Brief summary

This is a feasibility, multi-center, open-label, non-significant risk device study for a non-hormonal contraceptive ring.

Detailed description

The purpose of this clinical trial is to assess the ability of Ovaprene™ to prevent sperm from penetrating midcycle cervical mucus. In addition, safety, release of ingredients, acceptability and fit will be assessed.

All Enrolled Population
Healthy, sexually active women who are not at risk for pregnancy due to previous female tubal sterilization will receive both Ovaprene and the Caya diaphragm throughout the course of the trial. The purpose of the Caya PCT cycle is to ensure that in this study population and at these sites, results that are expected to be observed in a PCT cycle with an approved vaginal barrier can be replicated.

Participants That Could Correctly Insert, Position and Remove the Ovaprene Device

Number of participants that required written instructions, those who required written and verbal instructions and those who needed physical assistance.

Time frame: Visit 3 (BP3, Day 15-20); Visit 7 (OS1, Day 84); Visit 12 (OP1a, Day 112); Visit 13 (OP2a, Day 122-132); Visit 17 (OP1b, Day 140); UNS could occur at any point during the 175 day study duration

Population: The sites were reminded during a site call on 2/11/2019 that they were to allow patients to try to insert, position, and remove the device using only written instructions. After that point, there were 20 patients who were given the opportunity to do this. Not all participants attempted this at all visits.
