Vaccine Therapy in Treating Patients With Liver or Lung Metastases From Colorectal Cancer
Ontology highlight
ABSTRACT: RATIONALE: Vaccines made from a gene-modified virus and a person’s white blood cells may make the body build an effective immune response to kill tumor cells. Biological therapies, such as Granulocyte-macrophage colony-stimulating factor (GM-CSF), may stimulate the immune system in different ways and stop tumor cells from growing. Combining different types of biological therapies may kill more tumor cells.
PURPOSE: This randomized phase II trial is studying giving vaccine therapy together with dendritic cells to see how well it works compared to giving vaccine therapy together with GM-CSF in treating patients with liver or lung metastases from colorectal cancer removed by surgery.

Project description:RATIONALE: Vaccines made from a person’s cancer proteins may help the body build an effective immune response to kill cancer cells. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving vaccine therapy together with GM-CSF may make a stronger immune response and kill more cancer cells.
PURPOSE: This phase II trial is studying the side effects and how well giving vaccine therapy together with GM-CSF works in treating patients with CNS lymphoma.
Project description:RATIONALE: Combinations of biological substances in denileukin diftitox may be able to carry cancer-killing substances directly to the cancer cells. Vaccines made from a gene-modified virus and a person’s white blood cells may help the body build an effective immune response to kill cancer cells. Giving denileukin diftitox together with vaccine therapy may kill more cancer cells.
PURPOSE: This phase I trial is studying the side effects of giving denileukin diftitox together with vaccine therapy in treating patients with metastatic cancer that expresses carcinoembryonic antigen.
Project description:RATIONALE: Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy or kill tumor cells. Drugs used in chemotherapy, such as fluorouracil, leucovorin, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Giving combination chemotherapy after surgery may kill any remaining tumor cells. Sometimes, after surgery, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient.
PURPOSE: This phase II trial is studying how well GM-CSF and combination chemotherapy work in treating patients who are undergoing surgery for stage II or stage III colon cancer.
Project description:Effective stimulation of immune cells is crucial for the success of cancer immunotherapies. Current approaches to evaluate the efficiency of stimuli activating immune cells are mainly defined by known flow cytometry-based cell activation or cell maturation markers. This method however does not give a complete overview of the achieved activation state and may leave important side effects unnoticed. Here, we used an unbiased RNA sequencing (RNA-seq)-based approach to compare the capacity of four clinical-grade dendritic cell (DC) activation stimuli used to prepare DC-vaccines composed of various types of DC subsets; the already clinically applied GM-CSF and Frühsommer meningoencephalitis (FSME) prophylactic vaccine and the novel clinical grade adjuvants protamine-RNA (pRNA) complexes and CpG-P. We found that GM-CSF and pRNA have similar effects on their target cells, whereas pRNA and CpG-P induce stronger tType I interferon (IFN) expression than FSME. In general, the pathways most affected by all stimuli were related to immune activity and cell migration. GM-CSF stimulation, however, also induced a significant increase of genes related to nonsense-mediated decay, indicating a possible deleterious effect of this stimulus. Taken together, all novel stimuli appear to be promising alternatives. Our study demonstrates how RNA-seq based investigation of changes in a large number of genes and gene groups can be exploited for fast and unbiased, global evaluation of clinical-grade stimuli, as opposed to the general limited evaluation of a pre-specified set of genes, by which one might miss important biological effects detrimental for vaccine efficacy.
Project description:RATIONALE: Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Giving vorinostat together with lenalidomide may kill more cancer cells.
PURPOSE: This phase I trial is studying the side effects and best dose of vorinostat when given together with lenalidomide in treating patients with relapsed or refractory Hodgkin lymphoma or non-Hodgkin lymphoma.
Project description:GM-CSF is involved in immune complex (IC)-mediated arthritis. However, little is known about what is the cellular source of GM-CSF and how it is regulated during IC-mediated inflammation. Using novel GM-CSF reporter mice, we show that NK cells produce GM-CSF during an IC-mediated model of inflammatory arthritis. NK cells promoted STIA in a GM-CSF-dependent manner, as deletion of NK cells and selective removal of GM-CSF production by NK cells abrogated disease. Furthermore, we show that myeloid cell activation by GM-CSF is restrained by induction of JAK/STAT checkpoint inhibitor cytokine-inducible SH2-containing protein, CIS. Myeloid cells from CIS-deficient mice had exaggerated responses to GM-CSF, and these mice develop exacerbated STIA. Our data suggest that tissue NK cells may amplify joint inflammation in arthritis via GM-CSF production and thus represent a novel target in IC-mediated pathology. Endogenous CIS provides a key brake on signaling through the GM-CSF receptor and strategies that boost its function may provide an alternative anti-inflammatory approach.
