| Measure | Time frame |
|---|---|
| Main Objective: How many multiple slerosis patients show a reduction of the neutralizing antibodies < 100 neutralizing units after 3 months of weekly intravenous interferon-beta infusion. ;Secondary Objective: What is the absolute reduction of the neutralizing antibody titre after 3 months of weekly intravenous interferon-beta infusion and after 3 further months. Do lesions show a reduced MR-activity after the end of the interferon-beta infusions. Does activity of peripheral blood mononuclear cells change over the study period.;Primary end point(s): Non-respond of MxA RNA, a biomarker for interferon-beta bioavailability, after 2 infusions of 48 MIU interferon-beta. The last follow up after 6 months. | — |
