AI药物开发启动Pathos AI关闭2.37M投资。
Pathos AI Inc. 今天的宣布公司以30亿美元估值，拥有融资2.37亿美元的资金。
制药巨头布里斯托尔·迈尔斯·斯基布(英语：Bristol Myers Squibb Co.)领导了E系列赛，有几位不知名的回归者参加。 Pathos的投资者名册包括大名，如AstraZeneca plc、NEA和General Atlantic。
Pathos正在利用一个名为Foundry的人工智能平台开发癌症药物。 据该公司称，该软件可访问约200个微字节的肿瘤数据。 它还吸收了Pathos药物开发方案所产生的信息。 Foundry分析这些数据集，以帮助公司的研究人员更有效地开展工作。
药物研究计划有时会产生数百个药物候选者，分子有可能转化为药物。 铸币局利用AI agents确定最有前途的分子。 从那里，它可以确定哪些病人可以从每次治疗中受益最大。
Pathos还使用Foundry来规划它开发的药物的临床试验。 称公司的试验是“生物标志驱动的”。 生物标记是生物现象，可以提供对药物有效性的洞察。 它们有多种形式，从蛋白质到血压等病人的度量。
称 Pathos公司首席执行官Iker Huerga, “基金会从根本上加快了我们确定很有前途的临床资产并将其纳入我们管道的能力。”
Pathos将利用其系列E回合资助其药物开发工作。 该公司说，其“关键优先事项”是其JSKN016方案，其目的是在所谓的抗体-药物共生治疗基础上发展癌症疗法。
抗体是识别致病细胞并与之结合的分子。 一旦一个抗体被附着在细胞上，它就起到引起免疫系统注意的善良信标的作用。 免疫细胞随后发现抗体，并摧毁其附着的细胞。
抗体-药物结合剂利用这种方法的变异治疗癌症。 他们被有效升级了抗体含有抗原，一种具有治疗性能的分子。 抗体-药物结合物附着在癌细胞上，使其吸收抗原，使其中和。
Pathos还将利用资本资助另外三个药物方案。 其中一项举措是与去年投资该公司的AstraZeneca公司合作。 该联合方案寻求开发一种所谓的ER PROTAC药物，利用细胞内置的材料回收机制治疗癌症。
布里斯托尔·迈尔斯·斯基布(英语：Bristol Myers Squibb)今天对Pathos 宣布的投资是公司之间更广泛的伙伴关系的一部分。 合作还涉及一个公开交易的医疗数据提供者Tempus AI公司。
Pathos将在5年中支付5,500万美元，以发放从神经疾病患者收集的匿名数据。 前公司将利用Foundry来分析这些信息，以更好地了解疾病生物学。 此外，还将向布里斯托尔·迈尔斯·斯基布提供Foundry和数据集。 制药者将利用这些药来改进其临床试验，并确定最有可能受益于新药的患者。

AI drug development startup Pathos AI closes $237M investment
Pathos AI Inc. today announced that it has raised $237 million in funding at a $3 billion valuation.
Pharmaceutical giant Bristol Myers Squibb Co. led the Series E round with participation from several unnamed returning backers. Pathos’ investor roster includes big names such as AstraZeneca plc, NEA and General Atlantic.
Pathos is developing cancer drugs using an artificial intelligence platform called Foundry. According to the company, the software has access to about 200 petabytes of oncological data. It also ingests the information generated by Pathos’ drug development programs. Foundry analyzes those datasets to help the company’s researchers pursue their work more efficiently.
Pharmaceutical research programs sometimes produce hundreds of drug candidates, molecules that can potentially be turned into medicines. Foundry uses AI agents to pinpoint the most promising molecules. From there, it identifies the patients who could benefit the most from each therapy.
Pathos also uses Foundry to plan clinical trials for the drugs that it develops. The company says that its trials are “biomarker-driven.” Biomarkers are biological phenomena that can provide insight into the effectiveness of a drug. They take a wide variety of forms ranging from proteins to patient metrics such as blood pressure.
“We are building a platform to systematically improve the probability of success in drug development,” said Pathos Chief Executive Officer Iker Huerga. “Foundry has fundamentally accelerated our ability to identify highly promising clinical assets and integrate them into our pipeline.”
Pathos will use its Series E round to finance its drug development efforts. The company stated that its “key priority” is its JSKN016 program, which aims to develop a cancer therapy based on a so-called antibody-drug conjugate.
Antibodies are molecules that identify disease-causing cells and bind to them. Once an antibody is attached to a cell, it functions as a kind beacon that draws the attention of the immune system. Immune cells subsequently find the antibody and destroy the cell to which it’s attached.
Antibody-drug conjugates use a variation of that approach to treat cancer. They’re effectively upgraded antibodies that contain an antigen, a molecule with therapeutic properties. Antibody-drug conjugates attach to cancer cells and cause them to absorb the antigen, which neutralizes them.
Pathos will also use the capital to finance three other drug programs. One of those initiatives is a collaboration with AstraZeneca, which invested in the company last year. The joint program seeks to develop a so-called ER PROTAC drug, which harnesses cells’ built-in material recycling mechanism to treat cancer.
The investment from Bristol Myers Squibb that Pathos announced today is part of a broader partnership between the companies. The collaboration also involves Tempus AI Inc., a publicly traded medical data provider .
Pathos will pay Tempus $55 million over five years to license anonymized data collected from patients with neurological conditions. The former company will analyze that information using Foundry to gain a better understanding of disease biology. Additionally, it will make both Foundry and the dataset available to Bristol Myers Squibb. The drugmaker will use them to improve its clinical trials and identify patients most likely to benefit from new drugs.
