October 8, 2014 updated by: Corimmun GmbH

COR-1, an Anti-Beta1 Receptor Antibody Cyclopeptide in Heart Failure: a Phase II, Multicentre, Randomised, Double-Blind and Placebo-Controlled Study With Parallel Groups

The purpose of this study is to investigate the effect of COR-1 in combination with standard therapy in patients with heart failure. The safety and tolerability of COR-1 will also be assessed.

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

Detailed Description

In patients with dilated cardiomyopathy (heart is weakened and enlarged), the presence of anti-beta1-receptor autoantibodies has been shown to predict more depressed left ventricular function, increased prevalence of serious ventricular arrhythmias, sudden cardiac death, and cardiovascular mortality. In animal models, COR-1 cyclopeptide has been shown to bind to, and therefore decrease, the anti-beta1-receptor autoantibody titre. This study will investigate the safety and effectiveness of COR-1 treatment in patients with dilated cardiomyopathy. This study will be a randomized (the study treatment is assigned by chance), double-blind, (neither investigator nor patient knows the treatment that the volunteer receives), multicenter (study is conducted in more than one center) placebo-controlled (one of the treatments is inactive), parallel group study (patients in different treatment groups receive medication at the same time) in men and women who have heart failure due to dilated cardiomyopathy. Eligible patients should also have a left ventricular ejection fraction of less than or equal to 45% (measurement of the percentage of blood leaving the heart each time it contracts) and should be positive for anti-beta1-receptor autoantibodies. The study will consist of 3 phases: a screening phase, a double-blind treatment period, and a follow-up phase. Patients will be randomly assigned to 1 of 4 treatment groups: 20 mg COR-1, 80 mg COR-1, 160 mg COR-1, or placebo (inactive medication). Each patient will receive 1 intravenous dose (medication is injected into a vein) every 4 weeks for a total of 6 months. Patients will come to the study center each time they receive study medication and will remain at the center for 2 to 3 hours following the injection. Blood samples will be drawn at time points during the screening, treatment, and follow-up periods. Patients will return to the study center for follow-up visits at 3 months following completion of the 6-month treatment period. Patients will participate in the study for approximately 9 months. Patient safety will be monitored. The study drug (COR-1) is being investigated for the treatment of heart failure.

Phase

Phase

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Left Ventricular Ejection Fraction (LVEF) at Month 6
Time Frame: Baseline and Month 6
The LVEF is a fraction of blood (in percent) pumped out of the left ventricle of the heart (the main pumping chamber). Ejection fraction percentages greater than (>) 55% are considered normal. It was measured by biplane echocardiography (central assessment).
Baseline and Month 6

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Local Left Ventricular Ejection Fraction (LVEF) at Month 9
Time Frame: Baseline and Month 9
The LVEF is a measure of how much blood is pumped out of the left ventricle of the heart (the main pumping chamber). Ejection fraction percentages greater than (>) 55% are considered normal. It was measured by biplane echocardiography (local assessment).
Baseline and Month 9
Change From Baseline in N-Terminal Pro B-Type Natriuretic Peptide (NT-ProBNP) Level at Month 6
Time Frame: Baseline and Month 6
The NT-ProBNP is a biomarker (a biologic molecule) that has been shown to predict cardiac events.
Baseline and Month 6
Change From Baseline in Central Transmitral Flow Velocity Time Integral (VTI) at Month 6
Time Frame: Baseline and Month 6
Transmitral flow VTI measures how blood flows through the heart. This was measured by echocardiogram. Most of the values for transmitral flow VTI were not provided in the reports from central core echocardiographic laboratory due to technical reasons.
Baseline and Month 6
Change From Baseline in Central Tissue E-Wave Doppler Mitral Annular Velocity at Month 6
Time Frame: Baseline and Month 6
Tissue doppler mitral annular velocity is a measure of how well the heart fills with blood. This was measured by echocardiogram. Most of the values for E-wave were not provided in the reports from central core echocardiographic laboratory due to technical reasons.
Baseline and Month 6
Change From Baseline in Distance Walked During Six-minute Walk Test at Month 6
Time Frame: Baseline and Month 6
A standardized 6-minute walk test was performed and the distance covered in 6 minutes was measured.
Baseline and Month 6
Number of Participants With New York Heart Association (NYHA) Classification of Disease Progression
Time Frame: Baseline and Month 6
Disease progression (morbidity) was measured by the NYHA classification. The NYHA classification assesses the severity of symptoms of heart failure as judged by the investigator and is comprised of 4 stages. Stage I- No symptoms/limitation in ordinary physical activity (for example, shortness of breath when walking, climbing stairs); Stage II-Mild symptoms (mild shortness of breath and/or angina) and slight limitation during ordinary activity; Stage III- Marked limitation in activity due to symptoms, even during less-than-ordinary activity, (for example, walking short distances [20-100 m]), comfortable only at rest; and Stage IV- Severe limitations in activity/experiences symptoms while at rest (mostly bedbound participants).
Baseline and Month 6
Change From Baseline in Minnesota Living With Heart Failure Questionnaire Score at Month 6
Time Frame: Baseline and Month 6
Minnesota living with heart failure questionnaire is a self-administered, disease-specific measure of health related quality of life (QOL) that assesses participant's perceptions of the influence of heart failure on physical, socioeconomic and psychological aspects of life. Participants responded to 21 items using a six-point response scale (0-5). The total summary score can range from 0-105 with a lower score reflecting better heart failure related QOL.
Baseline and Month 6
Change From Baseline in Holter Electrocardiography (ECG) Parameters (Heart Rate) at Month 6
