Studies evaluating the use of Mavenclad (generic name: cladribine) for multiple sclerosis (MS) found a reduction in MS relapses (flare-ups) over about a two year period. A relapse is a period of time when MS symptoms get worse.

  • Over 96 weeks, 81% of patients who took Mavenclad were relapse-free compared to 63% of those who took a placebo.
  • Mavenclad also decreased 3-month progression of disability (worsening) due to MS when compared to a placebo.
  • It also significantly reduced the median number of MRI lesions when compared to a placebo at 96 weeks.

In the clinical trial program of Mavenclad in MS, the mean time in the study (including follow-up) was almost 5 years, and roughly one-quarter of patients who received treatment had 8 years of time in the study, including follow-up.

Mavenclad works over the long-term, but for most patients, the active ingredient in Mavenclad does not remain in the body beyond one week after administration. However, long-term safety concerns exist with Mavenclad, and you should discuss these with your doctor before starting treatment.
