MediciNova, in Collaboration with the University of Sydney and the Australasian Gastro-Intestinal Trials Group, Announces Plans for a Multi-center, Phase 2b Study to Evaluate MN-166 (ibudilast) in Chemotherapy-Induced Peripheral Neuropathy

LA JOLLA, Calif., Oct. 22, 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 it plans to initiate a multi-center, placebo-controlled, randomized Phase 2b trial to evaluate MN-166 (ibudilast) in chemotherapy-induced peripheral neuropathy (CIPN).
The clinical trial is a collaborative effort between MediciNova, the University of Sydney, and the Australasian Gastro-Intestinal Trials Group (AGITG). Dr. Janette Vardy, Professor of Cancer Medicine, University of Sydney in Australia, will be the lead principal investigator. The proposed clinical trial will evaluate MN-166 (ibudilast) as a potential treatment to reduce acute neurotoxicity severity and CIPN in patients with metastatic colorectal cancer. AGITG will provide funding for this study and MediciNova will provide study drug and regulatory support.Yuichi Iwaki, MD, PhD, President and Chief Executive Officer of MediciNova, Inc. commented, “We are excited to collaborate with Dr. Vardy on this grant-funded study to further explore the potential of MN-166 as a pharmacotherapy for CIPN. As we recently reported, our first clinical trial in CIPN showed that half of participants reported improved symptoms in the acute period and showed improved neurological parameters on clinical assessment with ibudilast treatment. There is a large unmet medical need for patients with this disorder.”Dr. Janette Vardy, the Principal Investigator for this study, commented, “The findings from our initial study were encouraging, and with the support of AGITG and MediciNova, we plan to explore further the potential clinical utility of ibudilast in a larger sample of patients who experience oxaliplatin-induced acute neurotoxicity and chronic CIPN.”About the Chemotherapy-induced Peripheral Neuropathy TrialThis study is a multi-center, randomized, double-blind, placebo-controlled Phase 2b trial to determine whether MN-166 (ibudilast) can decrease acute neurotoxicity symptoms and CIPN, and to determine whether ibudilast treatment results in fewer neurotoxicity-induced dose reductions in patients with metastatic colorectal cancer receiving oxaliplatin up to six months. We plan to enroll a total 100 patients in a 1:1 (ibudilast:placebo) ratio. Treatment (MN-166 (ibudilast) 60 mg/day or matching placebo) will commence two days prior to the first cycle of oxaliplatin chemotherapy and will continue for the duration of the oxaliplatin chemotherapy.About Chemotherapy-induced Peripheral NeuropathyPeripheral neuropathy is a set of symptoms caused by damage to the nerves that are outside of the brain and spinal cord. These distant nerves are called peripheral nerves. Some of the chemotherapy and other drugs used to treat cancer can damage peripheral nerves that carry sensations to the hands and feet. This damage results in chemotherapy-induced peripheral neuropathy (CIPN) and is a common side effect of cancer chemotherapy. Most commonly, people complain of “pins and needles” in their toes and fingers. CIPN may affect cancer outcomes due to reductions in chemotherapy dosing and/or premature treatment discontinuation and have a profound impact on quality of life and survivorship. According to a meta-analysis which included more than 4,000 patients, CIPN prevalence was 68% when measured in the first month after chemotherapy, 60% at 3 months, and 30% at 6 months or more (Seretny et al., 2014). Long-term neurotoxicity is an important issue for the growing number of cancer survivors, with the highest number of affected patients having been treated for breast and/or colon cancer.About MN-166 (ibudilast)
