WARNINGS AND PRECAUTIONS

• Infusion-Related Reactions:                                                                                   Interrupt SARCLISA and manage medically. Permanently discontinue for grade =3 reactions. 

• Neutropenia:                                                                                                        Monitor complete blood cell counts periodically during treatment. Monitor patients with neutropenia for signs of infection. SARCLISA dose delays and the use of colony-stimulating factor may be required to allow improvement of neutrophil count.

 • Second Primary Malignancies (SPM):                                                               Monitor patients for the development of second primary malignancies, as per IMWG guidelines.

 • Laboratory Test Interference:                                                                                    o Interference with Serological Testing (Indirect Antiglobulin Test): Type and screen patients prior to starting treatment. Inform blood banks that a patient has received SARCLISA.

 o Interference with Serum Protein Electrophoresis and Immunofixation Tests: SARCLISA may interfere with the assays used to monitor Mprotein, which may impact the determination of complete response.

 • Embryo-Fetal Toxicity:                                                                                             Can cause fetal harm.

 CLINICAL PHARMACOLOGY

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.

2. Pharmacodynamics-                                                                                                In multiple myeloma patients treated with SARCLISA combined with pomalidomide and dexamethasone, a decrease in absolute counts of total NK cells (including inflammatory CD16+ low CD56+ bright and cytotoxic CD16+ bright CD56+ dim NK cells) and CD19+ B cells was observed in peripheral blood.

Cardiac Electrophysiology-                                                                                            Up to 2 times the approved recommended dose, SARCLISA does not prolong the QT interval to any clinically relevant extent. 

A relationship between isatuximab-irfc exposure and overall response rate and progression-free survival was observed. No apparent relationship was observed between an increase of isatuximab-irfc exposure and adverse reactions.

3. Pharmacokinetics-                                                                                              Following the administration of isatuximab-irfc at the recommended dose and schedule, the steady state isatuximab-irfc mean (CV %) predicted maximum plasma concentration (Cmax) was 351 µg/mL (36.0%) and area under the plasma concentration-time curve (AUC) was 72,600 µg·h/mL (51.7%). 

Distribution-                                                                                                               The mean (CV %) predicted total volume of distribution of isatuximab-irfc is of 8.13 L (26.2%). Metabolism Isatuximab-irfc is expected to be metabolized into small peptides by catabolic pathways.

Elimination-                                                                                                     Isatuximab-irfc total clearance decreased with increasing dose and with multiple doses. At steady state, the near elimination (=99%) of isatuximab-irfc from plasma after the last dose is predicted to occur in approximately 2 months.   

The elimination of isatuximab-irfc was similar when given as a single agent or as combination therapy.

Specific Populations                                                                                              Isatuximab-irfc exposure (AUC) at steady state decreases with increasing body weight.

The following factors have no clinically meaningful effect on the exposure of isatuximab-irfc: age (36 to 85 years, 70 patients were >75 years old), sex, race (Caucasian, Black, Asian), renal impairment (eGFR<90 mL/min/1.73 m2 ), and mild hepatic impairment (total bilirubin 1 to 1.5 times upper limit of normal [ULN] or aspartate amino transferase [AST] > ULN).

The effect of moderate (total bilirubin >1.5 times to 3 times ULN and any AST) and severe (total bilirubin >3 times ULN and any AST) hepatic impairment on isatuximab-irfc pharmacokinetics is unknown. No dose adjustments are recommended in these specific patient populations.

 USE IN SPECIFIC POPULATIONS

1. Pregnancy Risk Summary                                                                                   SARCLISA can cause fetal harm when administered to a pregnant woman.

There are no available data on SARCLISA use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. 

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.

All pregnancies have a background risk of birth defect, miscarriage, 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% to 4% and 15% to 20%, respectively.

2. Lactation Risk Summary

There are no available data on the presence of isatuximab-irfc in human milk, milk production, or the effects on the breastfed child. Maternal immunoglobulin G is known to be present in human milk.

The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed infant to SARCLISA are unknown.

Because of the potential for serious adverse reactions in the breastfed child from isatuximab-irfc administered in combination with pomalidomide and dexamethasone, advise lactating women not to breastfeed during treatment with SARCLISA.

3 Females and Males of Reproductive Potential Pregnancy Testing-                   With the combination of SARCLISA with pomalidomide, refer to the pomalidomide labeling for pregnancy testing requirements prior to initiating treatment in females of reproductive potential.

Contraception Females- SARCLISA can cause fetal harm when administered to a pregnant woman 

Advise female patients of reproductive potential to use effective contraception during treatment and for at least 5 months after the last dose of SARCLISA.

Additionally, refer to the pomalidomide labeling for contraception requirements prior to initiating treatment in females of reproductive potential. Males Refer to the pomalidomide prescribing information.

4. Pediatric Use Safety and effectiveness in pediatric patients have not been established.

5 Geriatric Use-                                                                                                            Of the total number of subjects in clinical studies of SARCLISA, 53% (306 patients) were 65 and over, while 14% (82 patients) were 75 and over.

No overall differences in safety or effectiveness were observed between subjects 65 and over and younger subjects, and other reported clinical experience has not identified differences in responses between the adults 10 years and over and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

OVERDOSE

There is no known specific antidote for SARCLISA overdose. In the event of overdose of SARCLISA, monitor the patients for signs or symptoms of adverse effects and take all appropriate measures immediately.
