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.
In patients with clinically isolated syndrome (CIS), BETASERON® was PROVEN to
In patients with relapsing-remitting multiple sclerosis (RRMS), BETASERON was PROVEN to
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
BETASERON cut risk of a second flare-up in half
Likelihood of a second flare-up within 2 years:
*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.
†By proportional hazard ratio regression adjusted for age/gender/steroids/T2 lesions/Gd lesions.
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
BETASERON reduced the number of brain lesions
fewer newly active lesions‡
Newly active brain lesions:
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
BETASERON cut the frequency of

It's important to know the possible risks and benefits of BETASERON. Make sure you talk to your doctor to understand which possible side effects are more serious than others, as well as those that are more common.Learn more about safety
