Detailed Description
The drug being tested in this study is called Ixazomib. Ixazomib is being tested to treat people who have relapsed and/or refractory multiple myeloma (RRMM) under the conditions of standard medical care. This study is a non-interventional (observational), domestic, multicenter, prospective study in patients with RRMM. This study will look at the effectiveness and safety of ixazomib in combination with lenalidomide and dexamethasone in Japanese patients with RRMM as standard medical care. In addition, an exploratory study of biomarkers will be conducted in this study.
The study will enroll approximately 300 patients. All participants will receive Ixazomib + Lenalidomide + Dexamethasone (IRd) therapy as standard medical care.
This multi-center trial will be conducted in Japan. The overall time of observational period in this study will be 36 months. For each participant, the observation period will be from the start of IRd therapy until either 24 months after the enrollment date of the final patient to enroll, or until death or withdrawal of consent, whichever is earlier.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Progression-Free Survival (PFS)
Time Frame: Up to 36 Months as a maximum
|
PFS was defined as the period from the start of ixazomib, lenalidomide, dexamethasone (IRd) therapy in standard medical care to the time of confirmed progressive disease (PD) or confirmed death (regardless of the cause of death), whichever was earlier.
PFS was assessed by International Myeloma Working Group (IMWG) Criteria (2014 version).
Per IMWG criteria, PD: serum M-component increase ≥ 0.5 g/dl or urine M-component increase ≥ 200 mg/24-hour/ difference between involved and uninvolved free light chain (FLC) levels increase >10 mg/dl or bone marrow plasma cell ≥ 10%/ development of new/ increase in size of existing bone lesions or soft tissue plasmacytoma or development of hypercalcemia.

Time Frame: Baseline and End of Treatment (Up to 37 cycles, each cycle was of 28 days)
|
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.
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 of Global Health Status in EORTC QLQ-C30 were linearly transformed to a total score between 0-100 and reported, with a high score indicating better QOL.

Scores are averaged, and transformed to 0-100 scale.
For the future perspective scale, higher score = better perspective of the future.
For the body image scale, higher scores = better body image.
Higher score for the disease symptoms scale = higher level of symptomatology.
