About this study
Official title: A Phase I Clinical Study to Evaluate the Safety, Tolerability, and Preliminary Efficacy of an Artificial Intelligence-Designed Tumor mRNA Vaccine in Patients With Advanced or Metastatic Solid Tumors
This is a phase I, open-label, single-arm, single-center, dose-escalation study to evaluate the safety, tolerability, and preliminary anti-tumor efficacy of PAN-NeoVax, an artificial intelligence (AI)-designed pan-cancer neoantigen mRNA vaccine delivered via lipid nanoparticles (LNP), administered by intratumoral injection in patients with advanced or metastatic solid tumors who have failed second-line therapy. The study employs a classical "3+3" dose-escalation design with three dose levels (25 μg, 50 μg, and 100 μg mRNA). Each subject will receive 5 doses of basic immunization (first 4 doses at weekly intervals, fifth dose at 1 month after the fourth dose).

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing PAN-NeoVax (25 μg), PAN-NeoVax (50 μg) and PAN-NeoVax (100 μg) in people with Cancer, run by West China Hospital at 2 sites 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 15 inclusion and 12 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 11 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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?
Contact Xingchen Peng (18980606753, pxx2014@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants with DLT (time frame: From the first dose to 3 weeks post-dose.). 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 11 May 2026.
