Transfected Dendritic Cell Based Therapy for Patients With Breast Cancer or Malignant Melanoma

August 18, 2015 updated by: Inge Marie Svane

Evaluation of Dendritic Cells Transfected With Survivin, hTERT and p53 mRNA as a Treatment for Patients With Metastatic Breast Cancer or Malignant Melanoma

The primary aim of this study is to evaluate the toxicity of the vaccine and the combination of the vaccine and Cyclophosphamide, and to evaluate the immune response induced by the vaccine. The secondary aim is to investigate the clinical tumour response and duration of tumour and immune response.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Phase I trial. Single center study; patients will be referred to the study center from other institutions in Denmark. 14 patients will be included in this phase I trial DC vaccination regime consists of primary 6 biweekly intradermal injections with transfected dendritic cells, followed by monthly injections until progression; Cyclophosphamide is used as vaccine adjuvant.

Defined procedures are employed for generation of autologous dendritic cells for clinical application in a classified laboratory. Unmobilized leukapheresis will be used for isolation of large-scale mononuclear cells, and dendritic cells will be generated from monocytes by cytokine stimulation and transfected with mRNA encoding for hTERT, survivin and p53 if the tumour express p53. Frozen preparations of dendritic cells will be prepared using automated cryopreservation. Each patient will receive a minimum of 1x106 dendritic cells per treatment supplemented with Cyclophosphamide 50 mg twice a day every second week. Toxicity including autoimmunity will be evaluated using the Common Toxicity Criteria (CTC).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
