Title: Controlled High-risk Avonex Multiple Sclerosis Prevention Study in Ongoing Neurologic Surveillance (CHAMPIONS10)
Brief Summary: The current study is a continuation of the 5 year extension study of the phase III CHAMPS study (see reference). This study was designed to determine if immediate initiation of therapy with Interferon Beta-1a (AVONEX) after a first attack of multiple sclerosis (MS) continues to delay the development of further attacks (CDMS) and the development of neurological disability over a 10 year period of observation. The initial 5 year extension study, called CHAMPIONS5, reported that immediate initiation of interferon Beta-1a (AVONEX) after a first attack of MS continued to delay the development of CDMS and lowered relapse rates compared to delayed initiation of disease modifying treatment (usually with AVONEX) either at the time of a second attack or at the end of the phase III study (24 months). The study was extended to 10 years to determine if these effects are sustained and result in less long term permanent disability.


Options:
A: Inclusion Criteria:

* Participation in a study site willing to participate in the CHAMPIONS10 extension study
* Willingness to enroll in the CHAMPIONS 10 extension
* Willingness to sign informed consent

Exclusion Criteria:

* Discovery of an alternative neurological disorder other than MS as a cause of initial neurological symptoms
* A severe systemic disease with likely mortality within 3 years
B: 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

Exclusion Criteria:

* Diagnosis of MS (per McDonald criteria 2005)
* Any other disease that could better explain the subject's signs and symptoms
* 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)
* Previously participated in this study
* Participated in any clinical trial within the past 6 months
* Any immunomodulatory or immunosuppressive therapy at any time prior to enrollment, including, but not limited to, the following products: any IFN, glatiramer acetate (Copolymer I), cyclophosphamide, cyclosporine, methotrexate, linomide, azathioprine, mitoxantrone, teriflunomide, laquinimod, cladribine, total lymphoid irradiation, anti-lymphocyte monoclonal antibody treatment (e.g. natalizumab, alemtuzumab/Campath, anti-cluster of differentiation 4 \[CD4\]), intravenous, immunoglobulins (Igs), cytokines or anti-cytokine therapy
* Any experimental MS treatment prior to trial entry, including, but not limited to, any statins (if given to prevent MS) and pentoxyfylline
* History of alcohol or drug abuse
* Intolerance or any contraindication to both paracetamol (acetaminophen) and ibuprofen
* Inability to administer subcutaneous injections either by self or by caregiver
* Moderate to severe renal impairment
C: Inclusion Criteria:

* Reach scheduled end of study in Study 27025 (REFLEX) (completion of 24 months participation)
* Medical assessment by the Investigator/treating physician from study 27025 that there is no objection to the subject's participation in this extension trial considering the medical experience from Study 27025 (REFLEX). Special attention should be given to laboratory abnormalities and clinically significant liver, renal and bone-marrow dysfunction
* 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 vasectomized partner
* Subject is willing to follow study procedures
* Subject has given written informed consent

Exclusion Criteria:

* Subject has any disease other than MS that could better explain the subject's signs and symptoms
* Subject has a primary progressive course of MS
* Subject has total bilirubin greater than 2.5 times upper limit of normal (ULN) at both Month 24 and at the previous visit (i.e. Month 21) (subjects with greater than 2.5 times ULN at Month 24 only are eligible for enrollment and should be managed as per label recommendations until normalization of the value)
* Subject has total aspartate aminotransferase (AST) or alanine aminotransferase (ALT) or alkaline phosphatase (ALP) greater than 2.5 times the ULN values at both Month 24 and at the previous visit (i.e. Month 21) (subjects with greater than 2.5 times ULN at Month 24 only are eligible for enrollment and should be managed as per label recommendations until normalization of the value)
* Subject suffers from another current autoimmune disease
* Subject suffers from 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
