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 70 participants in total. It began in 2024-11-15 with a primary completion date of 2026-11-15.

Brief Summary

This study is a randomized, open label, parallel controlled trial aimed at evaluating and observing the efficacy and safety of the combination of donafenib and capecitabine as adjuvant therapy for postoperative treatment of biliary malignancies with high risk of recurrence. The study selected patients with biliary malignant tumors who are at high risk of postoperative recurrence as the research subjects. After the subjects sign the informed consent and pass the screening, they will be randomly divided into 1:1 groups. The experimental group consisted of Donafenib (200mg, bid) combined with capecitabine (1250mg/m2, bid, treated for 2 weeks and stopped for 1 week). The control group was capecitabine (1250mg/m2, bid, treated for 2 weeks and stopped for 1 week). Stop treatment until the subject experiences disease recurrence or intolerable toxic side effects. The primary endpoint of the study was the 1y RFS rate. Plan to include 70 participants.
