Anti-prolactin Receptor Antibody LFA102

**Semantic type:** Pharmacologic Substance

**Definition:** A neutralizing antibody against the prolactin receptor (PRLR) with potential antineoplastic activity. Upon administration, anti-prolactin receptor antibody LFA102 binds to PRLR and prevents the binding of the peptide hormone prolactin (PRL) to its receptor. This binding induces an antibody-dependent cellular cytotoxicity (ADCC) and may eventually prevent tumor cell proliferation in PRLR-positive cancer cells. PRLR/PRL signaling pathway is frequently overexpressed in breast and prostate cancer.
