In this episode, ARK’s Cathie Wood and Brett Winton sit down with Sean McClain, Founder and CEO of AbSci, to explore how generative AI is reshaping drug discovery, development timelines, and clinical costs. Sean walks through real-world examples of AI-designed antibodies—such as AbSci’s breakthrough HIV antibody and a regenerative treatment for hair loss—and explains how these platforms are helping unlock previously “undruggable” biology.
They discuss AbSci’s Phase 2-ready hair growth antibody (BS201), the company’s partnerships with Caltech and AMD, and why the FDA’s evolving embrace of AI could accelerate the end of animal testing. The conversation closes with a forward-looking discussion on the role of regenerative medicine in longevity—and why AI drug discovery might just pull biotech out of its multi-year bear market.
