Quantification and phenotyping of circulating tumor cells isolated with the GILUPI CellCollector® technology
GILUPI announces the release of a video article presenting an innovative approach for isolation of circulating tumor cells (CTCs) by the use of the GILUPI CellCollector® and their downstream phenotyping in combination with chromosomal rearrangement detection .
CTCs can often be found in the blood of cancer patients. They are a promising surrogate marker for disease progression and response to therapy. CTCs indicate tumor cell extravasation and are prerequisites for formation of metastasis. Detection and characterization of these rare cells could provide a powerful approach for early disease diagnosis as well as disease monitoring. The GILUPI CellCollector® offers medical personnel at any point-of-care with the unique opportunity to enrich these CTCs in vivo.
Fabbri and colleagues from Cancer Institute IRST of Meldola in Italy presented a method which combines immunofluorescence staining and DNA FISH analysis of in vivo isolated CTCs. They demonstrated the feasibility of this new approach by determination of tumor relevant markers (EpCAM expression and ALK chromosomal translocations) in a lung cancer cell line attached on the medical wire of GILUPI. This new concept will enhance prognostic value of CTCs and provides an innovative strategy for improving personalized cancer treatments.

New study extends application range of GILUPI CellCollector® towards quantitative analysis of gene expression in circulating tumor cells
GILUPI announces the publication of a peer reviewed study about a new and promising mRNA-based assay that allows detection and quantification of clinically relevant prostate and pancreas cancer markers in circulating tumor cells (CTCs).
CTCs are a surrogate marker for cancer progression and response to therapy. CTCs indicate tumor cell spreading and are a prerequisite for the development of metastasis. Detection and characterization of these rare cells could provide a powerful approach for early disease diagnosis as well as disease monitoring. The GILUPI CellCollector® offers medical personnel at any point-of-care with the unique opportunity to enrich these CTCs in vivo.
In this peer reviewed study, El-Heliebi from the Medical University of Graz and his coworkers combine the enumeration and expression analysis of CTCs by developing an in situ padlock probe assay. This method enables the quantitative analysis of mRNA expression for therapy relevant cancer markers. For this study, the GILUPI CellCollector® was applied to patients with prostate and pancreatic cancer and subsequent CTC enumeration and detection of mRNA transcripts were conducted by fluorescence microscopy.
In summary, CTCs were detected in 62% of prostate cancer and 47% of pancreatic cancer patients and therapy relevant cancer markers (e.g. AR-V7 transcripts or KRAS mutations) were identified in the majority of those cells.
This advanced approach will improve the predictive and prognostic value of CTC analysis in clinical practice and therefore lead to further advances in cancer research and patient care.

Molecular characterization of Circulating Tumor Cells isolated with GILUPI technology from prostate cancer patients – A new promising diagnostic approach
GILUPI GmbH announces the recent publication of a clinical study demonstrating multiplex gene expression profiling of circulating tumor cells (CTCs) isolated in vivo from high-risk prostate cancer patients by the use of GILUPI CellCollector® .
Prostate cancer is a very common cancer and accounts for one of the most related cancer deaths among men. About 15%-30% of patients with prostate cancer are diagnosed with high-risk disease, often treated with local therapy. Nevertheless, the incidence of a relapse or a metastatic disease stresses the need for optimizing the treatment. The researcher Markou and colleagues from the University of Athens in Greece investigated, if combination of in vivo CTC isolation with downstream RNA analysis can be a useful tool to optimize individual treatment of high-risk prostate cancer patients. Therefore, EpCAM-positive CTCs were isolated in vivo using the GILUPI CellCollector® from 105 high-risk prostate cancer patients. Additionally, a group of 36 healthy volunteers were enrolled as noncancerous controls. For molecular characterization of CTCs the researcher developed a multiplex RT-qPCR assay for 14 genes, including epithelial markers, stem cell markers and epithelial-to-mesenchymal-transition (EMT) markers.
For the first time, a publication of a clinical study presented RNA analysis of in vivo isolated CTCs in cancer patients. They observed a high heterogeneity in gene expression in the captured CTCs for each patient. The expression of at least one marker was detected in the vast majority of enrolled prostate cancer patients (70.5%), but not in healthy individuals. Moreover, at least 2 markers were positive in 45 of 105 patients (40.9%), and 3 markers in 16 of 105 patients (15.2%). More importantly, they observed a change of marker expression before and after treatment. In conclusion, combining in vivo isolation of CTCs using GILUPI CellCollector® with downstream RT-qPCR assay is a minimal-invasive, highly specific and sensitive approach for molecular diagnostics in cancer patients.

