About this study

This study is a Phase 2/3, prospective, multicenter, open-label, non-randomized clinical trial, in which GEH300079 (68Ga) PET/CT images will be acquired in patients with primary colorectal, gastric, ovarian, or Pancreatic Ductal Adenocarcinoma (PDAC) cancers and known or suspected Peritoneal Carcinomatosis (PC) before or after institutional Standard of Care (SoC) imaging. The primary objective is to evaluate the diagnostic performance of GEH300079 (68Ga) PET/CT for the detection of PC in patients with colorectal, gastric, or ovarian primary cancers, using a composite standard of truth (SoT), in a region-based analysis. The detection of PC in patients with primary PDAC will be explored in the Phase 2 part of the study. The study is comprised of 2 distinct parts: Phase 2 aims to confirm the statistical and scientific assumptions for the Phase 3 part, and to confirm the optimal dose and timing of acquisition of GEH300079 (68Ga) PET/CT in the PC indication. Phase 2 includes 2 cohorts: Cohort A (participants with colorectal, ovarian and gastric primary cancer), and Cohort B (participants with primary PDAC), where analysis of Cohort B is descriptive only. Phase 3 aims to demonstrate the safety and efficacy of GEH300079 (68Ga) PET/CT for the detection of PC in patients with confirmed colorectal, gastric or ovarian primary cancers.
