What researchers measure

Primary outcomes

  1. Proportion of Dosing Instances Among User Population Taken Within 120 Hours (5 Days) of Most Recent Episode of Unprotected Sex.

    The first primary endpoint is the proportion in which the denominator includes all dosing instances of the IP and the numerator includes all dosing instances of the IP which were taken within 120 hours (5 days) of the subject's most recent episode of unprotected sex.

    Time frame: Up to 6 Weeks

  2. Proportion of Dosing Instances Among User Population in Which no More Than One Tablet Was Taken.

    The second primary endpoint is the proportion in which the denominator is all discrete dosing instances of the IP and the numerator includes all dosing instances where no more than one tablet was taken.

    Time frame: Up to 6 Weeks

  3. Proportion of Female Selectors Who Are Not Pregnant at the Time of Selection Decision.

    The third primary endpoint is the proportion in which the denominator includes all females who selected to use the product (regardless of whether they purchased/used) and the numerator includes all female selectors who were not pregnant at the time of the selection decision.

    Time frame: Day 1

Participant flow

In order to be as representative as possible of the OTC EC-seeking population, when potential subjects came to a site looking to purchase EC, they've been offered the opportunity to participate in the study. If approximately 75% of subjects pass the screening criteria, self-select and both qualify and agree to purchase and enter the use phase, it was expected that up to 1270 subjects will need to be interviewed to yield 950 purchasers and 760 in use population.