Early lung cancer screening with CTC detection using the GILUPI CellCollector® and Low-Dose Computed Tomography
GILUPI GmbH announces the release of a scientific article about the detection of circulating tumor cells (CTCs) from blood of different groups of pulmonary disease patients by the use of GILUPI CellCollector® .
Lung cancer is worldwide the most common cause of cancer-related death in men with a five-year survival rate lower than 20%. Two of three lung cancer patients have an advanced stage disease at initial diagnosis. Cancer mortality might be reduced dramatically, when the disease and its metastatic spread are detected and characterized early on and consequently treated in an optimal fashion. Yutong He and colleagues from the Fourth Hospital of Hebei Medical University in China investigated if combining to methods – Low-Dose Computed Tomography (LDCT) and enumeration of CTCs using the GILUPI CellCollector® - improves early detection of lung cancer. To explore the effectiveness of combined methods, 8313 volunteers were screened by LDCT: 32 ground-glass nodules (GGNs) and 19 healthy volunteers were randomly selected. Additionally, 15 lung cancer patients were enrolled. In the selected cohorts, CTCs were detected with the GILUPI CellCollector®.
In this study, about 73% of the lung cancer patients were detected as CTC positive. Detection rate of CTCs in GGN patients, a cohort that has a 5 to 10% risk to develop lung cancer in future, was lower (16%) when compared to the lung cancer group, but higher than in the healthy control group, where not CTCs were detected. Moreover, all CTCs isolated from GGN patient were analyzed with next-generation sequencing (NGS), finding mutations in three cancer-related genes (KIT, SMARCB1 and TP53 genes). In conclusion, the clinicians showed that combining LDCT with CTC analysis using the GILUPI CellCollector® is a promising way to screen for early-stage lung cancer.

GILUPI will attend at the ACTC congress in Rhodes
GILUPI GmbH is pleased to announce its participation at the 2017 ACTC (Advances in Circulating Tumor Cells) congress.
The 3rd ACTC meeting will take place from 4th to 7th October in Rhodes, Greece and is focused on “Liquid Biopsy in clinical practice”. This congress brings together researchers, clinicians and companies, to discuss practical implementation of CTCs (circulating tumor cells) and ctDNA (circulating tumor DNA) and translate much of the excellent basic research in this field into clinical practice.
GILUPI will use this opportunity to present interim data from a clinical trial at the SRH Wald-Klinikum Gera - a certified lung cancer center in Germany. The clinical investors Dr. med. habil. Thomas Lesser and Dr. med. Julia Herrmann using the GILUPI CellCollector®, to monitor CTC counts before and after surgery in non-small cell lung cancer (NSCLC) patients. First results from 20 patients show that CTCs were isolated independent from cancer grade and could even be detected in quite early tumor stages. The difference between CTC occurrence before and after surgery suggested the possibility to identify patients responding to therapy or patients with stable disease. Moreover, a correlation between CTC numbers and clinical lack of recurrence was observed. In addition, patients were tested positive for PDL1 (Programmed death-ligand 1 / CD274) expression in CTCs.
The poster presentation will take place on Thursday 5th of October at 3.30 pm - 4.30 pm. You are invited to meet Dr. Johanna Schiller from the GILUPI R&D department.
In vivo detection of CTCs in head and neck cancer patients using the GILUPI CellCollector®
GILUPI GmbH announces the recent publication of a clinical study demonstrates the isolation of circulating tumor cells (CTCs) from blood of squamous cell carcinoma of head and neck (SCCHN) patients with the GILUPI CellCollector® .
Isolating and analyzing CTCs from the blood of cancer patients can provide additional information on prognosis, course of disease, treatment efficacy and molecular tumor evolution. CTC detection is challenging due to their extremely low frequency amongst millions of leucocytes and billions of red blood cells. Especially in SCCHN, the sensitivity of CTC isolation with conventional in vitro methods is low and insufficient to satisfy clinical requirement. Zhang and further colleagues from the Nanjing Tongren Hospital in China wanted to overcome this limitation by using the in vivo GILUPI CellCollector® technology. Therefore, from November 2016 to April 2017 the clinicians enrolled 22 newly diagnosed SCCHN patients as well as 9 healthy volunteers.
Published data are already available for CTC isolation using the GILUPI CellCollector® technology in patients with prostate cancer, neuroendocrine tumors, metastatic breast and lung cancer with high positivity rates (54 – 97%). In addition, this Chinese study revealed for the first time, a high incidence of CTCs in patients with squamous cell carcinoma of head and neck. In total, 72.7% (16/22) were positive for ≥ 1 CTC (range 1-17 cells). The CTC detection rate was higher in patients with late stages than in patients with early stages. More importantly, CTC number changes as a marker for analyzing surgical response was tested. Zhang et al. showed that positivity rate decreases from 72.7% with median CTC number of 2 before surgical treatment to 46.7% with median CTC number of 0 after surgical treatment. Moreover, the expression of a therapy relevant oncogene (EGFRVIII) was detected on CTCs and this positive expression was also found in both primary and metastatic tumor tissue. These data revealed that an in vivo detection of CTCs had high sensitivity in SCCHN, which might improve CTC application in clinic.

