49 total trials 19 currently recruiting 15 completed top decile by trial count

argenx: 49 sponsored US clinical trials, 19 recruiting.

argenx sponsors 49 registered US clinical trials on ClinicalTrials.gov, 19 of them currently recruiting, and 15 completed. 24 of these trials are in Phase 3-4 (later-stage) and 19 in Phase 1-2 (earlier-stage). The most-studied condition in this pipeline is Generalized Myasthenia Gravis, with 7 trials.

Top-decile sponsor footprint

argenx ranks in the top decile of sponsors by registered trial count (#380 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 27/100

15 of 20 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (75.0%), 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.
