Alternating the Administration of Ixazomib and Lenalidomide as Maintenance Therapy After Autologous Transplant for Treating Multiple Myeloma

This phase II trial studies the safety of alternating ixazomib citrate and lenalidomide as
treatment to help keep cancer from coming back after stem cell transplant (maintenance
therapy) in treating patients with multiple myeloma. Ixazomib citrate may stop the growth of
cancer cells by blocking some of the enzymes needed for cell growth. Lenalidomide may
stimulate the immune system to attack cancer cells. Giving ixazomib citrate and lenalidomide
as maintenance therapy after transplant may prolong the length of time until the cancer


I. Evaluate the toxicity of the use of ixazomib (ixazomib citrate) and lenalidomide as
maintenance therapy after autologous transplant.


I. Evaluate the ability to deliver the planned therapy.

II. Assess initial response to therapy.

III. Evaluate the median time to disease progression.

IV. Assess overall survival.


Within 30-120 days after completion of autologous transplant, patients receive ixazomib
citrate orally (PO) on days 1, 8 and 15 every 28 days for 2 courses, followed by lenalidomide
PO once daily (QD) on days 1-28 for 2 courses. Treatment repeats, alternating after every 2
courses, for up to 24 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 3
months for 2 years.

Inclusion Criteria:

- Eastern Cooperative Oncology Group (ECOG) performance status and/or other performance
status 0, 1, or 2

- Any autologous patient who underwent high dose melphalan (>= 140 mg/m^2)
therapy/peripheral blood stem cell (PBSC) rescue for any stage of multiple myeloma and
did not participate in another clinical transplant trial whose primary endpoint is
also evaluating long-term, disease-free survival or survival; consenting for study
between 30 days to 120 days after transplant; earliest can start therapy is 30 days
post transplant after recovered from acute toxicity of autologous stem cell transplant

- Voluntary written consent must be given before performance of any study related
procedure not part of standard medical care, with the understanding that consent may
be withdrawn by the patient at any time without prejudice to future medical care

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

- 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)

- Absolute neutrophil count (ANC) >= 1,000/mm^3

- Platelet count (transfusion independent) >= 75,000/mm^3

screening period

- Failure to have fully recovered (i.e., =< grade 1 toxicity) from the reversible
effects of prior ASCT chemotherapy

- Major surgery within 14 days before enrollment

- 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

3, subfamily A gene locus (CYP3A) (clarithromycin, telithromycin, itraconazole,

potentially interfere with the completion of treatment according to this protocol

- Known allergy to any of the study medications, their analogues, or excipients in the
various formulations of any agent; patient cannot be allergic to boron

previously diagnosed with another malignancy and have any evidence of residual
disease; patients with nonmelanoma skin cancer or carcinoma in situ of any type are
not excluded if they have undergone complete resection

examination during the screening period
