Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Contraceptive Efficacy of MR-100A-01 When Used Over Thirteen 28-day Cycles in Healthy, Post-menarcheal, Premenopausal, Heterosexually Active Female Subjects of Childbearing Potential Who Are at Least 16 Years of Age and at Risk of Pregnancy | approximately 12 months (13 cycles with each cycle for 4 weeks) | The Pearl Index, defined as the number of pregnancies per 100 women years, was calculated as: Pearl Index = (1300×number of on-treatment pregnancies)/number of evaluable cycles. Evaluable cycles were defined as the complete or incomplete 28-day cycles in which vaginal intercourse occurred and in which no back-up contraception was used based on the electronic diary data, unless a pregnancy occurred in such a cycle. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cumulative Probability of Pregnancy at the End of Cycle 13 | approximately 12 months (13 cycles with each cycle for 4 weeks) | Cumulative pregnancy rates over 1 year evaluated using life table analysis |
| Method Failure Pearl Index (PI) | approximately 12 months (13 cycles with each cycle for 4 weeks) | The method failure PI is defined as PI among all complete or incomplete on therapy cycles in which intercourse occurred and protocol guidelines for patch applications were appropriately followed and without any major protocol deviations |
| Incidence of Treatment Emergent Adverse Events (TEAEs) | approximately 12 months (13 cycles with each cycle for 4 weeks) | A summary of the count and percentage of subjects (2%) reporting a TEAE |
| Incidence of Serious Adverse Events (SAEs) | approximately 12 months (13 cycles with each cycle for 4 weeks) | A summary of count and percentage of subjects reporting a Treatment emergent SAE |
| Number of Participants Reported Application Site Disorder | approximately 12 months (13 cycles with each cycle for 4 weeks) | Number of participants reported Application site disorder which were treatment emergent adverse events (TEAE) |
| Number of Days of Unscheduled Bleeding/and or Spotting | approximately 12 months (13 cycles with each cycle for 4 weeks) | The observed number of days of unscheduled bleeding/and or spotting |
| Number of Bleeding and/or Spotting Episodes | approximately 12 months (13 cycles with each cycle for 4 weeks) | Number of Bleeding and/or Spotting episodes |
| Proportion of Subjects Reporting Unscheduled Bleeding/and or Spotting Episodes | approximately 12 months (13 cycles with each cycle for 4 weeks) | Incidences (percentage of subjects) of unscheduled bleeding and/or spotting episodes within each cycle |
| Adhesion Performance as Measured by Adhesion Scores [Patch Adhesion] | approximately 12 months (13 cycles with each cycle for 4 weeks) | The descriptive figures of adhesion performance reported by subjects in their e-Diary on all days except during the patch-free week on the following 5-point scale. Score 0 indicates best adhesion and score 4 indicates worst adhesion. Higher score indicates poor adhesion. Self-Reported Scoring System of Patch Adhesion Assessment Score 0 - The patch has essentially no lift off the skin (≥90% adhered) Score 1 - Only some edges of the patch lift off the skin (≥75% to \<90% adhered) Score 2 - Less than half of the patch lifts off the skin (≥50% to \<75% adhered) Score 3 - The patch is not detached, but more than half of it lifts off the skin without falling off (\>0% to \<50% adhered) Score 4 - The patch is detached and is completely off the skin (0% adhered) |
