-
Safety profile: Respiratory adverse events, including cough, dyspnea, and bronchospasm, were the most common. Serious adverse events occurred in less than 5% of patients, aligning with prior safety data.
-
Additional indications: Trials exploring efficacy for Mycobacterium abscessus show promising early results, but conclusive data remains pending.
Regulatory and Post-Approval Studies
-
Post-marketing commitment: Insmed is conducting post-market studies to understand resistance development and long-term safety, aligned with FDA requirements.
-
Orphan drug designation: Maintained for MAC indication, incentivizing further development.
