European Commission Grants Marketing Authorization for ARIKAYCE® Liposomal 590 mg Nebuliser Dispersion for the Treatment of NTM Lung Infections Caused by MAC in Adult Non-CF Patients with Limited Treatment Options

BRIDGEWATER, N.J., Oct. 28, 2020 /PRNewswire/ — Insmed Incorporated (Nasdaq:INSM), a global biopharmaceutical company on a mission to transform the lives of patients with serious and rare diseases, today announced that the European Commission (EC) has granted marketing authorization for ARIKAYCE^® Liposomal 590 mg Nebuliser Dispersion ("ARIKAYCE") for the treatment of nontuberculous mycobacterial (NTM) lung infections caused by Mycobacterium avium complex (MAC) in adults with limited treatment options who do not have cystic fibrosis. Consideration should be given to official guidance on the appropriate use of antibacterial agents.

"We are thrilled that for the first time, non-CF patients with NTM lung infections caused by MAC in the European Union (EU) have an approved therapy to help manage this difficult-to-treat condition, providing a new approach for those who have suffered with few, or no, treatment options," said Will Lewis, Chair and Chief Executive Officer of Insmed. "Today's approval underscores our commitment to serving the MAC lung disease community around the world, and we look forward to bringing ARIKAYCE to appropriate patients in the EU."

The EC approval of ARIKAYCE is based on results from the randomized, open-label, global Phase 3 CONVERT study, which demonstrated that once-daily ARIKAYCE, when combined with multi-drug regimen (MDR), improved sputum culture conversion rates in patients with refractory NTM lung disease caused by MAC compared to MDR therapy alone. The most common side effects with ARIKAYCE affecting the respiratory system are dysphonia, cough, dyspnea, and hemoptysis.

"Today's approval marks a significant milestone in advancing care for patients with MAC lung disease in the EU," said Professor Michael Loebinger, Respiratory Consultant at Royal Brompton Hospital, London, Professor of Practice (Respiratory Medicine) at Imperial College, London, and an investigator in the CONVERT study. "Currently, many patients fail to respond to the standard treatment regimen and continue to suffer from the debilitating effects of this rare and serious disease. Results from the landmark CONVERT study show that adding ARIKAYCE has the potential to help patients who were refractory to standard treatment achieve culture conversion—a critical outcome."

The EC approval follows a positive opinion from the Committee for Medicinal Products for Human Use of the European Medicines Agency (EMA) on July 24, 2020. In addition, the Committee for Orphan Medicinal Products of the EMA has adopted a positive opinion recommending that ARIKAYCE maintain Orphan Drug Designation in the EU for the treatment of NTM lung disease, which was originally granted to Insmed in 2014.

Insmed plans to launch ARIKAYCE first in Germany, followed by the United Kingdom (UK) and other EU markets, subject to local reimbursement processes. As part of Insmed's comprehensive approach to patient support, the Company has established country-specific programs to provide patients with direct and ongoing support and information.

"The treatment of MAC lung disease is challenging, with a significant need for new therapies that improve upon the current standard of care and offer options to patients who previously have not been treated successfully," noted Marc Lipman, Professor of Respiratory Medicine at University College, London, and one of the founding Trustees of NTM Patient Care UK.

In the United States, ARIKAYCE (under the generic name amikacin liposome inhalation suspension), is the first and only approved treatment for MAC lung disease as part of a combination antibacterial drug regimen for adult patients with limited or no alternative treatment options. Insmed has submitted a new drug application for ARIKAYCE in Japan for the treatment of patients with NTM lung disease caused by MAC who did not sufficiently respond to prior treatment.

About MAC Lung Disease

Mycobacterium avium complex (MAC) lung disease is a rare and serious disorder that can significantly increase morbidity and mortality. Patients with MAC lung disease can experience a range of symptoms that often worsen over time, including chronic cough, dyspnea, fatigue, fever, weight loss, and chest pain. In some cases, MAC lung disease can cause severe, even permanent damage to the lungs, and can be fatal. MAC lung disease is an emerging public health concern worldwide with significant unmet need.

