Advanced endometrial cancer
CLINICAL TRIAL RESULTS

KEYTRUDA or KEYTRUDA QLEX with chemotherapy then continued alone for certain types of endometrial cancer that has spread (advanced) or if your cancer has returned
KEYTRUDA and KEYTRUDA QLEX are prescription medicines used to treat:
- a kind of uterine cancer called advanced endometrial carcinoma.
- Each may be used with the chemotherapy medicines carboplatin and paclitaxel, and then may be used alone, in adults:
- when your cancer has spread (advanced), or
- if your cancer has returned.
- Each may be used with the chemotherapy medicines carboplatin and paclitaxel, and then may be used alone, in adults:
It is not known if KEYTRUDA and KEYTRUDA QLEX are safe and effective for this use in children.
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.
KEYTRUDA with the chemotherapy medicines carboplatin and paclitaxel, followed by KEYTRUDA alone, was shown to reduce the risk of cancer spreading, growing, or getting worse compared to placebo with the chemotherapy medicines carboplatin and paclitaxel followed by placebo alone
In a clinical trial, KEYTRUDA and chemotherapy† followed by KEYTRUDA alone was studied in adults who were diagnosed with primary advanced endometrial cancer, which is when the cancer has spread, or whose cancer was recurrent, meaning it had returned. These adults hadn’t received prior treatment or had received prior adjuvant (a-juh-vunt) chemotherapy, which is used after surgery and may help lower the chance of cancer coming back, more than 12 months ago.
- Among 810 adults with advanced or recurrent endometrial cancer, 588 (73%) had cancer that was pMMR, and 222 (27%) had cancer that was dMMR.
- Among all participants, 404 adults received KEYTRUDA 200 mg every 3 weeks with chemotherapy† followed by KEYTRUDA 400 mg alone every 6 weeks, while 406 adults received placebo with chemotherapy* followed by placebo alone.
pMMR = mismatch repair proficient. This occurs when the DNA repair system is working correctly.
dMMR = mismatch repair deficient. This occurs when the DNA repair system is not working correctly, which may lead to a buildup of errors in the genetic sequence.
Placebo = an inactive treatment given instead of an active treatment.
†The chemotherapy medicines used in this trial were carboplatin and paclitaxel.
At the time of patient follow-up, for adults whose cancer was pMMR:
KEYTRUDA with the chemotherapy medicines carboplatin and paclitaxel, followed by KEYTRUDA alone, was shown to reduce the risk of cancer spreading, growing, or getting worse by 40% compared to placebo with the chemotherapy medicines carboplatin and paclitaxel, followed by placebo alone.
Cancer did not progress in 69% of adults (203 of 294) receiving KEYTRUDA with the chemotherapy medicines carboplatin and paclitaxel followed by KEYTRUDA alone compared to 58% of adults (170 of 294) receiving placebo with the chemotherapy medicines carboplatin and paclitaxel followed by placebo alone.
At the time of patient follow-up, for adults whose cancer was dMMR:
KEYTRUDA with the chemotherapy medicines carboplatin and paclitaxel, followed by KEYTRUDA alone, was shown to reduce the risk of cancer spreading, growing, or getting worse by 70% compared to placebo with the chemotherapy medicines carboplatin and paclitaxel, followed by placebo alone.
Cancer did not progress in 76% of adults (84 of 110) receiving KEYTRUDA with the chemotherapy medicines carboplatin and paclitaxel followed by KEYTRUDA alone compared to 49% of adults (55 of 112) receiving placebo with the chemotherapy medicines carboplatin and paclitaxel followed by placebo alone.
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).
