Aradigm Corporation announced it has submitted its New Drug Application to the U.S. Food and Drug Administration for Linhaliq™ for the treatment of non-cystic fibrosis bronchiectasis patients with chronic lung infections with Pseudomonas aeruginosa. Aradigm received Orphan Drug Designation for liposomal ciprofloxacin for inhalation for the management of bronchiectasis and of Linhaliq for the management of bronchiectasis. Additionally, for Linhaliq, Aradigm was granted Qualified Infectious Disease Product (QIDP) Designation for the treatment of NCFBE patients with chronic lung infections with P. aeruginosa followed by Fast Track Designation. Linhaliq, formerly known as Pulmaquin®, is composed of a mixture of liposome encapsulated and unencapsulated ciprofloxacin. Ciprofloxacin, available in oral and intravenous formulations, is a widely prescribed antibiotic. It is used often to treat acute lung infections because of its broad-spectrum antibacterial activity against various bacteria, such as P. aeruginosa. There are currently no treatments approved for NCFBE patients to prevent and reduce the number of pulmonary exacerbations (PEs).
