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.

Ribociclib is a CDK4/6 inhibitor that blocks cyclin D-CDK4/6-mediated phosphorylation of the retinoblastoma protein (pRb), arresting the cell cycle in the G1 phase and reducing proliferation in breast cancer models; in combination with antiestrogen therapy (letrozole or fulvestrant), it produces greater tumor growth inhibition than either agent alone.
