WALTHAM, Mass.--(BUSINESS WIRE)--June 28, 2006--The U.S. Food and Drug Administration (FDA) has informed Oscient Pharmaceuticals Corporation (Nasdaq: OSCI - News) that the FDA's Anti-Infective Drugs Advisory Committee will review the supplemental New Drug Application (sNDA) for FACTIVE® (gemifloxacin mesylate) tablets for the treatment of acute bacterial sinusitis (ABS) on September 12, 2006. The meeting will take place at the Hilton Gaithersburg Hotel, Salons A, B, and C, 620 Perry Parkway, Gaithersburg, Maryland. Additional details will be available in the Federal Register in the coming weeks.
The ABS sNDA seeks approval for the treatment of this infection with FACTIVE in a five-day treatment regimen. The sNDA contains data from five Phase III trials involving more than 1,800 patients receiving FACTIVE and 500 patients receiving a comparator. Of the 1,800 patients in the studies, more than 1,100 received FACTIVE for five days of treatment. The filing also includes safety data gathered from the post-marketing surveillance of FACTIVE since launch in September 2004 for the treatment of mild to moderate community-acquired pneumonia and acute bacterial exacerbations of chronic bronchitis.
The sNDA for the ABS indication was submitted in November 2005. The FDA notified the Company of its refusal to file the application in January of this year. After discussions with the FDA, and at the Company's request, the FDA filed the sNDA over protest. The FDA has set an action date for making a decision on the ABS sNDA of December 15, 2006.
Separately, an sNDA for the potential five-day treatment of community-acquired pneumonia of mild to moderate severity by FACTIVE is pending and the FDA has set an action date of September 21, 2006 for that application. FACTIVE is currently approved for the seven-day treatment of mild to moderate community-acquired pneumonia and the five-day treatment of acute bacterial exacerbations of chronic bronchitis.

Important Safety Information about FACTIVE Tablets
The most common (more than 2% incidence) drug-related side effects reported in FACTIVE clinical trials were diarrhea (3.6%), rash (2.8%) and nausea (2.7%). In clinical trials, drug-related rash was reported in 2.8% of patients receiving gemifloxacin and was more commonly observed in patients less than 40 years of age, especially females. The incidence of rash increases with treatment longer than the maximum-labeled duration of 7 days. In clinical trials, the discontinuation rate due to drug-related adverse events was similar for FACTIVE tablets and comparators (2.2% versus 2.1%, respectively).
Gemifloxacin is contraindicated in patients with a history of hypersensitivity to gemifloxacin, fluoroquinolone antibiotic agents, or any of the product components. Patients receiving marketed fluoroquinolones have reported serious and occasionally fatal hypersensitivity and/or anaphylactic reactions, peripheral neuropathy, antibiotic-associated colitis and tendon ruptures. Gemifloxacin should be discontinued immediately at the first sign of any of these events.
Fluoroquinolones may prolong the QT interval in some patients. Gemifloxacin should be avoided in patients with a history of prolongation of the QTc interval, patients with uncorrected electrolyte disorders (hypokalemia or hypomagnesemia), and patients receiving Class IA or Class III antiarrhythmic agents. In clinical studies with gemifloxacin, CNS effects have been reported infrequently. As with other fluoroquinolones, gemifloxacin should be used with caution in patients with known or suspected CNS diseases. If CNS reactions occur, gemifloxacin should be discontinued and appropriate measures instituted.
No significant drug-drug interactions were seen with theophylline, digoxin, oral contraceptives, cimetidine, omeprazole, and warfarin, although patients receiving a fluoroquinolone concomitantly with warfarin should be monitored closely. Drug-drug interactions include probenicid, sucralfate, antacids containing aluminum or magnesium, iron, multivitamins containing metal cations, and didanosine. The safety and effectiveness of gemifloxacin in children, adolescents (less than 18 years of age), pregnant women, and lactating women have not been established.
