Project description:<p>LGL leukemia can be divided into three subsets including the following: αβ or γδT-LGL and NK-LGL leukemia. All three subtypes will be enrolled using a two-stage design. The primary endpoint of the study is assessment of overall clinical response. Correlative laboratory studies will be performed aimed at determining the mechanism of response to treatment. Thirteen participants will be accrued in the first stage at a dose of 300 mg BID administered intermittently every other week (i.e., 7 days on and 7 days off). If there are two or more responders, the protocol will be extended to a second stage of the study and accrual will be extended to 25 evaluable participants. Allowing for 10% rate of ineligibility due to unexpected events and dropout, we will accrue 14 patients in the first stage and 27 patients in total. Participants that withdraw from the study for reason unrelated to toxicity, will be replaced. There are two potential stopping rules for toxicity.</p> <p>If 3 or more participants out of the 13 enrolled in the first stage experiences grade IV neurotoxicity, the study will be stopped due to excessive toxicity. Dose reductions have been incorporated for hematologic toxicity. Treatment of T and NK LGL leukemia with immunosuppressive agents such as low-dose methotrexate generally require from four to six months for a clinical response and sometimes much longer. Therefore, in participants who show clinical improvement with less than grade three toxicity, tipifarnib treatment will be continued for as many as four additional months (12 months total). After the first 8 months, response will be assessed. The protocol treatment will be discontinued in participants with progression of disease. A long-term follow up will be performed for five years in patients that receive a complete clinical response. The long-term follow up will consist of vital signs, weight, CBCs, serum chemistries, and physical examination at six month intervals.</p>

Project description:Retinoids have been used as potential chemotherapeutic or chemo-preventive agents because of their differentiation, anti-proliferative, pro-apoptotic, and anti-oxidant effects. We investigated the effect of all trans- retinoic acid (ATRA) at different stages of the neoplastic transformation using an in vitro model of breast cancer progression. This model was previously developed by treating the human normal-like breast epithelial MCF-10F cells with high dose of estradiol and consist of five cell lines which shown a progressive neoplastic transformation: MCF-10F (normal stage), trMCF (premalignant stage), bsMCF (invasive stage) and caMCF (tumorigenic stage). In 3D-cultures, MCF-10F cells form tubules resembling the normal mammary gland although after treatment with high doses of estradiol, trMCF cells, formed tubules and, spherical masses which are an indication of cell transformation. By ring cloning, trMCF clone 11 which only formed spherical masses in collagen was isolated. Our results showed that the early transformed trMCF clone 11 cells shown a reduction of spherical masses and increased of tubules in collagen after being treated with 10-5M (10M-BM-5M) and 10-6M (1M-BM-5M) ATRA; the number of tubules was higher in cells treated with 10-6M ATRA (43% vs. 10% tubules). The invasive bsMCF and tumorigenic caMCF cells did not shown any changes in morphology after ATRA treatment. Analysis of expression studies in early transformed cells treated with 10-6M ATRA showed that 271 probes upregulated in trMCF clone 11 cells were downregulated after ATRA treatment and, 316 probes that were downregulated were upregulated after ATRA treatment in these cells to similar levels than the normal breast epithelial cells MCF-10F. These genes were involved in the aryl hydrocarbon receptor signaling, RAR Activation, xenobiotic metabolisms signaling, molecular mechanisms of cancer and cell morphology. Our results shown that ATRA was able to re-differentiate transformed cells at early stages of the neoplastic process suggesting that ATRA could potentially be used to inhibit the progression of premalignant lesions of the breast such as ductal carcinoma in situ (DCIS). We investigated the effect of all trans- retinoic acid (ATRA) at different stages of the neoplastic transformation using an in vitro model of breast cancer progression. This model was previously developed by treating the human normal-like breast epithelial MCF-10F cells with high dose of estradiol and consist of five cell lines which shown a progressive neoplastic transformation: MCF-10F (normal stage), trMCF (premalignant stage), bsMCF (invasive stage) and caMCF (tumorigenic stage).

Project description:Anti-TNF (tumor necrosis factor) monoclonal antibodies have revolutionized management of Inflammatory bowel disease. Their common features include high efficacy but also immunogenicity and increased infection risk. Since 2013, two generics or biosimilars of the first anti-TNF have been registered in Europe, which long lerm safety profile needs yet to be established.
This prospective, multicenter, observational cohort study will assess safety of treatment of anti-TNF monoclonal antibodies in inflammatory bowel disease patients in Poland.
Eligible are consecutive patients in whom anti-TNF is started for Crohn’s disease, ulcerative colitis or indeterminate colitis between January 1st, 2014 and December 31st, 2015. Data to be collected include demography, Montreal classification, indication to treatment, previous treatment, operations, extraintestinal manifestations and concomitant diseases. Data on response, tolerability and safety of anti-TNF and on concomitant treatment will be collected. Adverse events logs will be completed. Majority of IBD centres in Poland, pediatric and adult, academic and regional, have agreed to participate in the study.
As a result of the study, the frequency of adverse events in a cohort of Polish IBD patients on various anti-TNFs will be established.

