Traditional rodent seizure models (chemically induced convulsions, corneal kindling); not tested in a Cdkl5 disease model
“GNX (IP or oral) was active in several traditional rodent seizure models (eg, chemically-induced convulsions, corneal kindling). GNX was not tested for activity in a Cdkl5 disease model.”

Why that model
Cdkl5 knockout mouse models do not exhibit overt seizures
“While Cdkl5 knockout mouse models have been generated, these do not exhibit overt seizures.”

Reviewer's view of the efficacy data
EMA: proof of concept that ganaxolone protects against convulsions adequately demonstrated in several seizure models
“GNX demonstrated potent, broad, GABAA-mediated anticonvulsant activity in several types of seizure models tested. The proof of concept that GNX is protective of convulsion is adequately demonstrated.”
