Aradigm doses first patient in Phase III trial of ciprofloxacin to treat non-cystic fibrosis bronchiectasis

"I am pleased that our team has achieved this very important milestone, which also further strengthens our financial position," said Nancy Pecota, Chief Financial Officer, Aradigm.

The Phase III clinical program for Pulmaquin in BE consists of two worldwide, double-blind, placebo-controlled pivotal trials (ORBIT-3 and ORBIT-4) that are identical in design except for a pharmacokinetics sub-study to be conducted in one of the trials.

Each trial will enroll approximately 255 patients into a 48 week double blind period consisting of 6 cycles of 28 days on treatment with Pulmaquin or placebo plus 28 days off treatment, followed by a 28-day open label extension in which all participants will receive Pulmaquin (total treatment duration approximately one year).

The superiority of Pulmaquin vs. placebo during the double blind period will be evaluated in terms of the time to first pulmonary exacerbation (primary endpoint), while key secondary endpoints include the reduction in the number of pulmonary exacerbations and improvements in the quality of life measures. Lung function will be monitored as a safety indicator. The first patient in the ORBIT-3 trial was dosed on April 29, 2014.

Bronchiectasis is a severe, chronic and rare disease characterized by abnormal dilatation of the bronchi and bronchioles, frequently associated with chronic lung infections. It is often a consequence of a vicious cycle of inflammation, recurrent lung infections, and bronchial wall damage.

Non-CF BE represents an unmet medical need with high morbidity and mortality that affects more than 110,000 people in the U.S. and over 200,000 people in Europe. There is currently no drug approved for the treatment of this condition
