Advanced cervical cancer
KEYTRUDA or KEYTRUDA QLEX with chemotherapy and radiation therapy (FIGO 2014 Stage 3 to 4A cervical cancer)
Understanding treatment and clinical trial results

Treatment overview for KEYTRUDA and KEYTRUDA QLEX
KEYTRUDA and KEYTRUDA QLEX are prescription medicines used to treat a kind of cancer called cervical cancer. Each may be used with chemotherapy and radiation therapy when:
- your cervical cancer has spread nearby to the lower part of your vagina or to pelvic organs
- has affected your kidneys (Stage 3 to 4A cervical cancer based on FIGO 2014 classification)
It is not known if KEYTRUDA and KEYTRUDA QLEX are safe and effective for this use in children.

KEYTRUDA or KEYTRUDA QLEX may be part of your treatment plan
No one is prepared to hear the word cancer. Learning more about your diagnosis and treatment can make a difference. The information below can help you understand how your treatment works. Remember, you have a voice in your care.
KEYTRUDA or KEYTRUDA QLEX with chemotherapy and radiation therapy helps fight cancer cells
KEYTRUDA and KEYTRUDA QLEX are a type of therapy called immunotherapy. Immunotherapy is different from chemotherapy. Instead of attacking cancer cells directly, immunotherapy helps your immune system do what it is designed to do: find and fight cancer cells. KEYTRUDA and KEYTRUDA QLEX 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.
Chemotherapy uses a drug to attack and kill quickly-growing cells directly. When chemotherapy is used with radiation therapy, it helps to sensitize the cancer cells to the radiation.
Radiation therapy uses high-energy beams from an external source or ionizing radiation from an internal source to target and destroy cancer cells.
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.

With KEYTRUDA in combination with chemotherapy and radiation therapy, you may have an FDA-approved option if your cervical cancer has spread nearby to the lower part of your vagina or to pelvic organs or has affected your kidneys (Stage 3 to 4A cervical cancer based on FIGO 2014 classification)
FIGO = International Federation of Gynecology and Obstetrics.
- Among 1,060 people in a clinical trial, 599 people had FIGO 2014 Stage 3 to 4A cervical cancer and had not previously received any surgery, radiation, or systemic therapy for cervical cancer.
- Among those 599 people, 295 received 200 mg of KEYTRUDA every 3 weeks with chemotherapy and radiation therapy followed by 400 mg of KEYTRUDA every 6 weeks, and 304 people received placebo† with chemotherapy and radiation therapy.
- The chemotherapy medicine used in this trial was cisplatin
†Placebo = an inactive treatment given instead of an active treatment.
At time of patient follow-up, in people with FIGO 2014 Stage 3 to 4A cervical cancer, KEYTRUDA in combination with chemotherapy and radiation therapy was shown to reduce the risk of cancer spreading, growing, or getting worse by 41% compared to placebo with chemotherapy and radiation therapy
79% (234 of 295) of people receiving KEYTRUDA in combination with chemotherapy and radiation therapy compared to 70% (214 of 304) of people receiving placebo with chemotherapy and radiation therapy were alive at the time of patient follow-up.
Cancer did not progress in 79% (234 of 295) of people receiving KEYTRUDA in combination with chemotherapy and radiation therapy compared to 69% (210 of 304) of people receiving placebo with chemotherapy and radiation therapy.
Understanding different types of results
There’s a lot to take in when learning about your diagnosis. And several terms your doctor may use to talk about your treatment goals are important to understand.
Time without the cancer spreading, growing, or getting worse
Your doctor may measure the amount of time the cancer is not getting worse or spreading. This is called progression-free survival (PFS).
