Indications

Adjuvant Breast Cancer

Herceptin^® (trastuzumab) is approved for the treatment of early-stage breast cancer that is Human Epidermal growth factor Receptor 2-positive (HER2+) and has spread into the lymph nodes, or is HER2-positive and has not spread into the lymph nodes. If it has not spread into the lymph nodes, the cancer needs to be estrogen receptor/progesterone receptor (ER/PR)-negative or have one high-risk feature.* Herceptin can be used in several different ways:

As part of a treatment course including the chemotherapy drugs doxorubicin, cyclophosphamide, and either paclitaxel or docetaxel. This treatment course is known as "AC→TH"
With the chemotherapy drugs docetaxel and carboplatin. This treatment course is known as "TCH"
Alone after treatment with multiple other therapies, including an anthracycline (doxorubicin) based therapy (a type of chemotherapy)

Patients are selected for therapy based on an FDA-approved test for Herceptin

*High risk is defined as ER/PR-positive with one of the following features: tumor size >2 cm, age <35 years, or tumor grade 2 or 3.

Metastatic Breast Cancer

Herceptin has 2 approved uses in metastatic breast cancer:

Herceptin in combination with the chemotherapy drug paclitaxel is approved for the first line treatment of Human Epidermal growth factor Receptor 2-positive (HER2+) metastatic breast cancer
Herceptin alone is approved for the treatment of HER2-positive breast cancer in patients who have received one or more chemotherapy courses for metastatic disease

Patients are selected for therapy based on an FDA-approved test for Herceptin

Gastric Cancer

Herceptin is approved, in combination with chemotherapy (cisplatin and either capecitabine or 5-fluorouracil), for the treatment of HER2-positive metastatic cancer of the stomach or gastroesophageal junction (where the esophagus meets the stomach) in patients who have not received prior treatment for their metastatic disease.

Patients are selected for therapy based on an FDA-approved test for Herceptin.

Possible Serious Side Effects With HERCEPTIN

Not all people have serious side effects, but side effects with HERCEPTIN^® (trastuzumab) therapy are common.

Although some people may have a life-threatening side effect, most do not.

Your doctor will stop treatment if any serious side effects occur.

HERCEPTIN is not for everyone. Be sure to contact your doctor if you are experiencing any of the following:

HEART PROBLEMS

These include heart problems—such as congestive heart failure or reduced heart function—with or without symptoms. The risk for and seriousness of these heart problems were highest in people who received both HERCEPTIN and a certain type of chemotherapy (anthracycline). In a study of adjuvant (early) breast cancer, one patient died of significantly weakened heart muscle. Your doctor will check for signs of heart problems before, during, and after treatment with HERCEPTIN.

INFUSION REACTIONS, including:

Fever and chills
Feeling sick to your stomach (nausea)
Throwing up (vomiting)
Pain (in some cases at tumor sites)
Headache
Dizziness
Shortness of breath

These signs usually happen within 24 hours after receiving HERCEPTIN.

Be sure to contact your doctor if you:

Are a woman who could become pregnant, or may be pregnant

HERCEPTIN may result in the death of an unborn baby or birth defects. Contraception should be used while receiving HERCEPTIN and for 7 months after your last dose of HERCEPTIN. If you are exposed to HERCEPTIN during pregnancy or within 7 months of becoming pregnant, you are encouraged to enroll in the MotHER Pregnancy Registry by contacting 1-800-690-6720 or visiting http://www.motherpregnancyregistry.com/ and report HERCEPTIN exposure to Genentech at 1-888-835-2555.

Severe shortness of breath
Fluid in or around the lungs
Weakening of the valve between the heart and the lungs
Not enough oxygen in the body
Swelling of the lungs
Scarring of the lungs

Your doctor may check for signs of severe lung problems when he or she examines you.

Have LOW WHITE BLOOD CELL COUNTS

Low white blood cell counts can be life threatening. Low white blood cell counts were seen more often in patients receiving HERCEPTIN plus chemotherapy than in patients receiving chemotherapy alone.

Your doctor may check for signs of low white blood cell counts when he or she examines you.

Side Effects Seen Most Often With HERCEPTIN

Some patients receiving HERCEPTIN for breast cancer had the following side effects:

Fever
Feeling sick to your stomach (nausea)

Please see additional select Important Safety Information throughout, and the accompanying full Prescribing Information, including Boxed WARNINGS.

