( 2.2 ) The recommended dosage of SARCLISA ESCENA is 1,400 mg administered as subcutaneous injection with the CirCLIQ™ On-Body Delivery System (OBDS) or with a syringe and infusion set for manual administration. See full prescribing information for SARCLISA ESCENA schedules of administration and drugs used in combination. ( 2.1 ) 2.1 Important Dosage Information SARCLISA ESCENA and intravenous isatuximab-irfc have different dosage and administration instructions [see Dosage and Administration (2.2) ] . SARCLISA ESCENA is for subcutaneous use only. Check the product label to ensure that the correct formulation (SARCLISA ESCENA or intravenous isatuximab-irfc) is being prescribed and administered. 2.2 Recommended Dosage Administer premedications before SARCLISA ESCENA administration [see Dosage and Administration (2.3) ] . SARCLISA ESCENA should be administered by a health care professional [see Warnings and Precautions (5.1) ] . Patients currently receiving intravenous isatuximab-irfc may transition to SARCLISA ESCENA solution for injection after the completion of the first cycle. The recommended dose of SARCLISA ESCENA is 1,400 mg administered as a subcutaneous injection with the CirCLIQ On-Body Delivery System (OBDS) or with a syringe and infusion set for manual administration, in combination with pomalidomide and dexamethasone or in combination with carfilzomib and dexamethasone, or in combination with bortezomib, lenalidomide, and dexamethasone. SARCLISA ESCENA dosing schedules are provided in Tables 1 and 2 [see Clinical Studies (14) ] . Table 1: SARCLISA ESCENA Dosing Schedule in Combination with Pomalidomide and Dexamethasone or in Combination with Carfilzomib and Dexamethasone Cycles Dosing schedules Cycle 1 (28-day cycle) Days 1, 8, 15, and 22 (weekly) Cycle 2 and beyond (28-day cycles) Days 1 and 15 (every 2 weeks) Table 2: SARCLISA ESCENA Dosing Schedule in Combination with Bortezomib, Lenalidomide, and Dexamethasone Cycles Dosing schedule Cycle 1 (28-day cycle) Days 1, 8, 15, 22 (weekly) Cycles 2 to 12 (28-day cycles) Days 1 and 15 (every 2 weeks) Cycles 13 and beyond (28-day cycles) Day 1 (every 4 weeks) Treatment is repeated until disease progression or unacceptable toxicity. SARCLISA ESCENA is used in combination with pomalidomide and dexamethasone or in combination with carfilzomib and dexamethasone or in combination with bortezomib, lenalidomide, and dexamethasone. For dosing instructions of combination agents administered with SARCLISA ESCENA, see Clinical Studies (14) and manufacturer's prescribing information. Missed SARCLISA ESCENA Doses If a planned dose of SARCLISA ESCENA is missed, administer the dose as soon as possible and adjust the treatment schedule accordingly, maintaining the treatment interval. 2.3 Recommended Premedications and Antimicrobial Prophylaxis Recommended Premedications Administer the following premedications 15 to 60 minutes prior to SARCLISA ESCENA administration to reduce the risk and severity of systemic administration reactions [see Warnings and Precautions (5.1) ] : When administered in combination with SARCLISA ESCENA and pomalidomide: Dexamethasone 40 mg orally or intravenously (or 20 mg orally or intravenously for patients 75 years of age or older). When administered in combination with SARCLISA ESCENA and carfilzomib: Dexamethasone 20 mg orally or intravenously. When administered in combination with SARCLISA ESCENA, bortezomib, and lenalidomide: Dexamethasone 20 mg orally. Leukotriene receptor antagonist, at cycle 1 only (Days 1, 8, 15, and 22). Acetaminophen 650 mg to 1,000 mg orally. Diphenhydramine 25 mg to 50 mg orally or intravenously (or equivalent). The intravenous route of diphenhydramine is preferred for at least the first 4 administrations of SARCLISA ESCENA. The above recommended dose of dexamethasone (orally or intravenously) corresponds to the total dose to be administered before SARCLISA ESCENA administration as part of the premedication and part of the backbone treatment [see Clinical Studies (14) ]. If no systemic administration reaction occurs during Cycle 1, assess patient specific factors and consider omitting subsequent premedication during future treatment cycles. Recommended Antimicrobial Prophylaxis Initiate antibacterial and antiviral prophylaxis (such as herpes zoster prophylaxis) if needed based on standard guidelines [see Warnings and Precautions (5.2 , 5.3) ] . 2.4 Dosage Modifications for Adverse Reactions No dose reduction of SARCLISA ESCENA is recommended. Dose delay or omission may be required [see Warnings and Precautions (5.1 , 5.2) ] . 