SHANGHAI, China, September 25, 2023 (GLOBE NEWSWIRE) — Shanghai Junshi Biosciences Co., Ltd (\u201cJunshi Biosciences,\u201d HKEX: 1877; SSE: 688180), a leading innovation-driven biopharmaceutical company dedicated to the discovery, development, and commercialization of novel therapies, announced that the primary endpoint\u2014progression-free survival (\u201cPFS\u201d determined through independent radiological review)\u2014of a randomized, controlled, multi-center phase III clinical study (the \u201cMELATORCH study,\u201d NCT03430297) has met the pre-defined efficacy boundary. MELATORCH compares the company\u2019s product, toripalimab, with dacarbazine for the first-line treatment of unresectable or metastatic melanoma. Junshi Biosciences intends to submit a supplemental new drug application for this indication to regulatory authorities in the near future.<\/p>\n\n\n\n
Melanoma is the most malignant type of skin cancer. According to data released by GLOBOCAN 2020, in 2020, approximately 325,000 new melanoma cases and 57,000 melanoma-related deaths were recorded globally. Though melanoma is relatively uncommon in China, its mortality rate is high (5,000 deaths amongst the approximately 16,000 new cases reported in 2017) and its incidence rate is increasing year by year. In addition, the melanoma subtype that afflicts Caucasian patients in Europe and America is mainly skin type (accounting for approximately 90%), while that of patients in China are mainly acral and mucosal type (accounting for approximately 70% to 80%). Patients with these melanoma subtypes have very different pathogenesis, tumor behavior, treatment methods and prognosis. In recent years, immune checkpoint inhibitors have achieved great success in treating melanoma and have been approved in Europe and the United States for the treatment of advanced first-line, advanced second-line or later line melanoma, as well as the adjuvant treatment of melanoma. In China, however, anti-PD-1 monoclonal antibodies have only been approved for the second- or later line treatment of advanced melanoma, and the first-line treatment of advanced melanoma is still dominated by traditional chemotherapy and targeted therapy (applicable only to patients with a BRAF V600 mutation). Therefore, there is an urgent clinical need for first-line immunotherapy for patients with advanced melanoma in China.<\/p>\n\n\n\n
The MELATORCH study is China\u2019s first pivotal registrational clinical study of PD-(L)1 inhibitor for first-line treatment of advanced melanoma that produced positive results. These results showed that compared with dacarbazine, toripalimab as the first-line treatment for unresectable or metastatic melanoma significantly prolonged the PFS of patients. Toripalimab demonstrated a safety profile consistent with its safety profiles observed in prior studies, and no new safety signals were identified. The details of this study will be presented at an upcoming international academic conference.<\/p>\n\n\n\n
\u201cThrough our Phase II study, POLARIS-01, we confirmed the efficacy and safety of toripalimab as a treatment for patients with second- and later line melanoma,\u201d said MELATORCH\u2019s principal investigator, Professor Jun GUO of Peking University Cancer Hospital. \u201cNow, with the success of the MELATORCH study, the benefits of toripalimab may reach first-line melanoma patients as well. Compared to traditional chemotherapy drugs, patients treated with toripalimab monotherapy experienced improved PFS. Patients with different melanoma subtypes were also able to benefit from the treatment, an observation consistent with the findings of POLARIS-01. We are enthusiastic about the prospect of more melanoma patients benefiting from our high-quality, innovative and domestically produced drug.\u201d <\/p>\n\n\n\n
Dr. Jianjun ZOU, Global Research and Development President of Junshi Biosciences, also shares her excitement. \u201cThanks to our nation\u2019s accelerated review and approval policy for new drugs, in December 2018, toripalimab received conditional approval for the second- and later line treatment of advanced melanoma, based on its Phase II clinical trial. This approval bridged the gap in domestic anti-PD-1 monoclonal antibodies and made immunotherapy more accessible and affordable for many Chinese cancer patients. 5 years later, we have continued building on our past achievements in the field of melanoma treatment, and conducted a Phase III confirmatory study that demonstrates once more the robust efficacy of toripalimab. We will maintain close communication with regulatory authorites to expedite the indication registration process and make toripalimab available for usage as soon as possible.\u201d<\/p>\n\n\n\n
