What was measured

Percentage of patients who achieved a complete response (CR) or stringent CR (sCR) per International Myeloma Working Group (IMWG) Uniform Response criteria after 4 cycles of of Isatuximab, Carfilzomib, Lenalidomide, and Dexamethasone (KRDI). IMWG criteria define a CR as "Negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and \< 5% plasma cells in bone marrow" and an sCR as "CR plus normal FLC ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence."

Groups in this outcome

Induction

All participants will receive 4 cycles of induction therapy. Based on the recommendation of investigators, participants may or may not proceed to an autologous stem cell transplant (SCT) after cycles 1-4. Each cycle is 28 days in length (see dosing details below.) For patient undergoing upfront stem cell transplant (SCT): 4 cycles followed by stem cell collection, high-dose chemotherapy, and autologous SCT followed by 2 cycles (called consolidation). For patients deferring SCT following collection: 4 cycles followed by stem cell collection followed by 4 additional cycles. Carfilzomib: 56 mg/m2 IV on days 1, 8,15 Lenalidomide 25 mg orally (PO) on Days 1-21 Isatuximab: 10 mg/kg IV weekly for cycles 1-2 (days 1, 8, 15, 22), then every 2 weeks for cycles 3-6 (days 1 and 15), and monthly (day 1) thereafter Dexamethasone: 20 mg orally (PO) administered day of and day after carfilzomib and isatuximab (days 1, 2, 8, 9, 15, and 16; days 22 and 23 during cycles 1-2 only). Patients achieving a partial response (PR) or greater will be stratified by cytogenetic risk and receive either high risk (Lenalidomide 10 mg orally (PO) Day 1-21 Carfilzomib 56 mg/m2 or last tolerated dose IV Days 1, 15 Isatuximab 10 mg/kg IV Day 1) or low risk maintenance therapy (Lenalidomide 10 mg orally (PO) Day 1-21).
