Summary of Conference Call on ADC Payload Characteristics and PD-1/VEGF Competitive Landscape Industry and Company Overview - The conference call focuses on the ADC (Antibody-Drug Conjugate) industry and the competitive landscape of PD-1/VEGF dual antibodies, particularly highlighting the advancements and strategies of companies like 康方生物 (Kangfang Biopharma), 三生制药 (3SBio), and 科利斯 (Kolis). Key Points and Arguments 1. **Impact of Payload Types on Efficacy and Adverse Reactions** Different ADC payload types significantly affect their efficacy and adverse reactions across various cancer types. Topoisomerase inhibitors perform well in breast, ovarian, and non-small cell lung cancers, while microtubule inhibitors (e.g., MAEIL) may have advantages in colorectal cancer [1][2][3]. 2. **Dual Antibody Product Classification** Dual antibody products are categorized into three types: TCE (T-cell engagers), PD-1 combined with other targets, and various dual-target combinations. TCEs are primarily used for hematological diseases, while PD-1 combinations aim to replace PD-1 monoclonal antibodies to address low response rates in cold tumors and resistance issues [4]. 3. **Leading Position of 康方生物's AK122** 康方生物's AK122 is leading in the PD-1/VEGF dual antibody field, with its clinical progress being crucial for market positioning. Other companies like 三生制药 and 科利斯 are enhancing VEGF affinity through structural modifications of Bevacizumab [1][2][5]. 4. **Clinical Trial Focus** 康方生物 is conducting clinical trials targeting late-stage lung cancer patients and gradually shifting towards first-line non-squamous non-small cell lung cancer indications. 科利斯 focuses on multi-class combination therapies involving PD-1 and VEGF [2][8]. 5. **Adverse Reaction Correlation with Payload Types** Specific adverse reactions are associated with different payload types, such as oral mucositis linked to topoisomerase inhibitors and interstitial pneumonia related to linker metabolism. Eye toxicity is primarily associated with hydrophilic microtubule inhibitors [3]. 6. **Market Activity and Innovation** The dual antibody market is highly active, with companies like 三生制药 licensing products to Pfizer. However, only a few companies, including AstraZeneca and Merck, have made significant investments in PD-1 x assets, which have shown suboptimal data performance in recent years [4][5]. 7. **Improvements by 益芯科 and 华海制药** 益芯科 and 华海制药 have made significant improvements in their VEGF-targeting products by binding VGFR1 and D2 structures, enhancing VEGF affinity, and using IgG1 structures to boost ADCC effects, potentially increasing efficacy in cold tumors [6]. 8. **AK122's Overseas Authorization and Pricing Uncertainty** AK122 is viewed as a promising product, but there is considerable uncertainty regarding its pricing and overseas authorization. The upcoming initial clinical data release on June 1 is highly anticipated to assess its potential for replicating domestic success [10]. 9. **Key Performance Indicators for Evaluation** For PD-1 inhibitors and immunotherapies, key indicators to focus on include DOR (Duration of Response) and OS (Overall Survival). For ADC chemotherapy products, ORR (Objective Response Rate) and PFS (Progression-Free Survival) trends are critical [11][12]. Additional Important Insights - The design of multi-toxin ADC products aims to enhance efficacy and increase sensitivity to another toxin, indicating a trend towards more complex therapeutic strategies [3]. - The competitive landscape is characterized by ongoing innovations and adaptations by various companies to improve therapeutic outcomes and address market needs [5][6].

Core Viewpoint - CAR-T cell therapy, while revolutionary in cancer treatment, poses potential cognitive impairment risks, such as memory loss and attention deficits, as evidenced by recent research [2][5][20]. Group 1: Research Findings - A study published in Cell confirmed that CAR-T cell therapy can lead to cognitive impairment in mouse models, revealing that the underlying issue is an immune response involving brain immune cells (microglia) [2][10]. - The research demonstrated that CAR-T cell therapy can cause persistent neuroinflammation, affecting cognitive functions across various cancer types, including blood cancers and brain tumors [10][20]. - Key findings indicated that microglial overactivation and a significant reduction (20%-35%) in oligodendrocytes, which are crucial for nerve signal transmission, contribute to cognitive decline [12][20]. Group 2: Mechanisms of Cognitive Impairment - The study identified a "cytokine storm" where inflammatory markers like CCL11 increase, leading to microglial activation and subsequent damage to oligodendrocytes [12][15]. - Cognitive deficits were linked to a 40%-50% reduction in new neurons in the hippocampus, a critical area for memory formation, explaining observed memory issues in treated mice [12][20]. - The research highlighted a vicious cycle where oligodendrocyte death impairs myelin repair, further delaying nerve signal transmission and worsening cognitive function [12][15]. Group 3: Potential Solutions - The research team proposed two strategies to mitigate cognitive damage: temporarily depleting microglia or blocking the CCR3 receptor, which showed promise in restoring cognitive function in treated mice [15][20]. - Using CSF1R inhibitors to clear overactive microglia resulted in a recovery of oligodendrocyte numbers and normalization of memory test performance [15][20]. - The study suggests personalized treatment approaches based on tumor types and the potential for combining CAR-T therapy with neuroprotective agents to enhance patient outcomes [16][20].
