What was measured

Duration of response was defined as the time interval from the time that the measurement criteria are first met for CR/PR (whichever is first recorded) until the first date that the progressive disease is objectively documented or death. Patients without progressive disease or death were censored at the last valid response assessment. CR for target lesion: disappearance of all extranodal lesions and all pathological lymph nodes must have decreased to \<10 mm in short axis. CR for non-target lesion: Disappearance of all extranodal non-target lesions, all lymph nodes must be non-pathological in size (\<10mm short axis) and norrmalization of tumor marker level. PR: at least a 30% decrease in the SLD of target lesions, taking as reference the baseline sum diameters. The analysis was based on the Kaplan-Meier (KM) Estimates.

Analysis population: ITT Population included all participants who were randomized to each regimen regardless of whether they received study drug or adhered to the assigned dose. Participants who had confirmed CR or PR were evaluable for this outcome measure.

Groups in this outcome
