About AMO-02

AMO-02 (tideglusib) is in development for the treatment of congenital myotonic dystrophy and has potential for use in additional CNS, neuromuscular and oncology indications. AM0-02 is positioned to enter clinical stage development for the treatment of the severe form of congenital myotonic dystrophy known as DM1 or Steinert disease. In cellular and animal models of DM1 and Duchenne muscular dystrophy, as well as in muscle biopsies from patients, activity of glycogen synthase kinase 3 beta (GSK3ß) has been shown to increase. Inhibitors of GSK3ß have been shown to correct the activity of regulatory proteins, such as CUGBP1 in animal models of DM1. AMO-02 is an inhibitor of GSK3ß that has demonstrated pre-clinical efficacy in transgenic models and reversal of muscle cell deficits in ex vivo tissue samples in patients with DM1.

Inhibition of increased levels of GSK3ß is known to reverse cognitive and behavioral deficits in transgenic models of syndromic autism, a developmental disorder characterized by social communication deficits and repetitive behaviors.
