LA JOLLA, Calif., Feb. 28, 2019 (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 Scientific Reports has published results from the animal model study evaluating MN-166 (ibudilast) in glioblastoma (GBM). The article, “Ibudilast sensitizes glioblastoma to temozolomide by targeting Macrophage Migration Inhibitory Factor (MIF),” is the first publication reporting the potential clinical utility of MN-166 (ibudilast) for GBM.
Key findings in this publication include the following: (1) In an in-vitro study using patient derived cell lines, MN-166 (ibudilast) combined with temozolomide (TMZ) showed significant synergism in cell cycle arrest and apoptosis, and (2) In an in-vivo patient derived xenograft (PDX) model study, combination treatment with MN-166 (ibudilast) and TMZ resulted in significantly longer overall survival.
“Earlier studies indicate that macrophage migration inhibitory factor (MIF) and phosphodiesterase (PDE)-4 may factor in proliferation of GBM tumors. MIF was found to be highly expressed within GBM cells, and especially around necrotic areas and in close proximity to blood vessels. MN-166 (ibudilast) in combination with TMZ resulted in significant blockage of MIF expression, increased apoptosis, and longer survival in vivo,” commented Kerrie McDonald, Ph.D., Associate Professor, University of New South Wales, Australia, the study’s lead researcher.
Yuichi Iwaki, M.D., Ph.D., President and Chief Executive Officer of MediciNova, Inc., commented, “We are very pleased that these findings were published in Scientific Reports. These findings compelled us to open an IND application and evaluate MN-166 (ibudilast) in a clinical trial of patients with GBM. Enrollment is ongoing at Dana-Farber Cancer Institute.”
About the Glioblastoma Clinical Trial
This Phase 1/2 clinical trial is divided into a dose-escalation phase (Part 1) followed by a fixed-dose phase (Part 2). A total of 15-18 adult subjects are planned to be enrolled in Part 1 and approximately 32 subjects are planned to be enrolled in Part 2. Part 1 will evaluate the safety and tolerability of MN-166 (ibudilast) when given in combination with TMZ, and determine the dose of MN-166 (ibudilast) to be used in Part 2 of the study. Part 2 will evaluate the efficacy of MN-166 (ibudilast) and temozolomide combination treatment in patients with recurrent GBM as measured by the proportion of patients who are progression-free at 6 months. Other outcome measures include the evaluation of overall survival, response rate, and median six-month progression-free survival.
According to the American Association of Neurological Surgeons, GBM is a devastating brain cancer that typically results in death in the first 15 months after diagnosis. GBM develops from glial cells (astrocytes and oligodendrocytes) and rapidly grows and commonly spreads into nearby brain tissue. GBM is classified as Grade IV, the highest grade, in the World Health Organization (WHO) brain tumor grading system. The American Brain Tumor Association reports that GBM represents 15% of all brain tumors and 56% of all gliomas and has the highest number of cases of all malignant tumors, with approximately 12,000 new cases diagnosed each year. Despite decades of advancements in neuroimaging, neurosurgery, chemotherapy, and radiation therapy, only modest improvements have been achieved and the prognosis has not improved for individuals diagnosed with GBM. Median survival is 14.6 months and two-year survival is 30%. Approximately 5% of GBM patients survive longer than 36 months.
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. It 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 progressive multiple sclerosis (MS) and other neurological diseases such as amyotrophic lateral sclerosis (ALS), glioblastoma (GBM), and substance abuse/addiction. MediciNova is developing MN-166 for progressive MS and other neurological conditions such as ALS, glioblastoma, substance abuse/addiction, and chemotherapy-induced neuropathy. MediciNova has a portfolio of patents which covers the use of MN-166 (ibudilast) to treat various diseases including progressive MS, ALS, and drug addiction.
MediciNova, Inc. is a publicly-traded biopharmaceutical company founded upon developing novel, small-molecule therapeutics for the treatment of diseases with unmet medical needs with a primary commercial focus on the U.S. market. MediciNova's current strategy is to focus on MN-166 (ibudilast) for neurological disorders such as progressive multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), glioblastoma (GBM), and substance dependence (e.g., alcohol use disorder, methamphetamine dependence, opioid dependence), and MN-001 (tipelukast) for fibrotic diseases such as nonalcoholic steatohepatitis (NASH) and idiopathic pulmonary fibrosis (IPF). MediciNova’s pipeline also includes MN-221 (bedoradrine) and MN-029 (denibulin). For more information on MediciNova, Inc., please visit www.medicinova.com.
