First-line pembrolizumab plus chemotherapy for advanced/metastatic esophageal cancer: 1-year extended follow-up in the Japanese subgroup of the phase 3 KEYNOTE-590 study
Background
First-line pembrolizumab plus chemotherapy (pembrolizumab–chemotherapy) demonstrated improved efficacy and a manageable safety profile versus placebo plus chemotherapy (placebo–chemotherapy) in the subgroup analysis of Japanese patients with advanced/metastatic esophageal cancer in KEYNOTE-590 at a median follow-up of 24.4 months. Longer-term data from the Japanese subgroup analysis of KEYNOTE-590 are reported.
Methods
Patients were randomly assigned 1:1 to pembrolizumab 200 mg or placebo every 3 weeks for ≤ 35 cycles plus chemotherapy (cisplatin 80 mg/m2 and 5-fluorouracil 800 mg/m2/day). Endpoints included overall survival (OS) and progression-free survival (PFS; investigator-assessed per RECIST v1.1; dual primary) and safety (secondary). Early tumor shrinkage (ETS) and depth of response (DpR) were assessed post hoc.
Results
Overall, 141 patients were enrolled in Japan. As of July 9, 2021, median follow-up was 36.6 months (range, 29.8–45.7). Pembrolizumab–chemotherapy showed a trend toward favorable OS (hazard ratio [HR], 0.70; 95% confidence interval [CI] 0.47–1.03) and PFS (0.57; 0.39–0.83) versus placebo–chemotherapy. In the pembrolizumab–chemotherapy group, patients with ETS ≥ 20% (55/74; 74.3%) versus < 20% (19/74; 25.7%) had favorable OS (HR, 0.23; 95% CI 0.12–0.42) and PFS (0.24; 0.13–0.43). Patients with DpR ≥ 60% (31/74; 41.9%) versus < 60% (43/74; 58.1%) had favorable OS (HR, 0.37; 95% CI 0.20–0.68) and PFS (0.24; 0.13–0.43). Grade 3–5 treatment-related adverse events occurred in 55/74 patients (74.3%) with pembrolizumab–chemotherapy and 41/67 patients (61.2%) with placebo–chemotherapy.
Conclusions
With longer-term follow-up of Japanese patients with advanced/metastatic esophageal cancer, efficacy continued to favor pembrolizumab–chemotherapy compared with placebo–chemotherapy, with no new safety signals observed.
期刊介绍：
Esophagus, the official journal of the Japan Esophageal Society, introduces practitioners and researchers to significant studies in the fields of benign and malignant diseases of the esophagus. The journal welcomes original articles, review articles, and short articles including technical notes ( How I do it ), which will be peer-reviewed by the editorial board. Letters to the editor are also welcome. Special articles on esophageal diseases will be provided by the editorial board, and proceedings of symposia and workshops will be included in special issues for the Annual Congress of the Society.
