| Trial ID | Title | Status | Sponsor | Phase | Start Date | Summary |
|---|---|---|---|---|---|---|
| NCT00369967 ↗ | Quick Start Initiation of the Contraceptive Vaginal Ring in Adolescents | Terminated | American College of Obstetricians and Gynecologists | N/A | 2007-02-01 | We hypothesize that using "quick start" initiation of the contraceptive vaginal ring in adolescents seeking birth control will improve compliance compared to traditional start. We will conduct a randomized controlled trial comparing "quick start" to traditional start initiation of the contraceptive vaginal ring in adolescents seeking birth control. The primary study outcome is method continuation at 3, 6, and 12 months. Secondary outcomes include abnormal bleeding, product satisfaction, and adverse events. |

| NCT00369967 ↗ | Quick Start Initiation of the Contraceptive Vaginal Ring in Adolescents | Terminated | Virginia Commonwealth University | N/A | 2007-02-01 | We hypothesize that using "quick start" initiation of the contraceptive vaginal ring in adolescents seeking birth control will improve compliance compared to traditional start. We will conduct a randomized controlled trial comparing "quick start" to traditional start initiation of the contraceptive vaginal ring in adolescents seeking birth control.

| NCT00612508 ↗ | Hormonal Contraception and Vaginal Health | Completed | Oregon Clinical and Translational Research Institute | N/A | 2007-05-01 | The purpose of this study is to help determine if the route by which women receive hormonal contraception causes different changes to occur in the lining of the vagina. The investigators plan to compare an oral route (taking birth control pills) with a vaginal route (using a vaginal ring). |

| NCT00710606 ↗ | Comparison of Serum Contraceptive Hormone Levels Between Normal Weight and Obese Users of the NuvaRing® | Completed | Organon | N/A | 2008-06-01 | There are over 60 million women of reproductive age in the U.S. and a majority of these women qualify as overweight or obese. Evidence suggests that there is an association between increased body weight and decreased contraceptive efficacy. Studies with the combined hormonal contraceptive patch (Evra®) and the subdermal contraceptive implant (Norplant®) demonstrate higher failure rates in heavier versus lighter women. Weight related differences in the effectiveness of NuvaRing® need further study. A single secondary analysis of pooled data from Phase III clinical trials of NuvaRing® noted no difference in pregnancy rates among women in the highest weight decile (>166#) versus the rest of the study population using the ring. (Westhoff, 2005) The finding of no difference, however, was influenced by too few obese subjects in the analysis which contributed to wide confidence limits. Additional studies are needed to explore how well the contraceptive ring functions to maintain effective serum steroid concentrations to suppress ovarian activity in obese women. This investigation focused on evaluating mean serum concentrations of hormones released in obese and normal weight women using the NuvaRing® . This study was a prospective clinical trial. Normal weight women are defined as women with a BMI 19-24.9 and obese women are those with a BMI 30-39.9. We recruited forty adult women interested in initiating the combined hormonal contraceptive ring to two months of use to complete analysis of at least 34 subjects (17 normal weight, 17 obese). We compared mean serum concentrations of ethinyl estradiol (E2) and etonogestrel (ENG) along with additional markers for ovarian suppression. These markers included sonographic evidence of follicular development and ovulation as well as circulating E2 levels which strongly correlate with follicular development and endometrial proliferation during the second month of NuvaRing® use. Assessment of these parameters will translated to understanding contraceptive-mediated suppression of ovarian function in these two groups. Subjects also logged patterns of ring use and bleeding patterns during the study period. |
