(hereafter, Daiichi Sankyo) (TSE: 4568) reported that the Japan Ministry of Health, Labour and Welfare (MHLW) has approved Yescarta (axicabtagene ciloleucel), a chimeric antigen receptor (CAR) T-cell therapy, for the initial treatment of patients with relapsed/refractory large B-cell lymphoma ( R/R LBCL): diffuse large B-cell lymphoma, primary mediastinal large B-cell lymphoma, transformed follicular lymphoma, and high-grade B-cell lymphoma (Press release, Kite Pharma, DEC 22, 2022, View Source [SID1234625564]). Yescarta should be used only in patients who have not received prior transfusion of CAR T-cells targeted at CD19 antigen.

The Standard of Care (SOC) to treat LBCL patients has historically been a multi-step process that starts with chemoimmunotherapy, followed by high-dose chemotherapy (HDT) and then ends with a stem cell transplant (ASCT). Although approximately 60% of newly diagnosed LBCL patients will respond to the initial treatment with chemotherapy, 40% will relapse or will not respond and need second-line treatment. Yescarta is now approved for the initial treatment of R/R LBCL patients in Japan.
"We are very proud of this additional Yescarta approval in Japan," said Christi Shaw, CEO of Kite. "As Japan has the second-largest number of people diagnosed with non-Hodgkin lymphoma globally, this approval marks an important step in bringing this innovative therapy earlier to more patients."
"We are glad to have achieved this important milestone in order to provide an innovative treatment option to more patients with large B-cell lymphoma in Japan," said Wataru Takasaki, PhD, Executive Officer, Head of R&D Division in Japan, Daiichi Sankyo. "It also further demonstrates the expertise of our Daiichi Sankyo R&D organization as we had successfully expanded the indication for this CAR-T modality."
The approval of Yescarta for the initial treatment of R/R LBCL patients in Japan is based on clinical data, including the results of the global pivotal trial conducted by Kite (ZUMA-7). ZUMA-7 is the largest and longest trial of a CAR T-cell therapy versus SOC in this patient population. Results from the study demonstrated that at a median follow-up of two years, Yescarta-treated patients had a four-fold greater improvement in the primary endpoint of event-free survival (EFS; hazard ratio 0.40; 95% CI: 0.31-0.51, P<0.0001) over the current SOC (8.3 months vs 2.0 months). Additionally, Yescarta demonstrated a 2.5 fold increase in patients who were alive at two years without disease progression or need for additional cancer treatment vs SOC (41% v 16%).
This indication was first approved by the U.S. FDA in April 2022 followed by the European Commission in October 2022.
On December 7, 2022, Daiichi Sankyo and Kite jointly announced that the Marketing Authorization for Yescarta will be transferred to Gilead Sciences K.K., the Japan subsidiary of Gilead Sciences, Inc., in 2023. The Kite Cell Therapy Business Unit at Gilead Sciences K.K. will manage the sales and promotion activities of the product in Japan after the Marketing Authorization transfer.
Kite’s manufacturing facility in El Segundo, California, U.S., has been approved by Japanese regulatory authorities to commence manufacturing Yescarta for the Japan market in 2023.
About Zuma-7
ZUMA-7 is an ongoing, randomized, open-label, global, multicenter (US, Australia, Canada, Europe, Israel) Phase 3 study of 359 patients at 77 centers, evaluating the safety and efficacy of a single-infusion of Yescarta versus current SOC for second-line therapy (platinum-based salvage combination chemotherapy regimen followed by high-dose chemotherapy and autologous stem cell transplant in those who respond to salvage chemotherapy) in adult patients with relapsed or refractory LBCL within 12 months of first-line therapy. The primary endpoint is event free survival (EFS). Key secondary endpoints include objective response rate (ORR) and overall survival (OS). Additional secondary endpoints include patient reported outcomes and safety.
About YESCARTA
Yescarta (axicabtagene ciloleucel) is a CAR T-cell therapy directed against CD19 (a cell membrane protein), which harnesses a patient’s own immune system to fight cancer. Axicabtagene ciloleucel is made by removing a patient’s T cells from their blood and engineering them in the lab to express chimeric antigen receptors so that they can recognize and destroy cancer cells when they are infused back to the patient’s body. The CAR T-cell therapy is manufactured specifically for each patient and administered only once. Axicabtagene ciloleucel received Orphan Drug Designation from the Japan MHLW in 2018 for the treatment of diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, transformed follicular lymphoma and high-grade B-cell lymphoma. Yescarta was approved in Japan for the treatment of patients with relapsed or refractory large B-cell lymphomas, a type of non-Hodgkin lymphoma, in January 2021.
