Objective Response Rate is defined as the proportion of participants with a best response of complete response (CR) or partial response (PR) according to the International Working Group criteria. CR is defined as disappearance of all evidence of disease. PR is defined as 50 percent (%) decrease in the sum of the product of the perpendicular diameters (SPD) of up to 6 largest dominant nodal masses and greater than or equal to (\>=) 50% decrease in SPD of spleen/liver nodules.
The Maximum Tolerated Dose, defined as the highest dose where less than or equal to (\<= 1) out of 6 subjects experiences a dose limiting toxicity (DLT) during the DLT evaluation period (Day 1 to Day 28 of Cycle 1) or the highest protocol specified dose not exceeding MTD.
An Adverse Event (AE) is any unfavourable and unintended signs, symptoms, or diseases temporally associated with use of study drug, whether or not considered related to study drug. SAE is any AE that resulted in death, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, life-threatening, a congenital anomaly/birth defect, or an important medical event. TEAEs are defined as AEs present at baseline that worsened in intensity after administration of study drug, or events absent at baseline that emerged after administration of study drug, up to 90 days after the end of treatment (EOT).
An abnormal laboratory findings that was judged by the investigator to be medically significant was reported as an AE. TEAEs were defined as events present at baseline that worsened in intensity after administration of study drug, or events absent at baseline that emerged after administration of study drug, for the period extending to 90 days after the end of study drug.
Vital signs included parameters such as blood pressure, temperature, respiratory rate, and pulse oximetry. An abnormal vital signs and physical findings that was judged by the investigator to be medically significant was reported an AE. TEAEs were defined as events present at baseline that worsened in intensity after administration of study drug, or events absent at baseline that emerged after administration of study drug, for the period extending to 90 days after the end of study treatment.
The best overall response was calculated, based upon the disease assessments recorded during the study visits, and summarized with the number of participants for the following categories: complete response (disappearance of all evidence of disease), partial response (regression of measurable disease and no new sites), stable disease (SD), progessive disease (PD), and non- evaluable (NE).
