New preclinical data demonstrate that masitinib has an unexpected protective effect on muscles and nerves in amyotrophic lateral sclerosis (ALS)
AB Science SA (NYSE Euronext - FR0010557264 - AB), a pharmaceutical company specialized in the research, development and marketing of protein kinase inhibitors (PKIs), announces today that new mechanistic data demonstrate the unexpected protective effect of masitinib on muscles and nerves in amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. These new data have been presented at the 27 th International Symposium on ALS/MND in December 2016 in Dublin, Ireland.
These new data complete the following previous findings:
Professor Luis Barbeito (Head of the Neurodegeneration Laboratory, Institut Pasteur in Montevideo, Uruguay), delivered a presentation at the 27 th International Symposium on ALS/MND (December 2016, Dublin, Ireland). This meeting is the largest medical and scientific conference specific to ALS and is the premier event in the ALS research calendar for discussion on the latest advances in research and clinical management.
Professor Luis Barbeito said "Beyond our recently published findings 1 , we have acquired additional preclinical data showing neuroprotective effects of masitinib in ALS. We have now shown that masitinib generates its observed neuroprotective effect in ALS by regulating neuroinflammation in the peripheral nervous system as well as the central nervous systems, and that it also penetrates the blood-brain-barrier to a greater extent than previously thought. Overall, these data provide further compelling pharmacological rationale for the recently reported positive phase 3 interim analysis 2 ."
Below is the summary of new preclinical findings presented at the meeting that support the use of masitinib is ALS:
New data show protective effects of masitinib in the peripheral nervous system of SOD1 G93A (ALS) rats in a therapeutic setting (after paralysis onset).
Masitinib has been shown to generate protective effects in the sciatic nerve:
Masitinib has been shown to generate protective effects at the neuromuscular junction (NMJ). It is at the NMJ that the nerve fiber is able to transmit a signal to the muscle fiber, causing muscle contraction:

About Amyotrophic Lateral Sclerosis
Amyotrophic lateral sclerosis is a rare degenerative disorder that results in progressive wasting and paralysis of voluntary muscles. There are approximately 50,000 people with ALS in the European Union and in the US, with more than 16,000 new cases diagnosed each year in Europe and in the US. Almost 80% of ALS patients die within 5 years and 90% die within 10 years.
About masitinib
Masitinib is a new orally administered tyrosine kinase inhibitor that targets mast cells and macrophages, important cells for immunity, through inhibiting a limited number of kinases. Based on its unique mechanism of action, masitinib can be developed in a large number of conditions in oncology, in inflammatory diseases, and in certain diseases of the central nervous system. In oncology due to its immunotherapy effect, masitinib can have an effect on survival, alone or in combination with chemotherapy. Through its activity on mast cells and microglia and consequently the inhibition of the activation of the inflammatory process, masitinib can have an effect on the symptoms associated with some inflammatory and central nervous system diseases and the degeneration of these diseases.
