Alphabet’s AI-driven drug discovery firm, Isomorphic Labs, is poised to enter a critical new phase as it readies its first human clinical trials for cancer treatments designed entirely using artificial intelligence. This marks a potential breakthrough moment not only for the company, but for the broader pharmaceutical industry.
Founded in 2021 as a spinout from Google DeepMind, Isomorphic Labs is built on the foundation of AlphaFold—a revolutionary AI system that predicted the 3D structure of proteins with unprecedented accuracy. The current version, AlphaFold 3, extends this capability by modeling complex interactions between proteins, DNA, RNA, and drug molecules. This enables researchers to simulate and optimize drug candidates long before any laboratory testing begins, potentially accelerating timelines, reducing costs, and improving success rates in drug development.
In a recent interview with Fortune, Colin Murdoch, President of Isomorphic Labs, confirmed that the company is “very close” to initiating clinical trials. “There are people sitting in our office in King’s Cross, London, working and collaborating with AI to design drugs for cancer. That’s happening right now,” he said.
The company’s hybrid approach—merging cutting-edge AI with pharmaceutical expertise—is already attracting interest from major industry players. In 2024, Isomorphic signed multi-year research partnerships with global pharmaceutical leaders Novartis and Eli Lilly. Earlier this year, the company also secured $600 million in external funding, led by Thrive Capital, to advance its in-house drug candidates, with oncology and immunology among its initial focus areas.
While the prospects of AI-driven drug discovery are exciting, they also raise important ethical and regulatory considerations. The opaque, “black box” nature of many AI systems presents challenges in an industry where transparency, safety, and accountability are paramount. Questions around intellectual property, accessibility, and liability remain unresolved.
Despite these concerns, the potential impact is significant. If successful, Isomorphic Labs could pave the way for a more efficient, cost-effective, and targeted model of drug development—one that redefines how medicines are discovered and delivered. The journey ahead will depend not only on the power of AI, but also on the readiness of regulators, healthcare professionals, and society to embrace a new era in medicine.
