Refanezumab Chemical Properties,Usage,Production
Uses
Refanezumab (GSK249320) is an IgG1-type humanized monoclonal antibody directed against myelin-associated glycoprotein (MAG). Refanezumab binds to MAG and blocks MAG-mediated inhibition of axonal regeneration. Refanezumab can cross the blood-brain barrier (BBB) in animal stroke models. Refanezumab has the potential for the enhancement of recovery of function poststroke[1][2].in vivo
Refanezumab (GSK249320; 10 mg/kg; IV; starting 24 hours post-stroke and continuing weekly for 6 more doses) shows larger increases in neuroscore and staircase test. Refanezumab by intravenous penetrates the lesion site and is associated with a small effect on functional outcomes when initiated 24 hours post-stroke[1].
| 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. |
