Amyotrophic lateral sclerosis (ALS) is an adult onset neurodegenerative disorder characterized by the death of upper and lower motor neurons. About 10% of all ALS cases are familial, and we have identified SOD1 and FUS mutations as the most common causes in a consecutive series of 111 familial ALS pedigrees in Japan (Nishiyama A, 2017). From studies of the TDP43, FUS, and C9orf72 genes, perturbations of RNA processing can be highly adverse in motor neurons. Hepatocyte growth factor (HGF) is one of the most potent survival-promoting factors for motor neurons. We administered human recombinant HGF (hrHGF) by continuous intrathecal delivery to transgenic rats at onset of paralysis for 4 weeks. Intrathecal administration of hrHGF attenuated motor neuron degeneration and prolonged the duration of the disease by 63% (Ishigaki A, 2007). To translate this strategy to human treatment, we induced a contusive cervical spinal cord injury in the common marmoset, a primate, and then administered hrHGF intrathecally. We conducted a first-in-human phase I trial of intrathecal hrHGF in 15 Japanese patients with ALS (Warita H, 2019). Based on the results, we are conducting a phase II trial of intrathecal hrHGF for patients with ALS.
