Kelsey Information

Where should this trial run? It's the most expensive question in clinical research, and the evidence to answer it sits in a dozen federal databases never built to talk to each other. Joining them takes weeks nobody has, so shortlists get assembled by hand under deadline, and half of selected sites enroll one patient or none. Kelsey does the joining. Describe a protocol and Kelsey returns ranked sites with the reasoning behind each one, drawn from ClinicalTrials.gov, the NPI Registry, CMS Open Payments and other federal records. Click any number and land on the record it came from. No black box, no opinion you can't check. 200,000+ investigators and 100,000+ sites profiled across 207 countries. For sponsors and CROs: Kelsey also runs the feasibility. Study by study, indication and geography in, contract-ready shortlist out. Sites contacted, questionnaires completed, budgets scoped. If you have a study to place, message this page. For sites: your Kelsey profile is built from public federal records, the same ones a sponsor reads. If something is wrong, message this page and we will correct it. We're named after Frances Oldham Kelsey, the Canadian-born pharmacologist who withheld approval of thalidomide because the evidence was thin, and who built the modern clinical trial system in the process. Kelsey applies that standard to where trials should run. Kelsey is neutral, evidence-cited AI for clinical trial placement. We rank sites on the public evidence, and show our work. kelsey.health
