LBA58 A randomized phase III trial of perioperative chemotherapy (periop CT) with or without preoperative chemoradiotherapy (preop CRT) for resectable gastric cancer (AGITG TOPGEAR): final results from an intergroup trial of AGITG, TROG, EORTC and CCTG. T Leong

  • TOPGEAR is an important academic trial which looks at the benefit of adding radiotherapy to neoadjuvant chemotherapy in operable gastric and gastroesophageal cancer. There is a major unmet need to improve outcomes for this patient group, as currently only 50% of patients are cured of their cancer following chemotherapy and surgery.

1401O Trastuzumab deruxtecan (T-DXd) monotherapy and combinations in patients (pts) with advanced/metastatic HER2-positive (HER2+) esophageal, gastric or gastroesophageal junction adenocarcinoma (GEJA): DESTINY-Gastric03 (DG-03). YY Janjigian

  • For patients with HER2-positive GEA, historically, trastuzumab in combination with chemotherapy was the standard of care, but outcomes were very modest compared with those among patients with HER2-positive breast cancer. The KEYNOTE-811 trial demonstrated the efficacy of combining chemotherapy and trastuzumab with pembrolizumab, but importantly only for patients who were double-biomarker positive. This key finding, regarding the importance of immune context, was highlighted again in updated results presented at ESMO. KEYNOTE-811 is a negative trial overall, but the combination of triple therapy improved overall survival for HER2- and PD-L1–positive patients (who represented the majority of the population, 85%) sufficiently for this to become a standard of care. Importantly, a detriment in overall survival was seen when pembrolizumab was added to chemotherapy and trastuzumab for HER2-positive PD-L1–negative patients, and immune checkpoint inhibitors are not recommended for this group of patients.
  • Trastuzumab deruxtecan (T-DXd), an antibody–drug conjugate targeting HER2, is established as standard of care in HER2-positive GEA after progression on trastuzumab. In the DESTINY-Gastric03 trial, the first results of T-DXd in first-line HER2-positive GEA are shown. T-DXd as monotherapy showed comparable results in the first line compared with second-line therapy. The addition of 5-FU also increased response rates in all patients. However, adding pembrolizumab to T-DXd improved results only for PD-L1–positive patients, and it may have had a detriment in ORR in PD-L1–negative patients. These results underscore the results of KEYNOTE-811, in that HER2-positive GEA is comprised of two distinct biological entities, which should be treated differently according to PD-L1 status. Finally, interstitial lung disease (ILD), which is a previously identified concern for many antibody–drug conjugates, was identified in 11% of patients, with some deaths occurring. Early detection and timely management of ILD will be important in any ensuing registration trials in the first-line setting.