2.5 Preparation SARCLISA ESCENA is only for abdominal subcutaneous administration using: CirCLIQ On-Body Delivery System (OBDS ) OR 20 mL syringe and infusion set (manual administration using commercially available syringe and infusion set). SARCLISA ESCENA should be administered by a healthcare provider. To prevent medication errors, check SARCLISA ESCENA vial label to ensure it is the correct medication for subcutaneous use (vial with green cap). Do not administer SARCLISA ESCENA intravenously. SARCLISA ESCENA is ready to use and should not be diluted. Prepare and administer SARCLISA ESCENA subcutaneously using clean technique. Prior to use‚ allow SARCLISA ESCENA to reach ambient temperature between 18°C to 28°C (64°F to 82°F) for approximately 20 minutes. Keep the unpunctured vial in the original carton prior to use to protect from light. Do not heat. Do not shake. Once the vial has been taken out of the refrigerator, it must not be returned to the refrigerator. Unpunctured vials may be stored at ambient temperature between 18°C to 28°C (64°F to 82°F) for a single period of up to 24 hours. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. The solution may contain a few translucent to white particles. SARCLISA ESCENA should not be used if the solution is cloudy or discolored, or if particles other than those described above are present [see Dosage Forms and Strengths (3) ] . Preparation with CirCLIQ On-Body Delivery System Refer to the Instructions for Use for CirCLIQ OBDS provided with the device for full preparation and administration information. Once the vial is punctured, the injection with the CirCLIQ On-Body Injector should be performed as soon as possible. If the injection is not completed within 4 hours, discard the vial and the On-Body Delivery System. Preparation with syringe and infusion set for manual administration Before you begin, collect your supplies: The syringe must be a 20 mL polypropylene syringe with Luer-fitting connector. The transfer needle with filter must be made of 18G stainless steel with 5-micron filter and Luer-fitting connector. The subcutaneous infusion set must have a 23G stainless steel needle for administration and tubing up to 12 inches (30 cm) length made of polyethylene, or polyvinyl chloride (PVC), with a Luer-fitting connector. Check the expiration date. Remove green vial cap and wipe vial rubber stopper with an alcohol wipe and allow to air dry. Attach the transfer needle with 5-micron filter to the syringe and fill the syringe. Withdraw the full content of the SARCLISA ESCENA vial into a 20 mL compatible syringe. Note: if the syringe containing SARCLISA ESCENA is not used immediately: Remove the transfer needle with filter. Attach a syringe closing cap to the syringe. Label the syringe with the SARCLISA ESCENA peel-off label provided in the vial carton and as per institutional standards. Store it for up to 4 hours at room temperature between 15°C to 25°C (59°F to 77°F) and ambient light, including the administration time. Discard after 4 hours, if not used. Attach the subcutaneous infusion set to the syringe. Prime the syringe and subcutaneous infusion set with SARCLISA ESCENA. Note: To avoid needle clogging, attach the subcutaneous infusion set to the syringe immediately prior to injection. 2.6 Administration On the days when both SARCLISA ESCENA and carfilzomib are administered, administer dexamethasone first, followed by SARCLISA ESCENA administration, then followed by carfilzomib infusion. SARCLISA ESCENA is only for abdominal subcutaneous administration. Data are only available with an injection performed into the abdomen. Change (rotate) the site of each subcutaneous administration – at least 1 inch (2.5 cm) from previous injection site - with every injection to avoid accumulation of fatty tissue. Do not inject other medications in the area where SARCLISA ESCENA is injected. Do not inject into areas where the skin is injured, tender, red, hot, has scars, or is excessively hairy. Administration with CirCLIQ On-Body Delivery System Refer to the Instructions for Use for CirCLIQ OBDS provided with the device for full preparation and administration information. Do not inject other medications in the area where SARCLISA ESCENA is injected. Administration with syringe and infusion set for manual administration Prepare injection site and insert needle. Wipe injection site with an alcohol swab and allow it to dry. Avoid injecting within 2 inches (5 cm) around the belly button. Remove protective needle cover. Pinch skin at the injection site on the abdomen. It is important to pinch enough skin to inject under the skin and not into the muscle. Insert needle at a 45-degree angle with a quick, dart-like motion. Note: Try to limit needle and syringe movement during the injection. If needed, secure the subcutaneous infusion set in place with a bandage. Inject 10 mL of SARCLISA ESCENA subcutaneously into the abdomen, over approximately 6 minutes. Pause or slow down delivery rate if the patient experiences pain. In the event pain is not alleviated by pausing or slowing down delivery rate, a second injection site may be chosen on the opposite side of the abdomen to deliver the remainder of the dose." ], "dosage_and_administration_table": [ "

