Balixafortide (Polyphor) is a synthetic cyclopeptide derived from polyphemusin that inhibits C-X-C motif chemokine receptor 4 (CXCR4), a G-protein coupled receptor that exclusively binds to its ligand, stromal cell-derived factor-1 (SDF-1). The CXCR4/SDF-1 axis stimulates cell migration, induces cell proliferation and angiogenesis, and promotes invasion in both cancer cells and cells of the immune system. CXCR4 antagonists block the interaction of CXCR4 and SDF-1, inhibiting cancer metastasis by limiting the migratory and invasive potential of the cancer cells.
Although normal breast cells do not express CXCR4, approximately 75% of triple-negative breast cancer patients have high levels of CXCR4 expression. Additionally, SDF-1 is selectively expressed in the lymph nodes, lungs, liver, and bone marrow, which are the most common sites of breast cancer metastasis.
