Time Frame: From the date of first dose of study drug to the date of first documentation of disease progression or death, whichever occurred first (up to 39 months)

Objective response was assessed by investigator based on the Lugano Classification (CT-Based) response criteria.
Objective response rate was defined as the percentage of participants who had a Best Overall Response (BOR) of complete response (CR) or partial response (PR).
CR was defined as the disappearance of all target and non-target lesions (non-lymph nodes).
All pathological lymph nodes (whether target or non-target) must have a reduction in their short axis to less than (<) 10 millimeters (mm).
PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
