- Sanofi will lay off 229 workers in Massachusetts, according to a filing with the state's Executive Office of Labor and Workforce Development.
- The affected workers had been employed at Blueprint Medicines, a Cambridge-based biotech that Sanofi acquired in a $9.1 billion deal in July 2025.
- Sanofi is one of Massachusetts' largest pharmaceutical employers, giving the cuts outsized weight in the state's life-sciences labor market.
- The job eliminations are scheduled to occur between Oct. 9 and late June 2027, per the state filing.
Why it matters: A year after paying $9.1 billion for Blueprint Medicines, Sanofi is eliminating 229 of the roles it gained in the deal — and the cuts are phased across roughly nine months (Oct. 9 to late June 2027), signaling a drawn-out restructuring of the acquired company's workforce rather than a one-time event.
