Primary Outcome Measures
NameTimeMethod
Part A, B, C, D and E: Number of subjects with clinically significant change in body weightUp to 28 days after last administration

Change in body weight (kg) at baseline and post dose will be measured. Clinical significance will be determined by the investigator.

Part A, B, C, D and E: Number of subjects with vital signs abnormalitiesUp to 28 days after last administration

The vital sign will include blood pressure (mmHg), pulse rate (bpm), respiratory rate (breaths/min), and body temperature (degree Celsius). Abnormality will be determined by the investigator.

Part A, B, C, D and E: Incidence and severity of Adverse EventsUp 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.

Part A, B, C, D and E: Number of subjects with clinical laboratory test abnormalitiesUp 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). Abnormality will be determined by the investigator.

Part A, B, C, D and E: Number of subjects with abnormal findings in physical examinationsUp to 28 days after last administration

The physical examination will typically include general appearance, head and neck, eyes, ear, nose and throat, lymph nodes, thyroid, cardiovascular, respiratory, abdomen, nervous, skin, musculoskeletal, peripheral vascular and extremities and be performed at Investigator's discretion based on reported symptoms. Abnormality will be determined by the investigator.
