Santa Monica, Calif., – August 19, 2021 – Kite, a Gilead Company (Nasdaq: GILD), today announced the U.S. Food and Drug Administration (FDA) has cleared its Investigational New Drug (IND) application for KITE-363, the company’s first chimeric antigen receptor (CAR) T-cell therapy targeted against two antigens, CD19 and CD20. With this clearance, Kite plans to initiate a multi-center Phase 1 clinical trial evaluating KITE-363 in large B-cell lymphoma (LBCL) by the end of this year.

“CD19-directed CAR T-cell therapies have transformed outcomes for patients with relapsed or refractory large B-cell lymphomas, and we are excited to continue our research on the next generation of potential cell therapy advances for patients,” said Francesco Marincola, MD, Kite’s Senior Vice President and Global Head of Cell Therapy Research. “KITE-363 which targets two antigens highly expressed in large B-cell lymphomas – CD19 and CD20 – is the next step forward in our research that may improve current treatments to help more patients.

About KITE-363
KITE-363 is an autologous T cell therapy engineered to specifically target both CD19 and CD20. In pre-clinical studies, KITE-363 has demonstrated robust antigen-specific CAR T cell function against either target. KITE-363 is investigational and not approved anywhere globally. Its efficacy and safety have not been established.

About Large B-Cell Lymphoma (LBCL)
LBCL is an aggressive subtype of B-cell non-Hodgkin lymphoma (NHL) accounting for 30% to 40% of NHL cases with approximately 22,000 new diagnoses in the U.S. each year. About 40% of patients with LBCL will need second-line treatment, as their cancer will either relapse (return) or become refractory (not respond) to treatment. Among patients with relapsed or refractory disease, there remains an unmet need for novel therapies to further increase the durability of response.
