Pharmaxis Ltd U.S. Phase III Aridol Trial Closed

SYDNEY, Australia, Aug. 28 /Xinhua-PRNewswire-FirstCall/ -- Specialist pharmaceutical company Pharmaxis Ltd is pleased to announce that the U.S. Aridol Phase III clinical trial in subjects with suspected asthma has finished recruitment. The trial was conducted in over 400 subjects in 30 hospitals throughout the U.S.

The trial compared Aridol with acknowledged methods for diagnosing airway responsiveness in subjects suspected of having asthma. Its design was based on discussions with the U.S. Food and Drug Administration (FDA). Initial data from the study, comparing the sensitivity and specificity of Aridol (mannitol) to identify exercise-induced bronchoconstriction, are expected to be available during the fourth quarter of this year.

Alan Robertson, Pharmaxis chief executive officer said: ‘A major impediment to better disease control in asthma is a lack of objective symptom measurements which often confounds accurate diagnosis. This large asthma trial supplements our earlier successful 650 patient study outside of the U.S. and the level of support amongst the U.S. respiratory physicians and their patients has been very encouraging. I expect this study to be an important part of our marketing application for Aridol with the FDA.’

The economic opportunity for a reliable, quick and objective lung function test to measure asthma severity is significant. Based on independent market research, the annual addressable market for Aridol in the U.S. and Europe includes the existing 400,000 bronchial challenge tests performed yearly, 2 million new tests for assisting the diagnosis of asthma and 16 million new tests performed by pulmonary specialists and primary care physicians for assisting the management of asthma.

Asthma affects more than 50 million people in the western world, and is one of the most common reasons for hospital admission and emergency room care.
