Fuchs TA, Brill A, Wagner DD. DNA and the receptor for advanced glycation end products (RAGE) were necessary for induction of NET associated platelet aggregation. Chloroquine has been used for many years to treat patients with malaria, lupus, and rheumatoid arthritis, but more recently, hydroxychloroquine has been evaluated as a treatment for pancreatic cancer, with encouraging preliminary results [18]. Diaz JA, Fuchs TA, Jackson TO, Kremer Hovinga JA, Lammle B, Henke PK, et al. Pancreatic ductal adenocarcinoma is one of the deadliest carcinomas and is characterized by highly tumorigenic and metastatic cancer stem cells (CSC). Epub 2014 May 12. Incidence of venous thromboembolism and its effect on survival among patients with common cancers. 2013;2(2):e22946. 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). Google ScholarÂ. Platelet aggregation was assessed using collagen-activated impedance aggregometry. 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. The primary outcome for hypercoagulability was the coagulation index, a value that incorporates all measurements from the TEG curve [20]. Cancer Res. CAS  NETosis: a new factor in tumor progression and cancer-associated thrombosis. Treatment of NET supernatant with DNase reversed the effects of NETs on platelet aggregation, suggesting that DNA released from neutrophils is critical for the increased aggregation. McDonald B, Davis RP, Kim SJ, Tse M, Esmon CT, Kolaczkowska E, et al. Hydroxychloroquine is approved for the treatment of non-cancerous illnesses such as rheumatoid arthritis and systemic lupus erythematous. Meng H, Yalavarthi S, Kanthi Y, Mazza LF, Elfline MA, Luke CE, et al. 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. J Exp Med. 1975;41(12):761–6. Neutrophil and fibrinogen conjugates in the pancreatic tumor microenvironment. Woei AJFJ, Tesselaar ME, Garcia Rodriguez P, Romijn FP, Bertina RM, Osanto S. Tissue factor-bearing microparticles and CA19.9: two players in pancreatic cancer-associated thrombosis? also showed that pancreatic cancer NETs promoted platelet adhesion and that these effects could be reversed with DNase [11]. NETs and down-stream signaling pathways represent a novel target for further research on cancer associated thrombosis [15]. Mice were treated with DNase I (Sigma Aldrich, St Louis, MO, USA) for 5 consecutive daily intraperitoneal injections (5 mg/kg) prior to sacrifice. By using this website, you agree to our The NET inhibitor chloroquine reduces platelet aggregation, reduces circulating tissue factor and decreases hypercoagulability on TEG. Treatment with the autophagy inhibitor chloroquine results in a reversal of hypercoagulability in pancreatic cancer by diminishing NET mediated platelet aggregation and release of circulating tissue factor and improving coagulation index on TEG. More than two previous chemotherapy regimens for the treatment of metastatic pancreatic cancer, Uncontrolled brain or leptomeningeal metastases, History of macular degeneration, visual field changes, retinal disease, or cataracts that would interfere with funduscopic eye examinations, History of allergic reactions attributed to compounds of similar chemical or biologic composition to hydroxychloroquine, Previous treatment with chloroquine or hydroxychloroquine for other indications, such as rheumatoid arthritis, SLE or malaria prophylaxis, Prior treatment with any investigational drug within the preceding 4 weeks, Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter absorption of hydroxychloroquine. Patients received 600 mg hydroxychloroquine orally twice per day. Br J Cancer. Blood. Results are reported from at least two independent experiments performed with at least duplicate samples. Trial Names: Trametinib and Hydroxychloroquine in Treating Patients With Pancreatic Cancer (THREAD). Trials to test hydroxychloroquine, an inhibitor of autophagy, for pancreatic cancer are in progress. 