Is NCT06253650 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies Experimental for gastric cancer.

Phase 2RecruitingGruppo Oncologico del Nord-OvestNCT06253650Data as of May 2026

Treatment: ExperimentalTRINITY is designed as a multicentre, randomized, open-label, interventional phase II study aimed at investigating the activity, efficacy and safety of trastuzumab-deruxtecan (T-DXd) plus capecitabine/5-fluorouracil as a post-operative treatment in localized/locally advanced gastric or gastroesophageal junction cancer (GC/GEJC)/esophageal adenocarcinoma patients with HER2 overexpression/amplification and positive post-operative ctDNA after pre-operative 5-fluorouracil plus leucovorin, oxaliplatin, and docetaxel (FLOT) regimen followed by radical surgery.
