response [≥ partial response (PR)] to lenalidomide or bortezomib, subjects must have
relapsed within 6 months after stopping treatment with lenalidomide and/or

study treatment: 1) Plasmapheresis, 2) Major surgery, 3) Radiation therapy, 4) Use of
any anti-myeloma drug therapy

- Use of any investigational agents within 28 days or 5 half-lives (whichever is
longer) of treatment
