TITUSVILLE, N.J., October 3, 2023 – Janssen Pharmaceuticals, Inc. (Janssen), a Johnson & Johnson Company, today announced a development and commercialization agreement with Sanofi for Janssen’s extraintestinal pathogenic Escherichia coli (ExPEC) investigational vaccine program. The lead vaccine candidate is currently being evaluated in the Phase 3 E.mbrace study for the prevention of invasive E. coli disease (IED) in adults aged 60 years and older.

IED occurs when bacteria that normally reside in the intestines leave the intestinal tract and infect other parts of the body. This can result in a range of infections that can be serious and life-threatening for adults over 60, including bacteremia (blood infections) and sepsis. ExPEC is a leading bacterial cause of sepsis.2

“We’re committed to addressing the unmet need for a vaccine to protect against IED, which affects nearly 10 million adults each year, has only limited therapeutic options available and can cause life-threatening infections,” said Penny Heaton, M.D., Global Therapeutic Area Head, Infectious Diseases & Vaccines, Janssen Research & Development, LLC. “This agreement will enable us to accelerate the development and potential commercialization of this important preventive option.”

The strategic agreement, which is subject to certain customary closing conditions, combines the research and development strength of Janssen with the global commercial vaccine expertise of Sanofi to advance the ExPEC vaccine development program. Under the terms of the agreement, both parties will co-fund current and future research and development costs. Sanofi will pay USD $175 million upfront to Janssen, followed by development and commercial milestones. There will be a profit-share arrangement in the U.S., EU4 (France, Germany, Italy, Spain) and the UK. In the rest of the world (ROW), Janssen will receive tiered royalties and sales milestones. Payments are subject to customary clearances.
