I. To estimate the response rate and to evaluate the antitumor activity of the three-drug combination, leflunomide, pomalidomide, and dexamethasone, in patients with relapsed/refractory multiple myeloma.
I. To characterize and evaluate toxicities, including type, frequency, severity, attribution, time course, and duration.
II. To obtain estimates of response duration, depth of response, clinical benefit, and survival (overall and progression-free).
Patients receive leflunomide orally (PO) on days 1-28, pomalidomide PO on days 1-21, and dexamethasone PO on days 1, 8, 15, and 22. Cycles repeat every 28 days 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 thereafter.

Experimental: Treatment (leflunomide, pomalidomide, dexamethasone)
Patients receive leflunomide PO on days 1-28, pomalidomide PO on days 1-21, and dexamethasone PO on days 1, 8, 15, and 22. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
- Overall response [ Time Frame: Up to 1 year ]Clopper Pearson binomial 95% confidence intervals will be calculated.
- Incidence of adverse events [ Time Frame: Up to 30 days after last dose ]Graded according to Common Terminology Criteria for Adverse Events (CTCAE) version (v)5. Observed toxicities will be summarized, for all dose levels, in terms of type (organ affected or laboratory determination), severity, time of onset, duration, probable association with the study treatment and reversibility or outcome.
- Response duration [ Time Frame: Up to 1 year ]Will be estimated using the product-limit method of Kaplan and Meier.
- Depth of response [ Time Frame: Up to 1 year ]Will be estimated using the product-limit method of Kaplan and Meier.
- Clinical benefit response [ Time Frame: Up to 1 year ]Clopper Pearson binomial 95% confidence intervals will be calculated.
- Overall survival [ Time Frame: Up to 1 year ]Will be estimated using the product-limit method of Kaplan and Meier.
- Minimal residual disease (MRD) status [ Time Frame: Up to 1 year ]A patient will be considered as having minimal residual diseases if a positive result is obtained using the Adaptive MRD testing. MRD testing will be performed at Adaptive Biotechnologies.
