Lemtrada (alemtuzumab) is an anti-CD52 monoclonal antibody. It's used to treat relapsing forms of multiple sclerosis (MS) in adults, but only when other MS medications haven't worked well. Lemtrada (alemtuzumab) is given as an infusion through the veins once per year by a healthcare provider. Since this medication has many risks and side effects, it's only available through a Risk Evaluation and Mitigation Strategy (REMS) program) called the Lemtrada REMS program. Some common side effects of Lemtrada (alemtuzumab) include rash, headache, and fever.
People with multiple sclerosis (MS) have an immune system that attacks their own nervous system, such as the brain and spinal cord.
Lemtrada (alemtuzumab) is a CD52 monoclonal antibody. The exact way it treats MS isn't well-understood. But it's thought to dampen the immune system by attaching to a protein called CD52 found on certain immune cells. This temporarily lowers the amount of immune cells in the body, which can lessen inflammation and bring relief of MS symptoms.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.

Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:
More common
Fear or nervousness
Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.
Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
In a 2-year clinical study, 65% of people who took Lemtrada (alemtuzumab) had no MS relapses. This is compared to about 50% of people who took Rebif (interferon beta-1a) (another MS medication). Talk with your provider if you have more questions about how well Lemtrada (alemtuzumab) works.
Lemtrada (alemtuzumab) is given as an infusion into the veins (IV). The typical length of the infusion is 4 hours. But, your provider might slow the infusion if you get any infusion-related reactions.
It takes over 2 months for most of Lemtrada (alemtuzumab) to leave your body after a single dose. This time frame is estimated based on the half-life of Lemtrada (alemtuzumab). If you're able to become pregnant, you still need to use effective birth control for 4 months after your last dose of Lemtrada (alemtuzumab) as a precaution. If you have more questions about how long Lemtrada (alemtuzumab) stays in your body, talk with your provider.
No, Lemtrada (alemtuzumab) isn't a chemotherapy. Chemotherapy is a type of treatment that kills all fast-growing cells and is typically used to treat cancer. Instead, Lemtrada (alemtuzumab) is a monoclonal antibody that treats MS by specifically targeting immune cells. Please note that alemtuzumab goes by another brand name (Campath) that's FDA-approved to treat a certain type of blood cancer. Like Lemtrada, Campath is a monoclonal antibody.
No, Lemtrada (alemtuzumab) doesn't cure MS; it only treats the symptoms of MS. Currently, there isn't a cure for MS available on the market.
Both Ocrevus (ocrelizumab) and Lemtrada (alemtuzumab) are monoclonal antibodies that treat MS. One major difference is Ocrevus (ocrelizumab) can be used to treat all forms of MS, whereas Lemtrada (alemtuzumab) is only used to treat relapsing forms of MS (e.g., relapsing-remitting MS, secondary progressive MS). Secondly, Lemtrada (alemtuzumab) tends to have more side effects than Ocrevus (ocrelizumab), so it's typically used in people who don't respond well to at least two other MS medications. Thirdly, rounds of Lemtrada (alemtuzumab) infusions are given a year apart. But Ocrevus (ocrelizumab) is generally given every 6 months.
Lemtrada (alemtuzumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Lemtrada (alemtuzumab) is linked to many serious side effects, including autoimmune problems, infusion reactions, stroke, and cancers. Because of these risks, it's only available through a restricted Risk Evaluation and Mitigation Strategy (REMS) program called the Lemtrada REMS program. All providers who prescribe Lemtrada (alemtuzumab), pharmacies that dispense the medication, and people who need to use the injection must be registered with the REMS program. This program helps to make sure you and your providers are all aware of the risks with Lemtrada (alemtuzumab), and that you're familiar with the symptoms of serious health problems and know when it's time to get medical help.
Lemtrada (alemtuzumab) can cause your body to make antibodies. These antibodies can attack different parts of your body, which can cause serious and life-threatening problems. As a precaution, your provider will regularly monitor your labs and organ health during and for 4 years or longer after your last dose of Lemtrada (alemtuzumab).
Some specific examples of autoimmune problems seen in people taking Lemtrada (alemtuzumab) include:
Contact your provider immediately if you notice any of these symptoms.
It's possible for you to get severe allergic and infusion reactions with Lemtrada (alemtuzumab). These reactions typically happen within 3 days of your infusion. To lower your risk for these reactions, your provider will have you take corticosteroids for the first 3 days of each treatment course. Your provider will also monitor you for at least 2 hours after the Lemtrada (alemtuzumab) infusion to make sure you're not experiencing any symptoms. If you do experience symptoms of an allergic or infusion-related reaction such as swelling in the mouth or throat, trouble breathing, weakness, rash, or chest pain, get medical help right away.
Lemtrada (alemtuzumab) can raise your risk of getting a stroke. This is most likely to happen within 3 days of receiving Lemtrada (alemtuzumab). Call 911 if you experience symptoms of stroke, such as sudden neck or face pain, trouble speaking, droopy face, sudden confusion, or numbness or weakness in the face, arm, or leg.
Lemtrada (alemtuzumab) can raise your risk of certain cancers, such as thyroid cancer and skin cancer. Contact your provider if you notice signs of thyroid cancer, such as any new lumps or swelling in your neck, pain in the front of the neck, changes in your voice, trouble swallowing or breathing, constant cough not due to an infection, or changes in your skin.
Make sure you also schedule yearly screenings for skin cancer and let your provider know if you notice changes to your skin.
Lemtrada (alemtuzumab) can cause several types of inflammatory problems. Specific examples of inflammatory problems seen in people taking Lemtrada (alemtuzumab) include:
Contact your provider right away if you notice any of these symptoms.
Lemtrada (alemtuzumab) can affect your body's ability to fight off infections, which can raise your risk of serious bacterial (e.g., Listeria, tuberculosis (TB)), viral (e.g., herpes, hepatitis, human papilloma virus (HPV)), or fungal infections. Your provider will routinely monitor you for infections before and during treatment with Lemtrada (alemtuzumab) and might give you antimicrobial medications to prevent or treat the infection(s).
To lower your risk for Listeria (a bacteria that grows in raw, undercooked, or unpasteurized foods) infection, make sure to review which types of foods can potentially have Listeria. If you get an infection, you might have to stop taking Lemtrada (alemtuzumab) so your body can fight it off. Get medical help right away if you have fever, cough, difficulty breathing, diarrhea, weakness, sweating, or chills while taking Lemtrada (alemtuzumab).
A full treatment with Lemtrada (alemtuzumab) includes 2 treatment courses, given a year apart.
If needed, your provider might have you continue with additional treatment courses of Lemtrada (alemtuzumab). Each additional course can be given 1 year after your last course. The typical dose is 12 mg infused IV once daily for 3 days.
