(1) SHANGHAI, China, July 30, 2021 (GLOBE NEWSWIRE) -- Junshi Biosciences (HKEX: 1877; SSE: 688180), a leading innovation-driven biopharmaceutical company dedicated to the discovery, development and commercialization of novel therapies, announced today that the National Medical Products Administration (NMPA) of China has accepted its supplemental New Drug Application (sNDA) for toripalimab in combination with platinum-containing chemotherapy as the first-line treatment for patients with locally advanced or metastatic esophageal squamous cell carcinoma (ESCC). It is the fifth NDA submitted for toripalimab in China. The supplemental NDA is based on the JUPITER-06 study (Clinicaltrials.gov identifier: NCT03829969), which is a randomized, double-blind, placebo-controlled Phase III clinical study led by Professor Ruihua Xu from Sun Yat-sen University Cancer Center. A total of 514 patients were enrolled. The co-primary endpoints were progression-free survival (PFS) as assessed by the Blinded Independent Review Committee (BICR) and overall survival (OS). Secondary endpoints included the PFS assessed by investigator, objective response rate (ORR), disease control rate (DCR), duration of response (DOR), and safety. Based on the results of the interim analysis, the Independent Data Monitoring Committee (IDMC) determined that the co-primary endpoints of PFS and OS have crossed the prespecified efficacy boundaries and that toripalimab combined with standard chemotherapy as the first-line treatment significantly prolonged the PFS and OS of patients with advanced or metastatic ESCC, compared with placebo combined with standard chemotherapy. Data from the JUPITER-06 study will soon be presented at the 2021 ESMO Annual Meeting.
