JEMPERLI was studied across multiple tumor types

For people with dMMR* solid tumors that have returned or spread (advanced cancer) AND have progressed during or after treatment AND have no satisfactory treatment options. This use is approved based on how many patients responded to treatment and how long they responded. Studies are ongoing to confirm the clinical benefit of JEMPERLI for this use.

*dMMR stands for “mismatch repair deficient.” It describes cancers that have an MMR system that is not working properly to correct errors in the genes. dMMR is an important biomarker in endometrial cancer.

How JEMPERLI may help

Researchers studied how JEMPERLI works in 209 people with dMMR solid tumors that had returned or spread (advanced cancer) and had progressed during or after treatment and had no satisfactory treatment options.

These people had a variety of dMMR tumor types, including:

  • Endometrial cancer
  • Colorectal cancer
  • Small intestinal cancer
  • Gastric cancers
  • Pancreatic carcinoma
  • Biliary neoplasm
  • Liver cancer
  • Ovarian cancer
  • Adrenal cortical
  • Breast cancer
  • Esophageal cancer
  • Malignant neoplasm of the female genitals
  • Pleural
  • Renal cell carcinoma
  • Unknown origin

If you have a dMMR solid tumor, talk to your doctor about treatment options.

Many study participants receiving JEMPERLI alone for dMMR solid tumors had their tumors disappear or partially shrink

This does not always mean that the cancer has been cured.

Many participants in the study had a continued response with JEMPERLI

95% of study participants who responded to treatment kept their response for6 MONTHS OR LONGER

In study participants with tumors that responded to treatment, the duration of their responses (DOR) ranged from 2.6 to 35.8+ months with a median DOR of 34.7 months. Median (MEE-dee-un) is the middle value in a set of measurements. DOR is the amount of time before cancer began growing or spreading again for study participants who responded to treatment. Median follow-up time was 17.5 months. Follow-up time is the length of time a person's health has been monitored.

+ means still responding at last follow-up visit.

You may experience side effects from JEMPERLI

JEMPERLI is a medicine that may treat certain cancers by working with your immune system. JEMPERLI 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 anytime during treatment or even after your treatment has ended.

9% of study participants stopped taking JEMPERLI completely and 23% had their treatment interrupted due to side effects.

  • 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 JEMPERLI. Your healthcare provider will monitor you for these complications.

Getting medical treatment right away may help keep these problems from becoming more serious.

Your healthcare provider may also need to delay or completely stop treatment with JEMPERLI, if you have severe side effects.

The most common side effects of JEMPERLI when given alone for dMMR solid tumors include tiredness and weakness, low red blood cell count (anemia), diarrhea, nausea, constipation, and vomiting.

Good to know

  • Your healthcare provider will decide how many treatments you need
  • Your healthcare provider will check you for side effects
  • If you miss an appointment, it is important to reschedule as soon as possible

Understanding immunotherapy

JEMPERLI is not chemotherapy or radiation. It is an immunotherapy (IH-myoo-noh-THAYR-uh-pee), which means it is designed to work with the body’s immune system to find and attack cancer cells.

Here's how JEMPERLI works:

Related FAQs

  • How many people participated in the clinical trial of JEMPERLI alone for advanced or returned dMMR solid tumors?

    The clinical trial that studied the effectiveness of JEMPERLI alone for dMMR solid tumors included 209 people. They had dMMR solid tumors that had returned or spread (advanced cancer) and had progressed during or after treatment and had no satisfactory treatment options.

    The clinical trial also studied the risks and side effects of JEMPERLI alone in 267 people who had advanced or returned dMMR solid tumors.

    Studies are ongoing to confirm the clinical benefit of JEMPERLI for this use.

  • What is a biomarker?

    A biomarker (BY-oh-MAR-ker) is a molecule found in the tissues or fluids of your body that shows if a condition, process, or disease is normal or abnormal. Solid tumors may have a biomarker known as dMMR (mismatch repair deficiency). Testing for this biomarker provides important information about your cancer and may help your doctor decide what treatment options, including JEMPERLI, may be right for you.

  • Does GSK offer support and access resources for people being treated with JEMPERLI?

    Yes. Together with GSK Oncology is a free patient resource program for you and your doctor to help with access and financial issues related to JEMPERLI. To learn whether you are eligible, visit Together with GSK Oncology.
