Regeneron

Regeneron Pharmaceuticals was founded in 1988 in Tarrytown, New York by Leonard Schleifer and George Yancopoulos. The company built its reputation on the Velocimmune platform—a proprietary humanized mouse technology that dramatically accelerates the discovery of human antibodies—and has used it to produce multiple best-in-class biologics across inflammatory, oncologic, and eye diseases.\n\nRegeneron's commercial portfolio is anchored by Dupixent (dupilumab), developed with Sanofi, which has become one of the best-selling drugs globally with over $14 billion in 2024 revenues, treating atopic dermatitis, asthma, COPD, and other type-2 inflammatory conditions. Additional key products include Eylea (aflibercept) for macular degeneration and PRALUENT for cardiovascular cholesterol lowering. The company's bispecific antibody pipeline, cancer vaccines in collaboration with BioNTech, and gene therapy programs represent its next growth wave.\n\nRegeneron reported over $14 billion in annual revenue in 2024 and maintains a world-class science culture, consistently ranking among the top companies for R&D productivity and employee satisfaction. Its Tarrytown campus houses more than 10,000 employees and remains a leading independent US biopharmaceutical innovator.
