Description of intervention(s) / exposure
This is a randomised, multi-centre, open label phase 3 trial, with the primary objective to determine whether the addition of ixazomib to thalidomide and low dose dexamethasone maintenance therapy post-ASCT for MM patients improves progression free survival (PFS) and/or overall survival (OS).

Patients with symptomatic MM who are transplant eligibile will be registered prior to undergoing ASCT. Patients who have achieved clinical and haematologic recovery following ASCT will initiate screening for study eligibility no earlier than 75 days following ASCT, complete screening within 15 days, and be randomised no later than 115 days after ASCT.

Patients are randomised 1:1 to receive either:
Arm 1 (Control)- 12 cycles of thalidomide (100mg/day- oral tablet), dexamethasone (40mg/week- oral tablet); or
Arm 2 (Experimental): 12 cycles of thalidomide (100mg/day- oral tablet), dexamethasone (40mg/week-oral tablet), plus ixazomib therapy (4mg, on day 1, day 8, and day15 of each cycle- oral capsule);
for a maximum of 12 months.

A treatment cycle is defined as 28 days. Cycle 13 is the time-point at the end of consolidation treatment (cycles 1-12)

The study drugs will be administered or dispensed only to eligible patients under the supervision of the investigator or identified sub-investigator(s). The appropriate study personnel will maintain records of study drug receipt and dispensing.

Outcomes
Primary outcome [1] 298350 0
To determine whether the addition of ixazomib to thalidomide and low dose dexamethasone consolidation therapy post-ASCT for MM patients, improves progression free survival (PFS).
Timepoint [1] 298350 0
Progression free survival (PFS) is measured from the date of randomisation until the earliest date of relapse, progression, or death from any cause. Patients who have not relapsed, progressed or died by the study close-out date will have their PFS censored at the study close-out date for PFS, unless they are deemed lost to follow up before that date, in which case their PFS will be censored at the date that they were last known to be alive and progression-free. The study close-out date for PFS is the earliest of the last dates of disease assessment for patients who are alive, progression-free and on-study. Missing disease assessments will be handled as follows: if disease progression or death is documented after one single missing assessment, the actual event date of the progression or death will be used for the PFS date. If disease progression is documented after two or more missing assessments, the PFS time of these patients will be censored at the date of the last assessment as per the International Myeloma Working Group (IMWG) response criteria for MM.

Disease outcome measures are based on high vs standard risk disease (as defined by Revised International Staging System R-ISS for Multiple Myeloma) and as per the IMWG response criteria for MM.
Secondary outcome [1] 323911 0
To determine whether the addition of ixazomib to thalidomide and low dose dexamethasone improves overall survival (OS).
Timepoint [1] 323911 0
Patients will be assessed for OS (vital status) monthly during consolidation treatment, then cycle 13 onwards. OS is measured from the date of randomisation until the date of death from any cause. Patients who are not known to have died by the study close-out date will have their OS censored at the study close-out date for OS unless they are deemed lost to follow-up before that date, in which case their OS will be censored at the date they were last known to be alive. The study close-out date for OS is the earliest of the last dates of assessment of vital status for patients remaining on the study.
Secondary outcome [2] 323913 0
To determine salvageability at time of relapse, "PFS2", which is the time from randomisation to progression on first salvage (second line) treatment.
Timepoint [2] 323913 0
Following progression, patients will be followed up every 3 months to document disease outcome measures, as defined by the Revised International Staging System R-ISS for Multiple Myeloma and the IMWG response criteria for MM.
Secondary outcome [3] 323914 0
To determine the safety ixazomib in combination with thalidomide and low dose dexamethasone consolidation therapy post-ASCT in Multiple Myeloma patients.
Timepoint [3] 323914 0
Ongoing analysis from registration to end of follow up period (60 months). Study parameters include documentation of medication administered, adverse events (as per the Common Terminology Criteria for Adverse Events, CTCAE v4.0), and dose adjustments.
Secondary outcome [4] 323915 0
To assess the impact of the addition of ixazomib on Quality of Life (QoL)/Patient reported health outcomes (PRO).
Timepoint [4] 323915 0
Ongoing analysis from registration to the end of the follow up period (60 months). The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life - Core questionairre (QLQ-C30) version 3, and MM module (QLQ-MY20) will be used to assess PROs in the MM19 trial.
Questionnaires are to be completed at the following time points- Registration, 75-115 days post ASCT, day 1 of every 28 day cycle (cycle 1-cycle 12), day 1 of every month in the follow up period post- cycle 12, at disease progression, and every 3 months following progression in the overall survival follow up period.
Secondary outcome [5] 323918 0
To assess the cost-effectiveness of ixazomib in combination with thalidomide low and dose dexamethasone compared with thalidomide and low dose dexamethasone as consolidation therapy post-ASCT in Multiple Myeloma patients
Timepoint [5] 323918 0
Ongoing analysis from registration to end of follow up (60 months). Health economics data will include the following documentation: EUROQoL EQ-5D-5L questionnaire; hospitalisations; concomitant medications; AE/SAE treatment; protocol drug use.

Questionnaires are to be completed at the following time points- Registration, 75-115 days post ASCT, day 1 of every 28 day cycle (cycle 1-cycle 12), day 1 of every month in the follow up period post- cycle 12, at disease progression, and every 3 months following progression in the overall survival follow up period.
Secondary outcome [6] 324608 0
To determine whether the addition of ixazomib to thalidomide and low dose dexamethasone improves overall response rate (ORR), including MRD negativity
Timepoint [6] 324608 0
Patients will be assessed for ORR monthly during consolidation treatment, then every 3 months following disease progression or C13 onwards. ORR will be determined by tabulating each patient's disease response according to the IMWG uniform response criteria. OR is defined as the achievement of a partial response (PR) or better on study.
Secondary outcome [7] 324612 0
To determine the tolerability (measured by performance status (Eastern Cooperative Oncology Group scale)) of ixazomib in combination with thalidomide and low dose dexamethasone consolidation therapy post-ASCT in MM patients.
Timepoint [7] 324612 0
Ongoing analysis from registration to end of follow up period (60 months). Study parameters include documentation of medication administered, adverse events (as per the Common Terminology Criteria for Adverse Events, CTCAE v4.0), and dose adjustments.
