03Scientific explanation
Lymphodepletion: lowers existing lymphocytes and helps CAR-T cells expand.
Early window: CRS and neurological effects are most common in the first days to weeks.
04What happens in the body?
The stages of CAR-T
After assessment and apheresis, a few days before the infusion you receive lymphodepletion, a short mild chemotherapy that "makes room" for the CAR-T cells. The infusion itself is short. For the following weeks you are watched in hospital or near the centre, because side effects usually begin in the first two weeks. Regular follow-up then continues.
