Aim: This subgroup analysis of the RAINBOW study evaluated the efficacy and safety of ramucirumab in patients with gastric cancer/gastroesophageal junction adenocarcinoma who received prior trastuzumab therapy. Patients 95% CI: 7.0–17.9) versus placebo plus paclitaxel (7.0 months; 95% CI: 3.4–14.6), hazard ratio: 0.68 (0.33–1.41); p = 0.30. Longer progression-free survival, higher objective response were observed in ramucirumab combination group. Conclusion: Ramucirumab plus paclitaxel demonstrated efficacy benefits with manageable safety profile in a subgroup of patients pretreated with trastuzumab. Clinical trial registration number: NCT01170663.
