Primary Outcome Measures:
  • Number of Dose Limiting Toxicity of Physical Examination [ Time Frame: baseline to 72 hours ]
    Physical examination, including skin, head, neck, eyes, ears, nose, throat, heart, lungs, abdomen (liver and spleen), neurological examination, lymph node and extremities, is measured at each visit from screening to follow-up.

  • Number of Dose Limiting Toxicity of Electrocardiograph [ Time Frame: baseline to 72 hours ]
    Electrocardiograph (ECG) is measured at each visit. At visit 2, subjects were measured at 1,2, 4, 8, 12 and 24 hours after drug administration.

  • Number of Dose Limiting Toxicity of Vital Sign [ Time Frame: baseline to 72 hours ]
    Vital sign, including heart rate, blood pressure and body temperature, are measured at each visit and at 1,2,3,4,8,12 and 24 hours after drug administration.

  • Number of Dose Limiting Toxicity of Laboratory Values [ Time Frame: baseline to 72 hours ]
    Laboratory tests are composed of hematology and blood chemistry and measured at each visit. Hematology are composed of RBC, WBC, platelets, hematocrit, hemoglobin, prothrombin time (PT) and partial thromboplastin time (aPTT). Blood chemistry are composed of AST, ALT, LDH, total bilirubin, BUN, serum creatinine, free thyroxine (FT4), TSH, sodium, calcium, potassium, glucose, LDL, HDL, cholesterol and HbA1c.

  • Number of Dose Limiting Toxicity of Columbia-Suicide Severity Rating Scale (C-SSRS) [ Time Frame: baseline to 72 hours ]
    C-SSRS is composed of suicidal ideation, intensity of ideation and suicidal behavior and measured at each visit.
