About this trial

This study is a single-centre, single-arm, open-label, dose-escalation exploratory study with single-dose administration. Its objective is to evaluate the safety, tolerability, dose, anti-tumor efficacy, and pharmacokinetic characteristics of CG-102-12C in the participants with GPC3-positive advanced hepatocellular carcinoma who previously received adequate but uneffective systemic standard treatments.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

1. The study participant has fully understood the potential risks and benefits of participating in this study and has signed the informed consent form.

2. Aged 18-75 years (inclusive of 18 and 75 years old).

3. Patients with advanced hepatocellular carcinoma (HCC) confirmed by histopathological or cytological examination to be GPC3-positive (advanced HCC is defined as Barcelona Clinic Liver Cancer (BCLC) stage C or stage B that is unsuitable for or has progressed after local treatment, including ablation therapy, interventional therapy, and radiotherapy). Patients must have previously received systemic standard treatment and experienced treatment failure or intolerance (systemic treatments include, but are not limited to, chemotherapy and molecular targeted therapy). Treatment failure is defined as disease progression during or after the most recent treatment.

4. Immunohistochemical analysis of tumor tissue samples must show GPC3 positivity (defined as >25% of pathological specimens with IHC-detected GPC3-positive cells and staining intensity ≥1+). Preferably ,target lesion specimens will be used, including freshly obtained tumor pathology samples or archived tumor pathology samples deemed acceptable by the investigator.

Disqualifiers

1. History of a second primary malignancy is permitted, unless the patient has undergone potentially curative treatment and has been free of the disease for 5 years.

2. Prior treatment with CAR-T or TCR-T cell therapy targeting any antigen or therapeutic cancer vaccines; or prior treatment with any therapy targeting GPC3.

3. Prior to apheresis, the patient has received the following antitumor therapies: Cytotoxic therapy within 14 days; Small molecule targeted therapy, epigenetic therapy, or experimental drug therapy within 14 days or at least 5 half-lives (whichever is longer), or treatment with invasive experimental medical devices; Monoclonal antibody therapy within 21 days; Immunomodulatory therapy within 7 days; Radiotherapy within 14 days.

4. Toxicities from prior antitumor therapies have not recovered to ≤ Grade 1 according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE version 5.0), except for alopecia, Grade 2 peripheral neuropathy, and hypothyroidism controlled by hormone replacement therapy.
