Pharmacology
Humanized IgG1 kappa monoclonal antibody (anti-HER2) that inhibits proliferation of HER2-overexpressing tumor cells and mediates antibody-dependent cellular cytotoxicity (ADCC) preferentially on HER2-overexpressing cancer cells.
Palbociclib is an inhibitor of cyclin-dependent kinases (CDK) 4 and 6; it blocks progression of ER-positive breast cancer cells from G1 into S phase of the cell cycle, and in combination with antiestrogens decreases Rb protein phosphorylation, reduces E2F expression, and increases growth arrest.
