1,345 total trials 50 currently recruiting 1130 completed early-phase tilt top decile by trial count

GlaxoSmithKline: 1,345 sponsored US clinical trials, 50 recruiting.

GlaxoSmithKline sponsors 1,345 registered US clinical trials on ClinicalTrials.gov, 50 of them currently recruiting, and 1,130 completed. 486 of these trials are in Phase 3-4 (later-stage) and 791 in Phase 1-2 (earlier-stage). The most-studied condition in this pipeline is Pulmonary Disease, Chronic Obstructive, with 30 trials.

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.
