  • Determine the duration of response (DOR) in the 2 treatment arms
  • Determine the duration of MRD negativity (by NGS and NGF)
  • Determine the rate of sustained for 1-year MRD negativity (by NGF) (from post ASCT consolidation to post light consolidation)
  • Determine the time to progression (TTP) in the 2 treatment arms
  • Determine the overall survival (OS) in the 2 treatment arms
  • Determine the time to next therapy (TNT) in the 2 treatment arms
  • Determine the progression-free survival 2 (PFS2) in the 2 treatment arms
  • Determine whether tumor response and outcome may change in subgroups with different prognosis according to current prognostic factors
  • Determine safety in the 2 treatment arms

Registration Details

Required regulatory and administrative documents must be provided to the EMN Data Center before registration of the first patient. This will always include an Ethics Committee approval for the investigational site. The EMN Data Center will provide each investigator with an overview of the required documents. Each investigational site will be notified when all requirements are met and enrolment can start
