Phase1; Phase2 Interventional University Health Network, Toronto · NCT06725121

What this trial studies

This clinical trial evaluates the effectiveness of combining locoregional therapy, specifically stereotactic body radiotherapy (SBRT) or Yttrium-90 (Y-90), with immunotherapy using Atezolizumab and Bevacizumab in patients with advanced hepatocellular carcinoma (HCC) and macrovascular invasion. Participants will undergo a biopsy, receive the combined treatment, and may be referred for liver transplantation if eligible. The study aims to determine the number of patients who achieve successful transplantation and assess their 5-year survival and recurrence-free survival rates. It is a pilot, open-label, single-arm study focused on integrating these therapies into the liver transplantation pathway.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 with advanced hepatocellular carcinoma and macrovascular invasion who meet specific health criteria.

Not a fit: Patients with poorly differentiated HCC, extrahepatic disease, or contraindications to the therapies involved may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly increase the number of patients with advanced liver cancer who are eligible for liver transplantation.

How similar studies have performed: While this approach is innovative, similar studies combining locoregional therapy with immunotherapy have shown promise, indicating potential for success.
