Core Insights - The report from China Post Securities highlights the potential of dual antibodies in the field of autoimmune diseases, particularly in respiratory conditions like asthma and COPD, indicating significant room for improvement in existing therapies. The market potential for TSLP class dual antibodies is viewed positively [1]. Group 1: Clinical Progress of Dual Antibodies - Sanofi's lunsekimig (TSLP/IL-13 dual antibody) has entered Phase III clinical trials, with the first patient dosed on September 24. The trials aim to enroll 1,884 patients to evaluate the efficacy and safety of lunsekimig compared to placebo in adults with eosinophilic phenotype COPD [1]. - The primary endpoint of the studies is the annualized rate of moderate to severe COPD exacerbations from baseline to week 48. The company confirmed the completion of the first patient dosing during the Q3 earnings call on October 24 [1]. Group 2: Efficacy Data and Advantages - The first-phase data for Connoa's CM512 (TSLP x IL-13 dual antibody) in atopic dermatitis (AD) showed promising results, with EASI-75 and EASI-90 response rates of 58.3% and 41.7% respectively at the 300mg dose after 12 weeks, compared to 21.4% and 0% in the placebo group. This indicates a strong potential for deep relief and sustained stability [2]. - CM512's long half-life advantage suggests that it can effectively reduce dosing frequency in clinical use, thereby improving patient compliance [2]. Group 3: Ongoing Transactions and Research Activity - On October 28, Qianxin Biotech entered a global exclusive collaboration and licensing agreement with Roche for QX031N, a long-acting dual antibody targeting TSLP and IL-33, with an upfront payment of $75 million and potential milestone payments up to $995 million. This product is expected to be developed as a new treatment option for COPD and asthma [3]. - BGI Pharma showcased the OX40L/TSLP bispecific antibody CS2015 at the 2025 ACAAI, which demonstrated therapeutic potential in preclinical trials [3].

Core Insights - The report by Zhongyou Securities focuses on the development of drugs in the autoimmune (self-immune) field, analyzing market demand, dual-antibody research priorities, and related investment targets [1][3]. Market Demand - The autoimmune field has a large patient base and long medication cycles, leading to the potential for blockbuster drugs, such as Dupilumab (Dupi), which has annual sales exceeding $10 billion. Key indications like atopic dermatitis (AD), asthma, and chronic obstructive pulmonary disease (COPD) have millions of affected patients, with nearly 9 million patients accessible to biological agents [1][2]. - Existing therapies still have unmet needs, including the need for long-acting formulations to reduce dosing frequency and improve efficacy, as well as expanding the patient population currently limited by screening criteria [1][2]. Dual-Antibody Research Focus - From the perspective of type 2 inflammation mechanisms, targets can be categorized into upstream (e.g., TSLP, IL-33) and downstream (e.g., IL-4, IL-13). Single-target monoclonal antibodies have limited efficacy, making dual antibodies an important direction due to their synergistic effects. In respiratory diseases, the TSLP×IL-13 (or IL-4R) dual antibody shows significant advantages, with clinical data indicating better reductions in FeNO and eosinophils compared to single-target drugs [2][3]. - The report emphasizes the potential of TSLP dual antibodies, highlighting leading global progress from companies like Sanofi (Lunsekimig) and Pfizer (triple antibodies), as well as domestic advancements from companies like Kangnuo (CM512) and Innovent (IBI3002) [2][3]. Investment Targets - Key investment targets include Kangnuo (CM512), which is leading in domestic progress, Innovent (IBI3002), and Qianxin Biotechnology (QX030N), with a focus on dual-antibody development [3]. Conclusion - Overall, TSLP dual antibodies in the autoimmune field show significant potential and may become the next generation of blockbuster drugs, driven by high patient numbers and unmet medical needs [1][3].
