Study Details

Study Description

Brief Summary

This study is a prospective phase II, single arm mono-institutional study conducted in Queen Mary Hospital (Hong Kong) assessing the efficacy and safety of the sequential administration of trans-arterial chemo-embolization (TACE) and stereotactic body radiotherapy (SBRT) with an immune checkpoint inhibitor in hepatocellular carcinoma (HCC) patients.

Condition or Disease	Intervention/Treatment	Phase
HCC	Procedure: TACE Radiation: SBRT Drug: Immune Checkpoint Inhibitor	Phase 2

Detailed Description

All the patients must be registered with the Investigator(s) prior to initiation of treatment. The registration desk will confirm all eligibility criteria and obtain essential information (including patient number).

TACE should start within 28 days of study registration and its procedure will be standardised.

SBRT screening and planning will be performed by radiation therapists, medical physicists, and oncologists.

Outcome Measures

Primary Outcome Measures

Number of Patients Amendable to Curative Surgical Interventions [from the date of first study treatment to the date of last study treatment, an average of 3 years]
Number of patients amendable to curative surgical interventions defined as number of patients receiving curative surgical resection or transplantation after successful down-sizing of tumor(s) by intervention.

Secondary Outcome Measures

Response rate measured by mRECIST criteria [from the date of screening to radiographically documented progression according to mRECIST 1.1, assessed up to 3 years]
Complete response (CR): Disappearance of any intra-tumoral arterial enhancement in all target lesions Partial response (PR): At least a 30% decrease in the sum of diameters of viable (enhancement in the arterial phase) target lesions, taking as reference the baseline sum of the diameters of target lesions Stable disease (SD): Any cases that do not qualify for either partial response or progressive disease Progressive disease (PD): An increase of at least 20% in the sum of the diameters of viable (enhancing) target lesions, taking as reference the smallest sum of the diameters of viable (enhancing) target lesions recorded since treatment started
Time to progression (TTP) [from the date of first study treatment to radiographically documented progression according to mRECIST 1.1, assessed up to 3 years]
Time to progression (TTP): measured from the date of first study treatment to radiographically documented progression according to mRECIST 1.1. This does not include death from any cause.
Progression-free survival (PFS) [from the date of first study treatment to radiographically documented progression according to mRECIST 1.1 or death from any cause, whichever occurs first, assessed up to 3 years]
Progression-free survival (PFS): measured from the date of first study treatment to radiographically documented progression according to mRECIST 1.1 or death from any cause (whichever occurs first). Participants alive and without disease progression or lost to follow-up will be censored at the date of their last radiographic assessment.
Overall survival (OS) [from the date of first study treatment to the date of death from any cause, assessed up to 5 years]
Overall survival (OS): measured from date of first study treatment to the date of death from any cause. Participants alive or lost to follow-up will be censored at the date of their last visit.
European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC-QLQ-C30) Score [from the date of screening to radiographically documented progression according to mRECIST 1.1, an average of 3 years]
Quality-of-Life (QoL) is assessed by the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC-QLQ-C30).
Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) Score [from the date of screening to radiographically documented progression according to mRECIST 1.1, an average of 3 years]
Quality-of-Life (QoL) is also assessed by the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) questionnaires.
Incidence of Study-Related Adverse Events [Safety and Tolerability] [from the date of screening to 90 days after last treatment, around 3 years and 90 days]
Incidence, nature, and severity of adverse events graded according to the United States National Cancer Institute The Common Terminology Criteria for Adverse Events (NCI CTCAE 4.0)
Pathological response [from the date of first study treatment to radiographically documented progression according to mRECIST 1.1 or death from any cause, whichever occurs first, assessed up to 5 years]
Pathological response is assessed as the percentage of surface with non-viable cancer cells (represented by necrosis or fibrosis, the ultimate stage of necrosis) in relation to the total tumor area and will be equal to: 100% - viable cancer cells (%). If there are multiple tumors, the mean percentage will be used. Pathological complete response (pCR) is defined by the absence of viable tumor cells in any nodule.
