Other Medications In addition to dexamethasone, complete administration of the following medications 45 to 90 minutes prior to EMPLICITI infusion: • H1 blocker: diphenhydramine (25 to 50 mg orally or intravenously) or equivalent H1 blocker. • H2 blocker: ranitidine (50 mg intravenously or 150 mg orally) or equivalent H2 blocker. • Acetaminophen (650 to 1000 mg orally). 2.4 Dose Modifications If the dose of one drug in the regimen is delayed, interrupted, or discontinued, the treatment with the other drugs may continue as scheduled. However, if dexamethasone is delayed or discontinued, base the decision whether to administer EMPLICITI on clinical judgment (i.e., risk of hypersensitivity). If a Grade 2 or higher infusion reaction occurs during EMPLICITI administration, interrupt the infusion and institute appropriate medical and supportive measures. Upon resolution to Grade 1 or lower, restart EMPLICITI at 0.5 mL per minute and gradually increase at a rate of 0.5 mL per minute every 30 minutes as tolerated to the rate at which the infusion reaction occurred. Resume the escalation regimen if there is no recurrence of the infusion reaction (see Table 3 and Table 4). In patients who experience an infusion reaction, monitor vital signs every 30 minutes for 2 hours after the end of the EMPLICITI infusion. If the infusion reaction recurs, stop the EMPLICITI infusion and do not restart on that day [see Warnings and Precautions (5.1) ] . Severe infusion reactions may require permanent discontinuation of EMPLICITI therapy and emergency treatment. Dose delays and modifications for dexamethasone, pomalidomide and lenalidomide should be performed as recommended in their Prescribing Information. 2.5 Administration Administer the entire EMPLICITI infusion with an infusion set and a sterile, nonpyrogenic, low-protein-binding filter (with a pore size of 0.2 to 1.2 micrometer) using an automated infusion pump. Initiate EMPLICITI infusion at a rate of 0.5 mL per minute for 10 mg/kg dose. The infusion rate may be increased in a stepwise fashion as described in Table 3 if no infusion reactions develop. The maximum infusion rate should not exceed 5 mL per minute.

The infusion rate may be increased in a stepwise fashion as described in Table 4 if no infusion reactions develop. The maximum infusion rate should not exceed 5 mL per minute. Patients who have escalated to 5 mL/min at 10 mg/kg dose must decrease the rate to 3 mL/min at the first infusion at 20 mg/kg. Table 4: Infusion Rate for EMPLICITI 20 mg/kg Dose

