If the subject's exact age was not known, the subject was excluded. -Subjects who experienced 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: Presented, at the time, with seizure (convulsive) activity and 3 or more convulsions within the preceding hour;in succession without recovery of consciousness or presented, at the time, with a single seizure (convulsive) persisting ≥5 minutes. |
|
E.4 | Principal exclusion criteria |
- Female subjects who were pregnant, suspected to be pregnant, or nursing. - Subjects with major trauma, not necessarily restricted to the head, as the cause of the seizure. - Subjects with major trauma, not necessarily restricted to the head, as the cause of the seizure. - Subjects with known or suspected recurrent seizures due to illegal drug or alcohol withdrawal. - Subjects with seizures due to illegal drug or acute alcoholic intoxication - Subjects with seizures of psychogenic origin - Subjects with seizures due to severe cases of encephalitis or meningitis, as determined by the investigator. - Subjects with a known history of hypersensitivities, nonresponsiveness or contraindications to benzodiazepines (ie, clinically significant respiratory depression, severe acute hepatic failure, myasthenia gravis, syndrome of sleep apnea, glaucoma with closed angle, or use of concomitant drugs determined by the investigator to have a contraindication to the use of benzodiazepines.) - Subjects with a known history of benzodiazepine abuse. - Subjects who had not responded to previous administrations of midazolam systemic therapies, including Midafresa and/or Dormicum. - Subjects who needed emergent surgical intervention and general anesthesia/intubation. - Subjects who had been receiving human immunodeficiency virus (HIV) protease inhibitors or HIV reverse transcriptase inhibitors.
Subjects with severe cerebral anoxia (except cerebral palsy), in the judgment of the healthcare provider. Had used an IP or been enrolled in a clinical study (including vaccine studies) that, in the investigator’s opinion, may impact this TDC Americas-sponsored study. Subject had prior placement of a vagus nerve stimulator. |

|
The study was ended after 3 subjects completed the study assessments as per the agreement with the Japanese regulatory authority, Pharmaceuticals and Medical Devices Agency (PMDA), that the study would be closed upon NDA approval. Therefore, the final SHP6150-302 study report is based on data available up to 13 October 2020 (last subject completed date), to be concurrent with the Study SHP615-301 report: 3 patients were analyzed for safety; 3 patients were analyzed for efficacy. |
