A Early Phase 1 study testing laboratory biomarker analysis, adjuvant therapy and radiation therapy in people with Breast Cancer, run by University of California, San Francisco at 1 site in United States.
Trial summary
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy in different ways may kill more tumor cells.

About this study
Official title: The Relationship Between Plasma Transforming Growth Factor-beta 1 (TGF-β) and Fractionation in Radiotherapy for Breast Cancer: A Randomized Study
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy in different ways may kill more tumor cells.
PURPOSE: This randomized clinical trial is studying the side effects and best way to give radiation therapy and to see how well it works in treating patients with invasive breast cancer.
Read the detailed description
OBJECTIVES:
Primary
- Compare the ratio between post- and pre-treatment plasma transforming growth factor-beta 1 (TGF-β) in women with invasive breast cancer undergoing hypofractionated radiotherapy vs standard-fractionated external-beam radiotherapy.
Secondary
- Establish longitudinal serum and plasma biorepository for retrospective evaluation of TGF-β and other biomarkers with special relevance to radiation response.
- Correlate pre-treatment plasma TGF-β levels with clinical fibrosis development.
OUTLINE: This is a randomized study. Patients are randomized to 1 of 2 treatment arms.
- Arm I (hypofractionated radiotherapy): Patients undergo external-beam radiotherapy once daily 5 days a week for up to 3.5 weeks (16 fractions total).
- Arm II (standard fractionated radiotherapy): Patients undergo radiotherapy as in arm I at a lower dose for up to 5 weeks (25 fractions total).
After completion of study treatment, patients are followed every 6 months for 2 years and then annually for 3 years.
PROJECTED ACCRUAL: A total of 100 patients will be accrued for this study.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing laboratory biomarker analysis, adjuvant therapy and radiation therapy in people with Breast Cancer, run by University of California, San Francisco 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?
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 21 Aug 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 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.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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.
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 21 Aug 2013.
