Pharmaxis files new drug application for bronchial challenge test

Pharmaxis Inc, a wholly owned subsidiary of Pharmaxis Ltd, a respiratory specialty pharmaceutical company, has filed a new drug application, electronically, with the FDA for Aridol. Bronchial challenge tests are designed to assess bronchial hyperresponsiveness, an important marker in the diagnosis and assessment of asthma.

Aridol will be a standardized test kit containing proprietary dry-powder mannitol (a naturally occurring sugar alcohol), prepared for delivery to the lungs using a proprietary hand-held inhaler.

The goal of Aridol is to provide physicians and healthcare professionals with an objective measure of active airway inflammation through an easy-to-use, single-use test for asthma care and assessment in a variety of healthcare settings, said Pharmaxis.

Aridol is approved for sale in Australia, major European countries and Korea. It is the first and only bronchial challenge test approved Europe-wide, said Pharmaxis.

Brett Charlton, medical director at Pharmaxis Ltd, said: “Aridol is designed to measure bronchial hyperresponsiveness that corresponds with airway inflammation, an important underlying component of asthma.”