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. Hydroxychloroquine may inactivate these pathways and results in the death of pancreatic cancer … Priming of neutrophils toward NETosis promotes tumor growth. In patients treated as part of a phase I/II dose escalation trial of preoperative hydroxychloroquine with gemcitabine, the 90 day VTE rate was 3% (n = 1 of 33) [18]. Binimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Part of Following standard IHC deparaffinization protocol, sections were subject to antigen retrieval using 10 mM Citric acid buffer. Importance: Autophagy is a mechanism of treatment resistance to chemotherapy that has a role in the maintenance of pancreatic cancer. Khorana AA, Ahrendt SA, Ryan CK, Francis CW, Hruban RH, Hu YC, et al. For clinical outcomes, venous thromboembolism was defined as any venous thrombosis including deep vein thrombosis, pulmonary embolism, mesenteric thrombosis and catheter associated thrombosis. (DOCX 15 kb), Table S2. Platelet aggregometry was performed on RAGE knockout (RAGE KO) animals, which have global genetic depletion of RAGE. PAD4 KO mice are unable to form NETs as a result of genetic deficiency in protein arginine deiminase 4, an enzyme critical for NET formation that citrullinates histones to allow for DNA unwinding and expulsion from the cell [22].

Demers M, Krause DS, Schatzberg D, Martinod K, Voorhees JR, Fuchs TA, et al. Among all patients, those with VTE had a mean increase of 6 ng/mL with treatment compared with decrease of 70 ng/mL in those that did not have VTE (p < 0.05). We demonstrate that tumor burdened mice are hypercoagulable on TEG and treatment with chloroquine reverses this hypercoagulopathy. ], Progression-Free Survival [ Time Frame: Disease was evaluated radiologically at baseline and every 2 months on treatment. Zohav E, Almog B, Cohen A, Levin I, Deutsch V, Many A, et al. Wolpin BM, Rubinson DA, Wang X, Chan JA, Cleary JM, Enzinger PC, Fuchs CS, McCleary NJ, Meyerhardt JA, Ng K, Schrag D, Sikora AL, Spicer BA, Killion L, Mamon H, Kimmelman AC. 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 (p = 0.053, Fig. 5c). Cells were initially plated in Hank’s Balanced Salt Solution (HBSS, Gibco, Grand Island, NY, USA), then to form NETs, HBSS was removed and cells were stimulated with 500 nM phorbol 12-myristate 13-acetate (PMA, Sigma, St. Louis, MO, USA) in RPMI. 2004;303(5663):1532–5. 2015;22(6):326–34. Google ScholarÂ. 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. Given its well-established use, favorable safety profile and anti-tumor effects, CQ is a suitable treatment to decrease VTE rate in patients with pancreatic cancer. The company’s cancer drug, devimistat, has received orphan status from the agency for treating clear-cell sarcoma, pancreatic cancer, and other diseases. Oncologist. Autophagy is a catabolic pathway that permits cells to recycle intracellular macromolecules, and its inhibition reduces pancreatic cancer growth in model systems. Tumor burdened mice had heightened platelet activation compared to sham controls (A). Chloroquine and hydroxychloroquine decrease CXCL12-mediated proliferation in pancreatic cancer cell lines. All patients signed informed consent prior to participation in these clinical protocols. Despite various approaches for thromboprophylaxis, both VTE and subsequent treatments for it are significant sources of morbidity and mortality. Patients were considered to have experienced PD if they demonstrated either clinical deterioration resulting in withdrawal or PD per RECIST 1.0 criteria: At least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Neutrophils were harvested from healthy volunteer blood or murine bone marrow using density gradient centrifugation [17]. Patients remained on treatment indefinitely without the occurrence of disease progression, unacceptable adverse events, patient withdrawal, or discontinuation per MD decision. 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. Thorson CM, Van Haren RM, Ryan ML, Curia E, Sleeman D, Levi JU, et al. A recently described phenomenon that occurs in activated neutrophils, neutrophil extracellular trap formation or NETs, has been described as a potential contributor to hypercoagulability. For the orthotopic pancreatic cancer model, wild type, RAGE KO and PAD4 KO mice were randomly allocated and injected with 1 × 106 Panc02 cells (National Cancer Institute repository, 2008) into the tail of the pancreas through a limited laparotomy. Blood from RAGE knockout mice had decreased aggregation after treatment with 100 μL of NET supernatant compared with WT (d, AUC 25.5 ± 2.6 vs. 43.3 ± 3.9, n = 4, p < 0.05). 2006;166(4):458–64. Google ScholarÂ. Phase II Study of Hydroxychloroquine in Previously Treated Patients With Metastatic Pancreatic Cancer. Neutrophil extracellular traps promote thrombin generation through platelet-dependent and platelet-independent mechanisms. Data analysis was then performed using the aggrolink-8 software (ChronoLog). Median survival follow-up in this study cohort was 60 days (95% CI: 40-184). P-values < 0.05 were considered statistically significant. CR or PR confirmation is required >/= 4 weeks. Safety and biologic response of pre-operative autophagy inhibition in combination with gemcitabine in patients with pancreatic adenocarcinoma. 