— Investigational KTE-X19 To Be First Chimeric Antigen Receptor (CAR) T Cell Therapy for Mantle Cell Lymphoma if Approved —
— Filing for Kite’s Second CAR T Therapy Marks Potential Expansion of Company’s Cell Therapy Portfolio —
SANTA MONICA, Calif.–(BUSINESS WIRE)–Dec. 11, 2019– Kite, a Gilead Company (Nasdaq: GILD), today announced that it has submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for the investigational chimeric antigen receptor (CAR) T cell therapy, KTE-X19, for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL).
The BLA submission is based on data from the Phase 2 ZUMA-2 trial, which demonstrated an overall response rate of 93 percent, including 67 percent with complete response, as assessed by an Independent Radiologic Review Committee (IRRC) following a single infusion of KTE-X19. In the safety analysis, Grade 3 or higher cytokine release syndrome (CRS) and neurologic events were seen in 15 percent and 31 percent of patients, respectively. No Grade 5 CRS or neurologic events occurred. Detailed findings from this trial were recently presented at the 61st American Society of Hematology (ASH) Annual Meeting & Exposition in Orlando.
“There remains a significant need for new treatments for patients with relapsed/refractory MCL despite recent advances, so this regulatory filing is an especially important milestone for the MCL community,” said Ken Takeshita, MD, Kite’s Global Head of Clinical Development. “We look forward to working with the FDA to bring KTE-X19 to appropriate patients as quickly as possible and continuing to deliver on the promise of our industry-leading cell therapy development program with a second CAR T therapy.”
