Safety and efficacy of zolbetuximab plus chemotherapy for claudin 18 isoform 2-positive advanced gastric cancer: initial report of real-world experience.
Article in Journal of cancer research and clinical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study evaluated the safety and preliminary efficacy of zolbetuximab plus chemotherapy in patients with claudin 18 isoform 2 (CLDN18.2)-positive advanced gastric cancer (AGC).
methodsThis single-institutional retrospective study enrolled patients with HER2-negative CLDN18.2-positive AGC who were treated with zolbetuximab plus chemotherapy between July 2024 and August 2025.
resultsThe cohort included 50 patients with a median age of 63 years (range 30-83; 44% male). The primary tumor location was the stomach in 86% of the patients. Meanwhile, 26% of the patients underwent prior gastrectomy. The PD-L1 combined positive score was < 5 in 87% of patients. Among 24 patients with measurable lesions at baseline, the objective response and disease control rates were 66.7% and 87.5%, respectively. After median follow-up of 7.3 months, median progression-free survival and the duration of response were 6.7 [95% confidence interval (CI) 5.3-10.7] and 6.7 months (95% CI 4.7-10.2), respectively. Grade ≥ 3 treatment-emergent adverse events occurred in 62% of the patients, most commonly hypoalbuminemia (22%), neutrophil count decreased (22%) and anorexia (12%). Subsequent treatment was received by 83% of the patients.
conclusionsZolbetuximab plus chemotherapy was administered to real-world patients with CLDN18.2-positive AGC with acceptable safety profiles and showed preliminary antitumor efficacy. Nevertheless, some adverse events warrant careful monitoring.
