Descriptive Information

• Brief Title: Atezolizumab/Bevacizumab Followed by On-demand TACE or Initial Synchronous Treatment With TACE and Atezolizumab/Bevacizumab
• Official Title: A Randomized, 2-arm Non-comparative Phase II Study on the Efficacy of Atezolizumab and Roche Bevacizumab (Atezo/Bev) Followed by On-demand Selective TACE (sdTACE) Upon Detection of Disease Progression or of Initial Synchronous Treatment With TACE and Atezo/Bev on 24-months Survival Rate in the Treatment of Unresectable Hepatocellular Carcinoma Patients
• Brief Summary: Aim of the study is to evaluate the efficacy of up-front atezolizumab/ bevacizumab (Atezo/Bev) followed by on-demand selective transarterial chemoembolization (sdTACE) and of initial synchronous treatment with TACE and Atezo/Bev in the treatment of unresectable HCC patients.
• Detailed Description: Not Provided
• Study Type: Interventional
• Study Phase: Phase 2
• Study Design: Allocation: Randomized; Intervention Model: Parallel Assignment; Masking: None (Open Label); Primary Purpose: Treatment
• Condition: Hepatocellular Carcinoma Non-resectable

Intervention

Combination Product: Atezolizumab Injection, Bevacizumab Injection

Atezolizumab and Bevacizumab will be administered prior to or in combination with TACE

Other Name: Chemoembolisation (TACE)

Study Arms

• Experimental: Up-front Atezo/Bev, then TACE
  Patients will receive atezolizumab and bevacizumab iv every three weeks for up to 24 months. Upon detection of at least one unequivocal progressive hepatic lesion, selective TACE directed against progressive lesion(s) (sdTACE) will be performed. RFA or MWA are permitted as alternative to TACE to treat one or more lesion that cannot be reasonably selectively targeted by TACE
  Intervention: Combination Product: Atezolizumab Injection, Bevacizumab Injection
• Experimental: Atezo/Bev combined with TACE
  First TACE will be performed as selectively as possible against all viable tumor lesions. Atezo/Bev will be initiated within three days from TACE. Upon detection of at least one unequivocal progressive hepatic lesion, treatment with Atezo/Bev will be continued if RFA or MWA can be used to treat this/these progressive lesion.
  Intervention: Combination Product: Atezolizumab Injection, Bevacizumab Injection
