Trial summary

Dendritic cells (DCs)are the most potent antigen-presenting cells of the immune system, as such they are able to direct the immune system specifically against cancer cells. Currently DCs are used in clinical vaccination studies and immunological and clinical responses have been observed. Read more about this study

About this study

Official title: In Vivo Responses of DC Vaccines Presenting HLA Class I and II Restricted Tumor Epitopes Either by Peptide-pulsing or mRNA Transfection in Melanoma Patients

Dendritic cells (DCs)are the most potent antigen-presenting cells of the immune system, as such they are able to direct the immune system specifically against cancer cells. Currently DCs are used in clinical vaccination studies and immunological and clinical responses have been observed. For inducing anti-tumor immunity, the DCs have to be loaded with tumor antigen (i.e. molecular structures that are presented by the tumor, that are recognized by the immune system). Currently most studies use tumor peptides (small protein fragments) for this purpose. This approach has several disadvantages: only patients with a certain HLA-type can be treated and the immune response that is induced by the vaccine is limited to the used peptides. These disadvantages do not exist when the DCs present antigen which is endogenously processed, for example after RNA transfection. For this reason we investigate the immunogenicity of DCs that are pulsed with peptides or transfected with mRNA encoding melanoma associated antigens in stage III and IV melanoma patients.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing autologous dendritic cell vaccine in people with Melanoma Stage III or IV, run by Radboud University Medical Center at 1 site in Netherlands.

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 12 inclusion and 11 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 29 Sep 2009. 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 Netherlands. 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?

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?

Immune response (time frame: first 10 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00243529, which also lists 7 linked publications.

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 29 Sep 2009.
