Brief Summary:

Following the results of study IMbrave150, the combination Atezolizumab + Bevacizumab is a promising treatment option for patients with HCC.

In addition, the high intrahepatic distant recurrence rate and accumulating evidence for a metastatic mechanism encourages exploring adjuvant/neoadjuvant strategies targeting tumor growth and metastatic escape in the context of percutaneous thermal ablation for small HCC.

Local ablation of HCC is therefore an "ideal" setting for testing atezolizumab + bevacizumab in combination with ablation, with the aim of reducing the risk of recurrence.


Condition or disease Intervention/treatment Phase
Hepatocellular Carcinoma Drug: Atezolizumab (neoadjuvant) Procedure: Percutaneous Radiofrequency Drug: Bevacizumab (adjuvant) Drug: Atezolizumab (adjuvant) Phase 2

Detailed Description:

Liver cancer is the sixth most common cancer and the third leading cause of death from cancer worldwide (source: Globocan 2018). Hepatocellular carcinoma (HCC) represents 80-90% of liver cancers. Percutaneous thermal ablation (PTA) is a validated treatment option for very early and early stage HCC, together with surgical resection and liver transplantation (EASL Clinical Practice Guidelines: Management of hepatocellular carcinoma, J Hepatol 2018). Due to its excellent tolerance, particularly in patients with portal hypertension or bearing comorbidities, it now represents in France nearly 70% of the first-line curative treatment of "in Milan" tumours. The risk of local tumor progression (LTP) is ≈10-20% in PTA series (Nault, J Hepatol 2018; N'Kontchou et al., Hepatology (Baltimore, Md) 2009). In addition, the long-term results of PTA are influenced by the high rate (up to 60-80% at 5 years) of intrahepatic distant recurrence (IDR) (Nault et al., J Hepatol 2018), as observed also after HCC surgical resection (EASL Clinical Practice Guidelines: Management of hepatocellular carcinoma, J Hepatol 2018; Imamura et al., J Hepatol 2003). It is unknown whether early IDR (2-3 years after PTA of <3 cm HCC) is due to metastatic spread or de novo carcinogenesis.

Strong scientific rationale and emerging clinical data suggest that the combined vascular endothelial growth factor (VEGF) / Programmed death-ligand 1 (PD-L1) blockade may be clinically beneficial in a number of tumor types, including HCC. Therefore, local ablation in HCC is an " ideal " context to test Atezolizumab + Bevacizumab in combination with ablation. The investigators hypothesized that the combo of Atezolizumab + Bevacizumab and radiofrequency ablation could improve recurrence-free survival (RFS) at 2 years.

The aim of this randomized multicentre phase II trial is to compare RFS at 2 years in the experimental arm (Atezolizumab + Bevacizumab + RF ablation) versus the control arm (RF ablation) according to HCC modified response evaluation criteria in solid tumours (mRECIST). Thus the proposed use here of Atezolizumab as first neoadjuvant, then in combination with Bevacizumab as adjuvants, should theoretically, and hopefully, limit the radiofrequency ablation (RFA) pro-tumor effects. The RFS current rate value of 45% corresponding to the standard procedure of RFA alone (i.e. in the Active Comparator arm) should be increasing to at least 65% because of the addition of the biotherapy (i.e. in the Experimental arm). The patients' recruitment timeframe is set at 36 months and the patient's follow-up timeframe is 5 years. 202 patients are to be included, 101 per arm.
