About TrialFinderData
Find a clinical trial that fits.
What we do
TrialFinderData makes the federal clinical-trials registry easier to search for patients and caregivers looking for eligible studies near them.
We focus on U.S. clinical trials and patient eligibility. Every page on trialfinderdata.org is built from the ClinicalTrials.gov v2 API, cited and linkable so readers can trace any number back to its source.
Who runs this
TrialFinderData is built and maintained by the TrialFinder Team. We're a small group working on making public U.S. clinical trials and patient eligibility data easier for non-specialists to read. If you have a correction, a data tip, or a question about how a number was derived, the contact email below reaches us directly.
Who this is for
TrialFinderData is built for patients, caregivers, patient-advocacy groups, and clinical-research coordinators.
Why this exists
Public data on U.S. clinical trials and patient eligibility is technically free, but practically locked behind file formats, acronyms, and paywalled dashboards. TrialFinderDataexists to close that gap: take the raw federal and public-sector data, and turn it into pages a normal person can read in thirty seconds.
How we work
- Primary source only. We pull from the ClinicalTrials.gov v2 API and cite the exact dataset and version on every page.
- No invented numbers. If a figure is not in the underlying public data, it does not appear on trialfinderdata.org. We never generate synthetic statistics to fill gaps.
- Methodology, in plain English. We index every U.S.-recruiting study from the ClinicalTrials.gov v2 API, parse inclusion and exclusion criteria into a searchable eligibility profile (condition, age, sex, phase, location), and link each result to the original registry entry for full protocol detail.
- Refreshed on a schedule. Refreshed daily; new ClinicalTrials.gov postings appear in search the same day they are registered.
- Corrections welcome. Readers flag issues all the time. When the source fixes a record, TrialFinderData follows.
Known limitations
Sponsors are responsible for keeping ClinicalTrials.gov records current — some listings stay in recruiting status past actual enrollment closure. We do not verify site availability or trial funding; always confirm with the listed contact before traveling.
Why ClinicalTrials.gov needs a patient-facing home
ClinicalTrials.gov is the federal registry of every clinical trial — interventional, observational, behavioral — being conducted in the United States and many international trials. Run by the National Library of Medicine, the system contains over 450,000 historical and active trial records with detailed information on study design, eligibility criteria, locations, sponsors, and outcomes when results are reported. The registry is the authoritative federal source for trial information.
The interface is built for clinicians and clinical researchers. Patients and family members trying to find a trial for a specific condition typically need help from a hospital research coordinator to navigate the eligibility criteria and identify potentially suitable studies. TrialFinder is designed to make that search accessible without a research coordinator: every condition page lists the actively recruiting trials, filtered by phase and geography, with the eligibility criteria translated into plain English where possible.
The site does not provide medical advice or claim to replace a clinician’s judgment about trial fit. A trial that looks suitable on the page may have additional protocol-level requirements only the principal investigator can confirm. The information on each trial page is the publicly registered trial information; the next step for any specific applicant is the trial’s contact information, which connects to the study’s recruitment team directly.
How the pipeline pulls ClinicalTrials.gov data
The pipeline pulls from the ClinicalTrials.gov API on a weekly cadence. Each pull captures every active trial along with metadata: phase, sponsor type (industry, NIH, academic), location, eligibility criteria, primary and secondary outcome measures, and current recruitment status. New trials and status changes appear on the site within a week of registration.
The condition-specific pages cluster trials by therapeutic area. Phase-3 pages roll up the late-stage trials, which are the most relevant for patients searching for treatment access. Sponsor pages aggregate the trial portfolio for any specific sponsoring organization. The methodology page describes the data source and the refresh cadence in full detail.
A practical detail: the ClinicalTrials.gov registration is the trial as registered, which is not always the trial as currently being conducted. Protocol amendments happen frequently during a trial’s life; the registry tracks them but the most current operational reality is best confirmed through the trial’s contact information. The site presents the registered version with the caveat that the trial team has the most current operational information.
Where clinical trial data has caveats
Three things to know. First, eligibility criteria are written in clinical-trial-protocol language that can be hard to interpret without a clinician. The site provides plain-English summaries where possible, but for any specific applicant, a conversation with the trial’s coordinator is essential before treating eligibility as definitive.
Second, trial reporting completeness varies. Industry-sponsored trials in late phase are typically very well-documented because of regulatory requirements; investigator-initiated or early-phase trials sometimes have thinner registrations. The site shows what was registered without inferring beyond it.
Third, the registry includes both interventional and observational trials. Observational trials do not test treatments — they observe outcomes in patients receiving standard care or natural-history cohorts. For patients seeking treatment access, the relevant filter is interventional trials at the right phase. The site filters appropriately on condition and phase pages and notes the distinction on glossary entries for both trial types.
Independence
TrialFinderData is an independent publication. We are not funded, owned, or directed by any of the agencies, companies, or organizations that appear in our data. Hosting is paid for by advertising — see our Privacy Policy for details — and we do not take paid placements, sponsored rankings, or "remove-my-entry" fees.
History
TrialFinderData launched in 2026 as part of a small portfolio of independent public-data sites. It has been maintained and updated continuously since.
