The US Food and Drug Administration has issued a ‘complete response letter’ to GlaxoSmithKline Plc rejecting the company’s application for a third indication for mepolizumab (Nucala). The application was to use the drug as an add-on treatment for patients with chronic obstructive pulmonary disease (COPD).
Announcing the rejection on 7 September, GSK said the FDA is requiring more data to support the proposed indication.
