What this trial studies

This Phase 2 clinical trial investigates the safety, tolerability, pharmacokinetics, and pharmacodynamics of CRD-4730 in adults diagnosed with Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT). Participants will be randomly assigned to receive two different doses of CRD-4730 and a placebo in a double-blind manner. The study aims to assess the drug's effectiveness in managing symptoms associated with CPVT through a multicenter approach. Each participant will undergo a series of evaluations to monitor their response to the treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a confirmed diagnosis of CPVT based on genetic screening.

Not a fit: Patients with clinically significant structural heart disease or recent history of myocardial infarction may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of CPVT, reducing the risk of life-threatening arrhythmias.

How similar studies have performed: While there have been studies on CPVT treatments, the specific approach using CRD-4730 is novel and has not been extensively tested.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

1. Males or Females ≥18 years of age, at screening.
2. Confirmed CPVT diagnosis, based on genetic screening for a known RyR2 mutation and a clinical phenotype consistent with CPVT at screening.
3. The participant can perform an EST during which frequent premature ventricular contraction (PVCs) (≥10 per minute), ventricular bigeminy, or higher-grade VA (equivalent to a VA score ≥2) are identified by the investigator.
4. Stable doses of any anti-arrhythmic medication, except amiodarone, for 4 weeks prior to screening.
5. Adhere to all contraceptive criteria.

Exclusion Criteria:

1. Clinically significant structural heart disease, diagnosis of heart failure, or clinically significant coronary artery disease.
2. History of a myocardial infarction, cerebrovascular accident, or transient ischemic attack within 3 months of screening.
3. History of malignancy within the past 5 years at screening (except successfully treated basal cell carcinoma or non-metastatic squamous cell carcinoma of the skin or cervical carcinoma in situ).
4. Female participant that is pregnant or lactating/ breastfeeding, or has plans to do so during the study or within 3 months following last dose of study drug.
5. Use of amiodarone with 3 months prior to screening. NOTE: other protocol defined Inclusion/ Exclusion criteria may apply.
