Gilead and Kite Oncology Demonstrate Transformative Impact of Cell Therapy and Promise of Blood Cancer Portfolio at ASH 2022

-- New Long-Term Data Reinforce Durability of CAR T-Cell Therapy in Lymphoma and Leukemia --

-- New Real-World Evidence Shows Impact of CAR T-Cell Therapy on Patient Outcomes --

-- Updated Data From Magrolimab Studies Continue to Support Potential in MDS and AML --

FOSTER CITY, Calif. & SANTA MONICA, Calif.--()--Gilead Sciences, Inc. (Nasdaq: GILD) and Kite, a Gilead Company, will support 30 data presentations, including seven oral presentations in large B-cell lymphoma (LBCL), and two oral presentations on investigator-sponsored studies in acute myeloid leukemia (AML) during the 64th Annual American Society of Hematology (ASH) Annual Meeting (December 10-13).

“Every year, we see more patients benefitting in profound ways from CAR T-cell therapy,” said Frank Neumann, MD, PhD, Senior Vice President, Global Head of Clinical Development, Kite. “The breadth of real-world evidence and multi-year follow-up in pivotal studies we present this year can reinforce physicians’ confidence in the durability and reliability of Kite’s CAR T-cell therapies.”

Key presentations for Kite’s CAR T-cell therapies include three-year results from ZUMA-5 in indolent non-Hodgkin lymphoma (iNHL) and exploratory data from the three-year results from ZUMA-2 in mantle cell lymphoma (MCL) and two-year results from ZUMA-3 in B-cell acute lymphoblastic leukemia (ALL). Additional Kite research will focus on new sub-analyses of ZUMA-7 in LBCL, and real-world experience studying the impact of time from leukapheresis to infusion on patient outcomes.

“We continue to grow the body of evidence for new therapeutic options that improve how we treat blood cancers, which include some of the most challenging tumors,” said Bill Grossman, MD, PhD, Senior Vice President, Therapeutic Area Head, Gilead Oncology. “With our recently announced collaboration with MacroGenics to develop their second-generation CD123 bispecific antibody, we are excited about our presence at ASH and the potential of our pipeline to improve patient outcomes across a variety of hematologic cancers.”

An oral presentation showcasing results from a Phase 1/2 study of our investigational, anti-CD47 immunotherapy, in combination with azacitidine and venetoclax in patients with newly diagnosed older/unfit AML and relapsed/refractory AML also will be presented. Dates and times for accepted abstracts and presentations of note are as follows:
