Brief summary: The main aim is to evaluate the effect of Ixazomib in combination with lenalidomide and dexamethasone on Multiple Myeloma disease progression at 2 years in participants who previously received a bortezomib-based induction regimen.

The study will enroll approximately 160 participants, who are enrolled after completing 3 cycles of chemotherapy (Bortezomib-Based Induction Regimen). They are then treated with Ixazomib in addition to lenalidomide and dexamethasone.

Detailed description: The drug being tested in this study is called Ixazomib. Ixazomib is being tested to treat people who have MM. This study will look at the effectiveness and safety in participants who take the all-oral combination of ixazomib added to lenalidomide and dexamethasone.

The study will enroll approximately 160 participants. Participants will initially receive:

• Ixazomib 4 mg + lenalidomide 25 mg + dexamethasone 40 mg

Participants include MM participants who have received 3 cycles of a bortezomib-based induction regimen (as defined by current National Comprehensive Cancer Network \[NCCN\] guidelines) and have no evidence of PD following initial first-line therapy. All participants will be asked to take ixazomib 4 mg on Days 1, 8 and 15 and lenalidomide 25 mg from Day 1 through 21 and dexamethasone 40 mg on Days 1, 8, 15 and 22 in 28 day cycles until disease progression or unacceptable toxicity for up to 3 years.

Dose modifications of ixazomib, and/or lenalidomide and/or dexamethasone are allowed at the discretion of the physician.

This multi-center trial will be conducted in United States. It is anticipated that the treatment phase of this study will last up to 78 months, including 42 months for enrollment, and a 36-month IRD treatment period (39 cycles) with ixazomib and/or lenalidomide and/or dexamethasone for the last participant enrolled.

Participants will make multiple visits to the clinic as per their standard of care, and will be followed for PFS. After disease progression, participants will be followed-up for overall survival every 6 months until death or termination of the study by the sponsor.

Eligibility criteria: Inclusion Criteria:

1. Must have a diagnosis of a MM using current IMWG diagnostic criteria and have received 1 prior line of therapy.

   * Participants must have completed 3 cycles of a bortezomib-based induction regimen (as defined by current NCCN guidelines) and have no evidence of disease progression as defined by IMWG criteria.
   * Participants with light chain and free light chain (FLC) only may be enrolled if they meet all the criteria for a diagnosis of MM.
   * Participants must be considered by their physician eligible to receiving the IRD regimen.
2. Must be transplant ineligible as determined by their physician, or if transplant eligible, not expect to undergo transplant for at least 24 months after study enrollment.

   o Stem cell harvest and mobilization regimen is acceptable if clinically indicated, but must first be confirmed by the Takeda Medical Monitor.
3. Eastern Cooperative Oncology Group (ECOG) performance status and/or other performance status 0, 1, or 2 at time of enrollment.
4. Female participants who:

   * Are postmenopausal for at least 1 year before the screening visit, OR
   * Are surgically sterile, OR
   * If they are of childbearing potential, agree to practice 2 effective methods of contraception, at the same time, from the time of signing the informed consent form through 90 days after the last dose of study drug, OR
   * Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the participant (periodic abstinence \[example, calendar, ovulation, symptothermal, post-ovulation methods\] and withdrawal are not acceptable methods of contraception).
5. Male participants, even if surgically sterilized (that is, status post-vasectomy), must agree to one of the following:

   * Agree to practice effective barrier contraception during the entire study treatment period and through 90 days after the last dose of study drug, OR
   * Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the participant. (Periodic abstinence (example, calendar, ovulation, symptothermal, post-ovulation methods\] and withdrawal are not acceptable methods of contraception).

Exclusion Criteria:

1. Participation in other interventional clinical trials, including those with other investigational agents not included in this trial, within 30 days of the start of this trial and throughout the duration of this trial. Non-interventional trials (that is, observational trials) are permitted at any time point.
2. Failure to have fully recovered (that is, less than or equal to \[\<=\] Grade 1 toxicity) from the reversible effects of prior chemotherapy.
3. Major surgery within 14 days before enrollment.
4. Radiotherapy within 14 days before enrollment (if the involved field is small, 7 days will be considered a sufficient interval between treatment and administration of the ixazomib).
5. Central nervous system involvement by MM.
6. Infection requiring systemic antibiotic therapy or other serious infection within 14 days before study enrollment.
7. Evidence of current uncontrolled cardiovascular conditions, including uncontrolled hypertension, uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, or myocardial infarction within the past 6 months.
8. Systemic treatment, within 14 days before the first dose of ixazomib, with strong cytochrome P450 3A (CYP3A) inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of Ginkgo biloba or St. John's wort.
9. Ongoing or active systemic infection, active hepatitis B or C virus infection, or known human immunodeficiency virus positive.
10. Diagnosed or treated for another malignancy within 2 years before study enrollment or previously diagnosed with another malignancy and have any evidence of residual disease. Participants with nonmelanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection.
11. Has greater than or equal to (\>=) Grade 2 peripheral neuropathy, or Grade 1 with pain on clinical examination during the screening period.
12. Have previously been treated with ixazomib, or participated in a study with ixazomib whether treated with ixazomib or not.
13. PD on first-line therapy.
