Brinsupri: First-Ever Treatment for Non–Cystic Fibrosis Bronchiectasis

What it is: Brinsupri (generic name brensocatib) is a newly FDA-approved oral medication—and it's the very first treatment specifically targeting non–cystic fibrosis bronchiectasis (NCFB), a chronic and progressive lung disease characterized by damaged airways, persistent coughing, and excess mucus production.

How it works: The drug functions by inhibiting key inflammatory enzymes in white blood cells, thereby reducing the cellular activity that contributes to lung damage and disease exacerbations.

Why it matters: Previously, treatment options for NCFB were limited to symptom management. This approval marks a long-awaited shift toward targeting the disease's underlying inflammatory mechanisms.

Market impact: Experts project Brinsupri could reach $3.7 billion in U.S. sales by 2031. Following the announcement, Insmed’s stock soared nearly 5%, reaching an all-time high—reflecting strong investor confidence.

In Summary

Brinsupri is groundbreaking not just for being the first treatment of its kind, but also for its targeted mechanism of action, offering real hope for improved quality of life in a previously underserved patient population. Its approval could pave the way for more precision-based therapies in chronic respiratory diseases.
