EMA validates MAA for KTE X19 for the treatment of adult patients with relapsed or refractory mantle cell lymphoma. Kite/Gilead

Kite, a Gilead Company announced that the company’s Marketing Authorization Application (MAA) for KTE X19, an investigational chimeric antigen receptor (CAR) T cell therapy for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL), has been fully validated and is now under evaluation by the European Medicines Agency (EMA). The MAA is supported by data from the single arm, open-label, Phase II 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 (median follow-up of 12.3 months). 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 during an oral session at the 61st American Society of Hematology (ASH) Annual Meeting & Exposition in Orlando.
