Charles River Laboratories International, Inc. and Gazi University Faculty of Medicine, announced a gene therapy contract development and manufacturing organization (CDMO) collaboration, providing plasmid DNA for AAV production and in vitro efficacy studies. Hyperphosphatemic tumoral calcinosis (HTC) is a rare inherited disorder causing high blood phosphate and painful, non-cancerous calcium phosphate deposits in soft tissues, especially around joints like hips, shoulders, and elbows, leading to pain, inflammation, and movement issues. It is caused by genetic defects in regulating phosphate, and Gazi University has identified GALNT3 as the responsible gene.

Charles River will supply Gazi University with off-the-shelf research-grade AAV plasmids, offering a pre-manufactured and ready-to-use option for early-stage gene therapy programs. These plasmids are produced with animal component-free methods and are royalty-free, designed to accelerate projects and reduce costs. Committed to streamlining the development of advanced therapies from concept to cure, Charles River has established an cell and gene therapy portfolio, integrating discovery and safety assessment services, biologics testing, and pre-clinical through commercial-scale manufacturing solutions for plasmid DNA, viral vectors, and cell therapies.
