About this study

Current therapeutic options for a well-recognized group of patients with anginal symptoms-a positive exercise tolerance testing, SPECT or perfusion defect in MRI but angiographically normal coronary arteries-are limited. The condition, referred to as microvascular angina (MVA) or cardiac syndrome X, is not as benign as originally reported-patients presenting with unstable angina and nonobstructive atherosclerotic coronary artery disease have a 2% risk of death or myocardial infarction at 30 days of follow-up. It is more common in women in whom the first presentation of angina occurs either perimenopausally or postmenopausally. Aberrant flow-mediated coronary vasomotion is pivotal in the pathogenesis (systemic) impairment in endothelial function. Indeed, some centers use systemic assessments of vascular function in their diagnostic pathways for this group of women. It was recently suggested that endothelial dysfunction may lead to myocardial ischemia.

In the present study, the investigators tested the hypothesis that udenafil offers dual benefits of improving vascular function and lessening ischemia in women with angina, perfusion defect in cardiac MRI, and normal coronary arteries.

Read the detailed description

The aim of this study is that udenafil offers dual benefits of improving vascular function and lessening ischemia in women with microvascular angina, perfusion defect in cardiac MRI, and normal coronary arteries.

The UMPIRE trial is a multi-center, prospective, randomized, placebo controlled trial, designed to evaluate the effect of udenafil in improvement of myocardial stress perfusion defect in cardiac MRI, in women patients with microvascular angina. A total of 70 patients will be randomized to udenafil(100 mg q d) or placebo treatment. The primary end point of the study is Change of perfusion defect over 25% of baseline defect in adenosine-stress cardiac MRI after 3-month treatment. The secondary endpoints of this study are change of perfusion defect less than 25% of baseline defect in adenosine-stress cardiac MRI after 3-month treatment, decrement of frequency of chest pain, improvement of ST-depression in stress test, improvement of duke score in stress test, improvement of QoL assessment by SF-36 questionnaire, improvement of sexual dysfunction assessment by BISF-W self-questionnaire and improvement of biomarkers foe endothelial function.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Udenafil in people with Microvascular Angina, run by Samsung Medical Center at 2 sites in South Korea.

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 25 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: status not confirmed, as of the sponsor's last update on 26 Mar 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 South Korea. 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. 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 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Sung-Ji Park, M.D.,Ph.D. (82-2-3410-0887, tyche.park@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

to change of perfusion defect over 25% of baseline defect in adenosine-stress cardiac MRI after 3-month treatment. (time frame: baseline, 3 months after treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01769482, which also lists 1 linked publication.

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 26 Mar 2014.
