Hepatocellular Carcinoma Clinical Trial
— ARYA-3Official title:
An Open-Label, Dose Escalation, Multi-Center Phase I/II Clinical Trial of ECT204 T-Cell Therapy in Adults With Advanced Hepatocellular Carcinoma (HCC) (ARYA-3)
This is an open-label, dose escalation, multi-center, Phase I/II clinical trial aimed at assessing the safety and preliminary efficacy of an investigational ARTEMIS® ECT204 T-cell therapy. The trial is suitable for adult subjects (≥ 18 years of age) diagnosed with GPC3-positive HCC, who have failed or not tolerated at least two (2) different anti-HCC systemic agents. Phase I has concluded and a Recommended Phase II Dose (RP2D) has been determined. We are now conducting Phase II to further confirm the safety profile of ECT204 and evaluate its efficacy.

Eligibility | Inclusion Criteria: - Histologically confirmed HCC, which is unresectable, recurrent and/or metastatic. - GPC3-positive expression in HCC tumor cells confirmed by immunohistochemistry (IHC). To be eligible for Phase 2 (expansion phase) of the study, the subject's tumor biopsy sample (resection or needle core sample) must demonstrate that more than 50% of tumor cells exhibit at least 3+ GPC3 expression intensity. - Must have failed, or not tolerated, at least two (2) different anti-HCC systemic agents. - Life expectancy of at least 4 months per the Investigator's opinion. - Karnofsky Performance Scale of 70 or higher. - Measurable disease by RECIST v1.1. Previously treated lesions are allowed as long as there is a new confirmed measurable component. - Child-Pugh score of A6 or better. - Adequate organ function. Exclusion Criteria: - Pre-existing illness (e.g., symptomatic congestive heart failure) that would limit compliance with study requirements. - Active, uncontrolled systemic bacterial, fungal, or viral infection. Subjects with Human Immunodeficiency Virus (HIV), hepatitis B, or hepatitis C are eligible provided their infection is being treated and the viral load is controlled. - Active malignancy (other than HCC), with the exception of cholangiocarcinoma (CCA) or any malignancy without any organ involvement and with an expected survival = 3 years without any treatment (exception: hormone/androgen- deprivation therapy). - Currently receiving or ending (< 14 days from date of consent) liver tumor-directed therapy (e.g., radiation, ablation, embolization), or hepatic surgery. - Concurrently receiving other investigational agents, biological, chemical, or radiation therapies, while participating in the study. - Active autoimmune disease requiring therapy. - Compromised circulation in the main portal vein, hepatic vein, or vena cava due to obstruction. - History of organ transplant. - Advanced HCC involving greater than half (50%) of the liver. |

Primary | To assess the safety and tolerability of ECT204 in adult subjects with advanced HCC | The incidence rates of dose limiting toxicities (DLTs) and the type, frequency, and severity of adverse events (AEs) and laboratory abnormalities will be assessed by the number and severity rates after infusion of ECT204. | 28 days | |
Primary | To determine the Recommended Phase II Dose (RP2D) of ECT204 (Concluded During Phase 1 of the study) | The RP2D was determined by the study Dose Escalation Committee (DEC) and chosen based on the maximum tolerated dose (MTD) that did not exceed the MTD and the maximum administered dose (MAD). The RP2D was also based on the manufacturing capability. | 21 months - This outcome was completed on December 20, 2023 | |
Secondary | To assess the efficacy of ECT204 in adult subjects with advanced HCC using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (RECIST v1.1) as the primary criterion. | The response rate will be assessed by radiographic scans and assessed according to RECIST version 1.1. based upon the following:
Overall Response Rate (ORR), defined as the proportion of subjects with a best overall response (BOR) of either complete response (CR) or partial response (PR). Disease Control Rate (DCR), defined as the proportion of subjects with BOR of either CR, PR, or stable disease (SD). Duration of Response (DOR), defined as the time from first response to progressive disease (PD) or death. Progression-Free Survival (PFS), defined as the time from ECT204 infusion to PD or death. Overall Survival (OS), defined as the time from ECT204 T-cell infusion to the date of death. |
Up to 2 years | |
Secondary | To characterize the pharmacokinetic (PK) profile of ECT204, including the expansion and persistence of ECT204, in our study subject population | The peak exposure (Cmax), time to reach peak exposure (Tmax), partial area under the curve (pAUC) and other relevant PK parameters of ECT204 in peripheral blood (PB) will be measured. | Up to 2 years |
