Additional Information

Official title Multicenter, Randomised, Double-blind, Placebo-controlled, Parallel Group, Phase 2/3 Study to Compare the Efficacy and Safety of Masitinib
Description Masitinib is novel tyrosine kinase inhibitor that targets microglia and mast cells through inhibiting a limited number of kinases. Masitinib blocks microglia proliferation and activation, and mast cell-mediated degranulation, the release of cytotoxic substances that might further damage the motor nerves.
