ISRCTN - ISRCTN55277999: In vivo isolation of circulating tumor cells from peripheral blood of patients with lung cancer by using a structured antibody-coated nanodetector

Plain English Summary

Background and aims
Lung cancer is the most prevalent cancer and the major cause of cancer-related death worldwide. To detect this kind of cancer in very early stages, modern radiological diagnostic methods are used. An important part is the monitoring of the patients after cancer treatment, and to predict the outcome of the disease, especially the early detection of local recurrence (cancer coming back) and distant metastases (spread of cancer to other parts of body). The goal of our research is the identification of the disease and monitoring of patients after treatment.
We want to evaluate with this study the safety and the functionality of a medical device, which is able to isolate circulating cancer cells from the bloodstream. A thin wire, also called nanodetector, is inserted into the bloodstream. The nanodetector has a special coating which has the ability to bind to cancer cells and thus to estimate the number of circulating tumor cells. This method has the advantage of identifying tumor cells in a much larger volume than a standard blood sample taken out of the body.

Who can participate?
You are 18 years or older with lung cancer and you have not undergone 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 to test blood values for inclusion and exclusion into the study. Should you be eligible to participate the nanodetector will be inserted in the vein. The procedure of inserting the nanodetector is similar to inserting a small tube for blood collection and takes 30 min. This is a standard procedure in hospitals and medical practices. All patients in the study were treated in the same way. Afterwards 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 participating?
The cancer patients participating benefit from increased regular medical care, ranging from the provision of additional, non-routine blood tests.
The procedure is similar to a 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?
The study takes place at the Medical University in Poznan, Clinic for Thoracic Surgery, Poland

When is study starting and how long is it expected to run for?
Patients have been enrolled since March 2010, and the study will end in March 2012. Until that time 60 subjects should be enrolled.

Who is funding the study?
The study is being funded by the GILUPI company (Potsdam, Germany)

Scientific title

In vivo isolation of circulating tumor cells from peripheral blood of patients with lung cancer by using a structured antibody-coated nanodetector: An explorative mono-center non-randomized blinded trial

Acronym

Study hypothesis

The aim of this explorative mono-centre trial is the in vivo proof of concept. The compatibility in patients with operable lung cancer after exposure of the nanodetector in the patient vein for 30 minutes will be tested. Besides of that a performance analysis will be done. In a second group of patients with operable lung 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. The specificity of the device will be tested by the inclusion of a control group (non-cancer patients). The analysis of the applied nanodetectors will be done under blinded conditions. In parallel the CellSearch system, using a similar antibody-based extraction technique for circulating tumor cells in a single blood sample in vitro, will be used as a reference system. Furthermore the CEER-Assay (Prometheus Labs) will be used for an explorative analysis of certain tumor relevant protein pathways on the isolated CTCs.

Condition

Lung cancer (non small cell lung cancer - NSCLC, stage I-IV)

Intervention

The first group of participants will receive a single application of the nanodetector. This set of subjects is the blinded part of the study. Non-cancer and lung cancer patients will be included in the study. After the complete recruitment of this group of subjects a second group (only cancer patients) will be included in the study.

In the second group of participants two nanodetectors will be applied under 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. The CellSearch® method (method with FDA-approval) acts as a reference system. At the end the data from these two methods will be compared.
