Neoadjuvant retlirafusp alfa (anti-PD-L1/TGF-β bifunctional fusion protein) with or without chemotherapy in unresectable stage III non-small cell lung cancer: updated results from the phase 2 TRAILBLAZER trial.
Trial report in Signal transduction and targeted therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04580498 (An Open-label, Multicenter Phase II Clinical Trial of SHR-1701 With or Without Chemotherapy in the Treatment of Unresectable Stage III Non-small Cell Lung Cancer), which is not on this map.

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.

Abstract
TRAILBLAZER is a proof-of-concept phase 2 study (ClinicalTrials.gov, NCT04580498) of neoadjuvant retlirafusp alfa (an anti-PD-L1/TGF-β bifunctional agent) in unresectable stage III non-small cell lung cancer (NSCLC) not harboring EGFR or ALK alterations. During induction, retlirafusp alfa was administered either with chemotherapy or as monotherapy, followed by surgery or radiotherapy as assessed by a local multidisciplinary team and consolidation retlirafusp alfa. Patients without high PD-L1 expression were allocated to retlirafusp alfa plus chemotherapy (arm A; n = 88); patients with high PD-L1 expression were randomly allocated at a 1:1 ratio to retlirafusp alfa combination (arm B; n = 9) or monotherapy (arm C; n = 10). In this updated analysis (data cutoff, March 24, 2025), the median follow-up was 39.4 months. The event-free survival (EFS) rate at 3 years was 50.5% (95% CI 39.0-61.0) in arm A + B and 77.1% (34.5-93.9) in arm C; the corresponding overall survival (OS) rates at 3 years were 68.3% (95% CI 57.5-77.0) and 87.5% (38.7-98.1), respectively. Among 27 patients who underwent surgery, the 3-year EFS and OS rates were 69.5% (95% CI 48.1-83.5) and 84.9% (64.5-94.0), respectively, versus 50.8% (36.5-63.4) and 70.4% (56.7-80.5), respectively, in radiotherapy-treated patients. The safety data were consistent with those in a previous report. With extended follow-up, the study regimen showed sustained survival benefits with no new safety signals. Patients who underwent surgery after induction treatment achieved clinically meaningful survival gains. Our findings support the use of neoadjuvant immunotherapy with a response-adapted surgical strategy as a promising approach for unresectable stage III NSCLC.
