Premedication
Dexamethasone
When EMPLICITI is used in combination with lenalidomide or pomalidomide and dexamethasone, divide dexamethasone into an oral and intravenous dose and administer as shown in Table 1 and Table 2 [see Dosage and Administration (2.1 , 2.2) ] .
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).
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.
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.
| 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.
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.
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.
| 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).
DOSAGE FORMS AND STRENGTHS
For injection: 300 mg or 400 mg of elotuzumab as a white to off-white lyophilized powder in a single-dose vial for reconstitution.
USE IN SPECIFIC POPULATIONS
Pregnancy: Embryo-fetal toxicity in combination with lenalidomide and dexamethasone or pomalidomide and dexamethasone. (8.1)
Pregnancy
Risk Summary
There are no available data on EMPLICITI use in pregnant women to inform a drug associated risk of major birth defects and miscarriage. Animal reproduction studies have not been conducted with elotuzumab.
EMPLICITI is administered in combination with lenalidomide and dexamethasone or pomalidomide and dexamethasone. Lenalidomide and pomalidomide can cause embryo-fetal harm and are contraindicated for use in pregnancy. Refer to the lenalidomide, pomalidomide and dexamethasone prescribing information for additional information. Lenalidomide and pomalidomide are only available through a REMS program.
The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Lactation
Risk Summary
There are no data on the presence of EMPLICITI in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in the breastfed child from elotuzumab administered in combination with lenalidomide and dexamethasone or pomalidomide and dexamethasone, advise lactating women not to breastfeed during treatment with EMPLICITI. Refer to the lenalidomide, pomalidomide and dexamethasone prescribing information for additional information.
Females and Males of Reproductive Potential
Pregnancy Testing
Refer to the lenalidomide and pomalidomide labeling for pregnancy testing requirements prior to initiating treatment in females of reproductive potential.
When EMPLICITI is used with lenalidomide or pomalidomide, there is a risk of fetal harm, including severe life-threatening human birth defects associated with lenalidomide and pomalidomide, and the need to follow requirements regarding pregnancy avoidance, including testing.
Contraception
Females
Refer to the lenalidomide and pomalidomide labeling for contraception requirements prior to initiating treatment in females of reproductive potential.
Males
Lenalidomide and pomalidomide are present in the blood and semen of patients receiving the drug. Refer to the lenalidomide and pomalidomide full prescribing information for requirements regarding contraception and the prohibitions against blood and/or sperm donation due to presence and transmission in blood and/or semen and for additional information.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients.
Geriatric Use
Of the 646 patients across treatment groups in the ELOQUENT-2 randomized trial designed to evaluate the use of EMPLICITI in combination with lenalidomide and low-dose dexamethasone in multiple myeloma, 57% were 65 years of age or older; the number of patients 65 years or older was similar between treatment groups. No overall differences in efficacy or safety were observed between patients 65 years or older and younger patients (less than 65 years of age).
Of the 117 patients across treatment groups in the ELOQUENT-3 randomized trial designed to evaluate the use of EMPLICITI in combination with pomalidomide and low-dose dexamethasone in multiple myeloma, 62% were 65 years of age or older; the number of patients 65 years or older was similar between treatment groups. This study did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.
CONTRAINDICATIONS
None.
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)
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) ].
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.
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.
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.
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.
ADVERSE REACTIONS
The following clinically significant adverse reactions are described in detail in other sections of the label:
- Infusion reaction [see Warnings and Precautions (5.1) ] .
- Infections [see Warnings and Precautions (5.2) ] .
- Second Primary Malignancies [ see Warnings and Precautions (5.3) ] .
- Hepatotoxicity [see Warnings and Precautions (5.4) ] .
- Interference with determination of complete response [see Warnings and Precautions (5.5) ] .
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
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.

EMPLICITI in Combination with Pomalidomide and Dexamethasone [ELOQUENT-3]
The safety data described in this section are based on ELOQUENT-3, a randomized, open-label clinical trial in patients with previously treated multiple myeloma. 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.

Immunogenicity
As with all therapeutic proteins, there is a potential for immunogenicity to EMPLICITI. 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.
DRUG INTERACTIONS
Drug Interactions
For important drug interactions involving lenalidomide, pomalidomide and dexamethasone, refer to their respective prescribing information.
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) ].
DESCRIPTION
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).
