    Publications Last Posters hPG80 Main Scientific Publications Last updated: Jully 2, 2021 Prognostic Value of Plasma hPG 80 (Circulating Progastrin) in Metastatic Renal Cell Carcinoma ​ Jan, 2021 Simple Summary Metastatic renal cell carcinoma (mRCC) accounts for one-third of all newly diagnosed renal cell cancers. A better understanding of the biology and molecular basis of disease progression has resulted in several drug targets being identified and led to approval of several new drugs for treating mRCC in the past decade. A growing need has emerged for identifying novel molecular tumor biology based and stage-specific prognostic and predictive biomarkers in mRCC reflective of biology beyond the currently available prognostic models which are solely based on clinical characteristics. We investigated hPG 80 (circulating progastrin), which is associated with kidney cancer biology and found that hPG 80 levels is both an independent prognostic marker in mRCC and also improves current clinical prognostic models. This will help stratify mRCC patients more accurately in future and improve the management of mRCC patients. Abstract Precise management of kidney cancer requires the identification of prognostic factors. hPG 80 (circulating progastrin) is a tumor promoting peptide present in the blood of patients with various cancers, including renal cell carcinoma (RCC). In this study, we evaluated the prognostic value of plasma hPG 80 in 143 prospectively collected patients with metastatic RCC (mRCC). The prognostic impact of hPG 80 levels on overall survival (OS) in mRCC patients after controlling for hPG 80 levels in non-cancer age matched controls was determined and compared to the International Metastatic Database Consortium (IMDC) risk model (good, intermediate, poor). ROC curves were used to evaluate the diagnostic accuracy of hPG 80 using the area under the curve (AUC). Our results showed that plasma hPG80 was detected in 94% of mRCC patients. hPG 80 levels displayed high predictive accuracy with an AUC of 0.93 and 0.84 when compared to 18–25 year old controls and 50–80 year old controls, respectively. mRCC patients with high hPG 80 levels (>4.5 pM) had significantly lower OS compared to patients with low hPG 80 levels (<4.5 pM) (12 versus 31.2 months, respectively; p = 0.0031). Adding hPG 80 levels (score of 1 for patients having hPG 80 levels > 4.5 pM) to the six variables of the IMDC risk model showed a greater and significant difference in OS between the newly defined good-, intermediate- and poor-risk groups (p = 0.0003 compared to p = 0.0076). Finally, when patients with IMDC intermediate-risk group were further divided into two groups based on hPG 80 levels within these subgroups, increased OS were observed in patients with low hPG 80 levels (<4.5 pM). In conclusion, our data suggest that hPG 80 could be used for prognosticating survival in mRCC alone or integrated to the IMDC score (by adding a variable to the IMDC score or by substratifying the IMDC risk groups), be a prognostic biomarker in mRCC patients.

In colorectal cancer, hPG80 (progastrin) is released from tumor cells, promotes cancer stem cells (CSC) self-renewal and is detected in the blood of patients. Because the gene GAST that encodes hPG80 is a target gene of oncogenic pathways that are activated in many tumor types, we hypothesized that hPG80 could be expressed by tumors from various origins other than colorectal cancers, be a drug target and be detectable in the blood of these patients. […] Research in context Evidence before study The National Cancer Institute recently highlighted the need forbiomarkers to improve early detection of cancers, monitor treatment effects and detect disease relapses. Therefore, the identification of a new tumor blood-based marker with broad expression across tumor types might have a significant impact on diagnostic and follow-up of patients. hPG80 (progastrin) was shown to be over-expressed in human colorectal tumor cells. Interestingly, GAST is a direct target of the Wnt/ß-catenin/Tcf4 oncogenic pathway. Since this pathway is activated inmany other cancers and plays a major function in cancer stem cells survival, we hypothesized that hPG80 (i) might be expressed by other types of cancers, and would be present in the blood of patients with tumors different from colorectal cancers and (ii) might be a drug target for various type of cancers. ​ Added value of this study Here we show that hPG80 is expressed by the tumor and present in the blood of 11 different types of cancer patients. Two retrospective kinetic studies where blood samples were collected regularly from cancer patients undergoing different treatments revealed strong associations between longitudinal hPG80 . ..... concentrations and anti-cancer treatment efficacy. We provide data showing the decrease of hPG80 after surgery in a cohort of patients with peritoneal involvements from gastroin-testinal cancers, treated with peri-operative chemotherapy regimens and cytoreductive surgery. We also show the correlationbetween hPG80 levels and standard imaging in a cohort of patients with hepatocellular carcinoma, managed with local or systemic treatments, including patients with no detectable levels of alpha-fetoprotein. Finally, we show that targeting hPG80 with our humanized antibody decreases self-renewal capacity of cancer stem cells from various origins. ​ Implications of all available evidence The technology we developed to detect hPG80 in the blood isr obust, reliable and inexpensive, making this test easy to implement by oncologists. This technology could be used to improve early cancer diagnosis and treatment efficacy monitoring. Furthermore, in this study we show that our anti-hPG80 therapeutic antibody, that was initially found to target the Wnt pathway and decrease self-renewal capacity in cancer stem cells from colorectal cancer, is envisioned to have the same effect on tumors from other origins. + Direct Comparison of Diagnostic Performance of 9 Quantitative Fecal Immunochemical Tests for Colorectal Cancer Screening ​ Sep, 2017 Gastroenterology, 2017 September Authors : Anton Gies1, Katarina Cuk2, Petra Schrotz-King1, Hermann Brenner A variety of fecal immunochemical tests (FITs) for hemoglobin (Hb) are used in colorectal cancer screening. It is unclear to what extent differences in reported sensitivities and specificities reflect true heterogeneity in test performance or differences in study populations or varying pre-analytical conditions.

