Unique cell therapy company NeoStem's (AMEX:NBS) Progenitor Cell Therapy (PCT) unit Tuesday was named as the contract manufacturer for a Baxter International (NYSE:BAX) Phase III stem cell trial.
Tuesday started a phase III pivotal clinical trial to evaluate the
efficacy and safety of an individual's own CD34+ stem cells to increase
exercise capacity in patients with chronic myocardial ischemia (CMI), a
coronary artery disease.
CMI is one of the most severe forms of
coronary artery disease, causing significant long-term damage to the
heart muscle and disability to the patient. It is often diagnosed based
on symptoms of severe, refractory angina, which is severe chest
discomfort that does not respond to conventional medical management or

therapy is typically more expensive, requiring thousands of dollars to
manufacture an individual cell therapy. Baxter has announced 450
patients for its trial.
It may take the pharmaceutical giant a
few years to enroll all of these patients. The primary endpoint measured
at the 12 month follow up is a patient's total exercise capacity.
added: "We are very excited to see the results of the phase III data
when published as the phase II trial provided evidence that leveraging
the body's own natural repair mechanisms can improve exercise capacity
and reduce chest pain."
Baxter is taking a slightly different approach in its CMI therapy, opting to inject cells directly into the heart.
AMR-01 therapy is different in that the cells they use are not injected
into the heart muscle. These cells are infused into the infarct-related
artery and mobilize to the area of injury where they are needed," Smith

has issued U.S. patents that broadly cover the use of stem cells for
the treatment of vascular injury caused by vascular insufficiency. The
company believes these patents cover any commercially viable use of stem
cells for the repair of vascular injury resulting from any ischemic
event, including, for example, acute myocardial infarction (AMI).

effective amount of a chemotactic hematopoietic stem cell product; the
product includes a cellular component containing a population of
autologous mononuclear cells from any source enriched for CD34 cells,
where the CD34 cells contain a subpopulation of biologically active
CD34+/CXCR-4+ cells that, when delivered by catheter whenever needed,
can migrate in a directed fashion to areas of ischemic damage and effect
repair, and a serum component that maintains the biological activity of
these motile cells and enables commercial processing of the cells.
