We didn't have to wait long for this predicted mergers and acquisitions (M&A) activity. Canadian-based Valeant Pharmaceuticals made a hostile takeover offer for Cephalon in late March 2011. The cash offer of about $5.7 billion was eventually rejected by Cephalon who believed the offer undervalued the company's key assets and prospects.

Pharmasset also announced that screening had begun in a Phase 2b study of PSI-7977.Biogen Idec's stock value jumped 33% following their news announcement about positive top-line results from the first of two pivotal Phase 3 clinical trials designed to evaluate their investigational oral compound BG-12 (dimethyl fumarate) as a monotherapy in people with relapsing-remitting multiple sclerosis. Results showed that BG-12, administered either twice or three times a day, met the primary study endpoint. Biogen also reported that it had signed a collaboration with Amunix for next-generation long-lasting blood factor products.
In the regulatory area, FDA gave the green light to the blockbuster biotech drug Benlysta, the first new lupus medicine to be approved by the agency in 56 years.
