Axitinib

SHANGHAI, China, April 24, 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 Drug Office, Department of Health, the Government of the Hong Kong Special Administrative Region (“DO”) has recently accepted the New Drug Application (“NDA”) for toripalimab in combination with cisplatin and gemcitabine for the first-line treatment of adults with metastatic or recurrent locally advanced nasopharyngeal carcinoma (“NPC”), and as a single agent for the treatment of adults with recurrent, unresectable, or metastatic NPC with disease progression on or after platinum-containing chemotherapy. The NDA is supported by results from JUPITER-02, a randomized, double-blind, placebo-controlled, multinational multi-center Phase 3 clinical study (NCT03581786) that examined toripalimab in combination with gemcitabine-cisplatin as the first-line treatment of NPC, as well as results from POLARIS-02, a multi-center, open-label, pivotal Phase 2 clinical study (NCT02915432) that evaluated toripalimab as the second-line or later treatment for recurrent or metastatic NPC. Results from JUPITER-02, the first international, multi-center, double-blind, randomized, placebo-controlled Phase 3 clinical study using immunotherapy for the treatment of NPC with the largest sample size, were presented at the plenary session of the 2021 American Society of Clinical Oncology (ASCO) annual meeting (#LBA2), and published in Nature Medicine and the Journal of the American Medical Association (JAMA). The study found that compared to chemotherapy alone, toripalimab in combination with chemotherapy for the first-line treatment of metastatic or recurrent NPC significantly improved progression-free survival (“PFS”) and overall survival (“OS”), with a median PFS of 21.4 months and a 3-year OS rate of 64.5%. Toripalimab plus chemotherapy also reduced the risk of disease progression or death by 48% and the risk of death by 37%, all while demonstrating a manageable safety profile. The POLARIS-02 results were published online in January 2021 in the Journal of Clinical Oncology. These findings showed that toripalimab demonstrated durable antitumor activity in patients with recurrent or metastatic NPC who failed previous chemotherapy, with an objective response rate (ORR) of 20.5%, a median duration of response (DoR) of 12.8 months, and a median OS of 17.4 months while maintaining a manageable safety profile. So far, toripalimab has been approved for marketing in the Chinese mainland and the US. Several NDAs are currently under regulatory review in the European Union, UK, Australia, Singapore, Malaysia and Hong Kong Special Administrative Region (“SAR”). Furthermore, NDAs for toripalimab have also been submitted in India, South Africa, Chile and Jordan. About NPC NPC is a malignant tumor that occurs in the nasopharyngeal mucosal epithelium and is one of the most common types of head and neck cancer. According to the World Health Organization, the number of newly diagnosed NPC cases in 2022 exceeded 120,000 worldwide. Due to the location of the primary tumor, surgery is rarely an option, while radiotherapy alone or in combination with chemotherapy are the main treatment options for localized cancers. About Toripalimab Toripalimab is an anti-PD-1 monoclonal antibody developed for its ability to block PD-1 interactions with its ligands, PD-L1 and PD-L2, and for enhanced receptor internalization (endocytosis function). Blocking PD-1 interactions with PD-L1 and PD-L2 promotes the immune system’s ability to attack and kill tumor cells. More than forty company-sponsored toripalimab clinical studies covering more than fifteen indications have been conducted globally by Junshi Biosciences, including in China, the United States, Southeast Asia, and Europe. Ongoing or completed pivotal clinical trials evaluating the safety and efficacy of toripalimab cover a broad range of tumor types, including cancers of the lung, nasopharynx, esophagus, stomach, bladder, breast, liver, kidney, and skin. In China, toripalimab was the first domestic anti-PD-1 monoclonal antibody approved for marketing (approved in China as TUOYI®). Currently, there are eight approved indications for toripalimab in the Chinese mainland: unresectable or metastatic melanoma after failure of standard systemic therapy;recurrent or metastatic NPC after failure of at least two lines of prior systemic therapy;locally advanced or metastatic urothelial carcinoma that failed platinum-containing chemotherapy or progressed within 12 months of neoadjuvant or adjuvant platinum-containing chemotherapy;in combination with cisplatin and gemcitabine as the first-line treatment for patients with locally recurrent or metastatic NPC;in combination with paclitaxel and cisplatin in first-line treatment of patients with unresectable locally advanced/recurrent or distant metastatic esophageal squamous cell carcinoma (ESCC);in combination with pemetrexed and platinum as the first-line treatment in EGFR mutation-negative and ALK mutation-negative, unresectable, locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC);in combination with chemotherapy as perioperative treatment and subsequently with monotherapy as adjuvant therapy for the treatment of adult patients with resectable stage IIIA-IIIB NSCLC;in combination with axitinib for the first-line treatment of patients with medium to high risk unresectable or metastatic renal cell carcinoma (RCC). The first six indications have been included in the National Reimbursement Drug List (NRDL) (2023 Edition). Toripalimab is the only anti-PD-1 monoclonal antibody included in the NRDL for the treatment of melanoma. In April 2024, the Hong Kong DO accepted the NDA for toripalimab, in combination with cisplatin and gemcitabine for the first-line treatment of adults with metastatic or recurrent locally advanced NPC, and as a single agent for the treatment of adults with recurrent, unresectable, or metastatic NPC with disease progression on or after platinum-containing chemotherapy. In the United States, the FDA has approved the Biologics License Application for toripalimab in combination with cisplatin and gemcitabine for the first-line treatment of adults with metastatic or recurrent locally advanced NPC, and for toripalimab, as a single agent, for the treatment of adults with recurrent, unresectable, or metastatic NPC with disease progression on or after platinum-containing chemotherapy in October 2023. The FDA has granted toripalimab 2 Breakthrough Therapy designations for the treatment of NPC, 1 Fast Track designation for the treatment of mucosal melanoma, and 5 Orphan Drug designations for the treatment of esophageal cancer, NPC, mucosal melanoma, soft tissue sarcoma, and small cell lung cancer (SCLC). In Europe, marketing authorization applications (MAA) were accepted by the European Medicines Agency (EMA) and the MHRA for 1) toripalimab combined with cisplatin and gemcitabine for the first-line treatment of patients with locally recurrent or metastatic NPC and 2) toripalimab combined with paclitaxel and cisplatin for the first-line treatment of patients with unresectable locally advanced/recurrent or metastatic ESCC, in December 2022 and February 2023. In Australia, Singapore and Hong Kong SAR, NDAs were accepted by the Australia Therapeutic Goods Administration (TGA), the Singapore Health Sciences Authority (HSA) and DO for toripalimab, both in combination with cisplatin and gemcitabine for the first-line treatment of adults with metastatic or recurrent locally advanced NPC, and as a single agent for the treatment of adults with recurrent, unresectable, or metastatic NPC with disease progression on or after platinum-containing chemotherapy. Toripalimab obtained an Orphan Drug designation from the TGA and a Priority Review designation from the HSA.
