Sanofi breaks ground on new state-of-the-art insulin manufacturing facility in Germany
Paris and Frankfurt, October 19, 2026. Sanofi today broke ground on a new state-of-the-art insulin manufacturing facility at its BioCampus in Frankfurt, Germany. The new facility will bring a new generation of insulin production to one of Sanofi’s largest integrated research and manufacturing sites, strengthening Sanofi’s long-term ability to provide a reliable supply of insulin to millions of people living with diabetes around the world.
Prime Minister of the State of Hesse Boris Rhein and Mayor of Frankfurt Mike Josef joined Belén Garijo, Chief Executive Officer of Sanofi, Brendan O’Callaghan, Sanofi Executive Vice President, Manufacturing & Supply and Chairman of the Supervisory Board of Sanofi in Germany, and Madeleine Roach, Country President of Sanofi in Germany, at today’s groundbreaking ceremony.
“Millions of people around the world rely on insulin every day, and our commitment to them is for the long term. With this new facility, we are investing in the next generation of insulin manufacturing in Europe, building on more than a century of expertise and a strong industrial footprint in Frankfurt. Maintaining the right conditions for investment and innovation will be essential to Europe’s future competitiveness,” said Belén Garijo, Chief Executive Officer, Sanofi.
Investing in the next generation of insulin manufacturing
The new facility will be built on a 36,000-square-meter footprint at the Sanofi BioCampus in Frankfurt, equivalent to approximately five football fields. Designed to meet the highest standards of quality and automation, it will leverage advanced digital technologies and artificial intelligence across manufacturing and quality processes.
Full production of insulin active pharmaceutical ingredient is planned for 2032, once the facility is fully licensed. Building on more than a century of manufacturing expertise in Frankfurt, the facility will combine advanced manufacturing technologies, automation and digital capabilities. Once operational, it will be among the largest and most advanced insulin manufacturing facilities in Europe and an important part of Sanofi’s global insulin supply network.
The Frankfurt BioCampus covers the entire insulin manufacturing value chain, from active pharmaceutical ingredient production to filling, device assembly, and packaging, with around 4,000 employees dedicated to insulin and approximately 20 insulin products supplied from the site.
A long-term commitment to people living with diabetes
More than 500 million people worldwide live with diabetes, and millions rely on insulin every day. With the number of people living with diabetes expected to rise to more than 800 million by 2050, and as the global insulin supply landscape evolves, reliable long-term insulin supply will remain essential.
Sanofi currently supplies insulin to approximately 15 million people in more than 100 countries each year. The new Frankfurt facility reflects Sanofi’s long-term commitment to people who rely on insulin every day and will help ensure its global manufacturing network is equipped to serve patients for decades to come.
Sanofi announced its plans for the new Frankfurt facility in August 2024. In September 2026, the European Commission approved public support from the German Federal Government, the State of Hesse and the City of Frankfurt under the European Union’s state aid framework.
