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.

Metastatic Breast Cancer

KADCYLA is a prescription medicine used 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.

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

Important Safety Information

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

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
