FDA Clearance Received for Heart Attack Stem Cell Clinical Trial
News May 04, 2007
Australia's adult stem cell company, Mesoblast Limited has announced that the United States Food and Drug Administration (US FDA) has cleared the Investigational New Drug Submission (IND) of its US-based sister company, Angioblast Systems Inc., to commence a Phase 2 clinical trial of its allogeneic, or 'off-the-shelf', adult stem cells for patients with heart attacks.
"FDA clearance is a significant step towards commercialising our stem cell products in the US, the world's largest market for cardiovascular diseases," said founder and Chief Scientific Adviser, Professor Silviu Itescu. "Importantly FDA clearance was obtained within 30 days of the submission of the IND," he said.
The Phase 2 clinical trial will be based at the Texas Heart Institute, and will follow a similar protocol to the one used by the same investigators in preclinical studies for the IND submission. These showed that implantation of the company's allogeneic stem cells by catheter into damaged heart muscle resulted in significant improvement in heart function and reduction in congestive heart failure.
According to Mesoblast, this clinical trial will be the first to test an allogeneic stem cell product injected by catheter into heart muscle damaged by a recent heart attack. The trial will use the latest generation catheters provided through Angioblast's ongoing relationship with the Johnson & Johnson companies, Cordis Corporation and Biosense Webster.
The commercial strategy for both Mesoblast and Angioblast is to generate high margin stem cell products that are obtained from a single donor, expanded, frozen, and subsequently used in thousands of unrelated, or allogeneic, recipients at the time and place of need.
The spatial and temporal dynamics of proteins or organelles plays a crucial role in controlling various cellular processes and in development of diseases. However, acute control of activity at distinct locations within a cell cannot be achieved. A new chemo-optogenetic method enables tunable, reversible, and rapid control of activity at multiple subcellular compartments within a living cell.
