XyloCor Therapeutics Presents Phase 2 Data Highlighting Safety and Efficacy of XC001 at the European Society of Cardiology (ESC) Congress 2023

• Positive Phase 2 EXACT Trial results at 6-months underscore significant potential of investigational therapy in refractory angina

• Six-month data have since been sustained out to 12-months supporting durability of XC001 safety and efficacy profile

• XC001 targets unmet medical need among patients with refractory angina who have a debilitating quality-of-life burden and no available treatment options

XyloCor Therapeutics, Inc., a clinical‑stage biopharmaceutical company developing novel gene therapies for cardiovascular disease, today presented results from the Phase 2 portion of its Phase 1/2 clinical trial (EXACT) of its lead gene therapy candidate XC001 (encoberminogene rezmadenovec) for refractory angina at the European Society of Cardiology (ESC) Congress 2023. During the ESC Congress poster session, Dr. Thomas Povsic, Principal Investigator of the EXACT trial, presented the primary six-month outcome data from the recently completed EXACT trial, which demonstrated that treatment with XC001 resulted in improvements across all key efficacy endpoints. The findings underscore its strong potential as a novel therapeutic approach for the treatment of this disabling condition.

XC001 is a one‑time gene therapy designed to reduce ischemic burden by creating new blood vessels in the heart through the local expression of multiple vascular endothelial growth factor (VEGF) isoforms. In the Phase 2 portion of the EXACT trial, 32 patients with class II-IV angina were dosed with the maximal dose of XC001 through transepicardial delivery (direct administration to the heart). XC001 met all of its safety and exploratory objectives and showed potential transformative benefits for the patient population. Among the notable topline results presented at the ESC Congress 2023 included:

• VEGF gene therapy with XC001 administered via minimally invasive transepicardial delivery was generally well tolerated.

• There were no serious adverse events related to the drug or unexpected serious adverse events related to XC001 administration.

• Patients demonstrated improvements in key efficacy measures most notably total exercise time, time to the development of ST-depression (an objective measure of ischemia), angina frequency, and reduction in ischemic burden as measured by Positron Emission Tomography (PET) imaging.

• The six-month results showed that XC001 achieved a clinically meaningful biologic effect, warranting further study in larger randomized clinical trials.

“Refractory angina is a debilitating and chronic condition that is growing in prevalence and these patients have exhausted all treatment options,” said Thomas Povsic, M.D., Ph.D., Professor of Medicine, Duke University School of Medicine and National Principal Investigator for the EXACT study. “The six-month results from the EXACT trial – which have now been sustained out to 12 months – demonstrate that gene therapy with XC001 has the potential to be safely administered while improving quality of life for these cardiac patients.”

“The clinical research results presented at ESC Congress 2023 highlight XyloCor's continuing efforts to transform the treatment paradigm in refractory angina through the promise of one-time gene therapy,” said Al Gianchetti, President and CEO of XyloCor. “We are excited to share data that provides evidence for angiogenesis and a promising efficacy and tolerability profile for XC001. These results strongly support our continued development of this novel therapeutic approach.”

About XC001

XC001 is designed to promote new blood vessels in the heart that will bypass diseased blood vessels and improve blood flow. By restoring blood flow, chest pain associated with refractory angina may decrease, potentially improving patients’ quality of life by enabling them to engage in daily physical activities that would otherwise cause pain. XC001 is designed to avoid toxicity issues observed with other gene therapies through a strategy of one‑time, local administration. This approach allows XC001 to achieve higher gene expression in the heart while minimizing systemic vector circulation and associated side effects.

About the EXACT Study

The Epicardial Delivery of XC001 Gene Therapy for Refractory Angina Coronary Treatment (EXACT) clinical trial was a Phase 1/2 multicenter, open‑label, single‑arm trial. Twelve subjects (n=3 per dose cohort) who have refractory angina were enrolled into four ascending dose groups, followed by an expansion phase of the trial in which additional subjects were enrolled at the highest tolerated dose (1 x 1011 vp, the highest tested dose). In the EXACT trial, this investigational gene therapy is administered directly to the heart muscle through a mini‑thoracotomy by a cardiac surgeon.

About Chronic Refractory Angina

In the United States, coronary artery disease is a leading cause of death and disability. Chronic angina pectoris occurs when the heart muscle does not receive sufficient oxygen resulting in chest pain. This is usually due to atherosclerotic plaques that block the coronary arteries. Refractory angina is a growing problem that occurs in patients with chronic angina who are symptomatic despite optimal medical therapy and are no longer eligible for mechanical interventions like percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). These patients currently have no treatment options and are frequently highly symptomatic, which severely impacts their quality of life, and may exacerbate comorbidities and cause further deterioration of their health status. Refractory angina results in significant consumption of healthcare resources, including visits to the emergency department as a result of patients’ chest pain.

