- The company has established a comprehensive ActRII portfolio and is in discussions with potential partners for strategic cooperations to accelerate development and commercialization of the ActRII portfolio - First-in-human study of LAE102(ActRIIA mAb) demonstrated encouraging safety and efficacy profile, preliminary results of Phase I MAD study in China and U.S. Phase 1 clinical trial expected in H2 2025 - To complete subject enrollment of Phase III clinical trial in breast cancer for LAE002(afuresertib) in Q4 2025, NDA submission to CDE expected in H1 2026 Aug 14, 2025 — Laekna, Inc. (2105.HK), a clinical-stage biotechnology company, announced the unaudited condensed consolidated interim results for the six months ended June 30, 2025, highlighting its significant progress in the research and development of metabolic diseases and cancer assets, as well as its global collaborations with strategic partners. “At the 85th scientific sessions of the American Diabetes Association (ADA), the Phase II clinical data of Bimagrumab and the preclinical study results of our ActRII portfolio strongly validated the druggability of the ActRII pathway in muscle regeneration and fat mass reduction”, said Dr. Chris Lu, Chairman and CEO of Laekna. “In the second half of 2025, the anticipated data readout of Phase I MAD study in China and U.S. Phase I clinical trial of LAE102 (ActRIIA monoclonal antibody), combined with the initiation of human study for LAE103 (ActRIIB monoclonal antibody), we expect to achieve more validations of the individual and synergistic mechanisms of action of these two receptor subtypes (ActRIIA/B). This represents a key focus area for the entire industry, particularly among global leaders in the weight-loss therapeutics area.” Dr. Chris Lu further highlighted the potential of Laekna’s oncology assets: “We target to complete subject enrollment of our Phase III clinical trial of LAE002 (afuresertib) for breast cancer in Q4 2025. This poises LAE002 (afuresertib) to be the first domestically developed AKT inhibitor in China. We are fully committed to accelerating the NDA submission and commercialization of LAE002(afuresertib) to bring this precision therapy to patients who are in need of novel treatment options.” He emphasized that, during the first half of 2025, a remarkable new wave of upswing is upfolding in China’s innovative pharmaceutical sector, and Laekna will actively engage in the global wave of innovation with ambition, resilience, and solid execution to further demonstrate our value. Metabolic diseases: established a comprehensive ActRII portfolio, LAE102 in-human study demonstrated encouraging safety and efficacy profile Blocking Activin-ActRII pathway could promote muscle regeneration and fat mass reduction. This positions LAE102, our internally discovered monoclonal antibody against ActRIIA, as a promising drug candidate for achieving muscle preserving weight control. In addition to LAE102, LAE103 is an ActRIIB-selective antibody, LAE123 is an ActRIIA/IIB dual antagonistic monoclonal antibody. Laekna has established a comprehensive ActRII portfolio and is actively advancing these drug candidates to clinical studies as novel therapies for muscle and other disease indications. The pre-clinical study results of our ActRII portfolio were presented at the 85th scientific sessions of ADA. The findings indicate that ActRIIA is a major regulator of muscle growth and fat loss. The company is in discussions with potential partners for strategic cooperations to accelerate development and commercialization of the ActRII portfolio. LAE102(ActRIIA monoclonal antibody) in Obesity, Phase I, China and U.S. By the end of December 2024, Laekna successfully completed the single ascending dose part of the Phase I clinical study (SAD Study) of LAE102 in China for the treatment of obesity. The first-in-human study results presented at the 85th scientific sessions of the ADA in June 2025 demonstrated that LAE102 has a favorable safety profile as well as robust and prolonged target engagement in both IV and SC injection groups. The first subject of the Phase I multiple ascending dose study (MAD Study) of LAE102 in China was enrolled and dosed at the end of March 2025. In November 2024, Laekna entered into a clinical collaboration agreement with Eli Lilly and Company. Lilly would be responsible for the execution and funding of a Phase I study in the U.S. Laekna retains global rights for LAE102. The first subject of the Phase I trial in the U.S was dosed in May 2025. LAE103 (an ActRIIB-selective antibody) Laekna obtained IND approval for LAE103 from FDA in July 2025. We target to initiate phase I clinical studies of LAE103 in the second half of 2025. LAE123 (an ActRIIA/IIB dual antagonistic monoclonal antibody) LAE123 is currently at IND-enabling stage. We target to advance it to phase I clinical studies in 2026.