She is therefore naturally looking for the "key" to this reversion. ​ In 2003, in her laboratory, her team and herself observed a protein that needs to come out of the tumor cell and re-interact with it to exert its effects on the tumor cell. ​ She believes that this protein, resulting from a set of disorders linked to the Wnt signaling pathway (highly involved in tumorigenesis), may be the key she is looking for. ​ She is modeling an experiment to demonstrate that neutralizing this protein can regulate the pathway that generated it. This approach seemed absurd to her team. Neutralizing the product of a mechanism to regulate the said mechanism, the idea is far-fetched! ​ To the surprise of sceptics, the experiment is conclusive, demonstrating for the first time that the tumor mechanism can be reverted into a solid tumor. ​ In a healthy individual, this protein, progastrin, is the precursor of gastrin, it is present in the G cells of the stomach, it is not found in the blood. In a patient with cancer (any cancer to date), it is secreted by the tumor cell of the organ affected by this cancer, it is then called hPG80. We’ve so far detected hPG80 in the blood of 83% cancer patients. Moreover, 100% of tumors produce hPG80[1]. ​ Dominique Joubert now knows that what has just been proven will simply change the history of cancer! She also knows that there is another equally challenging round ahead: bringing together all the energy, resources and expertise needed to ensure that a demonstration of basic research is translated into solutions for physicians, for the benefit of patients. ​ [1].

    hPG80 Main Scientific Publications Publications Last Posters hPG80 and cancer: A new blood biomarker in development for patient monitoring June 2022 Abstract Recent technological advances coupled with our improved understanding of the molecular and cellular mechanisms associated with cancer development have enabled better overall patient care. Among the newly identified biomarkers such as circulating tumor DNA or circulating tumor cells, hPG80 (circulating progastrin) that is easy to detect and quantify by a simple ELISA assay has the potential to become a new routine clinical tool in oncology if on-going studies validated its utility. Indeed, on the one hand, hPG80 was found in the blood of patients with different tumors (colorectal, pancreatic, liver, lung, stomach, kidney cancers) at a significantly higher concentration than in healthy donors. Moreover, some studies suggested a potential association between hPG80 concentration changes and anti-cancer treatment efficacy in patients with gastro-intestinal and hepatocellular carcinomas. Finally, hPG80 might be a prognostic factor for overall survival in metastatic renal cell carcinoma cancer (mRCC) and in hepatocellular carcinoma (HCC). If these hypotheses were validated, hPG80 might help better stratify patients according to their prognosis, and also become a tool to monitor relapse and predict treatment response. Prospective validation studies are on-going.

