CervoMed Reports Significant Reduction in Neurodegeneration Biomarker from Phase 2b RewinD-LB Trial
CervoMed has shared new data from the Phase 2b RewinD-LB trial demonstrating neflamapimod treatment led to a significant reduction in the widely used neurodegeneration biomarker plasma GFAP and an increase in A42/40 ratio, an inverse marker of neuroinflammation and amyloidogenesis. In addition, neflamapimod treatment showed a trend towards reducing plasma neurofilament light chains levels. These data were presented on December 1, 2025, at the 18th Clinical Trials on Alzheimer's Disease, CTAD, Conference in San Diego, California. A second presentation will take place in an oral late-breaking session at the conference on December 4th, 2025, in which Dr. John-Paul Taylor, MBBS, MRCPsych, PhD, Professor of Translational Dementia Research at Newcastle University, will provide the clinical outcome results from RewinD-LB.
