What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Comparator: placeboDrug

  • Comparator: EstraceDrug

    Also called Estrace

    Estrace 0.5 mg or 2 mg tablets once daily for 7 days.

What is being measured

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

  1. Change From Baseline in Estrogen Receptor Beta (ERbeta) -Specific Gene Signature After Treatment With 2 mg, 0.5 mg, or no Estradiol (Placebo) at Day 7

    Subset of genes on the log ratio intensity scale from a microarray platform - signature was pre-specified from an internally conducted study in knock-out mice treated with estrogens- quantified as a ratio of up regulated versus down regulated genes

    Measured: Baseline and Day 7

Secondary outcomes (1)
  1. Change From Baseline in Minor Gland Salivary Flow Rate After Treatment With 2 mg Estradiol vs Placebo at Day 7.

    Change from baseline in unstimulated labial gland saliva flow rate at Day 7

    Measured: Baseline and Day 7

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Comparator: Estrace in people with Postmenopause, run by Merck Sharp & Dohme LLC.

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 11 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: finished, as of the sponsor's last update on 16 Mar 2016. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 29 Jul 2010). 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?

Change From Baseline in Estrogen Receptor Beta (ERbeta) -Specific Gene Signature After Treatment With 2 mg, 0.5 mg, or no Estradiol (Placebo) at Day 7 (time frame: Baseline and Day 7). 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 16 Mar 2016; AzTrials last refreshed its copy on 7 Nov 2026.
