Aventis SA

What Aventis SA does

Aventis SA merged with Sanofi-Synthélabo in 2004 to form what is now Sanofi, a French-domiciled, publicly traded global biopharmaceutical company headquartered in Paris. The current entity operates as an R&D-driven, AI-powered biopharmaceutical business with a pipeline of 77 compounds in clinical development across five therapeutic areas — Immunology, Neurology, Oncology, Rare Diseases, and Vaccines — and 21 Phase 3 trials.

Its product portfolio includes newly approved specialty medicines such as Cenrifki (tolebrutinib), approved in the EU as the first disability-targeting therapy for secondary progressive multiple sclerosis without relapses, and Wayrilz, approved in Japan for immune thrombocytopenia. Underlying the franchise is an AI-integrated R&D platform that spans drug discovery, development, and manufacturing, complemented by technology platforms organized around each therapeutic area and a specialized vaccines manufacturing capability. A separate consumer healthcare brand, Opella, was spun off as a standalone entity, providing OTC distribution through pharmacies and retail channels.

The company generates revenue primarily from the sale of proprietary prescription biopharmaceuticals and vaccines across its five therapeutic areas, with pricing negotiated through government health systems, insurers, and healthcare institutions rather than publicly disclosed. GTM motion is large-scale enterprise field sales to hospitals, clinics, and physicians, supplemented by direct engagement with national and regional government health authorities for vaccine procurement and a separate consumer health channel via Opella. Operating geographies span France, the United States, China, Japan, and Ireland, with an External Innovation network covering North America, Europe, and China.
