Trial summary

Exploiting the immunostimulatory capacities of dendritic cells holds great promise for cancer immunotherapy. A mouse model for malignant mesothelioma allowed us to prove that autologous dendritic cells presenting tumor antigens were very effective by (partly) inhibiting tumor growth.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients with clinically and histological or cytological confirmed newly diagnosed mesothelioma, that can be measured in two dimensions by a radiologic imaging study.
  • Patients must be at least 18 years old and must be able to give written informed consent.
  • Patients must be ambulatory (Karnofsky scale > 70, or WHO-ECOG performance status 0,1, or 2) and in stable medical condition. The expected survival must be at least 4 months.
  • Patients must have normal organ function and adequate bone marrow reserve: absolute neutrophil count > 1.5*109/l, platelet count > 100*109/l, and Hb > 6.0 mmol/l.
  • Positive delayed type hypersensitivity skin test (induration > 2mm after 48hrs) against at least one positive control antigen of MULTITEST CMI (Pasteur merieux).
  • Stable disease or response after chemotherapy.
  • Availability of sufficient tumor material of the patient.
  • Ability to return to the Erasmus MC for adequate follow-up as required by this protocol.

Who cannot join

  • Conditions that make the patient unfit for chemotherapy or progressive disease after 4 cycles of chemotherapy.
  • Pleurodesis at the affected side before the pleural fluid is obtained.
  • Medical or psychological impediment to probable compliance with the protocol.
  • Patients on steroid (or other immunosuppressive agents) are excluded on the basis of potential immune suppression. Patients must have had 6 weeks of discontinuation and must stop of any such treatment during the time of the study.
  • No prior malignancy is allowed except for adequately treated basal cell or squamous cell skin cancer, superficial or in-situ cancer of the bladder or other cancer for which the patient has been disease-free for five years.
  • Serious concomitant disease, no active infections. Patients with a history of autoimmune disease or organ allografts, or with active acute or chronic infection, including HIV and viral hepatitis.
Show all 13Show fewer
  • Patients with serious intercurrent chronic or acute illness such as pulmonary (asthma or COPD) or cardiac (NYHA class III or IV) or hepatic disease or other illness considered by the study coordinators to constitute an unwarranted high risk for investigational DC treatment.
  • Patients with a known allergy to shell fish (contains KLH).
  • Pregnant or lactating women.
  • Patients with inadequate peripheral vein access to perform leukapheresis
  • Concomitant participation in another clinical trial
  • An organic brain syndrome or other significant psychiatric abnormality which would comprise the ability to give informed consent, and preclude participation in the full protocol and follow-up.
  • Absence of assurance of compliance with the protocol. Lack of availability for follow-up assessment.

About this study

Official title: Vaccination With Autologous Dendritic Cells Pulsed With Tumor Lysate for Treatment of Patients With Malignant Pleural Mesothelioma

Exploiting the immunostimulatory capacities of dendritic cells holds great promise for cancer immunotherapy. A mouse model for malignant mesothelioma allowed us to prove that autologous dendritic cells presenting tumor antigens were very effective by (partly) inhibiting tumor growth. This study will test the feasibility and safety of a clinical trial using autologous DC as a therapeutic adjuvant for the treatment of malignant pleural mesothelioma.

Read the detailed description

For this phase I study, patients with end-stage malignant mesothelioma and who are deemed to be fit enough to be treated with chemotherapy will be asked to participate in this study. Patients will first be treated with 4 courses of chemotherapy (standard treatment[Alimta/cisplatin]). After this chemotherapy a leukapherese is performed of which the monocytes are used for differentiation to dendritic cells. The procedure to grow these dendritic cells in vitro (culture) and pulse them with tumor lysate is performed in a cleanroom environment. Several quality control tests will be performed before the dendritic cells are ready for re-injection. Three doses of properly pulsed autologous dendritic cells are then re-injected every two weeks.

Using the proper procedure in mesothelioma patients, minor side effects are expected.

Ten (10) patients will be treated by this procedure to define the safety and toxicity of immunization and to observe (anti-tumor) immune responses.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing tumor lysate-loaded autologous dendritic cells in people with Malignant Pleural Mesothelioma, run by Erasmus 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 8 inclusion and 13 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 16 Nov 2010. 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 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 (time frame: april 2008). 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?

On the ClinicalTrials.gov record for NCT00280982, which also lists 2 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 16 Nov 2010; AzTrials last refreshed its copy on 3 Nov 2026.
