研究概览
简要总结
This phase II trial studies how well carfilzomib works in treating patients with multiple myeloma in first relapse or refractory to first-line therapy. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
详细描述
PRIMARY OBJECTIVES:
I. To assess the overall response rate of carfilzomib after 8 cycles of treatment in patients with first-relapsed myeloma.
SECONDARY OBJECTIVES:
I. To assess the overall response rate to single agent carfilzomib after 4 cycles of treatment.
II. To assess progression-free survival (PFS). III. To assess time to progression (TTP). IV. To assess duration of response (DOR). V. To assess toxicities.

入选标准
- •Multiple myeloma (MM) in first relapse or refractory to first line therapy; the previous line of therapy should include either an immunomodulatory agent or a proteasome inhibitor
- •Refractory disease is defined as =< 25% response or progression during therapy or within 60 days after completion
- •The number of prior lines of anti-myeloma therapy will be determined as follows:
- •Induction chemotherapy for peripheral-blood stem cell harvest followed by planned mobilization and subsequent high-dose chemotherapy with autologous stem cell transplant (ASCT) is considered one therapy regardless of the induction regimen
- •Planned maintenance therapy after stem cell transplantation or other induction therapy is not considered a separate line of therapy, as long as there is no evidence of progression in the time between the induction or transplantation and the initiation of maintenance therapy
- •Two ASCTs within 6 months of each other is considered as one line unless different agents were used in the high-dose therapy-conditioning regimens
- •If the same regimen is repeated after a 6-month interval, they are considered to be two separate therapeutic lines
- •If cyclophosphamide is used for reasons other than planned stem cell mobilization, its use is considered to be a separate line of therapy
- •Dose modification of steroid and altering choices of steroid (i.e. from dexamethasone to prednisone) due to side effects, is not considered a line of therapy, as long as there is no evidence of progression
- •If a regimen was stopped for more than 2 months, its re-initiation is counted as another line of therapy
- •Presence of existing lytic bone lesions either by skeletal X-ray, computed tomography (CT) scan or magnetic resonance imaging (MRI) scan

- •Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase (SGOT) and/or alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase (SGPT) =< 2.5 × the upper limit of normal (ULN)
- •Bilirubin < 2.0 mg/dL
- •Serum creatinine =< 3.0 mg/dL or a calculated creatinine clearance of at least 15 mL/min (using the Cockcroft and Gault method)
- •Adequate cardiac function defined as left ventricular ejection fraction (LVEF) >= 40%
- •NOTE: 2-dimensional (2-D) transthoracic echocardiogram (ECHO) is the preferred method of evaluation
- •Multigated acquisition scan (MUGA) is acceptable if ECHO is not available
- •Written informed consent in accordance with federal, local, and institutional guidelines

- •Male subjects must agree to practice contraception
排除标准

- •No autologous or allogeneic stem cell transplant within 3 months prior to cycle 1 day 1
- •No radiotherapy within 21 days prior to cycle 1 day 1; however, if the radiation portal covered =< 5% of the bone marrow reserve, the patient may be enrolled irrespective of the end date of radiotherapy
- •No major surgery within 14 days and minor surgery within 7 days prior to cycle 1 day 1
- •No pregnant or lactating females
- •No acute active infection requiring treatment (systemic antibiotics, antivirals, or antifungals) within 14 days prior to cycle 1 day 1
- •No known human immunodeficiency virus (HIV) infection
- •No active hepatitis B or C infection
- •No unstable angina or myocardial infarction within 4 months prior to cycle 1 day 1, New York Heart Association (NYHA) class III or IV heart failure, uncontrolled angina, history of severe coronary artery disease, severe uncontrolled ventricular arrhythmias, sick sinus syndrome, or electrocardiographic evidence of acute ischemia or grade 3 conduction system abnormalities unless subject has a pacemaker
- •No uncontrolled hypertension or uncontrolled diabetes (as determined by the treating physician) within 14 days prior to cycle 1 day 1
- •No nonhematologic malignancy within the past 3 years with the exception of a) adequately treated basal cell carcinoma, squamous cell skin cancer, or thyroid cancer; b) carcinoma in situ of the cervix or breast; c) prostate cancer of Gleason grade 6 or less with stable prostate-specific antigen levels; or d) cancer considered cured by surgical resection or unlikely to impact survival during the duration of the study, such as localized transitional cell carcinoma of the bladder or benign tumors of the adrenal or pancreas