( 4 )" ], "warnings_and_cautions": [ "5 WARNINGS AND PRECAUTIONS Hypersensitivity and Other Administration Reactions: In case of grade ≥2 systemic administration reaction (SAR), interrupt SARCLISA ESCENA and manage medically. In case of grade 4 SAR, permanently discontinue SARCLISA ESCENA. ( 5.1 ) Neutropenia : Monitor complete blood cell counts periodically during treatment. Monitor patients with neutropenia for signs of infection. SARCLISA ESCENA dose delays and the use of colony-stimulating factor may be required to allow improvement of neutrophil count. ( 5.2 ) Infections : SARCLISA ESCENA may cause serious and fatal infections. Monitor patients for signs and symptoms of infection and treat appropriately. ( 5.3 ) Second Primary Malignancies (SPM) : Monitor patients for the development of second primary malignancies. ( 5.4 ) Laboratory Test Interference : Interference with Serological Testing (Indirect Antiglobulin Test): Type and screen patients prior to starting treatment. Inform blood banks that a patient has received isatuximab-irfc. ( 5.5 , 7.1 ) Interference with Serum Protein Electrophoresis and Immunofixation Tests: isatuximab-irfc may interfere with the assays used to monitor M-protein, which may impact the determination of complete response. ( 5.5 , 7.1 ) Embryo-Fetal Toxicity : Can cause fetal harm. Advise patients of the potential risk to a fetus and to use effective contraception. ( 5.6 , 8.1 , 8.3 ) 5.1 Hypersensitivity and Other Administration Reactions SARCLISA ESCENA can cause both systemic administration-related reactions (SARs), including severe or life-threatening reactions, and local injection-site reactions. Systemic Administration Reactions In a pooled safety population of 411 patients with multiple myeloma who received SARCLISA ESCENA in combination with pomalidomide and dexamethasone (Pd), with carfilzomib and dexamethasone (Kd), and with bortezomib, lenalidomide, and dexamethasone (VRd) (IRAKLIA, IZALCO, and IsaSoCut, respectively, N=411), SARs occurred in 3.2% (Grade 1: 2.2%, Grade 2: 0.7%, Grade 3: 0.2%) of patients. SARs occurred at the first administration in 1.9% of patients and at subsequent administrations in 1.5% of patients. The median time to onset was 4 hours (range: 12 minutes to 3 days). The most frequently reported symptoms of SARs (all below 1%) were pyrexia and dyspnea, and Grade ≥3 symptoms was dyspnea (not collected in IsaSoCut study) [see Dosage and Administration (2.3) and Adverse Reactions (6.1) ] . In multiple myeloma clinical trials with intravenous isatuximab-irfc, anaphylactic reactions occurred in <1% of patients. To decrease the risk and severity of SARs, premedicate patients prior to SARCLISA ESCENA administration with leukotriene receptor antagonists (at cycle 1 only), acetaminophen, diphenhydramine, or equivalent, and dexamethasone [see Dosage and Administration (2.2) ] . In case of grade 2 SAR during SARCLISA ESCENA administration, stop current administration and do not complete it. Administer additional premedication, as needed, for subsequent SARCLISA ESCENA administration. In case of grade 3 SAR during SARCLISA ESCENA administration, stop current administration and do not complete it. SARCLISA ESCENA administration may be resumed at the next planned administration. In case of a third occurrence of a grade 3 SAR, permanently discontinue SARCLISA ESCENA treatment. In case of grade 4 SAR, permanently discontinue SARCLISA ESCENA treatment. Injection Site Reactions In clinical trials of SARCLISA ESCENA in combination with Pd, Kd, or VRd (IRAKLIA, IZALCO, and IsaSoCut, respectively, N=411), injection site reactions (ISRs) with SARCLISA ESCENA administration were reported in 9% (8% Grade 1 and 1.5% Grade 2) of patients and in 0.86% of injections. Among the SARCLISA ESCENA injections with ISRs, 82% occurred the day of the administration and 4.2% were delayed by at least 3 days. With SARCLISA ESCENA-Pd and SARCLISA ESCENA-Kd, 5% of patients experienced symptoms of ISR (not collected in IsaSoCut study). The most frequent (≥1%) symptoms of ISR were injection site erythema (3.3%), injection site swelling (2.1%), and injection site pain (1.5%). In case of grade 2 ISR during administration of SARCLISA ESCENA, interrupt it and resume it only after recovery to grade ≤1 with pauses during the administration (if using OBDS) or a slower administration (if manual injection). If the Grade 2 ISR occurs after the administration, continue SARCLISA ESCENA treatment after recovery to grade ≤1. In case of grade 3 or 4 ISR, permanently discontinue SARCLISA ESCENA treatment. In case SARCLISA ESCENA administration using CirCLIQ OBDS needs to be paused, please refer to the OBDS Instruction For Use (IFU). 