MediciNova Announces Positive Optical Coherence Tomography Results from the SPRINT-MS Phase 2b Trial of MN-166 (ibudilast) in Progressive MS Published…

LA JOLLA, Calif., Nov. 25, 2020 (GLOBE NEWSWIRE) -- MediciNova, Inc., a biopharmaceutical company traded on the NASDAQ Global Market (NASDAQ:MNOV) and the JASDAQ Market of the Tokyo Stock Exchange (Code Number: 4875), today announced that positive Optical Coherence Tomography (OCT) results from the SPRINT-MS Phase 2b trial of MN-166 (ibudilast) in progressive multiple sclerosis (progressive MS) were published in Multiple Sclerosis Journal. OCT was a secondary outcome measure in the SPRINT-MS trial.

The publication, entitled Optical coherence tomography outcomes from SPRINT-MS, a multicenter, randomized, double-blind trial of ibudilast in progressive multiple sclerosis, is a report of the OCT results of the SPRINT-MS trial. The authors include Robert A. Bermel and Robert J. Fox, both from the Mellen Center for Multiple Sclerosis Treatment and Research at the Cleveland Clinic, and several others. The authors conclude that retinal thinning in MS may be attenuated by MN-166 (ibudilast) and that sample size estimates suggest OCT can be a viable outcome measure in progressive MS trials if a therapy has a large treatment effect.

Of the 28 sites participating in the SPRINT-MS trial, 22 sites used Zeiss Cirrus OCT and 6 sites used Heidelberg Spectralis OCT. This resulted in 183 participants imaged with Cirrus and 61 participants imaged with Spectralis.

All OCT measures showed less loss of retinal tissue for MN-166 (ibudilast) compared to placebo. Key results reported in the publication include the following:

Yuichi Iwaki, MD, PhD, President and Chief Executive Officer of MediciNova, Inc. commented, We are very pleased that the positive OCT data has been published. This data demonstrates that MN-166 can reduce retinal thinning in progressive MS patients and is further evidence of its neuroprotective effect as retinal thinning is associated with brain volume loss and other measures of MS progression.

About the Progressive MS Trial

The Phase 2b Secondary and Primary Progressive Ibudilast NeuroNEXT trial in Multiple Sclerosis (SPRINT-MS) included 28 enrolling clinical sites across the U.S. and was designed to evaluate the safety, tolerability and activity of MN-166 (ibudilast) administered orally twice daily to subjects with primary progressive or secondary progressive multiple sclerosis (PPMS or SPMS, respectively). 255 qualifying subjects were randomly assigned 1:1 to inactive control (placebo) or MN-166 (ibudilast) administered at a dose of up to 100 mg/day (50 mg twice daily). The progressive MS subjects were either untreated with long-term disease modifying therapy (DMT) or continued on either glatiramer acetate (GA) or interferon beta (IFN-1a or IFN-1b) treatment. Hence, randomization was controlled (stratified) by two factors: therapy status (IFN/GA vs. no DMT) and disease status (PPMS vs. SPMS). The primary objectives of the study were to 1) evaluate the activity of ibudilast (MN-166) versus placebo at 96 weeks as measured by quantitative magnetic resonance imaging (MRI) analysis for whole brain atrophy using brain parenchymal fraction (BPF), and 2) evaluate the safety and tolerability of ibudilast (MN-166) versus placebo in subjects with PPMS or SPMS. Additional measures included disability, imaging analyses of brain and retinal tissue integrity, cortical atrophy, cognitive impairment, quality-of-life and neuropathic pain. Exploratory objectives included pharmacokinetic and biomarker analyses.

About the Cooperative Effort

The collaborating entities included NeuroNEXT, theCleveland Clinic, theNational MS SocietyandMediciNova.NINDS's Network for Excellencein Neuroscience Clinical Trials, or NeuroNEXT, was created to conduct studies of treatments for neurological diseases through partnerships with academia, private foundations and industry. NeuroNEXT sites include many of the leading medical centers in the U.S. (www.neuronext.org). The goals of NeuroNEXT include testing of promising neurological therapies in Phase 2 clinical trials, optimizing drug development time and cost components through an established clinical trials infrastructure, and the coordination of public/private sector efforts by leveraging NINDSs existing relationships with academic investigators and patient advocacy groups. A clinical coordinating center for NeuroNEXT was led by Dr. Merit Cudkowicz and was based atMassachusetts General Hospitaland the data coordinating center was led by Dr.Chris Coffeyat theUniversity of Iowa. Principal Investigator Dr.Robert Foxand colleagues at theCleveland Cliniccollaborated with co-investigators at academic medical centers in the NeuroNEXT network.The National MS Societyprovided patient advocate input, trial enrollment awareness, and additional funding.MediciNovaholds the trial IND with the FDAsDivision of Neurology Productsand provided scientific and analytical support, as well as drug and placebo supply.

About Progressive Multiple Sclerosis

According to theNational MS Society, MS affects approximately 2.3 million people worldwide. Approximately 85% of MS patients are initially diagnosed with relapsing remitting MS (RRMS). Many RRMS patients will eventually transition into secondary progressive MS (SPMS) in which there are fewer or no relapses but gradual worsening of neurologic function. Approximately 15% of MS patients are diagnosed with primary progressive MS (PPMS) at onset and exhibit gradually increasing disability in walking, vision, mental acuity, and other bodily functions without experiencing relapses or remissions. Current therapies for MS affect the inflammatory response, but provide limited benefit for the neurodegeneration seen in progressive MS. There is a significant unmet medical need for agents that may provide neuroprotection in progressive MS.

About MN-166 (ibudilast)

MN-166 (ibudilast) is a first-in-class, orally bioavailable, small molecule macrophage migration inhibitory factor (MIF) inhibitor and phosphodiesterase (PDE) -4 and -10 inhibitor that suppresses pro-inflammatory cytokines and promotes neurotrophic factors. Our earlier human studies demonstrated significant reductions of serum MIF level after treatment with MN-166 (ibudilast). It also attenuates activated glial cells, which play a major role in certain neurological conditions. MN-166 (ibudilast)'s anti-neuroinflammatory and neuroprotective actions have been demonstrated in preclinical and clinical studies, which provide the rationale for treatment of amyotrophic lateral sclerosis (ALS), progressive multiple sclerosis (MS) and other neurological diseases such as glioblastoma (GBM), and substance abuse/addiction. MediciNova is developing MN-166 for ALS, progressive MS and other neurological conditions such as degenerative cervical myelopathy (DCM), glioblastoma, substance abuse/addiction, and chemotherapy-induced peripheral neuropathy, as well as prevention of acute respiratory distress syndrome (ARDS) caused by COVID-19. MediciNova has a portfolio of patents which covers the use of MN-166 (ibudilast) to treat various diseases including ALS, progressive MS, and drug addiction.
