• Demographic Characteristics of Multiple Myeloma (MM) Participants [ Time Frame: Baseline ]
  Demographic characteristics (such as age, gender, race, ethnicity, country of residence, and health insurance) of MM participants will be assessed at baseline.
• Number of Participants with Comorbid Conditions [ Time Frame: Baseline ]
  Number of participants with comorbid conditions (such as obesity, diabetes, cardiovascular disease, anemia alcohol, and tobacco use) will be assessed at baseline.
• General Health Status Based on Frailty Score [ Time Frame: Approximately up to 2.7 years ]
  General health status based on Frailty Score will be reported. International Myeloma Working Group (IMWG) frailty score: Participants frailty status will be assessed on the basis of 4 components: age (less than [<75], 76- 80, and greater than [>]80 years correspond to frailty scores of 0, 1, and 2, respectively), the charlson comorbidity scoring system without age weighting (scores of less than or equal to [<=]1 and greater than or equal to [>=]2 correspond to frailty scores of 0 and 1, respectively), independence in activities of daily living (scores of >4 and <=4 correspond to frailty scores of 0 and 1, respectively) and instrumental activities of daily living scale (scores of >5 and <=5 correspond to frailty scores of 0 and 1, respectively). The sum of the 4 frailty scores equals the total frailty score. The total frailty score ranges from 0 to 5, with a total of three categories: 0 (fit), 1 (intermediate-fitness) and greater than or equal to (>=)2 (frail).
• Eastern Cooperative Oncology Group (ECOG) Performance Status Score [ Time Frame: Approximately up to 2.7 years ]
  ECOG performance status is a standard criterion for measuring how the disease impacts daily living abilities. It describes the level of functioning in terms of the ability to care for oneself, daily activity, and physical ability (walking, working, etc). ECOG performance status score ranges from Grade 0 to 5: 0= Fully active and performances without restriction, 1= Restricted in physically strenuous activity, 2= Ambulatory and capable of all self-care but unable to carry out any work activities, 3= Capable of only limited self-care and confined to bed or chair more than 50% of waking hours, 4= Completely disabled, and 5= Dead.
• Sequence of Treatments in Participants with Multiple Myeloma (MM) [ Time Frame: Approximately up to 2.7 years ]
  Treatment sequences for participants with MM within routine clinical care will be assessed.
• Number of Participants in Each Stage of Multiple Myeloma (MM) Disease [ Time Frame: Approximately up to 2.7 years ]
  Number of participants in each stage of MM disease will reported. The stage of MM disease will be determined by International Staging System (ISS). ISS categorizes MM participants into three groups (Stage I, II, or III). Stage I: beta2-microglobulin less than (<)3.5 milligram per liter (mg/L) and albumin greater than or equal to (>=)3.5 gram (g)/100 milliliter (mL); stage II: neither stage I nor stage III; and stage III: beta2-microglobulin >=5.5 mg/L.

• Overall Survival (OS) [ Time Frame: Approximately up to 2.7 years ]
  The OS in MM participants will be measured and reported from diagnosis to the date of death.
• Progression-Free Survival (PFS) [ Time Frame: Approximately up to 2.7 years ]
  PFS is defined as time from diagnosis to disease progression. IMWG criteria for disease progression: increase of greater than or equal to (>=)25 percent (%) from lowest response value in any one of the following: Serum M-component (absolute increase must be >=0.5 gram per deciliter [g/dL]), Urine M-component (absolute increase must be >=200 milligram per 24 hour [mg/24 hour]), only in participants without measurable serum and urine M-protein levels: the difference between involved and uninvolved free light chain levels (absolute increase must be greater than >10 mg/dL), Bone marrow plasma cell percentage: the absolute percent must be >=10%, Definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas, Development of hypercalcemia (corrected serum calcium >11.5 mg/dL or 2.65 millimoles per liter [mmol/L]) that can be attributed solely to the plasma cell proliferative disorder.
• Percentage of Participants with Complete Response (CR) [ Time Frame: Approximately up to 2.7 years ]
  Complete response (CR) per International Myeloma Working Group (IMWG 2014) criteria is defined by negative immunofixation on the serum and urine, disappearance of any soft-tissue plasmacytomas, and less than (<)5 percent (%) plasma cells in bone marrow.
• Percentage of Participants with Stringent Complete Response (sCR) [ Time Frame: Approximately up to 2.7 years ]
  Stringent CR per IMWG criteria is defined by a below plus normal fee-light-chain (FLC) ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence.
• Duration of Response [ Time Frame: Approximately up to 2.7 years ]
  Duration of response is defined as the time from the date of initial documentation of a response (CR or partial response [PR]) to the date of first documented evidence of progressive disease (or relapse for participants who experience CR during the study) or death. Relapse as per IMWG criteria is defined as presence of definite new bone lesions and/or soft-tissue plasmacytomas, with a clear increase in the size of existing plasmacytomas, or hypocalcemia that cannot be attributed to another cause.
• Time to Next Treatment [ Time Frame: Approximately up to 2.7 years ]
  Time to next treatment is defined as the time from diagnosis to the start of the next-line treatment.
• Percentage of Participants who Adopted Treatment Regimens [ Time Frame: Approximately up to 2.7 years ]
  Percentage of participants who adopted treatment regimens will be reported.
• Number of Participants with Adverse Events [ Time Frame: Approximately up to 2.7 years ]
  An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.
• Number of Participants who Underwent Different Types of Minimal Residual Disease (MRD) Tests [ Time Frame: Approximately up to 2.7 years ]
  Number of participants who underwent different types of MRD tests will be reported. MRD tests include next-generation [NG] flow cytometry, NG sequencing, positron emission tomography with computed tomography [PET-CT].
