About this study
Official title: Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist (TOPCAT)
The purpose of this study is to evaluate the effectiveness of aldosterone antagonist therapy in reducing cardiovascular mortality, aborted cardiac arrest, and heart failure hospitalization in patients who have heart failure with preserved systolic function.
Read the detailed description
BACKGROUND:
Heart failure (HF) is a major cause of morbidity and mortality, particularly in older people. Indeed, it is the most common discharge diagnosis in patients older than 65 years. As the United States population ages, heart failure will continue to grow as a public health concern. Therapeutic trials of heart failure have dealt almost exclusively with patients who have systolic dysfunction. However, there is now an emerging awareness that nearly half of the patients with heart failure have preserved systolic function and that the survival of these patients is adversely affected. This study is a randomized clinical trial of a novel therapeutic approach, specifically the use of spironolactone, an aldosterone antagonist, in treating these patients. While this treatment has been shown to be useful in treating heart failure with reduced systolic function, it has not been studied in patients with preserved systolic function.
Patients with heart failure and preserved systolic function have a poor prognosis. The annual mortality rate is intermediate between the prognosis for those without heart failure and for those with heart failure and reduced systolic function. For instance, Family Health Study participants with heart failure and preserved systolic function had a mortality rate of 9% compared to 3% for their age- and gender-matched controls. The mortality rate was 19% in heart failure patients with reduced systolic function heart failure compared to 4% for their matched controls.
As heart failure develops, neurohormones are released that initially improve cardiac output but ultimately contribute to progression of left ventricular dysfunction. The renin-angiotensin-aldosterone system is an important part of this compensatory response. Aldosterone levels may rise to 20 times normal levels in heart failure and aldosterone contributes to the development of myocardial fibrosis. Spironolactone is a potassium-sparing diuretic that acts on the distal tubule, inhibiting sodium and potassium ion exchange. There are several potential beneficial actions, including prevention of cardiac fibrosis. A recent trial evaluated spironolactone in patients with systolic dysfunction heart failure. Spironolactone treatment caused a 30% reduction in mortality compared to placebo (p< 0.001). The improvement resulted from a reduction in all cause mortality. More recently, the Eplerenone Post-Myocardial Infarction (MI) study showed that this aldosterone antagonist significantly reduces mortality despite background treatment with an angiotensin-converting enzyme (ACE) inhibitor and beta-blocker. Advantages of using spironolactone in this study are that it is commercially available, inexpensive, and no longer under patent (therefore this study will not be done by industry). Also, there is a clear physiologic rationale for its use, and the side effect profile is well understood. The study enrolled subjects who had preserved systolic function with heart failure and who met clearly defined eligibility criteria that were selected to make the results widely generalizable to clinical practice.
DESIGN NARRATIVE:
This is a randomized, double-blinded, placebo-controlled trial of aldosterone antagonist therapy (15 mg dose spironolactone or placebo; titrated up to 30 or 45 mg/day) in 3,445 adult patients with heart failure and preserved systolic function. Patients were recruited from August 2006 through January 2012, treated, and will be followed through June 2013. Approximately 270 clinical sites in six countries were subcontracted by the clinical trial coordinating center. Subject visits to a clinical center will occur every four or six months. Data collected include demographic and clinical data, including the results of history and physical exams, laboratory and imaging data, repository specimens for special physiology studies, and genetic studies. Additionally, data regarding quality of life and compliance with assigned treatment will also be collected and assessed.

Quality of Life, as Measured by the Kansas City Cardiomyopathy Questionnaire.
Average post-baseline quality of life, taking into consideration baseline quality of life, treatment group, the time between the post-baseline measures, and the correlation between repeated measures within an individual.
The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. Scores are transformed to a range of 0-100, in which higher scores reflect better health status. The KCCQ was administered at the following study visits: baseline, month 4, month 12 and annually thereafter.
