About this study
The purpose of this study is to examine the efficacy of exercise + therapy to therapy alone to determine if they can improve the effects of prolonged exposure therapy (PE) in reducing symptoms of anxiety associated with Post-traumatic Stress Disorder (PTSD). In addition the two strategies (i.e., exercise + therapy and therapy alone condition) will be compared in terms of levels of brain-derived neurotrophic factor (BDNF). BDNF is a protein that helps to support the survival of existing neurons and stimulate the growth of new neurons and synapses. BDNF is important to learning and memory in general and therefore may be associated with the learning and memory as it relates to PE and corresponding symptoms PTSD improvement.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Prolonged Exposure and Exercise in people with Post-Traumatic Stress Disorder, run by University of Texas at Austin at 2 sites 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 4 inclusion and 6 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: finished, as of the sponsor's last update on 29 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
PTSD Symptoms (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01998100, which also lists 1 linked publication.
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 29 Dec 2015.
