A Phase I study of pevonedistat plus capecitabine plus oxaliplatin in patients with advanced gastric cancer refractory to platinum (NCCH-1811)

Abstract

Based on synergistic anti-tumor effects between blockades of NEDD8 activating enzyme and a platinum in preclinical studies, this Phase I study is designed to investigate the safety and tolerability of pevonedistat in combination with capecitabine plus oxaliplatin as third-line or later treatment in patients with unresectable advanced/recurrent gastric cancer who were previously treated with fluoropyrimidines and platinum (cisplatin or oxaliplatin) as the first-line treatment and paclitaxel (including nab-paclitaxel) as the second-line treatment. The aim of this trial is to determine the recommended dose of pevonedistat and to see its pharmacokinetics in combination with capecitabine plus oxaliplatin in the dose-finding part and explore its efficacy and safety in the expansion part. Trial registration number: jRCT2031190020 (jRCTs: the Japan Registry of Clinical Trials).
