Trial completion reliability score

D 60/100

30 of 34 decided trials (Completed vs. Terminated on ClinicalTrials.gov) reached their planned completion (88.2%), 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 the Emergent BioSolutions early-phase archive is shaped

34 indexed studies, none listed as recruiting (0% open); 30 completed (88%).

Phase mix: 5 late (III/IV) vs 24 early (I/II) (early-phase heavy).

Top condition: Smallpox (3 trials), 4 others listed.

How to read a closed sponsor archive

When recruiting_count is zero, the indexed set is completed or otherwise not open. Phase tilt still describes where archived studies sat on the investigational pathway. Re-check ClinicalTrials.gov before acting.
