The study demonstrated that the combination therapy of trifluridine/tipiracil and ramucirumab showed an acceptable safety profile and clinical activity in patients with previously treated advanced gastric cancer.
Background Findings of preclinical and clinical trials in colorectal cancer have shown promising antitumour effects of the co-formulation trifluridine/tipiracil and VEGF inhibition. We aimed to investigate the safety and activity of trifluridine/tipiracil and ramucirumab for previously treated advanced gastric cancer. Methods We did an open-label, single-arm, two-cohort, phase 2 study at eight centres in Japan. We enrolled patients with unresectable advanced gastric cancer or gastro-oesophageal junction adenocarcinoma. Cohort A included patients previously treated with one line of chemotherapy without ramucirumab and cohort B included patients previously treated with two to four lines of chemotherapy, including ramucirumab. Patients received trifluridine/tipiracil (35 mg/m(2)) orally twice daily on days 1-5 and days 8-12 of each 28-day treatment cycle, plus intravenous ramucirumab (8 mg/kg) on days 1 and 15. The primary endpoint was the disease control rate, assessed by investigators and defined as the proportion of patients with a confirmed best overall response, according to Response Evaluation Criteria in Solid Tumors version 1.1. This trial is registered on JapicCTI (JapicCTI-194596) and is ongoing but not recruiting. Findings Between April 8 and Oct 11, 2019, 64 patients were enrolled and included in the safety and activity analyses, 33 in cohort A and 31 in cohort B. In cohort A, the disease control rate was 85% (95% CI 68-95; 28 of 33 patients) and in cohort B it was 77% (59-90; 24 of 31 patients). Common treatment-related adverse events of grade 3 or worse were neutrophil count decreased (27 [82%] in cohort A and 23 [74%] in cohort B), white blood cell count decreased (eight [24%] and seven [23%]), and platelet count decreased (eight [24%] and four [13%]). Serious treatment-related adverse events were recorded in three patients in cohort A (fatigue and neutrophil count decreased; large intestine perforation; and febrile neutropenia, platelet count decreased, and anaemia). No patients in cohort B had a serious treatment-related adverse event, and no treatment-related deaths were reported in either cohort. Interpretation Trifluridine/tipiracil and ramucirumab showed an acceptable safety profile and clinical activity in patients with previously treated advanced gastric cancer regardless of previous ramucirumab exposure.
