Top-decile sponsor footprint

National Institute of Allergy and Infectious Diseases (NIAID) ranks in the top decile of sponsors by registered trial count (#5 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

C 68/100

1,642 of 1,802 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (91.1%), 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.

Top condition: HIV Infections (195 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.
