EUROPEAN CF CLINICAL TRIAL IN PAEDIATRIC PATIENTS BEGINS

Pharmaceutical company Pharmaxis (ASX:PXS) today announced that it has enrolled the first subject into its European paediatric clinical trial evaluating Bronchitol® in cystic fibrosis.

The Phase 2 trial being conducted in Europe and Canada is a requirement of Bronchitolˇ¦s earlier European marketing approval for adults and if positive will form part of an application to extend this approval to treat children and adolescents in the EU with cystic fibrosis.

The trial is a 27 week randomised, double-blind crossover investigation of Bronchitol administered twice daily in approximately 160 patients with cystic fibrosis. The trial is enrolling cystic fibrosis patients aged 6 to 17 years and will assess improvements in lung function, treatment induced sputum weight and safety.

Pharmaxis Chief Executive Officer Mr Gary Phillips said: ˇ§This clinical trial includes patients aged 6-17 who make up approximately one third of patients in the EU who could potentially benefit from Bronchitol. It utilizes a number of different design features to overcome some of the issues seen in this age group in the earlier phase 3 studies. We expect it will provide important additional evidence on the performance of Bronchitol in the paediatric and adolescent population.ˇ¨

Bronchitol is a precision spray-dried form of mannitol, delivered to the lungs by a specially designed, portable inhaler. The product is approved for marketing for patients aged over six years in Australia and for patients aged 18 years and over throughout the European Union.
