Israeli biotechnology company Kadimastem has announced that it has approached the FDA regarding the cellular treatment it is developing for ALS. This is the initial approach the company is making to the FDA. In the framework of talks with the FDA, Kadimastem intends to consolidate a preliminary outline for its continuing trials for this indication.

Recently, the company reported positive results in a pre-clinical trial it conducted. In the trial, the efficacy of injecting support cells (astrocytes), produced by the company in a unique technology, into the spinal fluid of ALS model mice, was tested. This model is highly significant in predicting the treatment’s activity in humans.


The results of the trial showed an increased life expectancy in the mice treated, as well as a significant improvement of their motor (muscle) function, compared to the untreated mice. The efficacy of the treatment was also demonstrated in other indices indicating a delay in disease onset. Injections into the spinal fluid are standard procedure performed routinely in hospitals around the world. The company found that injections into the spinal fluid enable the even dispersion of cells throughout the central nervous system, thereby establishing the method of cell penetration in future treatment of patients.


Professor Michel Revel, the company’s chief scientist, notes, “This is an important step in the company’s progress towards the development of cellular therapy for ALS patients. Kadimastem is developing an industrial product, and is designing the cell production process while ensuring the required safety and reliability regulations. The early contact with the regulatory authorities is vital for the success of the development.”


Yossi Ben-Yossef, the company’s chief executive officer, notes, “Since the publishing of the initial results of the pre-clinical trial, we are operating to advance the process with the FDA. Upon receiving the FDA’s feedback, we will pursue the clinical development of cellular treatment for ALS.”
