Ganaxolone, administered orally via a dosing syringe, is a steroid that targets specific brain receptors to prevent epileptic seizures.
The approval of ganaxolone is based on results from a Phase III clinical trial.
The double-blind placebo-controlled study involved 101 subjects aged two to 19 years.
The subjects were randomised with 50 receiving ganaxolone and 51 a placebo over 17 weeks.

Individuals experiencing adverse effects are encouraged to consult their healthcare provider and report the incident through the MHRA Yellow Card scheme, accessible online or via mobile app stores.
MHRA Healthcare Quality and Access interim executive director Julian Beach stated: “Keeping patients safe and enabling their access to high quality, safe and effective medical products are key priorities for us.
“We’re assured that the appropriate regulatory standards for the approval of this medicine have been met.
“As with all medicines, we will keep its safety under close review.”
