To determine the role of NETs in platelet aggregation in our cancer model, we first examined platelet activation and aggregation in mice injected with orthotopic tumor and sham injected controls. In a more recent randomized trial of preoperative gemcitabine and nab-paclitaxel with or without hydroxychloroquine, the VTE rate of patients treated with hydroxychloroquine was 9.1% compared to 30% in patients treated with gemcitabine/nab-paclitaxel alone (pâ=â0.053, Fig.Â 5c). Treatment of human (b) and murine (c) blood with NET supernatant led to a dose dependent increase in platelet aggregation compared with treatment with media control. (DOCX 489 kb), Table S1. Abdol Razak N, Elaskalani O, Metharom P. Pancreatic Cancer-induced neutrophil extracellular traps: a potential contributor to Cancer-associated thrombosis. Meanwhile, questions arose of whether people who were already taking the drug to treat certain autoimmune diseases would perhaps be protected from COVID-19. My treatment included chemo, plus IV Paricalcitol and hydroxychloroquine). 2000;98(5):411â21. Neutrophil-platelet interactions are increasingly recognized as an important collaboration in promoting malignancy and thrombosis . Individuals with the following cancers are eligible if diagnosed and treated within the past three years: cervical cancer in situ, and basal cell or squamous cell carcinoma, HIV-positive individuals on combination antiretroviral therapy. Importantly, CQ had minimal effects in PAD4KO mice, suggesting that it decreases platelet aggregation through inhibition of NETs (c). Diaz JA, Fuchs TA, Jackson TO, Kremer Hovinga JA, Lammle B, Henke PK, et al. This phase I trial studies the best dose of hydroxychloroquine when given together with binimetinib in treating patients with KRAS gene mutated pancreatic cancer that has spread to other places in the body (metastatic).

Pancreatic ductal adenocarcinoma is one of the deadliest carcinomas and is characterized by highly tumorigenic and metastatic cancer stem cells (CSC). However, because CQ also has direct antiplatelet effects, it is difficult to completely attribute all its effects to inhibition of NETosis. TEG has been most thoroughly studied in patients during massive bleeding from trauma as a rapidly available test to direct transfusion of blood products, however, it is becoming more frequently utilized to identify hypercoagulability . Median PFS follow-up in this study cohort was 46.5 days (95% CI 33-61). Manage cookies/Do not sell my data we use in the preference centre. Carter AE, Eban R.

Hydroxychloroquine (HCQ) is a 4-aminoquinoline agent that has been used for >50 years to prevent or to treat malarial infections and later also to treat autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. Effect of citrullination on the function and conformation of antithrombin. Median duration of treatment for this study cohort was 34 days. NETs promote hypercoagulability through platelet aggregation. In the current study, inhibition of NETs with chloroquine resulted in decreased platelet aggregation and lower levels of circulating tissue factor. Chloroquine and hydroxychloroquine decrease CXCL12-mediated proliferation in pancreatic cancer cell lines. Please remove one or more studies before adding more. Importantly, treatment with CQ in PAD4 KO mice, incapable of forming NETs, had minimal effect, suggesting that CQ decreases platelet aggregation through inhibition of NETs. ArticleÂ Venous thromboembolism predicts poor prognosis in irresectable pancreatic cancer patients. 100Â Î¼g/mL chloroquine (MP Biomedicals) was added to whole blood for 10Â min prior to aggregation. All together our findings support additional clinical trials with hydroxychloroquine to examine the ability of NET inhibition to lower the venous thromboembolism rate in patients with pancreatic and other cancer types.

