By Adria Calatayud AstraZeneca said the U.S. Food and Drug Administration is pushing back its decision on whether to approve a new breast-cancer drug in order to review additional data provided by the company. The U.K. drugmaker said Wednesday that it provided additional analyses requested by the FDA in support of its application for the drug candidate, camizestrant, after the regulator's drugs advisory committee voted against its approval late last month.
