This is a Phase 3, randomized, open-label, multicenter study comparing two treatment regimens for subjects with multiple myeloma who have received all available approved treatment options and would otherwise be offered palliative care. These subjects must have received at least 3 prior treatments for their disease and be refractory to their most recent therapy.

Primary Outcome Measures:
  • Overall Survival [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    The primary objective of this study is to compare overall survival (OS) in patients with refractory multiple myeloma relapsed after at least 3 prior regimens who are randomized to receive either carfilzomib (Regimen C) or best supportive care (Regimen BSC).

Secondary Outcome Measures:
  • Progression Free Survival [ Time Frame: 1 year ] [ Designated as safety issue: No ]

    The secondary objectives of this study include investigating the effect of carfilzomib on other standard efficacy variables including PFS, overall response rate (ORR), disease control rate (DCR), and duration of response.

    Additionally, this study will examine the safety profile of carfilzomib alone compared with best supportive care based on the incidence and severity of adverse events (AEs) and laboratory changes.

Estimated Enrollment: 302

Arms Assigned Interventions

Corticosteroid (either prednisolone 30 mg orally (PO) every other day, dexamethasone 6 mg PO every other day, or other equivalent corticosteroid.

Optional cyclophosphamide 50 mg PO once daily may be given at the Investigator's discretion (maximum of 1400 mg per 28-day cycle).
