Plain English Summary
Background and study aims
Breast cancer is the most common cancer in women. The goal of our research is the diagnosis and monitoring of patients after treatment, to improve the detection of tumours coming back or spreading to other parts of the body. We want to evaluate the safety and the functionality of a medical device which is able to detect cancer cells in the bloodstream. A thin catheter, also called a nanodetector, is inserted into an arm vein. The nanodetector has a special coating which has the ability to bind cancer cells and thus to estimate the number of circulating tumour cells. This method has the advantage of fishing for tumour cells in a much larger volume than a standard blood sample taken out of the body.
Who can participate?
Female participants aged 18 years or older who have breast cancer and have not had surgery yet.
What does the study involve?
If you take part in the study, first of all, you will be asked to give a small sample of blood. Should you be eligible to participate the nanodetector will be inserted into an arm vein. The procedure of the insertion of the nanodetector is similar to inserting a small tube for blood collection and takes 30 minutes. This is a standard procedure in hospitals and medical practices. All patients in the study will be treated in the same way. Afterward you will be asked again to give a small sample of blood to check if blood values change after the insertion of the nanodetector.
What are the possible benefits and risks of participants?
The procedure is similar to normal blood collection, therefore the risk for the participants is comparable to the risk of a normal blood collection. All insertions of the nanodetector will be carried out by trained physicians.
Where is the study run from?
Wilelkopolskie Cancer Centre, Poznan, Poland.
When is the study starting how long is the expected to run for?
Patients have been enrolled since May 2011, and the study will end in September 2012
Who is funding the study?
GILUPI, Potsdam, Germany.

In vivo isolation of circulating tumor cells from peripheral blood of patients with breast cancer by using a structured antibody-coated nanodetector: an explorative mono-centre non-randomised trial
The aim of this explorative mono-centre trial is the in vivo proof of concept. The compatibility in patients with operable breast cancer after exposure of the nanodetector in the patient vein for 30 minutes will be tested. Besides of that a performance analysis will be carried out. In a second group of patients with operable breast cancer a double application of the nanodetector will be performed to assess the reliability of the nanodetector after positive evaluation of the proof of concept. In parallel the antibody-based CellSearch® assay will take place to compare the in vivo isolation with the nanodetector with the FDA-approved CellSearch® method.
On 26/04/2013 the anticipated end date was changed from 30/09/2012 to 31/12/2013.
On 15/05/2013 the target number of participants was changed from 82 to 78. This correction was made due to an error in the original application.

Breast cancer (stage I-IV)
The first group of patients will receive a single application of the nanodetector. After the complete recruitment of this group of patients a second group will be included in the study. In the second group of participants two nanodetectors will be applied under the same conditions. The nanodetector will be inserted pre-operatively. Each nanodetector will be inserted in an arm vein for 30 min. To demonstrate the functionality of the nanodetector circulating tumor cells will be detected by immunocytochemistry. In parallel, a blood sample will be taken from every patient before the application of the nanodetector. This blood sample will be analyzed with the CellSearch® method. At the end the data from these two methods will be compared.
Primary outcome measure
1. Positive isolation of circulating tumor cells from the peripheral blood of patients with breast cancer by using the nanodetector (proof of concept)
2. Demonstration of good biocompatibility
Secondary outcome measures
1. Assessment of the accuracy of the nanodetector
2. Review of product application procedures
3. Comparision of the results with the CellSearch® method
