Important safety information

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…
