Load more (106 remaining) 关于 Altimmune, Inc. Altimmune, Inc. 是一家在美国纳斯达克(美国)上市的生物技术公司,专注于开发严重肝病的疗法。该公司是一家处于临床后期阶段的生物制药开发商,其战略目前以其主要候选药物 pemvidutide 为中心,该药物正在针对具有重大未满足医疗需求的代谢和肝脏相关适应症进行推进。Altimmune 的总部位于马里兰州盖瑟斯堡,使其成为美国东海岸关键生物制药中心之一。([ir.altimmune.com](https://ir.altimmune.com/news-releases/news-release-details/altimmune-announces-fourth-quarter-and-full-year-2025-financial))
从历史角度看,Altimmune 成立于 1997 年。公司目前的组织形式反映了重大的战略演变,包括在 2017 年完成与 PharmAthene 的合并,之后合并后的实体以 Altimmune, Inc. 的名义在纳斯达克上市,股票代码为 ALT。随着时间的推移,业务已从更广泛的疫苗/免疫治疗产品组合转向以 pemvidutide 和肝病机会为核心的更窄、更具信心的临床重点。([stockanalysis.com](https://stockanalysis.com/stocks/alt/company/?utm_source=openai))
在运营方面,Altimmune 目前高度专注于 pemvidutide 在 MASH(代谢功能障碍相关脂肪性肝炎)、酒精使用障碍 (AUD) 和酒精相关肝病 (ALD) 方面的开发。管理层披露,pemvidutide 已获得 FDA 突破性疗法认定,全球 PERFORMA 3 期 MASH 试验计划于 2026 年下半年启动,RECLAIM 2 期 AUD 研究的顶线数据预计将于 2026 年第三季度公布。RESTORE 2 期 ALD 试验也在推进中,使得该公司 2026 年的日程对于一家单一资产生物技术公司而言异常丰富,充满催化剂。([sec.gov](https://www.sec.gov/Archives/edgar/data/1326190/000132619026000037/alt-20260513xex99d1.htm))
在竞争方面,Altimmune 相对于大型制药公司和资本更雄厚的生物技术同行(目标是肝脏和代谢疾病)而言,仍然是一个相对较小的参与者。其投资案例取决于 pemvidutide 是否能展示出差异化的疗效/耐受性特征,以及该特征是否能转化为临床、监管并最终实现商业价值。公司本身强调了 pemvidutide 解决关键未满足需求的潜力,尤其是在 MASH 领域,已获批的疗法并未消除巨大的差异化空间。([ir.altimmune.com](https://ir.altimmune.com/news-releases/news-release-details/altimmune-announces-fourth-quarter-and-full-year-2025-financial))
近期发展对投资者而言非常重要。2026 年 4 月,Altimmune 完成了一次超额认购的公开发行,募集总收益 225 million 美元,明确用于资助 3 期 MASH 项目并延长现金流至预期的 52 周读数。在 2026 年第一季度更新中,公司报告截至 2026 年 4 月 30 日,现金、现金等价物和短期投资约为 535 million 美元。对于追踪 SEC Form 4 内部交易的投资者而言,这些融资和治理披露,以及内部人申报,使得 Altimmune 成为一家备受关注的小盘生物技术公司,具有重大的事件驱动潜力。([ir.altimmune.com](https://ir.altimmune.com/news-releases/news-release-details/altimmune-announces-closing-225-million-oversubscribed-public))
