Research collaboration with the University of Utah's Nora Eccles Harrison Cardiovascular Research and Training Institute expands pipeline with the addition of an AAV gene therapy program for multiple genetic segments of arrhythmogenic cardiomyopathy

CAMBRIDGE, MA -- Renovacor, Inc. (NYSE: RCOR), a biotechnology company focused on delivering innovative precision therapies to improve the lives of patients and families battling genetically-driven cardiovascular and mechanistically-related diseases, today announced it has expanded its pipeline to advance an AAV gene therapy program as a potential precision therapy for three genetic segments of arrhythmogenic cardiomyopathy (ACM). To accelerate this new program, Renovacor has entered into a research collaboration with the University of Utah’s Nora Eccles Harrison Cardiovascular Research and Training Institute (CVRTI). The terms of the research agreement grant Renovacor an option for an exclusive license to inventions generated from the collaboration.

The research collaboration will focus on a protein discovered by University of Utah scientists that has the potential to address multiple genetic segments of ACM. The new program is being developed as an AAV-based gene therapy to treat potentially life-threatening arrhythmias associated with the disease by restoring gap junction protein trafficking and gap junction communication between heart muscle cells. The program will be developed for the three largest genetic segments of ACM: plakophilin-2 (PKP2), desmoglein-2 (DSG2), and desmoplakin (DSP) associated ACM. Currently available treatment options do not address the trafficking defects central to each of these genetically-driven forms of ACM.

The collaboration leverages positive proof-of-concept data generated in a genetic mouse model of ACM that was performed by the Shaw Lab, led by Robin Shaw, M.D., Ph.D., Professor of Medicine at the University of Utah and Director of the CVRTI. These data demonstrate restoration of gap junction trafficking to the intercalated disc and a significant reduction in premature ventricular contractions (PVCs). PVCs are a hallmark of ACM and key drivers of potentially lethal ventricular arrhythmias.

“Renovacor’s pipeline expansion with this new AAV gene therapy research program for multiple genetic segments of ACM further demonstrates our precision medicine approach to develop potentially transformative therapies that target core biological drivers of serious cardiovascular diseases,” said Matt Killeen, Ph.D., Chief Scientific Officer of Renovacor.  “We believe we have found the ideal program and partner to leverage our expertise in heart muscle biology to discover and develop a novel gene therapy that could one day address a significant unmet medical need.”

“We are thrilled to have Renovacor as a partner to continue the research into these very important genetic drivers of ACM,” said Robin Shaw, M.D., Ph.D., Director of the CVRTI. “ACM is a serious disease of heart muscle that can lead to life-threatening, intractable arrhythmias. The team at Renovacor are experts in the understanding the importance of heart muscle biology, which makes them the ideal development partner to advance a novel, precision medicine approach for ACM. By seeking to understand and address a key causal disease pathway in ACM, together we hope to develop a therapeutic that could help improve the lives of patients who are living with this serious form of cardiomyopathy.”

Arrhythmogenic cardiomyopathy (ACM) is a heritable heart muscle disorder that can affect the left and right ventricle. It is characterized by a heightened risk of potentially lethal ventricular arrhythmias, fibrofatty replacement of myocardial tissue, and in some patients, heart failure.(1,2) It is recognized as a disease of the desmosome, with well-defined genetic drivers. The prevalence of ACM is estimated to range from 1 case in 1,000 persons to 1 case in 5,000, with an average age of diagnosis of approximately 30 years.(1-3) Current treatment options aim to prevent potentially life-threatening arrhythmias and progression to end-stage disease, but they do not target the underlying genetics or disease biology and, as such, patients can continue to experience serious breakthrough events.(1-2)
