Optimer said fidaxomicin is the first in a new class of antibiotics called macrocycles, which inhibit the bacterial enzyme RNA polymerase, resulting in the rapid killing of C difficile.
The aim of the multi-center, randomized, double-blind clinical trial was to evaluate the safety and efficacy of the company’s novel antibiotic fidaxomicin as a treatment for patients with CDI.
Results have shown that fidaxomicin significantly reduces recurrence rates and increased global cure rates when compared to vancomycin – the only treatment approved by the US Food and Drug Administration for CDI.
The article titled, "Fidaxomicin versus Vancomycin for Clostridium difficile Infection," appears in the 3 February, 2011 issue of The New England Journal of Medicine journal.
