S2E10 Sam Blackman: The Quest to Develop Medicines for Children with Brain Cancer

In this episode of Let’s Talk About That, Anirvan Ghosh speaks with Sam Blackman—pediatric neuro-oncologist, biotech founder, and storyteller—about the patients who shaped his life’s work and his search for a cure for children with brain cancer.As a physician caring for children with brain tumors, Sam witnessed firsthand the limits of existing treatments—and the urgency felt by families facing devastating diagnoses. That experience became a driving force behind his decision to help build a different kind of biotech company: one focused not on adapting adult drugs for children, but on developing therapies specifically for them.That vision led to the creation of Day One Biopharmaceuticals and ultimately to the development of tovorafenib, a targeted therapy approved in 2024 for children with low-grade glioma, the most common form of pediatric brain cancer.This is a conversation about compassion as a catalyst for innovation—and how one doctor’s commitment to his patients helped turn unmet need into a new medicine.
