简要总结
This is a prospective, multi-center, randomized, controlled, patient- and evaluator-blinded study comparing treatment with the CardiAMP cell therapy to a sham control treatment. A roll-in phase with a maximum of 10 subjects may occur.
详细描述
Heart failure is a clinical condition in which the output of blood from the heart is insufficient to meet the metabolic demands of the body. In 2015, the American Heart Association, or AHA, report on heart disease statistics estimated that there are 5.7 million Americans over the age of 20 that have heart failure. Heart failure is increasingly prevalent due to the aging population and the increase in major cardiovascular risk factors, including obesity and diabetes.
The AHA also estimates that one in five adults will develop heart failure after the age of 40. During heart failure progression, the heart steadily loses its ability to respond to increased metabolic demand, and mild exercise soon exceeds the heart's ability to maintain adequate output. Towards the end stage of the disease, the heart cannot pump enough blood to meet the body's needs at rest. At this stage, fluids accumulate in the extremities or in the lungs making the patient bedridden and unable to perform the activities of daily living. The long-term prognosis associated with heart failure is approximately 50% mortality at five years following the initial diagnosis.
CardiAMP cell therapy is a comprehensive therapeutic treatment that comprises (i) a point of care cell processing platform and (ii) a biotherapeutic delivery system. CardiAMP cell therapy is the first comprehensive therapeutic treatment utilizing a patient's own cells for the treatment of ischemic heart failure with reduced ejection fraction. In the screening process, the physician extracts a small sample of the patient's bone marrow in an outpatient procedure performed under local anesthesia. The clinic sends the sample to a central diagnostic lab, which tests the sample. For the study treatment, a clinician collects and then prepares the patient's own bone marrow mononuclear cells, or autologous cells, using the CardiAMP point of care cell processing platform, which a cardiologist then delivers into the heart using the Helix biotherapeutic delivery system.
BioCardia intends to submit data obtained from this clinical trial in a Pre-Market Approval Application to the United States Food and Drug Administration
