Tools/Drug Development Support Tech
Sostos has developed a unique software technology that can
identify personalized cancer treatment solutions for patients. Our
Artificial Intelligence (AI) system is called CATOS - Cancer
Treatment Optimization Solution. CATOS can scan large genomic and image
datasets and predict the optimal approach for cancer screening,
diagnosis, prognosis, and treatment. CATOS allows for a
customized approach for an individual’s cancer, and the
development of novel diagnostic assays for patients. The CATOS
system has been proven to be effective and accurate for precision
diagnostics, with 76 published scientific articles and more than
4,492 citations. The initial CATOS product, a 7-gene lung cancer
assay (CATOS-LU), has been validated in 1,641 patients,
including a randomized Phase III clinical trial. The FDA has
classified CATOS-LU as a “Novel Technology” (under review).
The CATOS software platform has over 53,000 browses, which
will be upgraded for premium paid use. In addition, CATOS can
be used for drug discovery, by identification of new cancer
treatment options from drugs that are currently approved for use
for other diseases, which can be safely repurposed for cancer
treatment. Using our software, we have discovered and filed
patents for 8 diagnostic assays and 21 ‘repurposed’ compounds.
