Trial summary

The therapeutic options for HCC include hepatectomy, liver transplantation, local ablation therapy, transarterial chemoembolization (TACE), radiotherapy, and systemic therapy. However, as early-stage HCC often presents with no obvious symptoms or atypical clinical manifestations, over 80% of patients are diagnosed at… Read more about this study

About this study

The therapeutic options for HCC include hepatectomy, liver transplantation, local ablation therapy, transarterial chemoembolization (TACE), radiotherapy, and systemic therapy. However, as early-stage HCC often presents with no obvious symptoms or atypical clinical manifestations, over 80% of patients are diagnosed at an advanced stage, losing the opportunity for surgical resection and leaving liver transplantation as the only potentially curative option. Nevertheless, even after liver transplantation, the recurrence rate of HCC remains as high as 30-45%. In recent years, with the successive launch of novel targeted drugs and immune checkpoint inhibitors, Chinese patients with HCC have gained more treatment options for both disease management and recurrence prevention. However, given the heterogeneity of HCC, only a subset of patients benefit from these therapies.

Hepatitis B virus (HBV) infection is the primary risk factor for HCC, accounting for at least 50% of global HCC cases. In regions with high HBV prevalence-such as East and Southeast Asia, as well as sub-Saharan Africa-the proportion is even higher. While HBV-related HCC can be prevented through vaccination against HBV infection, no specific precision therapy currently exists for patients already diagnosed with HBV-positive HCC. Given that nucleic acid vaccine technology demonstrates value not only in disease prevention but also in immunotherapy-particularly mRNA therapeutic vaccines-this approach holds promise.

mRNA therapeutic vaccines represent a highly promising new modality for tumor treatment. They offer advantages such as excellent safety, long-term expression, and sustained antigen presentation. Additionally, they can mimic the natural infection process of viruses to activate the immune system, eliciting robust immune responses against tumors. Currently, no mRNA therapeutic vaccines targeting HBV-related antigens have been approved for marketing. This HBV mRNA injection is an mRNA therapeutic vaccine encoding HBV-related specific antigens. Its active ingredient consists of modified mRNA encoding HBV-related antigen proteins, formulated into an injectable preparation via lipid nanoparticle (LNP) encapsulation. Preclinical safety evaluations have demonstrated that this vaccine exhibits low toxicity and good tolerability. Building on these preliminary results, this study aims to further evaluate its potential.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing HBV mRNA vaccine in people with Hepatocellular Carcinoma (HCC), run by West China 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 5 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: looking for participants now, as of the sponsor's last update on 22 Jul 2025. 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?

This study is still under way. Results are not available in the source record yet.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose-limiting toxicities (DLTs) and their incidence rates (time frame: During one year after initial treatment). The study lists 2 primary outcomes in all. 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 22 Jul 2025.