作者：Medicina本文分享，2025年美国糖尿病协会（ADA）第85届科学年会上，诺和诺德与礼来，披露的一些管线进展和产品开发策略。AMYR vs. GLP-1R  从诺和诺德公司针对肥胖市场的产品组合策略中可以看出，减重深度排序为：Amylin类似物Cagrilintide＜GLP-1R激动剂Semaglutide＜Amylin类似物+GLP-1R激动剂CagriSema、AMYR/GLP-1R激动剂Amycretin＜三重激动剂，而安全性的排序与疗效相反。诺和诺德旨在通过针对不同患者特征、治疗目标以及安全性和耐受性来满足市场需求。  诺和诺德的追赶 诺和诺德公司在肥胖治疗领域的产品线正在不断扩展，其中Semaglutide已经成功上市。目前处于III期的产品为CagriSema（Amylin类似物+GLP-1R激动剂）、Amylin类似物Cagrilintide，以及GLP-1R/amylin receptor 激动剂Amycretin，可以看出诺和诺德的迭代产品选择了重点布局Amylin赛道。值得一提的是，今年3月份，诺和诺德从Lexicon Pharmaceuticals引进了临床前ACSL5抑制剂项目，以拓展减肥管线。诺和诺德（Novo Nordisk）公司由于礼来公司（Eli Lilly）在肥胖治疗领域的强势竞争，导致其市场份额被侵占，处于追赶状态。礼来的Tirzepatide（GLP-1R/GIPR激动剂，商品名为Mounjaro和Zepbound）在市场上表现出色，而诺和诺德一直未能推出能够超越该产品的资产，这在其三期临床资产Cagrisema（cagrilintide+semaglutide；amylin类似物+GLP-1R激动剂）的表现得到了体现。在糖尿病协会（ADA）会议上，诺和诺德公司分享了关于其两项关键资产的更多细节，这两项资产旨在帮助其在肥胖治疗领域重新站稳脚跟，分别是Cagrisema（cagrilintide+semaglutide）和amycretin（GLP-1R/AMYR激动剂），它们都是GLP-1/amylin receptor 激动剂。公司分享了来自Cagrisema的REDEFINE-1试验的进一步结果，分析师们认为该结果达到了礼来Tirzepatide所设定的标准，但并未击败其竞争对手。对于诺和诺德公司的另一个“关键产品”——Amycretin（GLP-1R/AMYR激动剂），分析师们希望找到证据来验证该公司将该资产推进至三期临床试验的决定，并进一步明确其与Tirzepatide的竞争优势。然而，Amycretin一期临床试验中采用的快速滴定方案让分析师们感到困惑，多位经纪人表示，该候选药物的安全性和有效性难以解读——这可能会将对其疗效特征的清晰理解推迟到2028年，届时公司预计将公布三期临床数据。诺和诺德公司在Amylin（胰淀素）领域进行了重点布局，胰淀素是一种多功能的激素，它在人体内具有多种作用，包括：①血糖调节，胰淀素能够增加对瘦素的响应性并减少胰高血糖素的分泌。②食欲调节，它可以减少食欲和能量摄入，同时增加饱腹感。③骨骼调节，胰淀素有助于抑制吸收和促进骨骼形成。④胃肠道作用，它能够减少胃酸分泌和胃排空。胰淀素类似物根据不同的分子骨架和受体选择性展现出不同的特性。诺和诺德的Amylin研发管线包括多个分子，它们处于不同的临床试验阶段：①Cagrilintide：Amylin类似物，已经进入III期临床试验。②Amycretin：GLP-1R/AMYR激动剂，即将开始III期临床试验。③Triple：这是一种三重激动剂，目前处于I期临床试验。④Amylin 355：也处于I期临床试验。⑥Amylin 1213：同样处于I期临床试验。  礼来领跑新赛道礼来在基于肠促胰素的疗法并非一夜成功，从2005年上市的GLP-1R激动剂Byetta（艾塞那肽），到2014年获批上市的度拉糖肽（GLP-1-Fc融合蛋白）。2017年，GIPR/GLP-1R激动剂tirzepatide的首次人体数据显示出减重效果，2022年获批上市治疗T2D，并于2023年获批上市治疗肥胖，2024年获批治疗阻塞性睡眠呼吸暂停。与诺和诺德的下一代产品重点布局在Amylin不同，礼来的肥胖迭代产品分为三个创新主题：①在肠促胰素方面，开发口服和长效多功能肠促胰素，围绕GIPR、GCGR与GLP-1R进行单独或组合开发。②Amylin管线，布局了一个产品，具不同选择性特征的Eloralintide（AMYR激动剂）。③新靶点方面，包括Bimagrumab（抗ACVR2B/ACVR2A单抗）和Nisotriosamide（PYY类似物），以增加肌肉等方面的New benefits。虽然诺和诺德公司正在努力跟上替西帕肽（Tirzepatide）的步伐，但礼来公司一直处于攻势，为下一代肥胖产品造势，其中以口服小分子GLP-1激动剂orforglipron为主导。在ADA会议上，公司分享了orforglipron的ACHIEVE-1试验的详细结果，没有看到严重的肝脏毒性。此外，礼来公司旨在通过口服候选药物的便利性来抢占诺和诺德Semaglutide的市场份额——尽管如果其疗效过于显著，它也可能开始侵蚀其自身的Tirzepatide业务。