BRIDGEWATER, N.J., May 16, 2018 (GLOBE NEWSWIRE) — Insmed Incorporated (Nasdaq:INSM), a global biopharmaceutical company focused on the unmet needs of patients with rare diseases, announced today that the U.S. Food and Drug Administration (FDA) has notified the company that the New Drug Application (NDA) for ALIS (Amikacin Liposome Inhalation Suspension) for adult patients with nontuberculous mycobacterial (NTM) lung disease caused by Mycobacterium avium complex (MAC) has been accepted and will be considered filed on May 27, 2018. The FDA has completed the filing review and determined that the application is sufficiently complete to permit a substantive review. The FDA granted Insmed’s request for Priority Review and has set an action date of September 28, 2018 under the Prescription Drug User Fee Act (PDUFA).
“We are pleased that the FDA has accepted our NDA with Priority Review, which underscores the urgent need for therapies which address NTM lung disease caused by MAC,” said Will Lewis, President and Chief Executive Officer of Insmed. “ALIS has the potential to be the first approved inhaled therapy for the treatment of this serious and debilitating lung infection in the United States, and we look forward to working with the Agency through the review process.”
Insmed continues to expect that the FDA will convene an advisory committee meeting to discuss this application.
Priority Review applies to an application for a drug that treats a serious condition and that, if approved, would provide a significant improvement in safety or effectiveness. FDA has previously designated ALIS as an orphan drug, a breakthrough therapy and a Qualified Infectious Disease Product (QIDP) under the Generating Antibiotic Incentives Now (GAIN) Act.
About NTM Lung Disease
NTM lung disease is a rare and serious disorder associated with increased rates of morbidity and mortality. There is an increasing prevalence of lung disease caused by NTM, and Insmed believes it is an emerging public health concern worldwide. Patients with NTM lung disease may experience a multitude of symptoms such as fever, weight loss, cough, lack of appetite, night sweats, blood in the sputum, and fatigue. Patients with NTM lung disease frequently require lengthy hospital stays to manage their condition. Insmed is not aware of any approved inhaled therapies specifically indicated for refractory NTM lung disease caused by MAC in North America, Japan or Europe. Current guideline-based approaches involve use of multi-drug regimens not approved for the treatment of NTM lung disease, and treatment can be as long as two years or more.
The prevalence of human disease attributable to NTM has increased over the past two decades. In a decade long study (1997 to 2007), researchers found that the prevalence of NTM lung disease in the U.S. was increasing at approximately 8% per year and that NTM patients on Medicare over the age of 65 were 40% more likely to die over the period of the study than those who did not have the disease. In the U.S., Insmed estimates there will be between 75,000 and 105,000 patients with diagnosed NTM lung disease in 2018, of which the Company expects 40,000 to 50,000 will be treated for NTM lung disease caused by MAC. Insmed expects that between 10,000 and 15,000 of these patients will be refractory to treatment. In Japan, Insmed estimates there will be between 125,000 and 145,000 patients with diagnosed NTM lung disease in 2018, with approximately 60,000 to 70,000 of those patients being treated for NTM lung disease caused by MAC and 15,000 to 18,000 of these treated patients being refractory to treatment. Insmed also estimates there will be approximately 14,000 patients with diagnosed NTM lung disease in the EU5 (comprised of France, Germany, Italy, Spain and the United Kingdom) in 2018, of which the Company estimates approximately 4,400 will be treated for NTM lung disease caused by MAC and approximately 1,400 of these treated patients will be refractory to treatment.
ALIS is a novel, inhaled, once-daily formulation of amikacin that is in late-stage clinical development for adult patients with treatment-refractory NTM lung disease caused by MAC. Amikacin solution for parenteral administration is an established drug that has activity against a variety of NTM; however, its use is limited by the need to administer it intravenously and by toxicity to hearing, balance, and kidney function. Insmed’s advanced pulmonary liposome technology uses charge neutral liposomes to deliver amikacin directly to the lung where it is taken up by the lung macrophages where the NTM infection resides. This prolongs the release of amikacin in the lungs while minimizing systemic exposure thereby offering the potential for decreased systemic toxicities. ALIS’s ability to deliver high levels of amikacin directly to the lung distinguishes it from intravenous amikacin. ALIS is administered once daily using an optimized, investigational eFlow® Nebulizer System manufactured by PARI Pharma GmbH (PARI), a portable aerosol delivery system.
Insmed Incorporated is a global biopharmaceutical company focused on the unmet needs of patients with rare diseases. The Company’s lead product candidate is ALIS, which is in late-state development for adult patients with treatment refractory NTM lung disease caused by MAC, which is a rare and often chronic infection that is capable of causing irreversible lung damage and can be fatal. Insmed’s earlier-stage clinical pipeline includes INS1007, a novel oral reversible inhibitor of dipeptidyl peptidase 1 with therapeutic potential in non-cystic fibrosis bronchiectasis and other inflammatory diseases, and INS1009, an inhaled nanoparticle formulation of a treprostinil prodrug that may offer a differentiated product profile for rare pulmonary disorders, including pulmonary arterial hypertension.
