简要总结
This is a dose escalation Phase 1 clinical study to evaluate the safety and immunogenicity of Glypican3 (GPC3)-targeted DNA plasmid vaccine (NWRD06) in patients with GPC3-positive primary hepatocellular carcinoma after radical resection.
详细描述
This study is divided into three dose groups:1mg, 4mg, and 8mg. Each patient will be administered NWRD06 by electroporation in entire study period. The Maximum tolerated dose of NWRD06 will be determined by the classical 3+3 dose escalation schedule. The number of patients will be ranged from 9 to 18.
After the completion of treatment, the subjects shall continue to receive safety follow-up until 28 days after the last administration.
Immunologic reactogenicity in blood samples was assessed at week 0, week 2, week 4, week 6, week 8, week 10, week 12.
Peripheral blood samples were then collected every 3 months for immunogenicity assessment until disease progression or specific immune response became undetectable or the study was withdrawn for various reasons or ended (whichever occurred first).

- •No residual intrahepatic tumor was found by imaging examination within 4 weeks before the first NWRD06 administration; No lymph node metastasis, no extrahepatic metastasis;
- •Patients undergoing radical resection of liver cancer should meet the intraoperative criteria of radical resection of liver cancer:1)There was no invasion of adjacent organs, hilar lymph nodes or distant metastasis during the operation; 2) Negative cutting margin;
- •No Vp4 macrovascular invasion, hepatic vein or inferior vena cava macrovascular invasion of any grade after radical resection; Notes: Patients with VP1, VP2 and VP3 macrovascular invasion diagnosed via histopathologic examination or imaging test meet the inclusion criteria.
- •Within 1 week before the first NWRD06 administration, ECOG performance status score was 0-1;
- •Child-Pugh score A/B (≤7) within 1 week before the first NWRD06 administration;
- •Major organ functions were normal within 1 week before the first NWRD06 administration: 1) Blood routine: Hemoglobin (Hb) ≥90 g/L; Platelet count (PLT) ≥75×109/L; 2) The liver: Total bilirubin (TB) ≤3× upper limit of normal (ULN); Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤5×ULN; Plasma albumin ≥30g/L; 3)Kidney: Serum creatinine (Scr) ≤1.5×ULN, or creatinine clearance ≥40 mL/min (serum creatinine > 1.5 x ULN);
- •The expected survival time is more than 6 months;
- •Patients with non-viral primary HCC meet the inclusion criteria. For patients with Hepatitis B virus-related primary HCC(HBV-HCC) or Hepatitis C virus-related primary HCC(HCV-HCC), antiviral therapies should be carried out simultaneously;
- •Within 1 week before the first NWRD06 administration, women of childbearing age must have a negative serum pregnancy test and consent to use effective contraception during the use of the study drug and within 6 months after the last administration of the study drug. For men, they should be surgically sterilized or agree to use effective contraception during study drug use and for 6 months after the last administration of study drug.
- •Have fully understood the study and voluntarily signed the ICF, have good communication with the investigator, and are able to complete all treatments, examinations, and visits stipulated in the study protocol.
排除标准
- •Patients with any of the following were excluded from the study:

- •Accompanied by hepatic encephalopathy;
- •Regular renal dialysis is required;
- •with uncontrolled pleural effusion, pericardial effusion, or moderate or more ascites (refers to ascites that cannot be easily controlled by diuretic treatment);
- •A history of gastrointestinal bleeding, current active bleeding, or bleeding tendency within 28 days before screening;
- •Had received systemic antitumor therapy (including chemotherapy, molecular targeted therapy, biological immunotherapy) for liver cancer within 28 days before screening;
- •Participated in another clinical trial or was under observation in another clinical trial within 28 days prior to screening;
- •Continuous (more than 1 week) glucocorticoid therapy (dose equivalent to prednisone > 10 mg/ day), except hormone replacement therapy and intratracheal administration;
- •A history of immune deficiency or autoimmune diseases (e.g., rheumatoid joint disease, systemic lupus erythematosus, multiple sclerosis, etc.);
- •A history of allogeneic stem cell/tissue/solid organ transplantation (including bone marrow transplantation);
- •With uncontrolled severe infection (> grade 2 NCI-CTCAE adverse events, version 5.0);
- •Patients with a history of human immunodeficiency virus (HIV) infection or carriers of syphilis;
- •Patients with serious other organ dysfunction or cardiopulmonary diseases;
- •Epilepsy that requires treatment with medication (e.g. steroids or antiepileptic drugs);
- •Had or currently has other malignancies (with the exception of adequately treated and completely cured ductal carcinoma in situ of the breast, carcinoma in situ of the cervix, basal cell carcinoma of the skin, superficial bladder tumor, or any malignancy that was cured more than 5 years before study entry);

- •Patients deemed by the investigator to be ineligible for this clinical trial.
结局指标
主要结局
Dose-limiting toxicity (DLT)
时间窗: From first administration of NWRD06 to 28 days after the last administration
It would be determined based on the rate and severity grade of events or abnormalities through evaluating systemic or local adverse events, clinical laboratory test results, vital signs that is definitely, probably, or possibly related to the test drug occurring within 28 days of the last dosing will be classified as DLT during dosing climb.
All adverse events (AE)
时间窗: 12 weeks
All adverse events (AE) will be determined based on the rate and severity grade of events, including incidence and severity of serious adverse events (SAE) (according to NCI-CTCAE Standard version 5.0 of common Terms for Adverse Events)
次要结局
- Immunogenicity(At week 0, week 2, week 4, week 6, week 8, week 10, week 12 and then collected every 12 weeks until disease progression or specific immune response became undetectable or the study was withdrawn for various reasons or ended (whichever occurred first).)
