Therapeutic for other neurodegenerative disorders, including Welander distal myopathy (WDM), a rare autosomal dominant disorder caused by a missense mutation in the human TIA1 gene. Small molecules penetrate the CNS and pass through cell membranes (unlike main competitors, which are antibody-based). Most current anti-tau therapies in development are immunotherapies, which have thus far been ineffective, in large part because of poor antibody penetration into the CNS and poor membrane permeability.
