The present listing shows this status of currently enrolling. New sites in the United States are expected to open within the coming year. At that time the answers to some questions, such as "Studies FDA regulated drug" will change because the basis for FDA regulation will reside on the presence of US sites and the use of US manufactured drug, whereas at this time the drug is not of US manufacture, and the trial is not currently conducted in the United States. This registration is being posted at this time to prepare to meet United States FDAAAA registration requirements.
