Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs)
Ramy czasowe: From Study Drug Administration (Day 1) Through the Follow-up Period (Day 361)
|
An adverse event (AE) is any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug.
A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening situation (immediate risk of dying); persistent or significant disability/incapacity of a participant who received MEDI8897.
TEAEs and TESAEs were the events that occurred between administration of study drug (Day 1) and Day 361 that were absent before treatment or that worsened relative to pre-treatment state.

From Study Drug Administration (Day 1) Through the Follow-up Period (Day 361)

|
Number of Participants With Treatment-Emergent Adverse Events of Special Interest
Ramy czasowe: From Study Drug Administration (Day 1) Through the Follow-up Period (Day 361)
|
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 (that is, within 24 hrs of knowledge of the event) to the sponsor.
The AESIs for this study were hepatic function abnormality meeting the definition of Hy's law, hypersensitivity reactions including anaphylaxis, immune complex disease, and thrombocytopenia.
Treatment-emergent AESIs were collected from the time of dosing until Day 361 post-dose.
|
From Study Drug Administration (Day 1) Through the Follow-up Period (Day 361)
|
|
Number of Participants With Clinical Laboratory Abnormalities Reported as Treatment-Emergent Adverse Events
Ramy czasowe: From Study Drug Administration (Day 1) Through the Follow-up Period (Day 151)
|
Laboratory abnormalities determined by the investigator to be clinically significant that occurred after study drug dosing through 151 days post-dose that were absent before treatment or that worsened relative to pre-treatment state were reported as TEAEs.
Laboratory evaluations (haematology and serum chemistry) of blood samples were performed.
