Brief Summary:
The purpose of this study is to determine the effect of ixazomib maintenance therapy on progression free survival (PFS) compared with placebo, in participants with NDMM who have had a major response (complete response [CR], very good partial response [VGPR], or partial response [PR]) to initial therapy and who have not undergone SCT.

Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: Ixazomib Drug: Placebo Phase 3

Detailed Description:

The drug being tested in this study is called ixazomib citrate. Ixazomib citrate is being tested to slow PD and improve overall survival in people who have NDMM who have had a major positive response to initial therapy and have not undergone SCT. This study will look at the effect of ixazomib citrate has on the length of time that participants are free of PD and their overall survival.

The study will enroll approximately 700 participants. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need):

  • Ixazomib citrate 3 mg
  • Placebo (dummy inactive pill) - this is a capsule that looks like the study drug but has no active ingredient

All participants will be asked to take one capsule on Days 1, 8 and 15 of each 28-day cycle, for up to 26 cycles.

This multi-center trial will be conducted worldwide. The overall time to participate in this study is approximately 76 to 104 months. Participants will make 28 visits to the clinic during the treatment period and will continue to make follow-up visits every 4 weeks until the next line of therapy begins. Participants will also be contacted by telephone every 12 weeks after last treatment visit for a follow-up assessment.

The EORTC QLQ-30 contains 30 questions that incorporate 5 functional scales (physical functioning, role functioning, emotional functioning, cognitive functioning, and social functioning), 1 global health status scale, 3 symptom scales (fatigue, nausea and vomiting, and pain), and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). The participant answers questions about their health during the past week. There are 28 questions answered on a 4-point scale where 1 =Not at all (best) to 4 =Very Much (worst) and 2 questions answered on a 7-point scale where 1 =Very poor (worst) to 7 =Excellent (best).

  16. Number of Participants with any Markedly Abnormal Standard Safety Laboratory Values [ Time Frame: From First dose date of study drug through 30 days after the last dose of study drug (Up to 25 months) ]

  17. Correlation between Frailty Status and PFS and OS [ Time Frame: Up to approximately 76 to 104 months ]
    Participant's frailty status is classified as fit, unfit or frail on the bases of 4 components: age, the Charlson comorbidity scoring system without age weighting, the Katz index of independence in activities of daily living, and the Lawton instrumental activities of daily living scale. The sum of the 4 frailty scores equals the total frailty score. A total frailty score of 0 corresponds to a frailty status of fit; a total score of 1, to unfit; and a total score of 2 or more, to frail. PFS is defined as the time from the date of randomization to the date of first documentation of PD or death from any cause, as evaluated by an IRC according to IMWG criteria, or death due to any cause, whichever occurs first. OS will be measured as the time from the date of randomization to the date of death.

    Plasma concentrations of the complete hydrolysis product of ixazomib citrate (ixazomib) will be measured using a validated Liquid Chromatography-tandem Mass Spectrometry (LC/MS/MS) assay.

  19. Time to Resolution of Peripheral Neuropathy (PN) Events [ Time Frame: From the initial onset date of PN up to the resolution date for resolved events (Up to 25 Months) ]
    PN is defined as the treatment-emergent adverse event in the high-level term of peripheral neuropathies not elsewhere classified (NEC) according to the Medical Dictionary for Regulatory Activities (MedDRA). A PN event is considered as resolved if its final outcome is resolved with no subsequent PN event of the same preferred term occurring on the resolution date or the day before and after. Time to resolution is defined as the time from the initial onset date (inclusive) to the resolution date for resolved events.

  20. Time to Improvement of PN Events [ Time Frame: From the initial onset date of PN up to the improvement of event (Up to 25 Months) ]
    PN is defined as the treatment-emergent adverse event in the high-level term of peripheral neuropathies NEC according to the MedDRA. A PN event is considered as resolved if its final outcome is resolved with no subsequent PN event of the same preferred term occurring on the improvement date or the day before and after. Time to improvement is defined as the time from the initial onset date (inclusive) to the improvement of event.
