Core Viewpoint - The IPO application of Maijizhi Biotechnology has not yet entered the hearing stage, raising concerns about the company's ability to successfully list and develop its core product MG-K10, an IL-4Rα antibody, amidst intense competition and patent disputes [1][2][6]. Company Overview - Maijizhi Biotechnology, founded in 2016, focuses on clinical-stage biopharmaceuticals for allergic and autoimmune diseases, with a pipeline of eight innovative candidates, the most advanced being MG-K10 [2][3]. - MG-K10 targets multiple indications, including atopic dermatitis and asthma, and is positioned as a long-acting differentiated product [2][3].

Product Development and Challenges - MG-K10's application for market approval was accepted by the NMPA on October 30, 2023, but the company has expressed uncertainty about its ability to successfully develop and commercialize the product [5][6]. - The company faces significant competition from other IL-4Rα antibodies that are either already approved or in late-stage clinical trials [3][4]. Financial Situation - Since its inception, Maijizhi has operated at a loss, with cumulative losses exceeding 800 million RMB as of March 2025, and minimal revenue generated from research services [11][12]. - The company has a cash flow crisis, with only 70.8 million RMB in cash as of March 31, 2025, while the estimated cost to complete clinical trials for MG-K10 is between 500 million to 600 million RMB [12]. Patent Issues - Maijizhi is embroiled in patent disputes with its former parent company, Sangfor Biopharma, which has filed for the invalidation of a key patent related to MG-K10 [9][10]. - The stability of the core patent is crucial for the commercial value of MG-K10, and any adverse ruling could significantly impact its market prospects [10]. Investment and Financing - The company has raised over 700 million RMB through multiple financing rounds since its establishment, with a post-money valuation increasing nearly 45 times over eight years [13]. - However, the financial structure is concerning, with a debt-to-asset ratio exceeding 100% for several years, indicating a substantial risk of insolvency [13].

Core Viewpoint - The patent dispute between Sanofi and Maij Biotechnology over the IL-4R antibody has intensified, with Sanofi applying to declare Maij's core patent invalid, which poses significant challenges for Maij as it approaches its IPO [1][2]. Group 1: Patent Dispute - The conflict began with personnel changes, as former Sanofi employees founded Maij Biotechnology and filed for IL-4R antibody patents shortly after [1]. - A court ruling in 2020 determined that the patent rights belonged to Sanofi, based on evidence of similar research proposals and experimental data from 2015 [1]. - If Sanofi's recent application to invalidate Maij's patent is successful, Maij could lose its intellectual property protection for its core product, MG-K10 [1][2]. Group 2: Financial Difficulties - Maij Biotechnology has not yet launched any products, with revenue plummeting from 8.72 million yuan in 2023 to zero in the first quarter of 2025, resulting in cumulative losses of 460 million yuan [1]. - The company's debt structure is alarming, with a debt ratio nearing 700% by the end of 2023 and still at 166.83% in March 2025, leading to negative net assets [1][2]. Group 3: Market Competition - Even if MG-K10 is successfully launched, Maij will face fierce competition in the IL-4Rα target market, which is already crowded with major players [2]. - Competitors like Sanofi and Regeneron have significant sales figures, with Dupilumab exceeding 10 billion euros, and other companies have already secured multiple indications for their products [2]. - The IL-4Rα market is expected to undergo a reshuffle between 2026 and 2027, presenting challenges such as price wars and insufficient indication coverage for Maij's MG-K10 [2][3]. Conclusion - The combination of patent disputes, financial pressures, and market competition presents significant obstacles for Maij Biotechnology's IPO journey, while Sanofi continues to strengthen its position through stable revenue and partnerships [3].
