Setback: AstraZeneca fails to win USFDA nod for combo lung disease therapy

The setback comes as AstraZeneca tries to catch up with domestic rival GlaxoSmithKline's Trelegy, which is delivered through inhaler Ellipta. That treatment pulled in 156 million pounds in sales last year in its use against COPD.

New Delhi: The U.S. Food and Drug Administration declined to approve AstraZeneca Plc's combination therapy to treat smoker's lung, the drugmaker said on Tuesday.

AstraZeneca said that it will work closely with the FDA regarding next steps, including submitting results from an additional late-stage study, which was not completed at the time the marketing application was submitted to the health regulator.

The therapy, PT010, was approved in Japan in June as a triple-combination therapy to relieve symptoms of chronic obstructive pulmonary disease (COPD), AstraZeneca said.

Colloquially known as smoker's lung, COPD is a progressively worsening and potentially deadly condition that affects more than 380 million people worldwide, primarily caused by smoking but also by occupational hazards such as air pollution or chemical fumes.

COPD is predicted to be the third leading cause of death by 2020, according to the British drugmaker.