WARNINGS AND PRECAUTIONS • Infusion reactions: Premedication is required. Interrupt EMPLICITI for Grade 2 or higher and permanently discontinue for severe infusion reaction. ( 2.3 , 2.4 , 5.1) • Infections: Monitor for fever and other signs of infection and treat promptly. (5.2) • Second Primary Malignancies (SPM): Higher incidences of SPM were observed in a controlled clinical trial of patients with multiple myeloma receiving EMPLICITI. (5.3) • Hepatotoxicity: Monitor liver function and stop EMPLICITI if hepatotoxicity is suspected. (5.4) • Interference with determination of complete response: EMPLICITI can interfere with assays used to monitor M-protein. This interference can impact the determination of complete response. (5.5) 5.1 Infusion Reactions EMPLICITI can cause infusion reactions. Infusion reactions were reported in 10% of patients treated with EMPLICITI in the ELOQUENT-2 trial and 3.3% in the ELOQUENT-3 trial. In the ELOQUENT-2 trial, all reports of infusion reaction were Grade 3 or lower. In the ELOQUENT-2 trial, Grade 3 infusion reactions occurred in 1% of patients. The most common symptoms of an infusion reaction included fever, chills, and hypertension. Bradycardia and hypotension also developed during infusions. In the ELOQUENT-2 trial, 5% of patients required interruption of the administration of EMPLICITI for a median of 25 minutes due to infusion reactions, and 1% of patients discontinued due to infusion reactions. Of the patients who experienced an infusion reaction, 70% (23/33) had them during the first dose. In the ELOQUENT-3 trial, the only infusion reaction symptom was chest discomfort (2%), which was Grade 1. All patients in the ELOQUENT-3 trial who experienced an infusion reaction had them during the first treatment cycle. Administer premedication consisting of dexamethasone, antihistamines (H1 and H2 blockers) and acetaminophen prior to EMPLICITI infusion [see Dosage and Administration (2.3) ]. Interrupt EMPLICITI infusion for Grade 2 or higher infusion reactions and institute appropriate medical management [see Dosage and Administration (2.4) ]. 5.2 Infections In the ELOQUENT-2 trial (N=635), infections were reported in 81% of patients in EMPLICITI combined with lenalidomide and dexamethasone (E-Ld) arm and 74% in lenalidomide and dexamethasone (Ld). In the ELOQUENT-3 trial (N=115), infections were reported in 65% of patients in both EMPLICITI combined with pomalidomide and dexamethasone (E-Pd) arm and in pomalidomide and dexamethasone (Pd) arm. In the ELOQUENT-2 trial, Grade 3 to 4 infections were noted in 28% and 24% of E-Ld- and Ld-treated patients and in the ELOQUENT-3 trial, 13% and 22% of E-Pd- and Pd-treated patients, respectively. Discontinuations due to infections occurred in 3.5% of E-Ld-treated and 4.1% of Ld-treated patients in the ELOQUENT-2 trial and 7% of E-Pd-treated and 5% of Pd-treated patients in the ELOQUENT-3 trial. Fatal infections were reported in 2.5% and 2.2% of E-Ld- and Ld-treated patients in the ELOQUENT-2 trial and 5% and 3.6% of E-Pd- and Pd-treated patients in the ELOQUENT-3 trial. Opportunistic infections were reported in 22% of patients in the E-Ld arm and 13% of patients in the Ld arm in the ELOQUENT-2 trial and 10% of patients in the E-Pd arm and 9% of patients in the Pd arm in the ELOQUENT-3 trial. In the ELOQUENT-2 trial, fungal infections occurred in 10% of patients in the E-Ld arm and 5% of patients in the Ld arm. Herpes zoster was reported in 14% of patients treated with E-Ld and 7% of patients treated with Ld in the ELOQUENT-2 trial and 5% of patients treated with E-Pd and 1.8% of patients treated with Pd in the ELOQUENT-3 trial. Monitor patients for development of infections and treat promptly. 5.3 Second Primary Malignancies In the ELOQUENT-2 trial (N=635), invasive second primary malignancies (SPM) have been observed in 9% of patients treated with E-Ld and 6% of patients treated with Ld and in the ELOQUENT-3 trial (N=115) in 1.8% of patients treated with Pd and in none of the patients treated with E-Pd. In the ELOQUENT-2 trial, the rate of hematologic malignancies were the same between E-Ld and Ld treatment arms (1.6%). Solid tumors were reported in 3.5% and 2.2% of E-Ld- and Ld-treated patients, respectively. Skin cancer was reported in 4.4% and 2.8% of patients treated with E-Ld and Ld, respectively. Monitor patients for the development of second primary malignancies. 5.4 Hepatotoxicity In the ELOQUENT-2 trial (N=635), elevations in liver enzymes (aspartate transaminase/alanine transaminase [AST/ALT] greater than 3 times the upper limit, total bilirubin greater than 2 times the upper limit, and alkaline phosphatase less than 2 times the upper limit) consistent with hepatotoxicity were reported in 2.5% and 0.6% of E-Ld- and Ld-treated patients. Two patients experiencing hepatotoxicity were not able to continue treatment; however, 6 out of 8 patients had resolution and were able to continue treatment. Monitor liver enzymes periodically. Stop EMPLICITI upon Grade 3 or higher elevation of liver enzymes. After return to baseline values, continuation of treatment may be considered. 5.5 Interference with Determination of Complete Response EMPLICITI is a humanized IgG kappa monoclonal antibody that can be detected on both the serum protein electrophoresis (SPEP) and immunofixation (IFE) assays used for the clinical monitoring of endogenous M-protein [see Drug Interactions (7.2) ] . This interference can impact the determination of complete response and possibly relapse from complete response in patients with IgG kappa myeloma protein.

CONTRAINDICATIONS None. None (4)

Mechanism of Action Elotuzumab is a humanized IgG1 monoclonal antibody that specifically targets the SLAMF7 (Signaling Lymphocytic Activation Molecule Family member 7) protein. SLAMF7 is expressed on myeloma cells independent of cytogenetic abnormalities. SLAMF7 is also expressed on Natural Killer (NK) cells, plasma cells, and at lower levels on specific immune cell subsets of differentiated cells within the hematopoietic lineage. Elotuzumab directly activates NK cells through the SLAMF7 pathway. Elotuzumab also targets SLAMF7 on myeloma cells and interacts with Fc receptors on effector cells to mediate the killing of myeloma cells through antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). In nonclinical models, the combination of elotuzumab and lenalidomide resulted in enhanced activation of NK cells that was greater than the effects of either agent alone and increased anti-tumor activity in vitro and in vivo. Elotuzumab has also demonstrated increased anti-tumor activity when combined with pomalidomide in vivo.
