EMPLICITI

Elotuzumab is a humanized recombinant monoclonal antibody directed to SLAMF7, a cell surface glycoprotein. Elotuzumab consists of the complementary determining regions (CDR) of the mouse antibody, MuLuc63, grafted onto human IgG1 heavy and kappa light chain frameworks. Elotuzumab is produced in NS0 cells by recombinant DNA technology. Elotuzumab has a theoretical mass of 148.1 kDa for the intact antibody. EMPLICITI (elotuzumab) is a sterile, nonpyrogenic, preservative-free lyophilized powder that is white to off-white, whole or fragmented cake in single-dose vials. EMPLICITI for Injection is supplied as 300 mg per vial and 400 mg per vial and requires reconstitution with Sterile Water for Injection, USP (13 mL and 17 mL, respectively) to obtain a solution with a concentration of 25 mg/mL. After reconstitution, each vial contains overfill to allow for withdrawal of 12 mL (300 mg) and 16 mL (400 mg). The reconstituted solution is colorless to slightly yellow, clear to slightly opalescent. Prior to intravenous infusion, the reconstituted solution is diluted with either 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP [see Dosage and Administration (2.6) ] . Each 300 mg single-dose vial of EMPLICITI also contains the following inactive ingredients: citric acid monohydrate (2.44 mg), polysorbate 80 (3.4 mg), sodium citrate (16.6 mg), and sucrose (510 mg). Each 400 mg single-dose vial of EMPLICITI also contains the following inactive ingredients: citric acid monohydrate (3.17 mg), polysorbate 80 (4.4 mg), sodium citrate (21.5 mg), and sucrose (660 mg).

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. Table 3: Infusion Rate for EMPLICITI 10 mg/kg Cycle 1, Dose 1 Cycle 1, Dose 2 Cycle 1, Dose 3 and 4 and All Subsequent Cycles Time Interval Rate Time Interval Rate Rate 0-30 min 0.5 mL/min 0-30 min 3 mL/min 30-60 min 1 mL/min 30 min or more 4 mL/min 5 mL/min 60 min or more 2 mL/min - - Initiate EMPLICITI infusion rate at 3 mL per minute for 20 mg/kg dose. 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 1 Dose 2 and all subsequent doses Time Interval Rate Rate 0-30 min 3 mL/min 30 min or more 4 mL/min 5 mL/min Adjust the infusion rate following a Grade 2 or higher infusion reaction [see Dosage and Administration (2.4) ] . Do not mix EMPLICITI with, or administer as an infusion with, other medicinal products. No physical or biochemical compatibility studies have been conducted to evaluate the coadministration of EMPLICITI with other agents. 2.6 Reconstitution and Preparation Calculation of Dose • Calculate the dose (mg) and determine the number of vials needed for the 10 mg/kg and 20 mg/kg dosage based on patient weight. • Determine the volume of sterile water for injection (SWFI) needed for reconstitution as shown in Table 5. Table 5: Reconstitution Instructions for EMPLICITI Strength Amount of Sterile Water for Injection, USP Required for Reconstitution Deliverable Volume of Reconstituted EMPLICITI in the Vial Postreconstitution Concentration * After reconstitution, each vial contains overfill to allow for withdrawal of 12 mL (300 mg) and 16 mL (400 mg), respectively. 300 mg vial 13 mL 12 mL* 25 mg/mL 400 mg vial 17 mL 16 mL* 25 mg/mL Reconstitution • Aseptically reconstitute each EMPLICITI vial with a syringe of adequate size and a less than or equal to 18-gauge needle (e.g., 17-gauge). A slight back pressure may be experienced during administration of the Sterile Water for Injection, USP, which is considered normal. • Hold the vial upright and swirl the solution by rotating the vial to dissolve the lyophilized cake. Invert the vial a few times in order to dissolve any powder that may be present on top of the vial or the stopper. Avoid vigorous agitation. DO NOT SHAKE. The lyophilized powder should dissolve in less than 10 minutes. • After the remaining solids are completely dissolved, allow the reconstituted solution to stand for 5 to 10 minutes. The reconstituted preparation results in a colorless to slightly yellow, clear to slightly opalescent solution. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Discard the solution if any particulate matter or discoloration is observed. Dilution • Once the reconstitution is completed, withdraw the necessary volume for the calculated dose from each vial, up to a maximum of 16 mL from 400 mg vial and 12 mL from 300 mg vial. • Further dilute with either 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP, into an infusion bag made of polyvinyl chloride or polyolefin. The final infusion concentration should range between 1 mg/mL and 6 mg/mL. • The volume of 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP should be adjusted so as not to exceed 5 mL/kg of patient weight at any given dose of EMPLICITI. Complete the EMPLICITI infusion within 24 hours of reconstitution of the EMPLICITI lyophilized powder. If not used immediately, the infusion solution may be stored under refrigeration conditions: 2°C to 8°C (36°F-46°F) and protected from light for up to 24 hours (a maximum of 8 hours of the total 24 hours can be at room temperature, 20°C to 25°C [68°F-77°F], and room light).

