PERJETA FOR HER2+ EARLY BREAST CANCER

Learn about PERJETA-based treatment before surgery

Treatment before breast cancer surgery (also known as neoadjuvant treatment) may be an option for HER2-positive (HER2+) early breast cancer. Doctors may choose neoadjuvant treatment for early breast cancer to shrink a tumor.

PERJETA is part of an FDA-approved neoadjuvant treatment regimen for HER2+ early breast cancer, along with Herceptin^® (trastuzumab) and chemotherapy. Talk to your doctor to determine if treatment before breast cancer surgery may be right for you.

Talking with your doctor

Some tips on how to get the most out of your doctor’s appointments.

What does PERJETA treat?

PERJETA^® (pertuzumab) is approved for use in combination with Herceptin^® (trastuzumab) and docetaxel in people who have HER2-positive breast cancer that has spread to different parts of the body (metastatic) and who have not received anti-HER2 therapy or chemotherapy for metastatic breast cancer.

PERJETA is approved for use in combination with Herceptin and chemotherapy for:

use prior to surgery (neoadjuvant treatment) in people with HER2-positive, locally advanced, inflammatory, or early stage breast cancer (tumor is greater than 2 cm in diameter or node-positive). PERJETA should be used as part of a complete treatment regimen for early breast cancer.
use after surgery (adjuvant treatment) in people with HER2-positive early breast cancer that has a high likelihood of coming back.
