In Safe Hands: Keep your Gene Therapy Program On Track
Viruses are the dominant vectors used in gene therapies. Manufacturing of viral vectors is a complex process; to avoid costly and time-consuming delays it requires the highest levels of expertise, and accuracy. Likewise, successful viral vector technology transfer requires significant know how, precision, and a methodical approach that minimizes program impact and ensures confidence around continuity of supply.
We leverage decades of viral vector contract development and manufacturing organization (CDMO) experience to ensure that every aspect of your gene therapy technology transfer is managed meticulously – from initial knowledge transfer and gap assessment through to GMP production, with regulatory support available to meet your specific needs.
Offering Fast Track and Modular frameworks to facilitate project continuity for advanced therapy developers, keep your critical production schedule on track and safeguard your supply with Charles River.
