The primary phase was well controlled, with randomized quadruple blinding, placebo comparison, and 350 analyzed participants, and it used the clinical endpoint of change in seizure frequency. However, the primary endpoint was missed: the difference between ganaxolone and placebo was not statistically significant (p=0.1788), so the study provides well-designed but inconclusive evidence.
