About this study

Official title: ENavogliflozin DElivering Alleviation of Ventricular Diastolic Dysfunction in nonObstRuctive Hypertrophic CardioMyopathy: a Prospective, Multicenter, Randomized, Double-blind, Placebo-controlled Study (ENDEAVOR-HCM)

The primary objective of this study is to investigate the effect of enavogliflozin, an Sodium-glucose transporter 2 (SGLT2) inhibitor, compared with placebo on left ventricular diastolic function in patients with nonobstructive hypertrophic cardiomyopathy. The secondary objective of this study is to investigate the effect of enavogliflozin on exercise capacity, symptoms, serum biomarkers, and arrhythmic burden in patients with nonobstructive hypertrophic cardiomyopathy.

Read the detailed description

Most of the medication used in HCM(hypertrophic cardiomyopathy) targets dynamic left ventricular obstruction and hypercontractility. Guidelines recommend that beta-blockers and calcum channels can also be used to lower heart rate and improve diastolic function in symptomatic nonobstructive HCM(hypertrophic cardiomyopathy), and that diuretics may be considered next, but there is a paucity of evidence supporting these recommendations. Left ventricular diastolic dysfunction is the main pathophysiological mechanism in nonobstructive HCM. SGLT2(Sodium-glucose transporter 2) inhibitors have been shown to reduce heart failure events and mortality in patients with heart failure with preserved ejection fraction, and have also been reported to improve left ventricular diastolic function. This study will investigate the efficacy and safety of enavogliflozin, an SGLT2(Sodium-glucose transporter 2) inhibitor, compared with placebo in patients with nonobstructive hypertrophic cardiomyopathy, over a period of 6 months.

Patients with hypertrophic cardiomyopathy and without evidence of dynamic left ventricular outflow tract obstruction at resting or on provocation by Valsalva maneuver or exercise will be enrolled. Participants will be randomly assigned to the enavogliflozin 0.3mg group and the placebo group in a 1:1 ratio and will continue the medication for 24 weeks. Changes in left ventricular diastolic reserve assessed by diastolic stress echocardiography will be compared between the treatment groups at 24 weeks. Changes in other parameters of diastolic function and exercise capacity will be assessed by diastolic stress echocardiography and compared between the treatment groups. Symptom status, serum biomarker levels, and arrhythmic burden on 24 hour ambulatory electrocardiogram will also be compared between the treatment groups. Post-trial follow-up will be performed at 52 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing enavogliflozin 0.3mg in people with Nonobstructive Hypertrophic Cardiomyopathy, run by Yonsei University at 1 site 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 9 inclusion and 17 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: looking for participants now, as of the sponsor's last update on 8 Nov 2024. 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 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?

This study is still under way. Results are not available in the source record yet.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in left ventricular diastolic reserve (Δe') assessed by diastolic stress echocardiography (time frame: 24 weeks, 52 weeks). 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 8 Nov 2024.