Human circulating progastrin (hPG80) can be easily measured in plasma by ELISA. This study is the first to examine hPG80 in NENs. The study demonstrated increased levels of hPG80 in all sub-types of NENs, with a high sensitivity and specificity demonstrated. Plasma hPG80 in NENs may be a diagnostic blood biomarker for both low- and high-grade NENs; further study is warranted. A prospective multi-center trial is ongoing in NET to evaluate hPG80 as a means of monitoring disease (NCT04750954). Abstract Current blood-based biomarkers for neuroendocrine neoplasms (NENs) lack both sensitivity and specificity. Human circulating progastrin (hPG80) is a novel biomarker that can be easily measured in plasma by ELISA. This study is the first to examine hPG80 in NENs. Plasma hPG80 was quantified from 95 stage IV NEN patients, using DxPG80technology (ECS Progastrin, Switzerland) and compared with hPG80 concentrations in two cohorts of healthy donor controls aged 50–80 (n = 252) and 18–25 (n = 137). Median hPG80 in NENs patients was 5.54 pM compared to 1.5 pM for the 50–80 controls and 0.29 pM the 18–25 cohort (p < 0.0001). Subgroup analysis revealed median hPG80 levels significantly higher than for either control cohort in neuroendocrine carcinoma (NEC; n = 25) and neuroendocrine tumors (NET; n = 70) including the small-cell lung cancer (SCLC) sub-cohort (n = 13). Diagnostic accuracy, estimated by AUCs, was high for NENs, as well as both sub-groups (NEC/NET) when compared to the younger and older control groups. Plasma hPG80 in NENs may be a diagnostic blood biomarker for both low- and high-grade NENs; further study is warranted. A prospective multi-center trial is ongoing in NET to evaluate hPG80 as a means of monitoring disease (NCT04750954).

The diagnosis of HCC is usually based on non-invasive criteria using detection of a liver nodule in abdominal ultrasonography or high serum alpha-fetoprotein (AFP) levels. However, as it is only elevated in 60% of patients with HCC, AFP has limited accuracy, especially in early stages, as both a diagnostic and prognostic test. We investigated hPG80 (circulating progastrin), which is associated with liver cancer biology, and found that hPG80 levels is both an independent prognostic marker in HCC and used in combination with AFP, it improves the stratification of the patients in good and poor prognosis, especially for those patients at early-stage. This will help stratify HCC patients more accurately in the future and improve the management of these patients. Abstract Alpha-fetoprotein (AFP) is the most widely used biomarker for hepatocellular carcinoma (HCC) prognosis. However, AFP is not useful in establishing a prognosis for patients with a tumor in the early stages. hPG80 (circulating progastrin) is a tumor promoting peptide present in the blood of patients with various cancers, including HCC. In this study, we evaluated the prognostic value of plasma hPG80 in patients with HCC, alone or in combination with AFP. A total of 168 HCC patients were tested prospectively for hPG80 and analyzed retrospectively. The prognostic impact of hPG80 and AFP levels on patient survival was assessed using Kaplan-Meier curves and log-rank tests. hPG80 was detected in 84% of HCC patients. There was no correlation between hPG80 and AFP levels in the training and validation cohorts. Both cohorts showed higher sensitivity of hPG80 compared to AFP, especially at early stages. Patients with high hPG80(hPG80+) levels (optimal cutoff value 4.5 pM) had significantly lower median overall survival (OS) compared to patients with low hPG80 (hPG80−) levels (12.4 months versus not reached respectively, p < 0.0001). Further stratification by combining hPG80 and AFP levels (cutoff 100 ng/mL) improved prognosis in particular for those patients with low AFP level (hPG80−/AFP+ and hPG80−/AFP−, 13.4 months versus not reached respectively, p < 0.0001 and hPG80+/AFP+ and hPG80+/AFP−, 5.7 versus 26 months respectively, p < 0.0001). This was corroborated when analyses were performed using the BCLC staging especially at early stages. Our findings show that hPG80 could serve as a new prognostic biomarker in HCC. Used in combination with AFP, it improves the stratification of the patients in good and poor prognosis, especially for those patients with negative AFP and early-stage HCC.

