Rodent anticonvulsant, EEG, anxiolytic-like and sedation models (target engagement)
“PD target engagement was also studied in rodent models of anticonvulsant, electroencephalographic, anxiolytic-like, and sedative activity consistent with the GABAA receptor PAM mechanism.”
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Reviewer's view of the efficacy data
EMA: predictable pharmacodynamic profile (anticonvulsant, anxiolytic-like, sedative) in rodent models
“Zuranolone, a GABAA receptor PAM under development for PPD and MDD, exhibits a predictable pharmacodynamic profile with anticonvulsant, anxiolytic-like, and sedative effects in rodent models.”
