Pertuzumab

Introduction

Pertuzumab is a targeted cancer therapy primarily used in the treatment of HER2-positive breast cancer. It is a monoclonal antibody that works by interfering with the HER2 receptor, slowing or stopping the growth of cancer cells. Pertuzumab is often used in combination with other cancer medications like trastuzumab and chemotherapy to enhance its effectiveness. This composition is administered under the supervision of a healthcare provider and is usually given as an intravenous infusion.

Uses of Pertuzumab

• Treatment of HER2-positive metastatic breast cancer
• Used in combination therapy for early-stage breast cancer
• Helps in reducing the risk of cancer progression and recurrence

How Pertuzumab Works

Pertuzumab works by binding to the HER2 receptor on cancer cells, blocking its interaction with other HER family receptors. This inhibits cell signaling that promotes tumor growth and survival. When used with trastuzumab and chemotherapy, it provides a more comprehensive blockade of the HER2 pathway, resulting in improved treatment outcomes.

Benefits of Pertuzumab

• Effective in treating HER2-positive breast cancer
• Improves survival rates when combined with other therapies
• Reduces the risk of cancer returning
• Targeted therapy with fewer effects on healthy cells
