About Copay AssistanceSarclisa is a brand-name medication. It contains the active drug isatuximab-irfc, a member of a family of medicines called monoclonal antibodies (mAbs). Monoclonal antibodies are lab-created proteins that modify your immune response to specific diseases, including cancer.
What Is Sarclisa Used To Treat?
Isatuximab-irfc injection is used with pomalidomide (Pomalyst) and dexamethasone to treat multiple myeloma in adults previously treated with at least two other medicines, including lenalidomide and a proteasome inhibitor (e.g., bortezomib).
A doctor may prescribe this medication with carfilzomib and dexamethasone to treat recurring or treatment-resistant multiple myeloma in adults who did not benefit from one to three prior therapies.
How Does Sarclisa Work?
Isatuximab-irfc kills cancer cells directly (by inducing programmed cell death) or by activating your immune cells to destroy cancer cells.
How Is Sarclisa Supplied and Used?
Sarclisa injection is available as a sterile, colorless to slightly yellow liquid in a single-dose vial. Each vial contains 100 mg/5 ml or 500 mg/25 ml of the active drug.
A doctor or nurse will administer Sarclisa by intravenous (IV) infusion into your vein. Treatment comprises two or more cycles of 28 days (4 weeks).
In the first cycle, you will receive the drug weekly (on days 1, 8, 15, and 22). In the subsequent cycles, Sarclisa is administered every two weeks (on days 1 and 15).
A doctor or nurse will monitor you closely during and after the infusion to see if you develop infusion reactions. To reduce the risk of infusion reactions, your doctor will give you specific medicines about one hour before each dose of Sarclisa, including:
- Allergy medications
- Medicine to reduce pain and fever
- A steroid
Before starting treatment, inform your doctor if you:
- Have heart problems
- Are pregnant or plan to become pregnant
- Are nursing a child
- Have had shingles (herpes zoster)

Decreased white blood cell (WBC) count
Sarclisa can cause a low WBC count. In some users, certain WBCs can be severely decreased. WBCs help your body fight infection. Thus, low WBC counts can make you more likely to get certain infections, such as upper and lower respiratory tract infections and urinary tract infections.
Talk to your doctor immediately if you develop fever or other signs of infection during treatment, such as:
- Chills and sweats
- Change in cough or a new cough
- Sore throat or new mouth sore
- Shortness of breath
