Advanced gastric cancer

IS KEYTRUDA RIGHT FOR YOU?

Immunotherapy may be right for you.
It’s TRU. KEYTRUDA.

Understanding advanced gastric cancer

Gastric cancer, also known as stomach cancer, begins when cells in the stomach start to grow out of control. Cancer can also develop in the gastroesophageal junction (GEJ), which is where the esophagus joins the stomach. When the cancer has returned or spread it is known as advanced gastric or GEJ cancer.

There are several options to treat advanced gastric or GEJ cancer, including KEYTRUDA, an immunotherapy that is FDA-approved for certain patients with previously treated advanced gastric cancer that tests positive for PD-L1.

Talk to your doctor about PD-L1 biomarker testing and KEYTRUDA

Everyone’s advanced gastric cancer is different. To help develop a treatment plan that’s right for you, your doctor may order biomarker tests. These tests can measure your tumor for different biomarkers, including a biomarker called PD-L1. Biomarker tests help predict your response to certain treatments, such as KEYTRUDA. Talk to your doctor to see if a PD-L1 biomarker test is right for you.

How a PD-L1 Biomarker Test Works

How a PD-L1 biomarker test works:

  1. A tissue sample (biopsy) of your tumor is taken, and your doctor orders the test for PD-L1. If you've already had a biopsy, you may not have to get another one. Your doctor may be able to test your previous sample.
  2. Your doctor typically gets the results in about 7 to 10 days.
  3. You talk with your doctor to discuss treatment options based on your results.
  4. You may begin treatment with KEYTRUDA if you and your doctor have decided it’s right for you.
Questions You May Want to Ask Your Doctor About PD-L1 Biomarker Testing

Questions you may want to ask your doctor about PD-L1 biomarker testing:

  • Will you be testing my tumor for biomarkers for advanced gastric cancer, including PD-L1?
  • How would this test be helpful in determining my treatment plan?
  • Is KEYTRUDA right for me?

FDA-Approved Indications

KEYTRUDA is a prescription medicine used to treat a kind of stomach cancer called gastric or gastroesophageal junction (GEJ) adenocarcinoma that tests positive for “PD-L1.” KEYTRUDA may be used when your stomach cancer:

  • has returned or spread (advanced gastric cancer), and
  • you have received 2 or more types of chemotherapy including fluoropyrimidine and chemotherapy that contains platinum, and it did not work or is no longer working, and
  • if your tumor has an abnormal “HER2/neu” gene, you also received a HER2/neu‑targeted medicine and it did not work or is no longer working.

PD-L1 = programmed death ligand 1; HER2/neu = human epidermal growth factor receptor 2.

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. These problems may happen any time during treatment or even after your treatment has ended.

Call or see your doctor right away if you develop any symptoms of the following problems or these symptoms get worse:

Lung problems (pneumonitis). Symptoms of pneumonitis may include shortness of breath, chest pain, or new or worse cough.

Intestinal problems (colitis) that can lead to tears or holes in your intestine. Signs and symptoms of colitis may include diarrhea or more 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, including hepatitis. Signs and symptoms of liver problems may include yellowing of your skin or the whites of your eyes, nausea or vomiting, pain on the right side of your stomach area (abdomen), dark urine, or bleeding or bruising more easily than normal.

Hormone gland problems (especially the thyroid, pituitary, adrenal glands, and pancreas). Signs and symptoms that your hormone glands are not working properly may include rapid heartbeat, weight loss or weight gain, increased sweating, feeling more hungry or thirsty, urinating more often than usual, hair loss, feeling cold, constipation, your voice gets deeper, muscle aches, feeling very weak, dizziness or fainting, or headaches that will not go away or unusual headache.

Kidney problems, including nephritis and kidney failure. Signs of kidney problems may include change in the amount or color of your urine.

Skin problems. Signs of skin problems may include rash, itching, blisters, peeling or skin sores, or painful sores or ulcers in your mouth or in your nose, throat, or genital area.

Problems in other organs. Signs and symptoms of these problems may include changes in eyesight; severe or persistent muscle or joint pains; severe muscle weakness; low red blood cells (anemia); swollen lymph nodes, rash or tender lumps on skin, cough, shortness of breath, vision changes, or eye pain (sarcoidosis); confusion, fever, muscle weakness, balance problems, nausea, vomiting, stiff neck, memory problems, or seizures (encephalitis); and shortness of breath, irregular heartbeat, feeling tired, or chest pain (myocarditis).

Infusion (IV) reactions that can sometimes be severe and life-threatening. Signs and symptoms of infusion reactions may include chills or shaking, shortness of breath or wheezing, itching or rash, flushing, dizziness, fever, or feeling like passing out.

Rejection of a transplanted organ. People who have had an organ transplant may have an increased risk of organ transplant rejection if they are treated with KEYTRUDA.

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 severe and can lead to death. These complications may happen if you underwent transplantation either before or after being treated with KEYTRUDA. Your doctor will monitor you for the following signs and symptoms: skin rash, liver inflammation, abdominal pain, and diarrhea.

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

Before you receive KEYTRUDA, tell your doctor if you have immune system problems such as Crohn’s disease, ulcerative colitis, or lupus; have had an organ transplant or plan to have or have had a bone marrow (stem cell) transplant that used donor stem cells (allogeneic); have lung or breathing problems; have liver problems; or have any other medical problems.

If you are pregnant or plan to become pregnant, tell your doctor. KEYTRUDA can harm your unborn baby. If you are able to become pregnant, your doctor will give you a pregnancy test before you start treatment. Use effective birth control during treatment and for at least 4 months after the final dose of KEYTRUDA. Tell your doctor right away if you think you may be pregnant or you become pregnant during treatment with KEYTRUDA.

If you are breastfeeding or plan to breastfeed, tell your doctor. It is not known if KEYTRUDA passes into your breast milk. Do not breastfeed during treatment with KEYTRUDA and for 4 months after your final dose of KEYTRUDA.

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

In children, feeling tired, vomiting and stomach-area (abdominal) pain, and increased levels of liver enzymes and decreased levels of salt (sodium) in the blood are more common than in adults.

These are not all the possible side effects of KEYTRUDA. Tell your doctor if you have any side effect that bothers you or that does not go away. For more information, ask your doctor or pharmacist.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
