Renovacor Reports Second Quarter 2022 Financial Results and Provides Corporate Update

REN-001 IND submission planned for the second half of 2022

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 reported financial results for the second quarter of 2022 and provided a corporate update.

“The progress achieved at Renovacor this quarter enabled us to advance and expand our pipeline of precision AAV gene therapies that target the underlying drivers of devastating cardiovascular diseases,” said Magdalene Cook, M.D., Chief Executive Officer of Renovacor. “Peer-reviewed data published in the prestigious Journal of American College of Cardiology: Basic to Translational Science showed what we believe are meaningful levels of cardiac transduction when REN-001 was delivered locally to the heart of pigs at doses less than 1e13 vg/kg. We are now working to build upon these data with an expected IND submission for REN-001 in the second half of this year, and subsequent initiation of a Phase I/II clinical study in BAG3-DCM patients.”

Dr. Cook continued, “In addition to the progress made with our lead candidate, we expanded our pipeline with a new research program, in collaboration with the University of Utah, targeting the three largest genetic segments of arrhythmogenic cardiomyopathy. ACM patients are in urgent need of therapies that can address the underlying biology of their debilitating disease, and we are thrilled to be collaborating with the University of Utah in these efforts. Looking ahead, we believe we are well-positioned with a pipeline of differentiated precision medicine programs and a strong team of experienced industry veterans at all levels of the company.”

Second Quarter 2022 and Recent Highlights

• Continued Advancement of REN-001 Investigational New Drug (IND)-enabling Studies Supports Planned IND Submission in the Second Half of 2022: Planned IND submission is expected to enable the subsequent initiation of a Phase I/II clinical trial in BAG3-associated dilated cardiomyopathy (BAG3-DCM).

• Announced the Peer-reviewed Publication of Data from a Pilot Pig Study Showing Robust, Diffuse Cardiac Transduction with REN-001 Delivered via Low-dose Retrograde Coronary Sinus Infusion (RCSI): In the pilot study featured in a paper, which was published in Journal of the American College of Cardiology: Basic to Translational Science, low doses (<1e13 vector genome per kilogram) of REN-001 delivered locally to the heart of healthy Yucatan pigs using RCSI resulted in each cardiomyocyte containing, on average, at least one copy of the vector’s BAG3 payload (i.e., vector copy number threshold ≥1). Evaluation of cardiac tissue also showed diffuse transduction patterns across multiple regions of the heart and the presence of vector mRNA transcript. All evaluated animals tolerated the RCSI procedure without evidence of cardiac injury.

• Expanded Pipeline with New AAV Gene Therapy Research Program for Multiple Genetic Segments of Arrhythmogenic Cardiomyopathy (ACM): The program is being developed as a potential precision therapy for the three largest genetic segments of ACM: plakophilin-2 (PKP2), desmoglein-2 (DSG2), and desmoplakin (DSP) associated ACM. To accelerate this program, Renovacor entered into a research collaboration with the University of Utah’s Nora Eccles Harrison Cardiovascular Research and Training Institute (CVRTI). The research program aims to restore gap junction protein trafficking and gap junction communication between heart muscle cells to treat life-threatening arrhythmias associated with ACM. The terms of the research agreement grant Renovacor an option for an exclusive license to inventions generated from research conducted under the collaboration.

Second Quarter 2022 Financial Results

Net loss for the three months ended June 30, 2022 was $4.0 million, or $0.23 per basic and diluted share, compared to net loss of $3.7 million, or $0.59 per basic and diluted share, for the same period in 2021. Excluding non-cash gains totaling $5.1 million for the three months ended June 30, 2022 related to the change in fair value of our warrant and share earnout liabilities, net loss was $9.1 million, or $0.52 per basic and diluted share.

Research and development expenses were $6.3 million for the three months ended June 30, 2022, compared to $3.3 million for the same period in 2021.

General and administrative expenses were $2.8 million for the three months ended June 30, 2022, compared to $0.4 million for the same period in 2021.

Cash and cash equivalents as of June 30, 2022, totaled $62.0 million which, based on current projections, Renovacor believes will be sufficient to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2023.