About ARIKAYCE

ARIKAYCE is approved in the United States as ARIKAYCE^® (amikacin liposome inhalation suspension) and in the EU as ARIKAYCE^® Liposomal 590 mg Nebuliser Dispersion. Current international treatment guidelines recommend the use of ARIKAYCE for appropriate patients. ARIKAYCE is a novel, inhaled, once-daily formulation of amikacin, an established antibiotic that was historically administered intravenously and associated with severe toxicity to hearing, balance, and kidney function. Insmed's proprietary PULMOVANCE™ liposomal technology enables the delivery of amikacin directly to the lungs, where liposomal amikacin is taken up by lung macrophages where the infection resides, while limiting systemic exposure. ARIKAYCE is administered once daily using the Lamira^® Nebulizer System manufactured by PARI Pharma GmbH (PARI).

About PARI Pharma and the Lamira^® Nebulizer System

ARIKAYCE is delivered by a novel inhalation device, the Lamira^® Nebulizer System, developed by PARI. Lamira^® is a quiet, portable nebulizer that enables efficient aerosolization of ARIKAYCE via a vibrating, perforated membrane. Based on PARI's 100-year history working with aerosols, PARI is dedicated to advancing inhalation therapies by developing innovative delivery platforms and new pharmaceutical formulations that work together to improve patient care.  

IMPORTANT SAFETY INFORMATION FOR ARIKAYCE IN THE U.S.

Hypersensitivity Pneumonitis has been reported with the use of ARIKAYCE in the clinical trials. Hypersensitivity pneumonitis (reported as allergic alveolitis, pneumonitis, interstitial lung disease, allergic reaction to ARIKAYCE) was reported at a higher frequency in patients treated with ARIKAYCE plus background regimen (3.1%) compared to patients treated with a background regimen alone (0%). Most patients with hypersensitivity pneumonitis discontinued treatment with ARIKAYCE and received treatment with corticosteroids. If hypersensitivity pneumonitis occurs, discontinue ARIKAYCE and manage patients as medically appropriate.

Hemoptysis has been reported with the use of ARIKAYCE in the clinical trials. Hemoptysis was reported at a higher frequency in patients treated with ARIKAYCE plus background regimen (17.9%) compared to patients treated with a background regimen alone (12.5%). If hemoptysis occurs, manage patients as medically appropriate.

Bronchospasm has been reported with the use of ARIKAYCE in the clinical trials. Bronchospasm (reported as asthma, bronchial hyperreactivity, bronchospasm, dyspnea, dyspnea exertional, prolonged expiration, throat tightness, wheezing) was reported at a higher frequency in patients treated with ARIKAYCE plus background regimen (28.7%) compared to patients treated with a background regimen alone (10.7%). If bronchospasm occurs during the use of ARIKAYCE, treat patients as medically appropriate.

Exacerbations of underlying pulmonary disease has been reported with the use of ARIKAYCE in the clinical trials. Exacerbations of underlying pulmonary disease (reported as chronic obstructive pulmonary disease (COPD), infective exacerbation of COPD, infective exacerbation of bronchiectasis) have been reported at a higher frequency in patients treated with ARIKAYCE plus background regimen (14.8%) compared to patients treated with background regimen alone (9.8%). If exacerbations of underlying pulmonary disease occur during the use of ARIKAYCE, treat patients as medically appropriate.

Anaphylaxis and Hypersensitivity Reactions: Serious and potentially life-threatening hypersensitivity reactions, including anaphylaxis, have been reported in patients taking ARIKAYCE. Signs and symptoms include acute onset of skin and mucosal tissue hypersensitivity reactions (hives, itching, flushing, swollen lips/tongue/uvula), respiratory difficulty (shortness of breath, wheezing, stridor, cough), gastrointestinal symptoms (nausea, vomiting, diarrhea, crampy abdominal pain), and cardiovascular signs and symptoms of anaphylaxis (tachycardia, low blood pressure, syncope, incontinence, dizziness). Before therapy with ARIKAYCE is instituted, evaluate for previous hypersensitivity reactions to aminoglycosides. If anaphylaxis or a hypersensitivity reaction occurs, discontinue ARIKAYCE and institute appropriate supportive measures.

