从PD-1跟随到多款ADC领先,乐普生物-B(02157)迎价值重估?
智通财经网· 2025-05-09 04:30
Core Viewpoint - Lepu Biopharma-B (02157) has regained market attention due to significant progress in its ADC pipeline, leading to a stock price increase of nearly 78% year-to-date, despite a previous decline since its IPO in 2022 [1][18]. Group 1: Company Overview - Lepu Biopharma was established in 2018 and has built its pipeline through acquisitions and partnerships, including PD-1 antibodies and ADC drugs [1]. - The company focuses on integrating PD-1 as a cornerstone for cancer treatment while developing ADCs and other therapies for enhanced clinical outcomes [1][12]. Group 2: Financial Performance - In 2024, Lepu Biopharma is projected to achieve revenue of 368 million RMB, a year-on-year increase of 63.21%, driven by the commercialization of PD-1 [4]. - Despite revenue growth, the company reported a loss of 424 million RMB in the same year, with cash reserves remaining stable at 401 million RMB [4]. Group 3: Pipeline Development - The core drug in Lepu's pipeline is MRG003, an EGFR-targeting ADC, which has shown promising results in clinical trials for nasopharyngeal carcinoma (NPC) and head and neck squamous cell carcinoma (HNSCC) [4][10]. - MRG003 has received breakthrough therapy designation from both the CDE and FDA, indicating its potential in treating difficult-to-manage cancers [10]. Group 4: Competitive Landscape - The global market for EGFR-targeting ADCs is competitive, with several companies, including Rakuten Medical and Systimmune, also developing similar therapies [6][7]. - Lepu's MRG003 has demonstrated superior efficacy compared to existing treatments, with an overall response rate (ORR) of 47.4% in NPC patients, significantly higher than the typical 20-30% ORR for second-line therapies [7][10]. Group 5: Future Prospects - The company is actively exploring combination therapies, such as MRG003 with PD-1, which has shown an ORR of 66.7% in early trials [12]. - Lepu is also advancing its CG0070 oncolytic virus therapy, which has shown promising results in treating non-muscle invasive bladder cancer (NMIBC) and has received breakthrough therapy designation from the FDA [14][15]. Group 6: Challenges Ahead - Despite the positive developments, Lepu Biopharma's reliance on external acquisitions for its pipeline raises questions about its internal R&D capabilities [18]. - The company faces challenges related to ongoing losses and the need for substantial funding to support its numerous clinical trials [18].
牛磺酸龙头实控人遭留置,“金融少帅”能否打破永安药业转型困局?
2 1 Shi Ji Jing Ji Bao Dao· 2025-05-08 10:09
这场代际交替中的转型突围战,既考验着接班人的战略定力,也决定着这家行业龙头能否穿越周期。 突遭留置引发连锁反应 5月5日的一纸公告,将永安药业推向了风口浪尖。公司实际控制人、董事长陈勇被立案调查并实施留 置。这一突发事件不仅引发了永安药业次日股价的"一字"跌停,也使其未来发展充满了不确定性。 对于实控人涉案的影响,公司5月8日的回应仍显模糊。永安药业表示:"目前,公司尚未知悉上述事项 的进展和结论,也无法了解需要多久,公司将持续关注上述事项的进展情况,并严格按照相关规定及时 履行信息披露义务。" 紧急接棒的"85后"少帅陈子笛面临双重考验。这位金融背景出身的接班人不仅要稳住陈勇被查带来的治 理危机,还需应对牛磺酸行业的变局。尽管永安药业手握全球牛磺酸50%市场份额,但原料价格波动以 及市场产能增多,正在侵蚀其传统成本优势。 21世纪经济报道记者 李佳英 广州报道 与此同时,永安药业转型之路同样步履维艰。虽然永安药业加码肌酸、保健品等新业务,但2024年相关 板块收入均同比下滑超20%,远未形成接力牛磺酸的第二增长曲线。 一纸公告将永安药业推入风暴中心。近日,永安药业实际控制人、董事长陈勇突遭立案调查并实施留 ...
2850万年薪CEO砍74%研发费控成本!基石药业公布CS2009产品新成果亟待破局
Sou Hu Cai Jing· 2025-05-07 05:40
公司对于成本的控制,也体现在高管团队的报酬方面,多数高管薪酬变化不大,变化降低的只有CEO兼研发总裁的杨建新,虽然其 报酬比2023年下降超过50%,仍有逾2850万元,可谓"一枝独秀",而其他高管成员无人达到百万级别。 5月6日,基石药业(苏州)有限公司(2616.HK,以下简称"基石药业")通过官网披露,公司在2025年美国癌症研究协会 (AACR)年会上公布了产品CS2009的临床研究成果。 内容显示,这款整合PD-1、VEGFA、CTLA-4三大靶点的全球首创药物,在对靶点的亲和力、检查点活性、非毒性、耐受性等方面 均有不错表现。目前该产品的全球多中心I期临床研究正在澳大利亚进行,已于今年3月完成首例患者给药,预计后续将扩展至中国 和美国。 图片来源:美国癌症研究协会官网 然而在这项进展背后,公司的2024年年报却透露出一系列值得玩味的财务信号:营业收入4.07亿元,连续两年下滑;归母净利 润-0.91亿元,上市以来6年全负;资产负债率升至新高73.89%,经营性现金流净流出3.43亿元,CEO杨建新报酬减半仍有2850.10万 元(港币金额3021.39万)。在研发突破与财务压力的双重夹击下,这家创 ...
Cell子刊:复旦大学骆菲菲/储以微团队开发新型CAR-T细胞疗法,提高对实体瘤的治疗效果
生物世界· 2025-05-06 07:45
撰文丨王聪 编辑丨王多鱼 排版丨水成文 CAR-T 细胞疗法 在血液系统癌症中取得了令人瞩目的治疗效果,然而,其在占据癌症绝大多数的实体瘤中效果差强人意,且反应通常难以持久。 实体瘤的 肿瘤微环境 (TME) 以低氧和营养匮乏为特征,并且持续存在的 肿瘤抗原刺激,会损害 CAR-T 细胞的代谢,导致其耗竭和功能障碍。这也被认为是 CAR-T 细胞疗法在实体瘤治疗中面临的主要瓶颈之一。值得注意的是,在这种肿瘤微环境中, Foxp3 能够赋予 调节性 T 细胞 (Treg) 代谢方面的优势。 2025 年 5 月 5 日, 复旦大学附属华山医院 骆菲菲 研究员团队联合复旦大学生物医学研究院/基础医学院 储以微 教授团队 ( 复旦大学基础医学院 牛聪义 为论 文第一作者) 在 Cell 子刊 Cell Metabolism 上发表了题为: Foxp3 confers long-term efficacy of chimeric antigen receptor-T cells via metabolic reprogramming 的研究论文。 该研究首次揭示了 Foxp3 通过非转录依赖的线粒体动态调控机制,重塑 ...
