A Phase-2b, Double-Blind, Randomized Controlled Trial to Evaluate the Activity and Safety of Inebilizumab in Anti-Nmda Receptor Encephalitis and Assess Markers of Disease
University of Utah
Summary
Determine the difference in the modified Rankin score at 16 weeks in participants with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis treated with "first-line" immunomodulatory therapies provided as standard-of-care, and either inebilizumab (investigational agent) or placebo.
Description
N-methyl-D-aspartate receptor (NMDAR) encephalitis is one of the most common causes of autoimmune encephalitis, with prevalence exceeding herpes encephalitis in industrialized nations. Typically, the disease affects patients age 10-50 causing prominent psychiatric symptoms, altered consciousness, seizures, movement disorders and life-threatening dysautonomia. Intensive care, including cardiorespiratory support is required in 75% of cases. The diagnosis is confirmed by detection of IgG autoantibodies against central nervous system NMDAR in the cerebrospinal fluid. Despite the severity of the il…
