French financial prosecutors have decided to drop a market-manipulation investigation into Sanofi, the drug company says, confirming an earlier report by La Lettre.

  • “We have always said that the financial information published by Sanofi was accurate and duly audited by two auditing firms,” Sanofi representatives say in an email
  • The case, opened in 2023, concerned the launch of blockbuster medicine Dupixent
  • Officials from Parquet National Financier didn’t immediately respond to a request for comment
  • NOTE: Sanofi Probed for Market Manipulation by French Authorities
