A First-in-Human Phase I Study of GC1118, a Novel Anti-Epidermal Growth Factor Receptor Antibody, in Patients with Advanced Solid Tumors.

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
lessons learnedGC1118 is a novel fully human anti-epidermal growth factor receptor (EGFR) antibody with unique binding epitopes and different ligand-binding inhibitory activity compared with cetuximab or panitumumab.GC1118 showed promising antitumor activity, especially in patients with colorectal cancer resistant to prior EGFR antibody. Skin toxicities were more common and diarrhea was less frequent compared with other anti-EGFR antibodies.
backgroundGC1118 is a novel monoclonal antibody targeting epidermal growth factor receptor (EGFR) with more potent ligand inhibition than cetuximab or panitumumab. We conducted a first-in-human, phase I study of GC118 in patients with refractory solid tumors.
methodsIn the dose escalation part, GC1118 was administered on days 1, 8, 15, and 22, followed by a 2-week rest, during which dose-limiting toxicities (DLTs) were evaluated. In the expansion part, patients were enrolled into three cohorts (Cohort 1 [C1], patients with colorectal cancer [CRC] without prior anti-EGFR treatment; Cohort 2 [C2], patients with CRC with tumors resistant to anti-EGFR therapy; Cohort 3 [C3], EGFR-overexpressing gastric cancer).
resultsIn the dose escalation part, 24 patients were treated at five dose levels: 0.3, 1.0, 3.0, 4.0, and 5.0 mg/kg. In the 5.0 mg/kg cohort, two patients experienced DLTs (skin toxicities). The maximum-tolerated dose (MTD) was 4.0 mg/kg. Common adverse events were skin toxicities. In the expansion part, 39 patients were enrolled. In Cohort 1, stable disease (SD) was observed in 58%; in Cohort 2, partial response (PR) 17% and SD 8%; in Cohort 3, PR 8% and SD 17%.
conclusionGC1118 showed promising antitumor activity and was well tolerated. Infrequent diarrhea compared with other anti-EGFR antibodies might be advantageous for further development.
