Advanced Cell Technology and Catholic Healthcare West Sign Clinical Agreement.

Catholic Healthcare West to Become Advanced Cell Technology's First Clinical Trial Site for Phase II Myoblast Study

LOS ANGELES -- Advanced Cell Technology, Inc. (ACT) (OTCBB: ACTC) announced today that it has signed a clinical trial agreement with Chandler Regional Medical Center and Mercy Gilbert Medical Center, members of Catholic Healthcare West (CHW), the nation's eighth largest healthcare system, to become ACT's first clinical trial sites for the Phase II myoblast study. In addition, CHW has received Institutional Review Board approval for the clinical trial, which is expected to begin soon. ACT's myoblast program is an autologous adult stem cell therapy for the treatment of heart disease that has successfully completed four Phase I clinical trials and received clearance from the Food and Drug Administration to begin Phase II trials.

In November 2007, ACT and CHW announced that the two parties had entered into a letter of intent for a proposed exclusive business arrangement to establish a clinical trial research site and a North American regenerative medicine interventional cardiology training center for the Phase II clinical trial. The study, which will utilize 3-Dimensional Guided Catheter-Based Delivery of Autologous Skeletal Myoblasts for Ishemic Cardiomyopathy (CAuSMIC), will soon be open for enrollment. Led by principal investigator Nabil Dib, M.D., M.Sc., F.A.C.C., director of Cardiovascular Research for Chandler Regional Medical Center and Mercy Gilbert Medical Center, enrollment in the CAuSMIC trial will focus on patients who are not eligible for angioplasty or coronary artery bypass surgery, and who continue to have poor quality of life despite receiving optimal medical therapy or cardiac resynchronization therapy with a pacemaker or defibrillator device.

"The agreement with CHW signifies our readiness to begin the Phase II clinical trial," said William M. Caldwell, IV, chairman and CEO of ACT. "We are excited to begin the trial, which has the potential to be a major advance for the field of regenerative medicine and, more importantly, to patients in need of care. We look forward to working with such a prominent healthcare group."

"Currently, there are no treatment options available to correct heart failure, only those that can slow its progression," said David G. Covert, president and CEO of the CHW East Valley Service Area and Chandler Regional Medical Center. According to Covert, Dr. Dib's findings are the culmination of seven years of prior clinical work to demonstrate the safety and utility of taking a patient's own muscle stem cells to repair heart muscle damage. "Chandler Regional Medical Center and Mercy Gilbert Medical Center are proud to participate in developing this innovative treatment option for people living with heart failure. As we continue to develop our research program, our main focus is to translate this type of research into bedside standard of care."
