cure rate compared to a 79.8% cure rate seen with the combination of piperacillin/tazobactam. The study also highlighted that resistance to piperacillin/tazobactam in bacteria causing pneumonia was higher than doripenem, especially among strains of Pseudomonas aeruginosa and Klebsiella pneumoniae.

A second study demonstrated that 500 mg of doripenem administered intravenously every eight hours (500 mg IV q8h) was as clinically effective and well tolerated as standard therapy with imipenem given as 500 mg intravenously every six hours (500 mg IV q6h) or 1 g every eight hours (1 g IV q8h) in patients with ventilator-associated pneumonia, including in high-risk patients, such as the elderly. Overall clinical cure rates were 68.3% for doripenem and 64.8% for imipenem. For those patients with Pseudomonas aeruginosa infection, doripenem demonstrated a 65% clinical cure rate compared to a 36% clinical cure rate seen with imipenem.

"These studies demonstrate that doripenem may be effective against a major cause of nosocomial pneumonia, Pseudomonas aeruginosa, which is one of the most difficult bacteria to treat," said Michael Niederman, M.D., Professor of Medicine, State University of New York at Stony Brook and Chairman of the Department of Medicine at Winthrop University Hospital in Mineola, New York. "Additionally, these troubling bacteria demonstrated a low rate of resistance to doripenem, which is an important factor in determining which antibiotic may work most effectively against the infection."

The use of doripenem in the treatment of nosocomial pneumonia, including ventilator-associated pneumonia, is under standard regulatory review in the United States and Europe. These data, along with the regulatory submissions, demonstrate the ongoing commitment of Johnson & Johnson Pharmaceutical Research & Development, L.L.C., to developing novel drugs for the anti-infective market.
