MediciNova, Inc., a biopharmaceutical company traded on the NASDAQ Global Market (NASDAQ:MNOV) and the Standard Market of the Tokyo Stock Exchange (Code Number: 4875), today announced that MediciNova's collaborator, Justin Lathia PhD, Co-Director of the Brain Tumor Research and Therapeutic Development Center of Excellence at Cleveland Clinic Lerner Research Institute, and Professor, Department of Molecular Medicine at Cleveland Clinic Lerner College of Medicine of Case Western Reserve University, and Patrick Wen, Director at the Center for Neuro-Oncology at Dana-Farber Cancer Institute, Professor of Neurology, Harvard Medical School, presented new data and results of a Phase 2 clinical trial of MN-166 (ibudilast) in glioblastoma (GBM) patients at the 28th Annual Meeting of the Society for Neuro-Oncology (SNO) held November 15 - 19, 2023 in Vancouver, Canada. The presentation also included data from preclinical studies which evaluated the combination of MN-166 (ibudilast) and anti-PD1 or anti-PD-L1 therapy in GBM models.
The primary endpoints of this Phase 2 clinical trial were safety and tolerability of MN-166 (ibudilast) and temozolomide (TMZ) combination treatment and efficacy of the combination treatment defined as progression-free survival rate at 6 months using the RANO criteria. MN-166 (ibudilast) and TMZ combination treatment was safe and well-tolerated, and no unexpected adverse effects were reported.
The highlights of the presentation are as follows:
Phase II clinical trial and immunohistochemistry study
Preclinical GBM model studies
Kazuko Matsuda, M.D., Ph.D., M.P.H., Chief Medical Officer of MediciNova, Inc., commented, "We are very pleased to report the positive safety and efficacy results from the first GBM clinical trial of MN-166. GBM's rapid progression and resistance to therapy poses a serious challenge to the medical community. Evaluation of MN-166 (ibudilast) as an adjuvant therapy with TMZ in GBM patients was generally safe and well tolerated. For the PFS6 primary efficacy endpoint, recurrent GBM patients showed a higher PFS6 rate compared to most historical studies. Moreover, the preclinical studies presented at this meeting support our postulation that adding MN-166 (ibudilast) to existing therapies, e.g., TMZ, anti-PD1 or anti-PD-L1, improves survival more than the individual therapies alone. We are excited by the findings presented by our esteemed collaborators and look forward to completing the full data analysis from the GBM clinical trial. We are eager to evaluate MN-166 (ibudilast) in combination with anti-PD1 and anti-PD-L1 therapies in a future clinical trial. MediciNova is grateful to the patients and families for their invaluable participation in our trial."
About MN-166 (ibudilast)
MN-166 (ibudilast) is a small molecule compound that inhibits phosphodiesterase type-4 (PDE4) and inflammatory cytokines, including macrophage migration inhibitory factor (MIF). It is in late-stage clinical development for the treatment of neurodegenerative diseases such as ALS (amyotrophic lateral sclerosis), progressive MS (multiple sclerosis), and DCM (degenerative cervical myelopathy); and is also in development for glioblastoma, Long COVID, CIPN (chemotherapy-induced peripheral neuropathy), and substance use disorder. In addition, MN-166 (ibudilast) was evaluated in patients that are at risk for developing acute respiratory distress syndrome (ARDS).
