Charles River Launches Viral Vector Tech Transfer Program to Safeguard Gene Therapy Development

Fast Track and Modular frameworks facilitate product development continuity via seamless process transfer to the Company’s viral vector Center of Excellence

Charles River Laboratories International, Inc. (NYSE: CRL) today announced the introduction of its Modular and Fast Track viral vector technology (tech) transfer frameworks. Based on decades of viral vector contract development and manufacturing organization (CDMO) experience, the Company has designed a methodical program to drive successful, accelerated process transfer to its Maryland-based viral vector center of excellence (CoE) in as little as nine months.

Charles River’s viral vector tech transfer program offers phase-appropriate and customizable frameworks to yield exceptional stability, helping to avoid costly and time-consuming program delays. The Fast Track framework enables a streamlined approach to tech transfer when no process changes are required. The Modular framework facilitates fully customizable tech transfer for more complex scenarios when processes are not yet fully developed or process changes are required, such as switching a cell line, plasmid supply, and/or assay/analytical development, bolstered by Charles River’s premier testing platform. Both frameworks enable reliable transfer to the viral vector CoE, avoiding preventable delays and safeguarding continued program success.

With full-scale, in-house plasmid DNA and viral vector production capabilities, Charles River can efficiently manage tech transfers for a wide range of viral vectors, such as adeno-associated virus (AAV), adenovirus, lentivirus, and retrovirus. Once technology transfer has been initiated, developers gain access to Charles River’s integrated concept to cure portfolio, spanning discovery through safety assessment and commercialization.
