Sanofi SA is to acquire Blueprint Medicines Corp, expanding its immunology pipeline with a marketed product for systemic mastocytosis, a rare blood disorder that can affect multiple systems in the body. Sanofi is to pay $129 per share in cash for the US company, representing a deal value of $9.1 billion at the transaction close in the third quarter. This figure could rise to $9.5 billion if one of the company’s clinical programmes meets specific development and regulatory milestones.
