What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Ovulation Rate in Cycle 1

    Ovulation rate was defined as the percentage of subjects who ovulated (mid-luteal Progesteron [P4] level greater than or equal to [>=] 10 nanogram per milliliter [ng/mL] and/or pregnancy).

    Measured: Up to 1 month

Secondary outcomes (1)
  1. Number of Subjects With Clinical Pregnancy in Cycle 1

    Clinical pregnancy was defined as the existence of at least one ultrasonographically confirmed gestational sac in the uterus with fetal heart activity.

    Measured: Up to 1 month

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Anastrozole 1 mg, Anastrozole 5 mg and Anastrozole 10 mg in people with Anovulation, run by EMD Serono at 1 site in United States.

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 3 inclusion and 2 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 17 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

Yes. Results are posted in the registry (first posted 17 Jul 2018). 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?

Ovulation Rate in Cycle 1 (time frame: Up to 1 month). 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 Jul 2018.
