31 total trials 3 currently recruiting 22 completed early-phase tilt top decile by trial count

Cytokinetics: 31 sponsored US clinical trials, 3 recruiting.

Cytokinetics sponsors 31 registered US clinical trials on ClinicalTrials.gov, 3 of them currently recruiting, and 22 completed. 10 of these trials are in Phase 3-4 (later-stage) and 21 in Phase 1-2 (earlier-stage). The most-studied condition in this pipeline is Heart Failure, with 2 trials.

Top-decile sponsor footprint

Cytokinetics ranks in the top decile of sponsors by registered trial count (#526 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

F 43/100

22 of 27 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (81.5%), 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.

How open-pipeline share is computed

Recruiting share is recruiting_count divided by trial_count for this sponsor in the public registry export. Status can change between pulls; treat the figure as a research-attention snapshot, not product availability.
