Why is Elotuzumab Prescribed? (Indications)

Elotuzumab is used to treat multiple myeloma, a type of cancer in the bone marrow in adult patients whose cancer has returned after successful treatment or in patients who showed treatment failure with one to three cancer treating medications.

It is a monoclonal antibody that works by binding to the natural killer (NK) cells, a type of white blood cell and enhances the NK cells to identify and kill the myeloma or the cancer cells. 

When should Elotuzumab not to be taken? (Contraindications)

Elotuzumab should not be used in patients-

• Allergic to elotuzumab
• Pregnancy and breastfeeding
• Children under the age of 18 years
• Severe liver disease

What is the dosage of Elotuzumab?

The dose of elotuzumab is calculated based on the individual patient’s body weight and the recommended dose is 10 mg/kg body weight given every week during the first two cycles and for every two weeks for subsequent cycles.

Lenalidomide is also given to the patient as a dose of 25 mg by mouth from day 1 to day 21 of every 28-day cycle of elotuzumab treatment.

Patients should be pre-medicated with the following medications-

• Dexamethasone
• Diphenhydramine

• Acetaminophen or paracetamol

The dose of elotuzumab is adjusted based on the infusion-related side effects and the treatment with elotuzumab can be permanently stopped if the infusion-related side effects are severe.

How should Elotuzumab be taken?

• Elotuzumab comes in a powder form which should be mixed with sterile water. It should be given intravenously or directly into the vein by a health care provider in a hospital setting.

• Two doses of dexamethasone – a 28 mg dose given by mouth 3 to 24 hours before and an 8 mg dose given intravenously 45 to 90 minutes – should be administered before elotuzumab injection is given.

• When elotuzumab is not given on day 8 and day 22 of the 3rd, and the subsequent cycles, the dose of dexamethasone tablet should be increased to 40 mg instead of 28 mg.

• Diphenhydramine should be given as a 25 - 50 mg tablet or injection into the vein to prevent any infusion-related allergies.

• Ranitidine is given either as a 50 mg injection into the vein or a 150 mg tablet by mouth along with paracetamol 650 mg to 1000 mg tablet to be taken by mouth.

• Mix the vial contents in an environment free from contamination and diluted with 0.9% sodium chloride or 5% dextrose solution. The diluted mixture should be used within 24 hours of the diluted or reconstituted procedure.
