During the third quarter of 2007, we reached an agreement with the United States Food and Drug Administration on the final design of our pivotal phase III clinical trial of prGCD, through the FDA's special protocol assessment (SPA) process and began enrolling patients in the trial. We have been treating patients since August 2007, and are initiating study centers worldwide.
