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 subject; (periodic abstinence [e.g., calendar, ovulation,
symptothermal, post-ovulation methods] and withdrawal are not acceptable methods
of contraception)
- Male patients, even if surgically sterilized (i.e., 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

usual lifestyle of the subject; (periodic abstinence [e.g., calendar, ovulation,
symptothermal, post-ovulation methods] and withdrawal are not acceptable methods
of contraception)
- Patients must have a diagnosis of one of the following B-NHL malignancies: chronic
lymphocytic leukemia (CLL)/ small lymphocytic lymphoma (SLL), follicular lymphoma
(FL), mantle cell lymphoma (MCL), marginal zone lymphoma (MZL), or Waldenstrom
macroglobulinemia (WM)/ lymphoplasmacytic lymphoma (LPL); patients with mucosa
associated lymphoid tissue (MALT) subtype of MZL may have relapsed or refractory
disease after a course of antibiotic therapy; otherwise, patients will not have
received standard systemic treatment for their B-NHL before the time of study
enrollment; standard systemic therapy is defined by including any of the following
agents, representing a comprehensive list of recommended front-line agents used in the
treatment of B-NHL: cytotoxic chemotherapies (bendamustine, cyclophosphamide,
doxorubicin, vincristine, chlorambucil, cytarabine, gemcitabine, platinum drugs,
etoposide); anti-CD20 antibodies (obinutuzumab, ofatumumab, rituximab); lenalidomide;
ibritumomab tiuxetan; proteasome inhibitors (bortezomib, carfilzomib); tyrosine kinase
inhibitors (ibrutinib, acalabrutinib, idelalisib); alemtuzumab; corticosteroids unless
given for an indication other than treating the B-NHL; or other therapy as determined
by the principal investigator (PI)

purpura); platelet transfusions to help patients meet eligibility criteria are not
allowed within 3 days before study enrollment
- Total bilirubin =<1.5 x the upper limit of the normal range (ULN)

according to published guidelines by the National Comprehensive Cancer Network (NCCN)
- Patients must have measurable disease defined by at least one of the following
criteria:
- Lesions greater than 1.5 cm that can be accurately measured in two dimensions by
computed tomography (CT) (preferred), or magnetic resonance imaging (MRI), and
are not included in any prior field of radiation given to treat B-NHL
- In patients with CLL, circulating lymphocytes >= 5,000 / mm^3
- In patients with WM/LPL, measurable serum monoclonal immunoglobulin M (IgM)
Exclusion Criteria:
- Female patients who are lactating or have a positive serum pregnancy test during the
screening period

hypertension, cardiac arrhythmias, or congestive heart failure, and unstable angina or
myocardial infarction within the past 6 months
- Systemic treatment, within 14 days before the first dose of ixazomib, with strong
inhibitors of cytochrome P450, family 1, subfamily A, polypeptide 2 (CYP1A2)
(fluvoxamine, enoxacin, ciprofloxacin), strong inhibitors of cytochrome P450, family
3, subfamily A (CYP3A) (clarithromycin, telithromycin, itraconazole, voriconazole,
ketoconazole, nefazodone, posaconazole) or strong CYP3A inducers (rifampin,
rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of ginkgo
biloba or St. John's wort
- Known ongoing or known active systemic infection, known active hepatitis B or C virus
infection, or known human immunodeficiency virus (HIV) positive
