Waiting period expires in Merck & Co's Sirna buy
USA-based drug major Merck & Co says that the Hart-Scott-Rodino antitrust waiting period in relation to its $1.1 billion acquisition of fellow US firm Sirna Therapeutics (Marketletter November 6, 2006) has expired. Merck added that the deal will broaden its involvement in the emerging field of RNA interference-based therapeutics, making particular reference to Sirna's development of treatments for conditions such as age-related macular degeneration, hepatitis C infection and asthma.
The merger, which is expected to close in late December or early January, is still subject to customary conditions including approval by holders of Sirna's common stock.
