• Active autoimmune disease requiring immunosuppressive therapy within 4 weeks of enrolment
• Active Graft Versus Host Disease (GVHD) requiring systemic immunosuppressive therapy within 4 weeks of enrolment
• Other concurrent malignancy or a prior malignancy treated within the past 2 years, except carcinoma in situ of the skin or cervix treated with curative intent and with no evidence of active disease
• Active (confirmed by PCR) hepatitis B or hepatitis C at time of screening confirmed by PCR
• Any Human Immunodeficiency Virus (HIV) infection at time of screening
• Hypersensitivity to fludarabine or cyclophosphamide
• Any allergy to gentamycin or its derivatives
• Treatment with any of the following in the specified time period before leukapheresis:; Allogeneic HCT within 3 months,; Autologous HCT within 3 months,; CD19 CAR-T cell infusion within 3 months,; Donor lymphocyte infusion (DLI) within 3 months,; Bendamustine within the last 6 months,; Any investigational agent within 30 days or 5 half-lives (whichever is shorter),; Systemic administration of therapeutic dose corticosteroids (>20 mg/day prednisone or equivalent for adults and ≥ 12 mg/m2/day for paediatric participants) within 7 days prior to leukapheresis; Immunosuppressive therapies (i.e., calcineurin inhibitors, methotrexate, mycophenolate, rapamycin) within 4 weeks, unless used as treatment for the B cell malignancy; Oral chemotherapy agents (i.e., venetoclax) within 5 half-lives.
