Title Safety Population: Time to First Grade 3 or 4 Hematological Toxicity and Liver Toxicity
Description Hematologic and hepatic toxicity was assessed using Common Terminology Criteria for Adverse Events version 3.0 (CTCAE). Hematologic and hepatic function included absolute lymphocyte count (ALC), hemoglobin level, white blood cell (WBC) count, absolute neutrophil count (ANC), platelets, alanine transaminase (ALT), aspartate transaminase (AST) and bilirubin. Time to first CTCAE Grade 3 or 4 hematological or liver toxicity was analyzed by treatment group using Kaplan-Meier plots of probability of surviving toxicity-free and point estimates of percentiles. According to CTCAE version 3.0: Grade 1=mild, Grade 2=moderate, Grade 3=severe, Grade 4=life threatening or disabling and Grade 5=Death. 10th, 20th, 25th, 50th and 75th percentiles were estimated from Kaplan-Meier survival curve.

Title Safety Population: Median Time to Recovery From Grade 3 or 4 Hematological and Hepatic Toxicity
Description Hematologic and hepatic toxicity was assessed using Common Terminology Criteria for Adverse Events (CTCAE). Hematologic and hepatic function included absolute lymphocyte count (ALC), hemoglobin level, white blood cell (WBC) count, absolute neutrophil count (ANC), platelets, alanine transaminase (ALT), aspartate transaminase (AST) and bilirubin. According to CTCAE version 3.0: Grade 1=mild, Grade 2=moderate, Grade 3=severe, Grade 4=life threatening or disabling and Grade 5=Death. Time to recovery from grade 3 or 4 hematological or liver toxicity were reported: lymphocytes, platelets, neutrophils, white blood cells, hemoglobin, Alanine transaminase (ALT), Aspartate transaminase (AST), Platelets and Bilirubin. Recovery from a Grade 3 or 4 toxicity is defined as a return to a Grade 0 or 1.