CLINICAL PHARMACOLOGY
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.
Pharmacodynamics
Cardiac Electrophysiology
EMPLICITI does not prolong the QT interval to any clinically relevant extent when administered with lenalidomide and dexamethasone at the recommended dose or as monotherapy (at a dose 2 times the recommended dose).
Pharmacokinetics
Elotuzumab exhibits nonlinear pharmacokinetics (PK) resulting in greater than proportional increases in area under the concentration-time curve (AUC) indicative of target-mediated clearance. The administration of the recommended 10 mg/kg EMPLICITI regimen with lenalidomide and dexamethasone is predicted to result in geometric mean (CV%) steady-state trough concentrations of 194 μg/mL (52%). The administration of the recommended EMPLICITI regimen with pomalidomide and dexamethasone is predicted to result in geometric mean (CV%) steady-state trough concentrations of 124 μg/mL (59%).
Elimination
The clearance of elotuzumab in combination with lenalidomide and dexamethasone decreased from a geometric mean (CV%) of 17.5 (21.2%) to 5.8 (31%) mL/day/kg with an increase in dose from 0.5 (i.e., 0.05 times the recommended dosage) to 20 mg/kg (i.e., 2 times the recommended dosage). When elotuzumab is administered with lenalidomide and dexamethasone, approximately 97% of the maximum steady-state concentration is predicted to be eliminated with a geometric mean (CV%) of 82.4 (48%) days. When elotuzumab is administered with pomalidomide and dexamethasone, approximately 97% of the maximum steady-state concentration is predicted to be eliminated with a geometric mean (CV%) of 78 (42%) days.
Specific Populations
Clinically significant differences were not observed in the PK of elotuzumab based on age (37 to 88 years), sex, race, baseline lactate dehydrogenase, albumin, renal impairment (creatinine clearance (CLcr) 15 to 89 mL/min), end-stage renal disease (CLcr <15 mL/min) with or without hemodialysis, mild hepatic impairment (total bilirubin ≤ upper limit of normal (ULN) and aspartate transaminase (AST) > ULN OR total bilirubin 1 to 1.5 times the ULN and AST any value), and coadministration with lenalidomide/dexamethasone or pomalidomide/dexamethasone. The PK of elotuzumab in patients with moderate (total bilirubin > 1.5 to 3 times the ULN and AST any value) to severe (total bilirubin > 3 times the ULN and AST any value) hepatic impairment is unknown.
The clearance of elotuzumab increased with increasing body weight supporting a weight-based dose.
NONCLINICAL TOXICOLOGY
Carcinogenesis, Mutagenesis, Impairment of Fertility
No carcinogenicity or mutagenicity data are available for elotuzumab in animals or humans. Fertility studies have not been performed for elotuzumab.
CLINICAL STUDIES
ELOQUENT-2 (NCT01239797)
The efficacy and safety of EMPLICITI in combination with lenalidomide and dexamethasone were evaluated in ELOQUENT-2, a randomized, open-label trial in patients with multiple myeloma who had received one to three prior therapies and had documented progression following their most recent therapy.
Eligible patients were randomized in a 1:1 ratio to receive either EMPLICITI in combination with lenalidomide and low-dose dexamethasone or lenalidomide and low-dose dexamethasone. Treatment was administered in 4-week cycles until disease progression or unacceptable toxicity. EMPLICITI 10 mg/kg was administered intravenously each week for the first 2 cycles and every 2 weeks thereafter. Prior to EMPLICITI infusion, dexamethasone was administered as a divided dose: an oral dose of 28 mg and an intravenous dose of 8 mg. In the control group and on weeks without EMPLICITI, dexamethasone 40 mg was administered as a single oral dose weekly. Lenalidomide 25 mg was taken orally once daily for the first 3 weeks of each cycle. Assessment of tumor response was conducted every 4 weeks.
A total of 646 patients were randomized to receive treatment: 321 to EMPLICITI in combination with lenalidomide and low-dose dexamethasone and 325 to lenalidomide and low-dose dexamethasone.
