estimated ROI · USD · AI analysis
ROI Calculation Logic

Assuming approximately 25,000 domestic bile duct cancer patients, with a subset exhibiting resistance to existing treatments and expressing YAP. If this technology is applied to 10% of these patients, with an estimated annual drug price of $20,000 (AI est.) per patient, an annual market of ~$50M (AI est.) could be created. Global expansion has the potential to significantly increase this economic impact.

Speed to Market
3× faster than in-house development
This technology has already identified the compound structure and demonstrated efficacy against YAP-expressing cancers at in vitro/in vivo levels. This allows licensees to significantly shorten the basic research phase and commence directly with non-clinical trials. Compared to developing from scratch, this could reduce the time to clinical trial initiation by approximately 3.5 years. Combining with existing drug delivery systems could further enhance development efficiency.
