Novartis licensed CAR-T technology -from University of Pennsylvania • Novartis to develop the CTL019 product (and other CAR-T products) • Complex supply chain:
• OXB produces GMP lentiviral vector encoding CAR targeting CD19 • White blood cells isolated from patients • Vector used to transduce expanded T-cells
• The modified T-cells are infused back into the patient` • Once inside the patient, the T-cells multiply, ‘hunt’ cancer cells and destroy them
