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 17th World Conference on Lung Cancer
GILUPI will participate at the 17th World Conference on Lung Cancer (WCLC) in Vienna, Austria. The WCLC is the world’s largest meeting dedicated to lung cancer and other thoracic malignancies. The meeting will take place from 4th to 7th December with more than 7.000 participants expected.
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. Dr. Julia Herrmann, clinician at the SRH Wald-Klinikum Gera - a certified lung cancer center (DKG), will present first data from a clinical trial using the GILUPI CellCollector®, to monitor CTC counts before and after surgery in non-small cell lung cancer (NSCLC) patients. The CTCs were further characterized on a molecular level. First results from 20 patients show that CTCs were isolated independent from tumor stages and could even be detected in quite early cases. Moreover, the difference between CTC occurrence before and after surgery suggested the possibility to identify patients responding to therapy or patients with stable disease.
The poster presentation will take place on Monday the 5th December in Hall B between 2.30 pm and 3.45 pm (abstract ID 5975). You are invited to meet Dr. Julia Herrmann as well as Dr. Jens Pfannkuche (CEO, GILUPI GmbH) and Dr. Julia Schulz (GILUPI, R&D division), which will also participate at this poster session.
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).
Identification and enumeration of Circulating tumor cells in neuroendocrine tumor patients with GILUPI CellCollector®
GILUPI GmbH announces, that in August 2016 a published scientific paper demonstrated for the first time circulating tumor cell (CTCs) isolation in neuroendocrine tumor patients with GILUPI CellCollector®.
Isolating and analyzing circulating tumor cells as a “liquid biopsy” can be an additional source of diagnosis, prognosis, evaluation of treatment efficacy and molecular tumor evolution and metastatic sites. CTCs have been, so far, identified in patients with metastatic neuroendocrine tumor (NET) using a comparator method with limited sampling volume that leads to the detection of low frequency CTC numbers. Professor Tim Meyer and his group from the UCL Cancer Institute, University College London wanted to overcome this limitation and increases CTCs numbers by using the GILUPI CellCollector®.
In their study, the researcher used the GILUPI CellCollector® and the comparator method. In total, 34 patients with metastatic NET were enrolled and the GILUPI CellCollector® was used to isolate CTCs in vivo.
Applying the GILUPI CellCollector® in 33 of 34 NET patients CTCs were found with a median of 6 CTCs. In comparison, in only 16 of 34 NET patients with a median of 0 CTC could be detected with the comparator method. More importantly, the researcher investigated the prognostic relevance of CTC count with GILUPI CellCollector®. Using a cut-off of 7 CTCs, the progression free survival of patients with less than or equal 7 CTCs was in median 11 months compared to patients with more than 7 CTCs had a significantly lower progression free survival. Further studies are needed to validate this finding to potentially aid the treatment of patients with neuroendocrine tumors.
The scientific paper entitled "A comparison of CellCollector with CellSearch in patients with neuroendocrine tumors by Mandair et al., was published in Endocrine-Related Cancer, pii: ERC-16-0201. PMID:27521132 (12th August 2016).

GILUPI ist Partner im europäischen Konsortium „CANCER-ID“ zur Validierung Blut-basierter Krebs-Biomarker
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.
