Relay Therapeutics

AI Drug Discovery

Cambridge MA precision oncology biotech using Dynamo platform to exploit protein motion for drug design; lead asset RLY-2608 targets PI3Kα in breast cancer.

About

Relay Therapeutics was founded in 2016 in Cambridge, Massachusetts, emerging from research at MIT and D.E. Shaw Research. The company is built around its Dynamo platform, which integrates computational protein motion modeling (molecular dynamics simulations) with structural biology and medicinal chemistry to design small-molecule drugs that exploit the dynamic conformational states of disease-relevant proteins—a dimension traditional structure-based drug design ignores.\n\nRelay's lead program, RLY-2608, is a first-in-class allosteric, mutant-selective PI3Kα inhibitor for advanced breast cancer patients with PI3KCA mutations. Unlike approved PI3Kα inhibitors that cause metabolic toxicity by inhibiting wild-type PI3Kα in normal tissues, RLY-2608 selectively targets the mutant form. The compound has shown early clinical promise including objective responses in patients who progressed on prior alpelisib, supporting a differentiated profile. Additional programs target FGFR2 and SHP2 in solid tumors.\n\nRelay has raised over $1.2 billion in equity financing and holds substantial cash reserves. The company is conducting multiple clinical trials and building a pipeline that validates its Dynamo-guided discovery approach. Though revenue-stage remains early, Relay represents a leading example of next-generation computational oncology companies seeking to turn protein dynamics insights into selective, differentiated medicines.

AI Drug Creation

Absci is an AI drug creation company that combines generative AI with a synthetic biology platform to design novel therapeutic proteins from the ground up.

About

Absci is a publicly traded AI drug creation company founded in 2011 that went public in 2021 and has repositioned around generative AI for drug design. The company operates an integrated platform that uses generative AI to design novel antibodies and proteins, then validates them using high-throughput expression and biological assay systems in its own wet lab infrastructure. Absci's approach treats drug discovery as a generative design problem, using AI to propose protein sequences with desired therapeutic properties and then rapidly testing millions of candidates to identify viable drug leads. The company has established drug creation partnerships with major pharmaceutical companies including AstraZeneca, Merck, and EQT Life Sciences. Absci's technical differentiation lies in its ability to close the loop between AI-generated protein designs and experimental validation at unprecedented scale. The company represents a new category of AI-native biopharmaceutical company that combines computational and wet-lab capabilities to create drugs not discoverable through traditional means.
