MediciNova Announces Positive Clinical Results Regarding MN-166 (ibudilast) for Prevention of Chemotherapy-induced Peripheral Neuropathy Published in Cancer Chemotherapy and Pharmacology
MediciNova, Inc. reported positive clinical findings for MN-166 (ibudilast) in preventing chemotherapy-induced peripheral neuropathy (CIPN), as detailed in Cancer Chemotherapy and Pharmacology. A pilot study involving 14 patients revealed that co-treatment with MN-166 improved or stabilized neurotoxic symptoms caused by oxaliplatin. Notably, 10 out of 12 participants showed no worsening of symptoms. Pharmacokinetic analysis indicated MN-166 did not affect oxaliplatin exposure. The results suggest MN-166 may play a significant role in enhancing the quality of life for cancer patients undergoing chemotherapy.
- Majority of participants experienced improved or stabilized neurotoxicity symptoms with MN-166 treatment.
- Pharmacokinetic analysis showed no adverse effect on oxaliplatin exposure.
- Positive implication for enhancing quality of life in cancer patients undergoing chemotherapy.
- None.
LA JOLLA, Calif., Sept. 24, 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 positive clinical findings published in Cancer Chemotherapy and Pharmacology regarding MN-166 (ibudilast) as a treatment for prevention of chemotherapy-induced peripheral neuropathy (CIPN).
The publication, entitled “Ibudilast for prevention of oxaliplatin-induced acute neurotoxicity: a pilot study assessing preliminary efficacy, tolerability, and pharmacokinetic interactions in patients with metastatic gastrointestinal cancer”, is the result of a collaborative effort between MediciNova and Dr. Janette Vardy, Professor of Cancer Medicine, University of Sydney Concord Cancer Centre in Australia. The authors report that co-administration of MN-166 (ibudilast) with oxaliplatin resulted in improvement or stabilization of oxaliplatin-induced neurotoxicity in the majority of participants treated with oxaliplatin.
This prospective, open-label, sequential crossover study was conducted to assess whether MN-166 (ibudilast) can reduce acute peripheral neuropathy symptoms in patients with metastatic upper gastrointestinal or colorectal cancer. A total 16 patients consented, and 14 patients completed two cycles of oxaliplatin-containing chemotherapy, one cycle with conventional chemotherapy (Cycle A) and one cycle of chemotherapy with concurrent MN-166 treatment (Cycle B). As a cross-over design, each participant acted as their own control. Participants underwent a number of assessments for neurotoxicity on Day 3 of each cycle, and at the completion of each cycle, including the Oxaliplatin-Specific Neurotoxicity Scale (OSNS), the Total Neuropathy Score Clinical (TNSc), the Functional Assessment of Cancer Therapy/Gynaecologic Oncology Group—Neurotoxicity (FACT/GOG-Ntx13), and the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) neuropathy subscale.
Major findings from the publication are as follows:
- Across all neurotoxicity measures, a majority of participants experienced either an improvement or no worsening of neurotoxicity with MN-166 (ibudilast) treatment
- According to OSNS assessments, 12 out of 14 participants reported acute neurotoxicity (Grade 1 or 2) in both cycles. Of those, 10 out of 12 participants were unchanged and 2 participants had improved symptoms from Grade 2 to Grade 1 with MN-166 (ibudilast) co-treatment.
- According to score changes with FACT/GOG-Ntx13, TNSc and NCI-CTCAE, a majority of participants had no worsening of scores at the Day 3 and end of cycle time-points for Cycle B compared to Cycle A.
- Pharmacokinetic analysis indicated no effect of MN-166 (ibudilast) on systemic exposure of oxaliplatin.
Yuichi Iwaki, M.D., Ph.D., President and Chief Executive Officer of MediciNova, Inc., commented, “We are very pleased to report positive results from this study. Acute neurotoxicity, which predicts chronic CIPN, usually recurs with oxaliplatin chemotherapy and in most cases, patients experience worsening of neurotoxicity symptoms with continued chemotherapy. What makes this remarkable is that half of participants reported improved symptoms in the acute period and showed improved neurological parameters on clinical assessment with ibudilast treatment.”
About Chemotherapy-induced Peripheral Neuropathy
Peripheral 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
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.
