailed description

Post-traumatic stress disorder (PTSD) is a common and disabling condition, with about 10% of people having experienced PTSD at some point during their lives. The diagnosis of PTSD requires certain criteria: exposure to a severe psychological trauma and the persistent presence of three symptom clusters that include re-experiencing the traumatic event, physiologic hyperarousal, and emotional numbing paired with avoidance of stimuli associated with the event. Stimuli and cues associated with the trauma, such as features of an assailant or accident site, can cause a person to re-experience the traumatic memory and associated feelings of helplessness and fear. When re-experiencing a traumatic memory, people with PTSD usually undergo a heightened stress-related hormonal response that further solidifies new stimulating associations with the traumatic memory. Treatment with propranolol, a blood pressure-lowering drug that reduces stress-related hormonal responses, may be an effective means of preventing the formation of traumatic memories and of improving PTSD symptoms. This study will evaluate the effectiveness of propranolol in reducing symptoms of distress associated with traumatic memories in people with PTSD.

Participation in this study will last 14 weeks. All potential participants will undergo a 4-hour initial visit that will begin with a medical and psychiatric history review, a psychiatric interview, and symptom questionnaires. Participants will then be assigned randomly to take a test dose of either propranolol or placebo. Upon completion of the test dose, participants will begin 14 weeks of treatment with their assigned test dose medication. Participants will be asked to take the study medication each time they have a traumatic memory associated with hyperarousal symptoms, but no more than two times a day. Using a cognitive behavioral therapy based-workbook, participants will track their symptoms daily and when they use cognitive techniques to relieve symptoms.

Participants will attend study visits every 2 weeks for the 14 weeks of treatment. During these visits, participants will describe any side effects experienced, complete interviews and questionnaires about PTSD symptom severity, review with study officials their daily workbook entries, and pick up medication. Study participation will end upon completion of the Week 14 study visit.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PropanololDrug

    Also called Inderal

    Participants will take a 40-mg dose of propranolol immediately after they experience a traumatic memory associated with strong hyperarousal symptoms. Participants may take up to two doses a day, if the doses are separated by at least 6 hours.

  • PlaceboDrug

    Participants will take a single dose of placebo immediately after they experience a traumatic memory associated with strong hyperarousal symptoms. Participants may take up to two doses a day, if the doses are separated by at least 6 hours.

  • Cognitive therapy workbookBehavioural

    Participants will also receive a cognitive behavioral therapy-based workbook in which they will track symptoms and efforts to use cognitive techniques to relieve symptoms each day.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Severity of PTSD Symptoms Measured by Clinician Administered PTSD Scale for DSM-IV (CAPS-DX)

    Scores range from 0-70, higher scores represent more severe symptoms

    Measured: Measured at Week 0, 2,4,6,8,10,12,14

Secondary outcomes (3)
  1. Change in Depression Measured by Beck Depression Inventory (BDI)

    Scores range from 0-30, higher scores represent more severe symptoms

    Measured: Measured at Weeks 0,2,4,6,8,10,12, 14

  2. Change in Post-traumatic Scale-Self Score (PS-SR)

    This is a 17-item self-report scale. Scores range from 0-51, higher scores represent more severe symptoms.

    Measured: Measured at Weeks 0,2,4,6,8,10,12, 14

  3. Change in Brief Symptoms Inventory-Short Form (BSI-SF)

    BSI-SF is an 18 item scale used for a global score of general distress. Scores range from 0-72, higher scores represent more severe symptoms

    Measured: Measured at Weeks 0,2,4,6,8,10,12, 14

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Propanolol and Cognitive therapy workbook in people with Post-Traumatic Stress Disorder, run by Weill Medical College of Cornell University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 2 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Jan 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Severity of PTSD Symptoms Measured by Clinician Administered PTSD Scale for DSM-IV (CAPS-DX) (time frame: Measured at Week 0, 2,4,6,8,10,12,14). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jan 2020.
