Best Lentiviral Vector CDMOs by Signal Score
Lentiviral vectors are the workhorse of ex vivo gene therapy, used to engineer T cells for CAR-T and to modify hematopoietic stem cells. Because the vector ends up in patient-bound cells, manufacturers carry the regulatory weight of a critical starting material under full GMP.
Choosing a lentiviral vector CDMO comes down to BSL-2 containment, a mature suspension or adherent platform, robust analytics (titer, potency, RCL testing), and a clean regulatory record. The rankings below score each CDMO on FDA inspection history, GMP certification, clinical-program activity, and capacity signals.
FDA inspection outcomes across these CDMOs: 9 NAI (no action), 11 VAI (voluntary action), 0 OAI (official action). Leading inspection & GMP sites: UNITED KINGDOM (23), United States (20), Denmark (18), Germany (7), France (4).
