Purpose
This is a open-label, dose escalation, multi-center, Phase I / Phase II study to assess the
safety of an autologous T-cell product (ET140202) in adult subjects with advanced
Alpha-fetoprotein (AFP) positive/Human Leukocyte Antigen (HLA) A-2 positive Hepatocellular
Carcinoma (HCC).
Detailed Description
The purpose of this study is to investigate a genetically modified autologous T-cell therapy
for advanced hepatocellular carcinoma (HCC). ET140202 T cells are autologous T cells
genetically modified to carry a TCR-mimic (TCRm) construct capable of mediating cell killing
by targeting tumor specific intracellular antigens and addressing solid tumor therapy
challenges.

Primary Outcome Measures
Measure: | Incidence rates of adverse events (AEs) after infusion of ET140202 T cells |
Time Frame: | 28 days |
Safety Issue: | |
Description: | Safety and tolerability of ET140202 T cells as assessed by committee review of dose limiting toxicities (DLTs) and incidence and severity of adverse events (AEs) after infusion |
Secondary Outcome Measures
Measure: | Assess efficacy of ET140202 T cells by overall response rate (ORR) using Response Evaluation Criteria In Solid Tumors (RECIST). |
Time Frame: | up to 2 years |
Safety Issue: | |
Description: | As a measure of activity, overall response rate will be assessed by radiographic scans and assessed according to RECIST criteria. |
Measure: | Assess efficacy of ET140202 T cells by complete response (CR) using Response Evaluation Criteria In Solid Tumors (RECIST). |
Time Frame: | up to 2 years |
Safety Issue: | |
Description: | As a measure of activity, CR rate will be assessed by radiographic scans and assessed according to RECIST criteria. |
Measure: | Assess efficacy of ET140202 T cells by partial response (PR) using Response Evaluation Criteria In Solid Tumors (RECIST). |
Time Frame: | up to 2 years |
Safety Issue: | |
Description: | As a measure of activity, PR rate will be assessed by radiographic scans and assessed according to RECIST criteria. |
Measure: | Assess efficacy of ET140202 T cells by progression-free survival (PFS) using Response Evaluation Criteria In Solid Tumors (RECIST). |
Time Frame: | up to 2 years |
Safety Issue: | |
Description: | As a measure of activity, PFS rate will be assessed by radiographic scans and assessed according to RECIST criteria. |
Measure: | Assess efficacy of ET140202 T cells by overall survival (OS) using Response Evaluation Criteria In Solid Tumors (RECIST). |
Time Frame: | up to 2 years |
Safety Issue: | |
Description: | As a measure of activity, OS rate will be assessed by radiographic scans and assessed according to RECIST criteria. |
Measure: | Assess the expansion of ET140202 T cells in the blood shortly after infusion. |
Time Frame: | up to 2 years |
Safety Issue: | |
Description: | The maximum (peak) expansion of ET140202 T cells in the blood post infusion will be determined. |
Measure: | Assess the persistence of ET140202 T cells circulating in blood over time. |
Time Frame: | up to 2 years |
Safety Issue: | |
Description: | The level of ET140202 T cells in blood will be determined to assess the persistence of ET140202 T cells during the treatment and follow-up phases of the study. |