Who is KADCYLA for?

KADCYLA is approved to treat HER2-positive breast cancer that has spread to other parts of the body (metastatic breast cancer) after prior treatment with trastuzumab (Herceptin^®) and a taxane. Prior treatment could have been for the initial treatment of breast cancer or for the treatment of cancer that had spread to other parts of the body.

What is the most important safety information I should know about KADCYLA?

KADCYLA is not the same medicine as trastuzumab (Herceptin).

Liver problems

KADCYLA may cause severe liver problems that can be life-threatening. Symptoms of liver problems may include vomiting, nausea, eating disorder (anorexia), yellowing of the skin (jaundice), stomach pain, dark urine, or itching

Heart problems

KADCYLA may cause heart problems, including those without symptoms (such as reduced heart function) and those with symptoms (such as congestive heart failure). Symptoms may include swelling of the ankles or legs, shortness of breath, cough, rapid weight gain of greater than 5 lb in less than 24 hours, dizziness or loss of consciousness, or irregular heartbeat

Pregnancy

Receiving KADCYLA during pregnancy can result in the death of an unborn baby and birth defects. Birth control should be used while you receive KADCYLA and for 7 months after your last dose of KADCYLA
If you are exposed to KADCYLA during pregnancy or become pregnant within 7 months of your last dose of KADCYLA, contact your healthcare provider right away; you are also encouraged to enroll in the MotHER Pregnancy Registry by calling 1-800-690-6720 or visiting http://www.motherpregnancyregistry.com/
You are also encouraged to report exposure to KADCYLA during pregnancy, or if you become pregnant within 7 months of your last dose to Genentech by calling 1-888-835-2555
If you are a mother who is breastfeeding, you should talk with your doctor about either stopping breastfeeding or stopping KADCYLA

Contact your doctor right away if you experience symptoms associated with these side effects.

What are the additional possible serious side effects of KADCYLA?

Not all people have serious side effects; however, side effects with KADCYLA treatment are common. It is important to know what side effects may happen and what symptoms you should watch for.

Lung problems

KADCYLA may cause lung problems, including inflammation of the lung tissue, which can be life-threatening. Signs of lung problems may include trouble breathing, cough, tiredness, and fluid in the lungs

Infusion-related reactions

Symptoms of an infusion-related reaction may include one or more of the following: the skin getting hot or red (flushing), chills, fever, trouble breathing, low blood pressure, wheezing, tightening of the muscles in the chest around the airways, or a fast heartbeat. Your doctor will monitor you for infusion-related reactions

Serious bleeding

KADCYLA can cause life-threatening bleeding. Taking KADCYLA with other medications used to thin your blood (antiplatelet) or prevent blood clots (anticoagulation) can increase your risk of bleeding. Your doctor should provide additional monitoring if you are taking one of these other drugs while on KADCYLA. Life-threatening bleeding may also happen with KADCYLA, even when blood thinners are not also being taken

Low platelet count

Low platelet count may happen during treatment with KADCYLA. Platelets help your blood to clot. Signs of low platelets may include easy bruising, bleeding, and prolonged bleeding from cuts. In mild cases there may not be any symptoms

Nerve damage

Symptoms may include numbness and tingling, burning or sharp pain, sensitivity to touch, lack of coordination, muscle weakness, or loss of muscle function

Skin reactions around the infusion site

KADCYLA may leak from the vein or needle and cause reactions such as redness, tenderness, skin irritation, or pain or swelling at the infusion site. If this happens, it is more likely to happen within 24 hours of the infusion

How will my doctor know if KADCYLA is right for me?

You must have a HER2 test to determine if your cancer is HER2-positive before taking KADCYLA, because benefit has been shown only in patients whose tumors are HER2-positive.

What are the most common side effects of KADCYLA?

The most common severe side effects of KADCYLA are:

Low platelet count
Liver problems
Low levels of red blood cells
Nerve problems
Low levels of potassium in the blood
Tiredness

The most common side effects seen in people taking KADCYLA were:

Tiredness
Nausea
Pain that affects the bones, muscles, ligaments, and tendons
Bleeding
Low platelet count
Headache
Liver problems
