This is an open-label, multi-center clinical study to evaluate the safety, tolerability and effectiveness of SCG101, with and without PD-1/PD-L1 checkpoint inhibitors, in patients with HBV-related HCC. Lymphodepleting regimen of cyclophosphamide and fludarabine will be given prior to SCG101 infusion.
Adoptive cell therapy with TCR-T cells targeting HBV antigens represents an innovative opportunity for treatment of HBV-related HCC. SCG101 is a genetically modified autologous TCR-T cell therapy with a natural high-avidity TCR directed towards the HLA-A*02-restricted HBsAg peptide. This is a phase 1 clinical study of SCG101 alone and with PD-1/PD-L1 checkpoint inhibitors in HBV-related HCC.
