Exelixis ranks in the top decile of sponsors by registered trial count (#386 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 0/100

17 of 31 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (54.8%), 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.

What is open in the Exelixis pipeline

8 recruiting of 48 indexed (17% open); 17 completed (35%).

Phase mix: 11 late (III/IV) vs 37 early (I/II) (early-phase heavy).

Top condition: Renal Cell Carcinoma (4 trials), 9 others listed.

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.