EMPLICITI in Combination with Lenalidomide and Dexamethasone [ELOQUENT-2] The safety data described in this section are based on the ELOQUENT-2 study, a randomized, open-label clinical trial in patients with previously treated multiple myeloma. In ELOQUENT-2, EMPLICITI 10 mg/kg was administered with lenalidomide and dexamethasone [see Clinical Studies (14) ] . For adverse reaction evaluation, EMPLICITI combined with lenalidomide and dexamethasone was compared with lenalidomide and dexamethasone alone. The mean age of the population was 66 years and 57% of patients were 65 years of age or older. Sixty percent (60%) of the population were male, 84% were white, 10% were Asian, and 4% were black. The Eastern Cooperative Oncology Group (ECOG) performance status was 0 in 47%, 1 in 44%, and 2 in 9% of patients. These data reflect exposure of 318 patients to EMPLICITI and 317 to control with a median number of cycles of 19 for EMPLICITI and 14 for control. Serious adverse reactions were reported in 65% of patients treated on the EMPLICITI arm and 57% for patients treated on the control arm. The most frequent serious adverse reactions in the EMPLICITI arm compared to the control arm were: pneumonia (15% vs. 11%), pyrexia (7% vs. 5%), respiratory tract infection (3.1% vs. 1.3%), anemia (2.8% vs. 1.9%), pulmonary embolism (3.1% vs. 2.5%), and acute renal failure (2.5% vs. 1.9%). The proportion of patients who discontinued any component of the treatment regimen due to adverse reactions as listed below was similar for both treatment arms; 6.0% for patients treated on the EMPLICITI arm and 6.3% for patients treated on the control. Adverse reactions occurring at a frequency of 10% or higher in the EMPLICITI arm and 5% or higher than the lenalidomide and dexamethasone arm for the randomized trial in multiple myeloma are presented in Table 6.

In ELOQUENT-3, EMPLICITI 10 mg/kg and 20 mg/kg was administered with pomalidomide and dexamethasone [see Clinical Studies (14) ] . For adverse reaction evaluation, EMPLICITI combined with pomalidomide and dexamethasone was compared with pomalidomide and dexamethasone alone. The mean age of the population was 66 years and 63% of patients were 65 years of age or older. Fifty-seven percent of the population were male, 78% were white, 20% were Asian, and none were black. The ECOG performance status was 0 in 43%, 1 in 46%, and 2 in 10% of patients. These data reflect exposure of 60 patients to EMPLICITI and 55 to control with a median number of cycles of 9 for EMPLICITI and 5 for control. Serious adverse reactions were reported in 70% of patients treated on the EMPLICITI arm and 60% for patients treated on the control arm. The most frequent serious adverse reactions in the EMPLICITI arm compared to the control arm were: pneumonia (13% vs. 11%) and respiratory tract infection (7% vs. 3.6%). The proportion of patients who discontinued any component of the treatment regimen due to adverse reactions were 5% of the patients in the EMPLICITI arm and 1.8% of the patients in the control arm. Adverse reactions occurring at a frequency of 10% or higher in the EMPLICITI arm and 5% or higher than the pomalidomide and dexamethasone arm for the randomized trial in multiple myeloma are presented in Table 9. Table 9: ELOQUENT-3: Adverse Reactions with a 10% or Higher Incidence for EMPLICITI-Treated Patients and a 5% or Higher Incidence than Pomalidomide and Dexamethasone-Treated Patients [All Grades] EMPLICITI + Pomalidomide and Dexamethasone N=60 Pomalidomide and Dexamethasone N=55 Adverse Reaction All Grades Grade 3/4 All Grades Grade 3/4 * The term pneumonia is grouping of the following terms: pneumonia, atypical pneumonia, lower respiratory tract infection, pneumoccocal sepsis, pneumonia bacterial, pneumonia influenza.

The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of incidence of antibodies to EMPLICITI in the studies described below with the incidences of antibodies in other studies or to other products may be misleading. Of 390 patients across four clinical studies including ELOQUENT-2 and in 53 patients in the ELOQUENT-3 trial, who were treated with EMPLICITI and evaluable for the presence of anti-product antibodies, 72 patients (18.5%) in the four clinical trials and 19 patients (36%) in the ELOQUENT-3 trial tested positive for treatment-emergent anti-product antibodies by an electrochemiluminescent (ECL) assay. In 63 (88%) of the 72 patients in the four clinical trials, anti-product antibodies occurred within the first 2 months of the initiation of EMPLICITI treatment and resolved by 2 to 4 months in 49 (78%) patients. In the ELOQUENT-3 trial, in all 19 patients, anti-product antibodies occurred within the first 2 months of the initiation of EMPLICITI treatment and were resolved by 2 to 3 months in 18 (95%) patients. Neutralizing antibodies post-treatment were detected in 19 of 299 patients in the four clinical trials and 2 of 53 patients in the ELOQUENT-3 trial who were evaluable for the presence of neutralizing antibodies.

7.1 Drug Interactions For important drug interactions involving lenalidomide, pomalidomide and dexamethasone, refer to their respective prescribing information. 7.2 Laboratory Test Interference EMPLICITI may be detected in the SPEP and serum immunofixation assays of myeloma patients and could interfere with correct response classification. A small peak in the early gamma region on SPEP that is IgGƙ on serum immunofixation may potentially be attributed to EMPLICITI, particularly in patients whose endogenous myeloma protein is IgA, IgM, IgD, or lambda light chain restricted. This interference can impact the determination of complete response and possibly relapse from complete response in patients with IgG kappa myeloma protein [see Warnings and Precautions (5.5) ].