Demographics and baseline disease characteristics were balanced between treatment arms. The median age was 66 years (range, 37-91); 57% of patients were 65 years or older; 60% of patients were male; whites comprised 84% of the study population, Asians 10%, and blacks 4%. The ECOG performance status was 0 in 47%, 1 in 44%, and 2 in 9% of patients, and ISS Stage was I in 43%, II in 32%, and III in 21% of patients. The cytogenetic categories of del 17p and t(4;14) were present in 32% and 9% of patients, respectively. The median number of prior therapies was 2. Thirty-five percent (35%) of patients were refractory (progression during or within 60 days of last therapy) and 65% were relapsed (progression after 60 days of last therapy). Prior therapies included stem cell transplant (55%), bortezomib (70%), melphalan (65%), thalidomide (48%), and lenalidomide (6%).
The efficacy of EMPLICITI was evaluated by progression-free survival (PFS) as assessed by hazard ratio, and overall response rate (ORR) as determined by a blinded Independent Review Committee using the European Group for Blood and Marrow Transplantation (EBMT) response criteria. Efficacy results are shown in Table 12 and Figure 1. The median number of treatment cycles was 19 for the EMPLICITI group and 14 for the comparator arm with a minimum follow-up of two years.
A pre-planned final overall survival (OS) analysis was performed after at least 427 deaths occurred. The minimum follow-up was 70.6 months. The OS results at final analysis reached statistical significance. A significantly longer OS was observed in patients in the E-Ld arm compared to patients in Ld arm, representing an 18% reduction in the risk of death. Efficacy results are presented in Table 12 and Figure 2.

ELOQUENT-3 (NCT02654132)
The efficacy and safety of EMPLICITI in combination with pomalidomide and dexamethasone were evaluated in ELOQUENT-3, a randomized, open-label trial in patients with relapsed or refractory multiple myeloma.
Eligible patients were randomized in a 1:1 ratio to receive either EMPLICITI in combination with pomalidomide and low-dose dexamethasone or pomalidomide and low-dose dexamethasone. Treatment was administered in 4-week cycles until disease progression or unacceptable toxicity. EMPLICITI 10 mg/kg was administered intravenously each week for the first 2 cycles and 20 mg/kg every 4 weeks thereafter.
Prior to EMPLICITI infusion, dexamethasone was administered. Dexamethasone was administered on day 1, 8, 15 and 22 of each cycle. On weeks with EMPLICITI infusion, dexamethasone was administered as a divided dose: subjects 75 years or younger, an oral dose of 28 mg and an intravenous dose of 8 mg, and in subjects older than 75 years an oral dose of 8 mg and an intravenous dose of 8 mg. On weeks without an EMPLICITI infusion and in the control group, dexamethasone was administered in subjects 75 years or younger as an oral dose of 40 mg and in subjects older than 75 years as an oral dose of 20 mg dexamethasone was administered orally. Assessment of tumor response was conducted every 4 weeks.
A total of 117 patients were randomized to receive treatment: 60 to EMPLICITI in combination with pomalidomide and low-dose dexamethasone and 57 to pomalidomide and low-dose dexamethasone.
Demographics and baseline disease characteristics were balanced between treatment arms. The median age was 67 years (range, 36-81); 62% of patients were 65 years or older; 57% of patients were male; whites comprised 77% of the study population, Asians 21%, and blacks 1%. The ECOG performance status was 0 in 44%, 1 in 46%, and 2 in 10% of patients, and ISS Stage was I in 50%, II in 38%, and III in 12% of patients. The chromosomal lab abnormalities as determined by FISH of del 17p and t(4;14) were present in 5% and 11% of patients, respectively. The median number of prior therapies was 3. Eighty-seven percent (87%) of patients were refractory to lenalidomide, 80% refractory to a proteasome inhibitor, 70% were refractory to both lenalidomide and a proteasome inhibitor. Prior therapies included stem cell transplant (55%), bortezomib (100%), lenalidomide (99%), cyclophosphamide (66%), melphalan (63%), carfilzomib (21%), and daratumumab (3%).
The efficacy of EMPLICITI was evaluated by progression-free survival (PFS) and overall response rate (ORR) as determined by the investigator. Efficacy results are shown in Table 13 and Figure 3. The median number of treatment cycles was 9 for the EMPLICITI group and 5 for the comparator arm with a minimum follow-up of 9.1 months.
A pre-planned final OS analysis was performed after at least 78 deaths occurred. The minimum follow-up was 45.0 months. A longer OS was observed in patients in the E-Pd arm compared to patients in the Pd arm. Efficacy results are presented in Table 13 and Figure 4.
