Bruce Cree, MD, PhD, MAS: Inebilizumab in Neuromyelitis Optica Spectrum Disorder


The clinical research director of the University of California, San Fransciso’s Multiple Sclerosis Center discussed the findings of a 230-patient study of inebilizumab versus placebo in NMOSD.

“This was a large undertaking. It involved 99 centers in 24 countries, and the goal of the study was to determine whether this monoclonal antibody that depletes B cells was clinically effective at preventing relapses in neuromyelitis optica spectrum disorder…these results were very positive.”

At the 2019 American Academy of Neurology (AAN) Annual Meeting, May 4-10, in Philadelphia, 3 separate presentations focused on the positive results of an investigational therapy for a condition lacking even a single medicine: neuromyelitis optica spectrum disorder (NMOSD). Additionally, all 3 therapies being tested operate through a different mechanism of action, offering a drastic level of hope for the clinicians treating NMO.

One of those studies, N-MOmentum, was led by Bruce Cree, MD, PhD, MAS, clinical research director, UCSF Multiple Sclerosis Center, and explored the effects of inebilizumab in a 3:1 randomization compared with placebo for 6.5 months.

The humanized monoclonal antibody binds to and depletes CD19+ B cells, and in this phase 3 study of 230 patients with NMOSD, a number of significant decreases in key end points were reported due to treatment. In a conversation with NeurologyLive, Cree shared insight from the findings, including that inebilizumab reduced the incidence of disease relapse by 78%.
