The FDA approved fam-trastuzumab deruxtecan-nxki (Enhertu®, Daiichi Sankyo) for the treatment of adult patients with locally advanced or metastatic human epidermal growth factor receptor 2 (HER2)-positive gastric or gastroesophageal adenocarcinoma previously treated with a trastuzumab-based regimen. Approval was based on DESTINY-Gastric01 (NCT03329690), a multicenter, open-label, randomized trial. For this study, led by study author Kohei Shitara, MD, Chief of the Department of Gastrointestinal ...

In patients with locally advanced gastric cancer, perioperative chemotherapy consisting of TAS-118 (S-1 and leucovorin) plus oxaliplatin shows promise with a tolerable safety profile, according to safety and efficacy results of the APOLLO-11 feasibility study to be presented this week at the 2021 Gastrointestinal Cancers Symposium. While preoperative TAS-118 plus oxaliplatin followed by D2 gastrectomy has been shown to be feasible for patients with gastric cancer, the efficacy of this regimen in...

In advanced gastric cancer and gastroesophageal junction cancer, treatment options remain limited. Results of the phase 3 CheckMate 649 and phase 2/3 ATTRACTION-4 studies, both of which investigated chemotherapy with or without nivolumab in patients with previously untreated unresectable, advanced, or recurrent gastric/gastroesophageal junction (G/GEJ) cancer, were recently presented at the European Society of Medical Oncology (ESMO) Virtual Congress 2020. CheckMate 649 reported significant impr...

Gastric or gastroesophageal junction (G/GEJ) cancer constitutes the third leading cause of cancer death worldwide, and more therapeutic options are needed. In results from the phase 3 KEYNOTE-062 study, published last week in JAMA Oncology, Kohei Shitara, MD, and colleagues reported that in patients with previously untreated G/GEJ cancer with a programmed cell death ligand 1 (PD-L1) combined positive score (CPS) of 1 or greater, pembrolizumab, alone or in combination with chemotherapy, was nonin...

Data from the phase 3 KEYNOTE-062 trial have revealed that in patients with advanced gastric or gastroesophageal junction (G/GEJ) cancer with a programmed cell death ligand 1 (PD-L1) combined positive score (CPS) of 1 or greater, first-line pembrolizumab, alone or in combination with chemotherapy, is noninferior but not superior to chemotherapy alone. In patients with a PD-L1 CPS of 10 or greater, pembrolizumab monotherapy showed a possible benefit, but one that cannot be considered definitive o...
