Description of intervention(s) / exposure
This is an open label prospective phase 2 clinical trial of 25 adult patients diagnosed with uncontrolled eosinophilic chronic rhinosinusitis (eCRS) with Nasal Polyps (NP) treated with Dupilumab for a 26 week plus a post-treatment visit at three months.

The Dupilumab treatment will consist of the following:

Dupilumab
• Trade name: Dupixent
• Dosage regimen: for chronic rhinosinusitis 300mg subcutaneous injection once every 2 weeks for 24 weeks.
• Participants will also undergo a blood test, endoscopy and FENO (fractional exhaled nitric oxide) test at each second visit (once per month). Adverse and serious adverse event recording will occur at each visit.
