ClinConnect Summary

This clinical trial is studying a new treatment called VG161 for patients with advanced intrahepatic cholangiocarcinoma, which is a type of liver cancer that has not responded to standard therapies. VG161 is an injectable medication that is given directly into the tumor using imaging guidance, like ultrasound or CT scans. The main goal of the study is to see if this treatment can effectively shrink the tumors or improve patients’ conditions.

To be eligible for this trial, participants need to be between 18 and 75 years old and have been diagnosed with advanced intrahepatic cholangiocarcinoma that has not improved with prior treatments. They should also be in relatively good health, meaning they have a certain level of organ function and can tolerate the treatment. This trial is currently looking for volunteers, and participants can expect to receive VG161 injections and be monitored closely for any changes in their condition. It’s important for potential participants to discuss this study with their healthcare provider to understand if it’s the right option for them.

Eligibility criteria

• Inclusion Criteria:
• • 1. Subjects must fully understand and give informed consent to this study before the trial, and voluntarily sign a written informed consent form.
• • 2. aged 18 to 75 years (inclusive), male or female. 3. patients with histologically or cytologically confirmed advanced intrahepatic cholangiocarcinoma.
• • 4. According to the Guidelines for the Diagnosis and Treatment of Biliary Malignant Tumors (CSCO), patients must have previously received at least systemic first-line therapy for advanced intrahepatic cholangiocarcinoma and failed, or cannot tolerate treatment. Patients who received preoperative neoadjuvant chemotherapy or postoperative adjuvant chemotherapy were counted as having failed first-line treatment if disease progression occurred during chemotherapy or within 6 months after stopping chemotherapy; 5. According to RECIST 1.1 criteria, one or more CT examinations are determined to be measurable and meet the requirements for the volume administered for the first injection, tumor lesions and/or metastases (the injected lesions should preferably be the main tumor burden lesions) that can be injected under ultrasound or CT guidance, and the baseline longest diameter of the injected lesions (lymph node lesions are short diameters) is \> 1.5 cm.
• • 6. Herpes simplex virus type I (HSV-1) antibody test results (HSV-1 IgG or HSV-1 IgM) are positive.
• 7. ECOG performance score 0-1. 8. Expected survival time of more than 3 months. 9.Adequate organ function:
• • 1. Blood routine (no blood transfusion or colony-stimulating factor treatment within 14 days): ANC ≥ 1.5 × 109/L, PLT ≥ 75 × 109/L, Hb ≥ 85 g/L;
• • 2. Liver function: TBIL ≤ 1.5 × ULN, ALT ≤ 3 × ULN, AST ≤ 3 × ULN;
• • 3. Child-Pugh A-B;
• • 4. Renal function: Cr ≤ 1.5 × ULN, and creatinine clearance ≥ 45ml/min (calculated according to Cockcroft-Gault formula);
• • 5. Coagulation function: activated partial thromboplastin time (APTT) ≤ 1.5 × ULN, prothrombin time (PT) ≤ 1.5 × ULN, international normalized ratio (INR) ≤ 1.5 × ULN; 10.Eligible patients of childbearing potential (men and women) must agree to use a reliable method of contraception (hormonal or barrier method or abstinence) during the trial and for at least 90 days after the last dose; female patients of childbearing potential must have a negative blood pregnancy test within 7 days prior to enrollment.
• Exclusion Criteria:
• • 1. received chemotherapy, radiotherapy, biological therapy, endocrine therapy, targeted therapy, immunotherapy and other anti-tumor drugs within 4 weeks before the first use of the study drug, of which oral fluorouracil and small molecule targeted drugs were within 2 weeks before the first use of the study drug or within 5 half-lives of the drug (whichever was longer).
• • 2. Patients who have received transcatheter arterial chemoembolization (TACE) within 4 weeks before the first use of the study drug.
• • 3. Received other clinical trial drugs that are not approved for marketing within 4 weeks before the first use of the study drug.
• • 4. Major organ surgery (excluding needle biopsy) or significant trauma within 4 weeks before the first dose of study drug.
• • 5. Have received a vaccine within 4 weeks prior to the first dose of study drug.
• • 6. Patients who have received systemic corticosteroids (prednisone \> 10 mg/day or equivalent doses of the same class of drugs) or other immunosuppressive agents within 14 days before the first dose of study drug; except for the following: topical, ocular, intra-articular, intranasal, and inhaled corticosteroids; short-term corticosteroids (≤ 10 mg prednisone equivalent) for prophylaxis (e.g., prevention of contrast agent allergy).
• • 7. The adverse reactions of previous anti-tumor treatment have not recovered to CTCAE 5.0 grade evaluation ≤ 1 (except alopecia and other toxicities that are judged by the investigator to have no safety risk); 8. Patients with central nervous system metastasis, spinal cord metastasis and/or spinal cord compression.
• • 9. in the herpes simplex virus recurrence and infection period, and there are corresponding clinical manifestations, such as oral herpes labialis, herpetic keratitis, herpetic dermatitis, genital herpes and so on.
• • 10. other active uncontrolled infections. 11. History of immunodeficiency, including positive HIV antibody test and positive Treponema pallidum antibody test.
• 12. Patients with active chronic hepatitis B or active hepatitis C. (Except hepatitis B virus carriers, hepatitis B virus stable after drug treatment \[HBV-DNA negative or \< 500 IU/ml\] and cured hepatitis C patients \[HCV RNA negative\]) 13. History of serious cardiovascular disease:
• • 1. Ventricular arrhythmia requiring clinical intervention;
• • 2. QTc interval \> 480 ms;
• • 3. Acute coronary syndrome, congestive heart failure, stroke or other Grade III and above cardiovascular events within 6 months before the first use of study drugs;
• • 4. New York Heart Association (NYHA) functional classification ≥ II or left ventricular ejection fraction (LVEF) \< 40%;
• • 5. Uncontrolled hypertension after treatment (judged by the investigator); 14. Patients with active, or have had and have the possibility of relapse of autoimmune diseases (such as systemic lupus erythematosus, rheumatoid arthritis, vasculitis, etc.); except for clinically stable autoimmune thyroiditis, autoimmune-mediated hypothyroidism treated with stable doses of thyroid replacement hormone, type I diabetes treated with stable doses of insulin, vitiligo or recovered childhood asthma/allergy, without any intervention in adults.
• • 15. Having received immunotherapy and have experienced immune-related adverse events (irAEs) such as immune-related pneumonia and myocarditis, which may affect the safety of the investigational drug as judged by the investigator.
• • 16. Known alcohol or drug dependence. 17. Patients with mental disorders or poor compliance. 18. Pregnant or lactating women. 19. The investigator believes that the subject has other serious systemic diseases or other reasons and is not suitable for this clinical study.
