Top-decile sponsor footprint

GlaxoSmithKline ranks in the top decile of sponsors by registered trial count (#17 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 66/100

1,130 of 1,249 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (90.5%), 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.

GlaxoSmithKline: open-pipeline peers nationwide

Peers matched on 1,345 registered trials and 4% open enrollment, not the therapeutic-area sidebar.
