Phase Ia/Ib Study of Afatinib with Capecitabine in Patients with Refractory Solid Tumors and Pancreaticobiliary Cancers.
Article in Cancers, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe epidermal growth factor receptor (EGFR) is overactive in many tumors. This phase I trial evaluated the safety and preliminary efficacy of afatinib plus capecitabine in refractory pancreatic ductal adenocarcinoma (PDA), biliary tract cancers (BTC), and other solid tumors. PATIENTS AND
methodsThe phase Ia study had a 3 + 3 design with capecitabine 1000 mg/m
resultsA total of 41 patients were enrolled. No dose-limiting toxicities were observed, and the MTD was 40 mg afatinib plus capecitabine. Among 36 response-evaluable patients, one had a partial response (3%), and eight (22%) had stable disease. Median progression-free survival (PFS) was 1.9 months (95% CI 1.0, 2.0) for PDA and 1.9 months (95% CI 1.6, 3.4) for BTC. Median overall survival (OS) was 3.2 months (95% CI 2.0, 5.8) for PDA, and 4.6 months (95% CI 1.9, 6.1) for BTC. Median OS was 5.8 months (95% CI 2.0, 9.6) for
conclusionsAfatinib plus capecitabine is tolerable but does not have clinically meaningful efficacy in refractory PDA/BTC. Future studies should test novel anti-EGFR/HER2 therapies in
