Bisoprolol in DMD Early Cardiomyopathy

September 27, 2022 updated by: Xiaoxiao Guo, Peking Union Medical College Hospital

Bisoprolol for Early Cardiomyopathy in Duchenne Muscular Dystrophy: a Randomized, Controlled Trial

This study aimed to use cardiac magnetic resonance imaging (CMR) to evaluate the efficacy and safety of bisoprolol therapy for boys with Duchenne muscular dystrophy(DMD) and preserved ejection fraction. On top of angiotensin-converting enzyme inhibitor (ACEI) , half of the participants will receive bisoprolol in combination, while the other half will not receive any beta-blocker.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

By the age of 20 years, almost all the patients with Duchenne muscular dystrophy(DMD) have experienced dilated cardiomyopathy (DCM), a condition that contributes significantly to their morbidity and mortality. Studies have shown ACEI to be an effective therapy for DMD boys with early cardiomyopathy. Although bisoprolol has been demonstrated as an effective neurohumoral drug for adult patients with DCM, few data exist concerning its safety and efficacy for the patients with DMD. The investigators hypothesize that the treatment with bisoprolol in addition to background ACEI therapy for 12 months in participants with DMD and early myocardial damage evident with late gadolinium enhancement and preserved ejection fraction, would blunt decline in left ventricular systolic performance.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: bisoprolol fumarate
In this arm, the participants will receive different dose of bisoprolol fumarate.
Drug: Bisoprolol Fumarate
Bisoprolol was initiated at a dose of 1.25 mg every 24hr. At subsequent biweekly visits, the bisoprolol dose was increased 1.25mg progressively until a daily dose of 0.2mg/kg or the maximum tolerated dose (The rest heart rate <75bpm and systolic blood pressure <90mmHg) is achieved. If the participant feel dizziness or the rest heart rate below 60 bpm or systolic blood pressure below 85mmHg or there is any new onset contraindication to bisoprolol, the doctor will decide to return back to the previous dose or stop bisoprolol. Each time the dose is increased, the medication is administered in an outpatient clinic setting, with assessment of the participant's heart rate, blood pressure, symptoms and ECG. Once reach the target dose, the patients will be followed up every 8 weeks in an face-to-face or video visit. After 12 months , the participants will repeat cardiac MR besides heart rate, blood pressure, symptoms, ECG and brain natriuretic peptide(BNP), echocardiography records.
No Intervention: Control
In the control (no beta blocker) group, the patients not taking beta blocker will receive outpatient clinic or video visit every 8 weeks and provide their cardiac symptoms, heart rate, blood pressure and ECG. After 12 months , the patients will repeat cardiac MR besides heart rate, blood pressure, symptoms, ECG,BNP and echocardiography records.
