See how your treatment experience may evolve after neoadjuvant treatment

Following a diagnosis of HER2-positive early breast cancer (HER2+ eBC), a doctor will recommend a treatment plan based on factors such as HER2 status, nodal status, hormone receptor status, the size of the tumor, your medical history, and personal preferences. It’s important to understand the different approaches to treatment so that you can discuss them with your doctor.

See below to better understand how the treatment decisions made after a diagnosis may change the targeted treatment options available later in your eBC experience.

Your treatment experience for HER2+ eBC began with diagnosis


Your doctor may recommend starting HER2-targeted treatment before surgery

*You will also be given chemotherapy, but the dosing schedule and number of cycles will depend on which type of chemotherapy you receive.

Who is KADCYLA for?

Early Breast Cancer

KADCYLA is a prescription medicine used as an adjuvant (after surgery) treatment for HER2-positive early breast cancer when the patient has taken neoadjuvant (before surgery) treatment including a taxane and trastuzumab (Herceptin®) and there is cancer remaining in the tissue removed during surgery.

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

What is the most Important Safety Information I should know about KADCYLA?

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 more than 5 pounds in 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 think you may be pregnant, you should contact your healthcare provider immediately
  • If you are exposed to KADCYLA during pregnancy or if you become pregnant within 7 months following your last dose of KADCYLA, you are encouraged to report KADCYLA exposure to Genentech by calling 1-888-835-2555
  • If you are a male patient with a female partner that could become pregnant, birth control should be used during treatment and for 4 months following your last dose of KADCYLA
  • You should not breastfeed during treatment and for 7 months after the last dose of 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?

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. Even when blood thinners are not also being taken, life-threatening bleeding may occur with KADCYLA

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. Your doctor will monitor you for symptoms of nerve damage

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

What are the most common side effects of KADCYLA?

The most common side effects in people taking KADCYLA for early breast cancer are:

  • Tiredness
  • Nausea
  • Liver problems
  • Pain that affects the bones, muscles, ligaments, and tendons
  • Bleeding
  • Low platelet count
  • Headache
  • Weakness, numbness, and pain in the hands and feet
  • Joint pain

You are encouraged to report side effects to Genentech and the FDA. You may contact Genentech by calling 1-888-835-2555. You may contact the FDA by visiting www.fda.gov/medwatch or calling 1-800-FDA-1088.

Talk to a healthcare professional for more information about the benefits and risks of KADCYLA.

  • Adjuvant treatment

    The treatment that is given after surgery to kill any remaining cancer cells and lower your risk of the cancer returning. The goal of adjuvant treatment is to keep you cancer-free for as long as possible.

  • Chemotherapy

    A type of medication that kills cells that grow and divide rapidly, including cancer cells and normal cells.

  • Cycle

    A cycle is a course of treatment that is repeated on a regular schedule with periods of rest in between.

  • HER2 status

    HER2 stands for human epidermal growth factor receptor 2. HER2 is a type of protein found on the surface of cells in everyone that tells the cells to grow and divide. When breast cancer cells have too many HER2 receptors, they are called HER2-positive (HER2+).

  • Inflammatory

    When the breast is swollen, red, or inflamed as a result of the cancer cells blocking lymph vessels.

  • Infusion

    A method of putting fluids, including drugs, into the bloodstream. Also called intravenous infusion.

  • Lymph nodes

    Small, bean-shaped organs found throughout the body that store white blood cells and help remove cell waste, germs, and other harmful substances from the body.

  • Node positive

    This means your doctor has detected cancer cells in one or more of your lymph nodes.

  • Nodal status

    Cancer cells can sometimes appear in nearby structures known as "lymph nodes." When cancer cells appear in one or more lymph nodes, the cancer is said to be "node-positive" (node+).

  • Neoadjuvant treatment

    Treatment given before surgery to help reduce or get rid of cancer cells before surgery.

  • Pathologic complete response (pCR)

    A pCR means that no cancer cells were found in the tissue removed during surgery. A pCR is not the same as a cure.

  • Port

    A surgically implanted disc through which blood can be taken and medication can be given without repeated needle sticks

  • Residual disease

    If cancer cells are found in the tissue removed during surgery, it is known as residual disease.

  • Targeted therapies

    Designed to target specific characteristics of cancer cells. Targeted treatments may also affect normal cells

  • Tumor size

    The size of the tumor is how large it is at its widest point.

  • Hormone receptor status

    Two hormones naturally made by the body are called estrogen and progesterone. These hormones attach to hormone receptors on cells. Some tumors have hormone receptors—they can have estrogen receptors, progesterone receptors, or both. This is called “hormone receptor-positive” breast cancer. “Hormone receptor-negative” breast cancer is when the cancer cells do not have hormone receptors.

  • Hyaluronidase

    Hyaluronidase is a protein naturally found in most tissues of the body and helps enhance the way the body absorbs medicines injected under the skin. When PHESGO is injected, the hyaluronidase makes the tissue under the skin more absorbent temporarily so that it’s able to receive the medication.

  • Locally advanced

    Cancer that has spread from where it started to nearby tissue or lymph nodes.

  • Early-stage breast cancer

    Breast cancer that has not spread beyond the breast or the axillary lymph nodes.

  • HER2-targeted therapies

    A type of targeted cancer treatment that binds to HER2 receptors to fight cancer cells that have too many HER2 receptors.

  • Surgery

    The medical practice of treating injuries or disease by cutting into the body to physically remove tissue.
