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.

How do I join a National Institute of Mental Health (NIMH) 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.

The this entity record above pulls directly from the NIH ClinicalTrials.gov registry. What follows is the per-entity context — how this entity sits in the broader U.S. clinical trials and research registries distribution and which underlying factors drive the headline numbers.
The methodology behind every numeric value on this page is publicly documented on the the NIH ClinicalTrials.gov registry portal and described in detail on this site’s methodology page. Refresh cadence varies by underlying series; the page surfaces the as-of date for each number so readers can trace any figure back to the source release.
For readers using this page as a decision input, the related-entity pages elsewhere on the site provide the comparison set. The most useful comparison for this entity is typically a peer within active and historical clinical trials with similar size, similar exposure, or similar geography — not the national-level summary alone.
