Study Endpoints
Primary Endpoints
Efficacy: Number of Participants With Therapeutic Success
From start of study drug administration up to 30 minutes post-dose

Therapeutic success was defined as cessation of visible seizure activity within 10 minutes and sustained absence of visible seizure activity for 30 minutes following a single dose of SHP615 without the need for additional rescue medication. Number of participants with therapeutic success were reported.

Safety: Number of Participants With Respiratory Depression
Up to 24 hours post-dose

Respiratory depression, included the following measures within 24 hours after administration of the IP: i) Persistent decrease in oxygen saturation to \<92 percent (%) measured up to 24 hours post-dose (i.e., \<92% on room air for 2 minutes or more after dosing while monitoring \[per healthcare setting protocol and/or the clinical judgment of the physician\]. ii) Increase in respiratory effort such that assisted ventilation is used (bag-valve-mask ventilation or endotracheal intubation). Number of participants with respiratory depression were reported.

Percentage of Participants With Response Rate
From start of study drug administration up to 30 minutes post-dose

Response rate was defined as the percentage of participants with therapeutic success. Therapeutic success was defined as the cessation of visible seizure activity within 10 minutes with a sustained absence of visible seizure activity for 30 minutes following a single dose of MHOS/SHP615 without the need for additional rescue medication.

Secondary Endpoints
Efficacy: Number of Participants Who Had Sustained Absence of Seizure Activity for at Least 1, 4, and 6 Hours
