No
Key exclusion criteria

- Patient participated in any other clinical study within 1 month prior to enrollment in
this clinical study.

Summary
Brief summary
The primary purpose of this study is to identify the recommended Phase 2 dose(s) (RP2Ds) and
schedule assessed to be safe for EMB-06 and to characterize the safety and tolerability of
EMB-06 at the RP2Ds. Pharmacokinetics (PK), immunogenicity, and the anti-multiple myeloma
activity of EMB-06 will also be assessed.
