Insmed Announces FDA Approval of ARIKAYCE® (amikacin liposome inhalation suspension), the First and Only Therapy Specifically Indicated for the Treatment of Mycobacterium Avium Complex (MAC) Lung Disease in Adult Patients with Limited or No Alternative Treatment Options

BRIDGEWATER, N.J., Sept. 28, 2018 (GLOBE NEWSWIRE) -- Insmed Incorporated (Nasdaq:INSM), a global biopharmaceutical company focused on the unmet needs of patients with rare diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted accelerated approval of ARIKAYCE® (amikacin liposome inhalation suspension) for the treatment of Mycobacterium avium complex (MAC) lung disease as part of a combination antibacterial drug regimen for adult patients who have limited or no alternative treatment options. ARIKAYCE is the first and only therapy approved in the U.S. specifically for patients with MAC lung disease, a chronic and debilitating condition that can significantly increase patient morbidity and mortality.

ARIKAYCE is the first product approved via the Limited Population Pathway for Antibacterial and Antifungal Drugs (LPAD). LPAD, which was enacted as part of the 21st Century Cures Act, serves to advance the development of new antibacterial drugs to treat serious or life-threatening infections in limited populations of patients with unmet needs.

“Today’s approval is a momentous occasion for all of us living with and advocating for people with MAC lung disease,” said Philip Leitman, President of Nontuberculous Mycobacteria Info & Research (NTMir). “ARIKAYCE provides a much-needed treatment for patients with this chronic and life-threatening disease who have not responded to the current standard of care. Many of these patients have been suffering for years and face significant challenges in their day-to-day lives, and we are excited to finally have an approved treatment for them.”

“Patients suffering from MAC lung disease who have not responded to available guideline-based therapies face a restricted quality of life due to this debilitating and progressive illness. As a physician and Principal Investigator in the CONVERT study, I am extremely pleased that there is now a therapy specifically studied in and approved for patients with MAC lung disease who currently have limited or no treatment options,” said David Griffith, M.D., Professor of Medicine, W.A. and E.B. Moncrief Distinguished Professor at The University of Texas Health Science Center. “ARIKAYCE has the potential to address the significant unmet needs in this difficult-to-treat population.”

Physicians can begin prescribing ARIKAYCE immediately and Insmed expects product to be available in select specialty pharmacies in the coming weeks. Insmed is committed to providing access to ARIKAYCE for appropriate patients with MAC lung disease and to supporting these patients throughout their treatment journey. The Company has launched the Arikares Support Program, which provides dedicated coordinators to help patients navigate the reimbursement process and trainers who can familiarize patients with how to use ARIKAYCE. Patients prescribed ARIKAYCE can call 1-833-ARIKARE to enroll in the support program.

“The approval of ARIKAYCE is a significant moment for adult patients suffering from MAC lung disease who have limited or no available treatment options. It also represents an incredible milestone for our company, which has taken this medicine from concept to approval and now will launch the drug across the U.S. Our mission is to address the unmet needs of patients with serious and rare diseases, and we are thrilled to be able to provide the first-ever approved therapy specifically for patients in the U.S. with MAC lung disease,” said Will Lewis, President and Chief Executive Officer of Insmed. “I want to thank the patients and physicians who have made this milestone possible through their participation in the clinical trials, as well as our dedicated Insmed team. We look forward to focusing our efforts on the launch of ARIKAYCE in the U.S.”

The approval of ARIKAYCE under FDA’s LPAD and accelerated approval pathways was based on results from the ongoing Phase 3 CONVERT study, which has demonstrated that ARIKAYCE, when combined with guideline-based therapy (GBT), improved sputum culture conversion rates. The global CONVERT study met its primary endpoint of sputum culture conversion by Month 6 with statistical significance for once-daily ARIKAYCE when added to GBT compared with GBT alone (p<0.0001) in patients with refractory nontuberculous mycobacterial (NTM) lung disease caused by MAC. In the study, the addition of ARIKAYCE to GBT eliminated evidence of NTM lung disease caused by MAC in sputum by Month 6 in 29% of patients, compared to 9% of patients on GBT alone.

Patients who are prescribed ARIKAYCE will be provided with a Medication Guide containing important safety information set forth below, including the boxed warning, as well as full Instructions for Use and a step-by-step guide to using the product. Insmed also will send health care providers a letter describing the scope of the limited population approval and the potential risk of respiratory adverse reactions.

As a condition of accelerated approval, Insmed is collaborating with the FDA on the design of an additional clinical study to support full approval. The study design is currently under discussion with FDA and is proposed to be a randomized, double-blind, placebo-controlled clinical trial to assess and describe the clinical benefit of ARIKAYCE in patients with NTM lung disease caused by MAC. The trial will evaluate the effect of ARIKAYCE on a clinically meaningful endpoint, as compared to an appropriate control, in the intended patient population of patients with MAC infection. Insmed will provide additional updates once the study design has been finalized with FDA. Continued approval of ARIKAYCE will be contingent upon verification and description of clinical benefit in this study.

ARIKAYCE is administered once daily using the Lamira™ Nebulizer System (PARI Pharma GmbH [PARI]).
