Phase 1/2RecruitingKyushu UniversityNCT05438459Data as of May 2026

Treatment: Phase I part · Phase II partPhase I Part : Confirm the safety of GAIA-102 as a monotherapy or GAIA-102 and pembrolizumab in combination for advanced gastrointestinal cancer of microsatellite stable with malignant ascites, and determine the recommended number of doses for Phase II part. Phase II Part : Research the efficacy and safety of as a monotherapy or GAIA-102 and pembrolizumab for advanced gastrointestinal cancer of microsatellite stable with malignant ascites at the recommended dose of GAIA-102 decided in the Phase I part.
