HIDE SMILES / InChI
VX-745 (Neflamapimod) is a brain-penetrant highly selective, orally bioavailable drug that inhibits the intracellular enzyme p38 mitogen-activated protein kinase alpha (MAPKa). It is currently in phase 2 clinical studies in patients with early Alzheimer's disease. The targeting of p38 MAPK by VX-745 was associated with the suppression of the release of inflammatory mediators, including interleukin (IL)-1β and tumor necrosis factor (TNF)α, known to be implicated in exacerbating the pathophysiology of rheumatoid arthritis (RA). The drug was in phase II of the clinical trial for RA, but that studies were discontinued.

Sample Use Guides

VX-745 dose level 1 twice daily
Route of Administration: Oral
Cell data for VX-745 in a human peripheral blood mononuclear cell (PBMC) assay provided IC50 values of 56 and 52 nM for IL-1β and TNFα, respectively, and VX-745 blocked IL-6 and IL-8 production induced by IL-1 and TNFα, and cyclooxygenase (COX)-2 synthesis mediated by LPS and IL-1β. In a human whole blood assay, IC50 values were 152 and 177 nM for IL-1β and TNFα inhibition, respectively.