Results from XyloCor Therapeutics’ Phase 1 Portion of EXACT Trial of XC001 for Cardiovascular Disease Published in Circulation: Cardiovascular Interventions

• Findings from the Phase 1 dose escalation portion of the EXACT trial of XC001 in refractory angina provided the dose selection and safety justification for the recently completed Phase 1/2 study

• XC001 is a one-time gene therapy candidate designed to reduce ischemic burden by creating new blood vessels in the heart through the local expression of multiple VEGF isoforms

• XyloCor is moving forward with urgency to address potential of XC001 as transformative therapy for patients with ischemic heart disease with significant unmet need

XyloCor Therapeutics, Inc., a clinical-stage biopharmaceutical company developing novel gene therapies for cardiovascular disease, announced today that Circulation: Cardiovascular Interventions has published results from the Phase 1 portion of its Phase 1/2 clinical trial (EXACT) of lead gene therapy candidate XC001 (encoberminogene rezmadenovec) in patients with refractory angina. The findings from the Phase 1 dose escalation study, previously reported at the American Association for Thoracic Surgery (AATS) and the American Society of Gene and Cell Therapy (ASGCT) in May 2022, revealed that XC001 is well tolerated at all dose levels and provided justification to proceed to Phase 2 with the highest dose tested.

“The results from the Phase 1 study provided the mechanistic underpinning that was the catalyst for the successful completion of the Phase 2 EXACT trial,” said Thomas Povsic, M.D., Ph.D., lead author of the journal article, Professor of Medicine, Duke University School of Medicine and National Principal Investigator for the EXACT study. “Patients with refractory angina are highly symptomatic and have an exceedingly poor quality of life. With a robust body of positive and sustained safety and efficacy out to 12 months from the EXACT trial, we believe that XC001 has the potential to fill the significant unmet need for this patient population who currently lack treatment options.”

"We are thrilled with the publication of these EXACT trial results in Circulation: Cardiovascular Interventions, a highly-regarded and influential international journal for cardiovascular research," said Howard Dittrich, Chief Medical Officer of XyloCor. “We would like to acknowledge all of the authors for their contributions in highlighting the promise of XC001 and thank patients and their families for their participation in the EXACT trial. Our team is singularly focused on continuing to unlock the transformative potential of XC001 for improving outcomes in cardiovascular disease.”

The Phase 1 portion of the Phase 1/2 EXACT study was a first-in-human, multicenter, open-label, single-arm, dose-escalation study to evaluate the safety, tolerability, and preliminary efficacy of increasing doses of XC001, and to establish the best dose to carry forward for additional study in Phase 2. Twelve patients were enrolled into four dosing cohorts. Notably, the study demonstrated that adenoviral vector doses higher than those used in previous studies were well tolerated and more robust efficacy was demonstrated at the higher doses. This established a dose of 1×1011 viral particles for future clinical research of XC001.

XyloCor Therapeutics Reports Positive Topline Safety and Efficacy Results from Phase 2 EXACT Clinical Trial of XC001 Novel Gene Therapy for Refractory Angina

• No serious adverse events related to drug product were reported

• Patients demonstrated improvements in exercise capacity and reductions in episodes of chest pain

• Cardiac imaging results provide mechanistic evidence supporting the therapeutic potential of XC001 in cardiovascular disease

XyloCor Therapeutics, a clinical-stage biopharmaceutical company developing novel gene therapies for cardiovascular disease, today announced completion of the Phase 2 portion of its Phase 1/2 clinical trial (EXACT) designed to assess the safety and preliminary evidence of efficacy of lead gene therapy candidate XC001 (encoberminogene rezmadenovec) in patients with refractory angina. EXACT met both safety and efficacy objectives. There were no safety issues related to drug product or unexpected serious adverse events related to XC001 administration. Six-month data from 28 patients in the Phase 2 portion of the study showed improvements in several key efficacy measures, including reduction in ischemic burden.

“We are excited to see EXACT completing its 6-month endpoint. The trial met all of its safety and exploratory objectives, showing intriguing benefits in these needy patients across a variety of objective and subjective measures,” said Thomas Povsic, M.D., Ph.D., Professor of Medicine, Duke University School of Medicine and National Principal Investigator for the EXACT study. “The strong range of mechanistic evidence demonstrate that administration of XC001 is a scientifically-sound approach for achieving a biological effect that has the potential to improve patients’ quality of life.”

XC001 is a one-time gene therapy designed to reduce ischemic burden by creating new blood vessels in the heart.

XyloCor Therapeutics, a clinical-stage biopharmaceutical company developing novel gene therapies for cardiovascular disease, today announced the completion of the Phase 1 dose-escalation component of its Phase 1/2 clinical trial (EXACT) of XC001 (encoberminogene rezmadenovec), its lead investigational gene therapy candidate for patients with refractory angina who have no further treatment options.

