Endpoints

Primary endpoints

  • {"endpoint_text":"- Improvement in the percentage of patients MRD-negative in Arm A vs. Arm B when considering B1 endpoint.

  • {"endpoint_text":"- Non-inferiority in the percentage of patients MRD-negative in Arm A vs. Arm B when considering B2 endpoint. B2 endpoint: VRD extended plus ERI impact: any patient who achieves MRD negativity with ERI before finishing the 18 cycles + ASCT will be considered MRD-negative at that time.","definition_or_measurement_approach":"MRD negativity assessed by NGF after 18 cycles + ASCT; B2 considers VRD extended plus ERI impact and counts patients who achieve MRD-negativity with ERI before finishing 18 cycles + ASCT as MRD-negative."}

Other endpoints

  • {"endpoint_text":"- Other secondary objectives 2.4 Progression-Free Survival (PFS) 2.5 Overall Response Rate (ORR): PR or better (PR, VGPR, CR, sCR). 2.6 Complete Response Rate (CRR): CR or better (CR, sCR). 2.7 Time to Response (TTR), among participants who achieve confirmed PR or better. 2.8 Duration of Response (DoR) among participants who achieved PR or better. 2.9 PFS2 2.10 Overall Survival (OS)","definition_or_measurement_approach":"PFS, ORR (PR or better including VGPR, CR, sCR), CRR (CR or better), TTR among those with confirmed PR or better, DoR among responders, PFS2, and OS as defined in protocol (standard oncology efficacy endpoints)."}

Consent Approach
Informed consent: participants must provide voluntary written informed consent prior to any study-specific procedures ("Patient has given voluntary written informed consent before performance of any study-related procedure ..."). Consent may be withdrawn at any time without prejudice to future medical care. Subjects with conditions that impair understanding of the informed consent are excluded. Consent documentation exists (L1_ICF documents), including a Spanish principal ICF (file L1_SIS-ICF_Principal v5-0_ES_14Mar2025). No assent procedures for minors are described (trial restricts age ≤65).
