About this study

Official title: Effect of Combined Estradiol and Drospirenone Treatment Versus Combined Estradiol and Medroxyprogesterone Acetate Treatment on Endothelial Function: A Crossover Study

This study compares the effects of two common hormone medications on the heart and blood vessels of healthy post-menopausal women over the age of 45.

The study will take place over the course of about 5 months. Each subject will take two different medications over two six-week periods. They will be randomized at the beginning of the study to either estradiol+medroxyprogesterone acetate or estradiol+drospirenone for the first period, and will receive the other medication the second six-weeks of the study. At the very beginning of the study and at the end of each six-week treatment period, subjects will come to the hospital various tests including non-invasive blood vessel imaging tests, blood draws to test the levels of certain hormones in the body, an oral glucose tolerance test, a test to monitor renal blood flow, and 24-hour blood pressure monitoring. Between treatment periods, there will be a four-week medication-free washout period.

What is being measured

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

  1. Brachial Artery Reactivity % Flow Mediated Dilation (BAR %FMD)

    This crossover study examined the effects of E+MPA versus E+DRSP on brachial artery reactivity (BAR) assessed after six weeks of treatment. BAR is a noninvasive measure of endothelium-dependent flow-mediated vasodilation (FMD) of the brachial artery. With this technique, inflation of an arm blood pressure cuff to suprasystolic blood pressure causes relative ischemia downstream to the cuff. Upon deflation, a brief state of increased blood flow occurs (reactive hyperemia), and the resulting increase in shear stress causes nitric oxide release and resulting vasodilation of the brachial artery (flow-mediated vasodilation). The flow-mediated changes in brachial artery diameter can be imaged by ultrasound and measured as an index of peripheral vasomotor function. BAR correlates with invasive assessments of coronary endothelial function as well as multiple cardiovascular risk factors.

    Measured: %FMD after 6 weeks of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Estradiol+MPA and Estradiol+Drospirenone in people with Cardiovascular Diseases, run by Brigham and Women's Hospital 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 6 inclusion and 15 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 12 Jul 2016. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 3 May 2013). 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?

Brachial Artery Reactivity % Flow Mediated Dilation (BAR %FMD) (time frame: %FMD after 6 weeks of treatment). 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 12 Jul 2016.
