ROI Calculation Logic

The global pancreatic cancer treatment market is estimated at ~$8B (AI est.). Assuming this technology improves response rates by 20% and contributes to improved long-term patient survival, and if treatment duration is reduced by an average of 10% compared to conventional protocols, it could generate an annual economic impact of ~$150M–$600M (AI est.) through reduced annual medical costs and increased productivity from patient reintegration into society.

Speed to Market
2× faster than in-house development
This technology focuses on combining existing anti-cancer drugs: sirolimus, gemcitabine, and TS-1. These drugs are already approved, with established safety profiles, pharmacokinetics, and basic efficacy data. This could shorten some non-clinical trials and reduce the scope of Phase I clinical trials compared to novel compound discovery. Leveraging known drug information significantly reduces early-stage development risks and uncertainties, potentially shortening the time to market.
