Study Overview
=================
Brief Summary
-----------------
This study is a survey in Japan of midazolam oromucosal solution used to treat people with status epilepticus. The study sponsor will not be involved in how the participants are treated but will provide instructions on how the clinics will record what happens during the study. The main aim of the study is to check for side effects related from midazolam oromucosal solution and to check if midazolam oromucosal solution improves symptoms of status epilepticus. During the study, participants with status epilepticus will take midazolam oromucosal solution according to their clinic's standard practice.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Who Experienced At Least One Treatment-Emergent Adverse Event (TEAE) | An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation subject administered a pharmaceutical product. It does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a pharmaceutical product (including an investigational product for a new indication in Japan), whether or not related to the pharmaceutical product. | Up to 24 hours after drug administration | 
| Number of Participants With Serious Adverse Events | A serious AE is any untoward medical occurrence or effect that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability / incapacity, is a congenital anomaly / birth defect or is medically important due to other reasons than the above mentioned criteria. | Up to 24 hours after drug administration | 
| Number of Participants With Therapeutic Success | Therapeutic success is defined as cessation of seizure activity within 10 minutes and sustained absence of seizure activity for 30 minutes following the first dose of midazolam oromucosal solution. Number of participants with therapeutic success will be reported. | Up to 30 minutes after drug administration |
