Brief summary

To evaluate the safety, tolerability and efficacy of autologous γδT cells in the treatment of advanced hepatitis B-related hepatocellular carcinoma.

Detailed description

This is a single-centre, non-randomised, open label, no control, prospective clinical trial. The study will include the following sequential phases: sign informed consent, γδT cells pre-culture, fresh biopsy and screening, apheresis, γδT cells preparation, treatment and follow-up. The study will evaluate the safety, tolerability and efficacy of autologous γδT cells in patients with advanced hepatitis B related hepatocellular carcinoma (HCC) which are refractory to current treatment. Stage I comprising a safety cohort of patients to identify a safe dose, Stage II comprising an expanded patient group for response signal identification, Stage III to confirm efficacy and safety.

Interventions

Cells will be extracted by apheresis, followed by expanding and activating. The autologous γδT cells product will be adoptive transferred.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of adverse events (AEs) and serious adverse events (SAEs)14 monthsIncidence of adverse events (AEs) and serious adverse events (SAEs) of each patient will be recorded and analyzed.
Overall survival (OS)14 monthsOverall survival is defined as the time from the day in which the patient is enrolled to the date on which the patient dies for any cause.

Secondary

MeasureTime frameDescription
Objective Response Rate (ORR)14 monthsThe objective response rate (ORR) is defined as the proportion of patients who achieve radiographic partial or complete response (PR or CR) according to the response evaluation criteria in solid tumors (RECIST) guideline.
Patients-based Quality of Life Evaluation14 monthsAccording to the European Organization for Research and Treatment of Cancer (EORTC) quality of life of the core scale criteria QLQ-C30 to evaluate and compare patients life quality before and after treatment.
