Dual-Target GPC3/B7-H3 CAR-NK Cells for Advanced HCC

open-label trial of an allogeneic dual-target CAR-NK product directed against GPC3 and B7-H3 for adults with advanced hepatocellular carcinoma. The design intentionally uses GPC3 as the primary target anchor because GPC3 is the dominant HCC cell-therapy antigen in current clinical development, while adding B7-H3 to reduce antigen escape and to broaden coverage across tumor and tumor-microenvironment compartments. The study first evaluates safety and dose-limiting toxicities, then expands at the recommended phase 2 dose.

T-Cell Therapy (ECT204) in Adults With Advanced HCC

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.

68Ga-PSMA-11 PET-directed Radioligand Therapy in Metastatic Hepatocellular Carcinoma (HCC)

The purpose of this study is to look at the effects (good and bad) of a drug called 177Lu-PSMA-617 (also known as the study drug) when given to participants who have prostate specific membrane antigen (PSMA) positive liver cancer.

A Phase 1 Trial of ERX-315 in Participants With Advanced Solid Tumors

This is a Phase 1 study to assess the safety of ERX-315 in patients with advanced solid tumors that have failed approved systemic therapies.

Streamlining Radioembolization for CCC and Metastatic Liver Cancer

TARE uses radioactive microspheres (20-60 μm), which are trapped in tumors due to abnormal vasculature, while normal liver sinusoids (≤15 μm) prevent their passage. However, some microspheres may drain into hepatic veins and reach the lungs, risking radiation pneumonitis. Pre-procedural evaluation with angiography and nuclear imaging (MAA scan with SPECT/CT) is required to calculate lung shunt fraction (LSF). TARE is contraindicated if LSF \>20%, and may be used with caution if LSF is 10-20%. Findings associated with high LSF include large tumors, hepatic vein invasion, TIPS, and dysmorphic intratumoral vessels. In contrast, small or medium sized (\<7 cm) cholangiocarcinoma or metastatic liver cancers without hepatic vein invasion or dysmorphic vessels show consistently low LSF (\<5%). Over 10 years at SNUH, no cases of radiation pneumonitis have been observed in such patients. Therefore, "streamlining TARE" omits pre-procedural nuclear imaging for this group to reduce procedural delays, reserving nuclear imaging for patients who need it most. SIR-Spheres (SIRTEX) facilitate single-session TARE as they are provided in a bulk vial, unlike TheraSphere which requires advance preparation based on dosimetry. Protocol Overview : Procedure: Same-day angiography, cone-beam CT, and TARE using SIR-Spheres. Dosimetry: Lung shunt fraction is assumed as 5%, estimated lung dose is capped at 10 Gy. Tumor dose goal: 80\~400 Gy (around 250Gy)(single-compartment MIRD), or 300 \~ 1000 Gy (multi-compartment MIRD). minimal tumor dose by partition dosimetry : 100Gy Software: Simplicit90Y for planning, Y90 PET/CT the next day for post-treatment dosimetry. Follow-up: 1 year; additional treatments follow institutional guidelines. This streamlined approach maximizes efficiency while maintaining safety in selected patients.

ET140203 T Cells in Pediatric Subjects With Hepatoblastoma, HCN-NOS, or Hepatocellular Carcinoma

Open-label, dose escalation, multi-center, Phase I/II clinical trial to assess the safety/tolerability and determine the recommended Phase II Dose (RP2D) of ET140203 T-cells in pediatric subjects who are AFP-positive/HLA-A2-positive and have relapsed/refractory HB, HCN-NOS, or HCC.

Liver Transplantation in Patients With Unresectable Colorectal Liver Metastases

Multicentric prospective and observational study to assess the 5-year overall survival in a cohort of patients with unresectable liver-only colorectal metastases, well controlled by chemotherapy prior to liver transplantation.

PDO/PDO-TIL/PDOTS for Drug Screen

This clinical trial aims to use the patient-derived organoid (PDO), Patient-derived organoids-tumor-infiltrating lymphocyte coculture system (PDO-TIL) and patient-derived organotypic tissue spheroids (PDOTS) to simulate the tumor microenvironment in cancer patients. The culture system can be used for pre-clinical validation of drugs and screening of drugs to treat sensitive people and provide individualized treatment for patients with liver cancer. This model is used to explore the molecular mechanism of drug resistance and to find intervention strategies to further improve the response rate of drugs. This study is expected to provide an ideal platform for drug screening and drug resistance research in liver cancer patients, which can replace experimental animal models, and guide personalized medication for liver cancer patients, so as to improve the overall prognosis of patients.

Anti-CEA CAR-T Cells to Treat Colorectal Liver Metastases

Recurrence of liver metastasis in colorectal cancer after R0 resection is mainly due to the invisible minimal residual disease, which are the main factors leading to metastasis and recurrence. Positive circulating tumor DNA (ctDNA) is the direct evidence of the minimal residual disease (MRD). In recent years, Chimeric Antigen Receptor T-Cell Immunotherapy (CAR-T) has made great breakthroughs, and has achieved good therapeutic effects in hematological tumors, but the research on solid tumors is limited. CEA expression is generally elevated in gastrointestinal tumors and is associated with high aggressiveness of tumors. At present, solid tumor cell therapy targeting CEA has been carried out at home and abroad, and has achieved certain efficacy. Anti-CEA CAR-T cells targeting CEA have been constructed in the pre-clinical study of this project, and the pre-clinical study results suggest good safety and effectiveness. Formation of minimal residual disease is associated with circulating blood in the residual tumor cells. Using this feature, this project intends to conduct a phase I clinical study on patients with minimal residual disease /positive ctDNA after R0 resection of colorectal cancer liver metastasis, so as to conduct preliminary exploration of anti-CEA CAR-T cell therapy, evaluate the safety and effectiveness of the therapy, determine the maximum tolerated dose (MTD), and provide guidance for subsequent drug dosage and clinical trials.
