Aradigm Receives FDA Orphan Drug Designation for Liposomal Ciprofloxacin for Bronchiectasis

HAYWARD, Calif.--(HSMN NewsFeed)--Aradigm Corporation (OTCBB:ARDM ) today announced it has received orphan drug designation from the U.S. Food and Drug Administration (FDA) for an inhaled liposomal formulation of ciprofloxacin for the management of bronchiectasis (BE). Aradigm previously received orphan drug designation for the same formulation of ciprofloxacin for the management of cystic fibrosis in April 2006.

Aradigm's liposomal ciprofloxacin is an aerosolized formulation of this proven anti-infective drug that was designed to prolong its anti-infective properties in the lung in order to treat the related infections found in BE and cystic fibrosis patients, while minimizing the concentration of the drug in the rest of the body.

"We are very pleased with the orphan drug designation for an additional indication for our inhaled liposomal ciprofloxacin formulation. The orphan drug designation continues to support our strategy to help patients with severe respiratory disease," said Babatunde Otulana, M.D., Senior Vice President of Development at Aradigm.

Orphan drug designation is intended to encourage research and development of new therapies for diseases that affect fewer than 200,000 patients in the United States. As an orphan drug, liposomal ciprofloxacin is eligible for tax credits based upon its clinical development costs, as well as assistance from the FDA in guiding the drug through the regulatory approval process. The drug is currently in the preclinical stage of development. The designation also provides the opportunity to obtain market exclusivity for seven years from the date of NDA approval.

BE is a chronic necrotizing infection of the bronchi and bronchioles leading to or associated with abnormal dilatation of the airways. It is a relatively rare condition, affecting about 110,000 people in the United Sates, and results from a cycle of inflammation, recurrent infection, and bronchial-wall damage. Most patients require recurrent or chronic antibiotic treatment to suppress the lung infection, which is often due to Pseudomonas or other bacteria.
