About
KEYTRUDA

KEYTRUDA is not chemotherapy or radiation therapy—it is an immunotherapy.

Ask your oncologist about KEYTRUDA

If you have a type of triple-negative breast cancer, an oncologist can help you learn more about your diagnosis and what a treatment plan with KEYTRUDA may look like.

Here are some questions that may be helpful during your next appointment:
  • What type of TNBC do I have?
  • What is the difference between high-risk early-stage and advanced TNBC?
  • Is KEYTRUDA an option for me?
  • What would a treatment plan with KEYTRUDA look like?
  • How soon should I start treatment?
  • What are the potential risks and benefits of KEYTRUDA?

How is TNBC treated with KEYTRUDA?

KEYTRUDA is an immunotherapy that works with your immune system to help treat certain cancers.

If you have early-stage breast cancer and are at high risk of your cancer returning, KEYTRUDA may be used with chemotherapy before surgery, then alone after surgery.

KEYTRUDA may be included as part of your first treatment for a certain type of advanced TNBC. KEYTRUDA and chemotherapy may help treat certain patients with advanced TNBC in 2 different ways.

Have you or someone you care about been diagnosed recently with high-risk early-stage TNBC?

FDA-Approved Indications

KEYTRUDA is a prescription medicine used to treat a kind of cancer called triple-negative breast cancer (TNBC).

  • KEYTRUDA may be used with chemotherapy medicines as treatment before surgery and then continued alone after surgery when you have early-stage breast cancer, and are at high risk of your breast cancer coming back.
  • KEYTRUDA may be used with chemotherapy medicines when your breast cancer has returned and cannot be removed by surgery or has spread, and tests positive for “PD-L1.”

PD-L1 = programmed death ligand 1.

Important Safety Information

KEYTRUDA is a medicine that may treat certain cancers by working with your immune system. KEYTRUDA can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. You can have more than one of these problems at the same time. These problems may happen any time during treatment or even after your treatment has ended.

Call or see your health care provider right away if you develop any signs or symptoms of the following problems or if they get worse. These are not all of the signs and symptoms of immune system problems that can happen with KEYTRUDA:

Lung problems: cough, shortness of breath, or chest pain.

Intestinal problems: diarrhea (loose stools) or more frequent bowel movements than usual; stools that are black, tarry, sticky, or have blood or mucus; or severe stomach-area (abdomen) pain or tenderness.

Liver problems: yellowing of your skin or the whites of your eyes; severe nausea or vomiting; pain on the right side of your stomach area (abdomen); dark urine (tea colored); or bleeding or bruising more easily than normal.

Hormone gland problems: headaches that will not go away or unusual headaches; eye sensitivity to light; eye problems; rapid heartbeat; increased sweating; extreme tiredness; weight gain or weight loss; feeling more hungry or thirsty than usual; urinating more often than usual; hair loss; feeling cold; constipation; your voice gets deeper; dizziness or fainting; changes in mood or behavior, such as decreased sex drive, irritability, or forgetfulness.

Kidney problems: decrease in the amount of your urine; blood in your urine; swelling of your ankles; loss of appetite.

Skin problems: rash; itching; skin blistering or peeling; painful sores or ulcers in your mouth or in your nose, throat, or genital area; fever or flu-like symptoms; swollen lymph nodes.

Complications, including graft-versus-host disease (GVHD), in people who have received a bone marrow (stem cell) transplant that uses donor stem cells (allogeneic). These complications can be serious and can lead to death. These complications may happen if you underwent transplantation either before or after being treated with KEYTRUDA. Your health care provider will monitor you for these complications.

Getting medical treatment right away may help keep these problems from becoming more serious. Your health care provider will check you for these problems during treatment with KEYTRUDA. They may treat you with corticosteroid or hormone replacement medicines. They may also need to delay or completely stop treatment with KEYTRUDA if you have severe side effects.

Before you receive KEYTRUDA, tell your health care provider if you have immune system problems such as Crohn’s disease, ulcerative colitis, or lupus; have had an organ or tissue transplant, including corneal transplant, or have had or plan to have a bone marrow (stem cell) transplant that uses donor stem cells (allogeneic); have had radiation treatment in your chest area; have a condition that affects your nervous system, such as myasthenia gravis or Guillain-Barré syndrome.

If you are pregnant or plan to become pregnant, tell your health care provider. KEYTRUDA can harm your unborn baby. If you are able to become pregnant, you will be given a pregnancy test before you start treatment. Use effective birth control during treatment with KEYTRUDA and for 4 months after your last dose of KEYTRUDA. Tell them right away if you think you may be pregnant or you become pregnant during treatment with KEYTRUDA.

Tell your health care provider if you are breastfeeding or plan to breastfeed. It is not known if KEYTRUDA passes into your breast milk. Do not breastfeed during treatment with KEYTRUDA and for 4 months after your last dose of KEYTRUDA.
