What the trial is, and whether it could suit you
This study is a prospective, multicenter, single-arm, open-label Phase II clinical trial, planned to enroll 30 patients with unresectable locally advanced or metastatic iCCA/GBC. Patients will first receive cryoablation treatment, and two weeks after ablation, they will receive 8 cycles of immunotherapy combined with chemotherapy (Relatlimab α plus GC chemotherapy, every 3 weeks). During the maintenance phase, patients will continue with Relatlimab α alone, every 3 weeks, for up to one year. During the combination treatment phase, efficacy will be evaluated every 6 weeks, and during the maintenance phase, every 6 to 9 weeks. From the date of randomization/enrollment, survival follow-ups will be conducted every 3 months (±14 days) for the first 2 years; afterwards, follow-ups will occur every 6 months (±28 days) until the participant dies, is lost to follow-up, or the study ends, whicheve
