Sanofi to create new industry leading European company to provide active pharmaceutical ingredients (API*)

Paris - February 24, 2020 – Sanofi plans to create a major leading European company dedicated to the production and marketing to third parties of active pharmaceutical ingredients (API), which are the essential molecules responsible for the beneficial effects used in the composition of any drug. The project consists of creating a standalone company which would combine Sanofi’s API commercial and development activities with six of its European API production sites : Brindisi (Italy), Frankfurt Chemistry (Germany), Haverhill (UK), St Aubin les Elbeuf (France), Újpest (Hungary) and Vertolaye (France).

With increasing medicine shortages that critically impact patient care, the new entity would contribute to supporting and securing API manufacturing as well as supply capacities for Europe and beyond. In Europe, the new API industry champion is expected to help in balancing the industry’s heavy reliance on API sourced from the Asian region³.

The new company would rank as the world’s second largest API company with approximately €1 billion in expected sales by 2022. It is expected to include 3,100 skilled employees and to be headquartered in France. A planned IPO on Euronext Paris would be evaluated with a decision expected by 2022, subject to market conditions.

Philippe Luscan, Executive Vice President, Global Industrial Affairs at Sanofi, said “Based on the expertise and experience built over decades within our industrial network, this new entity would help ensure a greater stability in supplying drugs to millions of patients in Europe and beyond. With this endeavor, this new entity would be agile as a standalone company, and able to unlock its growth potential, especially in capturing new third-party sales and all the opportunities of a market growing at a pace of 6 % per year⁴.”

By operating independently, the new entity plans to increase its sales to third parties and to expand its partnerships with other pharmaceutical companies in order to take advantage of new growth opportunities and have the ability to deftly adapt to customer needs. The new company would be uniquely positioned to benefit from its significant competitive strengths, including a broad portfolio of both volume and niche products, high standards of quality, competitive pricing, state-of-the-art industrial capabilities and technologies across Europe (including France, Italy, Germany, Hungary, and the United Kingdom) as well as leveraging an extensive commercial network covering more than 80 countries.

Sanofi is fully committed to the new company’s success and intends to establish a long-term customer relationship with the new API supplier and to hold a minority stake of approximately 30% in the new company. To provide the optimal conditions for success, Sanofi intends the new company to be debt free in order to maximize its future investment capacities, and is committed to remaining an important customer.

Sanofi joins forces with U.S. Department of Health and Human Services to advance a novel coronavirus vaccine

PARIS – February 18, 2020 – Sanofi Pasteur, the vaccines global business unit of Sanofi, will leverage previous development work for a SARS vaccine which may unlock a fast path forward for developing a COVID-19 vaccine. Sanofi will collaborate with the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response, expanding the company’s long-standing partnership with BARDA.

COVID-19 belongs to a family of coronaviruses that can cause respiratory disease. In late 2002, the SARS (severe acute respiratory syndrome) coronavirus emerged and then largely disappeared by 2004. Sanofi plans to further investigate an advanced pre-clinical SARS vaccine candidate that could protect against COVID-19.

“Addressing a global health threat such as this newest coronavirus is going to take a collaborative effort, which is why we are working with BARDA to quickly advance a potential vaccine candidate,” said David Loew, Global Head of Vaccines at Sanofi. “While we are lending our expertise where possible, we believe the collaboration with BARDA may provide the most meaningful results in protecting the public from this latest outbreak.”

Sanofi to utilize innovative recombinant technology platform

Sanofi will use its recombinant DNA platform to produce a 2019 novel coronavirus vaccine candidate. The recombinant technology produces an exact genetic match to proteins found on the surface of the virus. The DNA sequence encoding this antigen will be combined into the DNA of the baculovirus expression platform, the basis of Sanofi’s licensed recombinant influenza product, and used to rapidly produce large quantities of the coronavirus antigen which will be formulated to stimulate the immune system to protect against the virus.

“Emerging global health threats like the 2019 novel coronavirus require a rapid response,” said BARDA Director Rick A. Bright, Ph.D. “By expanding our partnership with Sanofi Pasteur and leveraging a licensed recombinant vaccine platform, we hope to speed development of a vaccine candidate to protect against a new virus.”

Sanofi uniquely positioned in search for a coronavirus vaccine

In non-clinical studies, the SARS vaccine candidate was immunogenic and afforded partial protection as assessed in animal challenge models. This development work by Protein Sciences (acquired by Sanofi in 2017) provides a head start in expediting a COVID-19 vaccine. Additionally, since there is a licensed vaccine based on this platform this will allow for research and materials to be produced relatively quickly for clinical testing. Sanofi’s platform also has the potential to manufacture large quantities of the vaccine candidate.

Sanofi’s long-standing commitment to protecting public health

This agreement with BARDA marks another milestone in Sanofi’s ongoing contributions to help fight public health threats. Sanofi continues to actively explore potential opportunities where the company’s deep vaccine experience and innovative technologies may contribute to addressing the coronavirus public health situation, including sharing Sanofi’s vaccine research and development experience with the Coalition for Epidemic Preparedness Innovations.

In December 2019, Sanofi also entered into an agreement with BARDA to establish state of the art facilities in the U.S. for the sustainable production of an adjuvanted recombinant vaccine for use in the event of an influenza pandemic and based on the same technology platform that will be used for the COVID-19 program.