5.2 Neutropenia Neutropenia was reported in patients receiving SARCLISA ESCENA subcutaneously in combination with Pd, Kd, or VRd. In clinical trials of SARCLISA ESCENA (IRAKLIA, IZALCO, and IsaSoCut, N=411), neutropenia occurred in 86% of patients based on laboratory value. Grade 3–4 neutropenia occurred in 66% of patients based on laboratory value. Febrile neutropenia was reported in 3.4% and neutropenic infections occurred in 13% of patients [see Adverse Reactions (6.1) ] . Monitor complete blood cell counts periodically during treatment. Monitor patients with neutropenia for signs of infection. In case of grade 4 neutropenia, delay or omit SARCLISA ESCENA dose until neutrophil count recovery to at least 1 × 10 9 /L, and provide supportive care with growth factors, according to institutional guidelines [see Dosage and Administration (2.3) ] . 5.3 Infections SARCLISA ESCENA can cause severe, life-threatening, or fatal infections. In patients who received SARCLISA ESCENA subcutaneously in combination with Pd, Kd, or VRd (IRAKLIA, IZALCO, and IsaSoCut, respectively, N=411), fatal infections occurred in 2.9% of patients, serious infections occurred in 29% of patients, and Grade ≥3 infections in 29% of patients. The most commonly reported infections (≥10%) were pneumonia (21%), upper respiratory tract infection (19%), and Covid-19 (12%). The most frequent serious infection (≥5%) was pneumonia (17%) [see Adverse Reactions (6.1) ]. Patients receiving SARCLISA ESCENA should be closely monitored for signs of infection and appropriate standard therapy instituted. Antibacterial and antiviral prophylaxis (such as herpes zoster prophylaxis) should be considered during treatment [see Dosage and Administration (2.3) ] . 5.4 Second Primary Malignancies Second primary malignancies were reported in 3.9% of patients in clinical trials with SARCLISA ESCENA in combination with Pd, Kd, and VRd (IRAKLIA, IZALCO, and IsaSoCut, respectively, N=411). Monitor patients for the development of second primary malignancies and initiate treatment as indicated. 5.5 Laboratory Test Interference Interference with Serological Testing (Indirect Antiglobulin Test) Isatuximab-irfc binds to CD38 on red blood cells (RBCs) and may result in a false positive indirect antiglobulin test (indirect Coombs test). This interference with the indirect Coombs test may persist for at least 6 months after the last administration of intravenous isatuximab-irfc. The indirect antiglobulin test was positive during intravenous isatuximab-irfc-Pd treatment in 68% of the tested patients, and during intravenous isatuximab-irfc-Kd treatment in 63% of patients. In patients with a positive indirect antiglobulin test, blood transfusions were administered without evidence of hemolysis. ABO/RhD typing was not affected by intravenous isatuximab-irfc treatment. Before the first isatuximab-irfc administration, conduct blood type and screen tests on isatuximab-treated patients. Consider phenotyping prior to starting isatuximab-irfc treatment. If treatment with isatuximab-irfc has already started, inform the blood bank that the patient is receiving isatuximab-irfc and isatuximab-irfc interference with blood compatibility testing can be resolved using dithiothreitol-treated RBCs. If an emergency transfusion is required, non–cross-matched ABO/RhD-compatible RBCs can be given as per local blood bank practices [see Drug Interactions (7.1) ] . Interference with Serum Protein Electrophoresis and Immunofixation Tests Isatuximab-irfc is an IgG kappa monoclonal antibody that can be incidentally detected on both serum protein electrophoresis and immunofixation assays (IFE) used for the clinical monitoring of endogenous M-protein. In patients with persistent very good partial response, where interference is suspected, consider using a validated isatuximab-specific IFE assay (Sebia Hydrashift) to remove isatuximab-irfc interference and specifically visualize any remaining serum M-protein, to facilitate determination of complete response. [see Drug Interactions (7.1) ] . 5.6 Embryo-Fetal Toxicity Based on its mechanism of action, isatuximab-irfc can cause fetal harm when administered to a pregnant woman. Isatuximab-irfc may cause fetal immune cell depletion and decreased bone density. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with isatuximab-irfc and for 7 months after the last dose [see Use in Specific Populations (8.1 , 8.3) ] . The combination of isatuximab-irfc with pomalidomide or lenalidomide is contraindicated in pregnant women because pomalidomide or lenalidomide may cause birth defects and death of the unborn child. Refer to the pomalidomide or lenalidomide prescribing information on use during pregnancy." ], "adverse_reactions": [ "6 ADVERSE REACTIONS The following clinically significant adverse reactions from SARCLISA ESCENA are also described in other sections of the labeling: Hypersensitivity and Other Administration Reactions [see Warnings and Precautions (5.1) ] Neutropenia [see Warnings and Precautions (5.2) ] Infections [see Warnings and Precautions (5.3) ] Second Primary Malignancies [see Warnings and Precautions (5.4) ] In combination with pomalidomide and dexamethasone : The most common adverse reactions (≥20%) are upper respiratory tract infection, fatigue, pneumonia, musculoskeletal pain, and diarrhea.

