Trial Outcomes & Findings for Extension Study of BG00012 in Pediatric Subjects With Relapsing Remitting Multiple Sclerosis (RRMS) (NCT NCT02555215)

NCT ID: NCT02555215

Last Updated: 2019-11-22

Results Overview

An AE is any untoward medical occurrence that does not necessarily have a causal relationship with treatment. An SAE is any untoward medical occurrence that at any dose: results in death; in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; results in a congenital anomaly/birth defect; any other medically important event that, in the opinion of the Investigator, may jeopardize the participant or may require intervention to prevent one of the other outcomes listed in the definition above.

PRIMARY outcome

Timeframe: Baseline to Week 96

Population: The safety population was defined as all participants who received at least 1 dose of BG00012.

An AE is any untoward medical occurrence that does not necessarily have a causal relationship with treatment. An SAE is any untoward medical occurrence that at any dose: results in death; in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; results in a congenital anomaly/birth defect; any other medically important event that, in the opinion of the Investigator, may jeopardize the participant or may require intervention to prevent one of the other outcomes listed in the definition above.

SECONDARY outcome

Timeframe: Baseline to Week 96

Population: Participants who received at least 1 dose of BG00012 in this study and had an evaluation of the efficacy endpoint under analysis.

Relapses were defined as new or recurrent neurologic symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings upon examination by the Investigator. New or recurrent neurologic symptoms that evolved gradually over months were considered disability progression, not an acute relapse, and were not treated with steroids. The ARR was calculated as the total number of relapses that occurred during the previous 12 months and during the 120 weeks on treatment for participants in Study 109MS202 that continued into Study 109MS311, divided by the total number of person-years followed prior to the study and by the total number of person-years followed during the study, respectively.

Population: Participants who received at least 1 dose of BG00012 in this study and had an evaluation of the efficacy endpoint under analysis.

The Expanded Disability Status Scale (EDSS) measures disability status on a scale ranging from 0 to 10, with higher scores indicating more disability. Scoring is based on measures of impairment in eight functional systems on examination by a neurologist.
