Detailed Description

This is a double-blind, randomized, placebo-controlled study to evaluate the efficacy and safety of IV ganaxolone in status epilepticus. Investigational product will be added to standard of care before IV anesthetic during the treatment of SE. Subjects will be screened for inclusion/exclusion criteria prior to receiving investigational product by continuous IV infusion. Subjects will be followed for approximately 4 weeks. Subjects who are known to be at risk for SE may be consented or assented prior to an SE event.
