Metastatic Breast CancerPhase 2NCT00212069
Serum Proteomics to Predict Gemcitabine Sensitivity in Breast Cancer
A Phase 2 study testing gemcitabine, carboplatin in people with Metastatic Breast Cancer, run by National University Hospital, Singapore at 1 site in Singapore.
Trial summary
Tumors are heterogeneous with varying response to chemotherapeutic agents. We hypothesize that tumors that are sensitive to a particular chemotherapeutic agent have a distinctive tumor protein profile compared to those that are resistant. Read more about this study

About this study
Official title: Serum Protein Profiling as a Predictor of Gemcitabine Sensitivity in Breast Cancer With Prior Exposure to Anthracyclines and Taxanes
Tumors are heterogeneous with varying response to chemotherapeutic agents. We hypothesize that tumors that are sensitive to a particular chemotherapeutic agent have a distinctive tumor protein profile compared to those that are resistant. We further hypothesize that since tumor is continuously perfused by serum, serum protein profile can be used as a surrogate marker of tumor protein profile. The primary objective of this study is to identify a serum protein profile that predicts gemcitabine/carboplatin sensitivity or resistance in breast cancer patients with prior exposure to anthracyclines and taxanes. Secondary objectives are to establish the serum protein profile of breast cancer patients who have had prior exposure to anthracyclines and taxanes, and to study the pharmacogenetics of gemcitabine toxicity by correlating germline genotype of transporters and drug metabolizing enzymes with plasma and intracellular gemcitabine pharmacokinetics.
Read the detailed description
Metastatic breast cancer patients previously treated with anthracyclines and taxanes will be treated with gemcitabine and carboplatin every 3 weeks. Serial plasma samples will be collected for proteomics profiling with SELDI-MS that will be correlated with tumor response to identify biomarkers that may predict for chemotherapy sensitivity.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing gemcitabine, carboplatin in people with Metastatic Breast Cancer, run by National University Hospital, Singapore at 1 site in Singapore.
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 13 inclusion and 8 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 11 Dec 2013. 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 Singapore. 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 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?
To identify a serum protein profile that predicts gemcitabine/carboplatin sensitivity or resistance in breast cancer patients with prior exposure to anthracyclines and taxanes.. 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 11 Dec 2013.
