In 2009, Medley Farma, the third largest pharmaceutical company in Brazil and a leading generics company in that country, was acquired for about $635 million. Sanofi outbid Teva Pharmaceuticals. The deal was approved by Brazil's antitrust authorities in May 2010. Later that year, Indian vaccine manufacturer Shantha Biotechnics was acquired for $784 million. In October Sanofi-Aventis announced that it would lay off about 1,700 US employees (about 25% of its US workforce) due to restructuring triggered by growing generic competition and other factors, and that the company would focus its US operations on diabetes, atrial fibrillation and oncology.
