This is a pilot study with a single arm in a single center assessing safety and efficacy of
combination therapy of TACE and ablation and durvalumab. This study will be conducted in
selected patients with intermediate stage HCC not amenable to curative therapy.
Approximately 30 patients will be enrolled and receive the following treatments:
TACE (day 1, up to twice. TACE interval will be 4～6 weeks) → Ablation (4 weeks after the last
TACE, up to twice. Ablation interval will be 4～6 weeks) → Durvalumab (at least 1 week after
the last ablation, 1500 mg Q4W, until mRECIST criteria defined radiological progression or
other discontinuation criteria were met, but no more than 1 year).

requirements and restrictions listed in the informed consent form (ICF) and in this
protocol. Written informed consent and any locally required authorization (eg, Health

Privacy Directive in the EU) obtained from the patient/legal representative prior to
performing any protocol-related procedures, including screening evaluations.

confirmation diagnosis is provided by the study site. Definition of radiological
confirmation: Clinical findings consistent with the diagnosis of a liver mass

in the hepatic arterial-dominant phase and contrast washout in the late portal venous
phase) seen in either triphasic computed tomography (CT) scan or magnetic resonance
- HCC newly diagnosed or recurrent with a history of surgery or ablation, with Barcelona
Clinic Liver Cancer (BCLC) Stage B not amenable to curative surgery or transplantation
or that the patient refuses surgery.

experienced doctor to assess and perform ablation procedure).

(ANC) ≥1.0 × 10^9 /L; c. Platelet count ≥50 × 10^9/L; d. Serum total bilirubin ≤2 ×
institutional upper limit of normal (ULN); e. AST (SGOT)/ALT (SGPT) ≤5× ULN; f.
Albumin ≥28 g/L; g. International normalized ratio ≤1.6 and prothrombin time ≤16 s; h.
Measured creatinine clearance (CL) >50 mL/min or Calculated creatinine CL>50 mL/min by
the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection
for determination of creatinine clearance: Males: Creatinine CL (mL/min)=Weight (kg) x
(140-Age) / (72 x serum creatinine), Females: Creatinine CL (mL/min)=Weight (kg) x
(140-Age) ×0.85 / (72 x serum creatinine).

therapy), including investigational products. Concurrent enrolment in another clinical
study, unless it is an observational (non-interventional) clinical study or during the

radical surgery or ablation are allowed. Evidence for radical surgery or ablation
should be provided with enhanced MRI/CT after at least 4 weeks after the treatment and
