For final product release, the identity of the final vector product must be confirmed. This testing may include the sequencing of the gene of interest, infectivity titer, genomic titer, and potency testing. Sterility, mycoplasma, and levels of endotoxin should be analyzed. In addition, characteristics of the final product should be determined, which may include vector aggregation, pH, osmolality, appearance, and particulates.

For final product release, cells for infusion must be analyzed for safety and confirmation of product specific attributes. Safety tests include sterility/bioburden, mycoplasma, and levels of endotoxin. In addition, replication competency testing may be conducted on vector-transduced cells to confirm the absence of replication competent virus. Product specific characterization testing to assess potency, identity, and purity should also be performed as appropriate to support final product release.
