Charles River Laboratories Announces Strategic Lentiviral Vector Manufacturing Collaboration with Gates Institute at University of Colorado Anschutz Medical Campus

Charles River Laboratories International, Inc. (NYSE: CRL) and the Gates Institute at the University of Colorado Anschutz Medical Campus today announced a lentiviral vector contract development and manufacturing organization (CDMO) agreement. Gates Institute will leverage Charles River's premier cell and gene therapy CDMO expertise to develop Good Manufacturing Practice (GMP)-grade lentiviral vectors (LVVs) for use in novel chimeric antigen receptor (CAR) T-cell therapies for hematological cancers.

The Gates Institute mission at the University of Colorado Anschutz Medical Campus is to develop and deliver advanced therapies in cell and gene therapy. The Institute brings together researchers, clinicians, and a GMP biomanufacturing facility for first-in-human clinical trials. Through this strategic collaboration, Gates Institute will have access to Charles River's established manufacturing platforms and dedicated viral vector CDMO center of excellence, utilizing a range of services including process development evaluation of Gates Institute's LVV backbone, phase-appropriate research grade and High ?Quality (HQ) plasmid DNA production, and GMP LVV manufacturing. Materials produced within the collaboration will support an upcoming Investigational New Drug (IND) application for Phase I clinical trials.
