- Subjects may receive red blood cell (RBC) or platelet transfusions or receive supportive care such as erythropoietin and darbepoetin in accordance with institutional guidelines
-
Calculated and measured creatinine clearance of ≥ 30 mL/minute, calculated using the formula of Cockcroft and Gault [(140 - Age) X Mass (kg) / (72 X Creatinine mg/dL)]. Multiply result by 0.85 if female.
-
-
Ethical / Other
- Written informed consent in accordance with federal, local, and institutional guidelines
- Female subjects of child-bearing potential must have a negative serum pregnancy test within seven days of the first dose and agree to use dual methods of contraception during and for 3 months following last dose of drug. Post menopausal females (> 45 years old and without menses for > 1 year) and surgically sterilized females are exempt from a pregnancy test. Male subjects must use an effective barrier method of contraception during study and for 3 months following the last dose if sexually active with a female of child-bearing potential.

- Primary Outcome Measures
Name Time Method Best Overall Response Rate (ORR) A0: Subjects evaluated for disease response on Day 24 of Cycles 2, 4, 6, 9, and 12. Onset of response measured on Day 15 of Cycle 1. A1: Subjects evaluated for disease response on Day 15 of Cycle 1, Day 1 of Cycles 2 through 12 and at End of Study. For both A0 and A1, to evaluate the best overall response rate (stringent complete response \[sCR\]+ complete response \[CR\]+ very good partial response \[VGPR\]+ partial response \[PR\]) in patients with multiple myeloma who had previously received bortezomib and either thalidomide or lenalidomide, had relapsed after two or more therapies, and were refractory to the most recently received therapy
- Secondary Outcome Measures
Name Time Method Clinical Benefit Response (CBR) (A0 Only) Response assessments same as described in primary outcome measure sCR, CR, VGPR, PR, and minimal response (MR)
Clinical Benefit Response (CBR) (A1 Only) Response assessments same as described in primary outcome measure sCR, CR, VGPR, PR, and minimal response (MR)
Duration of Response (A0 Only) Response assessments same as described in primary outcome measure Duration of response (DOR) was calculated separately for subjects with clinical benefit response or overall response. DOR is defined as the time from first evidence of PR or better (for overall response) and MR or better (for clinical benefit response) to start of disease progression or death.
Duration of Response (A1 Only) Response assessments same as described in primary outcome measure Duration of response (DOR) was calculated separately for subjects with clinical benefit response or overall response. DOR is defined as the time from first evidence of PR or better (for overall response) and MR or better (for clinical benefit response) to start of disease progression or death.
Time to Progression (A0 Only) Response assessments same as described in primary outcome measure Time to progression (TTP) is defined as the time from the study entry (first dose of carfilzomib) to disease progression.
Time to Progression (A1 Only) Response assessments same as described in primary outcome measure Time to progression (TTP) is defined as the time from the study entry (first dose of carfilzomib) to disease progression.
Progression-free Survival (A0 Only) Response assessments same as described in primary outcome measure The PFS was defined as the time from the start of treatment to progressive disease (PD) determined by PI or until death.
Progression-free Survival (A1 Only) Response assessments same as described in primary outcome measure The PFS was defined as the time from the start of treatment to progressive disease (PD) determined by PI or until death.
Overall Survival (A1 Only) Patients were to be followed by telephone contact for disease progression and OS every 3 months after study discontinuation for the first year and every 6 months thereafter for up to 2 years The time from start of treatment to death due to any cause OS was to be censored on the date the subject was last known to be alive for those who were alive or lost to follow-up as of a data analysis cutoff date.
