Update 2.50 PM EST: Adds latest share price move and comments from SA analyst Stephen Ayers

Insmed (NASDAQ:INSM) shares soared by over 100% on Tuesday following the announcement that brensocatib, their oral candidate for treating a severe lung disease known as bronchiectasis, successfully met the primary endpoint and various secondary endpoints with statistical significance in a Phase 3 trial.

Reaching Milestones

Citing the topline results, Insmed declared that ASPEN, an international trial involving adults and adolescents with non-cystic fibrosis bronchiectasis (NCFB), achieved the primary objective with both 10 mg and 25 mg doses of brensocatib, leading to a reduction in the annual rate of pulmonary exacerbations compared to a placebo.

Future Plans

The biotech company based in Bridgewater, New Jersey, also unveiled intentions to submit a marketing application for brensocatib to the FDA in Q4 2024 for bronchiectasis, a condition impacting approximately 450,000 patients in the U.S.

Pending regulatory approvals, Insmed (INSM) aims to introduce brensocatib in mid-2025 in the U.S. and in the first half of 2026 in Europe and Japan.

Safety Record

In terms of safety, around 78% and 77% of patients receiving brensocatib at 10 mg and 25 mg doses respectively reported treatment-emergent adverse events, compared to approximately 80% of those administered a placebo.

Analyst’s Insight

Following the announcement, SA analyst Stephen Ayers upgraded Insmed (INSM) as the stock reached a 52-week high. Despite the promising potential of brensocatib in treating NCFB, Ayers highlighted the challenges ahead for the company, including its substantial debt burden.

“Navigating short-term pressures without losing sight of the long-term prospects awaiting Insmed requires a delicate balance,” the analyst noted.
