Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR) Per Response Evaluation Criteria in Solid Tumors (RECIST) Version (v) 1.1 by Investigator AssessmentFrom start of treatment on Day 1 up to 3.8 months

ORR was defined as the percentage of participants who achieved a confirmed complete response (CR) or partial response (PR) as determined by investigator per RECIST version 1.1. As per RECIST version 1.1, CR was defined as disappearance of all extranodal lesions, the regression of all nodal lesions to less than (\<)10 millimeter (mm) short axis and the normalization of tumor marker level. PR was defined as greater than or equal to (\>=) 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference baseline sum of diameters of target lesions.

Secondary Outcome Measures
NameTimeMethod
Duration of Response (DOR) as Per RECIST Version 1.1From the date of first documented response up to date of first documented PD or death (up to 3.8 months)

DOR was defined as time from date of first documented response (CR/PR) until date of first documented progressive disease (PD) or death, whichever occurred first. As per RECIST version 1.1, CR was defined as disappearance of all extranodal lesions, the regression of all nodal lesions to \<10 mm short axis and the normalization of tumor marker level. PR was defined as \>=30% decrease in the sum of diameters of target lesions, taking as reference baseline sum of diameters of target lesions. PD was defined as an increase of at least 20% in the sum of the diameters of target lesions, taking as reference the smallest sum of the diameters of target lesions recorded since treatment started. There was no participant who had event (CR/PR), hence data could not be collected and analyzed for this outcome measure.

Disease Control Rate (DCR) as Per RECIST Version 1.1From start of treatment on Day 1 up to 3.8 months

DCR was defined as the percentage of participants achieving CR or PR or stable disease (SD) for at least 11 weeks as defined by RECIST version 1.1. As per RECIST version 1.1, CR was defined as disappearance of all extranodal lesions, the regression of all nodal lesions to \<10 mm short axis and the normalization of tumor marker level. PR was defined as \>=30% decrease in the sum of diameters of target lesions, taking as reference baseline sum of diameters of target lesions. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD was defined as an increase of at least 20% in the sum of the diameters of target lesions, taking as reference the smallest sum of the diameters of target lesions recorded since treatment started.

Progression Free Survival (PFS) as Per RECIST Version 1.1From start of the treatment (Day 1) until disease progression or death (up to 3.8 months)

PFS was defined as the time from the date of first dose of study drug until the date of objective disease progression or death by any cause, whichever comes first, based on investigator assessment using RECIST Version 1.1. PD was defined as an increase of at least 20% in the sum of the diameters of target lesions, taking as reference the smallest sum of the diameters of target lesions recorded since treatment started.

Overall Survival (OS)From start of the treatment (Day 1) until death due to any cause (up to 3.8 months)

OS was defined as the time from the date of first dose of study drug until the date of death due to any cause.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) Based on National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5.0From start of the treatment (Day 1) up to 30 days after last dose of study drug or start of subsequent anticancer therapy (up to 3.8 months)

An adverse event (AE) was any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. TEAEs was defined as AEs occurring at or after first dose of study drug up to 30 days after last dose or until the start of new anticancer therapy, whichever occurred first. TEAEs were graded according to NCI-CTCAE version 5.0. Grade 1- Mild; Grade 2- Moderate; Grade 3- Severe or medically significant but not immediately life-threatening; Grade 4- Life-threatening consequences; Grade 5- Death related to AE. All TEAEs including serious and non-serious events were reported in this outcome measure.

Number of Participants With Clinically Significant Abnormalities in Laboratory ParametersFrom start of the treatment (Day 1) up to 30 days after last dose of study drug or start of subsequent anticancer therapy (up to 3.8 months)

Number of participants with clinically significant abnormalities in laboratory parameters (serum chemistry and hematology) were reported. Clinically significant abnormalities were determined based on investigator's discretion.

Number of Participants With Clinically Significant Abnormalities in Vital Signs ValuesFrom start of the treatment (Day 1) up to 30 days after last dose of study drug or start of subsequent anticancer therapy (up to 3.8 months)

These measurements were taken after the participants had rested for at least 5 minutes in a quiet setting without distractions. Clinical significance of any vital signs was determined based on investigator's discretion.
