Anti-Inflammatory Agent in Sinusitis

Measurement of secondary outcome- BSIT (brief smell identification test) is a 12-item test measuring sense of smell. This is a multiple choice test with one correct answer out of four possible answer choices. This test features distinct types of smells. Minimum score: 0/12, which indicates that none of the correct answers were chosen on the 12-item test. Maximum score: 12/12, which indicates that all of the correct answers were chosen on the 12-item test. The higher the score, the better the outcome. Only one out of the four possible answer choices for each multiple choice question is correct. There are no subscales. This secondary outcome measures sense of smell by Brief Smell Identification Test (B-SIT) at baseline (visit 1) and 12 weeks (visit 5) in the AZD1981 group vs. the placebo group.

Time frame: Baseline and Week 12

Population: The secondary outcome was the mean change from baseline to 12 weeks of BSIT scores in the AZD1981 treated group compared to the placebo-treated group.

Measurement of secondary outcome: sinus CT scan scores by Lund-Mckay scores. We measured sinus radiographic severity with Lund-Mackay scores of 0 to 24. 0 was the least severe and 24 was the most severe. This secondary outcomes included change in radiographic severity of sinus disease, as measured by sinus CT scan scores at baseline and 12 weeks in the AZD1981 group vs. the placebo group.

Time frame: Baseline and Week 12

Population: The secondary outcome was the mean change in Lund-Mackay scores of sinus CT scans from baseline to 12 weeks in the AZD1981 treated group compared to the placebo-treated group.

Measure Description: Measurement of Primary outcome- 0-4 scale in each nostril, total is 8. The total polyp score is the sum of the right and left nasal polyp score. Maximum is 8, minimum is 0. Higher score indicates worse disease. 0 =No polyps 1=Small polyps in the middle meatus not reaching below the inferior border of the middle turbinate 2=Polyps reaching the lower border of the middle turbinate or polyp medial to the middle turbinate 3 = Large polyps reaching the lower border of the inferior turbinate 4 =Large polyps causing complete obstruction. The primary outcome measured change in polyp size and secondary outcomes included change in radiographic severity of sinus disease, quality of life, and nasal symptoms as measured by Sino Nasal Outcome Test-22 (SNOT-22) and sense of smell by Brief Smell Identification Test (B-SIT) at 12 weeks in the AZD1981 group vs. the placebo. These were done at the baseline visit and the Week 12 visit.

Time frame: Baseline and Week 12

Population: The primary outcome was the mean change from baseline to 12 weeks in the size of nasal polyps as measured by the total polyp score in the AZD1981 treated group compared to the placebo-treated group.

Measurement of secondary outcome- the SNOT-22 test contains 22 items regarding patient-reported outcomes of sino-nasal symptom severity on a 0-5 scale for each item. 0 is no problem and 5 is problem as bad as it can be, so higher values represent a worse outcome than lower values. The subscale is 0 - 5 of each of the 22 items and the total score is the sum of the subscales of all 22 items. The minimum total score is 0/110. The maximum total score is 110/110. This secondary outcome measured change in patient-reported outcomes of nasal symptoms as measured by Sino Nasal Outcome Test-22 (SNOT-22) over 12 weeks in the AZD1981 group vs. the placebo group.

Time frame: Baseline and Week 12

Population: This secondary outcome was the mean change from baseline to 12 weeks in sinonasal symptoms detailed in the SNOT-22 as measured by the total polyp score in the AZD1981 treated group compared to the placebo-treated group.

Measurement of secondary outcome- 0 to 10 scale bilaterally that measures how subjective sinus symptom severity, with 0 being the least troublesome to 10 being the most troublesome over 12 weeks in the AZD1981 group vs. the placebo group.

Time frame: Baseline and Week 12

Population: The secondary outcome was the mean change from baseline (visit 1) to 12 weeks (visit 5) of the VAS scores in the AZD1981 treated group compared to the placebo-treated group.
