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).

(Subjects are permitted to enroll if they have vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, euthyroid with a history of Grave's disease (participants with suspected autoimmune thyroid disorders must be negative for thyroglobulin and thyroid peroxidase antibodies and thyroid stimulating Ig prior to the first dose of study drug), psoriasis not requiring systemic treatment, well controlled asthma and/or mild allergic rhinitis [seasonal allergies], or conditions not expected to recur in the absence of an external trigger);

- If cTnT or cTnI levels are >1 ULN at 24 hours, the subject may undergo a cardiac evaluation and be considered for treatment, following a discussion with the Principal Investigator.
This study will enroll 104 patients to one of three treatment arms. The study is open to patients relapsing with refractory Multiple Myeloma who have: - received 3 prior lines of therapy - exposed to each of these 3 drug classes: - IMiD - proteasome inhibitors, and - anti-CD38 monoclonal antibody - relapsed and refractory are defined using the IMWG criteria: - disease that is non-responsive while on salvage therapy or progresses within 60 days of last therapy in patients who have achieved minimal response or better at some point previously to then progressing in their disease course.
