We have a tremendous opportunity ahead and are excited to continue progressing toward the vision we set out for this company over a decade ago."

Recent Pillar Highlights

Pillar 1: ARIKAYCE 

• ARIKAYCE global revenue grew 17% in the second quarter of 2024 compared to the second quarter of 2023, reflecting double-digit year-over-year growth in the U.S., Japan, and Europe and all-time revenue highs for each of these three regions.
• The Company met with the U.S. Food and Drug Administration (FDA) in June and aligned on the primary endpoint for the Phase 3 ENCORE study in patients with newly diagnosed or recurrent Mycobacterium avium complex (MAC) lung infection who have not started antibiotics.
• Insmed is targeting enrollment of 400 patients in the ENCORE study and expects to report topline data in the first quarter of 2026.

Pillar 2: Brensocatib 

• Insmed reported positive topline data from the Phase 3 ASPEN study of brensocatib in patients with bronchiectasis in May 2024. The study met its primary endpoint, with both dosage strengths of brensocatib demonstrating statistically significant reductions in the annualized rate of adjudicated pulmonary exacerbations versus placebo. The study also met several prespecified secondary endpoints with statistical significance, including the change from baseline in forced expiratory volume in 1 second (FEV1) for the 25 mg dose.
• Based on these results, the Company plans to file a New Drug Application (NDA) with the FDA for brensocatib in patients with bronchiectasis in the fourth quarter of 2024. Pending regulatory approvals, Insmed anticipates a U.S. launch for brensocatib in mid-2025 and launches in Europe and Japan in the first half of 2026.
• Additional positive results from the ASPEN study were presented in July 2024 at the 7th World Bronchiectasis Conference in Dundee, Scotland, including nominally significant findings for the 25 mg dose from two exploratory endpoints: change in post-bronchodilator forced vital capacity (FVC) and change in average daily bronchiectasis exacerbation and symptom tool (BEST) score, a novel symptom diary.
• Insmed looks forward to presenting additional data from the ASPEN study, including prespecified subpopulation data, at CHEST 2024, taking place October 6-9 in Boston.
• Insmed is advancing launch readiness activities in the U.S. and plans to have 120 new therapeutic specialists hired, trained, and in the field well in advance of launch, focused on bronchiectasis disease state awareness and education while also detailing ARIKAYCE.
• The Company continues to enroll patients in the Phase 2b BiRCh trial of brensocatib in patients with chronic rhinosinusitis without nasal polyps (CRSsNP) and anticipates providing topline data from the study in the second half of 2025.
• The Company anticipates activating the first U.S. sites in its Phase 2 study of brensocatib in patients with hidradenitis suppurativa (HS) by the end of 2024.

Pillar 3: TPIP 

• Insmed reported positive topline safety and tolerability data as well as certain exploratory efficacy endpoints from the Phase 2 study of treprostinil palmitil inhalation powder (TPIP) in patients with pulmonary hypertension associated with interstitial lung disease (PH-ILD) in May 2024.
• The Company continues to anticipate initiating a Phase 3 study of TPIP in patients with PH-ILD in 2025.
• Enrollment remains ongoing in the Phase 2 study of TPIP in patients with pulmonary arterial hypertension (PAH), with more than 75% of the target enrollment currently complete.
• Insmed remains on track to report topline results from the PAH study in the second half of 2025.

Pillar 4: Early-Stage Research

• Insmed's early-stage research efforts include more than 30 identified pre-clinical programs in development, all of which have the potential to become first-in-class or best-in-class therapies.
• The Company continues to anticipate the totality of its early-stage research programs will comprise less than 20% of overall spend.

Corporate Updates

• During the second quarter of 2024, Insmed completed a public offering of 14,514,562 shares of common stock, including 1,893,203 shares issued pursuant to the exercise in full of the underwriters' option to purchase additional shares. The Company's net proceeds from the sale of the shares, after underwriting discounts and other estimated offering-related expenses, were $713.2 million.
• In June 2024, the Company issued a notice of redemption for all $225 million aggregate principal amount of its outstanding 1.75% convertible senior notes due in January 2025, with a redemption date of August 9, 2024. As of August 7, 2024, 99.9% of the outstanding notes, or $224.7 million of the outstanding principal, had been converted into approximately 5.7 million shares of common stock in advance of the redemption date.

