About this study

Official title: Heart Failure in Congenital Heart Disease: the Role of Myocardial Fibrosis. Treatment Sub-Study: Spironolactone vs. Placebo

The purpose of this study is to see if the study drug called spironolactone reduces fibrous (stiffening) in heart muscle tissue and improves heart function. Subjects from the study titled "Heart Failure in Congenital Heart Disease: the role of myocardial fibrosis" who have evidence of heart dysfunction and/or evidence of fibrosis (stiffening) in the heart muscle will be asked to take part in this study.

Read the detailed description

This study will include randomizing the subject to receive the study drug or placebo. Randomization will occur during visit 1.

Visit 1 will include the following:

  • Subjects will answer questions about how well they can breathe.
  • An MRI. Dye called gadolinium will be injected into the subject's vein.
  • They will go to the Oregon Clinical and Translational Research Institute where 2 tablespoons of blood will be drawn from an intravenous (IV) catheter (tube).
  • They will do a 6 minute walk test..
  • They will also have an echocardiogram, which is a test that looks at the movement of the subject's heart. A technician will place a cool jelly on their chest and use a small wand to take pictures through the skin.

Subjects' will also have visits 3-6 weeks, 3, 6, 9 months, and 12 months after randomization. Visits 2-5 will include the following:

  • They will go to the Oregon Clinical and Translational Research Institute where 1/2 tablespoon of blood will be drawn.
  • They will do a 6 minute walk test. During this test, they will walk back and forth in a hallway. The goal is to walk as far as possible for 6 minutes. Subjects will probably get out of breath or become exhausted. If they do, they can slow down, stop, or rest as they need to. Blood pressure will be taken before the walk.
  • They will have a health review at 6 months.

Visit 6 will be identical to visit 1 and include the following:

  • Subjects will answer questions about how well they can breathe.
  • An MRI. Dye called gadolinium will be injected into the subject's vein.
  • They will go to the Oregon Clinical and Translational Research Institute where 2 tablespoons of blood will be drawn from an intravenous (IV) catheter (tube).
  • They will do a 6 minute walk test..
  • They will also have an echocardiogram, which is a test that looks at the movement of the subject's heart. A technician will place a cool jelly on their chest and use a small wand to take pictures through the skin.

The investigators will compare the study drug, called spironolactone, to placebo with regard to any changes in heart stiffening and function of the heart.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Spironolactone 25mg in people with Congenital Heart Disease and Heart Failure, run by Oregon Health and Science University 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 7 inclusion and 8 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 21 Aug 2019. 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. 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 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 21 Aug 2019). 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?

Extracellular Volume Fraction (time frame: 12 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 21 Aug 2019.
