Regulatory concern about potential QT-interval prolongation by serotoninreceptor antagonist antiemetics prompted product-label changes. The first-generation serotoninreceptor antagonist granisetron is available in oral (PO), intravenous (IV), and transdermal formulations. APF530 is a formulation that provides sustained release of granisetron when administered as a single subcutaneous (SC) injection. The Phase I study reported here evaluated effects of APF530 on electrocardiographic intervals.
