Is this trial a fit for you?

Likely a good fit

Adults with locally advanced or metastatic HBV-related HCC (BCLC B or C) who have failed at least first-line systemic therapy and are not candidates for curative surgery or local therapies.

Probably not a fit

Patients with contraindications to any study drugs, poor organ function, or rapid disease progression may not benefit from this therapy.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 1 trial evaluating the safety and tolerability of BRII-5395 in combination with sintilimab and bevacizumab in patients with advanced hepatocellular carcinoma related to chronic hepatitis B. Eligible participants have locally advanced or metastatic disease not suitable for surgery, have failed prior therapies (including ICIs), and have adequate organ function. The study will monitor adverse events and collect preliminary signals of clinical activity to inform future research. Enrollment is focused at the Cancer Institute and Hospital, Chinese Academy of Medical Sciences in Beijing. No collaborators are listed for this trial.

Why it matters

Potential benefit: If successful, participants may experience disease stabilization or clinical benefit from the combination therapy during the trial.

How similar studies have gone: Early-phase studies of combination immunotherapy with anti-angiogenic agents are progressing in hepatocellular carcinoma, with some signals of safety and potential activity in other settings, but this exact combination is novel for HBV-related HCC.
