SWIFTWATER, Pennsylvania, November 9, 2010 /PRNewswire via COMTEX/ -- Sanofi Pasteur, the vaccines division of sanofi-aventis Group , announced today that the U.S. Food and Drug Administration (FDA) has granted fast-track designation to the company's investigational Clostridium difficile vaccine candidate. The fast-track program of the FDA is designed to facilitate the development and expedite the review of new drugs and vaccines that are intended to treat or prevent serious or life-threatening conditions and demonstrate the potential to address unmet medical needs.
The incidence of Clostridium difficile infection (CDI) has increased significantly in recent years in both North America and Europe. CDI-related treatments in these two regions of the world are estimated to be costing more than $7 billion a year. The recent emergence and spread of a hyper-virulent strain of C. difficile further highlights the importance of preventing CDI.
C. difficile is among the most common causes of nosocomial (hospital-acquired) infection in North America and Europe. Current treatment of C. difficile infection involves the use of one of the two antibiotics recommended for CDI management.
"Our C. difficile vaccine candidate is in phase II," according to Michel DeWilde, Ph.D., Senior Vice President, Research and Development. "The FDA fast-track designation recognizes that a C. difficile vaccine could address an important unmet medical need. Under this program," he explained, "the FDA can accept for review completed portions of the licensing application prior to receipt of the entire application."
About Clostridium difficile infection
C difficile is an anaerobic spore-forming bacterium, present asymptomatically in approximately 60 percent of infants but only approximately three percent of healthy adults. When the natural microbial flora of the gut is disturbed, usually as a result of antibiotic treatment for other infections, and a patient ingests C difficile spores, the bacteria can multiply and release the two toxins which cause a broad range of gastrointestinal symptoms in humans known collectively as CDI.
Hospital-acquired infections caused by C difficile are a considerable problem in many industrialized countries including the U.S., Canada, and Europe. It is estimated that there are about 500,000 cases of CDI in the US alone[1], with annual costs to the healthcare system of $3.2 billion[2]. In the EU the healthcare costs of CDI are estimated to be around $4.4 billion per year.[3] Additional information is available at the US Centers for Disease Control and Prevention and UK Health Protection Agency C difficile information pages[1,4].
