Sanofi and Aetion launch enterprise-wide collaboration to advance regulatory submissions using real-world evidence

BRIDGEWATER, NJ and NEW YORK – November 20, 2019 - Sanofi announced today an enterprise-wide collaboration with health care technology company Aetion that will integrate Sanofi’s real-world data platform, DARWIN, with the Aetion Evidence Platform® with the objective of advancing more efficient use of real-world evidence (RWE), facilitating regulatory-grade studies with deep transparency, and unlocking access to new real-world data.

Both companies have invested in RWE platforms, recognizing the pressing need for accurate, fast, and cost-effective research and the important role RWE could play in meeting this need. Sanofi’s DARWIN compiles and analyzes de-identified data from hundreds of millions of patients across disease states, while Aetion’s platform analyzes real-world data to produce transparent, rapid, and scientifically validated answers about the effectiveness, safety, and value of drugs. By combining these platforms, Sanofi is seeking to elevate its capabilities in conducting regulatory-grade analytics, opening new doors for the development and application of medical treatments.

“Today marks another important step in Sanofi’s digital transformation,” said Bernard Hamelin, MD, MSc, MBA, Global Head of Medical Evidence Generation, Sanofi. “By integrating these platforms, we strive to make faster, more informed decisions with the potential to lead to first-in-class and best-in-class treatments that could change the practice of medicine.”

Real-world evidence offers a view of clinical practice outside of the experimental setting, providing an opportunity to inform clinical trial development and supplement trial data with evidence of actual product use in the health care system.

“Our work with Sanofi further validates the value and potential for real-world evidence in drug development,” said Carolyn Magill, Chief Executive Officer of Aetion. “Our companies share a common goal of using the best available data to get the right treatment to the right patient as quickly and efficiently as possible.”

This collaboration between Sanofi and Aetion demonstrates leadership during a critical time.  Real-world evidence is expected to play a key role in transforming the health care ecosystem, with the U.S. Food and Drug Administration (FDA) recently prioritizing efforts to incorporate RWE as a companion to clinical trial data to aid in regulatory decision making. The FDA will release its draft RWE guidance before the end of 2020.
