Inadequate bone marrow reserve or organ function as demonstrated by any of the following laboratory values: ANC < 1.5 x 10^9/L; Platelet count < 100 x 10^9/L; Hemoglobin < 8 g/L; ALT > 3x ULN; AST > 3x ULN; total bilirubin > 1.5x ULN (Gilbert's syndrome exception: total bilirubin ≤2.0x ULN and direct bilirubin within normal limits permitted); Creatinine >1.5x ULN concurrent with creatinine clearance < 50 ml/min; Proteinuria 3+ on dipstick or >500mg/24 hours; Sodium or potassium outside normal reference range for site; Cardiac criteria as listed
