A Dose-Finding Study to Evaluate Ovarian Function and Vaginal Bleeding in Next Generation Rings (P06109/MK-8175A/MK-8342B-012)
A Multicenter, Randomized, Partially-blinded, Phase IIb Dose-finding Study on Ovarian Function, Vaginal Bleeding Pattern, and Pharmacokinetics Associated With the Use of Combined Vaginal Rings Releasing 17β-estradiol Plus Three Different Doses of Either Nomegestrol Acetate or Etonogestrel in Healthy Women Aged 18-35 Years.

Brief Summary
The primary objective of this trial was to identify at least one next generation ring (NGR) that demonstrates inhibition of ovulation (which was considered confirmed if in the subset of participants ovulation was observed in less than 15% of the participants at any time during the 3 treatment cycles of the study) and cycle control that was non-inferior to NuvaRing®, as judged by the incidence of breakthrough bleeding and/or spotting (BTB-S) during Cycle 3. The primary hypothesis was that at least 1 of the 6 NGRs would show inhibition of ovulation and cycle control during Treatment Cycle 3 that is non-inferior to NuvaRing®, as judged by the incidence of BTB-S.

Conditions
Outcome Measures
Primary Outcomes (3)
Percentage of Participants With Ovulation Incidence, by Cycle
Ovulation was defined as having 2 or more consecutive progesterone concentrations \>16 nmol/L within 5 days, confirmed by ultrasound evidence of ovulation (follicular rupture or preceding presence of a follicle-like structure \>15 mm in size).
Day 1 of Treatment Cycle 1 through Day 28 of Treatment Cycle 3 (Up to ~92 days)
Percentage of Participants With Progesterone Concentrations >16 Nmol/L, by Cycle
Maximum progesterone (Max P) was defined as the maximum progesterone value. Ovulation was defined as 2 or more consecutive progesterone concentrations \>16 nmol/L within 5 days during the 3 treatment cycles, supported by ultrasound evidence of ovulation. The Max P values greater than 16 nmol/L are presented by vaginal ring group and cycle.
Day 1 of Treatment Cycle 1 through Day 28 of Treatment Cycle 3 (Up to ~92 days)
Percentage of Participants With Breakthrough Bleeding and/or Spotting During Cycle 3
Breakthrough bleeding and/or spotting (BTB-S) is defined as any bleeding or spotting episode that occurred during the expected non-bleeding period that was neither an early nor a continued withdrawal bleeding. Bleeding = any bloody vaginal discharge that required one or more sanitary pads or tampons per day; Spotting = any bloody vaginal discharge that required no sanitary pads or tampons per day.
Day 1 Cycle 3 through Day 28 Cycle 3 (Up to ~28 days)
Secondary Outcomes (8)
Percentage of Participants With Absence of Withdrawal Bleeding and/or Spotting During Cycle 2
Day 1 Cycle 2 through Day 28 Cycle 2 (Up to ~28 days)
Intensity of Withdrawal Bleeding During Cycle 2
Day 1 Cycle 2 through Day 28 Cycle 2 (Up to ~28 days)
Intensity of Breakthrough Bleeding and/or Spotting During Cycle 3
Day 1 Cycle 3 through Day 28 Cycle 3 (Up to ~ 28 days)
Percentage of Participants Who Experienced At Least One Adverse Event
Up to ~92 days
Percentage of Participants Who Experienced At Least One Serious Adverse Event
Up to ~92 days
- +3 more secondary outcomes
Other Outcomes (1)
Number of Participants With Venous or Arterial Thrombotic/Thromboembolic Events
From Cycle 1 Day 1 up to 8 days after Day 28 of Cycle 3 (Up to ~92 days)
