In this episode of The Biotech Startups Podcast, we follow Roy Maute’s journey from the Gilead acquisition of Forty Seven Inc. through COVID-era corporate life—where he spent over a year at Gilead without meeting colleagues in person—to co-founding Pheast Therapeutics in 2021, clarifying his passion for early-stage company building. He unpacks how he, Amira Barkal, Irving Weissman, and Ravi Majeti rallied around CD24 as the next macrophage checkpoint target, explains PHST001 and why macrophage checkpoint inhibitors could form a new class of immunotherapy, and reflects on building a lean, 34-person clinical-stage company, navigating a tougher post-COVID fundraising environment, and charting the road ahead as Pheast generates pivotal clinical data.
