Autologous cardiac-derived cells for advanced ischemic …

By raymumme

Disease Team Award DR1-01461, autologous cardiac-derived cells for advanced ischemic cardiomyopathy, is targeted at developing novel therapies for the treatment of heart failure, a condition which afflicts 7 million Americans. Heart failure, when symptomatic, has a mortality exceeding that of many malignant tumors; new therapies are desperately needed. In the second year of CIRM support, pivotal pre-clinical studies have been completed. We have found that dose-optimized injection of CSps preserves systolic function, attenuates remodeling, decreases scar size and increases viable myocardium in a porcine model of ischemic cardiomyopathy. The 3D microtissues engraft efficiently in preclinical models of heart failure, as expected from prior work indicating their complex multi-layer nature combining cardiac progenitors, supporting cells and derivatives into the cardiomyocyte and endothelial lineages. Analysis of the MRI data continues. We have developed standard operating procedures for cardiosphere manufacturing and release criteria, product and freezing/thawing stability testing have been completed for the 3D microtissue development candidate. We have identified two candidate potency assays for future development. The disease team will evaluate the results of the safety study (immunology, histology, and markers of ischemic injury) and complete the pivotal pig study in Q1 2012. With data in hand, full efforts will be placed on preparation of the IND for Q2 2012 submission.
