Abstract

Purpose Few data described the activity of chemotherapy after ramucirumab plus paclitaxel progression in metastatic gastric cancer patients. The aim of this phase II study is to assess the efficacy and safety of the FOLFIRI regimen as a third-line of treatment. Methods The study enrolled patients with histologically proven metastatic gastric cancer or gastroesophageal junction carcinoma whose disease had progressed after ramucirumab-based second line of treatment. Treatment consisted of biweekly irinotecan 150 mg/m2 as a 1-h infusion on day 1, folinic acid 100 mg/m2 intravenously on days 1–2, and 5-fluorouracil as a 400 mg/m2 bolus and then 600 mg/m2 continuous infusion over 22 h on days 1–2. Primary end-point was tumor response rate (confirmed complete and partial response). Results Twenty-six patients were enrolled. Overall response rate and disease control rate were 11.5% and 38.5%. The median progression free survival (PFS) was 52 days (95% CI:42–74), and the median overall survival was 117 days (95% CI: 94–154). no unexpected adverse events have been observed. A longer PFS and OS were observed in patients who had achieved PFS ≥ 3 months during prior ramucirumab treatment. Conclusions Our findings suggest a poor efficacy of the FOLFIRI regimen in metastatic gastric or gastroesophageal junction cancer patients whose disease progressed during a ramucirumab-based second line of treatment. However, FOLFIRI could be an option for patients who responded to prior ramucirumab.
