About CARE-MS II

The content of this website relates only to U.S. recruitment.

CARE-MS II is seeking 1,200 adults worldwide.

To be eligible for CARE-MS II, potential participants must meet specific criteria that includes, among others:

  • Diagnosis: RRMS
  • Therapy: Have already been treated for RRMS
  • Age: 18 - 55
  • MS Symptoms: Experienced symptoms while on approved MS therapy within the last 10 years
  • Every patient in the CARE-MS studies will receive active treatment; there is no placebo.

Participation in the CARE-MS trials may offer participants the opportunity to help advance research in the treatment of MS while taking a role in their healthcare.

One alemtuzumab treatment cycle will be administered intravenously each year for 2 years. Participants will receive alemtuzumab daily for the first 5 days of the first year and daily for the first 3 days of the second year. Rebif® will be given by injection under the skin 3 times per week throughout both years of the study period. Rebif can be self-administered or administered by a caregiver.

In CARE-MS II, there is a 4-in-5 chance that participants will receive alemtuzumab, and a 1-in-5 chance that participants will receive Rebif.

Study Duration
CARE-MS II study participants will be involved for 2 years. Participants receiving alemtuzumab will be followed in an extension study for safety for at least 3 years after their last dose. Participants may be asked to take part in neurological evaluations to determine if any lasting treatment benefits exist. At the completion of the 2-year study, participants receiving Rebif may be eligible to receive alemtuzumab in an extension study.

Participation is completely voluntary. Study participants may withdraw at any time.
