Core Viewpoint - CloudTop New Horizon (1952.HK) has received IND approval for its mRNA tumor therapeutic vaccine EVM14, marking it as the first mRNA tumor vaccine to achieve dual IND approval in both China and the U.S., showcasing the company's enhanced global clinical development capabilities [1][2]. Group 1: Product Development - EVM14 is developed based on the company's proprietary mRNA technology platform and targets five tumor-associated antigens (TAA), intended for the treatment of various squamous cell carcinomas [1]. - Preclinical trials demonstrated that EVM14 induced dose-dependent antigen-specific immune responses in mice and significantly inhibited tumor growth in multiple mouse models, while also showing the ability to induce immune memory and reduce tumor recurrence [1][2]. - EVM14's combination with immune checkpoint inhibitors has been shown to significantly enhance anti-tumor activity, supporting further exploration of combination therapies in clinical settings [1][2]. Group 2: Market Potential - The targeted tumor types for EVM14 represent a significant unmet medical need, with approximately 96% of squamous non-small cell lung cancer (sq-NSCLC) patients and 97% of head and neck squamous cell carcinoma (HNSCC) patients expressing at least one of the five TAA genes [2]. - EVM14 offers advantages over traditional therapies, including no need for HLA screening, on-demand supply, lower production costs, and applicability to multiple tumor types, indicating a broad application potential in cancer treatment [2]. - The mRNA tumor vaccine market is projected to unlock hundreds of billions of dollars in potential, with the possibility of serving as a new type of cancer immunotherapy that is both broadly accessible and personalized [2]. Group 3: R&D Infrastructure - The rapid advancement of EVM14's development is supported by CloudTop New Horizon's comprehensive mRNA technology platform, which encompasses antigen design, sequence optimization, delivery system development, and large-scale production [3]. - The company holds all intellectual property rights and global interests related to its mRNA drug pipelines, including EVM14, EVM18 (CAR-T project), EVM16 (personalized tumor vaccine), and EVM15 (immunomodulatory vaccine) [3]. - EVM18 has completed several studies in non-human primates and plans to initiate clinical trials by the end of 2025, while EVM16 has started its first human clinical trial in China [3].
