What was measured

The primary endpoint of MRD(-) rate, or percentage of patients with MRD(-) remissions, will be estimated along with two-sided 95% confidence interval using Clopper-Pearson exact method. Simon's optimal two-stage design will be utilized in determining the rate of MRD(-) cases. MRD assessment will be done with ClonoSEQ to identify myeloma-specific sequences.

Groups in this outcome

KRdD Followed by Auto-HCT

Cycle 1-Dexamethasone 40mg orally days 1/8/15/22; Lenalidomide 25mg orally days 1-21; Carfilzomib 20mg/m2 days 8/9 then 36mg/m2 venous days 15/16; Daratumumab 16mg/kg venous days 1/8/15/22 (KRd-Dara). Cycle 2 the same except Carfilzomib 36mg/m2 venous days 1/2/8/9/15/16. Cycles 3,4 the same but no Daratumumab Days 8 and 22. Dosage adjusted for last tolerated dose (LTD). Following induction therapy, auto-HCT is done (consolidation 1), then up to two 4-cycle blocks of KRd-Dara consolidation (consolidations 2 and 3). Minimum residual disease (MRD) checked after each phase. Patients with confirmed MRD(-) at or after consolidation 1 will not undergo maintenance and will be actively monitored for resurgence of MRD or clinical relapse. After consolidation if MRD+ patients will undergo standard of care lenalidomide maintenance. KRdD followed by auto-HCT: Dosages of each drug will vary depending on therapy type and cycle number. KRdD therapy will be followed by autologous hematopoietic cell transplantation and KRdD consolidation.

KRdD Only

Cycle 1-Dexamethasone 40mg orally days 1/8/15/22; Lenalidomide 25mg orally days 1-21; Carfilzomib 20mg/m2 days 8/9 then @ 36mg/m2 venous days 15/16; Daratumumab 16mg/kg venous days 1/8/15/22. Cycle 2 the same except Carfilzomib 36mg/m2 venous days 1/2/8/9/15/16. Cycles 3,4 the same but no Daratumumab Day 22. Dosage adjusted for last tolerated dose (LTD). Following induction therapy, Following induction therapy, patients will receive up to three 4-cycle blocks of KRd-Dara consolidation (consolidations 1, 2 and 3). Minimum residual disease (MRD) checked after each phase. Patients with confirmed MRD(-) at or after consolidation 1 will not undergo maintenance and will be actively monitored for resurgence of MRD or clinical relapse. After consolidation if MRD+ patients will undergo standard of care lenalidomide maintenance. KRdD only: Dosages of each drug will vary depending on therapy type and cycle number. KRdD therapy will not be followed by autologous hematopoietic cell transplantation but will proceed with KRdD consolidation.
