What was measured
MRD is the small number myeloma cells surviving in the bone marrow after a clinical response has been measured and the patient is in remission. MRD negativity will be determined by deep sequencing of genomic deoxyribonucleic acid from bone marrow samples using rearranged Ig locus-specific primers (Adaptive, Seattle, WA). The MRD rate is the percentage of patients who are MRD negative at 10\^(-5), meaning that no MRD was detected in a sample of 100,000 cells. MRD status was assessed after 4 cycles of Isatuximab, Carfilzomib, Lenalidomide, and Dexamethasone (KRDI) induction, stem cell collection, and 4 additional cycles of KRDI (8 cycles total).
Analysis population: Of all patients enrolled to the main arm of the protocol (induction), 47 were evaluable for response. Of these 47 patients, 42 deferred stem cell transplant. 35 of these 42 patients had evaluable MRD results.
Groups in this outcome
Deferred Stem Cell Transplant (4 Cycles, Stem Cell Collection, 4 Additional Cycles)
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).
