"refractory myeloma" nor "relapsed-and-refractory myeloma"
- Refractory myeloma: Nonresponsive myeloma while on primary or salvage therapy, or
progresses within 60 days of last therapy. Nonresponsive disease is defined as
failure to achieve minimal response (MR) or better, achieved with any therapy.

clinical progression, are included, as well those cases that progress in disease
course

salvage therapy or progresses with 60 days of last therapy after achieving
MR or better previously before progressing

pomalidomide, or thalidomide) is permitted. The washout period is 2 weeks (14
days) prior to start of study treatment (C1D1)

except if due to Gilbert's syndrome, or other documented historical
elevations in serum bilirubin levels, at the discretion of the investigator,

[SGOT])/alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase
[SGPT]) =< 2 x IULN
- Must have adequate renal function, as defined by:
- Creatinine clearance (CrCl) of >= 30 mL/min, as measured by a 24-hour urine
collection or as estimated by the Cockcroft and Gault formula. The serum
creatinine value used in the calculation must have been obtained within 35
days prior to registration.
- For patients with a creatinine clearance within the range of 30-45 mL/min,
stability (i.e., not deteriorating) must be demonstrated over a period of 8
weeks prior to enrollment in the study
- Lab parameters must continue to be met at the time of registration. If parameters
not met at the intended C1D1, transfusion or growth factor support may be
considered in consultation with the team, if the individual is still within the
screening window
- Left ventricular ejection fraction (LVEF) by echocardiogram >= 40%. The echocardiogram
study should be obtained during screening or up to 60 days prior to consent
- Women of childbearing potential must have a negative serum or urine pregnancy test
within 14 days prior to receiving the first dose of study medication. If the urine
pregnancy test is positive or cannot be confirmed as negative, a serum pregnancy test
will be required
- Female participants of childbearing potential (FOCBP) must agree to use
highly-effective method(s) of contraception during the study and for 3 months after
the last dose of study drug. FOCBP are those who have not been surgically sterilized
or have not been free from menses for > 1 year without an alternative medical cause

real-time polymerase chain reaction (PCR) measurement of hepatitis B virus
deoxyribonucleic acid (DNA) levels. Those who are PCR positive will be excluded.
