Insmed is a biopharmaceutical company focused on developing and commercializing an inhaled anti-infective to treat patients battling serious lung diseases that are often life-threatening. Our lead product candidate, ARIKACE® or liposomal amikacin for inhalation, is an inhaled antibiotic treatment that delivers a proven and potent anti-infective directly to the site of serious lung infections.

Recent Developments and ARIKACE Clinical Summary

In July 2013, Christine Pellizzari was appointed as our General Counsel and Corporate Secretary. In addition, our Board of Directors determined that Donald J. Hayden, our Chairman since December 2010, was independent and that the designation of Dr. Randall Whitcomb, a director since 2001, as lead independent director was no longer necessary.

In July 2013, we completed an underwritten public offering of 6,900,000 shares of our common stock, which includes the underwriter's exercise in full of its over-allotment option of 900,000 shares, at a price to the public of $10.40 per share. The net proceeds from the sale of the shares, after deducting the underwriter's discount and estimated offering expenses, is expected to be approximately $67.0 million.

In July 2013, we announced top-line results from our Phase 3 registrational clinical trial of ARIKACE in cystic fibrosis ("CF") patients who have lung infections caused by Pseudomonas aeruginosa ("Pa") that was conducted in Europe and Canada. In summary, once-daily ARIKACE achieved its primary endpoint of non-inferiority when compared to twice-daily "TOBI" ("tobramycin inhalation solution") for relative change in FEV1 from baseline to the end of the study.

We are conducting a Phase 2 clinical trial in patients who have lung infections caused by non-tuberculous mycobacteria ("NTM") in the U.S and Canada. We are also conducting a two-year, open-label safety study that is enrolling eligible patients who have completed our Phase 3 registrational clinical trial in CF patients in Europe and Canada. Our primary development focus is to obtain regulatory approval for ARIKACE for these two initial indications and to prepare for commercialization initially in Europe and Canada and then in the United States ("US"). If approved, ARIKACE will be the first once-a-day inhaled antibiotic treatment option available for these CF and NTM indications. Our strategy is to continue to develop ARIKACE for additional indications beyond CF patients with Pa infections and patients with NTM lung infections. The following table summarizes the current status of ARIKACE development.

ARIKACE is considered a new molecular entity (NME) by the FDA primarily due to its proprietary liposomal technology. The key active ingredient, amikacin, is an FDA-approved antibiotic with proven efficacy in the treatment of a broad range of gram-negative infections, including Pa and NTM. ARIKACE is in the aminoglycoside class of antibiotics.

ARIKACE is differentiated from other inhaled antibiotics used to treat serious lung infections by our proprietary advanced liposomal technology, which is designed specifically to enhance the delivery profile, safety and efficacy of pharmaceuticals delivered to the lung via inhalation. We believe ARIKACE provides potential improvements over existing treatments for these indications. In our Phase 3 study in CF patients with Pa lung infections, ARIKACE, administered once-daily demonstrated improvements in patient lung function that were comparable to TOBI ("tobramycin inhalation solution"), administered twice-daily and that remained above baseline at the end of the study.

If approved for CF patients with Pa lung infections, we expect ARIKACE would be the first inhaled antibiotic to be approved for once-daily administration in this indication. If approved for NTM patients, we expect ARIKACE would be the first and only approved treatment for NTM lung infections. ARIKACE has been granted orphan drug designation for CF patients who have Pa lung infections in both the European Union ("EU") and the US, and for NTM patients in the US. We plan to file for orphan drug designation for NTM lung infections in Europe during the second half of 2013. 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."

Corporate History

We were incorporated in the Commonwealth of Virginia on November 29, 1999. On December 1, 2010, we completed a business combination with Transave, Inc. (or "Transave") a privately held, New Jersey-based pharmaceutical company focused on the development of differentiated and innovative inhaled pharmaceuticals for the site-specific treatment of serious lung infections. Our current operations are based on the technology and product candidates historically developed by Transave.

Lead Product Candidate - ARIKACE

Our lead product candidate, ARIKACE or liposomal amikacin for inhalation, is a once-a-day inhaled antibiotic treatment engineered to deliver a proven and potent anti-infective directly to the site of serious lung infections. There are two key components of ARIKACE: the liposomal formulation of the drug and the nebulizer device through which ARIKACE is inhaled through the mouth and into the lung. The nebulizer technology is owned by PARI Pharma GmbH ("PARI"), but through our licensing agreement with PARI, we have exclusive access to this technology, which is specifically developed for the delivery of our liposomal encapsulation of amikacin. Our proprietary liposomal technology and nebulizer are designed specifically for delivery of pharmaceuticals to the lung and provides for potential improvements to existing treatments. We believe that ARIKACE has potential usage for at least two orphan patient populations with high unmet need: CF patients who have Pa lung infections and patients who have NTM lung infections. We estimate the combined global market potential for these two orphan indications to be approximately $1 billion.

