WATCH VIDEO

Phesgo® (pertuzumab, trastuzumab, and hyaluronidase-zzxf) is a prescription medicine approved for use in combination with chemotherapy to treat certain kinds of early and metastatic HER2-positive breast cancer. It is designed to target HER2 receptors, disrupting cancer cell growth and interfering with HER2 signaling to help slow or stop tumor progression.
Phesgo is administered as an injection under the skin. The initial dose is a single 15 mL injection administered subcutaneously over approximately 8 minutes. This is followed by maintenance doses administered subcutaneously over approximately 5 minutes every 3 weeks. Your healthcare provider will determine the appropriate dosing schedule based on your specific medical condition and treatment progress.
Serious side effects of Phesgo include heart problems, death of an unborn baby, birth defects, and serious lung problems. Phesgo should not be used in patients who are allergic to Phesgo or to any of the ingredients in Phesgo. Other possible serious and sometimes fatal side effects include worsening of low white blood cell counts caused by chemotherapy and severe allergic reactions. The most common side effects of Phesgo when given with chemotherapy include hair loss, nausea, diarrhea, low levels of red and white blood cells, weakness or feeling tired, rash, and damage to the nerves.

Important Safety Information & Uses

Back to Top

[H2] What is PHESGO?
PHESGO is a prescription medicine approved for use in combination with chemotherapy for:
use prior to surgery (neoadjuvant treatment) in adults with HER2+, locally advanced, inflammatory, or early stage breast cancer (tumor is greater than 2 cm in diameter or node-positive). PHESGO should be used as part of a complete treatment regimen for early breast cancer.
use after surgery (adjuvant treatment) in adults with HER2+ early breast cancer that has a high likelihood of coming back.
PHESGO is also approved for use in combination with docetaxel in adults who have HER2+ 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.

[H3] What are the most serious side effects of PHESGO?

[IMG: Heart]

PHESGO may cause heart problems, including those without symptoms (such as reduced heart function) and those with symptoms (such as congestive heart failure).
The risk for and seriousness of these heart problems are highest in people who received both PHESGO and a certain type of chemotherapy (anthracycline)
Your doctor will check for signs of heart problems before, during, and after treatment with PHESGO. Based on test results, your doctor may hold or discontinue treatment with PHESGO
Contact a healthcare professional immediately for any of the following: new onset or worsening shortness of breath, cough, swelling of the ankles/legs, swelling of the face, palpitations, weight gain of more than 5 pounds in 24 hours, dizziness or loss of consciousness

[IMG: Pregnancy]

Receiving PHESGO during pregnancy can result in the death of an unborn baby and birth defects.
Birth control should be used while receiving PHESGO and for 7 months after your last dose of PHESGO. If you are a mother who is breastfeeding, you should talk with your doctor about either stopping breastfeeding or stopping PHESGO
If you think you may be pregnant, you should contact your healthcare provider immediately
If you are exposed to PHESGO during pregnancy, or become pregnant while receiving PHESGO or within 7 months following the last dose of PHESGO, you are encouraged to report PHESGO exposure to Genentech at 1-888-835-2555

[H1] WHAT IS PHESGO?

[H2] PHESGO combines IV PERJETA (pertuzumab)
and Herceptin (trastuzumab) into 1 injection

PERJETA and Herceptin are two HER2-targeted therapies. While they work together, each treatment is designed to block a different part of the HER2 receptor to stop cells from growing and dividing into new cancer cells. Normal cells also have HER2 receptors, so therapies like PERJETA with Herceptin, or PHESGO, may also affect them.

PHESGO is injected under the skin and works in the same way as IV PERJETA and Herceptin to treat HER2+ breast cancer. PHESGO also contains hyaluronidase, a protein that helps the body absorb the two medicines and allows them to be given as a single injection under the skin in just minutes.

[IMG: Pertuzumab and trastuzumab combined into a single injection]

[H2] PHESGO may help make treatment appointments go faster

PHESGO is a single ~5-minute injection given under the skin,* while PERJETA + Herceptin are given as an intravenous (IV) infusion that can take about 60-150 minutes.

[IMG: PERJETA + Herceptin are given over an approximate time span of 1 to 2.5 hours through an IV. PHESGO is given differently and in minutes.]

*The first dose is given in ~8 minutes. This does not account for observation time and other aspects of treatment. Actual clinic time may vary.

[IMG: Question mark]

[H5] Did you know?
In a clinical study, 85% of people preferred PHESGO over PERJETA + Herceptin and the most common reason was less time spent in the clinic.

NEXT: REAL STORIES

[H1] UNDERSTANDING HER2+ BREAST CANCER

HER2+ BREAST CANCER

EARLY VS METASTATIC BREAST CANCER

[H2] What is HER2-positive (HER2+) breast cancer?
All the cells in the body—healthy and cancerous—have HER2 receptors. But HER2+ breast cancer cells have too many HER2 receptors, which makes them grow and divide faster than other types of cells. This causes tumors to form.

[H3] NORMAL CELL

[IMG: A normal cell with label for the HER2 Receptor; shows a normal amount of HER2, which means cells grow and divide normally]

[H3] HER2+ CANCER CELL

[IMG: A HER2-positive cancer cell with label for the HER2 Receptor; shows too much HER2, which means cells grow and divide too quickly]

[H2] How does my doctor know that my breast cancer is HER2+?
Your doctor will know that your breast cancer is HER2+ by ordering a HER2 test. This test should be done before any breast cancer treatment is started. PHESGO has been shown to work only in people with HER2+ breast cancer.

[H2] What should I know about HER2+ breast cancer?
Not all HER2+ breast cancers are the same. Before recommending a treatment plan, your healthcare team will consider a few other factors about your specific cancer, as well as your medical history, condition, and personal preferences.

[H3] Here are some of the factors your healthcare team will look at:

[IMG: A woman with indicators pointing to lymph nodes around or near the collarbone, in the armpits, and near the breastbone]

[H5] Lymph node status
Your doctor will check to see if the cancer cells are in nearby glands called lymph nodes. If cancer cells are found in one or more lymph nodes, the cancer is called “node-positive” (node+).

[H5] Hormone receptor status
Two hormones naturally found in your body are estrogen and progesterone. These hormones attach to hormone receptors on cells.
Some cancer cells also have hormone receptors—they can have estrogen receptors, progesterone receptors, or both. This is called “hormone receptor-positive” breast cancer. Cancer cells that don’t have these receptors are called “hormone receptor-negative” breast cancer.

[H5] Tumor size and grade
The size of the tumor is how large it is at its widest point. The grade of the tumor is how different cancer cells look from healthy cells.

Grade 1
Cells grow slowly and look more like normal breast tissue.
Grade 2
Cells look somewhat different from healthy breast tissue and grow faster than in grade 1, but not as fast as in grade 3.
Grade 3
Cells look very different from normal tissue and will likely grow and spread quickly.

[H2] Early vs metastatic breast cancer
You might have been told you have early breast cancer or metastatic breast cancer. You may even have experience with both.
Early breast cancer means the cancer started in the breast and has not spread to other parts of the body. However, cancer cells may be found in nearby glands called lymph nodes.
Metastatic breast cancer means the cancer has spread to other parts of the body, such as the lungs, liver, or bones.
PHESGO can be used for both early and metastatic breast cancer, but each has a different plan.
