Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the efficacy of orally administered essentials oils (SIA capsules) compared with placebo for 2 weeks in adults with acute rhinosinusitis. ;Secondary Objective: To assess the safety of 2 weeks of oral treatment with essentials oils (SIA capsules) compared with placebo in adults with acute rhinosinusitis. ;Primary end point(s): 1. Difference in mean MSS(INV) scores at Visit 4 (SIA vs. placebo) 2. Difference in mean MSS(INV) scores at Visit 3 (SIA vs. placebo) ;Timepoint(s) of evaluation of this end point: Visit 3 and Visit 4

Secondary

MeasureTime frame
Secondary end point(s): 1. Difference in mean MSSPAT scores in the evening before Visit 3 (SIA vs. placebo) 2. Difference in mean MSSPAT scores in the evening before Visit 4 (SIA vs. placebo) 3. Difference in mean MSSINV scores at Visit 2 (SIA vs. placebo) 4. Difference in mean MSSPAT scores in the evening before Visit 2 (SIA vs. placebo) The secondary efficacy endpoint “Differences in responder rates at Visits 2, 3 and 4 (SIA vs. placebo)” will be analysed using the generalized linear mixed model with binary outcome using Baseline (Visit 1) as covariate, patient as random effect repeated in visit. The respective visit (Visit 2, Visit 3 or Visit 4) will be selected from the model by using respective contrasts. . A responder is defined by the investigator’s and subject’s assessments according to the definition in chapter 9.11. The order of testing will be as follows: 5. Difference in responder rates at Visit 4 (SIA vs. placebo) by investigator 6. Difference in responder rates at Visit 4 (SIA vs. placebo) by patient 7. Difference in responder rates at Visit 3 (SIA vs. placebo) by investigator 8. Difference in responder rates at Visit 3 (SIA vs. placebo) by Patient 9. Difference in responder rates at Visit 2 (SIA vs. placebo) by investigator 10. Difference in responder rates at Visit 2 (SIA vs. placebo) by patient ;Timepoint(s) of evaluation of this end point: Visit 2, Visit 3, Visit 4 and diary data over 15 days treatment period
