The European Medicines agency is recommending conditional approval of Tecartus (autologous anti-CD19-transduced CD3+ cells) for the treatment of relapsed or refractory mantle cell lymphoma. The chimeric antigen receptor (CAR) T cell therapy is the third medicine of its type to be reviewed by the agency. It follows the 2018 approvals of Kymriah for leukaemia and lymphoma and Yescarta for lymphoma.
