The IMbrave050 showed that the combination atezolizumab/bevacizumab improved recurrence free survival in high risk resected HCC patients with RFS 78% vs 65% at 12 months, HR 0.72 (95% CI 0.56, 0.93), this tapered off at approximately 24 months. This suggests that the combination delayed recurrence a...

UPDATE 2025. The last presentation at ESMO 2024 showed a slightly inferior PFS for the treatment arm, ...

Update 4/7/25: Updated results for IMbrave050 were presented at ESMO 2024 and indicated no significant improvement in OS. A small percent (7%) continued to derive an RFS benefit. This has to be considered with the AE profile- with 9% of patients discontinuing treatment due to a TRAE. The updates con...
