DLT was defined as any of the following adverse events occurring in the first two cycle of treatment (28 days), unless there was a clear alternative explanation: hematologic: grade 4 neutropenia lasting \>7 days, febrile neutropenia; grade ≥3 neutropenic infection; grade ≥3 thrombocytopenia with clinically significant bleeding or requiring medical intervention; grade 4 thrombocytopenia; grade 4 anemia; grade ≥3 anemia related to hemolysis or autoimmune disease. non hematologic: grade ≥3 toxicities that were considered clinically significant, including cytokine release syndrome, infusion reactions and allergic reactions, except those that had not been maximally treated or could be easily treated. The severity of adverse events was graded as per common terminology criteria for adverse events(CTCAE) version 4.03, and there were no DLTs reported.

Adverse event (AE) was graded by the investigator according to CTCAE version 4.03 and coded using the Medical Dictionary for Regulatory Activities (MedDRA): Grade 3 (Severe) events=unacceptable or intolerable events. Grade 4 (Life-threatening) events caused participant to be in imminent danger of death. Grade 5 (Death) events=death related to an AE. Treatment-emergent events=between first dose of study drug and up to 35 days after last dose that were absent before treatment or that worsened relative to pretreatment state. TEAEs were defined as those with initial onset or increasing in severity after the first dose of study medication. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

Following parameters were analyzed for laboratory examination: hematology (hemoglobin, hematocrit, platelet count, white blood cell count, total neutrophils, eosinophils, monocytes, basophils, lymphocytes, partial thromboplastin time (PTT), Prothrombin (PT), PT international ratio); liver function (aspartate aminotransferase(AST), alanine aminotransferase(ALT), total bilirubin, gamma-glutamyl transpeptidase(GT), alkaline phosphatase, albumin, total protein); renal function (blood urea nitrogen, creatinine, uric acid); electrolytes (sodium, potassium, chloride, calcium , phosphate, magnesium); clinical chemistry (glucose, creatine kinase, thyroxine (T4), thyroid stimulating hormone(TSH)), Amylase, Lipase), urinalysis (dipstick \[protein, blood\], microscopy \[urine red blood cell (RBC), white blood cell (WBC), Epithelial Cells\], miscellaneous \[urine casts and bacteria\]).