Measured: Randomization through each subject's last semi-annual visit, up to a maximum of 6 years per subject.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to evaluate the effectiveness of aldosterone antagonist therapy in reducing cardiovascular mortality, aborted cardiac arrest, and heart failure hospitalization in patients who have heart failure with preserved systolic function.
Detailed description
BACKGROUND:
Heart failure (HF) is a major cause of morbidity and mortality, particularly in older people. Indeed, it is the most common discharge diagnosis in patients older than 65 years. As the United States population ages, heart failure will continue to grow as a public health concern. Therapeutic trials of heart failure have dealt almost exclusively with patients who have systolic dysfunction. However, there is now an emerging awareness that nearly half of the patients with heart failure have preserved systolic function and that the survival of these patients is adversely affected. This study is a randomized clinical trial of a novel therapeutic approach, specifically the use of spironolactone, an aldosterone antagonist, in treating these patients. While this treatment has been shown to be useful in treating heart failure with reduced systolic function, it has not been studied in patients with preserved systolic function.
Patients with heart failure and preserved systolic function have a poor prognosis. The annual mortality rate is intermediate between the prognosis for those without heart failure and for those with heart failure and reduced systolic function. For instance, Family Health Study participants with heart failure and preserved systolic function had a mortality rate of 9% compared to 3% for their age- and gender-matched controls. The mortality rate was 19% in heart failure patients with reduced systolic function heart failure compared to 4% for their matched controls.
As heart failure develops, neurohormones are released that initially improve cardiac output but ultimately contribute to progression of left ventricular dysfunction. The renin-angiotensin-aldosterone system is an important part of this compensatory response. Aldosterone levels may rise to 20 times normal levels in heart failure and aldosterone contributes to the development of myocardial fibrosis. Spironolactone is a potassium-sparing diuretic that acts on the distal tubule, inhibiting sodium and potassium ion exchange. There are several potential beneficial actions, including prevention of cardiac fibrosis. A recent trial evaluated spironolactone in patients with systolic dysfunction heart failure. Spironolactone treatment caused a 30% reduction in mortality compared to placebo (p< 0.001). The improvement resulted from a reduction in all cause mortality. More recently, the Eplerenone Post-Myocardial Infarction (MI) study showed that this aldosterone antagonist significantly reduces mortality despite background treatment with an angiotensin-converting enzyme (ACE) inhibitor and beta-blocker. Advantages of using spironolactone in this study are that it is commercially available, inexpensive, and no longer under patent (therefore this study will not be done by industry). Also, there is a clear physiologic rationale for its use, and the side effect profile is well understood. The study enrolled subjects who had preserved systolic function with heart failure and who met clearly defined eligibility criteria that were selected to make the results widely generalizable to clinical practice.
DESIGN NARRATIVE:
This is a randomized, double-blinded, placebo-controlled trial of aldosterone antagonist therapy (15 mg dose spironolactone or placebo; titrated up to 30 or 45 mg/day) in 3,445 adult patients with heart failure and preserved systolic function. Patients were recruited from August 2006 through January 2012, treated, and will be followed through June 2013. Approximately 270 clinical sites in six countries were subcontracted by the clinical trial coordinating center. Subject visits to a clinical center will occur every four or six months. Data collected include demographic and clinical data, including the results of history and physical exams, laboratory and imaging data, repository specimens for special physiology studies, and genetic studies. Additionally, data regarding quality of life and compliance with assigned treatment will also be collected and assessed.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Spironolactone in people with Cardiovascular Diseases and Heart Diseases, run by Carelon Research at 270 sites in 6 countries.
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 8 inclusion and 22 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 2 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 270 sites in United States, Russia, Canada, Argentina, Brazil and 1 more country. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 2 Mar 2015). 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?
Composite Outcome of Cardiovascular Mortality, Aborted Cardiac Arrest, or Hospitalization for the Management of Heart Failure, Whichever Occurred First (time frame: Randomization through each subject's last semi-annual visit, up to a maximum of 6 years per subject.). 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 NCT00094302, which also lists 80 linked publications.
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 2 Mar 2015.
