E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The principal research question for randomisation one focuses on whether a scoring system, the IMWG frailty index, can determine frailty in trial participants. Half of the participants are assigned different doses of treatment. The scoring system takes into account the participant's age, other illnesses and whether they can live independently to determine how frail they are, giving them both a frailty score and a category (fit, unfit, frail). The scoring system will be measured by comparing the number of participants who stop trial treatment for any reason within 60 days of randomisation one between the two arms; standard dosing (standard of care) and frailty-score adjusted dosing.
If a patient is still alive and disease progression-free after 12 cycles of treatment they will be randomised again to receive either lenalidomide and placebo or lenalidomide and ixazomib. The principal research question for the randomisation two is to determine whether the addition of ixazomib to lenalido |
|
E.2.2 | Secondary objectives of the trial |
The secondary research questions are:- For randomisation one: • the time from randomisation one to progression or death • the number of participant’s dying within 12 months of randomisation one • patient’s response to treatment • the length of the response to treatment • the time until the participant requires a new non-trial anti-myeloma treatment.
For randomisation two: • the time it takes for a patient’s response to treatment improve.
The secondary objectives for randomisation one are to assess the frailty score adjusted dosing strategy in terms of: • Progression-free survival (PFS) • Time to progression • Time to 2nd PFS event (PFS2) • Overall Survival (OS) • Survival after progression • Deaths within 12 months of R1 • Overall response rate (ORR) • Attainment of ≥VGPR • Attainment of Minimal Residual Disease (MRD) negativity • Duration of response (DoR) • Time to next treatment • Treatment compliance and total amount of therapy delivered • Toxicity & safety, including the incide |

E.5 End points |
E.5.1 | Primary end point(s) |
R1: Early treatment cessation Early treatment cessation is defined as a binary endpoint. Participants will be defined to have experienced an event if they die, progress, or are withdrawn from treatment (by a treating clinician) or withdraw consent for trial treatment, within 60 days of R1. R2: Progression-free survival (PFS-R2) PFS-R2 is defined as the time from R2 to the time of first documented evidence of disease progression or death from any cause. Individuals who are lost to follow-up or progression-free at the time of analysis will be censored at their last known date to be alive and progression-free.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Both primary outcome measures will be evaluated at their interim analysis and when all participants have reached the required time point. For R1 the interim will be when 370 participants have reached 60 days post-R1 and the final analysis will be when all 740 participants have reached 60 days post-R1. For R2 the interim analysis will take place when 151 patients have progressed or died following R2 and the final analysis will take place when 252 patients have progressed or died following R2 and it is at least two-years following the randomisation of the last participant into R2. |
|
E.5.2 | Secondary end point(s) |
Progression-free survival (PFS-R1) PFS-R1 is defined the same as the primary endpoint PFS-R2 but measured from randomisation 1 instead of randomisation 2.
Time to progression Time to disease progression is defined for both R1 and R2 as the time from randomisation to the date of first documented evidence of disease progression. Participants who die prior to documentation of disease progression will be censored in the analysis at their 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. Participants dying from causes not primarily due to progression will also be censored.
Progression-free survival two (PFS2) For both R1 and R2, progression-free survival two is defined as the time from randomisation to the time of the second documented disease progression or death from any cause. Individuals who are lost to follow-up or alive and second progression-free at the time of analysis will be censored at their last known date to be alive and second progression-free.
Overall survival (OS) Overall survival is defined separately for each randomisation. In each case it is the time from randomisation to the time of death from any cause. Individuals who are lost to follow-up or still alive at the time of analysis will be censored at their last known date to be alive.
Survival after progression Survival after progression is defined from the date of first documented evidence of disease progression to the date of death from any cause. Individuals who are lost to follow-up or alive at the time of analysis will be censored at their last known date to be alive following their first documented evidence of disease progression.
Deaths within 12 months of R1 Deaths within 12 months of R1 is defined as a binary endpoint. Participants will be defined to have experienced an event if they die within 12 months of R1.
Overall response rate (ORR) Overall response rate is defined as a categorical outcome consisting of whether a participant had sCR, CR, VGPR, PR, MR, SD or PD at the end of induction.
Attainment of ≥VGPR Attainment of ≥VGPR is defined as a binary outcome of whether a participant had ≥VGPR (VGPR, CR, sCR) or <VGPR (PR, MR, SD, PD) at the end of induction.
Attainment of Minimal Residual Disease (MRD) negativity Attainment of Minimal Residual Disease (MRD) negativity is defined as a binary endpoint. MRD negativity will be determined at the end of induction therapy and 12 months post R2.
Duration of response (DoR) Duration of response is defined as the time from the first observation of response ≥ PR, following R1, to the time of first documented evidence of disease progression or death confirmed related to progression. Individuals who are lost to follow-up, or still alive and progression-free at the time of analysis will be censored at their last known date to be alive and progression-free. Individuals whose cause of death is unrelated to disease progression will be censored at their date of death.
Time to improved response Time to improved response is defined as the time from the date of R2 to the date the response category is first improved. Subjects without any improvement of the baseline status at R2 will be censored at the last date of response assessment.
Time to next treatment Time to next treatment is defined as the time from R1 to the start date of the next line of treatment or death from any cause.
Treatment compliance and total amount of therapy delivered In the first instance treatment compliance is defined as a binary outcome i.e. did the participant receive 12 cycles of induction treatment. The total amount of therapy delivered will be first defined as the number of induction and maintenance cycles which the participant received. This may be extended to consider the percentage of protocol dose delivered. For each treatment (ixazomib, lenalidomide, dexamethasone) this will be defined as the total dose received in a cycle compared to the total dose the participant should have received in the cycle without modifications, averaged across all cycles of treatment.
Toxicity & safety, including incidence of second malignancies Toxicity and safety will be reported based on the adverse events, as graded by CTCAE V5 and determined by routine clinical assessments. The number of SAEs will be reported according to MedDRA System Organ Class. All second primary malignancies will be reported based on information recorded.
Quality of Life (QoL) Quality of Life is defined using the patient-reported outcome measures; EORTC-QLQ-C30, EORTC-QLQ-MY20 and EQ-5D (3 Level).
Cost effectiveness of delivery of IRD and R+I Cost-effectiveness is defined as a cost per incremental QALY below £20,000 and/or a positive incremental net monetary benefit. This will compare the cost-effectiveness of the intervention to the control for each of the randomisations separately.

E.5.2.1 | Timepoint(s) of evaluation of this end point |
