CLINICAL TRIAL SERVICES
The Buffalo Neuroimaging Analysis Center (BNAC) is a dedicated research center that has expertise in clinical trials using preclinical chronic progressive models of multiple sclerosis (MS).
In contrast to experimental autoimmune encephalomyelitis (EAE), the Theiler Murine Encephalomyelitis Virus (TMEV) model is an axonal viral infection-mediated demyelinating disease represented by biphasic relapsing and progressive disease course, like MS. TMEV is characterized by an initial acute demyelination that is followed by prolonged inflammation of the axons resulting in progressively adverse demyelination and axonal loss. TMEV-infected animals exhibit progressive motor deterioration which is associated with a development of the brain and spinal cord atrophy.
MS therapies use small molecules designed to target CNS infiltratory inflammatory cells with higher metabolic rate, aim to restrict such sporadic immune activity during MS relapses. TMEV is a demyelinating disease model in which direct immunization is not the primary driver. TMEV is a protracted viral axonal infection mediated demyelinating disease in mice for modeling MS. In its biphasic disease timeline, the inability of the SJL mice to completely eliminate inflammation within the axons leads to the initial acute demyelination and is followed by prolonged inflammation of the axons resulting in progressively adverse demyelination.
Because of striking similarities with progressive MS disease course and its pathology, the TMEV has been increasingly used to test efficacy of DMTs. BNAC has recently conducted several preclinical trials with currently FDA approved DMTs, as well as those in various stages of preclinical and clinical development, using the TMEV model of MS.