ARIKACE has the potential to be differentiated from other marketed drugs for the treatment of chronic lung infections by improving efficacy, safety and patient convenience. We believe efficacy may be improved for the treatment of certain lung infections due to the ability of ARIKACE to deliver high, sustained levels of amikacin directly to the lung and to the specific site of the underlying infection. In addition, the inhalation delivery of

ARIKACE may reduce the potential for adverse events such as ototoxicity (hearing loss, ringing in the ears and/or loss of balance) and nephrotoxicity (toxicity to the kidneys), as compared with intravenous (IV) administration of amikacin. If approved, we expect that ARIKACE will be administered once daily for approximately 13 minutes via inhalation using the eFlow® Nebulizer System, which has been optimized specifically for ARIKACE by PARI. We believe that this nebulizer system will reduce treatment time or dosing frequency, as compared with the currently marketed inhaled antibiotics, which require dosing two to three times daily with treatment times ranging from approximately 10 to 40 minutes per day. By easing the patient's treatment burden we believe that ARIKACE can potentially improve patient compliance, which we believe may in turn lead to a reduction in the development of antibiotic resistance and, ultimately, lead to clinical benefit.

We believe that ARIKACE may provide: (1) improved efficacy resulting from sustained deposition of drug in the lung and improved ability to reach the site of infection (for CF Pa infections, this means penetration of biofilm and facilitated drug release by factors that are secreted by the bacteria, and for NTM, this means enhanced uptake into macrophages, where NTM often grows);
(2) decreased adverse events and improved tolerability as compared with amikacin delivered intravenously; and (3) reduced dosing frequency or treatment time as compared to existing products.

ARIKACE for CF Patients with Pseudomonas aeruginosa ("Pa") Lung Infections


CF is an inherited chronic disease that affects the lungs and digestive system and is often diagnosed before the age of two. CF occurs primarily in individuals of central and western European origin. CF affects roughly 70,000 children and adults worldwide, including 30,000 children and adults in the US (Cystic Fibrosis Foundation Patient Registry, 2011) and 35,000 patients in Europe (Hoiby, BMC Medicine, 2011, 9:32). There is no cure for CF.

Despite extensive treatment with multiple antibiotics, improved nutrition, and other treatments, the life expectancy of a CF patient is only about 37 years (Cystic Fibrosis Foundation Patient Registry, 2011). Median predicted age of survival is calculated using life table analysis (as calculated by actuaries) given the ages of the patients in the registry and the distribution of deaths. Using this calculation, half of the people in the patient registry are expected to live beyond the median predicted survival age, and half are expected to live less than the median predicted survival age.

Among other issues, in CF patients a defective gene and its protein product cause the body to produce unusually thick, sticky mucus that clogs the lungs. This creates an ideal environment for various pathogens, such as Pa, to colonize and lead to chronic infection of the lung, inflammation and progressive loss of lung function. In fact, chronic bronchial infections with Pa are a major cause of morbidity and mortality among patients with CF. Once a CF patient acquires a Pa infection, it is difficult to eradicate. The current, best available treatment is chronic administration of antibiotics to suppress the bacteria, reduce inflammation and preserve lung function for as long as possible. The rate of infection with Pa in CF patients increases with age. It is estimated that 70% of adult CF patients have chronic infection due to Pa (CFF Patient Registry, 2011). A study reported in the Journal of Cystic Fibrosis (Liou, 2010) found that deterioration in lung function of CF patients is the main cause of death and that, despite best efforts, lung function declines by 1% to 3% annually.

Current Clinical Program

We recently completed a registrational Phase 3 clinical trial of ARIKACE for CF patients with Pa lung infections in Europe and Canada. The Phase 3 trial was a randomized, open label, multi-center study designed to access the comparative safety and efficacy of once-daily ARIKACE for approximately 13 minutes via the eFlow Nebulizer System and twice-daily TOBI (tobramycin inhalation solution) for approximately 15 minutes per treatment via the PARI LC Plus Nebulizer System for a daily total of approximately 30 minutes per day in CF patients with Pa. A total of 302 adult and pediatric CF patients with chronic Pa were randomized to receive 28-days of ARIKACE treatment or TOBI delivered twice-daily via the PARI LC Plus® Nebulizer System over a 24-week treatment period. The primary endpoint of the study was relative change in forced expiratory volume in one second ("FEV1") measured after three treatment cycles, with each cycle consisting of 28 days "on" treatment and 28 days "off" treatment. The study was designed to demonstrate non-inferiority to TOBI at a 5% non-inferiority margin

Table of Contents

with 80% power agreed upon by us and the European Medicines Agency (EMA). Secondary endpoints measured were relative changes in FEV1 at other time points, time to and number of pulmonary exacerbations, time to antibiotic rescue treatment, change in density of Pa in sputum, respiratory hospitalizations and changes in Patient Reported Outcomes assessing Quality of Life. Top-line results from this study indicated:

† ARIKACE achieved its primary endpoint of non-inferiority to TOBI for relative change in FEV1 from baseline to the end of the study;

† Overall, secondary endpoints, as summarized above, showed comparability of once-daily ARIKACE compared with twice-daily TOBI; and

† The safety profile of ARIKACE was comparable to TOBI during all three treatment cycles, 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.

