Authorised Therapeutic confirmatory (Phase III) HER2-positive locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma.

A trial comparing the treatment of rilvegostomig with fluoropyrimidine and trastuzumab deruxtecan to the standard treatment in patients with HER2-positive gastric cancer.

EU CTIS ID: 2024-512583-57-00

What this study is testing

To evaluate the efficacy of rilvegostomig in combination with fluoropyrimidine and T-DXd compared to trastuzumab, chemotherapy, and pembrolizumab, as measured by Progression-free Survival (PFS) per Blinded Independent Central Review and Overall Survival (OS).

Who can take part

You may be able to join if

  • HER2 positive for gastric cancer on a tumor biopsy.
  • PD-L1 combined positive score (CPS) ≥ 1.
  • Provision of tumor tissue sample from recent biopsy adequate for HER2 and PD-L1 testing.
  • Previously untreated, unresectable, locally advanced or metastatic gastric or GEJ adenocarcinoma.
  • WHO or Eastern Cooperative Oncology Group performance status of 0 or 1.
  • Have measurable target disease assessed by the Investigator based on RECISTv1.1.

You likely can't join if

  • Lack of physiological integrity of the upper gastrointestinal tract.
  • Any concurrent anti-cancer treatment with the exception of receptor activator ofnuclear factor kappa-B ligand inhibitors.
  • Have had major surgical procedure recently (excluding placement of vascular access) or recent significant traumatic injury or an anticipated need for major surgery during the study.
  • Known dihydropyrimidine dehydrogenase enzyme deficiency.
  • Current or prior use of immunosuppressive medication within 14 days before study intervention.
  • Contraindication to pembrolizumab or trastuzumab, contraindications tofluoropyrimidine (5-FU and capecitabine) or platinum (cisplatin and oxaliplatin) treatment as per local label.
