What participants receive

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

  • PropranololDrug

    Propranolol (tablet, oral ): 40 mg QD Day 3 and Day 21

    Intervention 1 is a single dose of prazosin administered in the presence of sertraline alone at steady state or in the presence of sertraline + brexpiprazole at steady state.

  • PrazosinDrug

    Prazosin (tablet, oral): 1 mg QD Day 2 and Day 20

    Intervention 2 is a single dose of propranolol administered in the presence of sertraline alone at steady state or in the presence of sertraline + brexpiprazole at steady state.

What is being measured

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

  1. Changes between the control and treatment periods on Day 19 vs. Day 1, Day 20 vs. Day 2, and Day 21 vs. Day 3, with prazosin or propanolol in the presence of brexpiprazole + sertraline or sertraline alone at steady state

    Mean difference in baseline-adjusted change in systolic blood pressure (ΔΔSBP), measured in mmHg, from supine to standing positions will be assessed.

    Measured: 21 days

  2. Maximum change in SBP, measured in mmHg, from supine to standing position in the presence of brexpiprazole + sertraline or sertraline alone at steady state will be assessed.

    Measured: 21 days

  3. Maximum change in diastolic blood pressure (DBP), measured in mmHg, from supine to standing position in the presence of brexpiprazole + sertraline or sertraline alone at steady state will be assessed.

    Measured: 21 days

  4. Maximum change in resting heart rate (HR), measured in beats per minute (bpm), from supine to standing position will be assessed in the presence of brexpiprazole + sertraline or sertraline alone at steady state will be assessed.

    Measured: 21 days

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted13 Jan 2022
  2. Study start7 Sep 2022
  3. Primary completion3 Aug 2023
  4. Study completion3 Aug 2023

Why it stopped: The decision to terminate the trial early was not based on safety concerns. The trial was terminated early due to some implausible blood pressure values being captured, which was the primary endpoint of the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Propranolol and Prazosin in people with Post-traumatic Stress Disorder (PTSD), run by Otsuka Pharmaceutical Development & Commercialization, Inc. 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 2 inclusion and 8 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 23 Jan 2024. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study was stopped early (reason given: The decision to terminate the trial early was not based on safety concerns. The trial was terminated early due to some implausible blood pressure values being captured, which was the primary endpoint of the study.). Results are not available in the source record.

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?

Changes between the control and treatment periods on Day 19 vs. Day 1, Day 20 vs. Day 2, and Day 21 vs. Day 3, with prazosin or propanolol in the presence of brexpiprazole + sertraline or sertraline alone at steady state (time frame: 21 days). The study lists 4 primary outcomes in all. 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 23 Jan 2024.
