About this study

This is a pilot study evaluating the use of tumor derived exosomes as a marker for response to therapy in women receiving neoadjuvant chemotherapy for newly diagnosed breast cancer. Tumor derived exosome analysis may be a novel diagnostic and prognostic biosignature in breast cancer, which could prove to be a tool for earlier diagnosis, more effective treatments, and improved markers of response in order to increase survival rates.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT01344109
Study groupRoleWhat they receive
Breast cancer patientsNewly diagnosed patients with breast cancer presenting with operable breast tumor prior to initiation of of neoadjuvant chemotherapy (choice of chemotherapy will be the the treating physician's discretion)
Healthy volunteersAdult women without a cancer diagnosis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To characterize protein surface markers and RNA profiles in tumor derived exosomes from breast cancer patients undergoing neoadjuvant chemotherapy

    Compare tumor derived exosomes at baseline, monthly during chemotherapy, at the completion of chemotherapy treatment, and after surgery to determine residual cancer burden. Tumor derived exosome expression will be correlated with both clinical and pathologic response.

    Measured: up to 2 years from start of study

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Neoplasms, run by Leo W. Jenkins 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 8 inclusion and 5 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The record says: withdrawn, as of the sponsor's last update on 21 Jul 2017.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 was withdrawn before enrolling participants, so there are no results.

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 characterize protein surface markers and RNA profiles in tumor derived exosomes from breast cancer patients undergoing neoadjuvant chemotherapy (time frame: up to 2 years from start of study). 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 21 Jul 2017.
