San Diego, CA, Sept. 22, 2008 – Trius Therapeutics, Inc. today announced the initiation of Phase 2 testing of the oral form of its second-generation oxazolidinone antibacterial drug TR- 701. The multicenter trial will test the efficacy, safety and tolerability of once-daily doses of 200, 300 and 400 milligrams of Torezolid in complicated skin and skin structure infections (cSSSI) for five to seven days of treatment. The study follows the recently completed two-part Phase 1 study that tested the safety, tolerability and pharmacokinetics of Torezolid in single and multiple ascending doses for up to 21 days compared with Zyvox® (linezolid), the only marketed drug of the oxazolidinone class. In addition, separate food effect and microdialysis studies measuring the absorption of Torezolid in the presence and absence of food and the tissue penetration of the drug, respectively, have also been completed.
Results of the Phase 1 trials will be presented at the joint annual meetings of the Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) and the Infectious Diseases Society of America (IDSA) in Washington, D.C in October 2008.
“Our Phase 1 study results indicate that Torezolid will be a once-daily drug with the potential to offer patients several important advantages over linezolid as well as other marketed drugs,” said Philippe Prokocimer, M.D., Chief Medical Officer of Trius. “The intent of Phase 2 will be to validate these observations in a patient population and to select a therapeutic dosing regimen from the three doses being tested.”
“The growing epidemic of MRSA in the hospital and community leaves few viable treatment options for patients requiring an oral drug,” said Jeffrey Stein, Ph.D., Chief Executive Officer of Trius. “We believe that the once-daily dosing and short course of Torezolid therapy of five to seven days will offer a clinical advantage for patients and a potential pharmaco-economic advantage for insurers and others concerned about the increasing cost of healthcare.”