We recently reported that hPG80 is detected in the blood of patients with cancers from different origins, suggesting its potential utility for cancer detection. To accurately measure hPG80 in the blood of patients, we developed the DxPG80 test, a sandwich Enzyme-Linked Immunosorbent Assay (ELISA). This test quantifies hPG80 in EDTA plasma samples. The analytical performances of the DxPG80 test were evaluated using standard procedures and guidelines specific to ELISA technology. We showed high specificity for hPG80 with no cross-reactivity with human glycine-extended gastrin (hG17-Gly), human carboxy-amidated gastrin (hG17-NH2) or the CTFP (C-Terminus Flanking Peptide) and no interference with various endogenous or exogenous compounds. The test is linear between 0 and 50 pM hPG80 (native or recombinant). We demonstrated a trueness of measurement, an accuracy and a variability of hPG80 quantification with the DxPG80 test below the 20% relative errors as recommended in the guidelines. The limit of detection of hPG80and the limit of quantification were calculated as 1 pM and 3.3 pM respectively. In conclusion, these results show the strong analytical performance of the DxPG80 test to measure hPG80 in blood samples.

The prognostic impact of hPG80 levels on overall survival (OS) in mRCC patients after controlling for hPG80 levels in non-cancer age matched controls was determined and compared to the International Metastatic Database Consortium (IMDC) risk model (good, intermediate, poor). ROC curves were used to evaluate the diagnostic accuracy of hPG80 using the area under the curve (AUC). Our results showed that plasma hPG80 was detected in 94% of mRCC patients. hPG80 levels displayed high predictive accuracy with an AUC of 0.93 and 0.84 when compared to 18–25 year old controls and 50–80 year old controls, respectively. mRCC patients with high hPG80 levels (>4.5 pM) had significantly lower OS compared to patients with low hPG80 levels (<4.5 pM) (12 versus 31.2 months, respectively; p = 0.0031). Adding hPG80 levels (score of 1 for patients having hPG80 levels > 4.5 pM) to the six variables of the IMDC risk model showed a greater and significant difference in OS between the newly defined good-, intermediate- and poor-risk groups (p = 0.0003 compared to p = 0.0076). Finally, when patients with IMDC intermediate-risk group were further divided into two groups based on hPG80 levels within these subgroups, increased OS were observed in patients with low hPG80 levels (<4.5 pM). In conclusion, our data suggest that hPG80 could be used for prognosticating survival in mRCC alone or integrated to the IMDC score (by adding a variable to the IMDC score or by substratifying the IMDC risk groups), be a prognostic biomarker in mRCC patients.

In colorectal cancer, hPG80 (progastrin) is released from tumor cells, promotes cancer stem cells (CSC) self-renewal and is detected in the blood of patients. Because the gene GAST that encodes hPG80 is a target gene of oncogenic pathways that are activated in many tumor types, we hypothesized that hPG80 could be expressed by tumors from various origins other than colorectal cancers, be a drug target and be detectable in the blood of these patients. […] Research in context Evidence before study The National Cancer Institute recently highlighted the need forbiomarkers to improve early detection of cancers, monitor treatment effects and detect disease relapses. Therefore, the identification of a new tumor blood-based marker with broad expression across tumor types might have a significant impact on diagnostic and follow-up of patients. hPG80 (progastrin) was shown to be over-expressed in human colorectal tumor cells. Interestingly, GAST is a direct target of the Wnt/ß-catenin/Tcf4 oncogenic pathway. Since this pathway is activated inmany other cancers and plays a major function in cancer stem cells survival, we hypothesized that hPG80 (i) might be expressed by other types of cancers, and would be present in the blood of patients with tumors different from colorectal cancers and (ii) might be a drug target for various type of cancers. ​ Added value of this study Here we show that hPG80 is expressed by the tumor and present in the blood of 11 different types of cancer patients. Two retrospective kinetic studies where blood samples were collected regularly from cancer patients undergoing different treatments revealed strong associations between longitudinal hPG80 . ..... concentrations and anti-cancer treatment efficacy. We provide data showing the decrease of hPG80 after surgery in a cohort of patients with peritoneal involvements from gastroin-testinal cancers, treated with peri-operative chemotherapy regimens and cytoreductive surgery. We also show the correlationbetween hPG80 levels and standard imaging in a cohort of patients with hepatocellular carcinoma, managed with local or systemic treatments, including patients with no detectable levels of alpha-fetoprotein. Finally, we show that targeting hPG80 with our humanized antibody decreases self-renewal capacity of cancer stem cells from various origins. ​ Implications of all available evidence The technology we developed to detect hPG80 in the blood isr obust, reliable and inexpensive, making this test easy to implement by oncologists. This technology could be used to improve early cancer diagnosis and treatment efficacy monitoring. Furthermore, in this study we show that our anti-hPG80 therapeutic antibody, that was initially found to target the Wnt pathway and decrease self-renewal capacity in cancer stem cells from colorectal cancer, is envisioned to have the same effect on tumors from other origins. + Direct Comparison of Diagnostic Performance of 9 Quantitative Fecal Immunochemical Tests for Colorectal Cancer Screening ​ Sep, 2017 Gastroenterology, 2017 September Authors : Anton Gies1, Katarina Cuk2, Petra Schrotz-King1, Hermann Brenner A variety of fecal immunochemical tests (FITs) for hemoglobin (Hb) are used in colorectal cancer screening. It is unclear to what extent differences in reported sensitivities and specificities reflect true heterogeneity in test performance or differences in study populations or varying pre-analytical conditions. We directly compared the sensitivity and specificity values with which 9 quantitative (laboratory-based and point-of-care) FITs detected advanced neoplasms (AN) in a single colorectal cancer screening study.

