Sanofi and Cheplapharm to create new strategic partnership in mature medicines

Paris, September 14, 2026. Sanofi and Cheplapharm, a European leader in well-established medicines, today announced their intention to create a strategic partnership under which Cheplapharm would take over from Sanofi a selection of 20 mature medicines and three manufacturing sites worldwide. In return, Sanofi will receive a 26.4% equity stake in Cheplapharm, building on a collaboration that started in 2014.
The partnership is based on a shared conviction: that innovative medicines and certain mature medicines have different needs and should benefit from operating models tailored to their specific manufacturing, regulatory and commercial requirements. Cheplapharm's specialized expertise will ensure these medicines continue to meet patients' needs throughout the next stage of their lifecycle.