Project description:To explore reovirus-macrophage interactions, we performed tandem mass tag (TMT)-based quantitative temporal proteomics on mouse bone marrow-derived macrophages (BMMs) generated with 2 cytokines, M-CSF and GM-CSF, representing anti- and pro-inflammatory macrophages, respectively. We quantified 6,863 proteins across five time points in duplicate, comparing M-CSF (M-BMM) and GM-CSF (GM-BMM) in response to OV. We find that GM-BMMs have lower expression of key intrinsic proteins that facilitate an anti-viral immune response, express higher levels of reovirus receptor protein JAM-A and are more susceptible to oncolytic reovirus infection compared to M-BMMs. Interestingly, although M-BMMs are less susceptible to reovirus infection and subsequent cell death, they initiate an anti-reovirus adaptive T cell immune response comparable to that of GM-BMMs. Taken together, these data describe distinct proteome differences between these two macrophage populations in terms of their ability to mount anti-viral immune responses.
Project description:Glomerulonephritis is a group of immune-mediated diseases that cause inflammation within the glomerulus and adjacent compartments of the kidney and is a major cause of end-stage renal disease. T cells are among the main drivers of glomerulonephritis. However, the T cell subsets, cytokine networks, and downstream effector mechanisms that lead to renal tissue injury are largely unknown, which has hindered the development of targeted therapies. Here, we identify a population of granulocyte-macrophage colony-stimulating factor (GM-CSF)–producing T cells that accumulates in the kidneys of patients with antineutrophil cytoplasmic antibody (ANCA)–associated glomerulonephritis, infiltrates the renal tissue in a mouse model of glomerulonephritis, and promotes tissue destruction and loss of renal function. Mechanistically, we show that GM-CSF–producing T cells license monocyte-derived cells to produce matrix metalloproteinase 12 (MMP12), which cleaves components of the glomerular basement membrane and exacerbates renal pathology. Moreover, targeting GM-CSF or MMP12 reduced disease severity in mice with glomerulonephritis. Together, these findings provide a mechanistic rationale for the immunopathology of T cell–mediated diseases and identify this GM-CSF monocyte–derived cells–MMP12 axis as a promising therapeutic target for the treatment of glomerulonephritis.

ABSTRACT
Combined virotherapy and immunotherapy has been emergingas a promising and effective cancer treatment for some time.Intratumoural injections of an oncolytic virus instigate an immunereaction in the host, resulting in an influx of immune cells tothe tumour site. Through combining an oncolytic viral vector withimmunostimulatory cytokines an additional antitumour immuneresponse can be initiated, whereby immune cells induce apoptosisin both uninfected and virus infected tumour cells. We developa mathematical model to reproduce the experimental results fortumour growth under treatment with an oncolytic adenovirus co-expressing the immunostimulatory cytokines interleukin 12 (IL-12)and granulocyte-monocyte colony stimulating factor (GM-CSF). Byexploring heterogeneity in the immune cell stimulation by thetreatment, we find a subset of the parameter space for the immunecell induced apoptosis rate, in which the treatment will be lesseffective in a short time period. Therefore, we believe the bivariatenature of treatment outcome, whereby tumours are either completelyeradicated or grow unbounded, can be explained by heterogeneity inthis immune characteristic. Furthermore, the model highlights theapparent presence of negative feedback in the helper T cell and APCstimulation dynamics, when IL-12 and GM-CSF are co-expressed asopposed to individually expressed by the viral vector.
Project description:This phase I trial studies the side effects and best schedule of vaccine therapy with or without sirolimus in treating patients with cancer-testis antigen (NY-ESO-1) expressing solid tumors. Biological therapies, such as sirolimus, may stimulate the immune system in different ways and stop tumor cells from growing. Vaccines made from a person’s white blood cells mixed with tumor proteins may help the body build an effective immune response to kill tumor cells that express NY-ESO-1. Infusing the vaccine directly into a lymph node may cause a stronger immune response and kill more tumor cells. It is not yet known whether vaccine therapy works better when given with or without sirolimus in treating solid tumors.
