409: Predicting biotech clinical trials & a new Alzheimer's drug controversy

On this week’s episode of "The Readout LOUD": The Kalshi prediction markets are coming for biotech, plus the controversy over an experimental Alzheimer’s disease treatment from Biogen. Kalshi, the maker of prediction markets, announced this week that it is expanding into biotech. Soon, you’ll be able to make bets on the outcomes of clinical trials and FDA drug reviews. Is that a good thing? We’ll discuss the issues with Jonathan Kimmelman, a bioethicist at McGill University who has researched prediction in clinical trials. We also chat about Biogen and its tau-lowering drug for Alzheimer’s. A mid-stage clinical trial presented this week showed the drug reduced levels of the tau protein and slowed the rate of cognitive decline in patients. But the data also raised a lot of questions that left experts and investors debating the drug’s future.