Progression-free survival based on the Kaplan-Meier method is defined as the duration of time from study entry to time of objective progression on CT scan or the time of death for patients with clinical deterioration resulting in withdrawal from the trial. Large area scan images were captured with a Nikon A1confocal microscope (NIS Elements 4.4, Tokyo, Japan). This phase II trial investigates how well LY3214996 alone or in combination with hydroxychloroquine works in treating patients with pancreatic cancer. The slides were incubated for 1Â h at room temperature (RT) with primary antibodies for rabbit anti neutrophil elastase (ab68672, Abcam) at 1:200, sheep anti fibrinogen (ab61352, Abcam) 1:1000, and mouse anti tissue factor (ab17375, Abcam) 1:200, in 0.5% BSA solution. The addition of NET supernatant to RAGE knockout blood did not result in increased platelet aggregation. Overall survival estimated using Kaplan-Meier (KM) methods is defined as the time from study entry to death or date last known alive. Correlative data and samples from a randomized clinical trial of preoperative gemcitabine/nab-paclitaxel with and without hydroxychloroquine were studied and the impact of treatment on venous thromboembolism (VTE) rate was evaluated. Importantly, control sham mice appear to have a subtle increase in coagulation index with CQ treatment. The findings presented today focused on advanced pancreatic cancer patients who enrolled in XCELSIOR and were treated with a MEK inhibitor, trametinib, in combination with an autophagy inhibitor, hydroxychloroquine, a generic medication approved by the U.S. Food and Drug Administration (FDA) for treatment of malaria, as part of their clinical cancer care. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Results are reported from at least two independent experiments performed with at least duplicate samples. CASÂ Prior to injection, cells were cultured in RPMI 1640 media (Hyclone, Logan, UT, USA) with 10% fetal bovine serum, and PenStrep antibiotic (Gemini, West Sacramento, CA, USA) in a humidified incubator with 5% CO2. Addition of NET supernatant to murine whole blood increased platelet activation in a dose dependent fashion (B). 2014;12(12):2074â88. Med Oncol. Researchers in the laboratory have tested tumors from patients with pancreatic cancer and have discovered that they have certain pathways inside the cells that promote growth and survival of the tumor. Anesthesia was induced using isoflurane (2â5% inhalation), ketamine (90Â mg/kg IP) and xylazine (10Â mg/kg IP). Mice were treated with oral chloroquine administered in the drinking water (0.5Â mg/mL, MP Biomedicals, Solon, OH, USA). 21â23 20 15, PubMedÂ CQ treatment led to a decrease in circulating tissue factor in tumor bearing mice (d, 186.9âÂ±â5.6 vs. 228.2âÂ±â21Â pg/mL, pâ<â0.05). However, given that DNA is a nonspecific marker for NETs and that circulating DNA in cancer patients is likely derived from multiple sources  we are unable to conclude that DNA released from NETs is driving VTE in these patients. 2016;35(10):1078-85. Br J Cancer. Treatment with NET supernatant induced platelet aggregation in both human (Fig.Â 1b) and murine (Fig.Â 1c) blood in a dose dependent fashion and increased platelet activation (AdditionalÂ fileÂ 2: Figure S2B).

Espinola RG, Pierangeli SS, Gharavi AE, Harris EN. 2011;6(7):e22043. PAD4-mediated neutrophil extracellular trap formation is not required for immunity against influenza infection. Representative images from three individual patients are shown, demonstrating focal areas of elastase and fibrinogen in the tumor, suggesting interactions between neutrophils and thrombosis in the tumor microenvironment. ], Tumor Response Rate [ Time Frame: Disease was evaluated radiologically at baseline and every 2 months on treatment. 1Â mg/mL treatment of DNase I (Sigma Aldrich, St. Louis, MO, USA) was added to NET supernatant for 10Â min prior to treatment of whole blood. The receptor for advanced glycation end products (RAGE) enhances autophagy and neutrophil extracellular traps in pancreatic cancer. CR or PR confirmation is required >/= 4 weeks. 2009;276(22):6763â72. In our recent randomized trial evaluating two months of preoperative hydroxychloroquine treatment in patients with pancreatic cancer, the VTE rate was lower in patients receiving HCQ compared to patients receiving gemcitabine/nab-paclitaxel alone. 2014;34(9):1977â84.

