Long Term Study of Avonex Therapy Following a First Attack of Multiple Sclerosis - Full Text View

Purpose

The current study is an extension of the previous 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 continues to delay the development of further attacks and the development of neurological disability over a 10 year period of observation.

Arms

Assigned Interventions

Experimental: Immediate Treatment

Initiation of treatment with Interferon Beta 1a IM once weekly immediately after onset of a first demyelinating syndrome in high risk individuals

Drug: interferon beta 1a 30 ug IM once weekly

Immediate treatment group refers to those patients who were randomized to the interferon beta 1a 30 ug IM once weekly treatment arm of the original, controlled phase III CHAMPS study; Delayed treatment group refers to those patients who were randomized to the placebo group during the original controlled, phase III CHAMPS study and did not start treatment, if at all, until they completed the CHAMPS study protocol at a later date.

Active Comparator: Delayed Treatment

Delayed initiation of of Interferon beta-1a IM once weekly at diagnosis of clinically definite MS, at conclusion of initial CHAMPS study or during long term observation

Drug: interferon beta 1a 30 ug IM once weekly

Immediate treatment group refers to those patients who were randomized to the interferon beta 1a 30 ug IM once weekly treatment arm of the original, controlled phase III CHAMPS study; Delayed treatment group refers to those patients who were randomized to the placebo group during the original controlled, phase III CHAMPS study and did not start treatment, if at all, until they completed the CHAMPS study protocol at a later date.

Detailed Description:

The CHAMPS study determined that immediate initiation of interferon beta 1a therapy (AVONEX) immediately following a first clinical demyelinating event in high risk patients (i.e. those with at least 2 asymptomatic white matter lesions on cranial MR imaging > 3 mm in diameter or ovoid) delayed the development of clinical definite Multiple Sclerosis (CDMS)(as defined by a second, clinically verifiable attack involving another part of the central nervous system) over 2 years of observation and significantly decreased the development of new or enlarging white matter lesions on MRI over 18 months (see reference). The current study is a long term extension of a cohort of CHAMPS study participants. The three main aims of the study are as follows:

To determine the long term neurological outcome in patients treated with interferon beta 1a (AVONEX) from onset of a first clinical demyelinating event
To determine if immediate initiation of AVONEX therapy (the CHAMPS Avonex treatment group) confers long term benefits compared to delayed initiation of therapy (the CHAMPS placebo group) on the rate of development of CDMS, annualized relapse rates, the development of permanent disability and MR measures of disease activity and progression.
To determine predictors of long term disease activity and disability in patients following a first clinical demyelinating event
