Its flagship product, the SAGE Oncotest, grows hundreds of live 3D microtumors from a patient's own fresh tumor biopsy and tests them against a panel of FDA-approved chemotherapies and targeted drugs, predicting which treatments a tumor will resist or respond to within 7-10 days - independently of genetic mutations. The company reports actionable results in 88% of cases versus roughly 26% for genomic tests. Founded by physician-scientists Dr. Chris Apfel and Dr. Brigitte Apfel, SageMedic aims to more than double a patient's odds of receiving the most effective therapy the first time.
