ROI Calculation Logic

GM1 Gangliosidosis is a rare disease with limited existing treatments, allowing for high drug pricing. Assuming an annual treatment cost of ~$100K–$500K (AI est.) per patient, with hundreds of patients domestically and thousands globally, even a 10% market penetration could lead to annual sales of ~$65M–$650M (AI est.). This reflects the high market value of this technology in a market with few existing treatment options.

Speed to Market
4× faster than in-house development
This technology identifies specific compound groups as active ingredients for GM1 Gangliosidosis, eliminating the need for de novo compound discovery. This significantly shortens the initial research phase of new drug development, which typically takes over 10 years. With potentially established safety profiles for existing compounds, certain preclinical and toxicology studies could be streamlined, accelerating market entry by an estimated 7.5 years.
