  • Outcome Measures

    Primary Outcome Measures

    1. Best Overall Response Rate (ORR) in the Response Evaluable Subset Population [Disease response was assessed on Day 15 of Cycle 1, Day 1 of Cycles 2 through 12, and at End of Study, 30 days after last dose. Median duration of treatment was 100 days for Part 1 and 170 days for Part 2 participants.]

      ORR is defined as the percentage of patients who achieved a best response of stringent complete response (sCR), complete response (CR), very good partial response (VGPR) or partial response (PR) determined by Independent Review Committee (IRC). Responses were assessed according to International Uniform Response Criteria for Multiple Myeloma, documented by 2 consecutive assessments made at any time before the start of new therapy. sCR: CR as defined below plus normal FLC ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence. CR: absence of M-protein in serum and urine by immunofixation, disappearance of any soft tissue plasmacytomas, and ≤5% plasma cells in bone marrow. VGPR: serum and urine M-proteins detectable by immunofixation but not by electrophoresis or a ≥ 90% reduction in serum M-protein with urine M-protein level < 100 mg/24 hours. PR: ≥ 50% reduction of serum M-protein and in urine of ≥ 90% or to < 200 mg per 24 hours.

    Secondary Outcome Measures

    1. Best Overall Response Rate (ORR) in the Response Evaluable Population [Disease response was assessed on Day 15 of Cycle 1, Day 1 of Cycles 2 through 12, End of Study, 30 days after last dose; median duration of treatment was 100 days for Part 1 and 170 days for Part 2 participants.]

      ORR is defined as the percentage of patients who achieved a best response of stringent complete response (sCR), complete response (CR), very good partial response (VGPR) or partial response (PR) determined by Independent Review Committee (IRC).

CR: absence of M-protein in serum and urine by immunofixation, disappearance of any soft tissue plasmacytomas, and ≤5% plasma cells in bone marrow. VGPR: serum and urine M-proteins detectable by immunofixation but not by electrophoresis or a ≥ 90% reduction in serum M-protein with urine M-protein level < 100 mg/24 hours. PR: ≥ 50% reduction of serum M-protein and in urine of ≥ 90% or to < 200 mg per 24 hours.

    2. Clinical Benefit Rate (CBR) [Disease response was assessed on Day 15 of Cycle 1, Day 1 of Cycles 2 through 12, and at End of Study, 30 days after last dose. Median duration of treatment was 100 days for Part 1 and 170 days for Part 2 participants.]

      Clinical Benefit Rate is defined as the percentage of participants with a best overall response of minimal response (MR) or better, i.e., a best overall response of sCR, CR, VGPR, PR, or MR. MR was defined as outlined by European Group for Blood and Marrow Transplantation (EBMT) criteria, defined as reduction of M-protein in serum of 25% to 49% and in urine of 50% to 89%, maintained for 6 weeks.

    3. Duration of Response (DOR) [Patients were followed for up to 2 years after study discontinuation. The data cutoff for the analysis is 30 November 2010 for Part 1 and 22 April 2011 for Part 2.]

      DOR is defined as the time from first evidence of PR or better to disease progression assessed by the IRC or death due to any cause. Patients lost to follow-up prior to disease progression or who were alive without disease progression before the analysis cutoff date were censored at the last disease assessment. Progressive disease was defined as any of the following: An increase of M-protein in serum (absolute increase ≥ 0.5 g/dL) or urine (absolute increase ≥ 200 mg/24 hours) of > 25% from the nadir (if not zero). Percentage of plasma cells in bone marrow ≥ 10%. New or increased size of bone lesions or new plasmacytomas. Patients without measurable serum and urine M-protein: 25% increase from nadir in the difference between involved and uninvolved FLC levels and absolute increase >10 mg/dL. Development of hypercalcemia (corrected serum calcium > 11.5 mg/dL) attributed solely to the proliferative disorder. Median DOR was estimated using Kaplan-Meier methods.

    4. Time to Progression (TTP) [Patients were followed for up to 2 years after study discontinuation. The data cutoff for the analysis is 30 November 2010 for Part 1 and 22 April 2011 for Part 2. Median follow-up time was 13.4 months for Part 1 and 11.5 months in Part 2.]

      Time to Progression is defined as the time from the start of treatment to IRC-determined disease progression. Patients who were lost to follow-up prior to documentation of disease progression, or who died before documentation of disease progression or who were alive and did not have documentation of disease progression before the data analysis cut-off date were censored at the last disease assessment. Median TTP was estimated using the Kaplan-Meier method.

    5. Progression-free Survival (PFS) [Patients were followed for up to 2 years after study discontinuation. The data cutoff for the analysis is 30 November 2010 for Part 1 and 22 April 2011 for Part 2. Median follow-up time was 13.4 months for Part 1 and 11.5 months in Part 2.]

