About VA Office of Research and Development\'s Trial Portfolio
VA Office of Research and Development is a federal-government sponsor. Government-funded trials, including those from the National Institutes of Health, are typically focused on public-health priorities, rare-disease research, and questions where commercial sponsors have less incentive to fund. They are also among the most rigorously documented trials on ClinicalTrials.gov.
44 of VA Office of Research and Development's 44 registered trials are currently recruiting — roughly 100% of the portfolio. A high recruiting share usually points to an active research pipeline with multiple programs at the enrollment stage.
VA Office of Research and Development's research footprint spans Post Traumatic Stress Disorder (5 trials), Parkinson's Disease (3), and PTSD (3) as the top three conditions. The full condition list, sorted by trial count, is in the sidebar.
Not Applicable is the largest single phase in VA Office of Research and Development's portfolio at 64% of registered trials. The full phase breakdown appears in the sidebar.

How to Approach a Trial Listing
Each trial card above links to a dedicated page with the official ClinicalTrials.gov data plus a plain-English translation of the eligibility criteria. We translate technical terminology (ECOG performance status, hepatic function values, exclusionary lab thresholds) into language that a patient or caregiver can understand, but the original clinical text and the live ClinicalTrials.gov record always govern any actual eligibility decision.
Before contacting a trial site, write down questions for your treating physician using the framework on our 25 Questions guide. Discuss whether the trial fits your treatment plan, what the time commitment looks like, and whether your insurance will cover the standard-of-care portions. Trials are not a substitute for a treatment plan — they are an addition that needs medical guidance to evaluate.
Authoritative Resources
Verify any trial registration directly on ClinicalTrials.gov. For background on the FDA approval pathway that Phase 3 trials feed into, see the FDA drug approval process. For cancer-specific trial guidance, the National Cancer Institute publishes patient-oriented overviews. For global trial registrations beyond the U.S., the WHO ICTRP aggregates registries from around the world.
Frequently Asked Questions
How many clinical trials does VA Office of Research and Development have on ClinicalTrials.gov?
VA Office of Research and Development has 44 clinical trials registered on the federal ClinicalTrials.gov registry, of which 44 are actively recruiting participants right now. These counts come directly from the ClinicalTrials.gov API and are updated as the registry changes.
What conditions does VA Office of Research and Development study?
VA Office of Research and Development's registered trials cover 20 conditions on ClinicalTrials.gov, led by Post Traumatic Stress Disorder (5 trials), Parkinson's Disease (3 trials), PTSD (3 trials), Peripheral Artery Disease (3 trials), Post-traumatic Stress Disorder (PTSD) (3 trials). The complete condition list appears in the sidebar of this page; each condition links to a page listing every recruiting trial in that area, regardless of sponsor.
How do I join a VA Office of Research and Development clinical trial?
Joining a clinical trial is a medical decision that should always involve your treating physician. Each trial page on this site includes the eligibility criteria translated into plain English alongside the official clinical text, plus the contact information that the sponsor has registered with ClinicalTrials.gov. Bring the trial information to your doctor before reaching out — they can review the full inclusion and exclusion criteria against your medical history and help you decide whether to pursue screening.
What does the trial phase mean?
Phase 1 trials test safety and dosing in small groups (often 20–80 healthy volunteers or patients). Phase 2 trials evaluate efficacy and side effects in larger groups (100–300 patients with the target condition). Phase 3 trials confirm efficacy and monitor safety in the largest groups (300–3,000+ patients) and form the basis of an FDA approval submission. Phase 4 studies happen after a treatment is approved, monitoring long-term safety and effectiveness in real-world use. Some trials register without a phase — common for device, behavioral, or observational studies.
Where does this trial data come from?
All trial data is pulled directly from the ClinicalTrials.gov API v2, the official federal trial registry maintained by the National Library of Medicine at NIH. Under FDAAA 801, most U.S. drug and device trials are required to register, making ClinicalTrials.gov the most comprehensive source. Sponsors are responsible for keeping their listings current; trial status can shift between data refreshes.
