Trial summary

The goal of this laboratory research study is to identify possible differences in a gene among patients with breast cancer that cannot be treated by surgery. Researchers want to find out if differences in this gene may increase the risk of side effects from capecitabine. Read more about this study

About this study

Official title: A Retrospective Analysis of the Association of Dihydropyrimidine Dehydrogenase (DPYD) Variants With Toxicity Related to Capecitabine

The goal of this laboratory research study is to identify possible differences in a gene among patients with breast cancer that cannot be treated by surgery. Researchers want to find out if differences in this gene may increase the risk of side effects from capecitabine.

Read the detailed description

If you agree to take part in this study, 1 blood sample (about 2 tablespoons) will be drawn for use in genetic research.

If you are unable to provide a blood sample, researchers will collect leftover tissue samples from your previously collected tumor tissue (from the time of the breast cancer diagnosis). The tumor samples will be used for genetic research.

After the blood draw or tissue collection, your participation in this study will be over.

The blood samples for the genetic research will be stored at Myriad Laboratories. Before your blood and/or tissue is sent to Myriad Laboratories for banking, your name and any personal identifying information will be coded to protect your privacy. M. D. Anderson will not have oversight of any leftover tissue and/or blood that will be banked by Myriad Laboratories for additional research.

This is an investigational study. Up to 210 patients will take part in this study. All will be enrolled at M. D. Anderson.

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by M.D. Anderson Cancer Center at 1 site in United States.

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 2 inclusion and 1 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 8 May 2017. 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 United States. 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.

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?

Incidence of DPYD variants in patients (time frame: 2 Years). 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 8 May 2017.
