How Investors Are Reacting To Insmed (INSM) Priority Review Acceptance
Insmed (INSM) announced FDA Priority Review for ARIKAYCE in MAC lung disease, with a PDUFA date of January 28, 2027, based on positive Phase 3b ENCORE data. The review could expand ARIKAYCE's use to earlier-stage patients, potentially diversifying Insmed's revenue. Investors focus on U.S. brensocatib launch timing as a key factor, with ARIKAYCE's update influencing long-term revenue mix. Insmed projects $4.1b revenue and $1.0b earnings by 2029, with analysts offering varying forecasts.
