ClinConnect Summary

This clinical trial is studying a new treatment called VG161 for patients with advanced primary liver cancer who have not responded well to standard therapies. The trial is divided into two parts. In the first part, researchers are trying different doses of VG161 to see how safe it is and to determine the best dose to use. In the second part, they will focus on how effective VG161 is in treating the cancer.

To participate in this trial, patients must have specific types of advanced liver cancer and meet certain health criteria, such as having a life expectancy of at least three months and proper organ function. Participants can expect to receive VG161 through injections, and they will be monitored closely throughout the study to ensure their safety. It's important to note that patients who have had recent treatments or certain health conditions may not be eligible for this trial.

• • 6. Subjects who are HBV-DNA negative; or HBV-DNA positive are required to receive treatment in accordance with the 'Guidelines for the prevention and treatment of chronic hepatitis B' (2019 Edition) or clinical practice.
• • 7.Subjects of childbearing potential (male and female) must agree to use a reliable contraceptive method (hormone or barrier method or abstinence) during the study and for at least 90 days following the last dose; females of childbearing potential must have a negative blood pregnancy test within 7 days of study enrollment.
• • 8.Signed written informed consent.
• Exclusion Criteria:
• • 1. Subject in prior anti-tumor therapies such as chemotherapy, radiotherapy, biotherapy, endocrinotherapy, targeted therapy, immunotherapy within 4 weeks of study treatment initiation. Oral fluorouracil analogues and small molecule targeted drugs were 2 weeks prior to the first dose of study drug or within 5 half-lives of the drug (whichever was longer).
• • 2. Transcatheter arterial chemoembolization(TACE) within 4 weeks of study treatment initiation
• • 3. Participation in clinical trials of any other investigational agents within 4 weeks of study treatment initiation.
• • 4. Major organ surgery (excluding puncture biopsy) or significant trauma within 4 weeks of study treatment initiation.
• • 5. Patients who received systemic treatment with either corticosteroids ( \>10 mg/ daily prednisone or equivalent) or other immunosuppressive medications within 14 days of study treatment initiation.
• • 6. Subjects with any ≥Grade 1 toxicity (as per NCI CTC AE Version 5.0) related to prior anti-cancer therapy (except for toxicity that the investigator assessed to be no safety risk, such as alopecia.).
• • 7. Subjects with Central Nervous System (CNS) metastasis or meningeal metastasis .
• • 8. Seronegative for Herpes Simplex Virus (HSV) (HSV-1IgG and HSV-1IgM).
• • 9. Subjects with the relapse of HSV infection and relevant clinical manifestations, such as lip herpes, herpes keratitis, herpes dermatitis, and genital herpes.
• • 10. Subjects with other uncontrolled active infections.
• • 11. Known history of immunodeficiency and test positive of human immunodeficiency virus (HIV).
• 12. History of severe cardiovascular disease:
• • 1)Ventricular arrhythmias requiring clinical intervention; 2)QTc interval \>480 ms; 3)Acute coronary syndrome, congestive heart failure, stroke or other cardiovascular events of III grade or above within 6 months; 4)The cardiac function grade≥II or left ventricular ejection fraction (LVEF) \<50% per the New York Heart Association (NYA); 5)Uncontrolled hypertension.
• • 13. Subjects with active or past autoimmune diseases that are likely to recur (e.g. systemic lupus erythematosus, rheumatoid arthritis, vasculitis, etc.); acceptable for patients with clinically stable autoimmune thyroiditis.
• • 14. Previous immunotherapy with an immune-related adverse event (irAE) such as immune-related pneumonia, myocarditis, etc., which, in the judgement of the investigator, may affect the safety of the investigational drug. 15. known to have alcohol or drug dependence. 16. Persons with mental disorders or poor compliance. 17. Pregnant or lactating women. 18. Subjects with any significant unrelated systemic illness that to the investigator's opinion would compromise the subject's eligibility to participate the study.
