An immune-stimulating antibody for myeloma that works only in combination, adding benefit to lenalidomide or pomalidomide.
Elotuzumab is a monoclonal antibody against SLAMF7 (CS1), a surface protein on both myeloma cells and natural killer cells. It marks myeloma cells for NK-mediated antibody-dependent cellular cytotoxicity and simultaneously activates the NK cells, but it has no single-agent activity and is always combined with an immunomodulatory drug and dexamethasone. ELOQUENT-2 (2015) showed median progression-free survival of 19.4 versus 14.9 months when added to lenalidomide-dexamethasone in patients after 1 to 3 prior therapies, leading to US approval in 2015. ELOQUENT-3 (2018) supported a second approval with pomalidomide-dexamethasone after at least two therapies. CD38 antibodies have largely displaced it, but it remains an option in daratumumab-refractory disease and is generally well tolerated. The key idea is an antibody that works only by recruiting the patient's own immune cells.
Binds SLAMF7 (CS1) on myeloma cells and NK cells, enhancing NK-mediated ADCC; no single-agent activity.

Given by infusion or injection in a clinic or hospital outpatient department, so it is a Part B drug: Medicare pays 80% after the Part B deductible and the patient owes 20% coinsurance, uncapped in Original Medicare unless a Medigap policy applies.
Covered under the medical benefit with prior authorisation confirming diagnosis, biomarker status and line of therapy; site-of-care policies may steer infusions away from hospital outpatient departments.
20% Part B coinsurance on a high-cost infusion adds up quickly: Medigap Plan G or N, Medicare Advantage maximum out-of-pocket, Medicaid dual eligibility, or a charity fund are the usual buffers.
