SHENZHEN, Jan 24, 2025 – (ACN Newswire) – China Medical System Holdings Limited (the “Company”, together with its subsidiaries, the “Group” or “CMS”) is pleased to announce that on 24 January 2025, the Group through subsidiaries of the Company entered into a Collaboration Agreement with Hunan Mabgeek Biotechnology Co., Ltd. (“Mabgeek Biotechnology”) and its subsidiary for Class 1 innovative drug anti-IL-4Rα humanized monoclonal antibody injection MG-K10 (“MG-K10” or the “Product”). The Group has obtained the co-development right as specifically agreed upon in the Agreement and exclusive commercialization right to the Product in Mainland China, Hong Kong Special Administrative Region, Macao Special Administrative Region, Taiwan Region and Singapore (the “Territory”); Mabgeek Biotechnology will support the commercialization activities and is responsible for the sale and supply of the Product. The collaboration term is perpetual. IL-4Rα is considered a key target for the treatment of type 2 inflammatory diseases, such as atopic dermatitis (AD), asthma, prurigo nodularis, etc. Anti-IL-4Rα monoclonal antibodies are among the best-selling biologics in this field. MG-K10 is an innovative long-acting anti-IL-4Rα humanized monoclonal antibody that simultaneously blocks the signaling of key type 2 inflammatory cytokines IL-4 and IL-13. Following Fc mutation, MG-K10 allows long dosing interval owing to its prolonged half-life, and it is expected to be the first long-acting anti-IL-4Rα monoclonal antibody marketed in China. Currently marketed anti-IL-4Rα drugs require dosing every two weeks, whereas MG-K10 only requires dosing every four weeks, demonstrating good efficacy and safety. MG-K10 has the potential to be the Best-in-Class (BIC). This collaboration marks another significant milestone for Dermavon (formerly known as CMS Skinhealth)’s layout in the dermatology field. MG-K10 will enrich the global differentiated innovative pipeline of Dermavon, and will strongly synergize with the existing product portfolio, such as marketed innovative drug ILUMETRI (tildrakizumab injection), marketed exclusive drug Hirudoid (mucopolysaccharide polysulfate cream) and dermatology-grade skincare products of Heling soothing product series (developed for AD patients), and innovative pipeline drugs ruxolitinib cream (for the topical treatment of mild to moderate AD and non-segmental vitiligo) and povorcitinib (for the treatment of non-segmental vitiligo, hidradenitis suppurativa, prurigo nodularis and chronic spontaneous urticaria), etc. Leveraging its proven clinical development and commercialization capabilities, the Group will fully cooperate with Mabgeek Biotechnology to promote the approval of MG-K10 in China, bringing a new treatment option with lower dosing frequency, good efficacy and safety to patients with type 2 inflammatory diseases in China. More information about MG-K10 MG-K10 is a Class 1 innovative drug anti-IL-4Rα humanized monoclonal antibody injection that used for the treatment of type 2 inflammatory diseases, including AD, asthma, prurigo nodularis, allergic rhinitis, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, chronic obstructive pulmonary disease and so on. It holds substance patents in specific countries/regions within the Territory. MG-K10 has entered Phase III clinical trials in China for AD, asthma, and prurigo nodularis. In the completed Phase II clinical trials for adult moderate-to-severe AD and moderate-to-severe asthma, MG-K10 has demonstrated good efficacy and safety[1-2]. Additionally, MG-K10 has obtained IND approval for eosinophilic esophagitis, chronic rhinosinusitis with nasal polyps, and seasonal allergic rhinitis in China. According to Frost & Sullivan, the global market for treatments targeting IL-4Rα is expected to reach US$28.7 billion by 2030, with a compound annual growth rate (CAGR) of 21.8% from 2020 to 2030. In China, the market is projected to reach US$4.08 billion by 2030, with a CAGR of 76.8% from 2020 to 2030. About AD indication MG-K10’s first indication, AD, is a chronic inflammatory skin condition characterized by severe itching. It is the most burdensome non-fatal skin disease globally, with at least 230 million people affected worldwide[3]. AD is also a prevalent and high-burden chronic disease in China, with the prevalence showing an upward trend[3]. According to the Global Burden of Disease Study 2019, the number of AD patients in China increased by 25.65% from 1990 to 2019[3]. It is estimated that there are approximately 36.09 million AD patients in China[3], with approximately 9.625 million suffering from moderate-to-severe AD[4]. Current treatment options for AD primarily include topical and systemic treatments. For moderate-to-severe AD, topical medications are often insufficient to achieve disease control, necessitating the initiation of systemic treatments. However, due to the limitations in efficacy and safety of traditional systemic therapies for AD, moderate-to-severe AD patients often experience delays in systemic treatment initiation, poor compliance, and suboptimal disease control, leaving a significant unmet need in clinical practice[3]. MG-K10, with its extended dosing interval of once every four weeks, is expected to improve patient adherence and provide a new, effective, and safe systemic treatment option for patients with moderate-to-severe AD.
