About Tecentriq
Tecentriq is an immune checkpoint inhibitor targeting PD-L1 which is a protein expressed on tumor cells and tumor-infiltrating immune cells. PD-L1 blocks T-cell activity by binding with PD-1 and B7.1 receptors on T-cell surface. By inhibiting PD-L1, Tecentriq may enable the activation of T-cells and boost immune response against cancer cells.

In Japan, Tecentriq has been approved as a treatment of unresectable advanced/metastatic non-small cell lung cancer, extended-stage small cell lung cancer and PD-L1-positive inoperable or metastatic triple negative breast cancer. In addition, a supplemental application of Tecentriq in combination with Avastin® (bevacizumab) was submitted for the treatment of unresectable metastatic hepatocellular carcinoma to the Ministry of Health, Labour and Welfare (MHLW) and was designated as priority review by the MHLW.

In the U.S., CABOMETYX tablets are approved for the treatment of patients with advanced renal cell carcinoma (RCC) and for the treatment of patients with hepatocellular carcinoma (HCC) who have been previously treated with sorafenib. CABOMETYX tablets have also received regulatory approvals in the European Union and additional countries and regions worldwide. In Japan, the product was approved for the treatment of curatively unresectable or metastatic RCC as CABOMETYX® tablets 20mg and 60mg in March 2020 by the Ministry of Health, Labor and Welfare and launched in May 2020. In addition, a supplemental application was submitted in Japan for the treatment of unresectable HCC that has progressed following chemotherapy in January 2020.
