About Pulmaquin

Ciprofloxacin, available in oral and intravenous formulations, is a widely prescribed antibiotic. It is used to treat acute lung infections and is often preferred because of its broad-spectrum antibacterial activity against various bacteria, such as Pseudomonas aeruginosa. Pulmaquin is a dual release formulation composed of a mixture of liposome encapsulated and unencapsulated ciprofloxacin. It is being evaluated in two Phase III studies to determine its safety and effectiveness as a once-a-day inhaled formulation for the chronic treatment of non-CF BE. The ORBIT-3 study began dosing patients in April 2014 and ORBIT-4 will begin dosing patients in 1H 2014.

Pulmaquin has been extensively tested through preclinical studies and a Phase IIb study (ORBIT-2). Previous studies have demonstrated no significant clinical safety concerns.

Aradigm has been granted orphan drug designations for inhaled liposomal ciprofloxacin as well as for inhaled free ciprofloxacin for non-CF bronchiectasis in the U.S. In addition, the U.S. Food and Drug Administration (FDA) has designated Pulmaquin as a Qualified Infectious Disease Product (QIDP). The QIDP designation is granted for treatment of non-cystic fibrosis bronchiectasis (non-CF BE) patients with chronic lung infections with Pseudomonas aeruginosa.

In 2013, Aradigm granted an exclusive, world-wide license for the Company’s inhaled liposomal ciprofloxacin product candidates for the indication of non-CF BE and other indications to Grifols S.A. More information on the terms of this license may be found in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 filed with the SEC on March 13, 2014.
