Abstract

BACKGROUND: Elotuzumab, an immunostimulatory monoclonal antibody targeting signaling lymphocytic activation molecule F7 (SLAMF7), showed activity in combination with lenalidomide and dexamethasone in a phase 1b-2 study in patients with relapsed or refractory multiple myeloma. METHODS: In this phase 3 study, we randomly assigned patients to receive either elotuzumab plus lenalidomide and dexamethasone (elotuzumab group) or lenalidomide and dexamethasone alone (control group). Coprimary end points were progression-free survival and the overall response rate. Final results for the coprimary end points are reported on the basis of a planned interim analysis of progression-free survival. RESULTS: Overall, 321 patients were assigned to the elotuzumab group and 325 to the control group. After a median follow-up of 24.5 months, the rate of progression-free survival at 1 year in the elotuzumab group was 68%, as compared with 57% in the control group; at 2 years, the rates were 41% and 27%, respectively. Median progression-free survival in the elotuzumab group was 19.4 months, versus 14.9 months in the control group (hazard ratio for progression or death in the elotuzumab group, 0.70; 95% confidence interval, 0.57 to 0.85; P<0.001). The overall response rate in the elotuzumab group was 79%, versus 66% in the control group (P<0.001). Common grade 3 or 4 adverse events in the two groups were lymphocytopenia, neutropenia, fatigue, and pneumonia. Infusion reactions occurred in 33 patients (10%) in the elotuzumab group and were grade 1 or 2 in 29 patients. CONCLUSIONS: Patients with relapsed or refractory multiple myeloma who received a combination of elotuzumab, lenalidomide, and dexamethasone had a significant relative reduction of 30% in the risk of disease progression or death.

  • Elotuzumab does not have single-agent activity but shows synergistic activity when combined with lenalidomide and dexamethasone (Rd).

    “Unlike daratumumab, elotuzumab does not have single-agent activity but shows synergistic activity when combined with Rd (Table 8).84”

    From Multiple myeloma: 2024 update on diagnosis, risk-stratification, and management (2024) · cites this paper as [84]

    The Efficacy section (page unavailable in our copy) reports higher response rates with elotuzumab plus lenalidomide and dexamethasone than with lenalidomide and dexamethasone alone. That supports a benefit from adding elotuzumab, but the paper does not assess elotuzumab alone or establish that the combination is synergistic; searches for monotherapy and synergy found no such passage.

  • Elotuzumab targets SLAMF7, while daratumumab and isatuximab target CD38.

    “Elotuzumab targets SLAMF7; daratumumab and isatuximab target CD38 respectively.84–87”
  • Daratumumab with lenalidomide and dexamethasone was associated with clinically manageable adverse events that were consistent with the known toxic effects of lenalidomide and dexamethasone and of daratumumab.

    “Daratumumab with lenalidomide and dexamethasone was associated with clinically manageable adverse events that were consistent with the known toxic effects of lenalidomide and dexamethasone 27,28,30,31 and of daratumumab.9,10”
  • Elotuzumab has been proposed to function at least partially through upregulation of IL-2 production by T cells and stimulation of natural killer cell-mediated antibody-dependent cellular cytotoxicity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
