Brief summary
This study was a multi-center, open-label, single-arm, Phase 2 study where newly diagnosed Multiple Myeloma requiring systemic chemotherapy will be eligible for enrollment. A total of 46 subjects were enrolled. The primary end point was the rate of stringent complete response (sCR) and/or MRD-negativity (10-5) after C8 Elo-KRd. Secondary end points included safety, rate of response, MRD status, PFS, and overall survival (OS).
Detailed description
Primary Objective • The primary efficacy endpoint will be the rate of sCR and/or the rate of negative MRD by next generation gene sequencing (NGS) by clonoSIGHT (Adaptive Biotechnologies) at the end of 8 cycles among non-transplant candidates and transplant candidates who agreed to defer transplant Secondary Objectives * To evaluate the safety and tolerability of elotuzumab in combination with KRd, when administered to subjects with newly diagnosed multiple myeloma. * To determine the rate of MRD by next generation gene sequencing (NGS) by clonoSIGHT (Adaptive Biotechnologies) and by multi-color flow cytometry (MFC) at the end of Cycle 4, 8,and 12 for all subjects, and end of C18 (for subjects who are MRD+ at the end of C8 but MRD- at the end of C12 only), 24 months after C1D1, and yearly after that. * To estimate time to event, including duration of response (DOR), progression-free survival (PFS), time to progression (TTP), and overall survival (OS). Exploratory Objectives * GEP, proteomics, and gene sequencing to evaluate the correlation between treatment outcome and pre-treatment subject profile. * Immunologic correlative studies including FcγRIIIa V genotype.

Intervention model description
All participants will receive E-KRd regimen (elotuzumab, carfilzomib, lenalidomide, and dexamethasone) for up to 12 Cycles. After Cycle 12, participants that are MRD negative will move to E-Rd (elotuzumab, carfilzomib, lenalidomide, and dexamethasone) maintenance regimen and continue until disease progression. Participants that are MRD positive will continue to receive E-KRd regimen for an additional 6 cycles followed by E-Rd maintenance regimen and continue until disease progression

| Elo-KRd Regimen Subjects will be tested for Minimal Residual Disease (MRD) by Next Generation Sequencing (NGS) and flow cytometry after cycles 8 and 12. A treatment decision was made after cycle 12 based on these results. There are three outcomes based on the IFM trial (Avet-Loiseau et al., 2015): 1) if the subject is MRD-negative by NGS after cycle 8 and 12, the subject went on E-Rd maintenance until disease progression. 2) If the subject is MRD-positive after cycle 8 but MRD-negative after cycle 12, 6 more cycles of E-KRd was given and at the end of 18 cycles, the subject went on E-Rd maintenance until disease progression. 3) Finally, if the subject is MRD-positive at both instances, 12 additional cycles of E-KRd was given and at the end of 24 cycles total, the subject went on E-Rd maintenance until disease progression.
