Top-decile sponsor footprint
Ultragenyx Pharmaceutical ranks in the top decile of sponsors by registered trial count (#363 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
25 of 38 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (65.8%), 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.
Ultragenyx Pharmaceutical: open-pipeline peers nationwide
Peers matched on 52 registered trials and 8% open enrollment, not the therapeutic-area sidebar.
Ultragenyx Pharmaceutical sits at or above the median trial volume and at or above the median recruiting share among these 9 nationwide peers -- the two do not always move together.
