About this study
Official title: Phase 1 Study: Induction of Systemic Immune Responses in Metastatic Breast Cancer Patients by Vaccination With a CD80-modified, Devitalized HLA-*A0201+ Breast Cancer Cell Line (KS24.22)
In the last few years there has been a great attempt to develop active immunotherapies for breast cancer patients (BCPs) using undefined as well as selected antigens to activate tumor specific T-lymphocytes. The purpose of this phase-I study was to determine the safety and feasibility of vaccinations with an allogeneic breast cancer cell line, KS24.22, genetically modified to express CD80 and Her-2/neu, and to evaluate the efficacy of inducing tumor antigen-specific immune responses in human leukocyte antigen(HLA)-A*02-matched patients with metastatic breast cancer.
Read the detailed description
The trial was designed as an open label phase-I. Informed consent was given twice by the patients (1st for HLA-typing, 2nd for participation in the vaccination trial).
The first four vaccinations, which were given every two weeks, were followed by four monthly vaccinations. Additional vaccinations were permitted on request for patients who exhibited stable disease (SD).
Immediately before administration, KS24.22 cells were thawed and lethally irradiated. KS24.22 cells were adjusted to 10E7/ml in Ringer-Lactate-solution, transferred to 1 ml syringes and stored on ice until injected within a time frame of 2h. Vaccinations were given i.d. in the thigh with a total volume of 1 ml divided between two injection sites.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing KS24.22 cells in people with Metastatic Breast Cancer, run by University Hospital Tuebingen at 1 site in Germany.
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 7 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 20 May 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 Germany. 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 of KS24.22 administration (time frame: 2 years). 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 NCT01127074, which also lists 1 linked publication.
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 20 May 2010.
