How can I find a CRO with relevant clinical trial experience?
Compare 3,556 CROs and specialist trial-service providers linked to 5,950 distinct CTIS trials. Search company names and combine service, therapeutic area, phase, modality and trial-country filters. Open a company page to inspect its recorded roles and supporting studies.
How do the CRO directory filters work?
Selected categories must match within the same supporting trial. Multiple values within a category match any selected value. Results are ordered by the number of matching trials, not by a performance score.
Does every listed company provide full-service clinical trial management?
No. The directory includes CROs, specialist laboratories, technology suppliers and academic service providers. A recorded role does not prove full-service capabilities; confirm the services you need directly with each provider.
Where does the CRO experience data come from?
The dated 2026-10-09 snapshot uses public CTIS trial records. Company pages provide source links, recorded roles, study dates and available trial-level operational findings. Clear name variants are grouped; ambiguous names and legacy brands remain separate. Country tags describe study locations, and trial findings do not establish provider performance.
About this data
Recorded third-party study roles include CROs, specialist laboratories, technology suppliers and academic service providers. A listing does not imply full-service capability. Trial counts describe recorded experience, not performance rankings.
Clear company-name variants are grouped. Legacy brands and ambiguous names remain separate. Missing clinical tags are left blank. Trial findings do not establish a provider’s responsibility.
