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® [1]. 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.

The approval procedure, including the associated clinical study for the GILUPI CellCollector® has already been started in China. The GILUPI CellCollector® isolates complete circulating tumor cells (CTC) - the so-called liquid biopsy. To ensure a stable future and sustainable growth prospects within international markets, VIROAD now takes over all company shares. The investors, who accompany GILUPI financially and commercially since 2006, are pleased with the attractive exit. The HTGF, that allowed the launch of GILUPI as seed investor, emphasizes that "even the facility in Germany will strengthen and expand by the Chinese involvement. VIROAD will market the products in China, but needs the German site for developments and also to address the European markets.” said Dr. Michael Brandkamp, CEO of HTGF.

The managing director at GILUPI, Dr. Jens Pfannkuche, is convinced that the company can market its promising technology and other diagnostic products, especially in Europe and Asia now: "Predictive and companion diagnostics are more and more important in the oncological area, since there are various treatment options. Together with VIROAD we can realize a rapid market access in China in addition to the core markets of Europe. Our current focus is on cell enumeration as a prognostic biomarker in the main oncological indications. Further, we are currently working on molecular assays, to detect genetic changes of CTCs on DNA and RNA level. Especially, therapy decisive measures in non-small cell lung cancer (NSCLC) are in our focus. The easy access to CTCs from the bloodstream using our GILUPI CellCollector® - when compared to tissue biopsy - particular for the detection of resistance mutations makes our Liquid Biopsy concept very attractive."

Xu Baozhi, general manager of the Chinese medical technology company VIROAD, emphasizes "The products of GILUPI have met the strong demand in our Chinese market. The population in our country is aging, and the market for diagnostics is growing dynamically. We are therefore looking forward to expand with our German partner. "




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


GILUPI GmbH is a medical device company founded in 2006 with focus on the development and production of innovative products for the in vivo isolation of rare cells from the blood circulation. Currently, the main focus of GILUPI is the diagnostics market for cancer. Individual oncological targeted therapies become increasingly important in personalized medicine. The identification of the right drug for the individual patient is todays challenge in clinical practice. To address this medical need, the GILUPI CellCollector® is used to enrich rare cells by immune capture - i.e. directly "fishing" of CTCs in the patient's bloodstream. This methodology has proven to yield highest cell numbers and patient positivity rates in various cancer types. Applying diagnostic analyses ranging from immunostaining, DNA- and RNA-based methods, the isolated cells can be characterized and/or analyzed down to a molecular level.
The GILUPI CellCollector® is the first in vivo CTC isolation product worldwide that is CE approved. For further information visit



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).

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.
