Case Study: Sanofi reduces CSR writing time with Yseop

Helping global healthcare leader Sanofi get drugs to market faster

Sanofi, the global healthcare and pharmaceutical leader, wanted to speed up drug development by streamlining its Clinical Study Report (CSR) generation process while ensuring reports remained 100% accurate, fully traceable, and compliant. To help address this challenge, Sanofi worked with Yseop and its natural language generation-based medical writing solution.

Yseop co-built a human-in-the-loop medical writer assistant with Sanofi that automatically drafts CSR text for review and can mine clinical data for rule-based analysis. The solution automated two major CSR sections across phase 1 and 3 studies in pharma, oncology, and vaccines, reducing writing time by 30% on those sections and allowing employees to focus on higher-value scientific work.
