BG00012 Monotherapy Safety and Efficacy Extension Study in Multiple Sclerosis (MS) (ENDORSE)

This study is ongoing, but not recruiting participants.
Sponsor:
Information provided by (Responsible Party):
Biogen
ClinicalTrials.gov Identifier:
NCT00835770
First received: February 2, 2009
Last updated: May 4, 2017
Last verified: May 2017
  Purpose
The primary objective of this study is to evaluate the long-term safety profile of BG00012 (dimethyl fumarate). Secondary objectives of this study are to evaluate the long-term efficacy of BG00012 using clinical endpoints and disability progression, to evaluate further the long-term effects of BG00012 on multiple sclerosis (MS) brain lesions on magnetic resonance imaging (MRI) scans in participants who had MRI scans as part of Studies 109MS301 (NCT00420212) and 109MS302 (NCT00451451) and to evaluate the long-term effects of BG00012 on health economics assessments and the visual function test.

Condition Intervention Phase
Relapsing-Remitting Multiple Sclerosis Drug: dimethyl fumarate Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Participant, Outcomes Assessor
Primary Purpose: Treatment
Official Title: A Dose-Blind, Multicenter, Extension Study to Determine the Long-Term Safety and Efficacy of Two Doses of BG00012 Monotherapy in Subjects With Relapsing-Remitting Multiple Sclerosis

Primary Outcome Measures:
  • Number of Participants with Adverse Events [ Time Frame: Day 1 up to 12 years ]

Secondary Outcome Measures:
  • Number of Participants Who Had Relapses [ Time Frame: Day 1 up to 12 years ]
  • Annualized Relapse Rate (ARR) [ Time Frame: Day 1 up to 12 years ]
  • Change from Baseline in the Expanded Disability Status Scale (EDSS) up to 12 years [ Time Frame: Day 1 up to 12 years ]
    Progression of disability is defined as at least a 1.0 point increase on the EDSS from baseline EDSS 1.0 that is sustained for 24 weeks or at least a 1.5 point increase on the EDSS from baseline EDSS =0 that is sustained for 24 weeks. The 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.

  • Number and volume of Gd-enhancing lesions as Measured by Magnetic Resonance Imaging (MRI) [ Time Frame: Day 1 up to 12 years ]
  • Number and volume of new or newly-enlarging T2 lesions as Measured by Magnetic Resonance Imaging (MRI) [ Time Frame: Day 1 up to 12 years ]
  • Number and volume of T1 hypointense lesions [ Time Frame: Day 1 to 12 years ]
  • Change from Baseline in Brain atrophy up to 12 years [ Time Frame: Day 1 to 12 years ]
  • Summary of Magnetization Transfer Ratio (MTR) [ Time Frame: Day 1 to 12 years ]
    MTR is used in neuroradiology to highlight abnormalities in brain structures

  • Change from Baseline in EQ-5D Health Survey (EQ-5D) up to 12 years [ Time Frame: Day 1 to 12 years ]
    EQ-5D is a self-administered questionnaire consisting of 5 sets of 3 questions pertaining to specific health states (i.e., mobility, self-care, pain, usual activities, anxiety), a health status rating scale, and demographic questions.

  • Change from baseline in SF-36® Health Survey (SF-36) up to 12 years [ Time Frame: Day 1 to 12 years ]
    The SF-36 is a self-administered, generic health status questionnaire consisting of 36 questions that measure 8 health concepts: physical functioning, role limitations due to physical problems, bodily pain, general health perception, vitality, social functioning, role limitations due to emotional problems and mental health.

  • Change from Baseline in Visual Function test scores up to 12 years [ Time Frame: Day 1 to 12 years ]

Estimated Primary Completion Date: February 6, 2023 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: BG00012 plus placebo
In the first phase, participants will receive BG00012 240 mg (two 120 mg capsules) twice a day (BID) and 2 placebo capsules once a day. In the second phase participants will receive open-label BG00012 240 mg BID, for up to 12 years.
Drug: dimethyl fumarate
BG00012 capsules
Other Names:
  • BG00012
  • Tecfidera
  • DMF
Drug: Placebo
Capsules taken to maintain the blind in the 240 mg BID treatment group.
Experimental: BG00012
In the first phase participants will receive BG00012 240 mg (two 120 mg capsules) three times a day (TID). In the second phase participants will receive open-label BG00012 240 mg BID for up to 12 years.
Drug: dimethyl fumarate
BG00012 capsules
Other Names:
  • BG00012
  • Tecfidera
  • DMF

Detailed Description:
The initial BG00012 dosage for the extension study (240 mg BID or 240 mg TID) was the same as that used in the Phase 3 Studies 109MS301 (NCT00420212) and 109MS302 (NCT00451451). Subsequent to the initiation of this study, BG00012 was approved in several countries for the treatment of MS at a dose of 240 mg BID. For this reason, all participants continuing in this study will receive the currently marketed dose of 240 mg BID.
