Treatment overview for KEYTRUDA and KEYTRUDA QLEX
Immunotherapy may be an option if you have advanced esophageal cancer or certain GEJ carcinomas
Esophageal cancer is when cells in the lining of the esophagus begin to grow out of control. As more cancer cells develop, they can spread to other areas of the body. When cancer has spread in the esophagus, it’s known as advanced esophageal cancer. The GEJ is where the esophagus joins the stomach. When cancer has spread in the GEJ, it’s known as advanced GEJ carcinoma.
Always talk to your doctor about your treatment options. If you have advanced esophageal cancer or certain GEJ carcinomas, your doctor may consider:
KEYTRUDA or KEYTRUDA QLEX with chemotherapy as your first treatment
KEYTRUDA or KEYTRUDA QLEX may be used in combination with platinum- and fluoropyrimidine-based chemotherapy medicines as your first treatment when your esophageal cancer or certain GEJ carcinomas cannot be cured by surgery or a combination of chemotherapy and radiation therapy, and when your tumor tests positive for “PD-L1.”
It is not known if KEYTRUDA and KEYTRUDA QLEX are safe and effective for this use in children.
KEYTRUDA or KEYTRUDA QLEX used alone for your advanced esophageal squamous cell carcinoma
KEYTRUDA or KEYTRUDA QLEX may be used for your esophageal cancer or certain GEJ carcinomas when you have received one or more types of treatment, and it did not work or it is no longer working, and your tumor is a type called “squamous,” and your tumor tests positive for “PD-L1.”
It is not known if KEYTRUDA and KEYTRUDA QLEX are safe and effective for this use in children.
Talk to your doctor to see if KEYTRUDA may be an option for you after chemotherapy.
Understanding the need for biomarker testing
Everyone’s advanced esophageal squamous cell carcinoma 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. Talk to your doctor to see if a PD-L1 biomarker test is right for you.
Clinical Trial Results
Based on a KEYTRUDA QLEX study, the results were similar to KEYTRUDA
The effectiveness of KEYTRUDA QLEX for its approved uses has been shown based on data from clinical trials. In one of these trials, patients with a different type of cancer* received either KEYTRUDA QLEX or KEYTRUDA. This study showed these groups had similar amounts of medicine in their blood, with no notable differences in how well the medicines worked or in their safety. The effectiveness of KEYTRUDA QLEX is also based on clinical trials of KEYTRUDA for each of the approved uses.
*Advanced non–small cell lung cancer.
As a first treatment, KEYTRUDA + chemotherapy has been proven to help people with advanced esophageal or GEJ cancer live longer compared to chemotherapy alone
A total of 749 people with advanced esophageal cancer, or advanced GEJ carcinoma in a particular location, that could not be removed by surgery or treated with chemotherapy and radiation, were enrolled in a clinical trial. Among the 749 people in the trial, 647 (86% of patients) had tumors expressing PD-L1 (CPS ≥1). Of these PD-L1 positive patients, a total of 320 adults received 200 mg of KEYTRUDA every 3 weeks with chemotherapy, and 327 adults received chemotherapy alone.
More people taking KEYTRUDA with chemotherapy lived longer compared to people taking chemotherapy alone
KEYTRUDA + chemotherapy reduced the risk of disease progression by 38% compared to chemotherapy alone
Half of people receiving KEYTRUDA with chemotherapy were alive without their cancer spreading, growing, or getting worse at 6.3 months, compared to 5.7 months for people treated with chemotherapy alone. Cancer did not progress in 21% (68 out of 320) of people receiving KEYTRUDA with chemotherapy compared to 11% (36 out of 327) of people receiving chemotherapy alone.
More people saw tumors shrink
Duration of responses
The median response rate was 8.6 months for people taking KEYTRUDA with chemotherapy (1.2+ to 31.0+ months), compared to 5.8 months for people taking chemotherapy alone (1.5+ to 25.0+ months).
