AB Science SA (Euronext - FR0010557264 - AB) today announced that an abstract on the long-term survival of masitinib in amyotrophic lateral sclerosis (ALS) has been selected for a platform presentation at the Annual Meeting of the Spanish Society of Neurology, which will be held in virtual format between November 22 and December 2, 2021.

This abstract has received the honor of being designated as an extended ’ comunicaciónoralestelar (stellar oral communication). During this event, which will be held in Spanish, latest advances in the neurological field will be presented with more than 3,000 national and international experts expected to connect.


The presentation, titled ’ Long-term survival analysis of masitinib in amyotrophic lateral sclerosis’, will be delivered by Professor Josep Gamez M.D., Ph.D. (Director of the Peripheral Nervous System Laboratory and Head of the Neuromuscular Disorders Clinic at the Vall d’Hebron Research Institute, Barcelona, Spain), a senior investigator from the masitinib phase 2/3 study (AB10015) in ALS [1].

Professor Gamez said, “ Selection of this abstract for acomunicaciónoralestelarat theSpanish Society of Neurology LXXIII Annual Meetingis an indication of the level of interest being generated bylong-term survival data frommasitinibstudy AB10015. Wefirstsuspected thatmasitinibmaygenerateimproved survivalincertainsubgroupsthroughobservation ofpatientsenrolled in study AB10015 at theValld’HebronHospital’s ALS Unit[2]. Findings from the overall study long-term survival analysishave confirmed this impression using a larger, multicenter patient cohort, whichalsorevealedthat there is a greater treatment effect when masitinib is initiated at an earlier stage of disease[3] ”.

About amyotrophic lateral sclerosis
Amyotrophic lateral sclerosis (ALS) is a fatal motor neuron disorder that is characterized by progressive loss of the upper and lower motor neurons at the spinal or bulbar level. The disease belongs to a group of disorders known as motor neuron diseases, which are characterized by the gradual degeneration and death of motor neurons. In ALS, both the upper motor neurons and the lower motor neurons degenerate or die, and stop sending messages to muscles.
The prevalence of ALS in western countries is fairly uniform at 6 per 100,000 persons, corresponding to around 30,000 cases in Europe and 20,000 in the USA.
The first drug treatment for ALS, riluzole (Rilutek), was approved in 1995. In Europe, there has been no new treatment approved since riluzole.

About masitinib
Masitinib is an 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.
