Number of Participants With Electrocardiogram (ECG) Abnormalities Recorded as Treatment-Emergent Adverse Events (TEAEs)

Treatment-emergent adverse event (TEAEs) were defined as events that occur following the first injection of study treatment, or that started prior to the first injection and worsened during treatment. An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent adverse events were defined as adverse events/serious adverse events that started or worsened after the study drug treatment.

Time frame: From Screening (Day -28) to Post Therapy Day 30

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs)

Treatment-emergent adverse event (TEAEs) were defined as events that occur following the first injection of study treatment, or that started prior to the first injection and worsened during treatment. An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An Serious Adverse Event (SAE) was an AE 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. Treatment-emergent adverse events were defined as adverse events/serious adverse events that started or worsened after the study drug treatment.
