WELL-CHARACTERIZED SAFETY PROFILE

Your safety is important–so please make sure you review the following information carefully to educate yourself of the possible risks of MAVENCLAD. You should discuss all possible side effects with your healthcare provider.

MAVENCLAD safety has been extensively evaluated

About 24% of cladribine-treated patients in the clinical trial program were followed for up to 8 years. The mean time of the study follow-up was about 4.8 years. This helped to provide a clearer picture of the long-term safety of MAVENCLAD. These clinical trials evaluated the risk of side effects from MAVENCLAD. Keep in mind that the types and seriousness of side effects vary from patient to patient.

MAVENCLAD® has been extensively studied for fourteen years

It is not known if MAVENCLAD is safe and effective for people to restart MAVENCLAD treatment 2 years after completing their 2 yearly treatment courses.


Serious side effects

The types and seriousness of side effects vary from patient to patient. For a list of possible side effects and their symptoms, please see the Medication Guide. This is not intended to replace discussions with your healthcare provider. If you think you are experiencing any of these side effects or symptoms, please talk to your healthcare provider immediately.

Below are some of the possible serious side effects with MAVENCLAD.

CANCER (MALIGNANCIES)   

Treatment with MAVENCLAD may increase your risk of developing cancer. In clinical trials, cancers (malignancies) occurred more frequently in MAVENCLAD-treated patients than in those on placebo.

MAVENCLAD® vs. placebo

2.7 patients per year out of every 1000 patients taking MAVENCLAD could get a malignancy compared to 1.3 patients per year out of 1000 taking placebo.

PREGNANCY

MAVENCLAD may cause birth defects if used during pregnancy. Females must not be pregnant when they start treatment with MAVENCLAD or become pregnant during MAVENCLAD dosing and within 6 months after the last dose of each yearly treatment course.

LOW WHITE BLOOD CELL COUNT

Low blood cell counts have happened and can increase your risk of infections during your treatment with MAVENCLAD. Your healthcare provider will do blood tests before you start treatment with MAVENCLAD, during your treatment with MAVENCLAD, and afterward, as needed.

Icon indicating serious infection

SERIOUS INFECTIONS

Fatal cases of TB (1 case) and hepatitis (1 case) happened with cladribine during clinical studies. Patients also experienced other serious infections on MAVENCLAD, such as shingles (herpes zoster).

Icon indicating progressive multifocal leukoencephalopathy (PML)

PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY (PML)

PML is a rare brain infection that usually leads to death or severe disability. Although PML has not been seen in MS patients taking MAVENCLAD, it may happen in people with weakened immune systems. 

Icon indicating liver problems

LIVER PROBLEMS

MAVENCLAD may cause liver problems. Your healthcare provider should do blood tests to check your liver before you start taking MAVENCLAD.

Icon of a hand indicating allergic reaction

ALLERGIC REACTIONS (HYPERSENSITIVITIES)

MAVENCLAD can cause serious allergic reactions. Stop your treatment with MAVENCLAD and go to the closest emergency room for help right away if you have any signs or symptoms of allergic reactions. 

Heart icon indicating heart failure

HEART FAILURE

MAVENCLAD may cause heart failure, which means your heart may not pump as well as it should. Call your healthcare provider or go to the closest emergency room for medical help right away if you have any signs or symptoms such as shortness of breath, a fast or irregular heart beat, or unusual swelling in your body.


The most common side effects of MAVENCLAD

The most common side effects of MAVENCLAD® are upper respiratory infection, headache, and lymphopenia

WHAT IS MAVENCLAD?

MAVENCLAD 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.
