Overview
Brief Summary
This clinical trial will compare treatment in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma. The patients will be randomized to treatment with the biologic drug, Mepolizumab, or the biologic drug Mepolizumab combined with Functional Endoscopic Sinus Surgery (FESS).
The aim of this study is to evaluate the effect of combined treatment with biologic treatment and surgery vs. biologic treatment only.
The hypothesis is that surgical removal of polyps and inflamed tissue from the nasal sinuses will increase the effect of the biologic treatment, leading to a lower disease burden after 6 months of treatment, compared with biologic drugs only. Furthermore, combined biologics and surgery will keep a lower disease burden and better general health after 12 months of treatment than biologics alone.
Inclusion criteria:
-
Patients ≥ 18 years old at the time of signed informed consent (no upper limit)
-
Patients who are referred to the outpatient clinic for the following reasons:
- Doctor's diagnosis of CRS
-
NPS ≥ 2+2 out of a score of 8 (max)
-
Severity measured as an SNOT22 score > 35
-
One FESS in general anaesthesia performed prior to inclusion (no time limitations)
-
No course of systemic steroids within the last 3 months, whereas a daily low dose is allowed
-
Possible doctor's diagnosis of asthma
-
Type 2 inflammation
Exclusion criteria:
-
Patients who, because of language barriers, are not able to understand written information and, thus, are not able to answer questionnaires
-
Patients who currently receive biologics for any other disease
-
Patients who have previously or currently received biologics for CRS or asthma
-
Patients who are not able to give informed consent (i.e., patients who are permanently incapable)
-
Patients who meet ≥1 of the following:
- Malignant lung disease
- Cardiac disease of clinical importance
- Current pregnancy and breastfeeding, as well as planning to be pregnant in the near future
- Unwillingness to have FESS performed
-
Patients needing FESS or systemic steroids (OCS) during the study period will be excluded after an unscheduled visit (last observation carried forward (LOCF))
-
Patients who are not eligible because of the investigator's judgement
The effect of the treatment will be evaluated with objective procedures and questionnaires related to CRSwNP and asthma after 3, 6 and 12 months.

Outcomes
Primary Outcomes
Change in The Sino-Nasal Outcome Test 22 (SNOTT22) score
Time Frame: 6 months
The success rate indicated by a significant change in health-related quality of life related to nasal symptoms measured with the questionnaire SNOT22. The outcomes to be evaluated are the differences in success rates between the two treatment arms Minimum score = 0 and maximum score = 110 with high scores indicating a large rhinosinusitis-related health burden.

- Change in Nasal Polyp Score (NPS)(3 and 6 months follow up)
- Change in Forced Expired Volume in the first second (FEV1)(6 and 12 months follow up)
- Change in forced vital capacity (FVC)(3, 6, and 12 months follow up)

- Change in ratio between FEV1/FVC(3, 6, and 12 months follow up)
- Change in nitric oxide in exhaled air(6 and 12 months follow up)
- Change in middle ear pressure(12 months)
- Change in olfactory function(6 and 12 months follow up)
- Change in Functional Outcomes of Sleep Questionnaire (FOSQ) score(3, 6, and 12 months follow up)
