Study of Initial Treatment With Elotuzumab, Carfilzomib, Lenalidomide and Dexamethasone in Multiple Myeloma

Open-label, Single-arm, Phase 2 Study of Initial Treatment With Elotuzumab, Carfilzomib (Kyprolis), Lenalidomide (Revlimid) and Low Dose Dexamethasone (E-KRd) in Newly Diagnosed, Multiple Myeloma Requiring Systemic Chemotherapy

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).

Study Overview

• Status: Completed
• Conditions: Multiple Myeloma
• Intervention / Treatment: Drug: Elotuzumab; Drug: Carfilzomib; Drug: Lenalidomide; Drug: Dexamethasone

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.

Intervention / Treatment

Experimental: 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.

Duration of Response	These events will be analyzed at differing points of time based on the individual subjects disease progression. It will be measured by the number of cycles of therapy.	Up to two years
Median Progression Free Survival	Progression free survival (PFS) was assessed based on time to disease progression or death (whichever occurred first) from the start of treatment.	up to two years
Median Overall Survival	Overall survival (OS) was assessed based on time to disease progression or death (whichever occurred first) from the start of treatment.	up to two years
