CARAMEL 2: Carfilzomib and Dexamethasone in Treating Patients With Multiple Myeloma Who Previously Underwent a Stem Cell Transplant
Study Details
Study Description
Brief Summary
This phase II trial studies how well carfilzomib and dexamethasone work in treating patients with multiple myeloma who previously underwent a stem cell transplant. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Immunosuppressive therapy, such as dexamethasone, may improve bone marrow function and increase blood cell counts. Giving carfilzomib together with dexamethasone may be an effective treatment for multiple myeloma.

Phase 2 |
Detailed Description
PRIMARY OBJECTIVES:
- To assess the complete response (CR) rate with carfilzomib and dexamethasone consolidation following an upfront single stem cell transplant (SCT).
SECONDARY OBJECTIVES:
-
To assess the toxicity of carfilzomib and dexamethasone when used as consolidation therapy in patients post SCT.
-
To determine the progression free rate at 1 and 2 years post SCT. III. To evaluate progression-free survival and overall survival.
TERTIARY OBJECTIVES:
-
To determine the proportion of patients achieving a minimal residual disease (MRD) negative status.
-
To assess the HevyLite assay prior to and during treatment.
OUTLINE:
Patients receive carfilzomib intravenously (IV) over 30 minutes and dexamethasone orally (PO) on days 1, 2, 15, and 16. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study therapy, patients are followed up every 3 months for 3 years and then every 6 months for 2 years.

Outcome Measures
Primary Outcome Measures
- Rate of complete response [Up to 5 years]
The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Exact binomial 95% confidence intervals for the true success proportion will be calculated.
Secondary Outcome Measures
- Overall survival [Time from registration to death due to any cause, assessed up to 5 years]
The distribution of survival time will be estimated using the method of Kaplan-Meier.
- Progression-free survival [Time from registration to progression or death due to any cause, assessed up to 5 years]
The distribution of progression-free survival will be estimated using the method of Kaplan-Meier.
- Time to progression post SCT [Time from SCT to the earliest day with documentation of disease progression, assessed at 1 year post-SCT]
The distribution of time to progression will be estimated using the method of Kaplan-Meier.
- Time to progression post SCT [Time from SCT to the earliest day with documentation of disease progression, assessed at 2 years post-SCT]
The distribution of time to progression will be estimated using the method of Kaplan-Meier.
- Maximum grade for each type of adverse event [Up to 30 days after last day of treatment]
Frequency tables will be reviewed to determine adverse event patterns.

-
Negative pregnancy test performed =< 7 days prior to registration, for women of childbearing potential only
-
Willingness to return to one of the enrolling institutions for follow-up (during the active monitoring phase of the study); NOTE: during the active monitoring phase of a study (i.e., active treatment and observation), participants must be willing to return to the consenting institution for follow-up
-

= 200 mg of monoclonal protein in the urine on 24 hour electrophoresis
-
Serum immunoglobulin free light chain >= 10 mg/dL AND abnormal serum immunoglobulin kappa to lambda free light chain ratio
-
NOTE: for patients with no relapse prior to transplant, measurable disease at the time of diagnosis
-
NOTE: for patients who have had a disease relapse prior to transplant, measurable disease at the time of the most recent relapse immediately prior to transplant; NOTE: if the patient had treatment for the relapsed disease prior to transplant, the patient must have measurable disease at the time of relapse prior to this therapy

-
New York Heart Association (NYHA) class III or IV heart failure
-
Uncontrolled angina
-
Severe uncontrolled ventricular arrhythmias
-
Electrocardiographic (ECG) evidence of acute ischemia or active conduction system abnormalities; NOTE: prior to study entry, any ECG abnormality at screening has to be documented by the investigator as not medically relevant

-
Concurrent chemotherapy, radiotherapy, or any ancillary therapy considered investigational; NOTE: bisphosphonates are considered to be supportive care rather than therapy, and are thus allowed while on protocol treatment
-
Known allergies to any of the components of the investigational treatment regimen or required ancillary treatments
