Inclusion Criteria

· Subject with a single, first clinical event suggestive of MS within 60 days prior to SD1, which is the day of randomisation (clock starts 24 hours after onset). The event must be a new neurological abnormality present for at least 24 hours, either mono- or polysymptomatic, other than a paresthesia, vegetative or cerebral dysfunction;
· Subject has at least two clinically silent lesions on the T2-weighted MRI scan, with a size of at least 3 mm, at least one of which is ovoid or periventricular or infratentorial;
· EDSS 0 - 5.0 at at least one time point during the screening period before start of treatment;
· Subject is between 18 and 50 years old, inclusive;
· Subject is willing to follow study procedures;
· Subject has given written informed consent;
· If female, subject must:
a) be neither pregnant nor breast-feeding nor attempting to conceive
b) use a highly effective method of contraception. A highly effective method of contraception is defined as those which result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly such as implants, injectables, combined oral contraceptives, some IUDs, sexual abstinence or vasectomised partner.*

*Note for subjects using a hormonal contraceptive method: No formal drug interaction studies have been carried out with IFN-beta-1a or HSA free IFN beta 1a. As interferons have been reported to exert an inhibitory activity on hepatic microsomal enzymes, it is unlikely that the clearance of oral contraceptives would be increased and result in decreased efficacy. In over 10,000 patient-years of clinical trial experience with Rebif®, there has never been any indication of an interaction with oral contraceptives.
