Conditions

Chronic Hepatitis b

Brief summary

This is a open-label study to evaluate the safety and efficacy of autologous T-cells transfected with messenger ribonucleic acid (mRNA) encoding Hepatitis-B virus (HBV) antigen specific T cell receptor (TCR) in combination with nucleos(t)ide analogues (NAs) in HBeAg-positive and negative chronic hepatitis B patients.

Interventions

BIOLOGICALLioCyx-M

Each patient will receive LioCyx-M infusion every one or two weeks, while continuing their existing nucleos(t)ide analog treatment.

Inclusion criteria

* CHB infection (Serum HBsAg-positive for ≥ 6 months) * Serum HBeAg-positive or negative * HLA class 1 profile matching HLA-class I restriction element of the available T cell receptors (restricted by either HLA-A\*02:01, A\*11:01 or A\*24:02). * Liver biopsy, Fibroscan or equivalent test obtained within the past 6 months demonstrating liver disease consistent with chronic HBV infection without evidence of bridging fibrosis or cirrhosis (≥Metavir 3).

Exclusion criteria

* History or other evidence of chronic liver disease unrelated to HBV infection (e.g., hemochromatosis, autoimmune hepatitis, alcoholic liver disease, toxin exposure, thalassemia, non-alcoholic fatty liver disease) * Decompensated liver function, such as Child-Pugh grade B or C, or clinical signs of decompensated liver function like ascites and varices * Positive HIV test result * History or suspected diagnosis of hepatocellular carcinoma, or AFP at screening \> 20 ng/mL (if AFP \> 20 ng/mL, a liver scan result is required to exclude hepatocellular carcinoma)
