NCT01982942

Brief Summary

This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study designed to evaluate the safety, tolerability and activity of ibudilast administered twice daily over a 96 week period in subjects with primary or secondary progressive multiple sclerosis who are currently untreated with long-term MS disease modifying therapy (DMT) or who are receiving either glatiramer acetate (GA) or interferon beta-1, any formulation (IFNβ-1A \[Avonex, Rebif\] or IFNβ-1B \[Betaseron, Extavia\]). Study drug or placebo will be administered to a total of 250 male and female subjects from 21 to 65 years old, inclusive, in two treatment groups. Randomization of subjects will be stratified by disease status (primary progressive multiple sclerosis or secondary progressive multiple sclerosis) and immunomodulating therapy status: current use of immunomodulating therapy or no current use of immunomodulating therapy. The study will consist of a screening phase (up to 30 days) followed by a treatment phase (96 weeks) and a follow-up visit (1 month post Week 96 visit). Following the screening phase, subjects who continue to meet entry criteria will be randomly assigned to 1 of 2 treatment groups: doses up to ibudilast 100 mg/day or matching-placebo in a 1:1 ratio. Study drug will be administered twice daily (BID), e.g., ibudilast 50 mg or placebo taken in the morning and evening).

Outcome Measures

Primary Outcomes (2)

  • Covariate-adjusted Mean Rate of Change in Brain Atrophy Over 96 Weeks as Measured by Brain Parenchymal Fraction (BPF).

    To evaluate the activity of ibudilast (100 mg/day) versus placebo at 96 weeks as measured by quantitative magnetic resonance imaging (MRI) analysis for whole brain atrophy using brain parenchymal fraction (BPF), calculated as the ratio of brain parenchymal tissue volume to the total volume contained within the brain surface contour.

    96 weeks

  • Percentage of Participants With Adverse Events.

    Safety Measures: percentage of participants who experienced treatment-emergent adverse events, clinically significant abnormal laboratory and electrocardiogram results.

    96 weeks

Secondary Outcomes (3)

  • Diffusion Tensor Imaging (DTI) in Descending Pyramidal White Matter Tracts

    48 weeks

  • Magnetization Transfer Ratio (MTR) Imaging in Normal-appearing Brain Tissue

    96 weeks

  • Retinal Nerve Fiber Layer as Measured by Optical Coherence Tomography (OCT).

    96 weeks

Other Outcomes (1)
