CAMBRIDGE, Mass., May 10, 2017 (GLOBE NEWSWIRE) -- Vericel Corporation (NASDAQ:VCEL), a leading developer of autologous expanded cell therapies for the treatment of patients with serious diseases and conditions, today announced that the U.S. Food and Drug Administration (FDA) has granted the Regenerative Medicine Advanced Therapy (RMAT) designation for ixmyelocel‑T, an investigational product for the treatment of patients with advanced heart failure due to ischemic dilated cardiomyopathy. The RMAT designation is a new expedited program established under the 21st Century Cures Act to foster the development and approval of regenerative medicine products intended for the treatment of serious diseases and conditions.
"Being among the first products to receive the RMAT designation, in addition to the recently granted Fast Track designation, highlights both the significance of the results from the ixmyelocel‑T Phase 2b ixCELL-DCM clinical study and the unmet medical need for improved therapies to treat advanced heart failure due to ischemic dilated cardiomyopathy," said Nick Colangelo, president and CEO of Vericel. "While our focus remains on our core commercial business, achieving the RMAT and Fast Track designations enhances the value of ixmyelocel-T to potential partners since they provide a pathway for expedited development and approval."
The RMAT designation is an expedited drug development and review program for regenerative medicine therapies. The purpose of the program is to get important new therapies for serious or life-threatening conditions to the patient earlier. A regenerative medicine is eligible for the designation if it is intended to treat, modify, reverse or cure a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug has the potential to address unmet medical needs for such a disease or condition.
In addition to providing an avenue for increased and earlier interactions with the FDA, designated products may be eligible for priority review and accelerated approval. As described in the 21st Century Cures Act, RMAT-designated products may be eligible for accelerated approval based on surrogate or intermediate endpoints reasonably likely to predict long-term clinical benefit, or reliance upon data obtained from a meaningful number of clinical sites. The sponsor of a regenerative advanced therapy that is granted accelerated approval and is subject to post-approval requirements may, as appropriate, fulfill such requirements through submission of clinical evidence, clinical studies, patient registries, or other sources of real world evidence such as electronic health records, through the collection of larger confirmatory datasets, or through post-approval monitoring of all patients treated with the therapy prior to approval.

About Advanced Heart Failure
Dilated cardiomyopathy (DCM), a progressive disease of the heart, is a leading cause of heart failure and heart transplantation. DCM is characterized by weakening of the heart muscle and enlargement of the heart chambers, leading to systolic abnormalities (difficulty of the left ventricle to pump blood). Heart enlargement and poor function generally lead to progressive heart failure with further decline in the ability of the heart to pump blood efficiently throughout the body. There is no cure for heart failure and there are limited treatment options in the advanced, refractory stage of the disease. Pharmacological interventions are typically introduced in earlier stages of heart failure and maximized as the condition progresses, with more invasive and aggressive interventions reserved for patients in later stages. By the time a patient progresses to the advanced stage of heart failure, they are being treated with multiple drugs with limited success for the treatment of persistent and severe symptoms, may have an implantable cardioverter‑defibrillator (ICD) or cardiac resynchronization therapy, and have few remaining treatment options (Yancy 2013).
Ixmyelocel-T is an investigational autologous expanded multicellular therapy manufactured from the patient's own bone marrow using Vericel's proprietary, highly automated, fully closed cell-processing system. This process selectively expands the population of mesenchymal stromal cells and alternatively activated macrophages, which are responsible for production of anti-inflammatory and pro-angiogenic factors known to be important for repair of damaged tissue. Ixmyelocel-T has been designated as an orphan drug by the U.S. Food and Drug Administration for use in the treatment of DCM.
About the ixCELL-DCM Trial
The ixCELL-DCM clinical trial was a multicenter, randomized, double-blind, placebo-controlled Phase 2b study designed to assess the efficacy, safety and tolerability of ixmyelocel-T compared to placebo when administered via transendocardial catheter-based injections to participants with end-stage heart failure due to ischemic DCM, who have no reasonable revascularization options (either surgical or percutaneous interventional) likely to provide clinical benefit. All participants were on maximized pharmacological heart failure treatment and had an automatic implantable cardiac defibrillator or cardiac resynchronization therapy (Henry 2016). The primary endpoint of the ixCELL-DCM clinical trial is the number of all-cause deaths, cardiovascular hospital admissions, and unplanned outpatient and emergency department visits to treat acute decompensated heart failure over the 12 months following administration of ixmyelocel-T compared to placebo. Primary endpoint results were presented in a late-breaking clinical trial session at the American College of Cardiology's (ACC) 65th Annual Scientific Session. The ixCELL-DCM trial met its primary endpoint with a 37% reduction in the composite endpoint, primarily driven by a reduction in all cause deaths and cardiovascular hospitalizations. In addition, this study showed internal consistency (ie, repeatability) in observable or "hard" efficacy endpoints of survival and cardiovascular hospitalizations (total number and time to events), reduction in ventricular arrhythmias, and safety results including major cardiac adverse events (MACE), serious adverse events (SAEs), deaths, and intravenous pharmacological treatment for heart failure (Patel 2016). Because the trial met the primary endpoint, patients who received placebo or were randomized to ixmyelocel‑T in the double-blind portion of the trial but did not receive ixmyelocel-T, have been offered the option to receive treatment with ixmyelocel‑T.
About Vericel Corporation
Vericel develops, manufactures, and markets autologous expanded cell therapies for the treatment of patients with serious diseases and conditions. The company markets three cell therapy products in the United States. Vericel is marketing MACI® (autologous cultured chondrocytes on porcine collagen membrane), an autologous cellularized scaffold product indicated for the repair of symptomatic, single or multiple full-thickness cartilage defects of the knee with or without bone involvement in adults. Carticel® (autologous cultured chondrocytes) is an autologous chondrocyte implant for the treatment of cartilage defects in the knee in patients who have had an inadequate response to a prior arthroscopic or other surgical repair procedure. Epicel® (cultured epidermal autografts) is a permanent skin replacement for the treatment of patients with deep dermal or full thickness burns greater than or equal to 30% of total body surface area. Vericel is also developing ixmyelocel‑T, an autologous multicellular therapy intended to treat advanced heart failure due to ischemic dilated cardiomyopathy (DCM).
