What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 37 participants in total. It began in 2023-06-01 with a primary completion date of 2025-12-31.

Brief Summary

The aim of this study was to evaluate the efficacy and safety of Camrelizumab combined with gemcitabine and oxaliplatin (GEMOX) for unresectable gallbladder cancer. Patients with unresectable gallbladder cancer were enrolled to receive gemcitabine 1000mg/m2 D1+oxaliplatin 100mg/m2, D1+Camrelizumab 200mg, D1, in 21-day cycles for 6-8 cycles, with serum tumour markers assessed at each course and abdominal CTA performed every two courses, until tumour progression occurs.The primary indicators of this study are radical tumor resection rate; secondary indicators are disease control rate, objective response rate,progression-free survival and overall survival; safety indicators: incidence and severity of adverse events (AEs) and serious adverse events (SAEs) according to NCI-CTCAEv5.0 criteria. 37 patients are expected to be recruited for this study.