Subpopulations of cancer stem-like cells (CSC) are thought to drive tumor progression and posttreatment recurrence in multiple solid tumors. However, the mechanisms that maintain stable proportions of self-renewing CSC within heterogeneous tumors under homeostatic conditions remain poorly understood.

Global analysis. High levels of hPG80 before surgery. Decrease of hPG80 8h to 24h after surgery (From 3.08 pM to 1.57 pM; p=0.035). Individual analysis. 74.2% of the patients had a decrease of at least 25% of hPG80 levels after surgery. Sustained elevations in hPG80 concentrations after surgery could be suggestive of the presence of residual disease.

PROSTATE CANCER Elevated hPG80 levels in patients with advanced prostate cancer (aPCa)* (healthy blood donors 18 to 40 yo: median hPG80 = 0.37 pM vs aPCa: median hPG80 = 4.7 pM, p<0.0001). *aPCa includes metastatic hormone sensitive (mHSPC) and metastatic castration resistant (mCRPC) prostate cancer patients. Overall survival (OS) according to hPG80 levels evolution during follow-up. Patients with a serial increase of hPG80 had a worst overall survival compare to the other group (9.3 yo vs 12.4 yo, P = 0.019). Plasma Progastrin Level As A Prognostic Biomarker In Advanced Prostate Cancer.

KIDNEY CANCER Elevated hPG80 levels in patients with metastatic renal cell carcinoma (mRCC) (Cohort (healthy blood donors18-25 y/o): median hPG80 = 0.29 pM vs mRCC hPG80= 7.2 pM). We compared hPG80 levels with the MSKCC prognostic criteria for patient survival. In this score, patients are separated in 3 groups: good, intermediate and poor prognostic. hPG80 levels were higher within the MSKCC score poor prognostic group (p<0.001) (median 30.39 pM vs 6 pM and 9.34 pM in the good and intermediate group, respectively). hPG80 assay might be useful for defining subsets of mRCC patients with poor survival who need to be treated aggressively. Prognostic Impact Of Progastrin Levels In Blood Compared To MSKCC Based Clinical Prognosis In Metastatic Renal Cell Cancer Patients.

AACR 2019 - Poster #2289. 5 hPG80 for the Monitoring of Relapse (Tumor Activity) MONITORING FOR HEPATOCELLULAR CARCINOMA RECURRENCE Earlier detection of small lesions and the monitoring of recurrence may be improved with hPG80 as a supplemental blood-based biomarker, especially in AFP negative populations where there is limited information. Patients in remission following disease management have lower hPG80 concentrations compared to active cancers. 76% of patients with progressing disease during or after treatment had an increased hPG80 > 25%. Illustrative hPG80 longitudinal changes around and during disease management (baseline; remission; progression), with associated imaging obtained at the same times in a typical patient. Progastrin a new biomarker for hepatocellular cancer patient follow-up. Alexandre Prieur, Marie Dupuy, Pierre Liaud, Dominique Joubert and Eric Assenat. AACR 2019 - Poster # 2222.

MONITORING FOR OVARIAN CANCER RECURRENCE 70% of ovarian cancers are not diagnosed until stage III or IV where survival rates are low (48% after 5 years). As a result, cancer recurrence is high (70-95%) following standard treatment by surgery and combination chemotherapy. hPG80, as a blood-based biomarker used in conjunction with CA125, could improve the early detection of residual disease, treatment efficacy, and/or relapse following treatment.
