FDA advisory panel: Sept. 16, 2010

Drug/indication: Avastin for metastatic breast cancer

Approval decision date: Sept. 17, 2010

An FDA advisory panel said Gilenia was safe and effective as a treatment for multiple sclerosis, at a meeting on June 10.

Drug/indication: Dyloject for acute moderate-to-severe pain in adults

Approval decision date: Oct. 3, 2010

If approved, Dyloject will be the first IV nonsteroidal anti-inflammatory drug (NSAID) marketed in the U.S. as a single agent for the management of acute moderate-to-severe pain in adults since ketorolac in 1990. The active ingredient in Dyloject is diclofenac sodium, a widely prescribed oral NSAID. Dyloject was developed by Javelin Pharmaceuticals, which Hospira acquired in July.
