Clinical Trial Summary

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

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.
