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).

Eligibility Criteria
You may qualify if:
- Written informed consent is obtained and willing and able to comply with the protocol in the opinion of the Investigator.
- Male or female subjects ages 21 to 65, inclusive
- Confirmed diagnosis of SPMS or primary progressive multiple sclerosis (PPMS) according to 2010 International Panel Criteria

- EDSS 3.0-6.5, inclusive
- Clinical evidence of disability progression in the preceding two years, as measured by any of the following (excluding progression during clinical relapses):
- worsening overall EDSS of at least 0.5 points (may be assessed retrospectively but cannot be during a clinical relapse) or
- % worsening in 25-foot walk (25-FW) or
- % worsening in 9-hole peg test (9-HPT) in either hand
- Existing multiple sclerosis pharmacotherapy status may include interferon-beta or glatiramer acetate or none (i.e. untreated).
- Females of child-bearing potential must have a negative serum ß-hCG at screening and must be willing to use appropriate contraception (as defined by the investigator) for the duration of study treatment and 30 days after the last dose of study treatment.
- Males should practice contraception as follows: condom use and contraception by female partner.
- Subject is in good physical health on the basis of medical history, physical examination, and laboratory screening, as defined by the investigator.
- Subject is willing and able to comply with the protocol assessments and visits, in the opinion of the study nurse/coordinator and the Investigator.
You may not qualify if:
- Progressive neurological disorder other than SPMS or PPMS
- Relapse and/or systemic corticosteroid steroid treatment for multiple sclerosis within 3 months of screening. Inhaled or topical steroids are allowed.
- Current use of intermittent systemic corticosteroids (i.e., monthly or bimonthly intravenous methylprednisolone)
- Use of oral immunosuppressants (e.g. azathioprine, methotrexate, cyclosporine, teriflunomide \[Aubagio®\]) within 6 months of screening
- Use of mitoxantrone, natalizumab, or IVIg within 6 months of screening
- Use of fingolimod or dimethyl fumarate \[Tecfidera®\] within 3 months of screening
- Use of rituximab or other B-cell therapy within 12 months of screening
- Current use of other MS disease-modifying therapies (DMTs) besides glatiramer acetate, IFNβ-1 (any formulation), and the above listed medications.
- Current use of cimetidine, cyclosporine, dronedarone, lopinavir, probenecid, quinidine (including Neudexta), ranolazine, rifampin, ritonavir, or tipranavir.
- Clinically significant cardiovascular disease, including myocardial infarct within last 6 months, unstable ischemic heart disease, congestive heart failure or angina
- Resting pulse \< 50 bpm, sinoatrial (SA) or atrioventricular (AV) block, uncontrolled hypertension, or QTcF \> 450 ms
