Charles River Laboratories International, Inc. and Rznomics Inc. announced a viral vector contract development and manufacturing organization (CDMO) partnership. Rznomics will leverage Charles River's viral vector CDMO experience to initiate clinical development of its RNA-based anticancer gene therapy in liver cancer patients. RZ-001 is the first ribozyme-based RNA reprogramming approach approved by the US Food and Drug Administration (FDA) for evaluation in patients.

The treatment was developed utilizing Rznomics' proprietary RNA reprogramming and editing technology and takes the form of an adenoviral vector that expresses an hTERT targeting ribozyme to treat hepatocellular carcinoma (HCC) patients. HCC is the most common type of primary liver cancer, accounting for 80% of cases worldwide. Rznomics received Phase I/IIa IND approval for RZ-001 from the FDA in October, allowing the initiation of an international clinical study in HCC patients.

Early-phase trials have also commenced in Korea following IND approval for RZ-001 from the South Korean Ministry of Food and Drug Safety (MFDS), formerly the Korea Food & Drug Administration (KFDA) in June. Charles River has standardized protocols for cell culture, transfection, and downstream purification, as well as a validated platform process with a proven track record. These high-yield, optimized methods increase speed to clinical manufacturing by reducing process development time and costs while ensuring the highest quality production.

Expanding its comprehensive cell and gene therapy portfolio to span viral vector, plasmid DNA, and cell therapy production, through the acquisitions of Vigene Biosciences, Cobra Biologics, and Cognate BioServices in 2021, Charles River offers end-to-end support and supply chain simplification for advanced therapy medical product (ATMP) developers.
