Perjeta (Pertuzumab) in the USA: Cost, Uses & Access Guide

What is Perjeta (Pertuzumab)?

Perjeta (Pertuzumab) is a targeted cancer therapy used in combination with other treatments for HER2-positive breast cancer. It is a monoclonal antibody designed to block HER2 receptors, helping slow or stop the growth of cancer cells.

Developed by Genentech, Perjeta is widely used in the United States as part of advanced breast cancer treatment protocols.

It is commonly used in combination with:

  • Trastuzumab (Herceptin)

This combination significantly improves treatment outcomes for eligible patients.


How Perjeta Works

Perjeta targets the HER2 receptor, which promotes cancer cell growth in certain breast cancers.
