Investigator-initiated Phase I Exploratory Clinical Study of the Safety, Tolerability, and Efficacy of BST02 Injection in the Treatment of Locally Advanced/Metastatic Liver Cancer
This is an open, single-arm, investigator-initiated Phase I clinical trial to evaluate the safety, tolerability, and initial efficacy of BST02 injection in patients with locally advanced / metastatic liver cancer. This study includes a dose escalation study and a dose extension study, which will observe the effects of different IL-2 injection doses on the safety and efficacy of BST02.
After signing the informed consent, the subjects will roughly go through two periods: the main study period and the long-term follow-up period. The main study period includes screening period, treatment and safety observation period, and follow-up period

Inclusion Criteria:

Hepatocellular carcinoma (HCC) and cholangiocarcinoma (BCLC) are either stage C or stage B that is not suitable for local treatment/local treatment progression according to Barcelona Clinic Liver Cancer (BCLC). Metastatic liver cancer is not suitable for radical surgical treatment according to the TNM stage of the primary cancer.
- For locally advanced liver cancer, guidelines should recommend at least first-line systemic therapy (atrilizumab + bevacizumab, sindilizumab + bevacizumab analogues; Donafenib, Renvastinib, sorafenib; FOLFOX4) after failure (disease progression or intolerance), or as determined by the investigator to be unsuitable, or the patient refused to receive the standard treatment recommended by the guidelines. For metastatic liver cancer, failure (disease progression or intolerance) of at least second-line treatment recommended by guidelines, or inappropriate treatment determined by the investigator, or refusal of standard treatment is required.
- At least one operation without radiation or other local treatment within 28 days to remove the tumor lesion with an estimated lesion volume of at least 8 cm^3, excluding necrotic areas, for the preparation of BST02 cells.

Adequate organ and bone marrow function in the assessment conducted during the screening period (within 14 days prior to TIL sampling), as defined below:

- Liver function: Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) levels ≤5× upper limit of normal value (ULN), Serum Total Bilirubin (TBil) ≤1.5×ULN, if diagnosed with Gilbert syndrome: TBil≤3×ULN.
- Coagulation function: Activated partial thromboplastin time (APTT) ≤1.5×ULN, while International Normalized Ratio, INR), Prothrombin Time (PT) ≤1.5×ULN.
- Renal function: Serum Creatinine (Cr) ≤1.5×ULN or Creatinine Clearance (Ccr) ≥60 mL/min (Cockcroft-Gault formula).
- Cardiac function examination: Left ventricular Ejection Fraction (LVEF) ≥50% by echocardiography; No arrhythmias requiring treatment, Fridericia QT correction formulas (QTcF) ≤470 ms (QTcF is calculated using Fridericia's formula, That is, QTcF = QT/ (RR^0.33), RR is the standardized heart rate value, RR=60/ heart rate; If the first check is abnormal, the interval of at least 5 minutes, retest twice, take the comprehensive result/average value to judge the conformity);
- Lung function: FEV1 percentage of predicted value (FEV1%) ≥60%.
- Prior to tumor sampling, the adverse reactions caused by previous treatment had returned to the Common Adverse Event Evaluation Criteria (CTCAE) 5.0≤1 (except for alopecia, peripheral neurotoxicity of grade 2 or below, and other toxicities that the investigators judged to have no safety risk).
- Consent to take effective contraceptive measures within 6 months from the signing of informed consent to TIL cell transfusion (subjects must use non-drug contraceptive measures).
Those who fully understand the test and voluntarily sign the informed consent and can comply with the visit and related procedures stipulated in the program.

Exclusion Criteria:
- Pregnant or lactating women.
- Subjects with a history of severe allergy to the experimental drugs including but not limited to cyclophosphamide, fludarabine, IL-2, and TIL injection components.

- There is currently clinically significant ascites, which are defined as ascites with positive signs of ascites in physical examination or requiring intervention treatment (only those who show ascites on imaging without intervention can be included).
- The proportion of liver occupied by tumor ≥50%, or ICG-R15≥30%.
- Organ transplantation, hematopoietic stem cell transplantation history;
Other serious medical conditions that may limit participants' participation in the study, including but not limited to:

- Use of any immunosuppressive drugs, such as corticosteroids, in the 4 weeks prior to the tumor tissue sampling, or the presence of co-existing diseases that the investigator determined required the use of immunosuppressive drugs during the trial. However, the use of physiological doses of corticosteroids (i.e., no more than 15mg/ day of prednisone or equivalent doses of other corticosteroids) is permitted, and the use of corticosteroids for inhalation, intranasal, topical or prophylactic use of contrast media allergies is permitted.
- Anti-tumor therapy was received before pretreatment, including anti-PD-1 / PD-L1 monoclonal antibodies, targeted drugs, chemotherapy, surgery, etc., and the last administration/treatment distance from pretreatment was less than 2 weeks. Or the above treatment-related adverse events, CTCAE classification does not return to grade 1 or stable.

Experimental: BST02 Injection
|
The TIL used for tumor tissue surgical sampling of qualified subjects was used to prepare BST02 injection, and the subjects who successfully received the surgical sampling were considered to be enrolled. In the study process, cell transfusions were recorded as day 0 of the study. On the 3rd day (D-3) before infusion of BST02 injection, it is necessary to receive eluvial pretreatment. Considering that this product is unmodified autologous T lymphocytes, previous studies have shown that low-intensity cyclophosphamide can stimulate their proliferation in vivo. Therefore, the cyclophosphamide (Cy) single-drug regimen is recommended: Cy 250mg~1.5g/m2, a single intravenous infusion |
