BrainStorm treatment shows good results in study

Thu May 29, 2008 4:04am EDT

May 29 - BrainStorm Cell Therapeutics Inc. (OTCBB:BCLI), a leading developer of adult stem cell technologies and therapeutics, announced today that in a pre-clinical study that was conducted with Tel Aviv University between February and May 2008, signs of impaired motor behavior in a rat model of Parkinson's improved following transplantation of BrainStorm's unique Neurotrophic Factor Cells (NTF).

"BrainStorm's NTF cells are generated from adult human bone marrow derived stem cells, and indented for autologous transplantation in Parkinson's patients. The cells produce and secrete neurotrophic factors, which are essential for the survival and outgrowth of neurons, and may become beneficial in neurodegenerative diseases," explains Dr. Daniel Offen, Brainstorm Chief Scientist, and the study's principal investigator.

In this study, Tel Aviv University scientists lesion the brains of lab rats by using the 6OHDA toxin, in order to mimic the motor dysfunction of parkinsonian patients. The rats were divided into three groups: one group was transplanted with BrainStorm NTF cells, another with undifferentiated mesenchymal stem cells and the third group was used as control.

The motor functions of the rats were repeatedly measured for 45 days, followed by histology. The results showed statistically significant improvement in NTF rats' motor functions, in compared to the mesenchymal cell group and the controls.

Moreover, the NTF cells increased the level of the neurotransmitter Dopamine (a low amount of which causes Parkinson). The researchers also detected, 45 days post-transplantation, viable transplanted cells which migrated toward the impaired portion of the affected brain.

The Company believes that this is evidence of the integration ability of BrainStorm's cells in the damaged brain. This is the second study completed using BrainStorm's cells that produced similar results.

Prof. Eldad Melamed, Chairman of the Company's Scientific Advisory Board and the Company's Chief Medical Advisor commented, "These exciting results provide validation of our previous scientific work. The study indicates that our cells show survival, integration and clinical efficacy.

"When considering the advantages of using adult stemcells, which are easy to harvest, autologous, do not create tumor problem and do not present the moral/ religious issues that are often discussed with embryonic stem cells, we remain optimistic that we will soon be able to embark on clinical trials in Parkinson's disease."

The legacy of Marie Schlau: literature to help cure Friedreich's Ataxia

If you feel like reading an unputdownable novel while collaborating with a just and solidary cause, "The Legacy of Marie Schlau" is your book! 100% of all funds raised will be dedicated to medical research to find a cure for Friedreich's Ataxia, a neurodegenerative disease that affects mostly young people, shortening their life expectancy and confining them to a wheelchair.

The life of Marie Schlau, a German Jewish girl born in 1833 hides great unsolved mysteries: accidents, disappearances, enigmas, unknown diagnoses, disturbing murders, love, tenderness, greed, lies, death ... alternatively a different story unfolds every time and takes us closer to the present. Thus, there are two parallel stories unravelling, each in a different age and place, which surprisingly converge in a revelatory chapter.

Research projects currently being financed by BabelFAmily

Currently, BabelFAmily is financing two promising research projects aimed at finding a cure for Friedreich's Ataxia. Whenever you make a donation to us or purchase a copy of "The legacy of Marie Schlau", this is where all funds raised will be devoted to:

1) Gene Therapy for Friedreich's Ataxia research project:

The project is the result of an initiative of Spanish people affected by this rare disease who are grouped in GENEFA in collaboration with the Spanish Federation of Ataxias and the BabelFAmily. The Friedreich’s Ataxia Research Alliance (FARA), one of the main patients’ associations in the United States now joins the endeavour.

2) Frataxin delivery research project:
The associations of patients and families Babel Family and the Asociación Granadina de la Ataxia de Friedreich (ASOGAF) channel 80,000 euros of their donations (50% from each organisation) into a new 18-month project at the Institute for Research in Biomedicine (IRB Barcelona). The project specifically aims to complete a step necessary in order to move towards a future frataxin replacement therapy for the brain, where the reduction of this protein causes the most damage in patients with Friedreich’s Ataxia.

The study is headed by Ernest Giralt, head of the Peptides and Proteins Lab, who has many years of experience and is a recognised expert in peptide chemistry and new systems of through which to delivery drugs to the brain, such as peptide shuttles—molecules that have the capacity to carry the drug across the barrier that surrounds and protects the brain. Since the lab started its relation with these patients’ associations in 2013*, it has been developing another two projects into Friedrich’s Ataxia.
