Building a Bridge of Equivalence

The number of gene therapy candidates in development is growing rapidly, with many advancing toward late-stage trials. The majority of these therapies are based on viral vector delivery. While improvements in manufacturing processes continue, manufacturers remain challenged to quickly implement new technologies for products in late-stage development or that have received approvals. A clear path for establishing equivalency is needed to facilitate more rapid advances in the field and to ultimately enable lower-cost gene therapies that reach patients faster than ever.
