🧬 Multi-Edit CAR T-Cells: The Crazy Science That Might Cure Brain Cancer | Aaron Edwards (Part 4/4)
July 30, 2025
“This isn't just one gene edit—this is multiple edits, working in concert. It’s a fundamentally different chassis.” In this episode of The Biotech Startups Podcast, Aaron Edwards, co-founder of KiraGen Bio, shares how a Harvard Business School class project ignited the launch of a pioneering biotech taking on solid tumors with a bold, unconventional CAR T-cell therapy. He unpacks the real-world challenges of building KiraGen—navigating fundraising, assembling a strong team, and leveraging mentorship, partnerships, and machine learning—while highlighting how focus, discipline, and authentic leadership can set a startup apart, even when it means breaking from industry norms.
