It is often said that cell and gene therapies are a ‘process’ rather than typical drugs. This is based on the fact that their success depends on the quality of their starting materials and how they are manufactured. This could be an autologous chimeric antigen receptor (CAR) T cell-based gene therapy, or any one of the many allogeneic products in clinical development. Manufacturing is the key strategic issue for developers of these therapies, according to speakers at the On Helix annual meeting in Cambridge, UK on 7 July.
