AbstractAmyotrophic lateral sclerosis (ALS) is a devastating, fatal neuromuscular disease. Most patients die within 2 to 5 years of diagnosis. The disease stems from death of upper and lower motor neurons leading to degeneration of motor pathways and the paralytic effects of the disease. The economic cost of the disease is not clear, with estimates ranging from about $64,000 per year to $200,000. Two drugs, riluzole and edaravone, are currently FDA approved for the treatment of ALS, and each provides modest benefits in mortality and/or function. Recent developments in the understanding of the underlying pathophysiologic processes that contribute to ALS have led to the development of numerous investigational therapies, with several now in phase 3 trials. This article highlights the oral tyrosine kinase inhibitor masitinib; the antisense drug tofersen; the humanized monoclonal antibody C5 complement inhibitor ravulizumab-cwvz; and mesenchymal stem cell (MSC)-neurotrophic factor (NTF) cells, a proprietary platform that induces autologous bone marrow-derived MSCs to secrete high levels of NTFs.
