嘉宾/话题简介

Alex Carnault 是 Braidwell 的创始人兼管理合伙人,被誉为顶尖的生物医疗投资人。他的职业生涯始于 美林(Merrill Lynch) 的衍生品交易台,后加入 Deerfield Management 并共同领导该基金长达 15年,专注于生命科学领域的投资与建设。本集对话中,他基于二十年的行业亲身实践,从 GLP-1 浪潮出发,系统阐述了一套针对衰老疾病的“预防型健康栈”,并深入探讨了 PCSK9、阿尔茨海默症、癌症早筛、AI 制药以及个人健康主动性等关键命题,最终落脚于一场旨在节省万亿美元医疗开支的公共健康革命。

“这些药物让我们看到,当我们触及疾病的根源时会发生什么……我认为我们现在可以得出结论,这是一类年收入将轻松突破 1000 亿美元的药物。”

"These medicines are showing us what happens when we get to the root of disease... I think it's easy now to conclude that this is a class of medicines will easily be in excess of $100 billion a year in revenue."

“大多数中年人都有 30% 到 50% 的几率在 40 岁到 80 岁之间发生心脏病或中风,而这在我看来是悲剧,因为我们有药物能把这个风险大幅降低到 10% 左右。”

"Most middle-aged men and women walking around have somewhere between a 30 and a 50% probability of having a heart attack and a stroke... we have the medicines that exist that can help us to dramatically lower that risk to some 10%."

💬 精华片段(中文)

“就在几个月前,GLP-1 市场每周还只有大约 20 万个新处方,我上周五看到的最新数据是,这个数字已经从每周 20 万上升到了 30 万,仅仅几个月时间。太疯狂了。”

"...the GLP-1 market was moving at about a 200,000 recorded new scripts per week... The most recent data that I looked at this past Friday says that that is now moved from 200,000 a week to 300,000 a week in just a few months time. Crazy."

💬 精华片段(中文)

“当你审视为了最大限度延长寿命、提升生命质量而必需的五道防线时,我从根本上认为,没有任何分子能比 GLP-1 在这整个轴向上更重要。”

"When you look across the five axes, the five layers of defense that are mission critical for us maximizing the number of years we can live and having the most life in those years, I fundamentally believe there's no molecule that's more important than GLP-1 across that entire axis."

💬 精华片段(中文)

“诺和诺德过去一年给出的很有说服力的数据表明,服用 GLP-1 药物带来的超过 20% 的心脏病或中风风险降低,是独立于体重减轻的。”

本节重点

详细精要

💬 精华片段(中文)

“我可以在手机上打开亚马逊,点个按钮第二天就能拿到牙膏。但为了保护自己不得心脏病,却要经历几百通电话、多次看病、反复被扎针,这简直毫无道理。”

"I can go on my iPhone, I can go to Amazon, I click a button and the next day I can get toothpaste. But it takes me an incredible journey, hundreds of phone calls, multiple doctor visits, being pricked and prodded multiple times just to protect myself from having heart attack. Like that doesn't make sense."


[35:37] PCSK9 抑制剂:来自人类遗传学的“免费午餐”

本节重点

💬 精华片段(中文)

“从人类基因观察和纵向数据中,我们发现基因缺失导致 PCSK9 不产生的人群,其终身心血管疾病的发病风险降低了 88%。这简直是奇迹。”

"The fact that they were genetically deficient in the production of the PCSK9 protein led to them having an 88% reduction in the risk of ever developing cardiovascular disease. That was miraculous."


[45:30] 阿尔茨海默症:走出荒地,迎来早期干预曙光

本节重点

详细精要

💬 精华片段(中文)

“如果我们能尽早把人筛选出来并尽快让他们用药,不仅能在损伤发生前就在那里,还能提前堵住造斑块的水龙头。这样一来,我们完全有可能在一个没有这种疾病的世界里醒来。”

"If we can start giving people these medicines as early as possible... you can think about it as turning off the faucet. We might be able to wake up in a world where we live without this disease."


