Measure Description |
Time Frame |
---|---|---|
Part A, B, C, D and E: Incidence and severity of Adverse Events
Time Frame: Up to 28 days after last administration
|
A treatment-emergent adverse events (TEAE) will be summarized by treatment and overall, and summarized for each treatment by severity and relationship to study drug.
All TEAEs leading to withdrawal, or SAEs, will be summarized.
|
Up to 28 days after last administration
|
Part A, B, C, D and E: Number of subjects with clinical laboratory test abnormalities
Time Frame: Up to 28 days after last administration
|
The clinical laboratory will include hematology (hematocrit, hemoglobin, mean cell hemoglobin, mean cell hemoglobin concentration, mean cell volume, platelet count, red blood cell count, white blood cell count), clinical chemistry (alanine aminotransferase, albumin, alkaline phosphatase, aspartate aminotransferase, blood urea nitrogen, calcium, chloride, cholesterol, creatinine, creatine phosphokinase, direct bilirubin, estimated glomerular filtration rate, gamma glutamyl transferase, glucose.
inorganic phosphate, iron, lactate dehydrogenase, phosphorus, potassium, sodium, total bilirubin, total CO2, total protein, triglyceride, urea, uric acid), and urinalysis (bilirubin, blood, color and appearance, glucose, ketones, leukocyte esterase, nitrite, pH, protein, specific gravity, urobilinogen, microscopic examination, electrolytes).
