15. Corrected QT interval (QTc) > 470 milliseconds on a 12-lead ECG obtained during the screening period.

16. Tested positive for human immunodeficiency virus (HIV) antibody, hepatitis B virus surface antigen (HBs antigen), or hepatitis C virus (HCV) antibody during the screening period.

17. Hypersensitivity to MLN9708 (including excipients), boron, or boron-containing drugs.

18. Hypersensitivity to lenalidomide, or dexamethasone, or excipients contained in the formulation of each drug (MLN9708 with Rd cohort only).

19. Known gastrointestinal diseases (difficulty swallowing, inflamed gastroenteritis, and Crohn disease), or gastrointestinal procedure (endoscopic procedure is permitted), that could interfere with the oral absorption or tolerance of the study treatment.
