Sanofi, Abbott sue Glenmark over Tarka patent
MUMBAI, India Sanofi Aventis and Abbott have filed a lawsuit against Glenmark Pharmaceuticals in the U.S. District Court of New Jersey, according to reports. The lawsuit is to prevent Glenmark from manufacturing Trandolapril/Verapamil Hydrochloride, the generic of the anti-hypertensive drug Tarka.
The two companies are seeking a court order blocking Glenmark from selling the drug until the patent expires in 2015. Glenmark believes it is the only applicant to have filed an application for this product with a paragraph IV certification. If Glenmark successfully challenges the patent, it will be entitled to a 180-day exclusivity period.
The product had sales of $100 million in the U.S.

Biogen’s lack of buyer interest triggers stock price dive
CAMBRIDGE, Mass. Biogen has reported that after two months of looking for a potential buyer, it has turned up no serious offers, which led to a 27 percent drop in the company’s shares, according to the Wall Street Journal.
Biogen said in a statement that it “did not receive any definitive offers to purchase the company” and would abandon exploration of a sale. Within a few minutes of the announcement, Biogen lost nine months of increasing business by buyout rumors.
Pharmaceutical firms may have been discouraged by Biogen’s high price—its market value had grown to $25 billion after the company announced its intention to sell. Last month, Sanofi-Aventis’ chief executive called Biogen’s price “a little high.”
Biogen has three main drugs on the market—Avonex and Tysabri for multiple sclerosis and Rituxan for cancer and rheumatoid arthritis. Some analysts said uncertainties about the future of the drugs were too great for buyers. Tysabri has been linked to a rare brain disorder, prompting close regulatory scrutiny.
The stock price fell from $75.88 to $55.50 on the Nasdaq Stock Market.
