Of the 1070 patients in the safety analysis set, 77.4% were male, the median age was 70 years (range 23-100 years), and BMI was 20.4 kg/m2. ECOG PS was 0-1 and 2-4 in 89.9% and 10.1% of patients, respectively. The site of the primary lesion was the stomach in 81.6% of patients. The most common site of metastasis or recurrence was the lymph node in 66.5% of patients, followed by the liver (47.9%) and peritoneum (32.6%). The time from gastric cancer diagnosis to the initiation of T-DXd was >=12-<48 months in 67.6% of patients. A total of 78.4% of patients had SpO2 level >=95%, and 40.1% had creatinine clearance of >=60-<90 ml/min. ILD was reported as a medical history in 1.6% (n = 17) of patients and as a comorbidity in 0.4% (n = 4) of patients.
A total of 1129 patients were enrolled and their data were entered into CRFs. Of the 1129 patients, 1070 were included in the safety analysis set after excluding 59 patients [safety could not be evaluated by the investigator as there were no follow-up visits to the hospital after the first visit (n = 3), prior treatment with T-DXd (n = 49), or the site did not agree to provide data for publication (n = 7)].
In the safety analysis set (N = 1070), the incidence of any Grade, Grade >=3, and Grade 5 adjudicated drug-related ILD was 9.6%, 2.8%, and 1.2%, respectively. The median time from first T-DXd treatment to the first onset of adjudicated drug-related ILD episode was 2.9 months (range 0.3-11.5 months). The most common imaging pattern at the onset of adjudicated drug-related ILD was organizing pneumonia (62.1%), followed by hypersensitivity pneumonitis (20.4%) and diffuse alveolar damage (7.8%). Age (>=75 years), medical history and/or comorbidity of ILD, radiation pneumonitis, and chronic obstructive pulmonary disease (COPD) or emphysema were identified as factors of interest for ILD incidence.

All patients who initiated T-DXd treatment for human epidermal growth factor receptor 2 (HER2)-positive unresectable advanced or recurrent gastric cancer between September 2020 and December 2021 were enrolled and observed until T-DXd therapy termination or completion of 12 months of treatment.
The incidence of ILD with T-DXd in the real-world setting was similar to that observed in clinical trials, indicating no new ILD-related safety signals.
