  * Urine M-protein ≥200 mg/24 hours, OR
  * In the absence of measurable M-protein, serum immunoglobulin free light chain ≥10 mg/dL, and abnormal serum immunoglobulin kappa lambda free light chain ratio (\<0.26 or \>1.65).
* Patients must have received prior treatment with an immunomodulatory drug (IMiD) (for ≥2 cycles or ≥2 months of treatment) and a proteasome inhibitor (PI) (for ≥2 cycles or ≥2 months of treatment).
* Patients must have received at least 3 prior lines of therapy (Note: Induction therapy and stem cell transplant ± maintenance will be considered as one line).

* Prior exposure to any agent (approved or investigational) that blocks the programmed cell death-1 (PD-1)/PD-L1 pathway.
* Evidence of other immune related disease/conditions.
* History of non-infectious pneumonitis requiring steroids or current pneumonitis; history of the thoracic radiation.