Following a review of clinical data from the Phase 1 dose escalation component of the study, the Independent Data Monitoring Committee (IDMC) authorized proceeding to the Phase 2 component of the study at the highest dose tested. Since the IDMC authorization, three patients have been dosed in the Phase 2 expansion cohort. This progress highlights the potential for gene therapy to go beyond rare diseases and to address larger patient populations with significant unmet needs, such as chronic cardiovascular diseases.

XyloCor also confirms that it plans to submit an additional Phase 2 clinical study to the U.S. Food and Drug Administration (FDA) for XC001 as adjunctive therapy to coronary artery bypass grafting (CABG) in 2H21. The company also plans other clinical studies in additional cardiovascular indications, including heart failure caused by ischemic heart disease and as adjunctive therapy to percutaneous coronary intervention.

“Patients with refractory angina are forced to live with the ongoing burden of a disease that limits their activities on a daily basis due to chest pain,” said Thomas Povsic, M.D., Ph.D., Duke University cardiologist and National Principal Investigator for the EXACT study. “With a unique mechanism of action that restores blood flow to the heart via the creation of new blood vessels, XC001 represents a novel therapeutic approach for patients who have exhausted other medical and surgical options. It is very exciting to now move forward with exploring XC001’s potential in the Phase 2 portion of EXACT as a one-time therapy for patients with refractory angina.”

“In our mission to deliver safe and effective gene therapies that transform the lives of people with cardiovascular disease, we are excited to achieve this important milestone and advance into the Phase 2 portion of our study,” said Al Gianchetti, President and Chief Executive Officer of XyloCor Therapeutics. “XC001 has enormous potential to significantly improve the lives of patients with refractory angina. We are grateful for the support of patients and their families, as well as the EXACT trial investigators as we continue to study the safety and efficacy of XC001 and look forward to reporting results in 2022.”

About XC001

XC001 (encoberminogene rezmadenovec) is a novel, investigational gene therapy designed to stimulate the growth of new blood vessels in the heart, in order to bypass diseased vessels and improve coronary blood flow. XC001 delivers the gene for vascular endothelial growth factor (VEGF), a naturally occurring protein, in targeted myocardial cells, thus stimulating the creation of new blood vessels via a process called angiogenesis. XC001 employs a proprietary multi-isoform VEGF expression cassette that has been optimized to maximize expression of VEGF. XC001 has been granted Fast Track designation by the FDA for study in refractory angina. XyloCor commenced the EXACT Trial, a Phase 1/2 study of XC001 in chronic refractory angina, in 2020.

About the EXACT Study

The Epicardial Delivery of XC001 Gene Therapy for Refractory Angina Coronary Treatment (EXACT) clinical trial is a Phase 1/2 multicenter, open-label, single-arm, dose-escalation trial. 12 subjects (n=3 per dose cohort) who have refractory angina were enrolled into four ascending dose groups, to be followed by an expansion phase of the trial with 21 additional subjects at the highest tolerated dose. The trial is designed to assess the preliminary safety and efficacy of XC001. The investigational gene therapy is administered directly to the heart muscle through a mini-thoracotomy by an experienced cardiac surgeon. The EXACT Trial is being conducted at top cardiovascular research sites across the United States.

About Chronic Refractory Angina

In the United States, coronary artery disease is a leading cause of death and disability. Chronic angina pectoris occurs when the heart muscle does not receive sufficient oxygen resulting in chest pain. This is usually due to atherosclerotic plaques that block the coronary arteries. Refractory angina is a growing problem that occurs in patients with chronic angina who are symptomatic despite optimal medical therapy and are no longer eligible for mechanical interventions like percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). These patients currently have no treatment options and are frequently highly symptomatic, which severely impacts their quality of life, and may exacerbate comorbidities and cause further deterioration of their health status. Refractory angina results in significant consumption of healthcare resources, including visits to the emergency department as a result of patients’ chest pain. An estimated one million people suffer from refractory angina in the United States.

XyloCor Therapeutics Completes Oversubscribed $41.9 Million Series A Financing To Advance Novel Gene Therapy Pipeline For Coronary Artery Disease

• Company closes additional $22.6 million in new financing 

• Proceeds will fund initiation of new clinical trial for lead gene therapy candidate XC001 as adjunctive therapy for patients undergoing coronary artery bypass graft surgery 

XyloCor Therapeutics, a private clinical-stage biopharmaceutical company focused on the development of gene therapy for the significant unmet patient needs in advanced coronary artery disease, today announced the closing of an additional $22.6 million financing. Fountain Healthcare Partners led the oversubscribed financing joined by new investors Longwood Fund and Lumira Ventures. All existing institutional investors including Sofinnova Investments and LSP (Life Sciences Partners) participated in the financing. The additional financing builds upon XyloCor’s 2018 Series A financing round, bringing total investment in the company to $41.9 million to date. XyloCor’s lead product candidate, XC001, is an investigational gene therapy currently being studied in a Phase 1/2 clinical trial (EXACT) for patients with refractory angina, a chronic condition for which there are no treatment options.

