Indications

KANJINTI® is a prescription medicine used for the treatment of:

  • Adjuvant Breast Cancer

    • KANJINTI® is used for the treatment of early-stage breast cancer that is Human Epidermal growth factor Receptor 2-positive (HER2+) and that 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. 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.
    • KANJINTI® can be used in 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 trastuzumab.
  • Metastatic Breast Cancer

    • KANJINTI® has 2 approved uses in metastatic breast cancer:

      • KANJINTI® 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
      • KANJINTI® 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 trastuzumab.
  • Gastric Cancer

    • KANJINTI® 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 trastuzumab.

Important Safety Information

What are the possible Serious Side Effects with KANJINTI®?

KANJINTI® is not for everyone. Be sure to contact your doctor if you are experiencing any of the following potentially life threatening side effects:

HEART PROBLEMS

  • These include 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 a trastuzumab product, like KANJINTI®, 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 KANJINTI®.

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 KANJINTI®.

Tell your doctor if you:

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

    • KANJINTI® may result in the death of an unborn baby or birth defects.

    • Contraception should be used while receiving KANJINTI® and for seven months after your last dose of KANJINTI®.

    • Tell your doctor right away if you are exposed to KANJINTI® during pregnancy or within 7 months of becoming pregnant.

  • Have any signs of SEVERE LUNG PROBLEMS, including:
    • 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

  • 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 trastuzumab plus chemotherapy than in patients receiving chemotherapy alone.

    • Your doctor may test your blood and check for signs of low white blood cell counts.
