The Food and Drug Administration (the organisation that approves new drugs and drug trials in the US) has given the go-ahead for a trial of an ‘off-the-shelf’ CAR-T cell therapy for people with lymphoma.

Current CAR-T cell therapies use T cells from the person who is going to have the therapy. These cells are collected, processed, genetically modified in a lab to recognise lymphoma cells, grown, and then given back to the person having treatment. This process can take a few weeks.

The new therapy will use CAR T cells made from donor T cells. This is called ‘allogeneic’ CAR T-cell therapy. Because the process uses donor cells, they can be collected and processed in advance, reducing the manufacturing time involved in CAR T-cell therapy. It might also be possible to use them in people who do not have enough of their own, healthy T cells to be collected.

The study is an early (phase 1) trial. It will be carried out in the US in 24 people with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma that has come back (relapsed) or has not responded (refractory) after previous treatment.
