Antares Therapeutics

Antares Therapeutics is a Boston-based biotechnology company that discovers small-molecule precision medicines against historically 'undruggable' targets in cancer and other serious diseases. Spun out of Scorpion Therapeutics in June 2025 with $177 million in Series A financing, Antares combines proprietary compound libraries, next-generation mass spectrometry, chemical proteomics, and machine-learning-driven computational chemistry to find new binding pockets on proteins - such as transcription factors - that were long considered impossible to drug. Its lead program is slated to enter the clinic in 2026, and the company signed a collaboration worth up to $1.9 billion with Novartis in mid-2026.
