Clinical Trial Summary

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.

Description:

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).

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).

• Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.

Exclusion Criteria:

• History or concurrent use of anticancer therapy (local regional therapy and systemic therapy), including investigational products. Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study. Patients with the recurrence from a 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 AFP level should also be negative in at least 4 weeks after the radical treatment; Chinese traditional medicine with CFDA approval for anticancer use should be washout for 14 days before enrolment.

• Active infection including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice).
