About this trial
This phase I study utilizes a 3+3 design with escalating cohorts of Carfilzomib at 20mg/m2, 27mg/m2, 36mg/m2, 45mg/m2, 56mg/m2, and 70mg/m2 to be administered concomitantly with Cyclophosphamide 2 gm/m2, Dexamethasone and Granulocyte colony-stimulating factor (G-CSF)
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Serum monoclonal protein ≥ 0.5 g/dL
≥200 mg of monoclonal protein in the urine on 24-hour electrophoresis
Serum immunoglobulin free light chain: involved FLC ≥ 10 mg/dL (≥ 100 mg/L) AND abnormal serum immunoglobulin kappa to lambda free light chain ratio
MRD positivity in peripheral blood by flow cytometry.
Disqualifiers
Subject has a history of allergic reactions to compounds containing captisol, or Carfilzomib
Subject has a NYHA Class III or IV heart disease and/or a history of active unstable angina, congestive heart disease, severe uncontrolled cardiac arrhythmia, electrocardiographic evidence of acute ischemia, active conduction system abnormalities or myocardial infarction within 6 months prior to enrollment. Prior to study entry, any ECG abnormality at Screening has to be documented by the investigator as not medically relevant.
