No
- Capable of giving signed informed consent.
- Male or female, 18 years or older.
- Active plasma cell leukemia, symptomatic amyloidosis or active polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma proliferative disorder, and skin changes (POEMS) syndrome at the time of screening.

Inclusion and exclusion criteria
Inclusion criteria:
- Capable of giving signed informed consent.
- Male or female, 18 years or older.
- Have a confirmed diagnosis of multiple myeloma (MM) as defined by the International Myeloma Working Group (IMWG) criteria.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.
- Have been previously treated with at least 1 prior line of MM therapy including a lenalidomide-containing regimen and must have documented disease progression during or after their most recent therapy. (Participants treated with lenalidomide ≥10 mg daily for at least 2 consecutive cycles are eligible).
- Must have at least 1 aspect of measurable disease defined as one of the following; 1. Urine M-protein excretion greater than or equal to (≥)200 milligrams (mg) per 24-hour, or 2. Serum M-protein concentration ≥0.5 grams/deciliters (g/dL) (≥5.0 g/liter [L]), or 3.
