Trial Summary

What is the purpose of this trial?

The goal of this clinical trial is to test IC14 (atibuclimab) in patients with arrhythmogenic cardiomyopathy (ACM) and who have an implantable cardoverter/defibrillator in place. ACM is also called arrhythmogenic right ventricular dysplasia (ARV) or arrhythmogenic right ventricular cardiomyopathy (ARVC). The main questions the study aims to answer are the effect of treatment on blood markers of inflammation, safety, and pharmacokinetics. There will also be measurements of myocardial imaging of C-C chemokine receptor type 2 (CCR2+) immune cells (optional), monitoring of cardiac arrhythmias using the patient's pre-existing intracardiac cardioverter/defibrillator (ICD) and a Holter monitor, electrocardiogram (ECG), echocardiogram (ECHO), and blood tests. Results will be compared to baseline; there is no inactive placebo treatment group. Participants will be asked to undergo screening and baseline testing, then receive 4 intravenous infusions with blood measurements before and after the infusion (including 24, 48, and 72 hours and 7, 14, and 28 days). Participants will be offered specialized scanning of the heart muscle, and will be asked to provide recordings from their ICD, undergo Holter monitoring twice, and have electrocardiograms (ECG), echocardiograms (ECHO) and blood tests.

Will I have to stop taking my current medications?

The trial requires that you do not change your current medications for arrhythmogenic cardiomyopathy unless it's necessary for managing life-threatening conditions.

Eligibility Criteria

This trial is for patients with arrhythmogenic cardiomyopathy (ACM), a heart muscle disease that can cause irregular heartbeats. Participants must have an implantable cardioverter/defibrillator (ICD) already in place.

Inclusion Criteria

C-reactive protein ≥1.5 mg/mL

I have had a serious irregular heartbeat or more than 500 early heartbeats in a day.

I am a male who hasn't had a vasectomy and will use contraception for 30 days after treatment.

Exclusion Criteria

I am currently on a continuous antiarrhythmic medication infusion.

My liver and kidney functions are normal, and my liver enzymes are not three times above the normal limit.

I have not had major blood vessel surgery in the last 4 weeks.

Treatment Details

Interventions

• IC14 (Monoclonal Antibodies)

Trial Overview The trial tests IC14 (atibuclimab), focusing on its effects on inflammation markers, safety, and how the body processes it. It includes blood tests, heart scans, and monitoring of heart rhythms using existing ICDs and additional devices.

Participant Groups

Group I: IC14 (atibuclimab) Experimental Treatment 1 Intervention

IC14 (atibuclimab) 20 mg/kg intravenously every 3 weeks for 12 weeks (4 doses)
