Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 89 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Systolic blood pressure >140 mmHg, diastolic blood pressure > 90 mmHg.
  • An elevated left ventricular mass index (defined as >60 g/m1.7 in women and 80 g/m1.7 in men) OR LV posterior wall thickness >1.4 cm documented in a clinically indicated echocardiographic examination or magnetic resonance imaging scan within the previous 12 months.
  • Stable medical therapy as defined by: (1)No addition or removal of ACE inhibitors, angiotensin receptor blockers, beta-blockers, or calcium channel blockers for 30 days. (2)No change in dosage of ACE, angiotensin-receptor blocker, beta-blockers or calcium-channel blockers s of more than 100% for 30 days.
  • Current therapy with an ACE inhibitor, hydralazine or a statin, all of which have been shown to reduce nitrate tolerance.

Who cannot join

  • Rhythm other than sinus rhythm (i.e., atrial fibrillation).
  • Non-cardiac condition limiting life expectancy to less than one year, per physician judgment.
  • Current or anticipated future need for nitrate therapy.
  • Valve disease (> mild aortic or mitral stenosis; > moderate aortic or mitral regurgitation).
  • Hypertrophic cardiomyopathy.
  • Known infiltrative or inflammatory myocardial disease (amyloid, sarcoid).
Show all 18Show fewer
  • Pericardial disease.
  • Primary pulmonary arteriopathy.
  • Have experienced a myocardial infarction or unstable angina, or have undergone percutaneous transluminal coronary angiography (PTCA) or coronary artery bypass grafting (CABG) within 60 days prior to consent, or requires either PTCA or CABG at the time of consent.
  • Resting heart rate (HR) > 100 bpm.
  • A reduced LV ejection fraction (EF<50%).
  • Known severe liver disease (AST > 3x normal, alkaline phosphatase or bilirubin > 2x normal).
  • Patients with a clinically indicated stress test demonstrating significant ischemia within a year of enrollment which was not followed by percutaneous or surgical revascularization.
  • Allergy to isosorbide mononitrate.
  • Current therapy with phosphodiesterase inhibitors, such as sildenafil, vardenafil or tadalafil, since the combination of nitrates and phosphodiesterase inhibitors can result in severe hypotension.
  • Therapy with rosiglitazone, since this combination is not recommended based on epidemiologic data suggesting that it may increase the risk of myocardial ischemia.
  • Current pregnancy or a positive urine pregnancy test. Women who become pregnant during the study will be discontinued from the trial.
  • Contraindications to a cardiac MRI: (i) Central nervous system aneurysm clips; (ii) Implanted neural stimulators; (iii) Implanted cardiac pacemaker or defibrillator; (iv) Cochlear implant; (v) Ocular foreign body (e.g. metal shavings); (vi) Other implanted medical devices: (e.g. drug infusion ports); (vii) Insulin pump; (viii) Metal shrapnel or bullet; (ix) Claustrophobia; (x) Extreme obesity rendering the patient unable to fit into narrow-bore scanners; (xi) Unwillingness of the patient to undergo a cardiac MRI. All patients with metallic implants will be individually evaluated prior to MRI.

About this study

Official title: Targeting Wave Reflections to Improve Left Ventricular Hypertrophy, Fibrosis and Myocardial Function in Hypertension

The purpose of this research study is to test whether treatment with isosorbide mononitrate will improve left ventricular hypertrophy ("thickening") which puts people at risk for developing heart failure. Once it develops, heart failure is a very serious condition and thus it is important to find ways to prevent it from happening. The investigators have reasons to believe that dilating the blood vessels with this specific medication will improve the thickening of the heart, which increases the risk of heart failure.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Isosorbide Mononitrate, sustained release in people with Hypertension, run by Corporal Michael J. Crescenz VA Medical Center 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 4 inclusion and 18 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: withdrawn, as of the sponsor's last update on 11 Aug 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. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Change in left ventricular mass (time frame: 24 weeks). 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 NCT01961453, which also lists 2 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 11 Aug 2016.
