SHANGHAI, June 11, 2024 (GLOBE NEWSWIRE) -- Shanghai Junshi Biosciences Co., Ltd (“Junshi Biosciences”, HKEX: 1877; SSE: 688180), a leading innovation-driven biopharmaceutical company dedicated to the discovery, development, and commercialization of novel therapies, announced that the primary endpoints of progression-free survival (“PFS,” based on independent radiographic review) and overall survival (“OS”) of a multi-center, randomized, open-label, active-controlled phase III clinical study (the “HEPATORCH study,” NCT04723004) of the company’s product, toripalimab (trade name: TUOYI?, product code: JS001), in combination with bevacizumab for the first-line treatment of advanced hepatocellular carcinoma (“HCC”) has met the pre-defined efficacy boundary. Junshi Biosciences plans to submit a supplemental new drug application (“NDA”) for this indication to the regulatory authorities in the near future.

Liver cancer is a common malignant tumor of the digestive system worldwide, and the predominant pathological type is HCC (accounting for about 90%). According to the GLOBOCAN Report for 2022, there were 866,000 new cases and 759,000 deaths from liver cancer globally that year. China in particular suffers greatly from liver cancer. The number of new liver cancer cases reached 368,000 (accounting for 42.4% of global cases) in 2022, ranking fourth in new cases among domestic malignant tumors; the numbr of deaths reached 317,000 (accounting for 41.7% of global cases), ranking second among domestic malignant tumors. Due to its insidious onset, about 70%-80% of liver cancer patients in China are already at the intermediate or advanced stage upon first diagnosis, with a median OS of approximately only 10 months and a 5-year survival rate of approximately 12%. In recent years, with the continuous emergence of the combination therapies based on the immunotherapeutic drugs, the treatment pattern of advanced liver cancer has changed, and radical cure after down-stage transformation is gradually becoming a possibility.

The HEPATORCH study is a multi-center, randomized, open-label, active-controlled phase 3 clinical study, aiming to evaluate the efficacy and safety of toripalimab in combination with bevacizumab for the first-line treatment of unresectable or metastatic HCC compared to the standard treatment of sorafenib. According to the analysis results of this study, toripalimab in combination with bevacizumab for the first-line treatment of patients with advanced HCC could significantly prolong the PFS and OS of the patients compared with sorafenib while improving the secondary endpoints such as objective response rate and time to progression. The safety profile of toripalimab was consistent with the known risks, and no new safety signals were identified. Further details will be presented at a subsequent international academic conference.
