About

Nexo Therapeutics is a small-molecule oncology company founded in 2022 that discovers drugs against cancer targets historically considered undruggable. It applies covalent ligand discovery across all nucleophilic amino acids, combined with chemical biology, cancer biology and medicinal chemistry, to reach proteins that lack well-defined binding pockets. The company is headquartered in Littleton, Colorado with research laboratories in Watertown, Massachusetts, and raised a $60 million Series A from Versant Ventures, Cormorant Asset Management and New Enterprise Associates alongside a research alliance with The University of Texas MD Anderson Cancer Center.

Covalent ligand discovery across all nucleophilic amino acids captures shallow, transient and otherwise intractable pockets, aiming at the roughly 80% of the proteome that conventional small-molecule drugs cannot reach.

Product

Covalent ligand discovery platform

Oncology drug discovery platform

A drug discovery engine that pairs covalent chemistry across all nucleophilic amino acid residues with chemical biology and cancer biology to generate small-molecule candidates against targets without conventional binding pockets, including intrinsically disordered proteins, scaffolding proteins, transcription factors, paralogs and protein-protein interfaces.

  • Covalent ligand discovery across all nucleophilic amino acids
  • Targets intrinsically disordered proteins, scaffolding proteins and transcription factors
  • Captures shallow, challenging and transient binding pockets

Built for

Cancer patients who lack meaningful therapies, reached via pharmaceutical partners and, ultimately, oncologists prescribing approved medicines
