New hope for stomach cancer: targeted drug combo under study
NCT ID NCT07427992
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing a drug called zolbetuximab combined with standard chemotherapy in people with a specific type of advanced stomach cancer that has spread. The cancer must have a protein called claudin 18.2 on at least 75% of its cells and be HER2-negative. The goal is to see how well the treatment works in real-world settings, outside of a controlled clinical trial. About 70 participants will be enrolled.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Zolbetuximab (a targeted antibody) combined with chemotherapy (FOLFOX or XELOX)
- What this could lead to
- If it works, this could provide a new treatment option for people with a specific type of advanced stomach cancer that is hard to treat.
- What could go wrong
- This is an early real-world study, not a large randomized trial, so results may be less reliable. The treatment may not improve survival and could cause side effects from chemotherapy.

Inclusion Criteria: * Patient with histologically confirmed diagnosis of gastric or gastroesophageal junction adenocarcinoma. * Patient with locally advanced, unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma. * Patient whose tumor expresses claudin18.2 in ≥ 75% of tumor cells demonstrating moderate to strong membranous CLDN18 staining as determined by local or central immunohistochemistry testing. * Patient with a Human epidermal growth factor receptor 2 negative tumor by local testing on a gastric or gastroesophageal junction tumor specimen. * Patient with Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1. * Patient who can have access to the Zolbetuximab EAP program or locally authorized and reimbursed (AIFA) procedure. * Patient who has about to start first-line Zolbetuximab + FOLFOX/XELOX or who has an ongoing Zolbetuximab FOLFOX/XELOX with available clinical data. Exclusion Criteria: * Patient has previously received treatment in a clinical trial of zolbetuximab, or a clinical trial that included zolbetuximab as 1 of the treatment options, even if the patient was not given zolbetuximab. * Patient has known dihydropyrimidine dehydrogenase deficiency. * Patient has received prior systemic chemotherapy for locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma. However, patient may have received either neoadjuvant or adjuvant chemotherapy, immunotherapy or other systemic anticancer therapies as long as it was completed at least 6 months prior to participation.
