Part 2: Percentage of Participants With Adverse Events After Midazolam Administration Alone and in Combination With Risdiplam
Time Frame: Day 1 to Day 20 and up to 10+/-2 Days Post Final Dose or Early Termination
|
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which 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, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product.
Preexisting conditions which worsen during a study are also considered as adverse events.