Interference with Serum Protein Electrophoresis and Immunofixation Tests Isatuximab-irfc may be incidentally detected by serum protein electrophoresis and immunofixation assays used for the monitoring of M-protein and may interfere with accurate response classification based on International Myeloma Working Group (IMWG) criteria [see Warnings and Precautions (5.5) ] . Because of this interference, Hydrashift assay was routinely used in IRAKLIA and IZALCO clinical studies for efficacy assessment to determine the complete response in patients with IgG kappa myeloma protein. In patients with persistent very good partial response, where interference is suspected, consider using an FDA-cleared isatuximab-irfc-specific IFE assay to distinguish isatuximab-irfc from any remaining endogenous M-protein in the patient's serum to facilitate determination of a complete response." ], "use_in_specific_populations": [ "8 USE IN SPECIFIC POPULATIONS Lactation : Advise not to breastfeed. ( 8.2 ) 8.1 Pregnancy Risk Summary Based on its mechanism of action [see Clinical Pharmacology (12.1) ] , SARCLISA ESCENA can cause fetal harm when administered to a pregnant woman. There are no available data on SARCLISA ESCENA use in pregnant women to evaluate for a drug-associated risk. The assessment of isatuximab-irfc-associated risks is based on its mechanism of action and data from target antigen CD38 knockout animal models (see Data ). No animal reproduction studies were conducted with isatuximab-irfc. Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The combination of SARCLISA ESCENA and pomalidomide or lenalidomide is contraindicated in pregnant women because pomalidomide and lenalidomide may cause birth defects and death of the unborn child. Refer to the pomalidomide or lenalidomide prescribing information on use during pregnancy. Pomalidomide and lenalidomide are only available through a REMS program. Clinical Considerations Fetal/neonatal adverse reactions Immunoglobulin G1 monoclonal antibodies are known to cross the placenta. Based on its mechanism of action, SARCLISA ESCENA may cause depletion of fetal CD38-positive immune cells and decreased bone density. Defer administration of live vaccines to neonates and infants exposed to SARCLISA ESCENA in utero until a hematology evaluation is completed. Data Animal data Mice that were genetically modified to eliminate all CD38 expression (CD38 knockout mice) had reduced bone density which recovered 5 months after birth. Data from studies using CD38 knockout animal models also suggest the involvement of CD38 in regulating humoral immune responses (mice), feto-maternal immune tolerance (mice), and early embryonic development (frogs). 8.2 Lactation Risk Summary There are no data on the presence of isatuximab-irfc in human milk or the effects on the breastfed child or milk production. Maternal immunoglobulin G is known to be present in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed child to SARCLISA ESCENA are unknown. Because of the potential for serious adverse reactions in a breastfed child, advise patients not to breastfeed during treatment with SARCLISA ESCENA and for 7 months after the last dose. 8.3 Females and Males of Reproductive Potential SARCLISA ESCENA can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Pregnancy Testing Verify the pregnancy status of females of reproductive potential prior to initiating SARCLISA ESCENA. With the combination of SARCLISA ESCENA with pomalidomide or lenalidomide, refer to the pomalidomide or lenalidomide labeling for pregnancy testing requirements prior to initiating treatment in females of reproductive potential. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with SARCLISA ESCENA and for 7 months after the last dose. Additionally, refer to the pomalidomide or lenalidomide labeling for contraception requirements prior to initiating treatment in females of reproductive potential. Males Refer to the pomalidomide or lenalidomide prescribing information. 8.4 Pediatric Use The safety and effectiveness of SARCLISA ESCENA in pediatric patients have not been established. 8.5 Geriatric Use Of the total number of patients in IRAKLIA, IZALCO, and IsaSoCut clinical studies of SARCLISA ESCENA (N=411), 38% (156 patients) were less than 65, 40% (166 patients) were 65–74, and 22% (89 patients) were 75 and over.