Proceedings: AACR Annual Meeting 2018; April 14-18, 2018; Chicago, IL Autophagy, a regulated metabolic process that enables energy conservation in adverse environmental circumstances, has been shown in animal models to confer resistance to chemotherapy, which can be reversed by hydroxychloroquine (HCQ). Extracellular DNA traps promote thrombosis. By using this website, you agree to our Phase II Study of Hydroxychloroquine in Previously Treated Patients With Metastatic Pancreatic Cancer. Isolation of mouse neutrophils. Because autophagy is critical to the process of NET formation, we studied the novel use of the autophagy inhibitor chloroquine to target NET mediated hypercoagulability. After establishing safety in a Phase I run-in, 112 patients were … Neutrophil Extracellular Traps (NETs) promote platelet activation in murine pancreatic adenocarcinoma. Zohav E, Almog B, Cohen A, Levin I, Deutsch V, Many A, et al. There was no difference in pretreatment patient demographics between the two randomized groups (AdditionalÂ fileÂ 4: Table S1). Binimetinib may stop the growth of tumor cells … 2013;210(11):2447â63. Pre and post-treatment results were compared using paired t-test. In patients who had elevated levels of pre-treatment tissue factor, HCQ treatment led to a significant reduction, suggesting that the greatest effect of HCQ is seen in patients who may have upregulation of NETs at baseline. statement and Furthermore, RAGE KO mice, which have diminished NET formation, also had lower levels of serum tissue factor (Fig.Â 3b). ArticleÂ Cancer Res. ], Biochemical Response Rate [ Time Frame: Disease was evaluated radiologically at baseline and every 2 months on treatment. Petterson TM, Marks RS, Ashrani AA, Bailey KR, Heit JA. Surgery. There was no correlation between plasma DNA and VTE in HCQ treated patients. This phase II trial investigates how well paricalcitol and hydroxychloroquine work when combined with gemcitabine and nab-paclitaxel in treating patients with pancreatic cancer that has spread to other places in the body (advanced or metastatic). There was no difference in change in tissue factor with HCQ treatment in those patients with normal pre-treatment levels (mean change with treatment ââ55âÂ±â63 vs. +â3.1âÂ±â14Â pg/mL, pâ=â0.38, nâ=â19 gem/nab-paclitaxel alone, nâ=â18 gem/nab-paclitaxel + HCQ).

Arterioscler Thromb Vasc Biol. 2016;1863(3):392â400. Additionally, RAGE knockout mice had no differences in platelet aggregation at baseline, but had decreased platelet aggregation in tumor burdened mice compared with wild type. Wun T, White RH. Data analysis was then performed using the aggrolink-8 software (ChronoLog). 2012;7(9):e45427. Sections were blocked with 5% donkey serum in BSA solution for 45Â min. We sought to further elucidate the mechanism of NET mediated hypercoagulability in pancreatic cancer and evaluate the role for NET inhibition with chloroquine in reversing this hypercoagulability. Whole blood platelet aggregation was measured using impedance aggregometry (ChronoLog aggregometer, Model 700, Havertown, PA, USA). However, our group and others have demonstrated that chloroquine prevents NET formation [13, 14]; therefore some of the antiplatelet effects of HCQ may be secondary to reduction in NET mediated DNA release which increases platelet aggregation. Samples were placed into TEG cups 2Â IU of Heparinase I and 20Â Î¼L of 0.2Â mol/l CaCl2 was added. That's a no. Funding was also graciously provided by philanthropic donors, including the Emma Clyde Hodge Memorial Fund. Supernatant was collected after 4Â h and the formation of NETs was confirmed by measuring supernatant DNA using Quant-iT Picogreen (Invitrogen, Grand Island, NY, USA, MP07581) and by fluorescence microscopy to visualize NET formation using DNA staining with Hoechst (AdditionalÂ fileÂ 1: Figure S1). HCQ led to a statistically greater reduction in tissue factor in those patients who had elevated tissue factor prior to treatment, defined by preoperative level greater than the median (40Â ng/mL), (ââ240âÂ±â120 vs. -8.74âÂ±â26.1Â pg/mL, pâ<â0.05, Fig.Â 4e).
