Brief Summary:

Study design: Randomised, controlled, multi-centre, open-label, phase III trial (with a single intervention registration phase).

Primary Objectives

The primary objectives of this study are to determine:

  • The impact on Depth of Response (DoR: less than VGPR versus VGPR or better) when salvage ASCT conditioning is augmented by the addition of a proteasome inhibitor
  • The influence of a consolidation and maintenance strategy on the Durability of Response (DuR:PFS)

Secondary objectives

The secondary objectives of this study are to determine:

  • Overall survival
  • Time to disease progression
  • The overall response rate following ixazomib, thalidomide and dexamethasone (ITD) re-induction
  • Time to next treatment
  • Progression-free survival 2 (PFS2)
  • Duration of response
  • Minimal Residual Disease (MRD) negative rate post re-induction, post-ASCT and conversion after ITD consolidation
  • Engraftment kinetics
  • Toxicity and safety
  • Quality of life (QoL)

Participant population (refer to protocol section 9 for a full list of eligibility criteria).

  • Relapsed MM (with measurable disease by IMWG criteria) previously treated with ASCT
  • First progressive disease (PD) at least 12 months since first ASCT, requiring therapy.
  • ECOG Performance Status 0-2
  • Aged at least 18 years
  • Adequate full blood count and renal, hepatobiliary, pulmonary and cardiac function
  • Written informed consent

Interventions: All participants will be registered at trial entry and will receive re-induction therapy with 4-6, 28-day cycles of ixazomib, thalidomide and dexamethasone (ITD), in order to reach maximum response. Participants who achieve at least stable disease (SD) will be randomised on a 1:1 basis to receive either conventional ASCT (ASCTCon), using melphalan, or augmented ASCT (ASCTAug), using melphalan with ixazomib. All participants achieving or maintaining a minimal response (MR) or better following trial ASCT will undergo a second randomisation to consolidation and maintenance or no further treatment. Participants randomised to consolidation and maintenance will receive treatment as follows: consolidation with 2 cycles of ITD and maintenance with ixazomib until disease progression.

Number of participants: 406 participants will be registered into the trial to allow 284 participants to be randomised at the first randomisation (R1) and 248 participants to be randomised at the second randomisation (R2).

Primary Outcome Measures :
  1. Overall response rate [ Time Frame: 100 days post-ASCT ]
    Overall response rate following ASCT will be determined according to the IMWG Uniform Response Criteria for Multiple Myeloma. This endpoint will be defined as a binary dichotomization of response (≥VGPR vs <VGPR) at an assessment 100 days after the date of stem cell transplant.

  2. Progression-free survival [ Time Frame: From date of registration to date of disease progression, up to 120 months. ]

Secondary Outcome Measures :
  1. Overall survival [ Time Frame: From date of R2 to date of death, up to 120 months ]
    Overall survival is defined as the time from randomisation to the consolidation/maintenance part of the trial post-ASCT to death from any cause or last follow-up.

  2. Time to disease progression [ Time Frame: From date of registration until date of disease progression, up to 120 months ]
    Time to disease progression is defined as time from randomisation to the consolidation/maintenance part of the trial post-ASCT to first documented evidence of disease progression. Participants who die without disease progression will be censored in the analysis.

  3. Overall response rate to ITD re-induction [ Time Frame: At the end of re-induction - after 4-6 re-induction cycles (each cycle is 28 days) ]
    Overall response rate following re-induction will be determined according to the IMWG Uniform Response Criteria for Multiple Myeloma.

  4. Upgrade in response after two cycles of ITD consolidation [ Time Frame: After 2 cycles of ITD consolidation (each cycle is 28 days) ]
    Upgrade in response after 2 cycles of ITD consolidation - response rate following ITD consolidation will be determined according to the IMWG Uniform Response Criteria for Multiple Myeloma. This endpoint will be defined as a binary dichotomization of response (≥VGPR vs <VGPR).

  5. Progression-free survival 2 (PFS2) [ Time Frame: Date of R2 to date of second disease progression, up to 120 months ]
    Progression-free survival 2 is defined as the time from second randomisation to the consolidation/maintenance part of the trial post-ASCT to second documented disease progression (or the start of next line anti-myeloma treatment), or death from any cause, whichever occurs first. Participants alive and for whom a second progression after second randomisation has not been observed will be censored at the last day they were known to be alive and second progression-free.

  6. Time to next treatment [ Time Frame: Date of registration to start date of new therapy, up to 120 months ]
    Time to next line treatment is defined as the time from the date of randomisation to the date of commencement of next line treatment. Participants who do not receive next line treatment will be censored at the date of the last assessment or follow-up visit where they are known to have received no new therapy.

  7. Duration of response [ Time Frame: Date of achieving at least partial response to date of disease progression, up to 120 months ]
    Duration of response to protocol treatment is defined from the time of achieving at least a partial response to the date of first documented evidence of disease progression. Participants who die prior to documentation of disease progression will be censored at the date of death. Participants dying from causes not primarily due to progression will also be censored at the date of death. Participants not reaching disease progression at the time of analysis will be censored at the last date known to be progression-free.
