Atavistik Bio is a Cambridge, Massachusetts clinical-stage biotechnology company that discovers precision allosteric small-molecule medicines. Its proprietary AMPS (Atavistik Metabolite-Protein Screening) platform, paired with an AI-enabled discovery engine, uses natural metabolites as bait to reveal hidden allosteric pockets on disease-driving proteins that conventional drug discovery cannot reach. The company is advancing an oral AKT1-selective inhibitor for hereditary hemorrhagic telangiectasia (HHT) and a JAK2 V617F mutant-selective program for myeloproliferative neoplasms (MPNs).
Ensem Therapeutics is a Waltham, Massachusetts clinical-stage biotech using its Kinetic Ensemble platform - a blend of AI/ML, molecular simulation, and experimental biophysics - to find cryptic and allosteric pockets in proteins that are otherwise considered difficult to drug. The company designs small-molecule precision medicines for cancer, with two lead programs: ETX-636, an allosteric pan-mutant-selective PI3Kalpha inhibitor and degrader for breast cancer (FDA Fast Track), and ETX-197/BG-68501, a selective CDK2 inhibitor partnered with BeiGene.
Brenig Therapeutics is a neurology-focused biotechnology company building disease-modifying small-molecule therapies for Parkinson's disease and other neurodegenerative disorders. Founded in 2021 and backed by $65 million in Series A funding led by NEA, Brenig pairs AI- and machine-learning-driven discovery with structure-based design to engineer brain-penetrant molecules that hit the central nervous system while sparing the rest of the body. Its lead candidate, BT-267, is a selective LRRK2 inhibitor now in human trials, followed by BT-409, a brain-selective NLRP3 inflammasome inhibitor targeting neuroinflammation.
