Researchers from nine academic centres, together with PACT Pharma Inc of the US, have reported data from a Phase 1 study of a novel cell therapy which produced initial signs of clinical activity in patients with a variety of solid tumours. The treatment is an allogeneic T cell receptor (TCR) T cell therapy which has been edited to recognise the patient’s specific cancer. This was done by equipping the TCR with a neoantigen specific to the cancer.
