Clear discovery
Organize public registry information around the questions volunteers commonly have.
Our mission
Make clinical research easier to find and understand
OpenTrials is building a patient-friendly way for volunteers and research teams to connect around clear, public study information.
The Challenge We Address
Every year, thousands of potential medical breakthroughs are delayed or halted for one simple reason: clinical trials struggle to find enough participants on time.
At the same time, millions of motivated individuals and healthy volunteers want to explore cutting-edge medical options or contribute to scientific progress, but they find traditional registry databases overwhelming and difficult to navigate.
OpenTrials.com removes these barriers. We transform complex clinical registry data into a clean, simple, and volunteer-centric search experience.
Our Role
OpenTrials.com is a completely independent, neutral marketplace directory. We do not provide medical advice, nor do we authorize medical enrollment. Instead, we act as a secure, high-speed connector — empowering volunteers to discover their options and helping researchers focus on what matters most: finding cures.
Core principles
How OpenTrials is designed to help
Four principles shape how study information, matching, and contact workflows are presented.
Geospatial precision
Use precise study-facility locations and travel preferences to improve proximity matching.
Privacy by design
Collect only what is needed, use clear consent, and protect contact information.
Inclusive network
Support people with health conditions and healthy volunteers across communities and travel needs.
Independent and neutral
OpenTrials is an independent information service. It is not affiliated with ClinicalTrials.gov, the National Institutes of Health, or the United States government. Study sponsors remain responsible for their studies.
Clear boundaries
OpenTrials does not provide medical advice, recommend treatment, determine eligibility, or authorize enrollment. Research teams make enrollment decisions.
