Frequently asked questions about RP-A601

What is RP-A601 used for in PKP2 Arrhythmogenic Cardiomyopathy?

RP-A601 is an investigational gene therapy being developed for PKP2 variant-mediated Arrhythmogenic Cardiomyopathy (PKP2-ACM), a cardiovascular condition. It is designed to address the genetic cause of the disease by delivering a functional PKP2 gene. RP-A601 is currently in Phase 1 clinical development and has not been approved by the FDA.

What does RP-A601 target?

RP-A601 targets the PKP2 gene, which encodes plakophilin-2, a protein essential for heart muscle cell adhesion and electrical signaling. By delivering a functional copy of the PKP2 gene, RP-A601 aims to correct the underlying genetic defect in patients with PKP2 variant-mediated Arrhythmogenic Cardiomyopathy. This gene therapy approach is being evaluated in a Phase 1 clinical trial.

Who makes RP-A601?

RP-A601 is being developed by Rocket Pharmaceuticals, Inc., a biopharmaceutical company traded on NASDAQ under the ticker RCKT. The company is conducting a Phase 1 clinical trial of RP-A601 in patients with PKP2 variant-mediated Arrhythmogenic Cardiomyopathy. The trial is currently recruiting participants in the United States.

What phase is RP-A601 in?

RP-A601 is in Phase 1 clinical development. It is an investigational gene therapy and has not received FDA approval. The drug has been granted Regenerative Medicine Advanced Therapy (RMAT) designation by the FDA, which is intended to expedite the development and review of regenerative medicine therapies for serious conditions.

What clinical trials is RP-A601 in?

RP-A601 is being studied in a single Phase 1 clinical trial with the identifier NCT05885412. This is a dose escalation trial enrolling approximately 9 adult patients with PKP2 variant-mediated Arrhythmogenic Cardiomyopathy. The trial is actively recruiting in the United States and is an open-label, uncontrolled study.

Is RP-A601 the same as PKP2 gene therapy?

RP-A601 is a gene therapy that targets the PKP2 gene, but it is not referred to by an alternative name in the available information. It is specifically designed to treat PKP2 variant-mediated Arrhythmogenic Cardiomyopathy by delivering a functional PKP2 gene. The drug is being developed by Rocket Pharmaceuticals under the name RP-A601.
