Abstract

BACKGROUND: First-line therapy for advanced non-small-cell lung cancer (NSCLC) that lacks targetable mutations is platinum-based chemotherapy. Among patients with a tumor proportion score for programmed death ligand 1 (PD-L1) of 50% or greater, pembrolizumab has replaced cytotoxic chemotherapy as the first-line treatment of choice. The addition of pembrolizumab to chemotherapy resulted in significantly higher rates of response and longer progression-free survival than chemotherapy alone in a phase 2 trial. METHODS: In this double-blind, phase 3 trial, we randomly assigned (in a 2:1 ratio) 616 patients with metastatic nonsquamous NSCLC without sensitizing EGFR or ALK mutations who had received no previous treatment for metastatic disease to receive pemetrexed and a platinum-based drug plus either 200 mg of pembrolizumab or placebo every 3 weeks for 4 cycles, followed by pembrolizumab or placebo for up to a total of 35 cycles plus pemetrexed maintenance therapy. Crossover to pembrolizumab monotherapy was permitted among the patients in the placebo-combination group who had verified disease progression. The primary end points were overall survival and progression-free survival, as assessed by blinded, independent central radiologic review. RESULTS: After a median follow-up of 10.5 months, the estimated rate of overall survival at 12 months was 69.2% (95% confidence interval [CI], 64.1 to 73.8) in the pembrolizumab-combination group versus 49.4% (95% CI, 42.1 to 56.2) in the placebo-combination group (hazard ratio for death, 0.49; 95% CI, 0.38 to 0.64; P<0.001). Improvement in overall survival was seen across all PD-L1 categories that were evaluated. Median progression-free survival was 8.8 months (95% CI, 7.6 to 9.2) in the pembrolizumab-combination group and 4.9 months (95% CI, 4.7 to 5.5) in the placebo-combination group (hazard ratio for disease progression or death, 0.52; 95% CI, 0.43 to 0.64; P<0.001). Adverse events of grade 3 or higher occurred in 67.2% of the patients in the pembrolizumab-combination group and in 65.8% of those in the placebo-combination group. CONCLUSIONS: In patients with previously untreated metastatic nonsquamous NSCLC without EGFR or ALK mutations, the addition of pembrolizumab to standard chemotherapy of pemetrexed and a platinum-based drug resulted in significantly longer overall survival and progression-free survival than chemotherapy alone.

  • Many of the studies used ICIs as monotherapy in a heavily pretreated population, whereas current standard first-line therapy often includes combination ICIs or ICI with chemotherapy for multiple tumor types.

    “Third, many of these studies utilized ICIs as monotherapy in a heavily pretreated population whereas current standard first-line therapy often includes a combination of ICIs or ICI with chemotherapy for multiple tumor types (35–40).”
  • KRAS mutation-positive patients derived benefit in both PFS and OS from pembrolizumab plus chemotherapy versus platinum doublet therapy alone as first-line therapy for metastatic NSCLC.

    “KRAS mutation-positive patients derived benefit in both PFS and OS from the combination of pembrolizumab plus chemotherapy as opposed to platinum doublet therapy alone as first-line therapy for patients with metastatic NSCLC66.”
  • Addition of pembrolizumab significantly prolongs survival of NSCLC patients.

    “Importantly, two remarkable phase III trials (KEYNOTE-189 and KEYNOTE-407) demonstrated that addition of pembrolizumab (Keytruda, anti-PD1) could significantly prolong the survival of NSCLC patients (45, 97).”

  • Pembrolizumab in combination with chemotherapy is approved for metastatic, non-squamous NSCLC and for squamous lung carcinoma excluding EGFR or ALK mutations.

    “The promising results from these studies have led to the approval of pembrolizumab in combination with chemotherapy (carboplatin-pemetrexed) for metastatic, non-squamous NSCLC, and the approval of pembrolizumab in combination with chemotherapy (carboplatin and Taxol) for patients with squamous lung carcinoma, excluding those carrying EGFR or ALK mutations.”

  • Phase III data show overall survival and/or progression-free survival benefit for immune checkpoint therapy plus chemotherapy in non-small cell lung cancer, small cell lung cancer, triple-negative breast cancer, bladder cancer, and head and neck squamous cell carcinoma.

    “Toward this end, combinations of ICTs with concurrent and/or sequential chemotherapy are under extensive investigation, with phase III clinical data demonstrating overall survival and/or progression-free survival benefi t in NSCLC ( 63-66 ), small cell lung cancer ( 51,52 ), triple-negative breast cancer ( 67 ), bladder cancer ( 53 ), and head and neck squamous cell carcinoma ( 68 ).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
