Official title

Controlled High-risk Avonex Multiple Sclerosis Prevention Study in Ongoing Neurologic Surveillance (CHAMPIONS10)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
