Descrição da medida |
Prazo |
|---|---|---|
|
Number of Participants With Death, Serious Adverse Events, Treatment-related Adverse Events (AE), AEs Leading to Discontinuation, and AEs of Hypersensitivity
Prazo: Days 1 through 29, continuously
|
An AE is any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that does not necessarily have a causal relationship with treatment.
An SAE is any unfavorable medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency or abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization.
Treatment-related=possibly, probably, or certainly related to and of unknown relationship to study treatment
|
Days 1 through 29, continuously
|
|
Number of Participants With AEs by Maximum Severity
Prazo: Days 1 through 29, continuously
|
An AE is any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that does not necessarily have a causal relationship with treatment.
Mild=asymptomatic or minor symptoms; intervention not indicated.
Moderate=requiring only minimal, local, or noninvasive intervention.
Severe=significant symptoms but not life-threatening; hospitalization or invasive intervention indicated.
Life-threatening=indicating intensive care or urgent invasive intervention.
|
Days 1 through 29, continuously
|
|
Number of Participants With Clinical Laboratory Findings of Grade O or Higher in Platelet, White Blood Cell (WBC), Lymphocyte, and Neutrophil Counts
Prazo: Baseline and Day 29 from Baseline
|
Abnormal laboratory findings were recorded as AEs when considered clinically significant (unusual for the surgical population or individual participant) by the investigator, when associated with symptoms, when requiring specific treatment, or when requiring a change in participant management.LLN=lower level of normal.
Platelets: Grade 0=normal.
WBC: Grade 0=normal.
Lymphocytes: Grade 0=normal; Grade 1=<LLN x 0.8-10^9/L.
Neutrophils: Grade 0=normal; Grade 1=<LLN-1.5x10^9/L;
Grade 2=<1.5-1.0x10^9/L
|
Baseline and Day 29 from Baseline
|
|
Number of Participants With Clinical Laboratory Findings of Grade 0 or Higher in Hemoglobin Levels
Prazo: Baseline and Day 29 from Baseline
|
LLN=lower level of normal.
Grade 1=100 g/L to <LLN; Grade 2=80 to <100 g/L; Grade 3=65 to <80 g/L; Grade 4=<65 g/L.
|
Baseline and Day 29 from Baseline
|
|
Number of Participants With Clinical Laboratory Findings of Grade 0 or Higher in Creatinine Levels
Prazo: Baseline and Day 29 from Baseline
|
ULN=upper level of normal.
Grade 0=normal; Grade 1=>ULN to 1.5 x ULN.
|
Baseline and Day 29 from Baseline
|
|
Number of Participants With Elevations in the Coagulation Parameter of Activated Partial Thromboplastin Time (aPPT)of Grade 0 or Higher
Prazo: Baseline and Day 29 from Baseline
|
ULN=upper limit of normal.
Grade 0=normal; Grade 1=ULN to 1.5 x ULN.
|
Baseline and Day 29 from Baseline
|
|
