Xolair under the microscope: how well does it work for nasal polyps in real life?
NCT ID NCT05626257
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how safe and effective Xolair is for adults with chronic rhinosinusitis and nasal polyps when used in routine care. 135 patients who were already prescribed Xolair were followed to track side effects and changes in symptoms. The goal was to see how the drug performs outside of strict clinical trial settings.
