Primary risk factors for CDI include broad-spectrum antibiotic use (such as cephalosporins and fluoroquinolones), advanced age (over 65) and exposure to emerging hyper-virulent strains (BI/NAP1/027, 078, 001) of C. difficile. Increasing incidence, higher treatment failures and recurrence with current therapies have resulted in greater awareness and concern of CDI among medical professionals and public health officials.
About FidaxomicinFidaxomicin is the first in a new class of antibiotics called macrocycles, which inhibit the bacterial enzyme RNA polymerase, resulting in the death of C. difficile. The narrow-spectrum profile of fidaxomicin may eradicate C. difficile selectively with minimal disruption to the normal intestinal flora, while the alternative antibiotics to treat CDI, metronidazole and vancomycin, disrupt the flora. Fidaxomicin may facilitate the return of normal physiological conditions in the colon which may be responsible for reducing CDI recurrence.
About Optimer PharmaceuticalsOptimer Pharmaceuticals, Inc. is a biopharmaceutical company focused on discovering, developing and commercializing hospital specialty products to treat serious infections and address unmet medical needs. Optimer has two anti-infective product candidates in development. Fidaxomicin is a narrow spectrum antibiotic being developed for the treatment of Clostridium difficile infection (CDI). Optimer has completed two Phase 3 trials of fidaxomicin for the treatment of CDI, demonstrating that fidaxomicin was statistically superior to vancomycin in global cure rate (defined as cure with no recurrence within four weeks of completing therapy) as well as statistically superior in reducing recurrences of CDI by up to 50% when compared with vancomycin, the only FDA approved product for CDI. Optimer has also successf
