Outcomes

Primary Outcomes

The rate of patients alive without progression 8 months after the inclusion.

The rate of patients alive without progression 8 months after the inclusion.

Secondary Outcomes

  • PFS will be defined as the time between date of inclusion and the date of the first radiological progression using RECIST v1.1 criteria and according to the investigator assessment or death
  • DCR will be defined at each time-point as complete (CR), partial (PR), stability (S), progression (P) or not evaluable with imageries and according to the investigator
  • ORR will be evaluated throughout the treatment by the imageries and according to RECIST v1.1 criteria.
  • BOR will be evaluated throughout the treatment by the imageries and according to RECIST v1.1 criteria
  • DoR is defined as the time between the first response of the patient and the date of radiological progression or death
  • TTP will be defined as the time between the date of inclusion and the date of the first radiological progression. The death linked to the cancer’s evolution will also be considered as an event
  • OS is defined by the time between the date of inclusion and the date of death (regardless of the cause)
  • Quality of life will be assessed with the EORTC QLQC30 questionnaire at each evaluation. The questionnaires are completed before the first treatment and during the study
  • Geriatric assessments will be performed at baseline and during treatment using the G-CODE and G8-SCORE
  • Toxicity, according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v5.0 will be recorded until 30 days after the last administration of treatment
