Brief Summary

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.

Conditions

Hepatocellular Carcinoma

Keywords

Hepatocellular Carcinoma; Naked DNA Vaccine; GPC3

Outcome Measures

Primary Outcomes (2)

• Dose-limiting toxicity (DLT)

  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.

  From first administration of NWRD06 to 28 days after the last administration

• All adverse events (AE)

  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)

  12 weeks

Secondary Outcomes (1)

• 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collected every 12 weeks until disease progression or specific immune response became undetectable or the study was withdrawn for various reasons or ended (whichever occurred first).

Study Arms (1)

NWRD06 by electroporation

EXPERIMENTAL

Patients will be assigned to 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.

Biological: 1mg NWRD06 administered by electroporation; Biological: 4mg NWRD06 administered by electroporation; Biological: 8mg NWRD06 administered by electroporation

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.

You may not qualify if:

• Patients with any of the following were excluded from the study:

Model Details: This study is divided into three dose groups climbed from low-dose group to high-dose group in turn according to the 3+3 dose escalation principle. Three dose groups were preset in this study: dose group 1 and low-dose group \[a single dose of 1mg was administered three times at week 0, 4 and 8, respectively, with cumulative administration of 3mg\]; Dose group 2, middle-dose group \[single dose of 4mg, administered 3 times at week 0, 4, 8, respectively, cumulative administration of 12mg\]; Dose group 3, high-dose group \[a single dose of 8mg, administered at week 0, 4 and 8, a total of 3 times, cumulative administration of 24mg\]. After the completion of treatment, the subjects shall continue to receive safety follow-up until 28 days after the last administration.
