The most common all-grade non-hematologic AEs with and without elotuzumab, respectively, were fatigue (48% vs 40%), diarrhea (48% vs 37%), pyrexia (38% vs 28%), constipation (36% vs 28%), cough (33% vs 19%), and muscle spasms (30% vs 27%).

Infections of any grade were seen in 83% of patients in the elotuzumab arm compared with 75% with lenalidomide and dexamethasone alone. Once adjusting for treatment exposure, the rates were similar between the two arms. Infusion reactions, which were mostly grade 1/2, occurred in 10% of patients in the elotuzumab arm.

"Updated safety and tolerability data are consistent with previous findings, confirming that there is minimal incremental toxicity associated with the addition of elotuzumab to lenalidomide/dexamethasone," said Richardson.

A number of clinical trials continue to assess elotuzumab for patients with multiple myeloma. The ELOQUENT-1 trial is looking at elotuzumab in combination with lenalidomide and dexamethasone in newly diagnosed patients. Additionally, in the relapsed/refractory setting, elotuzumab is being assessed in combination with pomalidomide and dexamethasone and with the PD-1 inhibitor nivolumab.

"There's some very exciting trials going forward combining elotuzumab with other immuno-oncology agents, such as nivolumab, in the future," concluded Richardson.
