Efficacy and Safety of Etonogestrel + 17β-Estradiol Vaginal Ring in Women at Risk for Pregnancy (MK-8342B-061)

May 8, 2024 updated by: Organon and Co

A Phase 3, Single Arm, Clinical Trial to Study the Contraceptive Efficacy and Safety of the MK-8342B (Etonogestrel + 17β-Estradiol) Vaginal Ring in Healthy Women 18 Years of Age and Older, At Risk for Pregnancy

The purpose of this study is to assess the contraceptive efficacy of the Etonogestrel (ENG) + 17β-Estradiol (E2) vaginal ring in women between 18 and 35 years of age based on the number of in-treatment pregnancies as expressed by the Pearl Index (PI). The study will also assess the safety and tolerability of the ENG-E2 vaginal ring.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of In-Treatment Pregnancies Per 100 Woman-Years of Exposure in Participants 18-35 Years of Age (Pearl Index)
Time Frame: Up to 1 year (13 28-day cycles)
The Pearl Index is the number of in-treatment pregnancies with a conception date in any of the in-treatment cycles, divided by all treatment cycles in each participant from the first treatment cycle to the last treatment cycle (due either to discontinuation or completion), regardless of whether a treatment cycle was "at risk" or not. One woman-year is defined as 13 treatment cycles x 28 days. These efficacy results should be interpreted with caution. Due to the discontinuation of product development and early trial termination, the number of "at risk" treatment cycles in the denominator is based on uncleaned diary data.
Up to 1 year (13 28-day cycles)
Number of Participants With One or More Adverse Events (AEs)
Time Frame: From insertion of the first vaginal ring up to and including 14 days after removal of the last vaginal ring (up to approximately 1 year)
An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of the Sponsor's product, is also an AE.
From insertion of the first vaginal ring up to and including 14 days after removal of the last vaginal ring (up to approximately 1 year)
Number of Participants Who Discontinued Treatment Due to an AE
Time Frame: From insertion of the first vaginal ring up to and including 14 days after removal of the last vaginal ring (up to approximately 1 year)
An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of the Sponsor's product, is also an AE.
From insertion of the first vaginal ring up to and including 14 days after removal of the last vaginal ring (up to approximately 1 year)
Number of Participants With One or More Drug-related AEs
Time Frame: From insertion of the first vaginal ring up to and including 14 days after removal of the last vaginal ring (up to approximately 1 year)
An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of the Sponsor's product, is also an AE. An investigator who is a qualified physician determined whether an AE is drug-related.
From insertion of the first vaginal ring up to and including 14 days after removal of the last vaginal ring (up to approximately 1 year)
Number of Participants Who Discontinued Treatment Due to a Drug-related AE
Time Frame: From insertion of the first vaginal ring up to and including 14 days after removal of the last vaginal ring (up to approximately 1 year)
