What is Lemtrada?
Lemtrada is a prescription medicine used to treat relapsing forms of multiple sclerosis (MS), to include relapsing-remitting disease and active secondary progressive disease, in adults. Since treatment with Lemtrada can increase your risk of getting certain conditions and diseases, Lemtrada is generally prescribed for people who have tried 2 or more MS medicines that have not worked well enough. Lemtrada is not recommended for use in patients with clinically isolated syndrome (CIS).
It is not known if Lemtrada is safe and effective for use in children under 17 years of age.
Alemtuzumab is a recombinant humanized IgG1 kappa monoclonal antibody directed against the cell surface glycoprotein, CD52. Alemtuzumab has an approximate molecular weight of 150 kD. Alemtuzumab is produced in mammalian cell (Chinese hamster ovary) suspension culture in a nutrient medium containing neomycin. Neomycin is not detectable in the final product.
LEMTRADA (alemtuzumab) injection is a sterile, clear and colorless to slightly yellow, solution (pH 7.2 ± 0.2) for intravenous infusion.
Each 1 mL of solution contains 10 mg alemtuzumab, dibasic sodium phosphate (1.15 mg), disodium edetate dihydrate (0.0187 mg), polysorbate 80 (0.1 mg), potassium chloride (0.2 mg), potassium dihydrogen phosphate (0.2 mg), sodium chloride (8 mg), and Water for Injection, USP.
Mechanism of Action
The precise mechanism by which alemtuzumab exerts its therapeutic effects in multiple sclerosis is unknown but is presumed to involve binding to CD52, a cell surface antigen present on T and B lymphocytes, and on natural killer cells, monocytes, and macrophages. Following cell surface binding to T and B lymphocytes, alemtuzumab results in antibody-dependent cellular cytolysis and complement-mediated lysis.
What is the most important information I should know about Lemtrada?
Lemtrada can cause serious side effects, including:
1. Serious autoimmune problems. Some people receiving Lemtrada develop a condition where the immune cells in your body attack other cells or organs in the body (autoimmunity) which can be serious and may cause death. Serious autoimmune problems may include:
- immune thrombocytopenic purpura (ITP). Lemtrada may cause the number of platelets in your blood to be reduced (ITP). ITP can cause severe bleeding that may cause life-threatening problems. Call your healthcare provider right away if you have any of the following symptoms:
- easy bruising
- bleeding from a cut that is hard to stop
- coughing up blood
- heavier menstrual periods than normal
- bleeding from your gums or nose that is new or takes longer than usual to stop
- small, scattered spots on your skin that are red, pink, or purple
- kidney problems. Lemtrada may cause a serious kidney problem called anti-glomerular basement membrane disease. If this happens and you do not get treated, anti-glomerular basement membrane disease can lead to severe kidney damage, kidney failure that needs dialysis, a kidney transplant, or death. Call your healthcare provider right away if you have any of the following symptoms:
- swelling of your legs or feet
- blood in the urine (red or tea-colored urine)
- decrease in urine
- coughing up blood
Side effects may happen while you receive Lemtrada and for 4 years after you stop receiving Lemtrada. Your healthcare provider will order blood and urine tests before you receive, while you are receiving, and every month for 4 years after you receive your last Lemtrada infusion. You may need to continue these blood and urine tests after 4 years if you have any autoimmune signs or symptoms. The blood and urine tests will help your healthcare provider watch for signs and symptoms of serious autoimmune problems.
It is important to have your blood and urine tested, even if you are feeling well and do not have any symptoms from Lemtrada and your multiple sclerosis. This may help your healthcare provider find any problems early.
2. Serious infusion reactions. Lemtrada can cause serious infusion reactions that may cause death. Serious infusion reactions may happen while you receive, or up to 24 hours or longer after you receive Lemtrada.
You will receive your infusion at a healthcare facility with equipment and staff trained to manage infusion reactions. You will be watched while you receive and for at least 2 hours after you receive Lemtrada. It is important that you stay at the infusion center for at least 2 hours after your infusion is finished or longer if your healthcare provider decides you need to stay longer. If a serious infusion reaction happens while you are receiving Lemtrada, your infusion may be stopped.
Tell your healthcare provider right away if you have any of the following symptoms of a serious infusion reaction during the infusion, and after you have left the healthcare facility:
- swelling in your mouth or throat
- trouble breathing
- fast, slow, or irregular heartbeat
- chest pain
To lower your chances of getting a serious infusion reaction, your healthcare provider will give you a medicine called corticosteroids before your first 3 infusions of a treatment course. You may also be given other medicines before or after the infusion to try to reduce your chances of these reactions or to treat them after they happen.
3. Stroke and tears in your arteries that supply blood to your brain (carotid and vertebral arteries). Some people have had serious and sometimes deadly strokes and tears in their carotid or vertebral arteries within 3 days of receiving Lemtrada. Get help right away if you have any of the following symptoms that may be signs of a stroke or tears in your carotid or vertebral arteries:
- drooping of parts of your face
- sudden severe headache
- neck pain
- weakness on one side
- difficulty with speech
4. Certain cancers. Receiving Lemtrada may increase your chance of getting some kinds of cancers, including thyroid cancer, skin cancer (melanoma), and blood cancers called lymphoproliferative disorders and lymphoma. Call your healthcare provider if you have the following symptoms that may be a sign of thyroid cancer:
- new lump
- swelling in your neck
- pain in the front of your neck
- hoarseness or other voice changes that do not go away
- trouble swallowing or breathing
- cough that is not caused by a cold
You should have your skin checked before you start receiving Lemtrada and each year while you are receiving treatment to monitor symptoms of skin cancer.
Because of your risk of autoimmunity, infusion reactions, and the risk of some kinds of cancers, Lemtrada is only available through a restricted program called the Lemtrada Risk Evaluation and Mitigation Strategy (REMS) Program. Call 1-855-676-6326 to enroll in the Lemtrada REMS Program.
- You and your healthcare provider must be enrolled in the Lemtrada REMS Program.
- Lemtrada can only be given at a certified healthcare facility that participates in the Lemtrada REMS Program. Your healthcare provider can give you information on how to find a certified healthcare facility.
- Read the Lemtrada REMS “Lemtrada Treatment and Infusion Reactions Patient Guide” after you are enrolled in the program.
- Carry your Lemtrada REMS Patient Safety Information Card with you in case of an emergency.
