STRENGTHEN YOUR HER2-TARGETED TREATMENT

PERJETA targets cells with too much HER2

In HER2+ cancer, the cancer cells have more HER2 receptors than normal cells. Targeted therapies like PERJETA and Herceptin^® (trastuzumab) are designed to fight these cancer cells by blocking the HER2 receptors. PERJETA and Herceptin work on different parts of the HER2 receptor, so they work together in combination with chemotherapy to build a stronger blockade. Because normal cells also have some HER2 receptors, targeted therapies may affect them.

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.

What are other possible serious side effects?

PERJETA should not be used in patients who are allergic to pertuzumab or to any of the ingredients in PERJETA

Infusion-related reactions: PERJETA is a medicine that is delivered into a vein through a needle. This process can cause reactions known as infusion-related reactions. The most common infusion-related reactions when receiving PERJETA, Herceptin, and docetaxel were feeling tired, abnormal or altered taste, allergic reactions, muscle pain, and vomiting. The most common infusion-related reactions when receiving PERJETA alone were fever, chills, feeling tired, headache, weakness, allergic reactions, and vomiting
