Non–small cell lung cancer (NSCLC)
CLINICAL TRIAL RESULTS

KEYTRUDA or KEYTRUDA QLEX used alone as a first treatment and a chemotherapy-free option for advanced NSCLC
KEYTRUDA and KEYTRUDA QLEX are prescription medicines used to treat:
- a kind of lung cancer called non–small cell lung cancer (NSCLC)
- Each may be used alone as your first treatment when your lung cancer has not spread outside your chest (stage III) and you cannot have surgery or chemotherapy with radiation, or your NSCLC has spread to other areas of your body (advanced NSCLC), and your tumor tests positive for “PD‑L1” and does not have an abnormal “EGFR” or “ALK” gene.
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, certain patients with advanced non–small cell lung cancer received either KEYTRUDA QLEX or pembrolizumab. 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 pembrolizumab for each of the approved uses.
In a clinical trial, at the time of patient follow-up, KEYTRUDA used alone as a first treatment was proven to help patients live longer compared to chemotherapy
A clinical trial compared patients with advanced non–small cell lung cancer who received KEYTRUDA with those who received chemotherapy containing platinum. All patients in the trial had no previous drug treatment and did not have an abnormal EGFR or ALK gene. 154 patients received 200 mg of KEYTRUDA every 3 weeks, and 151 patients received chemotherapy.
All patients in this clinical trial tested positive for the biomarker PD-L1 at a level of 50% or more.More patients lived longer
More patients saw tumors shrink
KEYTRUDA reduced the risk of disease progression by 50% compared to chemotherapy
KEYTRUDA reduced the risk of cancer spreading, growing, or getting worse by 50% compared to chemotherapy.
Half of the patients on KEYTRUDA were alive without their cancer spreading, growing, or getting worse at 10.3 months, compared to 6 months for patients on chemotherapy. Cancer did not progress in 53% of patients receiving KEYTRUDA compared to 23% of patients receiving chemotherapy.
In another clinical trial, at the time of patient follow-up, KEYTRUDA, used alone as a first treatment, helped patients live longer compared to chemotherapy
This clinical trial compared patients with advanced non–small cell lung cancer who received KEYTRUDA with those who received chemotherapy containing platinum. All patients in the trial had no previous drug treatment, and did not have an abnormal EGFR or ALK gene. 637 patients received 200 mg of KEYTRUDA every 3 weeks, and 637 patients received chemotherapy.
All patients in this clinical trial tested positive for biomarker PD-L1 at a level of 1% or more.The results of the trial are shown below in 2 groups: the first group are patients who tested positive for a high level of PD-L1 (≥50%), and the second group are patients who tested positive for PD-L1 (≥1%).
Results in the group of patients whose tumors had high levels of PD-L1 (≥50%)
More patients lived longer
Patients treated with KEYTRUDA and patients treated with chemotherapy both saw tumors shrink
Disease progression
In the clinical trial, half the patients treated with KEYTRUDA were alive without their cancer spreading, growing, or getting worse at 6.9 months compared to 6.4 months for patients treated with chemotherapy. Cancer did not progress in 26% of the patients receiving KEYTRUDA compared to 22% of patients treated with chemotherapy.
Results for all patients in the trial (tumor PD-L1 level ≥1%)
More patients lived longer
Patients treated with KEYTRUDA and patients treated with chemotherapy both saw tumors shrink
Disease progression
In the clinical trial, half the patients treated with KEYTRUDA were alive without their cancer spreading, growing, or getting worse at 5.4 months compared to 6.5 months for patients treated with chemotherapy. Cancer did not progress in 20% of the patients receiving KEYTRUDA compared to 21% of patients treated with chemotherapy.