Project description:Monoclonal antibody-based immunotherapy is now considered to be a main component of cancer therapy, alongside surgery, radiation, and chemotherapy. Monoclonal antibodies possess a diverse set of clinically relevant mechanisms of action. In addition, antibodies can directly target tumor cells while simultaneously promoting the induction of long-lasting anti-tumor immune responses. The multifaceted properties of antibodies as a therapeutic platform have led to the development of new cancer treatment strategies that will have major impacts on cancer care. This review focuses on the known mechanisms of action, current clinical applications for the treatment of cancer, and mechanisms of resistance of monoclonal antibody therapy. We further discuss how monoclonal antibody-based strategies have moved towards enhancing anti-tumor immune responses by targeting immune cells instead of tumor antigens as well as some of the current combination therapies.

Project description:The metzincin clan of metalloproteinases includes the MMP, disintegrin and metalloproteinase (ADAM) and ADAM with thrombospondin motifs families, which cleave extracellular targets in a wide range of (patho)physiological processes. Antibodies constitute a powerful tool to modulate the activity of these enzymes for both therapeutic and research purposes. In this review, we give an overview of monoclonal antibodies (mAbs) that have been tested in preclinical disease models, human trials and important studies of metzincin structure and function. Initial attempts to develop therapeutic small molecule inhibitors against MMPs were hampered by structural similarities between metzincin active sites and, consequently, off-target effects. Therefore, more recently, mAbs have been developed that do not bind to the active site but bind to surface-exposed loops that are poorly conserved in closely related family members. Inhibition of protease activity by these mAbs occurs through a variety of mechanisms, including (i) barring access to the active site, (ii) disruption of exosite binding, and (iii) prevention of protease activation. These different modes of inhibition are discussed in the context of the antibodies' potency, selectivity and, importantly, the effects in models of disease and clinical trials. In addition, various innovative strategies that were used to generate anti-metzincin mAbs are discussed. LINKED ARTICLES: This article is part of a themed section on Translating the Matrix.

Project description:Over the last 30 years the role of monoclonal antibodies in therapeutics has increased enormously, revolutionizing treatment in most medical specialties, including neurology. Monoclonal antibodies are key therapeutic agents for several neurological conditions with diverse pathophysiological mechanisms, including multiple sclerosis, migraines and neuromuscular disease. In addition, a great number of monoclonal antibodies against several targets are being investigated for many more neurological diseases, which reflects our advances in understanding the pathogenesis of these diseases. Untangling the molecular mechanisms of disease allows monoclonal antibodies to block disease pathways accurately and efficiently with exceptional target specificity, minimizing non-specific effects. On the other hand, accumulating experience shows that monoclonal antibodies may carry class-specific and target-associated risks. This article provides an overview of different types of monoclonal antibodies and their characteristics and reviews monoclonal antibodies currently in use or under development for neurological disease.

Project description:CD24 is a potential oncogene reported to be overexpressed in a large variety of human malignancies. We have shown that CD24 is overexpressed in 90% of colorectal tumors at a fairly early stage in the multistep process of carcinogenesis. Anti-CD24 monoclonal antibodies (mAb) induce a significant growth inhibition in colorectal and pancreatic cancer cell lines that express the protein. This study is designed to investigate further the effects of CD24 down-regulation using mAb or small interfering RNA in vitro and in vivo. Western blot analysis showed that anti-CD24 mAb induced CD24 protein down-regulation through lysosomal degradation. mAb augmented growth inhibition in combination with five classic chemotherapies. Xenograft models in vivo showed that tumor growth was significantly reduced in mAb-treated mice. Similarly, stable growth inhibition of cancer cell lines was achieved by down-regulation of CD24 expression using short hairpin RNA (shRNA). The produced clones proliferated more slowly, reached lower saturation densities, and showed impaired motility. Most importantly, down-regulation of CD24 retarded tumorigenicity of human cancer cell lines in nude mice. Microarray analysis revealed a similar pattern of gene expression alterations when cells were subjected to anti-CD24 mAb or shRNA. Genes in the Ras pathway, mitogenactivated protein kinase, or BCL-2 family and others of oncogenic association were frequently down-regulated. As a putative new oncogene that is overexpressed in gastrointestinal malignancies early in the carcinogenesis process, CD24 is a potential target for early intervention in the prevention and treatment of cancer.
