Question: Is ibudilast effective for multiple sclerosis?

Context: Ibudilast slowed brain atrophy in PPMS and SPMS patients in a multicenter phase 2b study.
Ibudilast inhibits several cyclic nucleotide phosphodiesterases, macrophage migration inhibitory factor, and toll-like receptor 4 and can cross the blood-brain barrier, with potential salutary effects in progressive multiple sclerosis.
CONCLUSIONS: In a phase 2 trial involving patients with progressive multiple sclerosis, ibudilast was associated with slower progression of brain atrophy than placebo but was associated with higher rates of gastrointestinal side effects, headache, and depression.
Specifically, the current evidence regarding treatment of progressive MS with ocrelizumab, simvastatin, ibudilast, alpha-lipoic acid, high-dose biotin, siponimod, and cell-based therapies are discussed.
Based on our knowledge of pathophysiology, three therapeutic strategies are proposed: anti-inflammatory (ocrelizumab, siponimod…); remyelinating (opicinumab); and neuroprotective (high-dose biotin, ibudilast, simvastatin…).
Current article provides an overview of the pharmacology of IBD with a focus on preclinical and clinical data supporting its potential neuroprotective benefits for neurological conditions, including multiple sclerosis, neuropathic pain, medication overuse headache, stroke, opioid, alcohol and methamphetamine abuse.
Design, rationale, and baseline characteristics of the randomized double-blind phase II clinical trial of ibudilast in progressive multiple sclerosis.
METHODS: SPRINT-MS is a randomized, placebo-controlled, phase II trial of ibudilast in patients with PMS.
CONCLUSION: SPRINT-MS is designed to evaluate the safety and efficacy of ibudilast as a treatment for PMS while simultaneously validating five different imaging biomarkers as outcome metrics for use in future phase II proof-of-concept PMS trials.
Ibudilast for the treatment of multiple sclerosis.
AREAS COVERED: This article reviews various studies looking at ibudilast as a potential therapy for MS. It summarizes prior and current clinical trials of ibudilast in MS as well as its pharmacology.EXPERT OPINION: Although ibudilast has not been found to decrease the focal inflammatory activity in relapsing MS, it was shown to have an effect on preserving brain volume and disability progression. Ibudilast may have a role in the treatment of progressive MS phenotypes.