The financing will enable XyloCor to expand its clinical development program for XC001, including the initiation of a new trial of XC001 as a potential adjunctive therapy to augment the effectiveness of coronary artery bypass graft surgery (CABG). XyloCor is at the forefront of scientific research and clinical study in the application of gene therapy to address vast unmet treatment needs in large patient populations with cardiovascular disease. In both its initial potential indication in refractory angina, and as an adjunctive therapy for patients undergoing CABG, XC001 represents a novel therapeutic approach.

“We greatly appreciate the recognition by Fountain Healthcare Partners, Longwood Fund, and Lumira Ventures of the value we have created since our initial funding and in XC001’s enormous potential for improving the lives of patients with advanced coronary disease,” said Al Gianchetti, president and chief executive officer of XyloCor Therapeutics. “With the support of our investors, we can build on the progress we have made since our initial funding to pursue, with a sense of urgency, new clinical indications where XC001 has promise for addressing unmet medical needs.”

“XyloCor has created significant value with XC001 with the progress the team has achieved on clinical and CMC milestones. Based on our experience, excellence on both fronts is critical to success in the gene therapy field,” said Aidan King, managing partner and co-founder, Fountain Healthcare Partners, who also joined XyloCor’s board of directors. “We are gratified that this additional capital accelerates XC001’s development and expands its potential impact to the significant unmet need among CABG patients who are at high risk for incomplete revascularization.”

Board of Directors Additions

Joining Mr. King as a member of the XyloCor board of directors is Daniel Hétu, M.D., managing director, Lumira Ventures, and Perry Nisen, M.D., Ph.D., executive partner, Sofinnova Investments. Alan Colowick, M.D., MPH, will now serve an independent board member of XyloCor.

About XC001

XC001 is an investigational gene therapy designed to promote the growth of new blood vessels in the heart, with these new blood vessels bypassing diseased blood vessels and improving blood flow in the heart. XC001 deposits the gene for vascular endothelial growth factor (VEGF) in targeted heart cells. VEGF is a naturally occurring protein and it is believed that XC001 enables the heart cells to produce more VEGF, thus stimulating the creation of new blood vessels, a process called angiogenesis. XC001 has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for study in refractory angina. An Investigational New Drug (IND) application for XC001 is open with the FDA. XyloCor commenced the EXACT Trial, a Phase 1/2 study of XC001 in chronic refractory angina in 2020.

The EXACT Trial

The EXACT clinical trial is a Phase 1/2 multicenter, open-label, single arm, dose escalation trial. Approximately 12 subjects (n=3 per cohort) who have refractory angina will be enrolled into 4 ascending dose groups, followed by an expansion phase of the trial with 21 additional subjects at the highest tolerated dose. The trial is designed to assess the safety and efficacy of XC001. The investigational gene therapy will be administered directly to the muscle tissue of the heart by an experienced cardiac surgeon. The EXACT Trial was initiated in 2020 and is ongoing at top cardiovascular research sites across the United States.

About Chronic Refractory Angina

Chronic angina pectoris occurs when the heart muscle does not receive as much oxygen as it needs for the amount of work it is performing, and this often results in chest pain. This is usually due to coronary artery disease. Patients with chronic angina who are symptomatic despite optimal medical therapy and are no longer eligible for mechanical interventions like percutaneous coronary intervention (PCI) and CABG have refractory angina and currently have no treatment options. These patients often become sedentary because of their symptoms, which in turn can exacerbate comorbidities and severely impact quality of life causing further deterioration of their health status. An estimated one million people suffer from refractory angina in the United States.

About Coronary Artery Bypass Graft Surgery (CABG)

CABG is a procedure used to treat coronary artery disease – the narrowing or blockage of the blood vessels that supply oxygen and nutrients to the heart muscle. During CABG, a healthy artery or vein from the body is connected, or grafted, to the blocked coronary artery. The grafted artery or vein bypasses the blocked portion of the coronary artery. This creates a new passage, and oxygen-rich blood is routed around the blockage to the heart muscle. Approximately 500,000 CABG procedures are performed annually in the United States, in which an estimated one-third of patients are at risk for incomplete coronary revascularization, often resulting in persistent angina. An adjunctive treatment to CABG, such as gene therapy with XC001, may reduce the incidence of incomplete revascularization.
