News Release - November 27, 2006
FDA Accepts as "Complete Response" Oscient Pharmaceuticals' Submission Following FACTIVE Approvable Letter for Five-Day CAPWALTHAM, Mass.--(HSMN NewsFeed)--The U.S. Food and Drug Administration (FDA) has accepted as complete Oscient Pharmaceuticals Corporation's (Nasdaq: OSCI ) response to the FACTIVEŽ (gemifloxacin mesylate) tablets approvable letter for the application seeking approval for the five-day treatment of community-acquired pneumonia of mild to moderate severity (CAP). FACTIVE is currently approved by the FDA for the five-day treatment of acute exacerbations of chronic bronchitis (AECB) and the seven-day treatment of CAP.
"We are looking forward to working with the FDA through this final phase of review of our five-day CAP application," stated Steven M. Rauscher, President and CEO.
The NDA for the five-day treatment of CAP contained data from a successful Phase III trial completed in 2005 comparing a five-day and seven-day treatment with FACTIVE 320 mg once-daily for CAP in 510 patients. That study demonstrated strong clinical response rates at follow up (the primary endpoint) in both arms. Currently, no fluoroquinolone is approved for the five-day treatment of both AECB and CAP. Community-acquired pneumonia is a common and serious illness in the United States with three to four million cases per year, resulting in approximately one million hospitalizations and 40,000 deaths annually. Pneumonia is the most common cause of death due to an infectious disease.

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.
