What is being measured
The primary outcome is the main question the study is designed to answer.
Number of In-Treatment Pregnancies Per 100 Woman-Years of Exposure in Participants 18-35 Years of Age (Pearl Index)
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.
Measured: Up to 1 year (13 28-day cycles)
Number of Participants With One or More Adverse Events (AEs)
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.
Measured: 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
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.
Measured: 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
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. An investigator who is a qualified physician determined whether an AE is drug-related.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing ENG-E2 125 μg/300 μg vaginal ring in people with Contraception, run by Organon and Co.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 17 May 2024. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 25 Sep 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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 study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 May 2024.