Isatuximab-irfc is produced from a mammalian cell line (Chinese hamster ovary, CHO) using a fed-batch production process. Isatuximab-irfc is composed of two identical immunoglobulin kappa light chains and two identical immunoglobulin gamma heavy chains and has an overall molecular weight of approximately 148 kDa. SARCLISA ESCENA (isatuximab-irfc) injection is a sterile, preservative-free, clear to slightly opalescent, colorless to slightly yellow solution, in a single-dose vial for subcutaneous use. Each vial contains 1,400 mg/10 mL at a concentration of 140 mg/mL with a pH of 6.2. Each mL of solution contains 140 mg isatuximab-irfc, arginine hydrochloride (23.2 mg), histidine (0.82 mg), histidine hydrochloride monohydrate (0.78 mg), poloxamer 188 (4.0 mg), sucrose (20.0 mg), and Water for Injection, USP." ], "clinical_pharmacology": [ "12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Isatuximab-irfc is an IgG1-derived monoclonal antibody that binds to CD38 expressed on the surface of hematopoietic and tumor cells, including multiple myeloma cells. Isatuximab-irfc induces apoptosis of tumor cells and activation of immune effector mechanisms including antibody-dependent cell-mediated cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), and complement dependent cytotoxicity (CDC). Isatuximab-irfc inhibits the ADP-ribosyl cyclase activity of CD38. Isatuximab-irfc can activate natural killer (NK) cells in the absence of CD38-positive target tumor cells and suppresses CD38-positive T-regulatory cells. The combination of isatuximab-irfc and pomalidomide enhanced ADCC activity and direct tumor cell killing compared to that of isatuximab-irfc alone in vitro, and enhanced antitumor activity compared to the activity of isatuximab-irfc or pomalidomide alone in a human multiple myeloma xenograft model. 12.2 Pharmacodynamics In multiple myeloma patients treated with SARCLISA ESCENA in combination with Pd, a decrease in CD38-positive NK cells was assessed and observed in bone marrow. Exposure-Response Relationship The exposure-response relationship and the time course of pharmacodynamics of subcutaneously administered isatuximab-irfc have not been fully characterized. Cardiac Electrophysiology Isatuximab-irfc as a large protein has a low likelihood of direct ion channel interactions. There is no evidence from non-clinical or clinical data to suggest that SARCLISA ESCENA subcutaneous dosage has the potential to delay ventricular repolarization. 12.3 Pharmacokinetics Isatuximab-irfc pharmacokinetics were characterized in patients with relapsed and/or refractory multiple myeloma in IRAKLIA study and are presented as mean (CV%) unless otherwise specified. Following the recommended dosage of SARCLISA ESCENA, the median time to reach steady state was 22 weeks (Cycle 6) with 4.9-fold accumulation for trough concentration (C trough ). The predicted maximum plasma concentration (C max ), C trough and area under the plasma concentration time curve (AUC 2weeks ) at steady state (Cycle 6) were 594 µg/mL (45.7%), 493 µg/mL (51.1%), and 188,000 µg.h/mL (47.3%), respectively. When comparing isatuximab-irfc exposures following the recommended SARCLISA ESCENA subcutaneous dosage to the