礼来公司还分享了针对活化素受体阻断抗体bimagrumab（anti-ACVR2B/ACVR2A单抗）和胰淀素激动剂eloralintide（AMYR激动剂）的早期阶段数据，这两者都可能在肥胖市场中服务于相对较小的人群。在ADA会议上展示的这两种药物的结果都可能是 Best-in-class。将bimagrumab添加到司美格鲁肽中同时增加了减重和瘦体重的保持，研究结果表明，bimagrumab和司美格鲁肽联合疗法相比单独使用任一疗法，能更显著地减少体重、体脂、内脏脂肪和炎症标志物。联合疗法中，脂肪质量占总减重量的92.9%，而单独使用司美格鲁肽时这一比例为71.5%；单独使用司美格鲁肽时下降了15.7%。值得注意的是，单独使用bimagrumab时，100%的减重量都归因于脂肪质量，并且总瘦体重增加了2.5%。而Eloralintide（AMYR激动剂）则产生了迄今为止胰淀素单一疗法中最快的减重效果。然而，礼来公司到目前为止强调了每个候选药物相对较窄的市场，将bimagrumab的使用案例描述为可能超重且已经缺乏肌肉量的老年患者，而其胰淀素激动剂为那些难以忍受肠促胰素胃肠道副作用的患者。小结  肥胖治疗领域正迎来新的发展阶段，其中产品创新的方向涵盖了给药途径、用药频率、额外代谢获益、耐受性、减重深度、减重质量以及血糖控制程度等多个方面。随着肥胖治疗市场逐渐细分，这些细分市场标准揭示了不同患者在选择治疗方案时的多样化需求和偏好。这不仅为制药公司提供了更精准的市场定位，也推动了企业开发更符合患者需求的治疗产品。欢迎大家加入BioPlus微信交流群，共同探讨。BioPlus微信交流群申请入群申请联系人 ：Lisa邮箱：lisa.li@bp-bioplus.com电话：18662346610（同微信）入群申请，请先添加Lisa微信，并分享名片入群画像 ：Biotech/药厂研发/BD、投资机构、临床医生等入群福利：不定时行业资料包分享参考文献：https://firstwordpharma.com/story/5976218https://investor.lilly.com/static-files/36604492-7d65-4649-bc20-f7b4372c2b2bhttps://www.novonordisk.com/content/dam/nncorp/global/en/investors/pdfs/ada/novo-nordisk-r-and-d-investor-event.pdf  拓展阅读  BioPlus-海外寻找资产系列：1.AACR复盘：9家CDH17-ADC数据对比2.自免小众靶点APRIL，正在悄悄火起来了！BioPlus国际大会跟踪系列：1. 2025 ASCO：ADC、双抗/多抗，有哪些看点？（附一览表）2. 2025 AACR 双抗与ADC有哪些看点？3. 小细胞肺癌领域，下一步将如何“破局”，ADC or TCE？4. ELCC 讨论：NSCLC的ADCs最新进展5. 未来ADC发展方向：新靶点，新载荷，双靶点/双表位...6. 2025 ASCO 重点项目临床数据：有哪些精彩看点？7. 2025 ASCO 重点项目临床数据（二）BioPlus靶点/管线研究系列：1. “待爆”：CDH17 ADC项目大比拼，谁将脱颖而出?2. PD-1激动剂在自免疾病项目数据盘点：失败项目的“坑”与启示3. 上临床就能卖？DLL3 ADC这么好卖？4. 胰腺癌三大热门靶点：CLDN18.2、EGFR、RAS5. TSLP/SCF双抗，下一个自免待爆靶点组合？6. GPC3靶点临床屡败，TCE能改写格局么？7. 亮相AACR，曾被临床终止的ADC靶点Ly6E，能否卷土重来？8. 最高18.45亿美元！赛诺菲为何重金买了两款TL1A双抗？9. 2025 Q1：BMS、Sanofi和Roche管线调整，哪些项目被砍？10. 现场！2025AACR：KRAS抑制剂的百花齐放11. IL-17小分子抑制剂，能否杀出重围？12.全球首款：华东医药申报MUC17 ADC药物13.荨麻疹 first-in-class双抗提交临床试验申请BioPlus技术平台深入剖析系列：1. TCE 免疫共刺激信号之选：CD2，一颗冉冉升起的新星2. BD爆发前夜！6家TCE Probody技术平台深度盘点3. TCE Probody：Amgen携重磅技术“破局“，改写行业格局？4. 有人放弃，有人前行！自免TCE全球管线大盘点5. Immunocore将TCR疗法照进现实，向自免疾病迈进6. B细胞清除免疫重置：SLE等疾病长效缓解终成现实！7. 国内50家CD3平台序列来源汇总8. CD28共刺激最终章？ZW209 DLL3/CD3/CD28 三抗剑指 Amgen9. TCE 结构之争落幕：行业用行动给出 “标准答案”10. CD3 VHH猴交叉：重要吗？11.Genentech创新前沿：口服VHH抗体，靶向IL-23R12.AbbVie专利公开：靶向PSMA/STEAP1 双抗ADCBioPlus人物专访：1. 专访肖亮：卖青苗不一定是坏事，这是中国Biotech长成参天大树的必经之路2. 专访王刚，恺佧生物这些年的“出海”之旅？
