Business Model
What each company does and how it makes money
Silexion Therapeutics is a biopharmaceutical company that develops RNA interference-based cancer drugs using its proprietary LODER delivery platform to treat solid tumors. It generates revenue through research grants, partnerships, and potential future drug sales — though currently in pre-clinical and early clinical stages without commercial products. Its key competitive advantage is the LODER delivery system, which enables targeted, sustained release of RNAi therapeutics directly to tumor sites.
Regeneron Pharmaceuticals is a biotechnology company that discovers, develops, and commercializes innovative medicines for serious diseases. It generates revenue primarily from sales of its flagship products — EYLEA for eye diseases (~60% of revenue) and Dupixent for inflammatory conditions (~30%) — with additional income from collaborations and royalties. The company's competitive advantage lies in its proprietary VelocImmune technology platform for creating human antibodies and its deep expertise in genetic research, which enables rapid drug discovery and development.
