• Parent, guardian, or legally authorized representative of the child who provides informed consent and assent (when applicable) to participate in the study after initial stabilization of the subject with SE in hospital or emergency room during the SHP615-301 study. The subject also provides informed consent prior to participation, where applicable.

• Parent, guardian, or legally authorized representative who have received appropriate training/education and are deemed qualified by the investigator and are willing to:

1. Properly administer MHOS/SHP615.

2. Record seizure information and dosing of MHOS/SHP615 in a subject diary (including time of seizure onset, type of seizure, time necessary to administer MHOS/SHP615, time between MHOS/SHP615 administration to seizure cessation, etc.)

3. Follow the necessary instructions to secure the safety of the subject.

• Subjects who experience generalized tonic-clonic SE with seizures accompanied by loss of consciousness with any of the following characteristics persistent at the time of study drug administration:

1. Currently presenting with seizure (convulsive) activity and 3 or more convulsions within the preceding hour

2. Currently presenting with seizure (convulsive) and 2 or more convulsions in succession without recovery of consciousness.

3. Currently presenting with a single seizure (convulsive) persisting greater than or equal to (>=) 5 minutes.
