Feasibility will be measured by the recruitment rate, withdrawal rate, data completion rate, and adherence rate. Recruitment rate will be quantified by the percentage of eligible participants enrolled relative to the number of participants contacted. Feasibility will be marked as a minimum of 1-2 participants enrolled per month. Withdrawal/dropout rate will be quantified by the percentage of participants who drop out of the study. The upper limit of the 95% confidence interval (CI) for dropout rate should not exceed 20%. Adherence and data completion will bhe proportion of participants who strictly follow the study protocol (the "per-protocol group") will be estimated with a 95% CI. This includes adherence to treatment (taking the medication correctly for six weeks), study completion (attending all required visits), and providing complete data. To be considered feasible, the lower limit of this 95% CI must be greater than 80%.
Tolerability will be measured by the frequency and nature of adverse events and medication adherence (i.e., missed dosage).
