About this study

Official title: A Study to Assess the Safety, Feasibility, and Immunogenicity of Personalized Neoantigen-based Dendritic Cell Vaccine in Combination With Microwave Ablation to Treat Hepatocellular Carcinoma

This is a single-center, open-label, non-randomized, parallel-group phase 1 study evaluating a personalized neoantigen-based dendritic cell vaccine following microwave ablation in patients with hepatocellular carcinoma. After receiving information on both treatment options, eligible participants selected, according to their preference, either microwave ablation followed by Neo-DC vaccination or microwave ablation alone

Being tested
Neoantigen Vaccines, Microwave Ablation

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Neoantigen VaccinesBiological

    Also called Personalized Neoantigen-based Dendritic Cell Vaccine

    HCC (3cm≤D ≤5 cm, fewer than three tumors) patients were treated with Microwave Ablation and 7 courses of neoantigen-based DC vaccines.The first neoantigen-based DC vaccine injection will take place up to 30 days following the completion of Microwave Ablation. The day of the first vaccine injection will be referred to as Day 1.The schedule of vaccination is Day 1, Day 8, Day 15, Day 22, Day 50, Day78, Day106.

  • Microwave AblationProcedure or surgery

    ALL the HCC patients will be treated by Microwave Ablation.

Study groupRoleWhat they receive
Microwave Ablation + Neoantigen VaccinesExperimentalThe HCC patients will be treated firstly by Microwave Ablation, and then treated by courses of Neoantigen Vaccines.
Receives: Biological: Neoantigen Vaccines; Procedure: Microwave Ablation
Microwave AblationActive comparatorThe HCC patients will be treated only by Microwave Ablation.No vaccine will be used.
Receives: Procedure: Microwave Ablation

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety of neoantigen-based DC vaccine as measured by the number of subjects experiencing each type of adverse event according to the National Cancer Institute Common Terminology Criteria for Adverse Events v4.0.

    Measured: 1 years

Secondary outcomes (3)
  1. Immunogenicity of the neoantigen-based DC vaccine as measured by the frequency of antigen -specific T cells using ELISPOT analysis and ICS analysis.

    Measured: 2 years

  2. Number of participants alive at 2 years

    Measured: 2 years

  3. Progression-free survival at 2 years

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Neoantigen Vaccines and Microwave Ablation in people with Hepatocellular Carcinoma and Liver Cancer, Adult, run by Chinese PLA General Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety of neoantigen-based DC vaccine as measured by the number of subjects experiencing each type of adverse event according to the National Cancer Institute Common Terminology Criteria for Adverse Events v4.0. (time frame: 1 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Aug 2026.