Improved detection of circulating tumor cells in prostate cancer patients using the GILUPI CellCollector® in combination with two blood-based assays
GILUPI GmbH announces the release of clinical data from a prostate cancer clinical study in December 2016. The scientific paper demonstrates the isolation of circulating tumor cells (CTCs) from blood of non-metastatic high-risk prostate cancer patients with the GILUPI CellCollector® .
Liquid biopsy - isolating and analyzing circulating tumor cells (CTCs) from the blood of prostate cancer patients - can provide additional information on prognosis of patients, treatment efficacy and molecular tumor evolution. Prof. Klaus Pantel, Dr. Kuske and further researchers from the department of tumor biology at the University Medical Center Hamburg-Eppendorf investigated the prognostic relevance of CTCs in non-mestastatic prostate cancer. The goal of this study was to increase the sensitivity of CTC detection in patients with high-risk prostate cancer through the combination of three complementary assays. For this purpose the unique and innovative GILUPI CellCollector® in vivo technology was included in this study.
Peripheral blood was analyzed directly before and 3 month after radical prostatectomy to assess early dynamics in CTC counts. In total, 86 and 52 patients were enrolled before radical prostatectomy and 3 month after surgery, respectively.
In this clinical trial, combined application of the different CTC detection technologies revealed for the first time, a high incidence of CTCs in non-metastatic high-risk prostate cancer patients. Moreover, the researcher showed that the usual restriction of analyzing large blood volumes from cancer patients could be circumvented by GILUPI CellCollector® application, which resulted in equal or higher incidences CTC detection as comparator systems. More importantly, CTC rates detected by the GILUPI CellCollector® displayed a statistically significant decrease after surgery (66% to 34%, p = 0.031). These data revealed that after radical prostatectomy a reduced number of EpCAM-positive CTCs circulate in the blood stream, which is likely owed to the fact that the primary tumor as a major source of CTCs had been removed.

GILUPI at the 6th Herbsttreffen AG Molekularpathologie
At the 6th Herbsttreffen AG Molekularpathologie in Karlsruhe, Germany, from 21th to 22th November 2016, GILUPI will be one of the exhibitors and sponsors of the event. The medical device company will be presenting its current product, the GILUPI CellCollector®, to an interested audience.
Liquid biopsy - isolating and analyzing circulating tumor cells (CTCs) from the blood of cancer patients - can provide additional information on prognosis of patients, treatment efficacy, resistance and molecular tumor evolution. Whereas CTCs represent the liquid phase of current tumor progression, cell free tumor DNA is apoptotic/necrotic cell material representing past cell death. CTC detection is challenging due to their extremely low frequency amongst millions of leucocytes and billions of red blood cells. The advanced GILUPI technology allows for the detection and characterization of CTCs combined with the proof of the malignant origin of the cells. The tumor cells are captured in vivo with high sensitivity and selectivity providing compelling and improved diagnostic use for personalized medicine, early diagnostic and clinical monitoring.
You are invited to visit our exhibition booth at the 6th Herbsttreffen AG Molekularpathologie. For further information on this congress, see here

