Refanezumab
Based on 1 Customer Validation
Refanezumab (GSK249320) is a brain-penetrant IgG1-type humanized monoclonal antibody directed against myelin-associated glycoprotein (MAG). Refanezumab binds to MAG and blocks MAG-mediated inhibition of axonal regeneration. Refanezumab has the potential for the enhancement of recovery of function poststroke.

-
Animal Model:Male Sprague Dawley rats (weight 361g)[1]
-
Dosage:10 mg/kg
-
Administration:IV; starting 24 hours post-stroke and continuing weekly for 6 more doses; starting seven days post-stroke and continuing weekly for 5 more doses
-
Result:Animals treated 24 hours post-stroke showed larger increases in neuroscore and staircase test as compared to controls, but animals treated 7 days post-stroke showed no significant behavioral benefit.
