Detaljert beskrivelse

Leukapheresis procedure will be performed to manufacture CT103A chimeric antigen receptor (CAR) modified T cells. Bridging therapy is allowed between PBMC collection and lymphodepletion. Lymphodepletion with fludarabine and cyclophosphamide was performed for three consecutive days. After 1-day rest, subjects will receive a single dose infusion of CT103A at 1.0 x 10^6 CAR+ T cells/Kg. Subjects will be followed in the study for a minimum of 2 years after CT103A infusion. Long-term follow-up for lentiviral vector safety will be followed for up to 15 years after CT103A infusion.

  15. Subjects with any uncontrolled active infection needed to receive systemic therapy within 7 days before leukapheresis collection (excluding < CTCAE grade 2 urogenital infection and upper respiratory infection).

  16. Positive for any of the following tests:
