Adipose Stem Cell Heart Attack Trial Data Published in Journal of the American College of Cardiology; Cytori’s APOLLO Trial Demonstrated Safety & Feasibility and Improvements in Cardiac Function

Cytori Therapeutics announced today the publication of previously reported six-month outcomes from APOLLO, the Company’s European clinical trial evaluating adipose-derived stem and regenerative cells (ADRCs) in patients with acute myocardial infarction (heart attack or AMI), as Research Correspondence in the Journal of the American College of Cardiology. The APOLLO trial was a 14-patient, prospective, randomized, double-blind, placebo-controlled, feasibility trial (Phase I/IIA) evaluating autologous ADRCs extracted with the Company’s proprietary Celution® System for the treatment of patients suffering from acute myocardial infarction.

In the APOLLO trial all patients were treated with standard-of-care and subsequently underwent an abdominal liposuction. Each patient’s adipose tissue was processed by the Celution® System where ADRCs were extracted, washed and concentrated into a syringe of clinical grade cells. Within 36 hours of the myocardial infarction and no longer than 24 hours after undergoing percutaneous coronary intervention, patients received an injection of either 20 million ADRCs (n=10) or a placebo (n=4).

Scientists have taken the first steps toward producing the “heart patch,” a design for a medical implement used to repair damage from heart disease, a new study suggests.

Last week, researchers from Duke University presented the results of a study which, using mouse embryonic stem cells, examined the way these cells develop into heart muscle, HealthDay News reports (…)

Researchers at Queen Mary, University of London, studied equivalent cells taken from mouse brains. Principal investigator Silvia Marino, Professor of Neuropathology at Queen Mary, University of London, and her team showed that medulloblastomas can grow from a type of brain stem cell and that these cancers are a distinct form of the disease which may require a completely different approach to treatment.

DaVinci Biosciences LLC, of Costa Mesa, CA, announced today the presentation of their safety and feasibility study demonstrating the administration of autologous bone marrow derived stem cells for the treatment of acute and chronic spinal cord injury at Neuroscience 2009, Society for Neuroscience’s 39th Annual Meeting, to be held at McCormick Convention Center in Chicago, IL. Rafael Gonzalez, Ph.D., Director of Research and Development for DaVinci Biosciences LLC will present the work during the conference on October 20, 2009 and be available to answer questions regarding the study, following his presentation.

“We are excited to share the findings of this study in such a public forum. This study successfully demonstrates not only the safety and feasibility of using autologous adult stem cells for treating spinal cord injuries, but also that the clinical procedure for delivering these cells is safe as well,” said Dr. Gonzalez.

The abstract highlights data from 8 patients that underwent the treatment which used stem cells harvested from the patients’ own bone marrow to side step any immune rejection response, and features the documented evaluations from a 2 year post surgical follow up period. Furthermore, it illustrates new data obtained from 46 patients that participated in the study using stem cells harvested from the patients’ own bone marrow. Magnetic resonance imaging data of the spinal cord, obtained from those who were treated, shows morphological changes within the damaged areas. In addition, this study documents the improved function of bladder control, ASIA motor scoring and Barthel scoring.

“Although this study was successful, we will build upon the results that we have achieved and the methods we have developed to progress into a larger clinical program. Responsibly, but timely developing ways to improve the quality of life for those affected with injuries or diseases, such as spinal cord injury, is the core of our mission and we are optimistic about the opportunity of conducting future studies in the US,” said Dr. Gonzalez.

Neuralstem Inc. has received the green light to begin the first human stem cell trial to treat Amyotrophic Lateral Sclerosis (ALS), often referred to as Lou Gehrig’s disease. The company’s stock soared on the news.

Neuralstem has only received approval for the first stage of the trial that would consist of 12 patients who will receive stem cell injections in the lumbar area of the spinal cord.

Neuralstem said the trial will be under the direction of principal investigator Dr. Eva L. Feldman, Director of the University of Michigan Health System ALS Clinic and the Program for Neurology Research & Discovery. Feldman called the trial a major step forward in the treatment of ALS. “In work with animals, these spinal cord stem cells both protected at-risk motor neurons and made connections to the neurons controlling muscles. We don’t want to raise expectations unduly, but we believe these stem cells could produce similar results in patients with ALS,” Dr. Feldman said.

The drug metformin, a mainstay of diabetes care for 15 years, may have a new life as a cancer treatment, researchers said.
In a study in mice, low doses of the drug, combined with a widely used chemotherapy called doxorubicin, shrank breast-cancer tumors and prevented their recurrence more effectively than chemotherapy alone.

The findings add to a growing body of evidence that metformin, marketed as Glugophase by Bristol-Myers Squibb Co. and available in generic versions, could be a potent antitumor medicine.
They also lend support to an emerging theory that cancer’s ability to survive and resist therapy is regulated by cancer stem cells that drive a tumor’s growth and survival.

Chemotherapy is effective against many tumors, said Kevin Struhl, a Harvard Medical School researcher and principal investigator of the study. “The problem is cancer stem cells acquire resistance” to treatment, he said. “They are able to regenerate the tumor and as a result you end up with a relapse.”
About 5% to 10% of a tumor’s cells are believed to be cancer stem cells, he said.

In the report, being published in the Oct. 1 edition of Cancer Research, a journal of the American Association for Cancer Research, researchers said the combination of metformin and doxorubicin killed both regular cancer cells and cancer stem cells.
In contrast, doxorubicin alone had limited effect on the stem cells.
