ListOutcomeTime frameDescription
PrimaryPercentage of Participants With Ovulation Incidence, by CycleDay 1 of Treatment Cycle 1 through Day 28 of Treatment Cycle 3 (Up to ~92 days)
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).
PrimaryPercentage of Participants With Progesterone Concentrations >16 Nmol/L, by CycleDay 1 of Treatment Cycle 1 through Day 28 of Treatment Cycle 3 (Up to ~92 days)
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.
PrimaryPercentage of Participants With Breakthrough Bleeding and/or Spotting During Cycle 3Day 1 Cycle 3 through Day 28 Cycle 3 (Up to ~28 days)
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.
SecondaryPercentage of Participants With Absence of Withdrawal Bleeding and/or Spotting During Cycle 2Day 1 Cycle 2 through Day 28 Cycle 2 (Up to ~28 days)
Withdrawal bleeding and/or spotting is considered any bleeding or spotting episode that starts during or continues into the expected bleeding period (i.e., when the ring has been removed the last week of the cycle). Absence of withdrawal bleeding is no withdrawal bleeding and/or spotting episodes during an expected bleeding period when the ring has been removed.
SecondaryIntensity of Withdrawal Bleeding During Cycle 2Day 1 Cycle 2 through Day 28 Cycle 2 (Up to ~28 days)
Intensity of withdrawal bleeding during Cycle 2 was defined as the ratio of the number of withdrawal bleeding days divided by the number of withdrawal bleeding and/or spotting days. Withdrawal bleeding and/or spotting is considered any bleeding or spotting episode that starts during or continues into the expected bleeding period (i.e., when the ring has been removed the last week of the cycle). Absence of withdrawal bleeding is no withdrawal bleeding and/or spotting episodes during an expected bleeding period when the ring has been removed.
SecondaryIntensity of Breakthrough Bleeding and/or Spotting During Cycle 3Day 1 Cycle 3 through Day 28 Cycle 3 (Up to ~ 28 days)
Intensity of breakthrough bleeding and/or spotting (BTB-S) during Cycle 3 was defined as the ratio of the number of breakthrough bleeding days divided by the number of breakthrough bleeding and/or spotting days. 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.
SecondaryPercentage of Participants Who Experienced At Least One Adverse EventUp to ~92 days
An adverse event (AE) is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not it is considered related to the study drug.
SecondaryPercentage of Participants Who Experienced At Least One Serious Adverse EventUp to ~92 days
A serious adverse event (SAE) is an AE that results in death, is life threatening, requires or prolongs an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, is a cancer, is associated with an overdose; or is another important medical event deemed such by medical or scientific judgment.
SecondaryPercentage of Participants Who Experienced At Least One Drug-Related Adverse EventUp to ~92 days
An adverse event (AE) is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not it is considered related to the study drug. A drug-related AE was defined as any AE for which there is reasonable possibility of drug relationship as assessed by the Investigator.
SecondaryPercentage of Participants With Any Drug-Related Serious Adverse EventUp to ~92 days
A serious adverse event (SAE) is an AE that results in death, is life threatening, requires or prolongs an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, is a cancer, is associated with an overdose; or is another important medical event deemed such by medical or scientific judgment. A drug-related SAE was defined as any SAE for which there is reasonable possibility of drug relationship as assessed by the Investigator.
SecondaryPercentage of Participants Who Discontinued Study Drug Due to an Adverse EventUp to ~92 days
An adverse event (AE) is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not it is considered related to the study drug.
OtherNumber of Participants With Venous or Arterial Thrombotic/Thromboembolic EventsFrom Cycle 1 Day 1 up to 8 days after Day 28 of Cycle 3 (Up to ~92 days)Venous or arterial thrombotic/thrombo-embolic events, (VTEs or ATEs) (e.g., deep venous thrombosis, pulmonary embolism, myocardial infarction, cerebrovascular accident) were assessed.
