Overview

Zanidatamab + vinorelbine is a combination drug regimen under investigation primarily for the treatment of **HER2-positive breast cancer**. **Zanidatamab** is a bispecific monoclonal antibody that targets two distinct epitopes on the HER2 receptor, enhancing HER2 blockade and mediating immune effector functions via antibody-dependent cellular cytotoxicity and other mechanisms. **Vinorelbine** is a vinca alkaloid chemotherapeutic agent that inhibits microtubule assembly, leading to cell cycle arrest and apoptosis. This combination aims to leverage targeted HER2 inhibition and cytotoxic chemotherapy for synergistic antitumor effects, especially in patients with metastatic or previously treated HER2-positive breast cancer. Zanidatamab is developed by Jazz Pharmaceuticals and was investigated in combination with vinorelbine within phase 1 and phase 3 clinical settings[1][3][4].
