PURPOSE: Continuous use of antiangiogenic agents has demonstrated survival benefits in various cancers. This trial aimed to compare the efficacy and safety of ramucirumab plus irinotecan with irinotecan monotherapy as a third- or later-line treatment for patients with advanced or recurrent gastric or gastroesophageal cancer (AGC) that has progressed on previous ramucirumab-based chemotherapy.
METHODS: Patients age 20 years and older with AGC, who had experienced disease progression during ramucirumab-based chemotherapy, were randomly assigned to receive either ramucirumab plus irinotecan or irinotecan monotherapy. The primary end point was overall survival (OS) expecting a hazard ratio (HR) of 0.77 (a power of 80% and a significance level of one-sided 0.05). Secondary end points included progression-free survival (PFS), response rate, disease control rate (DCR), and safety.
RESULTS: Between February 2017 and August 2022, 402 patients in Japan were randomly assigned to receive ramucirumab plus irinotecan (n = 202) or irinotecan monotherapy (n = 200). The median OS was 9.4 months in the combination arm and 8.5 months in the monotherapy arm, with an adjusted HR of 0.91 (95% CI, 0.74 to 1.12; P = .49). PFS was improved (median, 3.8 v 2.8 months; HR, 0.72 [95% CI, 0.59 to 0.89]; P = .002), while the DCR was significantly better (64.4% v 52.1%; P = .03) with the combination therapy. The adverse events of the combination therapy were manageable.
CONCLUSION: Adding ramucirumab to irinotecan does not provide a significant advantage in OS over irinotecan alone in patients with AGC who have progressed during ramucirumab-containing chemotherapy.
