About this trial

This early phase (Phase 1) study will evaluate BRII 5395, administered in combination with two approved anticancer agents, sintilimab and bevacizumab, in patients with advanced liver cancer caused by chronic hepatitis B virus (HBV) infection. The primary objective of the study is to assess the safety and tolerability of the combination therapy, as well as to explore preliminary evidence of clinical benefit.
