About the Trial

The study is a randomized, placebo-controlled, double-blind, inpatient Phase 2a study of MN-166 (ibudilast) in opioid-dependent abusers of prescription opioids and/or heroin. The study duration is approximately 6 weeks per subject. The crossover study design includes initial detoxification followed by randomization to ibudilast 50 mg BID or placebo. Subjects are maintained on each dose for at least two to three consecutive weeks (one week stabilization + one and a half weeks testing). During test weeks, participants receive oxycodone (0, 15, or 30 mg PO) in random order on separate days. For each dose, a sample followed by a choice session is completed. During the choice session, a "drug versus money" self-administration paradigm is employed. The primary aim of the study is to investigate the ability of MN-166 to alter the reinforcing, analgesic, subjective, performance, and physiological effects of oxycodone, a commonly abused prescription opioid.

About MN-166 (ibudilast)

MN-166 (ibudilast) has been marketed in Japan and Korea since 1989 to treat post-stroke complications and bronchial asthma. MediciNova licensed MN-166 (ibudilast) from Kyorin Pharmaceutical for potential utility in relapse-remitting multiple sclerosis (RRMS). Intellectual property was additionally established or obtained by MediciNova in progressive MS and other neurological conditions. MN-166 (ibudilast) is a first-in-class, orally bioavailable, small molecule phosphodiesterase (PDE) 4 and 10 inhibitor and a macrophage migration inhibitory factor (MIF) inhibitor that suppresses pro-inflammatory cytokines and promotes neurotrophic factors. It attenuates the activated glia cells, which play a major role in certain neurological conditions. Ibudilast's anti-neuroinflammatory and neuroprotective actions have been demonstrated in preclinical and clinical study results and provide the rationale for its therapeutic utility in neurodegenerative diseases (e.g., progressive MS and Amyotrophic Lateral Sclerosis [ALS]), substance abuse/addiction and chronic neuropathic pain.
