SafetyDuring all three treatment cycles, the safety profile of ARIKACE was comparable to TOBI, with adverse events consistent with those seen in similar studies and expected in a population of CF patients receiving inhaled antibiotics. There was no difference between arms in the reporting of serious adverse events and there were no unexpected adverse events. "The Phase 3 study of ARIKACE achieved its primary endpoint and demonstrated that ARIKACE is an effective inhaled antibiotic. These results are consistent with our earlier studies of ARIKACE and we believe further strengthen the clinical data packages Insmed is developing for submission to the EMA and Health Canada for ARIKACE in the treatment of CF," said Renu Gupta, MD, FAAP, Executive Vice President Development and Chief Medical Officer of Insmed. “If approved, we believe ARIKACE, with its once-daily administration, represents a novel alternative for clinicians treating CF patients with chronic lung infection caused by Pseudomonas aeruginosa." “The study achieved its primary endpoint and suggests that once-daily ARIKACE treatment was comparable to twice-daily TOBI treatment, the current gold standard of care for cystic fibrosis patients with Pseudomonas aeruginosa lung infections,” stated Felix Ratjen, MD, PhD, FRCPC Head, Division of Respiratory Medicine, Sellers Chair of Cystic Fibrosis, Professor, University of Toronto Hospital for Sick Children and Co-Chair of the study Steering Committee. “These results provide hope that an inhaled aminoglycoside that requires only once-daily dosing may be added to the toolbox of available therapies for physicians to treat cystic fibrosis patients who suffer from chronic Pseudomonas aeruginosa lung infections.” “This early review of data is encouraging. ARIKACE has the potential to be the first once-daily treatment, as compared with the current treatment regimens that require multiple dosing each day. Once-daily treatment may significantly enhance patient convenience and compliance,” stated Bonnie Ramsey, MD, Seattle Children’s Hospital, Director, Cystic Fibrosis Therapeutics, Development Network Coordinating Center and Chair of the study Steering Committee.
“Cystic fibrosis patients chronically infected with Pseudomonas aeruginosa are among the most heavily burdened patients when it comes to the number, frequency and types of treatments they need to take on a daily basis. The data from this study suggest that once-daily treatment with ARIKACE may provide a safe, effective and more convenient alternative to twice-daily TOBI treatment,” stated Diana Bilton, MD, Director of Adult CF Centre at the Royal Brompton Hospital in London, and the Principal Investigator of the study. “The hope of a once-daily treatment offers encouragement to cystic fibrosis patients suffering with Pseudomonas aeruginosa lung infections.”“We are very pleased with the results ARIKACE achieved in our Phase 3 trial and our attention now turns to preparing for regulatory filings with the EMA and Health Canada, which we expect to make during the first half of 2014,” said Will Lewis, President and Chief Executive Officer of Insmed. “We appreciate the support of the Cystic Fibrosis Foundation and the European Cystic Fibrosis Society, and thank our principal investigators and patients for their commitment to this study. We look forward to the opportunity to present the complete data set at an upcoming medical conference and to having it published in a peer-reviewed journal. More importantly, if approved by the EMA and Health Canada, we look forward to bringing ARIKACE to market in order to benefit the thousands of CF patients in need of an effective and convenient treatment for these chronic and often life-threatening Pseudomonas aeruginosa lung infections,” he added. Two-Year Extension Study Eligible patients from this Phase 3 trial were given the option to participate in a two-year, open-label safety study. Approximately 75% of eligible patients have consented to participate in this study. The Company expects to use data from this study as part of the regulatory submissions to the European and Canadian authorities.
ARIKACE for the Treatment of NTMInsmed is currently enrolling patients in the U.S. and Canada in a Phase 2 clinical trial of LAI to treat NTM lung infections. Of the targeted enrollment of 100 patients, 81 patients have been enrolled in this study to date. The second regularly scheduled Data Safety Monitoring Board (DSMB) meeting was held on June 28th, 2013 and the DSMB again recommended proceeding with the study without modifications. "NTM lung infection is a disease that is being recognized and diagnosed with increasing frequency in the U.S. and worldwide. The risk for NTM lung disease is especially high in women as they age beyond the sixth decade of life. Pulmonary and Infectious Disease physicians are seeing these patients in ever growing numbers. While therapy can be reasonably effective for some patients, it routinely entails multiple, potentially toxic and expensive medications that must be given over long periods of time. Sadly, for many other patients, current therapies are inadequate with few alternative treatment strategies available,” said Dr. David Griffith, Professor of Medicine, W.A and E. B. Moncrief Distinguished Professor The University of Texas Health Sciences Center and a co-Principal Investigator on the U.S. NTM study. “Research in the area of NTM lung disease has been woefully underfunded with no major therapeutic advances in the last 20 years. The availability of a once-a-day product that can help reduce bacterial density in these patients would represent a major step forward in the treatment of this disease," added Dr. Griffith. On June 28, 2013, ARIKACE was granted QIDP designation and Fast Track designation by the FDA for the “treatment of Non-Tuberculous Mycobacterial lung infections.” The QIDP designation for ARIKACE will enable Insmed to benefit from certain incentives for the development of new antibiotics, including potentially more frequent and ongoing dialogue with FDA, priority review, and if ARIKACE is ultimately approved by the FDA, a five-year extension of Hatch-Waxman exclusivity. These incentives are provided under the Generating Antibiotic Incentives Now Act (GAIN Act), which was signed into law in July 2012 as part of the FDA Safety and Innovation Act, the fifth authorization of the Prescription Drug User Fee Act.
