Merck acquired SmartCells to gain access to its glucose-responsive insulin technology, which could substantially reduce the risk of hypoglycemia compared to current insulin analogues. Nancy Thornberry, Senior VP of Research at Merck, confirmed that SmartCells is an important early-stage program that has the potential to be a "game changer" in diabetes treatment if successful. Merck sees diabetes as a core research area and remains committed to bringing innovative new products to market.
