Inclusion Criteria

Adult patients (aged =18 years) who have been diagnosed with multiple myeloma (MM) according to standard criteria.
All patients must have had a relapse or PD after having received 2 or more prior lines of systemic therapy. (A line of therapy is defined as 1 or more cycles of a planned treatment program; this may consist of 1 or more planned cycles of single-agent therapy or combination therapy, as well as a sequence of treatments administered in a planned manner. For example, a planned treatment approach of induction therapy followed by autologous stem-cell transplantation, followed by maintenance is considered 1 line of therapy. Typically each line of therapy is separated by PD.)
All patients must be refractory to lenalidomide, defined as having received at least 2 consecutive cycles of lenalidomide as a single agent or within a lenalidomide-containing regimen and having had PD during treatment with or within 60 days after the last dose of lenalidomide. The starting dose of lenalidomide should have been 25 mg (or as low as 10 mg in the case of renal function impairment or other safety concern), and the final dose should
have been a minimum of 10 mg.
All patients must have received at least 2 consecutive cycles of a bortezomib- or carfilzomib-containing regimen, and either:
– Achieved at least a partial response (PR) and did not have PD during treatment with or within 60 days after the last dose of bortezomib or carfilzomib, OR
– Had bortezomib and/or carfilzomib intolerance (defined as discontinuation because of drug-related adverse events (AEs) before completion of the planned treatment course) without PD upon the start of the next regimen.
All patients must have an Eastern Cooperative Oncology Group score of 0 to 2.
All patients must have measurable disease defined by serum M-protein =1 g/dL (=10 g/L) or urine M-protein =200 mg/24 hours and must have documented MM isotype by immunofixation (central laboratory).

Exclusion Criteria

Patients meeting any of the following exclusion criteria are not to be enrolled in the study:
- Patients must not have received prior ixazomib or pomalidomide and must not have been a participant in a previous ixazomib clinical study.
- Prior allogenic bone marrow transplantation in any prior line of therapy
or prior autologous
SCT in the last prior line of therapy—unless the autologous SCT was
performed a year or more
before disease progression.
- Female patients who are lactating and breastfeeding or have a positive
serum pregnancy test
during the Screening period.
- Any serious medical or psychiatric illness that could, in the
investigator's opinion, potentially
interfere with the completion of treatment according to this protocol,
such as life-threatening
illness unrelated to cancer.
- Diagnosed with or treated for another malignancy within 2 years before randomization, or previously diagnosed with another malignancy and have any evidence of
residual, persistent, or recurrent disease. Patients with nonmelanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection.
- Diagnosis of smoldering MM (see Appendix D), Waldenström's macroglobulinemia, POEMS
(polyneuropathy, organomegaly, endocrinopathy, monoclonal
gammopathy, and skin
changes) syndrome, plasma cell leukemia, primary amyloidosis,
myelodysplastic syndrome,
or myeloproliferative syndrome.
- Known allergy to any of the study medications or their analogues, or
excipients in the various
formulations.
- Peripheral neuropathy Grade 1 with pain or Grade 2 or higher
peripheral neuropathy of any
cause on clinical examination during the Screening period.
- Treatment with any investigational products or with chimeric or fully
human monoclonal
antibodies within 30 days before randomization, systemic anticancer
therapy or radiotherapy
within 14 days before randomization (Note: spot radiation for areas of
pain is permitted), and major surgery within 14 days before
randomization.
- Known gastrointestinal disease or gastrointestinal procedure that could
interfere with the oral absorption or tolerance of study therapy,
including difficulty swallowing.
- Serious infection requiring parenteral antibiotic therapy or any other
serious infection within 14 days before randomization.
- Central nervous system involvement with MM (by clinical symptoms
and signs).
- Ongoing or active systemic infection, known human immunodeficiency
virus-RNA positive,
known hepatitis B surface antigen seropositive, or known hepatitis C
virus-RNA positive.
Note: Patients who have positive hepatitis B core antibody can be
enrolled but must have
hepatitis B virus-DNA negative. Patients who have positive hepatitis C
antibody can be
enrolled but must have hepatitis C virus-RNA negative.
- Systemic treatment with strong cytochrome P-450 3A inducers
(rifampin, rifapentine,
rifabutin, carbamazepine, phenytoin, phenobarbital) or use of St. John's
wort within 14 days
before randomization.
- Admission or evidence of illicit drug use, drug abuse, or alcohol abuse.
- History of severe cutaneous reactions, including hypersensitivity
reactions such as
Stevens-Johnson syndrome (SJS), Toxic Epidermal Necrolysis (TEN), and
Drug
Reaction with Eosinophilia and Systemic Symptoms (DRESS), in the
context of
treatment with lenalidomide or thalidomide (see Section 8.7 of protocol
for more information).
