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.

MassBiologics: archived-pipeline peers nationwide