[49:59] 癌症:早检革命与动态精准治疗

本节重点

详细精要

💬 精华片段(中文)

“癌症很难对付,部分原因是我们总是发现得太晚,而且即便发现了,癌症就像一个狡猾的魔鬼,一旦你用一种药物把它克制住,它就立刻改变逃逸路径。”

"Cancer is hard, both because we often identify it too late. And then when we do, cancer is like a sneaky devil... as soon as you're making progress with a medicine against that angle of attack, all of a sudden the cancer has a survival instinct and it redirects."


[59:39] 药物发现:科学方法、资本与 AI 超级驱动

本节重点

详细精要

💬 精华片段(中文)

“我开始反思,我在教我女儿什么?我花了这么多时间、热情和资本推动创新,但如果病人平均只吃一年药就停了,那我们到底在做什么?只是在优化最大收益,而不产生任何公共健康影响吗?”

"I started thinking about well for what purpose if people need to be on a medicine for the rest of their lives and they're taking it for a year on average and then quitting. Are we just optimizing for maximum expected returns but no impact on public health."


[01:33:42] Braidwell 的投资哲学与晨会

本节重点

详细精要

💬 精华片段(中文)

“为了成为一个伟大的创新支持者,我们必须系统性地回答三个问题:这些创新是成功还是会失败?它们最终在市场上是举足轻重还是无足轻重?有没有一种支持它的方式,能产生足够的回报,对得起那些把资金托付给我们的投资者?”

"We essentially need to be able to answer three questions are the innovations we're getting behind going to work or fail are they ultimately going to be relevant from a market potential or not. And is there a way by which we could back this company invest in this company... with capital that produces a return that's attractive enough for the investors that are trusting us with their capital."


专业术语注释

术语 解释
GLP-1(胰高血糖素样肽-1) 一种人体小肠自然分泌的激素,主要作用是增强胰岛素分泌、延缓胃排空并向大脑发送饱腹信号。药物利用其长效类似物来治疗糖尿病、减肥及预防心血管疾病。
PCSK9 抑制剂 一类通过抑制 PCSK9 蛋白,从而增强肝脏清除血液中低密度脂蛋白(LDL)能力的药物。由于有天然遗传缺陷证明无害甚至有益,被视为近乎无副作用的降胆固醇“免费午餐”。
LDL(低密度脂蛋白) 常被称为“坏胆固醇”,会在血管壁逐渐堆积形成动脉粥样硬化斑块,是导致心脏病发作和中风的主要元凶。
抗淀粉样蛋白药(Anti-amyloid) 针对阿尔茨海默症开发的单克隆抗体,能直接与脑内堆积的β-淀粉样蛋白斑块结合并帮助免疫系统清除它们。
MCED(多癌种早期检测) 通过一次液体活检(如抽血)同时筛查多种器官早期癌症及其组织起源的检测技术。
CAR-T 疗法 嵌合抗原受体T细胞疗法,通过基因改造从患者或体内直接提取的免疫细胞,使其能精准识别并攻击癌细胞。
RNA 干扰(RNAi) 一种利用小干扰RNA分子特异性沉默致病基因表达的疗法,在本集中用于从肝脏源头切断 PCSK9 蛋白的生成。
敏感性 / 特异性 肿瘤早检评价指标。敏感性指检出全部实际患癌者的比例;特异性指排除全部未患癌者的比例,决定了多少假阳性会给健康人带来困扰。
In Silico 拉丁语“在硅上”,指利用计算机模拟而非物理湿实验来预测分子活性或进行药物筛选。
BMI(身体质量指数) 衡量肥胖程度的标准,按数值可分为正常、超重(25-30)、肥胖(30-40)及病态肥胖(40+)。
食物噪音(Food Noise) 指持续不断、难以控制的关于进食的念头或欲望,GLP-1 类药物可通过中枢作用显著降低这种杂音。
