Trial Description


This randomized phase II trial compares how well two different doses of carfilzomib work when given with dexamethasone in treating patients with multiple myeloma that has come back after a period of improvement or has not responded to treatment. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving carfilzomib together with dexamethasone may kill more cancer cells. It is not yet known whether a higher or lower dose of carfilzomib works better when given with dexamethasone.

Further Study Information


I. To evaluate and compare progression free survival (PFS) of two different doses of carfilzomib with dexamethasone in multiple myeloma (MM) patients with relapsed and/or refractory disease.


I. To evaluate and compare response rates (RR) for each arm.

II. To evaluate response rates (RR) for patients that relapse on low dose carfilzomib and subsequently cross-over to high dose carfilzomib.

III. To evaluate the safety of this combination for this patient population.

IV. To evaluate overall survival (OS).


I. To explore the molecular variability in MM cells obtained from extramedullary bone marrow relapse sites.

II. To explore the role of positron emission tomography (PET) scanning in assessing disease burden and as a tool to assess treatment response.

III. To explore changes in left ventricular ejection fraction (LVEF) in patients with relapsed or refractory multiple myeloma treated with low dose carfilzomib or high dose carfilzomib plus dexamethasone.

IV. To evaluate whether there is a difference in the incidence of clinically relevant cardiovascular toxicity between treatment arms (normal- versus high-dose carfilzomib).

V. To assess the timing and onset of clinically significant cardiotoxicity.

VI. To assess the relationship between patient characteristics, including demographic data, comorbid conditions, clinical data, echocardiography, and serum biomarkers and the development of clinically significant cardiotoxicity.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive dexamethasone intravenously (IV) and low-dose carfilzomib IV over 2-10 minutes on days 1, 2, 8, 9, 15, and 16. Patients with progression cross-over to Arm II.

ARM II: Patients receive dexamethasone IV and high-dose carfilzomib IV over 30 minutes on days 1, 2, 8, 9, 15, and 16.

Note that for the first course of treatment on both arms carfilzomib is given at a reduced rate to assess toxicity.

In both arms, treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 3 years from initial registration.

Eligibility Criteria

Inclusion Criteria:


Patients must have a confirmed diagnosis of symptomatic multiple myeloma and must be currently relapsed or refractory; except where otherwise indicated below that assessment is required within 14 days, all tests for establishing disease status must be completed within 28 days prior to registration and documented on the Baseline Tumor Assessment Form for Multiple Myeloma

Patients must have measurable disease within 28 days prior to registration; patients must have serum protein electrophoresis (SPEP) and urine protein electrophoresis (UPEP) within 14 days prior to registration

Patients must have received at least one prior regimen of chemotherapy for symptomatic multiple myeloma; patients may not have more than six (6) previous regimens of therapy for the disease; prior chemotherapy must have been completed at least 21 days prior to registration; for study purposes, a regimen is defined as follows:

An anti-myeloma therapy used at the time of initial diagnosis or documented disease progression which is given with the intent to decrease disease burden

Any maintenance therapy used after an Induction should be considered part of that Induction regimen

Use of any agent or combination of agents more than once during the patient’s disease history for separate documented disease progressions will be counted as separate regimens (e.g., if a patient receives lenalidomide/bortezomib at initial diagnosis and achieves response, but then progresses and receives lenalidomide/bortezomib after progression, these count as 2 separate regimens)

In cases of allogeneic or autologous stem cell transplant, the entire induction + stem cell mobilization + conditioning + planned maintenance should be considered one regimen

Patients may not have received any prior carfilzomib treatment

Patients must not be receiving any other concurrent therapy considered to be investigational; patients must not be planning to receive any radiotherapy (except localized radiation for palliative care); patients must not be planning to receive any concurrent chemotherapy, immunotherapy, radiotherapy or other treatment with curative intent

Patients must have complete history and physical examination within 28 days prior to registration

Patients must have baseline PET scan within 28 days prior to registration; note that images are submitted centrally for review

Patients with non-secretory MM or known primary amyloidosis are not eligible

Patients must have Zubrod performance status 0-2

Patients must not have clinically significant illness including uncontrolled, active infection requiring intravenous antibiotics, New York Heart Association (NYHA) class III or class IV heart failure, unstable angina pectoris, myocardial infarction within the past 6 months, or >= grade 3 cardiac arrhythmias

Patients must have undergone an electrocardiogram (EKG) within 28 days prior to registration

Patients must have either echocardiogram (ECHO) with ejection fraction >= 45% within 28 days prior to registration

Patients must not have > grade 2 neuropathy and/or POEMS syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes)

Total bilirubin =< 1.5 x upper limit of normal (ULN)

Serum glutamic oxaloacetic transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) =< 3 x ULN

Absolute neutrophil count (ANC) >= 1,000 cell/mm^3 without growth factor support within 14 days prior to registration

Platelets >= 50,000 cells/mm^3 for patients who have bone marrow plasmacytosis < 50% or >= 30,000 cells/mm^3 for patients who have bone marrow plasmacytosis of >= 50% within 14 days prior to registration

Calculated or measured creatinine clearance >= 30 ml/min within 14 days prior to registration

Patients who are known to be human immunodeficiency virus positive (HIV+) are eligible providing they meet all of the following additional criteria within 28 days prior to registration:

Cluster of differentiation (CD)4 cells >= 500/mm^3

Viral load of < 50 copies HIV messenger ribonucleic acid (mRNA)/mm^3 if on combination antiretroviral therapy (cART) or < 25,000 copies HIV mRNA if not on cART

No zidovudine or stavudine as part of cART

Patients who are HIV+ and do not meet all of these criteria are not eligible for this study

Patients with known hepatitis B or hepatitis C infection must have viral load < 800,000 IU/L within 28 days prior to registration
