A Study of LioCyx in Patient With Recurrent HBV-related HCC Post Liver Transplantation
- Conditions
- Recurrent Hepatocellular Carcinoma
- Registration Number
- NCT03634683
- Lead Sponsor
- Lion TCR Pte. Ltd.
- Brief Summary
Hepatocellular carcinoma (HCC) represent approximately 70-85% of liver cancer, in which Hepatitis B virus (HBV) is the major etiologic agent accounting for at least 80% of HCC in Asian countries. Overall, transplantation remains the best option however, HCC recurrence rate is high among liver transplant patients.
While there are limited treatment measures for HBV-related HCC recurrences, the study hypothesized that LioCyx is capable of lysing target liver cells expressing the HBV cognate antigens and provide clinical benefit to patients with HBV-related HCC.
- Detailed Description
The study is a Phase I/II, open label, single-arm, multicenter study of LioCyx. Subjects with recurrent hepatitis B virus-related hepatocellular carcinoma who undergone liver transplantation will be enrolled.
Approximately 6-12 subjects will be enrolled in Phase 1 dose regimen exploration, and approximately 60 subjects will be enrolled to characterize the safety and evaluate the efficacy of LioCyx"
All subjects will be followed up for survival until death.

Study & Design
- Study Type
- INTERVENTIONAL
- Study Design
- SINGLE_GROUP
- Primary Outcome Measures
Name Time Method Safety based on Incidence of Treatment-Emergent Adverse Events (AEs) and Serious AEs Start of Treatment until 28 days post last dose Review the safety profile of LioCyx by assessing the incidence of AEs and SAEs
- Secondary Outcome Measures
Name Time Method Overall Response Rate Start of Treatment until first documented CR or PR, assessed up to 62 treatment weeks (protocol-defined treatment duration is until disease progression, death, or loss to follow up, whichever came first) Tumor assessment will be according to mRECIST. This is based on percentage of participants with Complete Response (CR) and Partial Response (PR) according to mRECIST from baseline.
Quality of life of patients Baseline to 28 days post treatment (end of treatment) Compare the quality of life of patients based on \[Functional Assessment of Chronic Illness Therapy- Hepatobiliary (FACIT-Hep), version 4\]
Overall Survival according to mRECIST Start of Treatment until first protocol-defined PD, and survival follow up until death, assessed up to 62 treatment weeks (protocol-defined treatment duration is until disease progression, death, or loss to follow up, whichever came first) Assess the efficacy following LioCyx in prolonging overall survival of patients in HBV-related HCC patients
