Welcome to IDEA Collider. In this episode, host Alex Gray is joined by IDEA Pharma colleagues David Radwaner and Tom Brockbank to dissect the history, strategy, and future of immuno-oncology (IO). The trio explores how PD-1 and PD-L1 therapies revolutionized cancer treatment, acting as a brake on the immune system to offer unprecedented durability and long-term survival for patients.
They take a deep dive into the fascinating commercial and clinical race between Merck's Keytruda and BMS's Opdivo. Learn how Merck's strategic decisions—including smart statistical trial designs, targeted biomarker approaches in first-line non-small cell lung cancer, and tumor-agnostic labels like MSI-high—allowed Keytruda to secure market dominance. Finally, Alex, David, and Tom look ahead to the next ten years, discussing whether emerging players like AstraZeneca and China's Akeso / Summit will displace Keytruda, or if the future lies in combination therapies.
