tacere-logo-150px.gifTacere Therapeutics strikes RNAi deal with Pfizer for up to $145M — San Jose, Calif.-based Tacere Pharmaceuticals, a biotech developing new drugs based on the gene-silencing technique known as RNA interference, struck a partnership deal with Pfizer that could be worth up to $145 million. The company’s release is here.

The deal involves Tacere’s leading drug candidate for hepatitis C. Known as TT-033, the drug consists of short stretches of RNA designed to trigger cellular mechanisms that shut down the activity of specific genes — an exciting but so far still unproven approach. In this case, TT-033 aims to shut down three separate parts of the hepatitis C genome, theoretically not only inactivating the virus, but also preventing the development of resistant viral strains.

Tacere is already co-developing TT-033 with Oncolys BioPharma of Japan, and in fact has deep Japanese roots, as the company also received its founding capital from Hokkaido Venture Capital of Sapporo, Japan. (Our coverage of the Oncolys deal is here.) The Pfizer deal appears to be complementary to Tacere’s previous agreement, as the Big Pharma will receive worldwide rights to TT-033 excluding Asian nations. Pfizer will fund all future development of the drug, and will make milestone payments to Tacere as development proceeds. TT-033 has not yet entered human testing.

Investors included Bay City Capital, Integral Capital Partners, Delphi Ventures and Onset Ventures.

Founded in 2005, Aragon develops tools and instruments intended to speed surgical procedures and to improve their safety. The company is working on two major classes of devices — “electrosurgical” instruments, which use electric current to stop bleeding, remove growths and cut tissue, and tools that improve the speed and safety of minimally invasive surgeries known as laparoscopies. Last September, Aragon launched its first product, the LapCap, which guides a needle used to inflate a patient’s abdomen with gas in order to reduce the risk of inaccurate placement and injury.
