Cemiplimab monotherapy as first-line treatment of patients with brain metastases from advanced non-small cell lung cancer with programmed cell death-ligand 1 ≥50.
Trial report in Cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03088540 (A Global, Randomised, Phase 3, Open-label Study of REGN2810), which is not on this map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it

Abstract
backgroundIn the phase 3 EMPOWER-Lung 1 study, first-line cemiplimab monotherapy provided significant survival benefit versus chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) with programmed cell death-ligand 1 (PD-L1) ≥50%. This exploratory subgroup analysis investigated the clinical outcomes of cemiplimab treatment in patients with advanced NSCLC with brain metastases.
methodsPatients with advanced NSCLC were randomized (1:1) to cemiplimab 350 mg every 3 weeks or four cycles of platinum doublet chemotherapy (NCT03088540). Patients with symptomatic radiotherapy-treated brain metastases were eligible to enroll. Of the 565 patients with confirmed PD-L1 expression ≥50%, 69 (12%) had brain metastases at baseline.
resultsPatients with brain metastases who received cemiplimab had a median overall survival (OS) of 52.4 months compared with 20.7 months for those who received chemotherapy (hazard ratio [HR], 0.40; p = .0031) and a median progression-free survival (PFS) of 12.5 versus 5.3 months (HR, 0.33; p = .0002), respectively. Patients without brain metastases had a median OS of 24.3 months with cemiplimab versus 12.5 months with chemotherapy (HR, 0.63; p < .0001); their median PFS was 6.5 months versus 5.2 months (HR, 0.55; p < .0001), respectively. Cemiplimab was associated with a significant improvement in global health status/quality of life in all patients, including those with brain metastases. The cemiplimab safety profile was generally similar in all patients.
conclusionsIn patients with advanced NSCLC with PD-L1 ≥50%, first-line cemiplimab monotherapy improved survival and patient-reported outcomes over chemotherapy for those who received prior radiotherapy for symptomatic brain metastases.
