How the National Center for Research Resources (NCRR) early-phase archive is shaped

94 indexed studies, none listed as recruiting (0% open); 91 completed (97%).

Phase mix: 8 late (III/IV) vs 20 early (I/II) (early-phase heavy).

Top condition: Osteoporosis (2 trials), 9 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.
