Trius Announces Notice of Allowance of U.S. Patent Application Related to
Tedizolid Phosphate Combination With Daptomycin
SAN DIEGO, May 13, 2013 (GLOBE NEWSWIRE) -- Trius Therapeutics, Inc.
(Nasdaq:TSRX), a biopharmaceutical company focused on the discovery,
development and commercialization of innovative antibiotics for serious
infections, announced today that it has received a Notice of Allowance from
the U.S. Patent and Trademark Office (USPTO) on an application related to its
tedizolid phosphate patent portfolio. This newly allowed patent application
protects a therapeutic combination of the experimental medicine tedizolid
phosphate with a currently available antibiotic daptomycin. Data show that
together, the medicines can uniquely prevent the development of daptomycin
non-susceptible bacterial strains such as methicillin-resistant Staphylococcus
As detailed in the patent application, tedizolid phosphate, at concentrations
substantially below its current therapeutic dose to treat skin infections,
unexpectedly prevents the formation of daptomycin resistant mutants of
Staphylococcus aureus. Tedizolid appears to be unique in this mutant
prevention activity given that seven other medicines tested, including
linezolid, the only other drug of the same class as tedizolid, failed to show
the same mutant prevention activity.
"MRSA bacteremia is a potentially fatal disease with limited treatment
options," said Ralph Corey, M.D. Professor of Medicine and Infectious Diseases
at Duke University. "As a clinician who treats bacteremia patients, I am
concerned by the growing resistance to one of our last effective treatment
options, daptomycin, and welcome this news that tedizolid phosphate may
prevent daptomycin resistance when used in a combination therapy."
"Given the recent positive Phase 3 results of tedizolid phosphate for the
treatment of skin infections, we are eager to examine its potential, whether
alone or in combination with other medicines, for the treatment of
bacteremia," said Jeffrey Stein, Ph.D., President and Chief Executive Officer
of Trius. "Most importantly, this patent, coupled with the results of our
long-term safety studies, provide us with guidance on how best to expand the
development of tedizolid phosphate to treat patients with severe bacterial
infections requiring sustained treatment."