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. DNA is released from neutrophils into the circulation during NET formation, therefore this data suggests that NETs may play a role in VTE in patients with pancreatic cancer. Choosing to participate in a study is an important personal decision. Chloroquine has previously been studied for prevention of perioperative VTE in orthopedic surgery patients, however these studies had mixed results and the precise mechanism was not completely understood [46, 47]. 2005;44(3):293–8. Chloroquine or combinations of chloroquine and chemotherapy demonstrate antitumor properties in orthotopic transplantable and genetically engineered models of pancreatic cancer (1). Google ScholarÂ. We have previously demonstrated that pancreatic cancer primes neutrophils to become more prone to NET formation and identified NETs within pancreatic tumors [13]. Clinical trials in patients with pancreatic cancer have shown that hydroxychloroquine, combined with standard chemotherapy, increases a patient's response to chemotherapy. Experimental: Hydroxychloroquine 600 mg b.i.d. We next examined the impact of hydroxychloroquine (HCQ) on circulating tissue factor in patients with pancreatic cancer using serum from our recently completed randomized clinical trial of preoperative gemcitabine/nab-paclitaxel with or without HCQ. Treatment with CQ resulted in a decrease in the coagulation index in cancer burdened animals (Fig. 5b). Risk of site-specific cancer in incident venous thromboembolism: a population-based study. Mice from tumor bearing animals demonstrated significantly greater platelet aggregation in response to collagen stimulation (Fig. 1a) and had heightened platelet activation as measured by %CD62P positive platelets (Additional file 1: Figure S1A). 2015;110(3):20. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions. Brinkmann V, Reichard U, Goosmann C, Fauler B, Uhlemann Y, Weiss DS, et al. 2015;13(7):1310–9. However, given that DNA is a nonspecific marker for NETs and that circulating DNA in cancer patients is likely derived from multiple sources [52] we are unable to conclude that DNA released from NETs is driving VTE in these patients. Neutrophil extracellular traps: a new link to cancer-associated thrombosis and potential implications for tumor progression. All experimental animal procedures were reviewed and approved by the Institutional Animal Care and Use Committee of the University of Pittsburgh (Protocol # 14084123). In the current study, inhibition of NETs with chloroquine resulted in decreased platelet aggregation and lower levels of circulating tissue factor. 2012;109(32):13076–81. Buprenex (0.1 mg/kg IP BID for 3 days) was administered for postoperative pain control. PubMed Google Scholar. 1974;3(5923):94–5. J Thromb Haemost. Curve analysis was performed using Haemonetics TEG software (version 4.2.3) and the R, K, angle, and MA were measured. Front Immunol. Because the receptor for advanced glycation end products (RAGE) is a known receptor for DNA [23] and induces autophagy and NET formation in pancreatic cancer [13], we sought to evaluate the role of RAGE in NET mediated platelet aggregation. The finding suggests that resistance to immunotherapy due to internalisation of MHC-I seen in pancreatic cancer cells could be at work in other cancer types. PAD4 KO mice, unable to form NETs had diminished platelet activation. Here is some info that you might find interesting: 2012;3:385. Resected pancreatic specimens from patients with pancreatic adenocarcinoma were stained and imaged using the following protocol. Hydroxychloroquine is an autophagy inhibitor. Biochim Biophys Acta. (A) PANC-1, (B) Hs-766T, and (C) MIAPaCa-2 cells were pretreated with chloroquine or hydroxychloroquine (0.1 µM) for 30 minutes after which cells were exposed to CXCL12 (200 ng/ml) for 72 hours. Formation of ex vivo NETs. Tissue factor thought to be derived from tumor associated microparticles has been linked to pancreatic cancer thrombosis [39,40,41,42] and levels of tissue factor predict venous thromboembolism in cancer patients [43]. CAS  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). Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Tissue factor, a transmembrane receptor typically found in subendothelial cells that binds to factor VII to initiate the extrinsic pathway when the endothelium is damaged is also released from neutrophils during NET formation [25, 26]. Read our, ClinicalTrials.gov Identifier: NCT01273805, Interventional NETs promote hypercoagulability through platelet aggregation. Patients without an event were censored at date of last disease evaluation. CQ treatment led to a decrease in circulating tissue factor in tumor bearing mice (d, 186.9 ± 5.6 vs. 228.2 ± 21 pg/mL, p < 0.05). In vivo treatment with DNase I resulted in decreased aggregation in tumor bearing mice (b, AUC 22.1 ± 2.3 vs. 38.4 ± 2.1, n = 4, p < 0.05). Plasma was collected from blood drawn into 3.2% sodium citrate tubes. Thromb Res. Br Med J. Neutrophil extracellular traps (NETs) occur when activated neutrophils release their intracellular contents, including DNA, histones, granules and proteins, into the surrounding tissue or circulation [12]. Importantly, CQ had minimal effects in PAD4KO mice, suggesting that it decreases platelet aggregation through inhibition of NETs (c). Tissue factor ELISA was performed on serum from orthotopic mice, demonstrating that tumor burdened mice had elevated levels of circulating tissue factor compared to sham (a, 255 ± 49 vs. 159 ± 26 pg/mL, p < 0.05). In vivo role of neutrophil extracellular traps in antiphospholipid antibody-mediated venous thrombosis. Chang X, Yamada R, Sawada T, Suzuki A, Kochi Y, Yamamoto K. The inhibition of antithrombin by peptidylarginine deiminase 4 may contribute to pathogenesis of rheumatoid arthritis. Treatments currently in trials for pancreatic cancer are best!! volume 18, Article number: 678 (2018) Proc Natl Acad Sci U S A. ], Grade 4-5 Treatment-Related Toxicity [ Time Frame: Adverse events were assessed each cycle throughout treatment. These studies were not powered to evaluate the exploratory endpoints including in the current manuscript. Fuchs TA, Brill A, Duerschmied D, Schatzberg D, Monestier M, Myers DD Jr, et al. Hydroxychloroquine Cures Cancer. Thromboelastograms (TEGs) were performed to assess hypercoagulability and changes associated with treatment. PubMed Central  This study reports correlative data from two clinical trials that registered with clinicaltrials.gov, NCT01128296 (May 21, 2010) and NCT01978184 (November 7, 2013). To substantiate the role of NETs in upregulated platelet function, we injected orthotopic tumor into the pancreas of PAD4 KO and syngeneic wild type controls. Knockout mice deficient in the receptor for advanced glycation end products (RAGE−/−, SVEV129 x C57/BL6), a critical inducer of autophagy and NET formation in pancreatic cancer, were also studied and made available by the late Angelika Bierhaus (Heidelberg). 2009;276(22):6763–72. Pre-existing hypercoagulability in patients undergoing potentially curative cancer resection. Pancreatic cancer is associated with a hypercoagulable state resulting in a high risk of venous thromboembolism (VTE), which affects up to 40% of patients during their course of disease [ 1, 2, 3 ]. (DOCX 109 kb), Figure S3. (DOCX 489 kb), Table S1. 2014;34(9):1977–84. 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. Paricalcitol (a form of vitamin D) works by blocking a signal in the cancer cells that leads to growth and spreading of the tumor. Since DNA is known to increase platelet aggregation in sepsis and deep vein thrombosis, we suspected that DNA released during NETosis would also mediate platelet aggregation in pancreatic cancer [33, 34, 38]. Participants who have had chemotherapy or radiotherapy within 2 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier. The addition of NET supernatant to RAGE knockout blood did not result in increased platelet aggregation. Platelet activation was assessed by analyzing expression of P-selectin (CD62P) by flow cytometry using an APC-conjugated anti-CD62P monoclonal antibody (2 μg/ml, mouse IgG1κ; eBioscience, San Diego, CA) or isotype control antibody (eBioscience) in platelet rich plasma (PRP), obtained by platelet isolation centrifugation. Levels of circulating tissue factor, the initiator of extrinsic coagulation, were measured using ELISA. Slides were washed three times with BSA solution and incubated for 1 h at RT with Alexa 488 donkey anti mouse secondary antibody (A21202, Invitrogen) diluted 1:500, combined with donkey anti rabbit CY3 (711–165-152, Jackson Immuno) 1:1000, and donkey anti sheep Cy5 (713–175-147, Jackson) in BSA solution.
