PRODIGE 111 – DOMZIGAST A randomized phase II study evaluating FOLFIRI vs FOLFIRI plus Domvanalimab (anti-TIGIT) and Zimberelimab (anti-PD1) in patients with advanced gastric or gastro-oesophageal junction adenocarcinoma with progression during or after peri-operative chemotherapy.
EU CTIS ID: 2024-519258-35-00
What this study is testing
The main objective is to evaluate the progression-free survival (PFS) with FOLFIRI plus Zimberelimab and Domvanalimab versus FOLFIRI in patients with advanced-stage gastric or gastro-oesophageal junction or oesophageal adenocarcinoma who progressed/recurred (based on RECIST 1.1 evaluated by the investigator) during or with 6 months of platinum-based peri-operative treatment.

You may be able to join if
- Age ≥ 18 years

- Available tumor sample (before or after peri-operative treatment, archival or new tumor sample)
- Participation to all ancillary studies is mandatory
- Progression during or within 6 months after pre-operative, peri-operative or post-operative platinum-based therapy (i.e., FLOT, 5FU cisplatin or FOLFOX regimen) alone or combined with radiation
You likely can't join if
- Concurrent enrolment in another clinical study – unless it is an observational study or during the follow-up period of an interventional study
- History of idiopathic pulmonary fibrosis, interstitial lung disease, including history of interstitial lung disease or non-infectious pneumonitis, drug-induced pneumonitis, organizing pneumonia or evidence of active pneumonitis on screening chest CT-scan)

- Prior treatment by immune checkpoint inhibitor
- Known immunodeficiency or HIV infection with HIV viral load ≥200 copies/mL or CD4+ T-cell count <350 cells/μL or taking medications that may interfere with metabolism of study drugs
- Current or prior use of immunosuppressive medication within 14 days before the first dose of study drugs (excepted: intranasal, inhaled, topical steroids or local steroid injection –at physiological dose that does not exceed 10 mg/day of prednisone or its equivalent – steroids as premedication for hypersensitivity reactions)
