Brief Summary

The vast majority of liver cancers have an insidious onset and are often asymptomatic in the early stages, making early diagnosis difficult. Once diagnosed, most liver cancers have reached locally advanced stages or distant metastases, equivalent to Barcelona stage (BCLC) C-D. The tumors progress rapidly and there is a lack of effective treatments. The survival period of cancer patients is generally only 3-6 months. Cellular immunotherapy, including CAR-T and TCR-T, is considered a new hope for the treatment of cancer. The purpose of this study is to explore the safety of QY-1-T (a TCR-T targeting HBV) in the treatment of HBV-related liver cancer, and to preliminarily evaluate the efficacy of QY-1-T in patients with HBV-related advanced liver cancer.

Eligibility Criteria

Inclusion Criteria: 1. Subjects aged 18-75 years old (male or female) 2. The subject voluntarily participate and have the ability to sign the informed consent independently 3. Patient with advanced hepatocellular carcinoma (HCC) confirmed by histopathology or cytology (BCLC stage B and C, or CNLC stage IIA/IIB and IIIA/IIIB). One of the following four conditions applies:a. Patients with advanced hepatocellular carcinoma (HCC) who are not candidates for surgery or local therapy and have previously failed or become intolerable after at least second-line or higher standardized systemic therapy (including but not limited to targeted therapy, immunotherapy, or chemotherapy) and whose disease progression or intolerance has been determined by imaging examination during or after treatment, Or patients whom the investigator believes could benefit. b. HCC patients with clinically confirmed recurrence or progression after local treatment, and the interval between treatment and enrollment is at least 4 weeks. c. HCC recurrence after resection progresses or is not tolerated by systemic therapy or TACE/HAIC or radiofrequency ablation, and the interval between treatment and entrainment is at least 4 weeks. d.
