E.5 End points |
E.5.1 | Primary end point(s) |
1 - Part A and B: Change from baseline to Week 24 in opacification of sinuses assessed by CT scan using the Lund Mackay (LMK) score ; LMK total score is based on assessment of the CT scan findings for each sinus area. The extent of opacification is rated between 0 (normal) to 24 (total opacification).
2 - Part A and B: Change from baseline to Week 24 in sTSS ; The sinus Total Symptom Score (sTSS) is a composite score derived from the following individual items: nasal congestion (NC), anterior/posterior rhinorrhea, and facial pain/pressure. The total score ranges from 0-9. Higher scores on sTSS indicate greater overall symptom severity. |
