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.

How LEMTRADA was studied

LEMTRADA was studied in two 2-year clinical trials against Rebif® (interferon beta-1a) 44 mcg. Patients were treated with LEMTRADA for 2 years and were then invited to continue in an Extension Study for an additional 4 years, for a total of 6 years in the studies.

There were 628 people in the 2-year study (Study 1), with 426 taking LEMTRADA and 202 taking Rebif. 9 out of 10 people (387) who took LEMTRADA entered the Study 1 Extension, with most (332) continuing through 4 years.

During an Infusion

LEMTRADA infusion information
  • You will receive your infusions at a healthcare facility with equipment and staff trained to manage infusion reactions.
  • Before, during, or after your infusion begins, you will be given certain medications to help reduce the chance of having a serious infusion reaction or to treat them if they happen.
  • It will take approximately 4 hours to receive 1 dose of LEMTRADA. The time may vary based on a number of factors.
 
Duration of infusions and post-infusion monitoring
  • You will be monitored closely during the infusion and for at least 2 hours following the completion of the infusion to watch for any infusion reactions.
  • You can expect to be at the infusion facility for up to 8 hours or more per day.
  • LEMTRADA can cause serious side effects during infusion or up to 24 hours or longer after you receive LEMTRADA. Tell your healthcare provider immediately if you experience any discomfort during or after your infusion.

Monthly monitoring

Monthly monitoring to detect potential side effects starts after your first infusion and continues until 4 years or longer after the last round of treatment. You will need:

  • monthly blood and urine tests
  • self-checks
  • yearly skin checks

These help to monitor for possible side effects that can show up months or even years after your last infusion, including:

  • autoimmune side effects
  • some kinds of cancers including skin cancer (melanoma)

It is important to have your blood and urine tested, even if you are feeling well and do no have any symptoms from LEMTRADA or your MS. This may help your healthcare provider find side effects early.
