Bayer sponsors 591 registered US clinical trials on ClinicalTrials.gov, 21 of them currently recruiting, and 494 completed. 172 of these trials are in Phase 3-4 (later-stage) and 237 in Phase 1-2 (earlier-stage). The most-studied condition in this pipeline is Sunscreening Agents, with 17 trials.

Top-decile sponsor footprint

Bayer ranks in the top decile of sponsors by registered trial count (#58 of 15,742 sponsors by registered trial count). Volume at this scale usually reflects a long institutional pipeline, read phase tilt and therapeutic areas below before treating it as current-year activity.

Trial completion reliability score

D 63/100

494 of 552 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (89.5%), vs. national p10 68.4% / p90 100% among 1,234 sponsors with at least 10 decided trials. Still-open trials (Recruiting, Active-not-recruiting, Not-yet-recruiting) are excluded since they have not reached an outcome yet.
