Continous first line therapy

Primary Outcome Measures :
  1. Overall survival (OS) [ Time Frame: 24 months ]
    The primary efficacy endpoint is the OS which is defined as the time interval starting with the randomization and lasting until death (=event) or until the date of last information available from the patient.

Secondary Outcome Measures :
  1. OS1 [ Time Frame: 24 months ]

    The secondary efficacy endpoint OS1 is defined as the time interval starting at the first cycle of induction therapy and lasting until death (=event) or until the date of last information available from the patient.

    OS1 will be estimated by Kaplan-Meier estimates. The comparison between the treatment groups will be performed using the log-rank test with a significance level of α = 2.5% for the 1-sided test. The OS1 will be presented as Kaplan-Meier figures also.

Other Outcome Measures:
  1. Progression-free survival (PFS) PFS from the start of the first cycle of induction therapy (PFS1) ass [ Time Frame: 24 months ]
    Progression-free survival is the time after randomization to either disease progression (PD), measured using RECIST 1.1 and irRC criteria and confirmed via centralized review or death
