What is being measured
The primary outcome is the main question the study is designed to answer.
The primary efficacy variable will be the proportion of volunteers with ovulation in at least one of the treatment cycles 2 and 3, based on the binary variable ovulation (i.e. Hoogland score 6) with the levels yes and no
Measured: 12 months
Secondary outcomes (4)
Assessment of ovarian activity in treatment cycles 2 and 3
Measured: 12 months
Course of gonadotropins (FSH, LH)
Measured: 12 months
Endometrial growth
Measured: 12 months
Pharmacokinetics of estrogen and progestin in treatment cycle 3
Measured: 12 months

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing BAY86-4891 (Estradiol / Drospirenone) in people with Contraception, run by Bayer at 2 sites in Germany.
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 2 inclusion and 4 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: finished, as of the sponsor's last update on 2 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
The primary efficacy variable will be the proportion of volunteers with ovulation in at least one of the treatment cycles 2 and 3, based on the binary variable ovulation (i.e. Hoogland score 6) with the levels yes and no (time frame: 12 months). 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 2 Dec 2014; AzTrials last refreshed its copy on 8 Nov 2026.