recommended intravenous isatuximab-irfc dosage in Study IRAKLIA [see Clinical Studies (14) ] , the geometric mean ratios (GMRs) (90% CI) for observed steady state C trough (pre-dose at Cycle 6 day 1) was 1.53 (90% CI: 1.32–1.78). Absorption Following subcutaneous administration, isatuximab-irfc absolute bioavailability is 76% with a median time to reach maximum concentration (T max ) of approximately 4 days. Distribution The total volume of distribution of isatuximab-irfc is 5.53 (21.1%) L. Metabolism Isatuximab-irfc is expected to be metabolized into small peptides by catabolic pathways. Elimination Isatuximab-irfc is eliminated by two parallel pathways, a nonlinear target-mediated pathway predominating at low concentrations, and a nonspecific linear pathway predominating at higher concentrations. In the therapeutic plasma concentrations range, the linear pathway is largely predominant. Isatuximab-irfc linear clearance decreases over time by approximately 60% to a steady state value of 0.00479 (34.0%) L/h. The associated terminal half-life at steady state is 40.3 (30.8%) days. Specific Populations The following factors have no clinically meaningful effect on the exposure of isatuximab-irfc: age (31 to 86 years, 18% patients were ≥75 years old), sex, race (White 66%, Asian 15%), renal impairment including patients with End-Stage Renal Disease (ESRD) or on dialysis (eGFR <90 mL/min/1.73 m 2 ), and mild hepatic impairment (total bilirubin ≤ upper limit of normal [ULN] and aspartate aminotransferase [AST] >ULN, or total bilirubin >1 to 1.5 × ULN and any AST). The effect of moderate to severe hepatic impairment (total bilirubin >1.5 × ULN and any AST) on isatuximab-irfc pharmacokinetics is unknown. The effect of Black or African American (2.6%) race on the exposure of isatuximab-irfc is unknown. Body weight In patients who received the recommended SARCLISA ESCENA subcutaneous dosage, the steady state C trough and AUC 2weeks were 44% and 41% lower in the higher body weight (BW) group (>100 kg), and 24% and 26% higher in the lower BW group (≤50 kg), compared to the patients with BW of 51 kg–100 kg, respectively. The pharmacokinetics differences were not clinically meaningful across body weight categories. 12.6 Immunogenicity The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of isatuximab-irfc or of other isatuximab products. During treatment in 3 clinical studies (IRAKLIA, TCD15484, IZALCO) in relapsed and/or refractory multiple myeloma with SARCLISA ESCENA in combination therapies (up to 35 months), the incidence of treatment-emergent anti-drug antibodies (ADAs) was 4.9% (18/371) in patients evaluable for anti-drug antibodies. The incidence of treatment-emergent neutralizing antibodies in RRMM was 0.5% (2/371). During treatment in IsaSoCut clinical study in newly diagnosed multiple myeloma with SARCLISA ESCENA in combination with VRd (up to 11 months), the incidence of treatment-emergent ADAs was 15% (10/65) in patients evaluable for anti-drug antibodies. The incidence of treatment-emergent neutralizing antibodies in NDMM was 3.1% (2/65). There was no identified clinically significant effect of anti-isatuximab-irfc antibodies on pharmacokinetics of SARCLISA ESCENA.

