Trius Therapeutics (Nasdaq: TSRX) was a biopharma company based in San Diego, CA that focused on the development ofantibiotics.[1]
Thelead compound from Trius,tedizolid phosphate (formerly torezolid phosphate, TR-701), successfully completed its first Phase 3 clinical trial (ESTABLISH 1) in acute skin and skin structure infections (ABSSSI).[2] It is a once daily, IV and oral, oxazolidinone being developed for the treatment of serious gram-positive infections, including those caused bymethicillin-resistantStaphylococcus aureus (MRSA).[3] The Phase 3 trials are being conducted under a Special Protocol Agreement with the US Food and Drug Administration and are using the draft FDA guidance of cessations of lesion spread at 48–72 hours as the primary endpoint.[4] In the ESTABLISH 1 Study, 200 mg of Tedizolid given for a short course of therapy (six days) was shown to be safe, well tolerated and was as effective as the traditional length of therapy with linezolid (600 mg for ten days).[5] Additionally, Tedizolid was shown to have fewer treatment-related side effects than linezolid and significantly fewer GI side effects.[6]
Trius was planning the second Phase 2 trial and expects to report results around the end of Q1 2013 and planned to submit an NDA to the FDA for the drug in the second half of 2013.[7]