Ototoxicity has been reported with the use of ARIKAYCE in the clinical trials. Ototoxicity (including deafness, dizziness, presyncope, tinnitus, and vertigo) were reported with a higher frequency in patients treated with ARIKAYCE plus background regimen (17%) compared to patients treated with background regimen alone (9.8%). This was primarily driven by tinnitus (7.6% in ARIKAYCE plus background regimen vs 0.9% in the background regimen alone arm) and dizziness (6.3% in ARIKAYCE plus background regimen vs 2.7% in the background regimen alone arm). Closely monitor patients with known or suspected auditory or vestibular dysfunction during treatment with ARIKAYCE. If ototoxicity occurs, manage patients as medically appropriate, including potentially discontinuing ARIKAYCE.

Nephrotoxicity was observed during the clinical trials of ARIKAYCE in patients with MAC lung disease but not at a higher frequency than background regimen alone. Nephrotoxicity has been associated with the aminoglycosides. Close monitoring of patients with known or suspected renal dysfunction may be needed when prescribing ARIKAYCE.

Neuromuscular Blockade: Patients with neuromuscular disorders were not enrolled in ARIKAYCE clinical trials. Patients with known or suspected neuromuscular disorders, such as myasthenia gravis, should be closely monitored since aminoglycosides may aggravate muscle weakness by blocking the release of acetylcholine at neuromuscular junctions.

Embryo-Fetal Toxicity: Aminoglycosides can cause fetal harm when administered to a pregnant woman. Aminoglycosides, including ARIKAYCE, may be associated with total, irreversible, bilateral congenital deafness in pediatric patients exposed in utero. Patients who use ARIKAYCE during pregnancy, or become pregnant while taking ARIKAYCE should be apprised of the potential hazard to the fetus.

Contraindications: ARIKAYCE is contraindicated in patients with known hypersensitivity to any aminoglycoside.

Most Common Adverse Reactions: The most common adverse reactions in Trial 1 at an incidence ≥5% for patients using ARIKAYCE plus background regimen compared to patients treated with background regimen alone were dysphonia (47% vs 1%), cough (39% vs 17%), bronchospasm (29% vs 11%), hemoptysis (18% vs 13%), ototoxicity (17% vs 10%), upper airway irritation (17% vs 2%), musculoskeletal pain (17% vs 8%), fatigue and asthenia (16% vs 10%), exacerbation of underlying pulmonary disease (15% vs 10%), diarrhea (13% vs 5%), nausea (12% vs 4%), pneumonia (10% vs 8%), headache (10% vs 5%), pyrexia (7% vs 5%), vomiting (7% vs 4%), rash (6% vs 2%), decreased weight (6% vs 1%), change in sputum (5% vs 1%), and chest discomfort (5% vs 3%).

Drug Interactions: Avoid concomitant use of ARIKAYCE with medications associated with neurotoxicity, nephrotoxicity, and ototoxicity. Some diuretics can enhance aminoglycoside toxicity by altering aminoglycoside concentrations in serum and tissue. Avoid concomitant use of ARIKAYCE with ethacrynic acid, furosemide, urea, or intravenous mannitol.

Overdosage: Adverse reactions specifically associated with overdose of ARIKAYCE have not been identified. Acute toxicity should be treated with immediate withdrawal of ARIKAYCE, and baseline tests of renal function should be undertaken. Hemodialysis may be helpful in removing amikacin from the body. In all cases of suspected overdosage, physicians should contact the Regional Poison Control Center for information about effective treatment.

U.S. INDICATION

LIMITED POPULATION: ARIKAYCE^® is indicated in adults, who have limited or no alternative treatment options, for the treatment of Mycobacterium avium complex (MAC) lung disease as part of a combination antibacterial drug regimen in patients who do not achieve negative sputum cultures after a minimum of 6 consecutive months of a multidrug background regimen therapy. As only limited clinical safety and effectiveness data for ARIKAYCE are currently available, reserve ARIKAYCE for use in adults who have limited or no alternative treatment options. This drug is indicated for use in a limited and specific population of patients.

This indication is approved under accelerated approval based on achieving sputum culture conversion (defined as 3 consecutive negative monthly sputum cultures) by Month 6. Clinical benefit has not yet been established. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.

Limitation of Use: ARIKAYCE has only been studied in patients with refractory MAC lung disease defined as patients who did not achieve negative sputum cultures after a minimum of 6 consecutive months of a multidrug background regimen therapy.
