anti-CXCR4 monoclonal antibody PF-06747143
A humanized immunoglobulin (Ig) G1 monoclonal antibody (mAb) against C-X-C chemokine receptor type 4 (CXCR4), with potential antineoplastic activity. Upon administration, anti-CXCR4 mAb PF-06747143 binds to CXCR4, thereby preventing the binding of stromal cell-derived factor-1 (SDF-1 or CXCL12) to CXCR4 and inhibiting CXCR4 activation. This results in decreased proliferation and migration of CXCR4-expressing tumor cells. In addition, PF-06747143 promotes cell death through the induction of both complement-dependent cytotoxicity (CDC) and antibody-dependent cellular cytotoxicity (ADCC). CXCR4, a chemokine receptor belonging to the G protein-coupled receptor (GPCR) family, is upregulated in several tumor cell types and plays an important role in cancer cell proliferation, survival, and chemotaxis, and in tumor angiogenesis. Check for active clinical trials using this agent. (NCI Thesaurus)
