Description: XPC-6444 is a highly potent inhibitors of NaV1.6 with high selectivity over NaV1.1 and NaV1.5. XPC-6444 provided excellent anticonvulsant activity and reduced seizure activity in a dose-dependent manner in an induced seizure model, which utilized SCN8A GOF mice carrying the N1768D mutation identified in a human EIEE13 patient.

Additional Information

Nonselective antagonists of voltage-gated sodium (NaV) channels have been long used for the treatment of epilepsies. The efficacy of these drugs is thought to be due to the block of sodium channels on excitatory neurons, primarily NaV1.6 and NaV1.2. However, these currently marketed drugs require high drug exposure and suffer from narrow therapeutic indices. Selective inhibition of NaV1.6, while sparing NaV1.1, is anticipated to provide a more effective and better tolerated treatment for epilepsies. In addition, block of NaV1.2 may complement the anticonvulsant activity of NaV1.6 inhibition.
