NCT ID NCT05964465

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study looked at how dupilumab, a drug that blocks certain immune signals, improves smell in adults with chronic sinusitis and nasal polyps. Researchers measured changes in inflammation in the smell region using CT scans, endoscopy, and mucus samples over three months. The goal was to understand the mechanism behind smell improvement, not to test the drug's effectiveness.

What this could lead to

If successful, this could clarify how dupilumab restores smell, potentially leading to better treatments for nasal polyps and smell loss.

What could go wrong

This is a small, completed Phase 4 study (60 people) focused on understanding mechanisms, not proving long-term benefit. Results may not apply to all patients.
