Hypertrophic Cardiomyopathy (HCM) is the most common inherited heart muscle condition affecting up to 1 in 200 of the general population. It results from mutations in genes encoding components of the contractile apparatus in the heart muscle cell (myocyte). Read more about this study

About this study

Official title: Randomised Controlled Trial of pErhexiline on regreSsion Of Left Ventricular hypErtrophy (LVH) in Patients With Symptomatic Hypertrophic CardioMyopathy (RESOLVE-HCM)

Hypertrophic Cardiomyopathy (HCM) is the most common inherited heart muscle condition affecting up to 1 in 200 of the general population. It results from mutations in genes encoding components of the contractile apparatus in the heart muscle cell (myocyte). These mutations result in increased energy cost of force production for the myocyte which then cumulatively causes a myocardial energy deficit. This myocardial energy deficit is then thought to lead to cardiac hypertrophy ('left ventricular hypertrophy' or LVH) in HCM.

LVH leads to impairments in heart muscle function, heart muscle oxygenation and microvascular blood flow and is the chief driver of patient symptoms in HCM. These symptoms consist of chest pain, shortness of breath, dizziness, fainting episodes or palpitations. Occasionally, the disease may cause sudden cardiac death (SCD). HCM is the most common cause of SCD in young people including competitive athletes. In addition, HCM has been found to result in significant global deterioration in health-related quality of life.

Treatment of HCM has focused on relief of symptoms by drugs such as ß-blockers which slow the heart rate and improve heart function. However, symptom relief is often incomplete and there is no evidence on the benefit of ß-blockers or related medications to reverse LVH. Perhexiline, a potent carnitine palmitoyl transferase-1 (CPT-1) inhibitor shifts myocardial metabolism to more efficient glucose utilisation and rectifies impaired myocardial energetics. It is currently used to treat angina in patients with coronary artery disease. There is some preliminary evidence that Perhexiline may aid in the improvement of symptoms in patients with HCM. However, the effect of any form of therapy on potential regression of LVH in HCM remains unexplored.

In this randomised double-blind placebo-controlled trial, the investigators will use state of the art cardiac imaging, principally advanced echocardiography and Cardiovascular Magnetic Resonance (CMR) to study the effects of perhexiline on LVH, cardiac function, and oxygenation in symptomatic patients with HCM. The investigators hypothesize that perhexiline will favourably reduce LVH and improve myocardial oxygenation by improving myocardial energetics, and that these putative morphological and functional changes can be accurately measured utilizing echocardiography and CMR. If this pilot study supports the hypothesis, then it will pave the way for a major randomised controlled trial to definitely determine the role of Perhexiline in HCM.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PerhexilineDrug

    Also called Pexsig

    All eligible and consented patients will be randomised to initiation of perhexiline 100mg once daily or identical placebo. After 4 days of treatment, a blood sample will be collected to determine plasma perhexiline concentrations: timing of the sample need not be "trough" in view of the long-acting nature of perhexiline. Depending on the blood results, patients might require as little as 50mg/week (slow metabolisers) or as much as 600mg/day (ultra-rapid metabolisers). The initial sample will be utilized primarily to detect presence of hydroxylated metabolite: patients in whom perhexiline is detected in the absence of metabolite will be designated "slow metabolisers" and will have their dosage reduced to 50 mg/week in the first instance. Repeat assay at 30 days will be utilized for individual finer dose titration based on dose adjustment table. Paired dosage adjustment in placebo-treated patients will be performed to avoid unblinding.

    Compliance will be assessed by capsule count.

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 10 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 11 Mar 2021. 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 Australia. 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.

Results are not available in the source record.

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

Contact Joseph Selvanayagam (+61882045619, joseph.selva@sa.gov.au), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Left Ventricular Hypertrophy (LVH) (time frame: 12 months post baseline). 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 11 Mar 2021.
