Sanofi agrees to buy Genzyme for £12.4bn
French pharmaceutical group Sanofi-Aventis has agreed to buy US biotech company Genzyme for $20.1bn (£12.4bn).
The acquisition of Genzyme will give Sanofi access to the market in drugs for the treatment of rare diseases.
Genzyme produces treatments for multiple sclerosis, cholesterol and rare genetic diseases.
Sanofi chief executive Christopher Viehbacher said in a statement: “This transaction will create a meaningful new growth platform for Sanofi-Aventis while expanding our footprint in biotechnology.”
Sanofi made a formal offer for Genzyme in August 2010 which Genzyme rejected, saying it did not take into account the company’s pipeline of potential medicines.
Under the terms of the new deal, Genzyme shareholders will also be entitled to future payments based on sales of Genzyme’s products, including multiple-sclerosis drug Lemtrada.
