Teon Therapeutics, Inc.

Teon Therapeutics is a clinical-stage, privately held biopharmaceutical company in Redwood City, California, developing a focused portfolio of orally administered small-molecule drugs that block immunosuppressive, cancer-promoting signaling pathways in the tumor microenvironment. Its GPCR-directed candidates - TT-702, a first-in-class adenosine A2B receptor antagonist, and TT-816, a first-in-class cannabinoid CB2 receptor antagonist - aim to restore anti-tumor immunity for the roughly 88% of solid-tumor patients who do not benefit from existing immunotherapies. The founding team members were primary inventors of Lexiscan, the only FDA-approved selective adenosine therapeutic.
