Our Data Sharing Commitments
Sanofi believes that making clinical trial data available to the research community promises to advance science and medicine, contributes to improvements in public health and improves knowledge about and trust in pharmaceutical drug development.

The concept of sharing data for research purposes is not new for Sanofi. Our company has a history of contributing to initiatives where data sets are pooled for research purposes.

The pharmaceutical industry as a whole demonstrated its support for sharing of clinical data when in July 2013, the members of the Pharmaceutical Research and Manufacturers of America (PhRMA) and the European Federation of Pharmaceutical Industries and Associations (EFPIA) developed and endorsed a set of Principles for Responsible Sharing of Clinical Trial Data
