FDA scrutiny at Novo's Bloomington site triggers CRLs
The Bloomington plant, one of three former Catalent sites Novo acquired for $11 billion to support surging GLP-1 demand, has become a bottleneck rather than a release valve for some of its biopharma customers. As a CDMO hub, the facility provided fill/finish services for a range of partners, but repeated quality issues have resulted in an Official Action Indicated (OAI) classification and multiple complete response letters (CRLs) from the FDA.
