Trius Therapeutics to Present Data From Tedizolid Clinical Studies at IDWeek Conference

SAN DIEGO, Oct. 16, 2012 (GLOBE NEWSWIRE) -- Trius Therapeutics, Inc. (Nasdaq:TSRX) announced today that the results of multiple studies from its lead antibiotic drug candidate, tedizolid phosphate, will appear in poster presentations at the inaugural IDWeek conference, a joint meeting of the Infectious Disease Society of America, the Society for Healthcare Epidemiology of America, the HIV Medicine Association, and the Pediatric Infectious Disease Society, in San Diego from October 17th to 21st. Two tedizolid-related posters have been accepted for presentation, including clinical and safety results.

The clinical abstracts examine the hematological effect of tedizolid and linezolid in patients with acute bacterial skin and skin structure infections (ABSSSI), as well as pharmacokinetics in an adolescent population. The abstracts include one poster presentation from the ESTABLISH 1 trial (formerly known as the TR-701-112 trial) summarizing the detailed hematological results from Trius' first Phase 3 trial of tedizolid in patients with ABSSSI. This marks the first time these data are being presented at a major medical meeting. Top-line results for the ESTABLISH 1 trial, reported in December 2011, showed that tedizolid achieved all primary and secondary efficacy outcomes after a short course of therapy, and showed significant improvements in key safety and tolerability measurements in the complete study population versus the comparator linezolid (Zyvox®). This is the first of two registrational studies for tedizolid.

Tedizolid is the Company's lead product candidate. It is a once daily, IV and orally administered oxazolidinone being developed for the treatment of serious gram-positive infections, including those caused by methicillin-resistant Staphylococcus aureus (MRSA).

The presentations are as follows:

Friday, October 19th

Poster Session – Antimicrobial Chemotherapy (12:30 p.m. – 2:00 p.m.)

  • 789: A Comparative Evaluation of Adverse Platelet Outcomes among Patients with Acute Bacterial Skin and Skin Structure Infections Receiving Tedizolid Phosphate and Linezolid; T. Lodise, C. De Anda, E. Fang.

Saturday, October 20th
