Primary purpose: TREATMENT

Brief summary: The goal of this clinical trial is to evaluate the safety and efficacy of anti-GPC3 scFv-41BB-CD3ζ-tEGFR chimeric antigen receptor (CAR)-modified T (CAR-T) cells in treating patients with GPC3-positive advanced hepatocellular carcinoma (HCC).

Detailed description: Primary Objectives:

1. To evaluate the safety of intravenous administration of the anti-GPC3 CAR-T cells in patients with HCC or lung squamous cell carcinoma
2. To access the safety of anti-GPC3 CAR-T cells in HCC patients through catheter injection

Secondary Objectives:

1. To evaluate the efficacy of anti-GPC3 CAR-T cells in patients with advanced HCC or lung squamous cell carcinoma
2. To monitor the serum cytokine and expression level of tumor markers such as AFP, CEA and GPC3
3. To assess the persistence in peripheral blood and intratumoral infiltration of anti-GPC3 CAR-T cells

Eligibility criteria: Inclusion Criteria:

* Long-term use of immunosuppressive agents after organ transplantation
* Screening indicated that the target cell transfection rate was less than 30%
* Invasive pulmonary embolism, deep venous thrombosis, or other major arterial / venous thromboembolic events occurred 30 days or 30 days prior to randomization
* Subjects had an active or uncontrollable infection requiring systemic therapy 14 days or 14 days prior to randomization
* Pregnant or lactating subjects
* In the opinion of the investigator, the presence of a medical history or a history of mental state may increase the number of subjects associated with the risk factors associated with the study or study drug administration
* Subjects who have signed a written consent or who are in compliance with the study procedure; or who are unwilling or unable to comply with the study
