Top-decile sponsor footprint

Amgen ranks in the top decile of sponsors by registered trial count (#63 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 42/100

373 of 461 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (80.9%), 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 Amgen pipeline

55 recruiting of 558 indexed (10% open); 373 completed (67%).

Phase mix: 212 late (III/IV) vs 327 early (I/II) (early-phase heavy).

Top condition: Obesity (8 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.

Amgen: open-pipeline peers nationwide

Peers matched on 558 registered trials and 10% open enrollment, not the therapeutic-area sidebar.