The predicted maximum plasma concentration (C max ), C trough and area under the plasma concentration time curve (AUC 2weeks ) at steady state (Cycle 6) were 594 µg/mL (45.7%), 493 µg/mL (51.1%), and 188,000 µg.h/mL (47.3%), respectively. When comparing isatuximab-irfc exposures following the recommended SARCLISA ESCENA subcutaneous dosage to the recommended intravenous isatuximab-irfc dosage in Study IRAKLIA [see Clinical Studies (14) ] , the geometric mean ratios (GMRs) (90% CI) for observed steady state C trough (pre-dose at Cycle 6 day 1) was 1.53 (90% CI: 1.32–1.78). Absorption Following subcutaneous administration, isatuximab-irfc absolute bioavailability is 76% with a median time to reach maximum concentration (T max ) of approximately 4 days. Distribution The total volume of distribution of isatuximab-irfc is 5.53 (21.1%) L. Metabolism Isatuximab-irfc is expected to be metabolized into small peptides by catabolic pathways. Elimination Isatuximab-irfc is eliminated by two parallel pathways, a nonlinear target-mediated pathway predominating at low concentrations, and a nonspecific linear pathway predominating at higher concentrations. In the therapeutic plasma concentrations range, the linear pathway is largely predominant. Isatuximab-irfc linear clearance decreases over time by approximately 60% to a steady state value of 0.00479 (34.0%) L/h. The associated terminal half-life at steady state is 40.3 (30.8%) days. Specific Populations The following factors have no clinically meaningful effect on the exposure of isatuximab-irfc: age (31 to 86 years, 18% patients were ≥75 years old), sex, race (White 66%, Asian 15%), renal impairment including patients with End-Stage Renal Disease (ESRD) or on dialysis (eGFR <90 mL/min/1.73 m 2 ), and mild hepatic impairment (total bilirubin ≤ upper limit of normal [ULN] and aspartate aminotransferase [AST] >ULN, or total bilirubin >1 to 1.5 × ULN and any AST). The effect of moderate to severe hepatic impairment (total bilirubin >1.5 × ULN and any AST) on isatuximab-irfc pharmacokinetics is unknown. The effect of Black or African American (2.6%) race on the exposure of isatuximab-irfc is unknown. Body weight In patients who received the recommended SARCLISA ESCENA subcutaneous dosage, the steady state C trough and AUC 2weeks were 44% and 41% lower in the higher body weight (BW) group (>100 kg), and 24% and 26% higher in the lower BW group (≤50 kg), compared to the patients with BW of 51 kg–100 kg, respectively.

Patients had received at least one prior therapy including lenalidomide and a proteasome inhibitor. Patients were eligible for inclusion if they had an Eastern Cooperative Oncology Group (ECOG) status of 0–2, platelets ≥50,000 cells/mm 3 , absolute neutrophil count ≥1 × 10 9 /L, creatinine clearance ≥30 mL/min/1.73 m 2 (MDRD formula), AST ≤3 × ULN, and ALT ≤3 × ULN. Treatment was administered in both arms in 28-day cycles until disease progression or unacceptable toxicity. In both treatment arms, isatuximab-irfc was administered weekly in the first cycle and every two weeks thereafter. Pomalidomide 4 mg was taken orally once daily from day 1 to day 21 of each 28-day cycle. Dexamethasone orally 40 mg (20 mg for patients ≥75 years of age) was given on days 1, 8, 15, and 22 of each 28-day cycle. A total of 531 patients were randomized in a 1:1 ratio to receive either SARCLISA ESCENA 1,400 mg fixed dose as subcutaneous administration with OBDS device (SARCLISA ESCENA-Pd arm, 263 patients) or intravenous isatuximab-irfc as a 10 mg/kg intravenous infusion (intravenous isatuximab-irfc-Pd arm, 268 patients), in combination with pomalidomide and dexamethasone. The median patient age was 66 years (range 31–86), 18% of patients were ≥75 years; 69% of patients were White, 21% Asian, and 4.1% Black or African American. The International Staging System (ISS) stage at study entry was I in 59%, II in 27% and III in 12% of patients. Overall, 21% of patients had high-risk chromosomal abnormalities at study entry; del(17p), t(4;14), t(14;16), and chromosomal 1q21 abnormality. The median weight was 72 kg (range: 36 to 161), with 32% of patients with a weight ≤65 kg, 44% with a weight >65 kg to ≤85 kg, and 24% with a weight >85 kg. The median number of prior lines of therapy was 2 (range 1–8) and 30% of patients had received 1 prior line of therapy. All patients except 1 received a prior proteasome inhibitor and prior lenalidomide, and 56% of patients received prior stem cell transplantation. Patients were previously exposed to daratumumab, in 14% of patients in SARCLISA ESCENA-Pd arm vs 11% in intravenous isatuximab-irfc-Pd arm. The majority of patients (84%) were refractory to lenalidomide, 50% to a proteasome inhibitor, and 44% to both an immunomodulator and a proteasome inhibitor. The major efficacy measures were ORR as assessed by an Independent Review Committee, based on central laboratory data for M-protein and central radiologic imaging review using the International Myeloma Working Group (IMWG) criteria and the pharmacokinetic endpoint of C trough at steady state (corresponding to predose at Cycle 6 Day 1) [see Clinical Pharmacology (12.3) ]. The results show that SARCLISA ESCENA 1,400 mg administered subcutaneously in combination with Pd is non-inferior to intravenous isatuximab-irfc 10 mg/kg administered intravenously in combination with Pd in terms of ORR and C trough at steady state [see Clinical Pharmacology (12.3) ].
