STRENGTHEN YOUR HER2-TARGETED TREATMENT

PERJETA targets breast cancer cells with too much HER2

In HER2+ cancer, the cancer cells have more HER2 receptors than normal cells. Targeted therapies like PERJETA and Herceptin 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 docetaxel 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^® (pertuzumab) is approved for use prior to surgery in combination with Herceptin^® (trastuzumab) and docetaxel in people with HER2-positive, locally advanced, inflammatory, or early stage (tumor is greater than 2 cm in diameter or node positive) breast cancer. PERJETA should be used as part of a complete treatment regimen for early stage breast cancer. This use of PERJETA is based on an improvement in the percentage of patients whose cancer shrinks or disappears after treatment. Currently, no data have shown whether or not treatment with PERJETA prior to surgery improves survival.

The safety of PERJETA in combination with doxorubicin-containing regimens has not been established
The safety of PERJETA administered for greater than 6 cycles for early-stage breast cancer has not been established.

Important Safety Information

What should I know about side effects with PERJETA?

Not all people have serious side effects; however, side effects with PERJETA therapy are common. It is important to know what side effects may happen and what symptoms you should watch for
Your doctor may stop treatment if serious side effects happen. Be sure to contact your healthcare team right away if you have questions or are worried about any side effects

What are the most serious side effects?

PERJETA may cause heart problems, including those without symptoms (such as reduced heart function) and those with symptoms (such as congestive heart failure).

Your doctor may run tests to monitor your heart function before and during treatment with PERJETA
Based on test results your doctor may hold or discontinue treatment with PERJETA

Receiving PERJETA during pregnancy can result in the death of an unborn baby and birth defects.

Birth control should be used while receiving PERJETA and for 7 months after your last dose of PERJETA. If you are a mother who is breastfeeding, you should talk with your doctor about either stopping breastfeeding or stopping PERJETA
If you think you may be pregnant, you should contact your healthcare provider immediately
If you are exposed to PERJETA during pregnancy, or become pregnant while receiving PERJETA or within 7 months following the last dose of PERJETA in combination with Herceptin, you are encouraged to enroll in the MotHER Pregnancy Registry by contacting 1-800-690-6720 or visiting http://www.motherpregnancyregistry.com/ and report PERJETA exposure to Genentech at 1-888-835-2555

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

Severe allergic reactions: Some people receiving PERJETA may have severe allergic reactions, called hypersensitivity reactions or anaphylaxis. This reaction may be severe, may happen quickly, and may affect many areas of the body

How will my doctor and I know if PERJETA is right for me?

PERJETA has only been shown to work in people with HER2-positive breast cancer. You must have a HER2 test to know if your breast cancer is HER2-positive before receiving an anti-HER2 treatment, such as PERJETA.

What are the most common side effects?

The most common side effects of PERJETA when given with Herceptin and docetaxel for treatment of breast cancer that has spread to other parts of the body (metastatic) are:
