An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE is defined as an adverse event with an onset that occurs after receiving study drug.
The percentage of participants with any markedly abnormal standard safety laboratory values, including haematology, serum chemistries, or urinalysis, during the treatment period.
The percentage of participants who meet markedly abnormal criteria for vital signs after dosing, including oral body temperature (temp.), respiration rate, pulse rate (PR) Systolic blood pressure (SBP) and Diastolic blood pressure (DBP) for assessment in positions of supine or standing. Vital signs were considered abnormal if they were beyond the values defined in categories.
The percentage of participants who meet markedly abnormal criteria for ECG parameters as specified by the protocol and statistical analysis plan during the treatment period. ECG parameters were considered abnormal if they were beyond the values defined in categories.
