Efficacy:
Sample size of 23 participants per treatment group will provide 80% power to detect a Minimal Clinically Important Difference (MCID) of 0.5 in Day-time symptom score (DNSS) between active treatment verses placebo, if the DNSS is normally distributed with a SD of 0.50 change, with a significance level of (alpha) of 0.05 using a 2-sided 2-sample t-test. Assuming that 10% of participants may not be evaluable, a total of 30 participants per group is required.
Data analysis: Efficacy analyses will be carried out on intent-to-treat population, consisting of all participants who are randomized, exposed to at least 4 doses (2 days) of the study product, and then attended at least one follow-up check-in after treatment initiation. This will include data from withdrawn participants. Safety analyses were based on data of all participants who received at least one dose of study product.

All of the data will be expressed as mean ± standard deviation unless otherwise specified. Characteristic comparability between groups at baseline will be assessed by independent t-test for continuous data, or by Pearson chi-square test for categorical data. Changes from baseline of measured metabolic parameters at each visit will be analyzed individually between groups by independent t-test. In addition, each individual variable will be analyzed within group by repeated-measures analysis of variance. Pathology assessments at baseline and end of study will be statistically analyzed within group by paired t-test, and between groups by independent t-test. Throughout the analysis, the underlying distributional assumptions of the statistical models should have been met; otherwise, the corresponding nonparametric tests will be used. Interim Statistical Analysis: There will be no interim statistical analysis for efficacy or safety. The investigator will review adverse events as they arise.
