Trial summary

Tumor-specific antigens can be induced by demethylation drugs. Antigen-targeting DC-CTL cells supposed to eliminate cancer cells efficiently and specifically.

About this study

Tumor-specific antigens can be induced by demethylation drugs. Antigen-targeting DC-CTL cells supposed to eliminate cancer cells efficiently and specifically. In this study investigators co-culture DCs cells with peptides derived from tumor specific antigen to generate antigen-specific DC-CTLs (Ag-CTL). Following treatment with demethylation drugs, Ag-CTL will be used to eliminate tumor cells. This study aims to evaluate the effectiveness and safety of Ag-CTL combined with demethylation drugs.

Read the detailed description

A large number of studies have confirmed that demethylated drug decitabine can effectively induce tumor-specific antigen expression. Tumor-specific antigens have strong specificity and are ideal therapeutic targets. In this study, tumor-specific antigens were used as therapeutic targets. The researchers screened the tumor-specific epitope peptides through bioinformatics database combined with in vitro experiments. The peptide-loaded DCs are co-cultured with T lymphocytes to induce the proliferation of CTLs, which are then refusion to tumor patients to treating diseases.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing DC-CTL in people with Malignant Tumor, run by Shenzhen University 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 7 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: status not confirmed, as of the sponsor's last update on 17 Dec 2020. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Shujiao He, Dr (0755-21838178, he_shujiao@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

PFS (time frame: From date of initial treatment until the date of first documented progression, assessed up to 36 months.). 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 17 Dec 2020.
