Novel AI-based discoveries of biomarkers and new drug options for significantly life-prolonging outcomes

Our Cutting-Edge Technology
Cancer Treatment Optimization Solutions (CATOS)

Sostos LLC is a provider of cutting-edge artificial intelligence (AI)/big data technologies and health analytics services for precision medicine. CATOS products enable personalized cancer care throughout the patient journey from cancer screening, liquid biopsies, diagnosis, prognosis, treatment selection, to new drug options for patients with failed prior therapy. Our AI technology/software is proven effective in satellite system reliability assurance and precision oncology. Using our AI technology, our developed 7-gene lung cancer assay (CATOS-LU) for prognosis and prediction of therapeutic benefits has been validated in more than 1,600 patients including randomized phase III clinical trials. Using our AI/big data software, we have identified 16 therapeutic compounds as new or repositioning drugs for improving cancer patient survival outcomes. CATOS software can effectively improve cancer theranostics by efficiently analyzing multi-omics profiles of patient single cells, liquid biopsies, biopsies, and bulk tumors. Our technologies have been funded by the NSF, NASA, NIH, CDC, and CPSC.
