Elotuzumab is a humanized monoclonal antibody that targets the SLAMF7 (signaling lymphocytic activation molecule F7) receptor expressed on myeloma cells and natural killer (NK) cells. It enhances NK cell-mediated antibody-dependent cellular cytotoxicity (ADCC) via direct activation of NK cells through SLAMF7 and CD16 engagement, and also directly activates NK cells to induce killing of myeloma cells.
Disialoganglioside GD2-binding monoclonal antibody that induces antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity against GD2-positive tumor cells.

History of severe hypersensitivity reactions to elotuzumab or any of its excipients
None known.
No specific food interactions with Empliciti have been identified. However, when used in combination with lenalidomide and dexamethasone, patients should avoid grapefruit and grapefruit juice due to potential interaction with lenalidomide metabolism (CYP3A4). Maintain adequate hydration and nutrition as tolerated.
No specific food interactions are established for DANYELZA. Maintain adequate hydration and nutrition as tolerated. Avoid grapefruit and grapefruit juice if taking concomitant medications that are CYP3A4 substrates, though DANYELZA itself is not metabolized by CYP450 enzymes.
Pregnancy Category N (not classified). Empliciti (elotuzumab) is a monoclonal antibody. Ig G molecules cross the placenta, with increasing transfer in the second and third trimesters. Based on its mechanism of action (SLAMF7-directed immunostimulatory), there is potential for fetal harm including B-cell depletion and immune alterations. No adequate human data; animal studies have not been conducted. Avoid use during pregnancy unless benefit outweighs risk.
Based on its mechanism of action (GD2-directed antibody), DANYELZA may cause fetal harm. There are no adequate human data. In animal studies, administration resulted in embryofetal toxicity including malformations and growth retardation. Advise females of reproductive potential of the potential risk to a fetus. Use effective contraception during treatment and for at least 2 months after the last dose.
No data on presence in human milk, effects on breastfed infant, or milk production. Human Ig G is excreted in breast milk but not systemically absorbed in significant amounts. M/P ratio unknown. Consider developmental and health benefits of breastfeeding along with maternal need for therapy and potential adverse effects on infant (B-cell depletion).
No data on presence in human milk, effects on breastfed infant, or effects on milk production. Because of the potential for serious adverse reactions, advise women not to breastfeed during treatment and for at least 2 months after the last dose.
No pharmacokinetic data in pregnancy. Monoclonal antibodies may have altered clearance due to increased plasma volume. However, no recommended dose adjustment; use with caution. No specific guidelines for dose modification during pregnancy.
Dosing adjustments during pregnancy are not established. Use only if potential benefit justifies potential risk to the fetus. Consider delaying treatment until after delivery if feasible.
Empliciti (elotuzumab) is an immunostimulatory monoclonal antibody used in combination with lenalidomide and dexamethasone for relapsed/refractory multiple myeloma. Premedicate with diphenhydramine, acetaminophen, and H2 blocker to mitigate infusion reactions (IRs). Monitor for IRs, notably hypotension, bronchospasm, and urticaria, especially during the first dose. Administer corticosteroids prior to empliciti infusion to reduce IR risk. Do not administer as an intravenous push or bolus; use a controlled intravenous infusion. If a dose is missed, administer as soon as possible; do not wait until the next scheduled dose. Empliciti carries a boxed warning for increased mortality when used with lenalidomide and dexamethasone in patients with previously untreated multiple myeloma who are not candidates for transplant. Advise patients of potential teratogenicity with lenalidomide and dexamethasone; ensure pregnancy prevention.
DANYELZA (naxitamab) is a GD2-binding monoclonal antibody for relapsed/refractory high-risk neuroblastoma.
