"On behalf of the Board and the Company, I would also like to thank Tim Whitten for his unwavering leadership and considerable contributions as CEO over the past six years.

"Our late-stage clinical trials, including our pivotal phase 3 trial in CF patients, are enrolling patients quickly, and we believe this speaks to the need for and interest in ARIKACE. We believe this novel therapy has the potential to improve the lives of patients who battle CF-related Pseudomonas lung infections and non-TB mycobacteria lung infections, both high-growth orphan disease populations. Our focus in the near term will be to prepare the Company for commercialization of ARIKACE in Europe and the U.S. as quickly as possible for the benefit of both patients and Insmed shareholders." 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 novel, targeted inhalation therapies in orphan patient populations with critical unmet needs in high-growth markets. 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 lung infections and patients with nontuberculous mycobacteria lung infections (NTM). Following strong phase 2 results in CF patients, Insmed's CLEAR-108 phase 3 registrational study of ARIKACE in Europe and Canada is well underway, as is the U.S. Phase 2 trial in NTM (TARGET-NTM). The Company expects to report clinical results from both the CLEAR-108 and TARGET-NTM studies in 2013 and currently is preparing for regulatory filings and commercialization.
