• Patients with relapsed/refractory multiple myeloma. Relapsed is defined as: Patients have disease progression after at least three-line treatment regimens. Patients previously received at least 3 different mechanisms treatment regimens for multiple myeloma, including protease inhibitors and immunomodulators; Refractory is defined as: Patients who achieved minimal response(MR) or above was never achieved in previous treatment; MR or above was achieved in previous treatment, but disease progression occurred during subsequent treatment or within 60 days after the last treatment.
