DEMAND: Atezolizumab/Bevacizumab Followed by On-demand TACE or Initial Synchronous Treatment With TACE and Atezolizumab/Bevacizumab
Study Details
Study Description
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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| 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 |
Combination Product: Atezolizumab Injection, Bevacizumab Injection
Atezolizumab and Bevacizumab will be administered prior to or in combination with TACE

| 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. |
