Sponsor

GERCOR - Multidisciplinary Oncology Cooperative Group

Enrollment

120 participants

Start Date

Apr 16, 2024

Study Type

INTERVENTIONAL

Conditions

Summary

This is a randomized non-comparative, multicenter phase II study in patients with PD-L1 PD-L1 combined positive score (CPS) ≥5 advanced gastric cancer to evaluate the efficacy and safety of nivolumab and FOLFOX in combination with EXL01 as first-line treatment. After signing the informed consent form, and upon confirmation of the patient's eligibility, patients will be randomized in a 2:1 ratio to either the nivolumab and FOLFOX plus EXL01 arm (experimental) or the nivolumab and FOLFOX arm (control). In both arms, treatment will be given until PD, unacceptable toxicity or for a maximum of 24 months (52 cycles).


Eligibility

Min Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This trial tests EXL01 (a new immunotherapy drug) combined with nivolumab and a standard chemotherapy regimen (FOLFOX) as a first-line treatment for advanced stomach or lower esophageal cancer. Only patients whose tumors express a protein called PD-L1 at moderate-to-high levels (CPS ≥5) are included. The goal is to see if this triple combination works better than current standard care. **You may be eligible if...** - You are 18 or older with confirmed advanced or metastatic stomach or gastroesophageal junction adenocarcinoma - Your tumor has a PD-L1 CPS score of 5 or higher - You have not received prior treatment for your metastatic disease - You have measurable disease on imaging - You are in good physical health **You may NOT be eligible if...** - You have received prior chemotherapy or immunotherapy for this cancer - You have active autoimmune disease or conditions requiring immune-suppressing medications - You have brain metastases or other serious co-existing illnesses Talk to your doctor to see if this trial is right for you.
