Chronic Heart Failure Trial Using Mesoblast’s, Receives FDA Clearance


NBN Infusions delivers comprehensive services to patients of all ages, from pediatric to geriatric, providing a full range of care for Home Infusion Therapy. NBN Infusions on-site, licensed pharmacy can provide prescription medications, equipment, supplies and skilled nursing care needed for Home Infusion Therapy.

Home Infusion Therapy is a more convenient and cost-effective option than traditional inpatient therapy, with care administered in the comfortable surroundings of one’s own home. Home Infusion Therapy allows for a more active role in one’s own health care. It can also ease stress and anxiety that is sometimes associated with inpatient treatment, resulting in better patient outcomes.


Mesoblast Limited’s development and commercial partner Teva Pharmaceuticals Industries Ltd has received the United States Food and Drug Administration (FDA clearance to begin phase III trial in patients with chronic congestive heart failure using Mesoblast’s proprietary Mesenchymal Precursor Cells (MPCs). The IND was cleared by the FDA within the minimum 30-day period following submission, and patient recruitment is expected to begin shortly.


The multi-centre trial, which will be conducted by Teva, is planned to enrol approximately 1,700 patients and includes two interim analyses of efficacy and/or safety. The clinical protocol was designed after initial consultation with both the FDA and the European Medicines Agency.


The phase II trial design is a double-blinded, 1:1 randomized, placebo-controlled study evaluating a single dose of 150 million MPCs delivered via transendocardial injection catheter to the left ventricle of heart failure patients with New York Heart Association (NYHA) class II or III disease and an ejection fraction = 40%. The primary efficacy endpoint of the trial is a time-to-first event analysis of heart failure-related Major Adverse Cardiac Events (HF-MACE), defined as a composite of cardiac related death or resuscitated cardiac death, or non-fatal decompensated heart failure events. These nonfatal decompensated heart failure events require use of intravenous diuretics or aquapheresis during an in-hospital stay or during an outpatient visit. Adjudication of HF-MACE will be performed by an independent, blinded clinical endpoint committee.


The MPC dose for the phase III trial was chosen on the basis of results from a 60-patient phase II trial which has shown that heart failure patients treated with the 150 million MPC dose have not experienced any HF-MACE over the three-year follow-up period compared with an HF-MACE incidence of approximately 30 per cent for the control group over the same period.


Mesoblast chief executive Silviu Itescu said: “We believe that Mesoblast’s proprietary mesenchymal lineage cells have the potential to offer long-term beneficial outcomes to the millions of patients suffering from heart failure worldwide. Importantly, in 2014 we plan to have products in active phase III clinical trials in all four of our core major therapeutic areas of focus: cardiovascular medicine (congestive heart failure), inflammatory/immune diseases (Crohn’s disease), orthopedics (spinal fusion and intervertebral disc repair) and oncology (acute Graft versus Host Disease, and cord blood expansion in bone marrow transplantation).”


Mesoblast Limited is a world leader in the development of biologic products for the broad field of regenerative medicine.
