A Study of LioCyx in Patient With Recurrent HBV-related HCC Post Liver Transplantation

Phase 1
Withdrawn
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
NameTimeMethod
Safety based on Incidence of Treatment-Emergent Adverse Events (AEs) and Serious AEsStart 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
NameTimeMethod
Overall Response RateStart 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 patientsBaseline 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 mRECISTStart 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
