Actual Use Trial

Brief summary

An actual use trial to demonstrate that consumers will not exceed the labeled daily dose of Aleve 24 Hour at an unacceptable rate. Two aspects of consumer use will be evaluated: 1) the frequency at which consumers exceed the label-defined daily dose, thus putting themselves at clinical risk, and 2) the reasons for exceeding the labeled daily dose.

MeasureTime frameDescription
Estimated Percentage of Misuse for Non-Therapeutic Reasons28 daysThe primary objective of this trial was to determine the percentage of non-therapeutic misuse. Two aspects of consumer use of Aleve 24 Hour were examined: the frequency at which consumers exceeded the label-defined daily dose modified by those who did so for non-therapeutic reasons.

Estimated Percentage of Misuse for Non-Therapeutic Reasons Using the First 10-Day Treatment Course28 daysThis endpoint was an assessment of whether the rate of non-therapeutic misuse exceeded the pre-defined acceptable threshold for non-therapeutic misuse. The difference lay in the estimation of misuse in the Patterns of Use Cohort by using 10-day treatment courses rather than by use day. A treatment course for each subject began on the first day they recorded taking one or more tablets which was followed by nine consecutive evaluable days.
