MRD was measured by the flow cytometry method using bone marrow aspiration. Reported data were numbers of participants with MRD positive and negative in bone marrow in participants who achieved CR. MRD positive was categorized into three sensitivity levels with the numbers of cells counted (10\^-4 to - Max; 10\^-5 to 10\^-4; 10\^-6 to 10\^-5). MRD negativity is defined as absence of MRD and MRD positivity is defined as presence of MRD. If a participant is MRD-positive at their first evaluation and MRD-negative after re-examination, the participant will be considered to be MRD-negative. CR will be assessed by IMWG Criteria.

EORTC QLQ-C30 contains 30 items across 5 functional scales (physical, role, cognitive, emotional, and social), 9 symptom scales (fatigue, nausea and vomiting, pain, dyspnea, sleep disturbance, appetite loss, constipation, diarrhea, and financial difficulties) and a global health status/QOL scale (Global Health Status). EORTC QLQ-C30 contains 28 questions (4-point scale where 1=Not at all \[best\] to 4=Very Much \[worst\]) and 2 questions (7-point scale where 1=Very poor \[worst\] to 7= Excellent \[best\]). Raw scores are converted into scale scores ranging from 0 to 100. For the functional scales and the global health status/QOL scale, higher scores represent better QOL; for the symptom scales, lower scores represent better QOL.

Full study description

brief Summary: The purpose of this study is to investigate the efficacy and safety of long-term administration of the oral proteasome inhibitor ixazomib as part of ixazomib in combination with lenalidomide and dexamethasone (IRd) therapy in patients with relapsed and/or refractory multiple myeloma (RRMM) treated initially with an injectable proteasome inhibitor-based therapy.
detailed Description: The drug being tested in this study is called Ixazomib. Ixazomib is being tested to treat people who have RRMM. This study will look at the effectiveness and safety of IRd in participants with RRMM previously receiving an injectable proteasome inhibitor-based therapy. This study consists of two treatment periods, Treatment Period I and Treatment Period II. The study will enroll 47 patients. All participants will receive following treatment: \- Combination therapy with Bortezomib + Lenalidomide + Dexamethasone (VRd) or combination therapy with Carfilzomib + Lenalidomide + Dexamethasone (KRd), standard recommended dose according to the package insert of each drug, as Treatment Period I, followed by Combination therapy with Ixazomib 4.0 mg + Lenalidomide 25 mg + Dexamethasone 40 mg (IRd) as Treatment Period II At start of this study, combination therapy of VRd or KRd will be decided by investigator as Treatment Period I after the baseline evaluations. After the start of Treatment Period I, a participant's eligibility for Treatment Period II is then determined 3 cycles. Participants who meet these eligibility criteria II subsequently continue into Treatment Period II and receive IRd. This multi-center trial will be conducted in Japan. It is anticipated that the treatment phase of this study will last up to 39 months, including 18 months for enrollment. Participants will make multiple visits to the clinic in treatment period, and follow-up period including a follow-up assessment after last dose of study drug.
