AACR Adaptive Biomarker-Driven Organ Preservation Trial in Gastroesophageal Adenocarcinomas (NCT07290985)

🩺 Plain-English Summary (8th-Grade Level)

This study will test a new personalized treatment approach for patients with stomach or esophageal cancer. It will take place in two stages and aims to find the best combination of chemotherapy, immunotherapy, and targeted drugs based on each patient's tumor biomarkers. Upon enrollment onto the study, patients will consent to tumor biomarker testing and may receive one cycle of standard chemotherapy while awaiting results. Those with a matching biomarker will join the corresponding treatment group that combines chemotherapy, an immune checkpoint inhibitor, and/or a targeted therapy. In Stage I of the study, treatment lasts about four months before surgery, followed by an additional eight months of therapy for a total of one year. The most effective treatments from Stage I will be studied further in Stage II of the study to see whether some patients can safely avoid surgery. Those patients enrolled during Stage II will receive four months of the same combination treatment (chemotherapy, an immune checkpoint inhibitor, and/or a targeted therapy) but may be eligible to skip surgery if their cancer completely disappears after pre-surgery therapy. All patients will then receive an additional eight months of therapy and those who skipped surgery will be closely monitored with scans and endoscopies.
