What is CAR T-cell treatment?

In this section, you can find information about CAR T-cell therapy and its phases, alongside videos explaining different aspects of CAR T-cell treatment.

CAR T-cell therapy explained



CAR T-cell therapy is a novel form of immunotherapy to treat cancer using a patient’s own T-cells which are collected via leukapheresis or T-cells from a donor. In Europe, patients can be treated with CAR T-cell therapy as part of standard of care or by participating in a clinical trial.

Currently, only CAR T-cell therapies using patients’ own T-cells are available as standard of care to treat hematologic cancers in Europe (i.e. not as part of a clinical trial). Although often only a single infusion with CAR T-cells is needed, the treatment trajectory is intensive and consists of several treatment phases. You can read more about the phases here.

CAR T-cell therapy phases



CAR T-cell therapy consists of multiple phases, starting with an initial screening phase and ending with continued follow-ups upon going through infusion.

On this page, you can learn more about the different phases and browse through resources from various sources selected by the T2EVOLVE consortium.
