About this trial

The investigators are conducting a pilot open-label pre/post interventional trial in adolescents and adults with cystic fibrosis (CF) and abnormal glucose tolerance or early CF-related diabetes mellitus (CFRD) to assess the safety and efficacy of verapamil on beta cell function and dysglycemia.