Enumeration and molecular characterization of circulating tumor cells in prostate cancer patients using the GILUPI CellCollector®
GILUPI GmbH announces the release of clinical data from a prostate cancer setting in August 2016. The scientific paper demonstrate the isolation of circulating tumor cells (CTCs) from blood of prostate cancer patients with GILUPI CellCollector®.
Liquid biopsy - isolating and analyzing circulating tumor cells (CTCs) from the blood of prostate cancer patients - can provide additional information on prognosis of patients, treatment efficacy and molecular tumor evolution. Dr. Gerit Theil and further researcher from the Martin Luther University Halle-Wittenberg wanted to investigate the use of the GILUPI CellCollector® - in a proof of concept study. After in vivo isolation, CTCs underwent enumeration and characterization using molecular methods.
The researcher tested the functionality of the GILUPI CellCollector® in a preclinical step. They studied blood samples of 43 prostate cancer patients by applying the medical devices ex vivo.
Detection of CTCs in all tumor stages could be shown. The mean CTC count was 4.6 CTCs in patients with localized prostate cancer, 16.8 CTCs in patients with locally advanced prostate cancer, and 26.8 CTCs in patients with metastatic prostate cancer. More importantly, it could be shown that there was a significant difference in the cancer-specific survival rates. Patients with CTC counts < 5 CTCs had significant longer survival rates than patients with more than 5 CTCs. Furthermore, Theil et al. demonstrated that the captured CTCs could be characterized on a molecular level. The investigators detected tumor-associated transcripts of epidermal growth factor receptor (EGFR) and prostate-specific membrane antigen (PSMA) in patients with metastatic PCa in 42.8% and 14.3% of the analyzed samples, respectively. The above data was generated to demonstrate to the Federal Institute for Drugs and Medical devices (Germany, BfArM) the safe and effective use prior to in vivo application of the GILUPI CellCollector® in this indication. Further studies are ongoing to validate this finding as further diagnostic tool in the treatment of patients with prostate tumors.
The scientific paper entitled "The Use of a New CellCollector to Isolate Circulating Tumor Cells from the Blood of Patients with Different Stages of Prostate Cancer and Clinical Outcomes - A Proof-of-Concept Study.” by Theil et al., was published in PLoS One., 11(8):e0158354. doi: 10.1371/journal.pone.0158354. eCollection 2016. (1th August 2016).

He succeeds Klaus Lücke, who is leaving GILUPI after more than 10 years to move on to new professional challenges. Having a master degree in Business Administration, Alexander Herrmann (43) counts many years of experience in leadership at biotechnology companies. He is supposed to speed-up the GILUPI CellCollector® marketing as well as the necessary restructuring of the company.
Mr. Herrmann commented: “The GILUPI CellCollector® is a unique and innovative product. Our target for the coming months is to enhance the GILUPI CellCollector® application by adding further molecular analytical tools, thus making the application even more valuable for our customers. Moreover, we will upscale our production capacity in Greifswald and complement our team by additional experts.
GILUPI participates in European consortium „CANCER-ID“ to validate blood-based biomarkers for cancer
Blood-based biomarkers such as circulating tumor cells (CTCs), circulating free tumor DNA (cfDNA) and microRNAs (miRNAs) are established indicators of tumor burden in cancer patients. Assessment of these markers from blood provides an invaluable tool for modern cancer therapy.
In addition to being of high importance when biopsies of the original tumor are not accessible, blood-based liquid biopsy tests allow for close follow-up of disease markers to monitor treatment efficacy and potentially improve the choice of treatment options.
CANCER-ID is a newly formed European consortium funded by the Innovative Medicines Initiative (IMI) comprised of 33 partners from 13 countries focused on establishment of standard protocols and clinical validation of blood-based biomarkers (EGFR and HER2) in NSCLC and HER2-therapy resistant metastatic breast cancer.
The consortium brings together experts from academic and clinical research, innovative Small-to-Medium sized Enterprises (SMEs), diagnostics companies and the pharmaceutical industry - thus providing a unique setting for expanding the clinical utility of liquid biopsies. The project is supported by a substantial budget of EUR 14.5 million provided by industry partners (8.2 million EUR) as well as the IMI Joint Undertaking (EUR 6.3 million).
The academic leads of the CANCER-ID consortium are Prof. Klaus Pantel, Head of the Department of Tumor Biology at the University Medical Center Hamburg-Eppendorf, Germany, and Prof. Leon Terstappen, Head of the Department of Medical Cell Biophysics at the University of Twente, The Netherlands. Both are leaders in the field and have an impressive track record in basic research and applied science including device development. The EFPIA lead companies of the CANCER-ID consortium are Bayer HealthCare and Silicon Biosystems, a Menarini Group Company.
Klaus Luecke, founder of GILUPI commented: “This project is a major step for GILUPI, as it will demonstrate the superior performance of GILUPI technology in the isolation of CTCs for testing and monitoring of cancer patients. The isolation and subsequent characterization of blood-based biomarkers will become increasingly important as a method to monitor disease progression and therapy response. We believe that the liquid biopsy approach - with less-invasive and more frequent testing - will soon become part of the clinical routine for the benefit of a wide range of cancer patients.
