MediciNova Announces Completion of Enrollment in the Phase 2 Clinical Trial of MN-166 (ibudilast) in Hospitalized COVID-19 Patients at Risk for Acute Respiratory Distress Syndrome
About the Clinical Trial
This study was a multi-center, randomized (1:1), double-blind, placebo-controlled, parallel-group study of MN-166 (ibudilast) in hospitalized patients with COVID-19 at risk for developing ARDS and receiving standard of care, including anticoagulation therapy. Major inclusion criteria for trial eligibility included confirmed SARS-CoV-2 infection, oxygen saturation (SpO2) ≤92% on room air, chest imaging with abnormalities consistent with COVID-19 pneumonia, and had at least one risk factor that posed a higher risk for more severe illness from COVID-19. Eligible participants were randomly assigned to MN-166 (ibudilast) 100 mg/day or matching placebo treatment for 7 days. The co-primary objectives include the proportion of subjects free from respiratory failure and subjects’ change in clinical status measured by the NIAID scale at Day 7. Assessments performed include clinical status, oxygen therapy use status, adverse events, and survival status.
About Acute Respiratory Distress Syndrome
Acute respiratory distress syndrome (ARDS) is a frequently lethal lung condition caused by excessive inflammation for which there are no effective therapies beyond supportive care. Normally, the lung exchanges oxygen for carbon dioxide in small airway sacs called alveoli. In ARDS, there is extensive inflammation and tissue injury in the alveoli, and loss of the surfactant, a substance necessary for keeping the alveoli open. These changes prevent the lungs from filling properly with air and providing the body with enough oxygen, causing life-threatening difficulty breathing. ARDS may develop over a few days, or it can get worse very quickly. The first symptom of ARDS is usually shortness of breath. Other signs and symptoms of ARDS are low blood oxygen, and shallow and/or rapid breathing. Infections, including the flu, coronavirus, other viruses, are the most common cause of ARDS. The rate of death in the hospital is approximately 40% for ARDS patients.
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 for glioblastoma, CIPN (chemotherapy-induced peripheral neuropathy), and substance use disorder. In addition, MN-166 (ibudilast) is being evaluated in patients that are at risk for developing acute respiratory distress syndrome (ARDS).
