“CLL is an incurable disease with complex biology and immune dysregulation that has made the development of T cell-based therapies that provide deep remission very challenging,” said Anne Kerber, senior vice president, head of Cell Therapy Development, Bristol Myers Squibb. “In a population that has limited options, the TRANSCEND CLL 004 study represents the first multicenter trial evaluating a CAR T cell therapy in heavily pre-treated patients with relapsed or refractory CLL or SLL, with results showing the potential of Breyanzi as a personalized one-time treatment approach for patients with this difficult-to-treat disease.”
