SAN DIEGO – The 71st annual scientific sessions held by the American Diabetes Association (ADA; Alexandria, Virginia) commenced last Friday here in a somewhat different regulatory backdrop than last year thanks to FDA's release of a guidance dealing with a basic type of closed-loop artificial pancreas system. The meeting also followed in short order, however, an appearance on Capitol Hill by adolescent diabetics urging Congress to prod FDA into allowing more investigational closed-loop devices to move forward into clinical trials.
