MONMOUTH JUNCTION, N.J., Aug. 2, 2012 /PRNewswire/ -- Insmed Incorporated (Nasdaq CM: INSM), a biopharmaceutical company focused on developing inhaled therapeutics for serious diseases of the lung, today announced that the U.S. Patent and Trademark Office has issued a new composition of matter patent for ARIKACE^® (liposomal amikacin for inhalation), U.S. Patent No. 8,226,975. Amikacin is one of the aminoglycosides covered by the patent. The patent describes a system for treating or providing prophylaxis against pulmonary infections, and includes both of the compound's lead indications, cystic fibrosis (CF) patients who have Pseudomonas lung infections and patients who have non-TB Mycobacteria (NTM) lung infections.

The patent claims a new and unique inhaled treatment system and formulation in which the aerosol delivered to the lung contains a combination of both free unencapsulated aminoglycoside drug that is present outside the liposomes and aminoglycoside drug encapsulated inside liposomes. When delivered, ARIKACE contains both the free and liposomal encapsulated amikacin, which could be beneficial to patients in two ways. The delivery of free amikacin provides immediate bactericidal activity against the initial load of organisms, and the liposome encapsulated amikacin provides sustained bactericidal activity against persistent organisms.

The new patent provides exclusivity at least through May 18, 2027.

"The issuance of this second composition of matter patent expands our already extensive intellectual property position around ARIKACE," said Renu Gupta, M.D., Insmed's Executive Vice President of Development and Chief Medical Officer. "Our ARIKACE development plan is progressing well in both CF and NTM, and we are projecting top-line results in mid-2013 and fourth quarter 2013, respectively."
