According to ClinicalTrials.gov-derived indexes, Mesoblast sits in the top decile of US sponsors by registered trial count (#626 of 15,742 sponsors by registered trial count).

25 total trials 1 currently recruiting 24 completed top decile by trial count

Mesoblast: 25 sponsored US clinical trials, 1 recruiting.

Mesoblast sponsors 25 registered US clinical trials on ClinicalTrials.gov, 1 of them currently recruiting, and 24 completed. 11 of these trials are in Phase 3-4 (later-stage) and 14 in Phase 1-2 (earlier-stage). The most-studied condition in this pipeline is Degenerative Disc Disease, with 2 trials.

Top-decile sponsor footprint

Mesoblast ranks in the top decile of sponsors by registered trial count (#626 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

A 90/100

24 of 24 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (100.0%), 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.

What is open in the Mesoblast pipeline

1 recruiting of 25 indexed (4% open); 24 completed (96%).

Phase mix: 11 late (III/IV) vs 14 early (I/II) (balanced across stages).

Top condition: Degenerative Disc Disease (2 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.

Mesoblast: open-pipeline peers nationwide

Peers matched on 25 registered trials and 4% open enrollment, not the therapeutic-area sidebar.