Second-Quarter 2024 Financial Results

• Total revenue for the quarter ended June 30, 2024, was $90.3 million, reflecting 17% growth compared to total revenue of $77.2 million for the second quarter of 2023.
• Total revenue for second-quarter 2024 included ARIKAYCE net sales of $63.8 million in the U.S., $21.1 million in Japan, and $5.4 million in Europe and rest of world. Second-quarter 2024 sales demonstrated year-over-year growth of 11% in the U.S., 35% in Japan, and 37% in Europe and rest of world, reflecting continued growth trends for ARIKAYCE in these regions.
• Cost of product revenues (excluding amortization of intangibles) was $21.0 million for the second quarter of 2024, compared to $16.6 million for the second quarter of 2023, primarily reflecting increased sales volumes of ARIKAYCE.
• Research and development (R&D) expenses were $146.7 million for the second quarter of 2024, compared to $197.0 million for the second quarter of 2023. The year-over-year decrease in R&D expenses was primarily driven by the non-cash cost of the Adrestia acquisition in the prior-year quarter.
• Selling, general and administrative (SG&A) expenses for the second quarter of 2024 were $106.6 million, compared to $84.4 million for the second quarter of 2023. The year-over-year increase in SG&A expenses resulted primarily from increases in compensation and benefit-related expenses and stock-based compensation costs due to an increase in headcount.
• The Company recorded a non-cash expense of $103.7 million in the second quarter of 2024, reflecting the change in fair value of deferred and contingent consideration liabilities associated with previous acquisitions, which primarily resulted from the increase in our share price during the quarter.
• For the second quarter of 2024, Insmed reported a net loss of $300.6 million, or $1.94 per share, compared to a net loss of $244.8 million, or $1.78 per share, for the second quarter of 2023.

Balance Sheet, Financial Guidance, and Planned Investments

• As of June 30, 2024, Insmed had cash and cash equivalents totaling $1,246.8 million.
• Insmed is reiterating its guidance for full-year 2024 global ARIKAYCE revenues in the range of $340 million to $360 million, representing 15% year-over-year growth at the midpoint compared to 2023.

About ARIKAYCE

ARIKAYCE is approved in the United States as ARIKAYCE^® (amikacin liposome inhalation suspension), in Europe as ARIKAYCE^® Liposomal 590 mg Nebuliser Dispersion, and in Japan as ARIKAYCE^® inhalation 590 mg (amikacin sulfate inhalation drug product). 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 to improve patient care.

About Brensocatib 

Brensocatib is a small molecule, oral, reversible inhibitor of dipeptidyl peptidase 1 (DPP1) being developed by Insmed for the treatment of patients with bronchiectasis, CRSsNP, and other neutrophil-mediated diseases. DPP1 is an enzyme responsible for activating neutrophil serine proteases (NSPs), such as neutrophil elastase, in neutrophils when they are formed in the bone marrow. Neutrophils are the most common type of white blood cell and play an essential role in pathogen destruction and inflammatory mediation. In chronic inflammatory lung diseases, neutrophils accumulate in the airways and result in excessive active NSPs that cause lung destruction and inflammation. Brensocatib may decrease the damaging effects of inflammatory diseases such as bronchiectasis by inhibiting DPP1 and its activation of NSPs. Brensocatib is an investigational drug product that has not been approved for any indication in any jurisdiction.

About TPIP

Treprostinil palmitil inhalation powder (TPIP) is a dry powder formulation of treprostinil palmitil, a treprostinil prodrug consisting of treprostinil linked by an ester bond to a 16-carbon chain. Developed entirely in Insmed's laboratories, TPIP is a potentially highly differentiated prostanoid being evaluated for the treatment of patients with PAH, PH-ILD, and other rare and serious pulmonary disorders. TPIP is administered in a capsule-based inhalation device. TPIP is an investigational drug product that has not been approved for any indication in any jurisdiction.

IMPORTANT SAFETY INFORMATION AND BOXED WARNING 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.
