Indications

BETASERON® (interferon beta-1b) is a prescription medicine used to treat relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.

      PROVEN to significantly delay time to a second flare-up in patients with CIS

      In a 2-year study, 292 patients with clinically isolated syndrome* who started treatment early with BETASERON significantly reduced their likelihood of having a second flare-up compared with 176 patients on placebo

      *Patients included in the BENEFIT Study experienced a first neurological event suggestive of multiple sclerosis, which is also referred to as clinically isolated
      syndrome. Patients also had at least 2 lesions on a T2-weighted brain MRI scan that did not cause any symptoms.

      PROVEN to reduce the number of newly active brain lesions in patients with CIS

      MRI data from a 2-year study showed that BETASERON patients with the first symptoms of MS had fewer newly active lesions at 2 years

      IMPORTANT SAFETY INFORMATION (CONT'D)

      BETASERON can cause serious side effects, including:

      Liver Problems Including Liver Failure. Symptoms of liver problems may include yellowing of your eyes, itchy skin, feeling very tired, flu-like symptoms, nausea or vomiting, bruising easily or bleeding problems. Your healthcare provider will do blood tests to check for these problems while you take BETASERON.

      Please see additional Important Safety Information below.

      PROVEN to cut frequency of flare-ups in patients with RRMS

      In a 2-year study, 124 patients taking BETASERON had 31% fewer relapses than 123 patients taking placebo

      The second main result showed the proportion of patients who had not had a flare-up at 2 years did not significantly differ between the placebo (16%) and BETASERON (25%) treatment groups

      §All patients were ambulatory with EDSS scores of 5.5 or less and had at least 2 acute exacerbations during the previous 2 years.

      IMPORTANT SAFETY INFORMATION (CONT'D)

      BETASERON can cause serious side effects, including:

      Serious Allergic Reactions. Serious allergic reactions can happen quickly and may happen after your first dose of BETASERON or after you have taken BETASERON many times. Symptoms may include difficulty breathing or swallowing, swelling of the mouth or tongue, rash, itching, or skin bumps.
