Approval: Rebif (EMA)
Indication: Rebif is indicated for the treatment of: patients with a single demyelinating event with an active inflammatory process, if alternative diagnoses have been excluded, and if theyShow full indication

Rebif is indicated for the treatment of: patients with a single demyelinating event with an active inflammatory process, if alternative diagnoses have been excluded, and if they are determined to be at high risk of developing clinically definite multiple sclerosis; patients with relapsing multiple sclerosis. In clinical trials, this was characterised by two or more acute exacerbations in the previous two years. Efficacy has not been demonstrated in patients with secondary progressive multiple sclerosis without ongoing relapse activity.

Approval: Avonex (EMA)
Indication: Avonex is indicated for the treatment of: patients diagnosed with relapsing multiple sclerosis (MS). In clinical trials, this was characterised by two or more acute exacerbationsShow full indication

Avonex is indicated for the treatment of: patients diagnosed with relapsing multiple sclerosis (MS). In clinical trials, this was characterised by two or more acute exacerbations (relapses) in the previous three years without evidence of continuous progression between relapses; Avonex slows the progression of disability and decreases the frequency of relapses; patients with a single demyelinating event with an active inflammatory process, if it is severe enough to warrant treatment with intravenous corticosteroids, if alternative diagnoses have been excluded, and if they are determined to be at high risk of developing clinically definite MS. Avonex should be discontinued in patients who develop progressive MS.
