New treatment option for Adenocarcinoma
Official title Radiotherapy + Chemoimmunotherapy Followed by Surgery in Patients With Limited Metastatic Gastric or GEJ Cancer
ClinicalTrials.gov ID: NCT06121700
What this study is testing
What is Anti-PD-1 monoclonal antibody?
Anti-PD-1 monoclonal antibody is an investigational medicine, given as an once-daily infusion into a vein, being studied as a potential treatment for adenocarcinoma.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The goal of this clinical trial is to evaluate the efficacy and safety of radiotherapy combined with chemotherapy and anti-PD-1 immunotherapy followed by surgery for the primary and metastatic lesions in patients with limited metastatic gastric or gastroesophageal junction adenocarcinoma. The main questions it aims to answer are: 1) If the multimodal treatment which includes anti-PD-1 immunotherapy and local therapies will improve the survival of this group of patients.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
