Circadian OS

Circadian OS is a circadian therapeutics company pioneering a new class of medicine that measures and reprograms the body's internal biological clock to improve cancer treatment outcomes. The company combines a blood test to assess a patient's circadian clock gene phase with a personalized light therapy regimen, delivered via an iPad app, to strengthen and stabilize the circadian system, driving patients toward higher peaks of immune responsiveness. By making clock gene phase and amplitude controllable variables, Circadian OS aims to amplify the efficacy of cancer immunotherapy. Founded by Sofia Axelrod, a former scientist in a Nobel Prize-winning laboratory, the company is backed by SOSV and is advancing a clinical trial portfolio grounded in Nobel-pedigree circadian science.
