PD-(L)1/VEGF双抗走向“百家争鸣”
新财富· 2025-08-04 08:01
Core Viewpoint - The article discusses the emergence of bispecific antibodies targeting both PD-(L)1 and VEGF in cancer treatment, highlighting the approval of Ivoris monoclonal antibody as the first of its kind in China, which has sparked a wave of interest and competition in this field [2][3]. Group 1: Overview of Bispecific Antibodies - The combination of immune therapy and anti-angiogenesis drugs has shown significant clinical success, but traditional dual-drug regimens face challenges such as dosage control and side effects [2]. - Ivoris monoclonal antibody, developed by Kangfang Biopharma, is the first PD-1/VEGF bispecific antibody approved globally, marking a significant milestone in the industry [2][3]. Group 2: Competitive Landscape - Over 17 PD-(L)1/VEGF bispecific antibodies are currently in clinical trials globally, indicating a highly competitive environment with numerous companies entering the market [3]. - The competition is characterized by a diverse range of technical approaches and designs, leading to a "hundred flowers bloom" scenario in the industry [3][4]. Group 3: Key Technical Variables - Three critical variables differentiate the designs of PD-(L)1/VEGF bispecific antibodies: 1. Selection of immune targets (PD-1 vs. PD-L1), which affects the breadth of immune response and potential side effects [6]. 2. Choice of anti-angiogenesis targets (VEGF vs. VEGFR), influencing the mechanism of action and potential adverse effects [6]. 3. Antibody structure and fusion methods, which impact the drug's pharmacological properties and production processes [9]. Group 4: Representative Technical Designs - Kangfang Biopharma's Ivoris features a symmetrical tetravalent structure ("2+2 design") that enhances affinity for both PD-1 and VEGF targets, showcasing a promising design in the bispecific antibody landscape [13]. - Other companies are exploring different fusion strategies, such as C-terminal and N-terminal fusions with nanobodies, which may offer advantages in tissue penetration and efficacy [14]. Group 5: Clinical Relevance - The article emphasizes that despite theoretical advantages of various designs, the true measure of success will be clinical efficacy and safety data, as past experiences with PD-1 and PD-L1 antibodies have shown that theoretical differences do not always translate into clinical outcomes [16][17]. - The focus should remain on actual clinical results, production efficiency, and market competitiveness rather than solely on innovative structural designs [20].

Clinical Trial Results - Ivoxi's combination therapies in various cancers have shown promising results: - In MSS colorectal cancer, the combination with FOLFOXIRI achieved an ORR of 81.8% [5]. - In head and neck squamous cell carcinoma, Ivoxi alone had an ORR of 30% [5]. - PM8002 in second-line small cell lung cancer (SCLC) showed a median overall survival (mOS) of 14.3 months [6]. Future Outlook - The report suggests that the ongoing clinical trials and the development of PD-1/VEGF dual antibodies could lead to significant advancements in cancer treatment, positioning the industry for continued growth [3][4].
创新药BD热潮之后的一些思考

Group 1 - The core viewpoint of the article highlights the dual effects of the business development (BD) wave in China's innovative pharmaceutical industry, questioning whether BD is a lifeline or a chronic poison for companies [2][3] - The surge in BD transactions is driven by multiple factors, including the patent cliff crisis faced by multinational pharmaceutical companies and the accumulation of potential first-in-class (FIC) and best-in-class (BIC) pipelines by Chinese firms [2] - The total amount of BD transactions in China's innovative drug sector reached $57.1 billion in 2024, with over $50 billion in transactions occurring from early 2025 to the present [2] Group 2 - The benefits of BD are evident, including rapid cash flow acquisition, leveraging multinational resources for global development, and enhancing international recognition of Chinese innovative drugs [3] - However, there are significant concerns, such as a high return rate of 40% in BD transactions, with 25 out of 62 transactions in 2020 being terminated [3] - Companies that rely heavily on BD, like Kangfang Biotech, may face severe financial challenges if BD revenues decline, as seen with a 95% drop in 2024 [3] Group 3 - Successful companies typically possess differentiated innovation capabilities, such as Kangfang Biotech's PD-1/CTLA-4 bispecific antibody [4] - Internationalization capabilities are crucial, exemplified by BeiGene's successful entry into the U.S. market while maintaining its R&D pace [5] - A reasonable pipeline structure is also important, as demonstrated by Ascentage Pharma's high revenue-sharing ratio of 15% for Olverembatinib, potentially generating $300 million in future revenue [6] Group 4 - Companies that are merely "bare swimming" exhibit characteristics such as product homogeneity and reliance on single BD transactions, which can lead to significant market value loss [6] - The CXO companies, particularly those in contract manufacturing organizations (CMO), are clear beneficiaries of the BD trend, as they provide essential production capabilities for innovative drug projects [7] - WuXi Biologics' "CRDMO+" model allows deep involvement in the entire lifecycle of innovative drugs, ensuring continuous orders and revenue regardless of the success of BD transactions [8] Group 5 - After the BD wave subsides, only companies that can consistently produce high-quality innovative drugs and effectively commercialize them will emerge as true winners [9] - Companies must possess strong R&D capabilities and clear commercialization paths, while those relying solely on BD for funding may struggle when the tide recedes [9] - BD should be viewed as a means rather than an end, with the marathon of innovative drug development just beginning [9]
