Trial report in Lancet (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. It is linked to 3 registered trials, which are not on this map. Cited by 109 papers, 11 of them syntheses that pooled it.
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
backgroundIvonescimab is a bispecific antibody against programmed cell death protein 1 and vascular endothelial growth factor, yielding promising clinical outcomes for patients with advanced non-small cell lung cancer in early-phase studies. We compared the efficacy and safety of ivonescimab with pembrolizumab in patients with programmed cell death ligand-1 (PD-L1)-positive advanced non-small cell lung cancer.
methodsHARMONi-2 is a randomised, double-blind, phase 3 trial across 55 hospitals in China. Eligible patients were aged 18 years or older and had locally advanced or metastatic PD-L1-positive non-small cell lung cancer without sensitising epidermal growth factor receptor mutations or anaplastic lymphoma kinase translocations and an Eastern Cooperative Oncology Group performance-status of 0 or 1. Patients were randomly assigned (1:1) to receive 20 mg/kg ivonescimab or 200 mg pembrolizumab intravenously every 3 weeks. Randomisation was stratified by histology, clinical stage, and PD-L1 expression. The primary endpoint was progression-free survival (PFS) assessed by a masked independent radiographic review committee per RECIST v1.1 in the intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT05499390; recruitment is complete, with the trial ongoing and final analysis to be reported later.
findingsBetween Nov 9, 2022, and Aug 26, 2023, 398 (45%) of 879 screened patients were randomly assigned to receive ivonescimab (n=198) or pembrolizumab (n=200). At the preplanned interim analysis, median PFS was significantly longer with ivonescimab than with pembrolizumab (11·1 vs 5·8 months; stratified hazard ratio [HR] 0·51 [95% CI 0·38-0·69]; one-sided p<0·0001). The PFS benefit of ivonescimab over pembrolizumab was broadly consistent within prespecified subgroups, including patients with PD-L1 tumour proportion score (TPS) 1-49% (HR 0·54 [95% CI 0·37-0·78]) and PD-L1 TPS of 50% of higher (HR 0·48 [0·29-0·79]). Grade 3 or higher treatment-related adverse events occurred in 58 (29%) patients with ivonescimab and 31 (16%) patients with pembrolizumab. Immune-related adverse events of grade 3 or higher were observed in 14 (7%) of 197 patients on ivonescimab and 16 (8%) of 199 patients on pembrolizumab. Ivonescimab demonstrated a manageable safety profile in patients with both squamous and non-squamous non-small cell lung cancer. In patients with squamous cell carcinoma, grade 3 or higher treatment-related adverse events were comparable between the two groups.
interpretationIvonescimab significantly improved PFS compared with pembrolizumab in previously untreated patients with advanced PD-L1 positive non-small cell lung cancer. Therefore, ivonescimab might represent another treatment option in the first-line setting for PD-L1-positive advanced non-small cell lung cancer.
