Trastuzumab deruxtecan in patients from China with previously treated human epidermal growth factor receptor 2-positive locally advanced/metastatic gastric or gastroesophageal junction adenocarcinoma (DESTINY-Gastric06): results from a single-arm, multicenter, phase 2 trial.
Article in EClinicalMedicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04989816 (A Single-arm Study of Trastuzumab Deruxtecan), which is not on this map. Cited by 12 papers, 2 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.
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.

Abstract
Background: Trastuzumab deruxtecan (T-DXd; 6·4 mg/kg) is approved for metastatic human epidermal growth factor receptor 2 (HER2)-positive (HER2+) gastric or gastroesophageal junction (GEJ) adenocarcinoma after a trastuzumab-based regimen. We report the final analysis of DESTINY-Gastric06, evaluating T-DXd in pretreated patients from China with advanced HER2+ gastric cancers (GC). Methods: The single-arm, multicenter, phase 2 DESTINY-Gastric06 trial (NCT04989816) enrolled patients from China with HER2+ (immunohistochemistry [IHC] 3+ or IHC 2+; locally documented) advanced gastric or GEJ adenocarcinoma with two or more prior treatments. Patients received T-DXd 6·4 mg/kg intravenous infusion every 3 weeks. The primary endpoint was confirmed objective response rate in HER2+ (IHC 3+ or IHC 2+/in situ hybridization-positive) tumors (full analysis set) by independent central review. Secondary endpoints included investigator-assessed confirmed objective response rate, progression-free survival by independent central review, overall survival, and safety. Findings: Of 126 patients screened between August 20, 2021, and December 7, 2022, 95 were enrolled (intent-to-treat; 73 patients had centrally confirmed HER2+ tumors). Median follow up was 10·2 months. Among the 73 patients, confirmed objective response rate (95% confidence interval) by independent central review was 28·8% (18·8-40·6%) and by investigator assessment was 37·0% (26·0-49·1%). Median progression-free survival by independent central review was 5·7 months. Median overall survival was 11·1 months. The most common Grade 1-2 adverse event was white blood cell count decreased (53·7%; 51/95). Interpretation: Consistent with other GC trials, T-DXd showed durable benefit, with no new safety signals, in pretreated patients from China with HER2+ advanced GC; data support T-DXd as a third- or later-line therapeutic option in this population.
