About Insmed
Insmed Incorporated is a biopharmaceutical company dedicated to improving the lives of patients battling serious orphan lung diseases through the development and commercialization of inhalation therapies in orphan patient populations with critical unmet needs. Insmed's lead candidate, ARIKACE®, is engineered to deliver a proven and potent anti-infective directly to the site of serious lung infections to improve the efficacy, safety and convenience of treatment for at least two identified patient populations: cystic fibrosis (CF) patients with Pseudomonas aeuruginosa lung infections and patients with nontuberculous mycobacteria lung infections (NTM). Following positive phase 2 results in CF patients, Insmed's phase 3 registrational study of ARIKACE (CLEAR-108) in Europe and Canada has completed enrollment, and the Company expects top-line clinical results in mid-2013. Insmed's U.S. phase 2 clinical trial in NTM (TARGET-NTM) is well under way with clinical results expected in late 2013.
