The main aim of this study is to check side effects and results in adults with multiple myeloma after switching from a bortezomib/carfilzomib -based to an Ixazomib-based treatment.
This is a non-interventional, prospective study of participants with multiple myeloma (MM). Participants will be treated with ixazomib based regimens until progression or unacceptable toxicity leading to a discontinuation or change in regimen, for a maximum of 26 cycles (24 months) (as per NINLARO® label) in real world clinical setting. The study will enroll approximately 80 participants. The data will be collected prospectively in medical charts and will be recorded into electronic case report forms (eCRFs). All the participants will be assigned to a single observational cohort: • Participants with MM This multi-center trial will be conducted in China. The overall time for data collection in the study will be 24 months. Participants will be followed once every 3 months for a period not exceeding 24 months, ending 12 months after the last participant's enrollment unless withdraw of informed consent form, death or lost to follow-up, termination of the study by the sponsor, whichever comes first.

Progression Free Survival (PFS) at 24 Months
PFS:time date of first administration of ixazomib therapy to date of first documentation of progressive disease(PD)/death,lost to follow-up,whichever occurs first as per IMWG 2016 Response Criteria.PD:increase of 25 percent(%) from lowest confirmed response value in any one/more of following:Serum and Urine M-protein only in participants without measurable serum and urine M-protein levels,difference between involved/uninvolved free light chain (FLC) levels(absolute increase greater than(\>)10 milligram per deciliter \[mg/dL\]),and without measurable involved FLC levels, bone marrow plasma-cell% irrespective of baseline status (absolute increase must be ≥10%); appearance of new lesions, ≥50% increase from nadir in SPD of \>1 lesion/ ≥50% increase in the longest diameter of a previous lesion \>1 centimeter in short axis; ≥50% increase in circulating plasma cells (minimum of 200 cells per microliter \[mcL\]) if this is the only measure of disease. It will be analyzed using Kaplan-Meier method.
Time frame: From the date of first administration of ixazomib therapy to the date of first documentation of PD or death, lost to follow-up, whichever occurs first (up to 24 months)
Time to Next Treatment (TTNT)
Time to next treatment will be defined as the time from the date of the first administration of ixazomib therapy to first dose of new treatment given after changing the therapy.
Time frame: From the date of the first administration of ixazomib therapy to first dose of new treatment (up to 24 months)
Percentage of Participants Achieving Very Good Partial Response (VGPR)
VGPR will be assessed as per IMWG 2016 Response Criteria, and defined as: Serum and urine M-protein detectable by immunofixation but not on electrophoresis or greater than or equal to (\>=) 90% reduction in serum M-protein plus urine M-protein level less than (\<) 100 milligram (mg) per 24 hour (h).
Time frame: Up to 24 months

CR will be assessed as per IMWG 2016 Response Criteria and defined as: Negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and \<5% plasma cells in bone marrow aspirates. For participants who only rely on serum FLC level as measurable lesions, in addition to meeting the above CR criteria, the ratio of serum FLC should return to normal under two consecutive assessments.
Time frame: Up to 24 months
Percentage of Participants Achieving Stringent Complete Response (sCR)
sCR will be assessed as per IMWG 2016 Response Criteria, and defined as: Negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and \<5% plasma cells in bone marrow aspirates. For participants who only rely on serum FLC level as measurable lesions, in addition to meeting the above CR criteria, the ratio of serum FLC should return to normal under two consecutive assessments. Absence of clonal plasma cells in bone marrow biopsy by immunohistochemistry. Presence of bone clonal plasma cells is defined as κ/λ \>4:1 or \<1:2 ratio under two consecutive detection by immunohistochemical method (for participants with type κ and type λ respectively, and requiring a minimum of 100 plasma cells for analysis).
Time frame: Up to 24 months
Duration of Ixazomib Therapy (DOT)
DOT will be defined as the time from the date of the first administration of ixazomib therapy to the date of the last administration of ixazomib therapy.
Time frame: Up to 24 months
Duration of CR
Duration of CR will be defined as time from first documented CR to the date of PD as per IMWG 2016 Response Criteria.
Time frame: Up to 24 months
Overall Survival (OS)
OS will be defined as the time from enrollment to death from any cause.

Health-related Quality of Life (HRQOL) Based on European Organization for Research and Treatment of Cancer Multiple Myeloma Module (EORTC QLQ-MY20)
EORTC QLQ-MY20 is self-administered patient-reported outcomes (PRO) used to assess quality of life during the last 7 days. It has 20 items evaluated on 4 point rating scale ranging from: 1 (not at all), 2 (a little), 3 (quite a bit), 4 (very much). Total score ranges from 20 to 80. Higher scores represent worsening.
Time frame: Up to 24 months
HRQOL Based on EORTC QLQ-C30
EORTC QLQ-C30 is self-administered PRO which 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/quality of life (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 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.
Time frame: Up to 24 months
Treatment Satisfaction Questionnaire for Medication (TSQM-9)
TSQM-9 is self-administered PRO. It is a 9-item, validated, self-administered instrument used to assess participant's satisfaction or dissatisfaction with medication. The three domains assessed are effectiveness, convenience, and global satisfaction. The score of each of the 3 domains is based on an algorithm to create a score of 0 to 100. Higher score indicated greater satisfaction in that domain.
