MeasureTime frameDescription
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)Day 1 to Day 29An adverse event (AE) is any unfavourable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. A TEAE is defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug.
Number of Participants With Treatment-Emergent Serious Adverse Events (TESAEs) and Treatment Emergent Adverse Events of Special Interest (TEAESIs)Day 1 to Day 61An AE is any untoward medical occurrence attributed to study drug in a participant who received investigational product. TESAE was an event resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly that occurred after the initial receipt of the study drug. An AESI was one of scientific and medical interest specific to understanding of study product and may have required close monitoring and rapid communication by investigator to the sponsor. TEAESIs were collected from the time of dosing through Day 61 after the last dose of study drug and included anaphylaxis, other serious allergic reactions, infusion-related reactions, hepatic function abnormalities and immune complex disease.
Number of Participants With Abnormal Clinical Laboratory Parameters Reported as Treatment-Emergent Adverse Events (TEAEs)Day 1 to Day 29Any medically significant change in laboratory evaluations were recorded as adverse events. Following parameters were analyzed for laboratory examination: Hematology, serum chemistry, liver function, serum electrolytes and urinalysis.
Number of Participants With Abnormal Vital Signs Reported as Treatment-Emergent Adverse Events (TEAEs)Day 1 to Day 7Vital signs measurements included temperature, blood pressure (systolic and diastolic), pulse rate and respiratory rate.
