Where the data comes from, how often it refreshes, and how to go from a listing to an enrolled, compensated participant.
Trial listings come from ClinicalTrials.gov, the public registry of clinical studies maintained by the U.S. National Institutes of Health (NIH). Federal law requires most interventional studies to be registered there, which makes it the authoritative record of what is recruiting in the United States. We query the registry's public API for every metro area we cover, keep only studies with a "Recruiting" status at a site within 30 miles, and refresh the entire dataset weekly. Each listing links back to its official registry page, where you'll find the complete eligibility criteria and the study team's contact details.
Research center profiles — names, ratings, review excerpts, addresses, phone numbers and hours — are aggregated from publicly available Google Maps data for dedicated clinical research facilities in each metro. We display them so you can judge a site's reputation before you call; we have no commercial relationship with the centers listed.
Paid Clinical Trials Near Me is an independent informational directory. We are not a healthcare provider, a research sponsor, a site network or a recruitment agency. We don't conduct studies, screen participants or handle compensation. We organize public registry data around one practical question: what's recruiting near you, and what should you know before enrolling?
Compensation is set by each study's sponsor and varies enormously — by length, procedures, travel and overnight stays. The range we cite across the site ($75 to $4,500 per completed study) reflects published industry surveys of participant payments, not a promise about any specific study. The exact amount for a given trial is stated in its informed consent document before you enroll.
1) Pick a study on your metro page whose condition and age range match your profile. 2) Open its registry page and contact the study team (phone or email are listed). 3) Complete a short phone pre-screen. 4) Attend an in-person screening visit — typically with a medical history review and basic labs. 5) Review the informed consent document, which details every procedure, risk and payment. 6) Enroll. You can withdraw at any time, for any reason, and enrollment never costs anything.
Pages are generated from registry and public data, reviewed for accuracy, and dated. We don't provide medical advice, we don't accept payment for placement in listings, and we clearly separate factual registry data from our own explanatory content. Found an error?
