About this study
Official title: Phase 2 Study of Tachikawa Project for Prevention of Posttraumatic Stress Disorder With Polyunsaturated Fatty Acid (TPOP): TPOP-01 Study
The purpose of this study is to evaluate the efficacy and safety of Polyunsaturated Fatty Acid for the prevention of Posttraumatic Stress Disorder (PTSD) in patients with accidental injuries.
Read the detailed description
Accidental injuries, mostly motor vehicle accident, in civilian population are frequent events. For instance, nearly one-third of injured patients appear to develop trauma-related psychiatric illness and the major diagnoses are post-traumatic stress disorder (PTSD) and depressive disorder. Omega-3 Polyunsaturated Fatty Acid (Omega-3 PUFA) has some evidence of efficacy of treatment in patients with anxiety and mood disorders, but no evidence of preventing anxiety and mood disorders that occur subsequent to accidental injuries. We evaluate efficacy and safety of Omega-3 PUFA for the secondary prevention of Posttraumatic Stress Disorder (PTSD) and related psychiatric illness in patients with accidental injury.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Omega-3 Polyunsaturated Fatty Acid in people with Trauma and Posttraumatic Stress Disorder, run by Japan Science and Technology Agency at 1 site in Japan.
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 10 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 3 Jul 2012. 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 Japan. 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 combined 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.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Total score of Clinician-Administrated PTSD Scale (CAPS) (time frame: Three month). 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 NCT00671489, which also lists 3 linked publications.
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 3 Jul 2012.