      Progression-free Survival (PFS) is defined as the time from start of treatment to IRC determined disease progression or death due to any cause. Patients who were lost to follow-up prior to documentation of disease progression and patients who were alive without disease progression before a data analysis cut-off date were censored at the last disease assessment. Median PFS was estimated using the Kaplan-Meier method.

    6. Overall Survival (OS) [Patients were followed for up to 2 years after study discontinuation. The data cutoff for the analysis is 19 November 2012 for Part 1 and 07 January 2013 for Part 2. Median follow-up time was 19.1 months for Part 1 and 35.9 months in Part 2.]

      Overall Survival is defined as the time from the start of study treatment to date of death due to any cause. Patients who were alive or lost to follow-up as of the data analysis cut-off date for the final OS analysis were censored at the date the patient was last known to be alive. Median OS was estimated using the Kaplan-Meier method.

    Study Results

    Participant Flow

    Recruitment Details This study enrolled patients with multiple myeloma (MM) who had relapsed or refractory disease after at least 1 but no more than 3 prior therapeutic treatments or regimens. The first patient enrolled on 24 September 2007; the last patient was enrolled and received carfilzomib on 28 May 2009.
    Pre-assignment Detail Two groups of patients with MM were initially studied: bortezomib-treated (Part 1) and bortezomib-naïve (Part 2). Following Amendment 2, only bortezomib-naïve patients were enrolled. With Amendment 3, a new cohort of "stepped up" dosing was added to the trial. Study results were analyzed in 2 parts, based on previous bortezomib treatment.
    Arm/Group Title Part 1: Carfilzomib 20 mg/m² Part 2: Carfilzomib 20 mg/m² Part 2: Carfilzomib 20/27 mg/m²
    Arm/Group Description Participants previously treated with bortezomib received carfilzomib 20 mg/m² intravenous (IV) injection on Days 1, 2, 8, 9, 15, and 16, in 28-day treatment cycles for a maximum of 12 cycles. Participants not previously treated with bortezomib received carfilzomib 20 mg/m² IV injection on Days 1, 2, 8, 9, 15, and 16, in 28-day treatment cycles for a maximum of 12 cycles. Participants not previously treated with bortezomib received carfilzomib 20 mg/m² IV on Days 1, 2, 8, 9, 15, and 16 of Cycle 1. If all doses were well-tolerated the dose was escalated to 27 mg/m² IV on Days 1, 2, 8, 9, 15, and 16 of subsequent cycles, for up to 12 cycles.

    Description ORR is defined as the percentage of patients who achieved a best response of stringent complete response (sCR), complete response (CR), very good partial response (VGPR) or partial response (PR) determined by Independent Review Committee (IRC). Responses were assessed according to International Uniform Response Criteria for Multiple Myeloma, documented by 2 consecutive assessments made at any time before the start of new therapy. sCR: CR as defined below plus normal FLC ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence. CR: absence of M-protein in serum and urine by immunofixation, disappearance of any soft tissue plasmacytomas, and ≤5% plasma cells in bone marrow. VGPR: serum and urine M-proteins detectable by immunofixation but not by electrophoresis or a ≥ 90% reduction in serum M-protein with urine M-protein level < 100 mg/24 hours. PR: ≥ 50% reduction of serum M-protein and in urine of ≥ 90% or to < 200 mg per 24 hours.
    Time Frame Disease response was assessed on Day 15 of Cycle 1, Day 1 of Cycles 2 through 12, and at End of Study, 30 days after last dose. Median duration of treatment was 100 days for Part 1 and 170 days for Part 2 participants.

    Title Duration of Response (DOR)
    Description DOR is defined as the time from first evidence of PR or better to disease progression assessed by the IRC or death due to any cause. Patients lost to follow-up prior to disease progression or who were alive without disease progression before the analysis cutoff date were censored at the last disease assessment. Progressive disease was defined as any of the following: An increase of M-protein in serum (absolute increase ≥ 0.5 g/dL) or urine (absolute increase ≥ 200 mg/24 hours) of > 25% from the nadir (if not zero). Percentage of plasma cells in bone marrow ≥ 10%. New or increased size of bone lesions or new plasmacytomas. Patients without measurable serum and urine M-protein: 25% increase from nadir in the difference between involved and uninvolved FLC levels and absolute increase >10 mg/dL. Development of hypercalcemia (corrected serum calcium > 11.5 mg/dL) attributed solely to the proliferative disorder. Median DOR was estimated using Kaplan-Meier methods.
    Time Frame Patients were followed for up to 2 years after study discontinuation. The data cutoff for the analysis is 30 November 2010 for Part 1 and 22 April 2011 for Part 2.
