Summary
This a Phase I/II randomized trial for patients with relapsed refractory Multiple Myeloma who have relapsed after treatment with prior therapies. The protocol is designed to evaluate two agents, Anti-LAG-3 and Anti-TIGIT, in order to understand their immunologic effects and safety both as single agents and in combination with pomalidomide and dexamethasone. In these arms, patients will be treated with either Anti-LAG-3 or Anti-TIGIT respectively for one cycle as single agent followed by the addition of pomalidomide and dexamethasone in combination for subsequent cycles. A third arm allows patients to be treated with the FDA approved combination of elotuzumab plus pomalidomide and dexamethsone as a control. This arm will thus allow a concurrent standard of care comparator for the experimental arms.

Criteria
Inclusion Criteria:

1. 18 years of age or greater.

therapy including at least one drug from each drug class; IMiD, proteasome inhibitors,
and anti-CD38 monoclonal antibody.

4. The following laboratory values obtained ≤ 14 days prior to initiation of therapy:

1. ANC ≥ 1000/ul (without growth factor support within 14 days of initiation of
therapy)

2. Hgb ≥ 8 g/dl

3. PLT ≥ 75,000/ul (without transfusion support within 14 days of initiation of
therapy)

4. Total bilirubin <1.5 x upper limit of normal (ULN) or if total bilirubin is ≥1.5
x ULN, the direct bilirubin must be ≤ 2.0 mg/dL (patients with Gilberts syndrome
may have total bilirubin ≤3.0 x ULN

5. AST and ALT < 2.5x ULN

6. Creatinine Clearance ≥ 30 mL/min by Cockcroft Gault Equation

5. Measurable disease of MM as defined by at least ONE of the following:

1. Serum monoclonal protein ≥1.0 g by protein electrophoresis

2. ≥200 mg of monoclonal protein in the urine on 24-hour electrophoresis

3. Serum immunoglobulin FLC ≥10 mg/dL AND abnormal serum immunoglobulin kappa to
lambda FLC ratio.

6. Normal thyroid function, or stable on hormone supplementation per investigator
assessment.

7. Eastern Cooperative Oncology Group (ECOG) Performance Status 0, 1, or 2.

8. Willingness to return to enrolling institution for follow-up.

9. Disease free of prior malignancies for ≥ 3 year with exception of currently treated
basal cell, squamous cell carcinoma of the skin, carcinoma "insitu" of the cervix or
breast, or prostate cancer not requiring therapy

10. Ability to understand the purpose and risks of the study and provide signed and dated
ICF and authorization to use protected health information.

11. All study participants must be willing to be registered into, and comply with, the
mandatory pomalidomide (POMALYST®) Risk Evaluation and Mitigation Strategy (REMS®)
program and be willing to use contraception 28 days prior to pomalidomide treatment
and continue until 120 days after the last dose of pomalidomide.

12. Able to take aspirin (81 or 325 mg) daily as prophylactic anticoagulation. For
patient's intolerant to aspirin or for high-risk patients with prior history of
thromboembolic events, thromboprophylaxis with other anti-coagulants agents, including
low molecular weight heparin, warfarin, or novel oral anticoagulants such as apixaban
or rivaroxaban, is allowed.

13. All females of child bearing potential (FCBP)* must have a negative pregnancy test
(urine or serum) documented ≤7 days prior to start of therapy with repeat pregnancy
test on Day 1 of each cycle and at the EoT visit. Note: Additional pregnancy testing
is required as a condition of the POMALYST REMS® program prior to and while on
treatment and following the last dose of pomalidomide. FCBP must have 2 negative
pregnancy tests prior to initiating pomalidomide treatment. The first test should be
performed within 10-14 days prior to prescribing POMALYST and the second test within
24 hours prior to prescribing POMALYST therapy and then weekly during the first 4
weeks, then every 4 weeks thereafter in females with regular menstrual cycles, or
every 2 weeks in females with irregular menstrual cycles. Protocol section 8.1
provides guidelines on the use and required time frames of contraception. NOTE: *A
female of childbearing potential (FCBP) is a sexually mature female who: 1) has not
undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally
postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in
the preceding 24 consecutive months).