We are conducting a two-year, open label safety study that is enrolling eligible patients that completed our registrational Phase 3 clinical study of ARIKACE for CF patients with Pa lung infections in Europe and Canada. Approximately 75% of the eligible patients from the registrational Phase 3 clinical study have consented to participate in the safety study. The patients in this study will receive ARIKACE for up to a two year period, using the same cycles of a 28 day on-treatment period and a 28 day off-treatment period. We expect to use interim data from this study as part of our regulatory filings with the EMA and Health Canada, which we expect to submit during the first half of 2014, and we expect to complete this study in mid-2015.

ARIKACE has been granted orphan drug status in the US and Europe for the treatment of Pa lung infections.

Strategy for Commercialization

We currently plan to retain marketing rights for ARIKACE in certain countries in Europe, and in Canada and the US. We believe ARIKACE will require a limited commercial infrastructure in these regions because of the small focused nature of the potential physician prescribing population for CF patients. We may license ARIKACE for certain indications in certain countries in Europe, as well as outside of Europe, and in Canada and the US. In 2013, we commenced preparations for the potential commercialization of ARIKACE in Europe and Canada, including hiring Matt Pauls, our chief commercial officer. We plan to fill several other new positions to support our sales and marketing efforts.

ARIKACE for Patients with NTM Lung Infections


Non-tuberculous mycobacteria, or NTM, are organisms common in soil and water that have been associated with lung disease in select patient groups. NTM have characteristics that are similar to tuberculosis, or TB, but NTM are not contagious. Many people have NTM in their bodies, but NTM do not normally lead to an infection, perhaps because the body's immune system successfully overcomes the threat of infection. It is not completely understood why certain individuals are susceptible to NTM infections. However, the patients who become infected with NTM often are immune-compromised or have structural damage in their lungs at the time of the infection.

NTM are organisms that invade and multiply chiefly within macrophages. They are characteristically resistant to most antibiotics. NTM lung infections are chronic, debilitating and progressive and often require lengthy, repeat hospitalizations. Signs and symptoms of NTM pulmonary disease are variable and nonspecific. They include chronic cough, sputum production and fatigue. Less commonly, malaise, dyspnea, fever, hemoptysis, and weight loss also can occur, usually with advanced NTM pulmonary disease. Evaluation is often complicated by the symptoms caused by co-existing lung diseases. According to a study published in the American Journal of Respiratory and Critical Care Medicine, these conditions include chronic obstructive airway disease

associated with smoking, bronchiectasis, previous mycobacterial diseases, CF and pneumoconiosis (Olivier et al. 2003).

Current Clinical Program

We are currently conducting a Phase 2 clinical trial in the US and Canada for ARIKACE in adult patients with NTM lung infections. We began enrolling patients in June 2012. The Phase 2 clinical trial is a randomized, placebo-controlled study of approximately 100 adult patients with recalcitrant NTM lung infections. Of the targeted enrollment of 100 patients, 81 patients have been enrolled in this study as of June 30, 2013. There are two parts to the study: a randomized portion and an open-label portion.

In the randomized portion of the study, patients are screened initially to include in the study those who have NTM lung infections with persistent sputum culture for MAC or M. abscessus while on American Thoracic Society and Infectious Disease Society of America (ATS/IDSA)-guidelines-based treatment regimen for at least six months prior to screening. Patients who are NTM culture positive and meet the eligibility criteria to enroll in the study will receive, in addition to their ongoing antibiotic treatment regimen, either ARIKACE or a placebo both delivered once daily for approximately 13 minutes via an optimized, investigational eFlow Nebulizer System. The primary efficacy endpoint for this study is the change in mycobacterial density from baseline to the end of 84 days of treatment. At a public workshop discussion in September 2012, the FDA agreed that the microbiological end-point is an appropriate primary end-point for NTM lung disease. The study will also measure secondary endpoints, including the proportion of patients with culture conversion to negative, the time to "rescue" anti-mycobacterial drugs, the change from baseline in six-minute walk distance and oxygen saturation, the change from baseline in patient reported outcomes, and evaluation of safety and tolerability.

At the conclusion of the randomized portion of the study, eligible patients will receive ARIKACE once daily for an additional 84 days during the open-label portion of the study, primarily to measure longer-term safety and efficacy. We previously agreed with the FDA on this clinical trial design.

On June 28, 2013, the FDA designated ARIKACE as a Qualified Infectious Disease Product ("QIDP") for the treatment of NTM. The QIDP designation for ARIKACE will enable us 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 exclusivity extension under the "The Drug Price Competition and Patent Term Restoration Act, also known as the "Hatch-Waxman" Act. These incentives are provided under the "Generating Antibiotic Incentives Now" Act (the "GAIN" Act), which was signed into law in July 2012.

Additionally, on June 28, 2013, the FDA granted Fast Track designation to ARIKACE for the treatment of NTM. The Fast Track designation is intended to . . .
