    Background We aimed to examine cemiplimab, a programmed cell death 1 inhibitor, in the first-line treatment of advanced non-small-cell lung cancer with programmed cell death ligand 1 (PD-L1) of at least 50%. Methods In EMPOWER-Lung 1, a multicentre, open-label, global, phase 3 study, eligible patients recruited in 138 clinics from 24 countries (aged >= 18 years with histologically or cytologically confirmed advanced non-small-cell lung cancer, an Eastern Cooperative Oncology Group performance status of 0-1; never-smokers were ineligible) were randomly assigned (1:1) to cemiplimab 350 mg every 3 weeks or platinum-doublet chemotherapy. Crossover from chemotherapy to cemiplimab was allowed following disease progression. Primary endpoints were overall survival and progression-free survival per masked independent review committee. Primary endpoints were assessed in the intention-to-treat population and in a prespecified PD-L1 of at least 50% population (per US Food and Drug Administration request to the sponsor), which consisted of patients with PD-L1 of at least 50% per 22C3 assay done according to instructions for use. Adverse events were assessed in all patients who received at least one dose of the assigned treatment. This study is registered with ClinicalTrials.gov, NCT03088540 and is ongoing. Findings Between June 27, 2017 and Feb 27, 2020, 710 patients were randomly assigned (intention-to-treat population). In the PD-L1 of at least 50% population, which consisted of 563 patients, median overall survival was not reached (95% CI 17.9-not evaluable) with cemiplimab (n=283) versus 14.2 months (11.2-17.5) with chemotherapy (n=280; hazard ratio [HR] 0.57 [0.42-0.77]; p=0.0002). Median progression-free survival was 8.2 months (6.1-8.8) with cemiplimab versus 5.7 months (4.5-6.2) with chemotherapy (HR 0.54 [0.43-0.68]; p<0.0001). Significant improvements in overall survival and progression-free survival were also observed with cemiplimab in the intention-to-treat population despite a high crossover rate (74%). Grade 3-4 treatment-emergent adverse events occurred in 98 (28%) of 355 patients treated with cemiplimab and 135 (39%) of 342 patients treated with chemotherapy. Interpretation Cemiplimab monotherapy significantly improved overall survival and progression-free survival compared with chemotherapy in patients with advanced non-small-cell lung cancer with PD-L1 of at least 50%, providing a potential new treatment option for this patient population.

    Patient-Reported Outcomes with Cemiplimab Monotherapy for First-Line Treatment of Advanced Non-Small Cell Lung Cancer with PD-L1 Of >= 50%: The EMPOWER-Lung 1 Study
    (2023) Gumus, Mahmut; Chen, Chieh-, I; Ivanescu, Cristina; Kilickap, Saadettin; Bondarenko, Igor; Ozguroglu, Mustafa; Gogishvili, Miranda; Turk, Haci M.; Cicin, Irfan; Harnett, James; Mastey, Vera; Naumann, Ulrike; Reaney, Matthew; Konidaris, Gerasimos; Sasane, Medha; Brady, Keri J. S.; Li, Siyu; Gullo, Giuseppe; Rietschel, Petra; Sezer, Ahmet; 36308296
    Background In the EMPOWER-Lung 1 trial (, NCT03088540), cemiplimab conferred longer survival than platinum-doublet chemotherapy for advanced non-small cell lung cancer (NSCLC) with programmed cell death-ligand 1 (PD-L1) >= 50%. Patient-reported outcomes were evaluated among trial participants. Methods Adults with NSCLC and Eastern Cooperative Oncology Group performance status 0 to 1 were randomly assigned cemiplimab 350 mg every 3 weeks or platinum-doublet chemotherapy. At baseline and day 1 of each treatment cycle, patients were administered the European Organization for Research and Treatment of Cancer Quality of Life-Core 30 (QLQ-C30) and Lung Cancer Module (QLQ-LC13) questionnaires. Mixed-model repeated measures analysis estimated overall change from baseline for PD-L1 >= 50% and intention-to-treat populations. Kaplan-Meier analysis estimated time to definitive deterioration. Results In PD-L1 >= 50% patients (cemiplimab, n = 283; chemotherapy, n = 280), baseline QLQ-C30 and QLQ-LC13 scores showed moderate-to-high functioning and low symptom burden. Change from baseline favored cemiplimab on global health status/quality of life (GHS/QOL), functioning, and most symptom scales. Risk of definitive deterioration across functioning scales was reduced versus chemotherapy; hazard ratios were 0.48 (95% CI, 0.32-0.71) to 0.63 (95% CI, 0.41-0.96). Cemiplimab showed lower risk of definitive deterioration for disease-related (dyspnea, cough, pain in chest, pain in other body parts, fatigue) and treatment-related symptoms (peripheral neuropathy, alopecia, nausea/vomiting, appetite loss, constipation, diarrhea) (nominal p < .05). Results were similar in the intention-to-treat population. Conclusions Results support cemiplimab for first-line therapy of advanced NSCLC from the patient's perspective. Improved survival is accompanied by improvements versus platinum-doublet chemotherapy in GHS/QOL and functioning and reduction in symptom burden.
