Masitinib

Drug Name: Masitinib
Company: AB Science
Location: France
Website: http://www.ab-science.com/
Drug Type: Small Molecule
Conditions: ALS, Alzheimer’s disease, multiple sclerosis, stroke, cancer, rheumatoid arthritis
Mechanism Type: Immunomodulation
Mechanism: Masitinib is thought to reduce inflammation in ALS by blocking microgliosis, at least in the spinal cord. (Trias et al., 2016). The drug may also help protect peripheral motor neurons in ALS by inhibiting the infiltration of macrophages and mast cells. Masitinib is an enzymatic inhibitor which blocks tyrosine kinases including CSF1R, c-Kit and PDGFRα/β.
U.S. Status for ALS: Phase III
