Description of intervention(s) / exposure
Treatment: Drugs - RNF
Treatment: Drugs - RNF
Treatment: Drugs - Placebo

Active comparator: RNF 44 mcg three times weekly -

Active comparator: RNF 44 mcg once weekly and placebo twice weekly for blinding -

Placebo comparator: Placebo three times weekly -


Treatment: Drugs: RNF
Single dose of RNF administered subcutaneously three times weekly at least 48 hours apart at a starting dose of 8.8 microgram (mcg) for first 2 weeks followed by 22 mcg for next 2 weeks and finally 44 mcg until 24 months, or 36 months for patients enrolled in the OL extension.

Treatment: Drugs: RNF
Single dose of RNF administered subcutaneously once weekly at a starting dose of 8.8 mcg for first 2 weeks followed by 22 mcg for next 2 weeks and finally 44 mcg until 24 months.

Treatment: Drugs: Placebo
Placebo was supplied as a transparent, sterile solution for injection in pre-filled syringes matching the RNF pre-filled syringes, each containing 0.5 mL.

Eligibility
Key inclusion criteria
* Single, first clinical event suggestive of MS within 60 days prior to study Day 1, which is the day of randomization (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
* At least two clinically silent lesions on the T2-weighted MRI scan, with a size of at least 3 millimeter (mm), at least one of which is ovoid or periventricular or infratentorial
* EDSS 0 - 5.0 at least one time point during the screening period before start of treatment
* 18 and 50 years old, inclusive
* Willing to follow study procedures
* Written informed consent
* If female, subject must:

* be neither pregnant nor breast-feeding nor attempting to conceive
* use a highly effective method of contraception. A highly effective method of contraception is defined as those which result in a low failure rate (that is [i.e.] less than 1 percent [%] per year) when used consistently and correctly such as implants, injectables, combined oral contraceptives, some intrauterine devices (IUDs), sexual abstinence or vasectomised partner
Minimum age
18 Years
Maximum age
50 Years
Sex
Both males and females
Can healthy volunteers participate?

* Complete transverse myelitis or bilateral optic neuritis
* Subject uses or has used any other approved MS disease-modifying drug (DMD)
* Any investigational drug or undergone an experimental procedure within 12 weeks prior to study Day 1
* Oral or systemic corticosteroids or adrenocorticotropic hormone (ACTH) within 30 days prior to study Day 1
* Total bilirubin greater than 2.5 times upper limit of normal (ULN)
* Subject has total aspartate aminotransferase (AST) or alanine aminotransferase (ALT) or alkaline phosphatase (ALP) greater than 2.5 times the ULN
* Inadequate bone marrow reserve, defined as a total white blood cell count less than 3.0 x 109 per liter (/L), platelet count less than 75 x 109/L, hemoglobin less than 100 gram per liter (g/L)
* Current autoimmune disease
* Major medical or psychiatric illness (including history of or current severe depressive disorders and/or suicidal ideation) that in the opinion of the investigator creates undue risk to the subject or could affect compliance with the study protocol
* History of seizures not adequately controlled by treatment
* Cardiac disease, such as angina, congestive heart failure or arrhythmia
* Known allergy to IFN-beta or the excipient(s) of the study medication
* Any condition that could interfere with the MRI evaluation;
* Known allergy to gadolinium-diethylene triamine pentaacetic acid (DTPA)