The Fast Track designation is intended to expedite the review of new drugs that have the potential to serve unmet medical needs in serious or life-threatening conditions. Under this designation Insmed will have the opportunity to submit completed sections of any future NTM New Drug Application (NDA) for rolling review by FDA, rather than waiting until every section of the application is complete before the entire application can be reviewed. FDA’s review clock for the NDA will begin once the final section is submitted.“QIDP designation for ARIKACE underscores the importance the FDA places on helping to advance critically needed antibiotics for serious infections such as NTM,” stated Mr. Lewis. “We believe this is an acknowledgment by the FDA of the potentially important role that ARIKACE may play in the treatment of NTM. QIDP and Fast Track designations may help us bring ARIKACE to patients who face these serious and life-threatening lung infections more quickly. We also believe that QIDP status complements the intellectual property protection provided by our underlying patents.” Pursuant to QIDP status, the Company expects to continue its dialogue with the FDA regarding the regulatory pathway for registration and approval of ARIKACE to treat NTM. Insmed expects to complete the Phase 2 data review and related dialogue with the FDA by the end of the first quarter of 2014.

About Cystic Fibrosis According to the Cystic Fibrosis Foundation, CF is an inherited chronic disease that affects the lungs and digestive system of about 30,000 children and adults in the U.S. (70,000 worldwide). A defective gene and its protein product cause the body to produce unusually thick, sticky mucus that clogs the lungs and leads to life-threatening lung infections, and obstructs the pancreas and stops natural enzymes from helping the body break down and absorb food.
About Non-Tuberculous MycobacteriaNTM infections are acquired directly from the environment, where they are often present in soil and various water sources. The prevalence of NTM disease is reported to be increasing, and according to reports from the American Thoracic Society, is believed to be likely greater than that of tuberculosis in the United States. According to the National Center for Biotechnology Information, epidemiological studies show that presence of NTM infection is increasing in developing countries, perhaps because of the implementation of tap water. Women with characteristic phenotype are believed to be at higher risk of acquiring NTM infection along with patients with defects on cystic fibrosis transmembrane conductance regulators. About ARIKACE ® ARIKACE is a form of the antibiotic amikacin, which is enclosed in nanocapsules of lipid called liposomes. This advanced pulmonary liposome technology prolongs the release of amikacin in the lungs while minimizing systemic exposure. The treatment uses biocompatible lipids endogenous to the lung that are formulated into small (0.3 micron), charge-neutral liposomes. ARIKACE is administered once-daily using an optimized, investigational eFlow® Nebulizer System manufactured by PARI Pharma GmbH, a novel, highly efficient and portable aerosol delivery system. ARIKACE has been granted orphan drug designation in the U.S. by the FDA for the treatment of Pseudomonas infections in patients with CF and for the treatment of NTM lung infections. ARIKACE has also received orphan drug designation in Europe by the EMA for the treatment of Pseudomonas infections in patients with CF. About eFlow® Technology and PARI Pharma ARIKACE is delivered by an investigational eFlow® Nebulizer System developed by PARI Pharma and optimized specifically for ARIKACE. The optimized device uses eFlow Technology to enable highly efficient aerosolization of medication including liposomal formulations via a vibrating, perforated membrane that includes thousands of laser-drilled holes. Compared with other nebulization technologies, eFlow Technology produces aerosols with a very high density of active drug, a precisely defined droplet size and a high proportion of respirable droplets delivered in the shortest possible period of time. eFlow Technology is not an ultrasonic nebulizer technology and is not a general purpose electronic aerosol generator nebulizer technology. Combined with its quiet mode of operation, small size, light weight and battery use, eFlow Technology reduces the burden of taking daily, inhaled treatments. PARI Pharma focuses on the development of aerosol delivery devices and inhalation drug development to advance aerosol therapies where drug and device can be optimized together.
