ESMO国产创新药捷报频传 市场表现却高开低走

Core Insights - The 2025 European Society for Medical Oncology (ESMO) annual meeting held in Berlin showcased significant clinical research results from various domestic pharmaceutical companies, indicating that ESMO could act as a catalyst for business development (BD) in innovative drugs from China [1][2]. Group 1: Clinical Research Highlights - Bai Li Tianheng's drug, Iza-bren, an EGFR×HER3 dual antibody ADC, received considerable attention at ESMO, with a reported 100% objective response rate (ORR) at the World Lung Cancer Conference [3]. - The overseas multi-center study of Iza-bren included 107 patients across various cancer types, showing a cORR of 55% and a median progression-free survival (mPFS) of 5.4 months, highlighting its broad-spectrum treatment potential [3][4]. - The study included a higher proportion of heavily pre-treated patients (57.9%) compared to earlier domestic studies, confirming the drug's efficacy across different populations [4]. Group 2: Market Reactions and Stock Performance - Following the ESMO conference, stocks of companies like Decipher Biosciences, Kintor Pharmaceutical, and Kelun Pharmaceutical saw significant increases after presenting their clinical data [2]. - Kintor Pharmaceutical's CAR-T therapy for pancreatic cancer showed promising results, with a 83.3% disease-free survival rate at 9 months, leading to a 7.01% increase in stock price [5][6]. Group 3: Business Development Opportunities - The ESMO meeting highlighted over 50 targets across various development paths, with a focus on "ADC+IO" and "dual/multi-antibody" therapies [7]. - Companies are increasingly focusing on differentiated mechanisms of action and complementary therapeutic areas for new BD opportunities, as traditional PD-1 targets become saturated [10]. - Recent BD agreements, such as the one between Hansoh Pharmaceutical and Roche for HS-20110, indicate a continued interest in innovative drug development, with potential milestone payments reaching up to $14.5 billion [10].
