Isatuximab is a chimeric monoclonal antibody targeted against surface CD38 glycoproteins for the treatment of multiple myeloma in patients who have failed previous therapies.
Isatuximab (formerly SAR650984) is a humanized, IgG1-derived monoclonal antibody (mAb) produced from a Chinese hamster ovary (CHO) cell line. Structurally, isatuximab is comprised of two identical immunoglobulin kappa light chains and two identical immunoglobulin gamma heavy chains. It is a cytolytic antibody targeted against CD38, a glycoprotein found on the surface of some immune cells that is highly expressed by malignant plasma cells in multiple myeloma.[rx]Along with daratumumab, another anti-CD38 mAb, isatuximab constitutes a novel treatment modality for patients with difficult-to-treat multiple myeloma.
Following three consecutive years on the yearly “Antibodies to watch” list published in “mAb”, a peer-reviewed scientific journal dedicated to antibody research, isatuximab was granted Orphan Drug designation and approved on March 2nd, 2020, for the treatment of multiple myeloma. It is manufactured by Sanofi-Aventis U.S. under the brand name Sarclisa.[rx]
Mechanism of action
Multiple myeloma is a blood cancer characterized by an overproduction of malignant plasma cells in the bone marrow. A unique characteristic of myeloma cells is their dense and uniform expression of CD38 surface glycoproteins – these proteins, also expressed in relatively minor quantities on other lymphoid and myeloid cells, have been identified as performing several critical cellular functions, and this, along with their relative abundance on myeloma cells, has made them an attractive target for multiple myeloma treatment. CD38 was first identified as an activation marker, but has subsequently demonstrated roles in adhesion to endothelial CD31 proteins, as an accessory component of the synapse complex, and as an ectoenzyme involved in the metabolism of extracellular NAD+ and cytoplasmic NADP. The products of CD38’s ectoenzymatic activity include the calcium-mobilizing compound adenosine diphosphate ribose (ADPR), which can be further metabolized by CD203a/PC-1 and CD73 to adenosine, an immunosuppressive molecule that may play a role in tumor cell evasion of the immune system.[rx]
Isatuximab is an IgG1-derived monoclonal antibody targeted against CD38 proteins.[rx] Its activity against CD38 results in a number of downstream effects, including direct apoptosis of the affected cell and activation of immune mechanisms including antibody-dependent cell-mediated cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), and complement-dependent cytotoxicity (CDC), all of which result in potent anti-tumor activity.[rx] Via allosteric antagonism, isatuximab also inhibits CD38 ectoenzymatic activity, preventing the immunosuppressive effects of its downstream products.
Isatuximab may also exert its effects via downstream promotion of lysosome-dependent cell death, upregulation of reactive oxygen species, and restoration of antitumor immune effector cell functions.[rx]
Isatuximab results in the apoptosis of malignant plasma cells via inhibition of a surface protein key to their survival and proliferation. It has a relatively long residence time in the body, taking approximately 2 months to clear following the final dose, and may therefore be infused on a weekly or bimonthly schedule.[rx] Isatuximab is given in combination with pomalidomide due to a synergy that exists between the two – isatuximab can induce a depletion in host NK lymphocytes, yet the ADCC effect of anti-CD38 mAbs has been shown to be superior in patient samples with a high ratio of NK to myeloma cells. Pomalidomide, another antineoplastic agent, has the ability to induce and enhance NK lymphocyte activity[rx]and thus works synergistically to enhance isatuximab-mediated killing of myeloma cells.[rx]
Isatuximab is formulated as an intravenous infusion and its administration may result in infusion-related reactions characterized most commonly by dyspnea, cough, chills, and nausea. All noted reactions started during the first infusion and 98% resolved on the same day. Reactions may be mitigated by pre-medication with acetaminophen, H2 antagonists, diphenhydramine, and/or dexamethasone.[rx] Patients with grade 1 or 2 reactions may restart the infusion at a slower rate following the resolution of symptoms, but patients experiencing a grade 3 or higher reaction (e.g. hypertension, bronchospasm) should discontinue therapy indefinitely.[rx]
Isatuximab can generate false positive results for indirect antiglobulin tests (indirect Coombs tests), immunofixation tests, and serum protein electrophoresis.[rx]

Pregnancy and Lactation
FDA Pregnancy Category C
Pregnancy
SARCLISA can cause fetal harm when administered to a pregnant woman. The assessment of rituximab-erfc-associated risks is based on the mechanism of action and data from target antigen CD38 knockout animal models (see Data). 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. Animal reproduction toxicity studies have not been conducted with isatuximab-irfc. The estimated background risk of major birth defects and
miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defects, miscarriages, 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. The combination of SARCLISA and pomalidomide is contraindicated in pregnant women because pomalidomide may cause birth defects and the death of the unborn child. Refer to the pomalidomide prescribing information on use during pregnancy. Pomalidomide is only available through a REMS program.
Lactation
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. Refer to pomalidomide prescribing information for additional information.
Why is this medication prescribed?
Isatuximab-irfc injection is used along with pomalidomide (Pomalyst) and dexamethasone to treat multiple myeloma (a type of cancer of the bone marrow) in adults who have received at least two other medications, including lenalidomide (Revlimid) and a proteasome inhibitor such as bortezomib (Velcade) or carfilzomib (Kyprolis). It is also used along with carfilzomib (Kyprolis) and dexamethasone to treat multiple myeloma in adults whose cancer has returned or is unresponsive to at least one other treatment. Isatuximab-irfc injection is in a class of medications called monoclonal antibodies. It works by helping the body to slow or stop the growth of cancer cells.
How should this medicine be used?
Isatuximab-irfc injection comes as a solution (liquid) to be injected intravenously (into a vein) by a doctor or nurse. Initially, it is usually given on days 1, 8, 15, and 22 of the first 28-day cycle. After the first cycle, it is usually given on days 1 and 15 of 28-day cycle. This cycle may be repeated as long as the medication continues to work and does not cause severe side effects.
A doctor or nurse will watch you closely while you are receiving the infusion and after the infusion to be sure you are not having a serious reaction to the medication. You will be given other medications to help prevent reactions to isatuximab-irfc. Tell your doctor or nurse immediately if you experience any of the following symptoms that may occur during the infusion or for up to 24 hours after you receive the infusion: nausea; shortness of breath; wheezing; difficulty breathing; swelling of the face, mouth, throat, or tongue; throat tightness; dizziness; lightheadedness; fainting; runny or stuffy nose; nasal congestion; cough; or chills.
Your doctor may permanently or temporarily stop your treatment. This depends on how well the medication works for you and the side effects you experience. Be sure to tell your doctor how you are feeling during your treatment with isatuximab-irfc. Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient. This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
What special precautions should I follow?
