Summary

• Insmed held a commercial webinar on June 4, 2024, focusing on the market potential of ARIKAYCE, brensocatib, and TPIP.
• ARIKAYCE is currently approved for refractory Mycobacterium avium complex (MAC) lung disease and has potential to address approximately 275,000 patients.
• Brensocatib is being developed for bronchiectasis, chronic rhinosinusitis without nasal polyps (CRSsNP), and hidradenitis suppurativa (HS), with potential markets of over 1 million, 400,000, and 600,000 patients respectively.
• TPIP is being developed for pulmonary hypertension due to interstitial lung disease (PH-ILD) and pulmonary arterial hypertension (PAH), with potential markets of 135,000 and 90,000 patients respectively.
• The company anticipates significant growth in addressable patients through 2030, potentially reaching 2.5 million.
• Insmed believes these therapies have the potential to be firstor best-in-disease options, with peak sales potential exceeding $2 billion for brensocatib, $1 billion for ARIKAYCE, and $5 billion for TPIP.
• TPIP has shown a favorable safety profile and once-daily inhalation convenience, potentially differentiating it from other treatments.
• Brensocatib has demonstrated a statistically significant benefit on clinical worsening in bronchiectasis and is expected to be a new standard of care.
• ARIKAYCE has shown a statistically significant culture conversion benefit at Month 7 compared to active control.

Industry Context

The presentation highlights Insmed's focus on rare and chronic respiratory diseases, aligning with the growing trend of pharmaceutical companies targeting niche markets with high unmet needs. The company's emphasis on firstor best-in-disease therapies reflects a competitive landscape where differentiation is key to success. The mention of sotatercept suggests that Insmed is aware of and planning for the evolving treatment landscape in PAH.

Comparison to Industry Standards

• The document references the launch of ARIKAYCE as a top 10 non-oncology rare disease launch in 2018, setting a benchmark for future product launches.
• The document references other specialty pulmonary medications such as those for severe eosinophilic asthma and idiopathic pulmonary fibrosis, with list prices of ~$40k and ~$96k respectively, as precedents for launch pricing of brensocatib.
• The document notes that the Phase 3 STELLAR trial suggests that sotatercept will be complementary with treprostinil products, indicating an awareness of competitive products in the PAH space.

Stakeholder Impact

• Shareholders are likely to view the presentation positively due to the potential for significant revenue growth.
