When is it appropriate to use study data from outside the U.S. to support FDA applications? FDA's Center for Devices and Radiological Health ("CDRH") and Center Biologics Evaluation and Research ("CBER") recently published a new draft guidance entitled "Acceptance of Medical Device Clinical Data from Studies Conducted Outside the United States.
