Open-label, Single-arm, Phase 2 Study of Initial Treatment With Daratumumab (Darzalex), Carfilzomib (Kyprolis), Lenalidomide (Revlimid) and Low Dose Dexamethasone (DKRd) in Newly Diagnosed, Multiple Myeloma Requiring Systemic Chemotherapy
Open-label, Single-arm, Phase 2 Study of Initial Treatment With Daratumumab (Darzalex), Carfilzomib (Kyprolis), Lenalidomide (Revlimid) and Low Dose Dexamethasone (DKRd) in Newly Diagnosed, Multiple Myeloma Requiring Systemic Chemotherapy
The purpose of this study is to determine response rate after 8 cycles of D-KRd (daratumumab, carfilzomib, lenalidomide (Revlimid) and dexamethasone in patients with multiple myeloma.
Inclusion Criteria:
Newly diagnosed, previously untreated myeloma requiring systemic chemotherapy
• Prior treatment of hypercalcemia or spinal cord compression or active and/or aggressively progressing myeloma with corticosteroids or lenalidomide or bortezomib-based regimens does not disqualify the patient (the treatment dose should not exceed the equivalent of 160 mg of dexamethasone in a 4 week period or not more than 1 cycle of Proteasome Inhibitor / Immunomodulatory-based therapy)
Both transplant and non-transplant candidates are eligible.
Diagnosis of symptomatic multiple myeloma as per current International Myeloma Working Group (IMWG) uniform criteria prior to initial treatment
Monoclonal plasma cells in the Bone Marrow (BM) ≥ 10% or presence of a biopsy-proven plasmacytoma
Measurable disease, prior to initial treatment as indicated by one or more of the following:
Bone marrow specimen will be required at study entry; available DNA sample from pre-induction BM will be used for calibration step for MRD evaluation by gene sequencing.
Males and females ≥ 18 years of age
Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
Adequate hepatic function, with bilirubin ≤ 1.5 x upper limit of normal (ULN) and aspirate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 x ULN
Absolute Neutrophil Count (ANC) ≥ 1.0 x 109/L, hemoglobin ≥ 8 g/dL, platelet count ≥ 75 x 109/L.
Calculated creatinine clearance (by Cockroft-Gault) ≥ 50 mL/min or serum creatinine below 2 g/dL
Woman of childbearing potential must have 2 negative pregnancy tests prior to initiating lenalidomide.
Woman of childbearing potential must agree to use 2 reliable forms of contraception simultaneously or to practice complete abstinence from heterosexual intercourse during the following time periods related to this study: 1) for at least 28 days before starting lenalidomide; 2) while participating in the study; and 3) for at least 30 days after discontinuation from the study.
Male subjects must agree to use a latex condom during sexual contact with females of childbearing potential while participating in the study and for at least 90 days following discontinuation from the study even if he has undergone a successful vasectomy.
All study participants in the US must be consented to and registered into the mandatory Revlimid Risk Evaluation and Mitigation Strategy (REMS®) program and be willing and able to comply with the requirements of Revlimid REMS®.
Voluntary written informed consent.
Exclusion Criteria:
Frail non-transplant candidates, defined as in Palumbo et al, Blood 2015.

Amyloidosis
Plasma cell leukemia
Waldenström's macroglobulinemia or Immunoglobulin M-producing (IgM) myeloma
