A Study of Elotuzumab With Pomalidomide, Bortezomib, and Dexamethasone in Relapsed Multiple Myeloma

This research study is a phase II clinical trial, the investigators are studying the safety
and response rate of the combinations of elotuzumab, pomalidomide, bortezomib, dexamethasone
(elo-PVD).

The FDA (the U.S. Food and Drug Administration) has approved each of those drugs elotuzumab,
pomalidomide, bortezomib, dexamethasone as a treatment option for Refractory or relapsed
multiple myeloma.

Pomalidomide is a drug that changes that enhances or suppresses your immune systems reaction
to a stimulus.This change may help the body destroy tumor cells. Bortezomib is an inhibitor
that targets how cells dispose of unneeded proteins. By blocking this process, bortezomib can
help destroy unwanted cells. Dexamethasone is a steroid, that helps prevent inflammation in a
wide variety of organs and acts against myeloma cells. Elotuzumab is a monoclonal antibody,
Elotuzumab targets a protein that is highly common on the surface of multiple myeloma cells
called SLAMF7.

The combination of the drugs may provide an unique approach for treating the disease.

Inclusion Criteria:

- All laboratory assessments should be performed within 21 days of initiation of
protocol therapy unless otherwise specified.

- Participant has given voluntary signed written informed consent before performance of
any study-related procedure that is not part of normal medical care, with the
understanding that consent may be withdrawn by the subject at any time without
prejudice to their future medical care.

serum free kappa light chain ratio

- Previously treated relapsed and refractory multiple myeloma

- Patients must have received at least one prior therapy with at least 2 cycles of
lenalidomide and at least 2 cycles of a proteasome inhibitor (either in separate
regimens or within the same regimen)

- Disease progression on or within 60 days of completion of last therapy.

- ANC ≥ 1000/μL. G-CSF is not permitted within 14 days of screening.

criteria.

and serum aspartate transaminase (ALT) and/or aspartate transaminase (AST) values < 3
× the upper limit of normal (ULN) of the local laboratory reference range. Patients
with elevated bilirubin due to Gilbert's syndrome may be permitted with PI approval.

- Must be able to take acetylsalicylic acid (ASA) daily as prophylactic anticoagulation.
Patients intolerant to ASA may use low molecular weight heparin or equivalent.
Warfarin will be allowed provided patient is full anticoagulated, with an INR of 2-3.

- All study participants must be registered into the mandatory POMALYST REMS program,
and be willing and able to comply with the requirements of the POMALYST REMS program.

- Able to swallow capsules whole (pomalidomide capsules cannot be crushed, dissolved or
broken).

Exclusion Criteria:

- Prior therapy with elotuzumab

- Participants who have had chemotherapy or radiotherapy within 2 weeks (6 weeks for
nitrosoureas or mitomycin C) prior to entering the study or those who have not
recovered from adverse events due to agents administered more than 2 weeks earlier.
Patients may have received dexamethasone within 2 weeks prior to entering study.

- Participants who are receiving any other investigational agents.

- Concomitant high dose corticosteroids except patients may be on chronic steroids
(maximum dose 10 mg/day prednisone equivalent) if they are being given for disorders
other than myeloma, e.g. adrenal insufficiency, rheumatoid arthritis, etc.

- Pregnant or lactating females

- Prior history of malignancies, other than MM, unless the patient has been free of the
disease for ≥ 3 years. Exceptions include the following:

this trial.

prior hepatitis C infection but who have received an antiviral treatment and show no
detectable viral RNA for 6 months are eligible.

- Peripheral neuropathy ≥ grade 2 despite supportive therapy.

dexamethasone (such as Stevens-Johnson syndrome). Rash to immunomodulatory drug that
can be medically managed is allowable.

treatment and who have not discontinued immunosuppressive treatment for at least four
weeks prior to initiation of study treatment and who are currently dependent on such
treatment. Patients may also not have active graft v. host disease.

gastrointestinal, respiratory, or inflammatory illness that could preclude study
participation, pose an undue medical hazard, or interfere with the interpretation of

participation in the study, pose an undue medical hazard, interfere with the conduct
of the study, or interfere with interpretation of the study results
