Filter by:Atopic dermatitis (AD) is a chronic and recurrent inflammatory disease, prevalent between 1 and 20% in the world population, with a predominance of childhood, but which may be present in adult life. AD results from a complex interaction between genetic and environmental factors, with the presence of a defect in the skin barrier and deregulation of the immune response, culminating in an inflammatory response in the skin predominantly type 2. Disease control is based on restoring skin hydration, smoothing itching and controlling the process specific sensitizing agents such as inhalant allergens and foods that may pathogenesis of the disease. In selected patients who present IgE mediated response to inhalant allergens, allergen-specific immunotherapy can be effective. Classically, the subcutaneous route is the most used, however, sublingual immunotherapy (SLIT) has been used in increasing form. There are still few studies on the efficacy and safety of SLIT in atopic dermatitis. Therefore, the present study aims to to investigate the role of SLIT in the management of patients with AD allergic mites, through a randomized, double-blind and placebo-controlled study
Patients with refractory and/or recurrent neuroblastoma have poor prognosis despite complex multimodel therapy and therefore, novel approaches are urgently needed. The investigators are attempt to treat this disease using T cells genetically modified with a 4th generation lentiviral chimeric antigen receptor (CAR) targeting GD2 (4SCAR-GD2). The 4SCAR-GD2-modified T cells can recognize and kill neuroblastoma through the recognition of GD2, a surface protein expressed at high levels on neuroblastoma but not on normal tissues. This study will evaluate the side effects and effective doses of 4SCAR-GD2 T cells in treating refractory and/or recurrent neuroblastoma.
The prognosis of advanced metastatic melanoma remains poor although a breakthrough has been achieved with the novel anti-CTLA-4 treatment (ipilimumab) for a subset of patients. Unfortunately, due to immune resistance, the majority of patients do not obtain long-lasting clinical benefit. Radiotherapy is able to interfere with immune resistance by inducing immunogenic cell death. Preclinical evidence indicates that combining radiotherapy with anti-CTLA-4 treatment increases response rates compared to single agent treatment. These data are supported by several spectacular clinical cases and one retrospective study. The investigators hypothesize that combining ipilimumab with radiotherapy will result in a higher response rate compared to ipilimumab or radiotherapy in monotherapy. Given the complexity of the interaction in anti-tumor immunity, the first goal of this project is to assess the safety of the combined treatment.
The purpose of this study is to evaluate safety of the triple COG schema with the monoclonal antibody Dinutuximab + cytokines (GM-CSF and IL2) and isotretinoin (13-cis-retinoic acid, or RA) in patients with high-risk neuroblastoma.
To evaluate the tolerability and safety of ADXS11-001 (1 x 10^10 colony forming units [cfu]) administered with prophylactic premedication in repeating 3-dose study cycles in women with persistent, metastatic, or recurrent squamous and non-squamous carcinoma, adenosquamous, or adenocarcinoma of the cervix. To evaluate tumor response and progression-free survival (PFS, time to progression) by immune-related Response Evaluation Criteria in Solid Tumors (irRECIST).
The primary objective of this study is to evaluate the safety and tolerability of multiple sub-cutaneous injections of GeniusVac-Mel4, a dendritic cell-based cancer vaccine, in patients with melanoma. The secondary objectives are to determine immune response and clinical efficacy of such injections in patients with melanoma.
The purpose of this study is to evaluate the safety and the efficacy of combined treatment strategy of WT1ASCI, infusion of ex vivo regulatory T cells depleted T lymphocytes and in vivo regulatory T cells depletion as post-consolidation therapy in patients with WT1-positive Acute Myeloid Leukemia. The study will also evaluate the clinical activity and immune response of this approach in bad risk patients in CR1 and all patients in CR2 or CR3, non eligible for an allogeneic Hematopoietic Stem Cell Transplantation
Grass pollen and house dust mites (HDM) are the most common allergens causing allergic rhino-conjunctivitis (RC) and/or asthma (A). Subcutaneous allergen specific immunotherapy (SCIT) reduces symptoms and use of medication. The purpose of SABAL is to assess the effect of SCIT on disease severity classifications in terms of number of days affected- and sick days on patients with grass pollen and/or HDM induced disease. These outcome measures will be gathered in one single measure: Quality Adjusted Life Years (QALY)
Background: - Visceral leishmaniasis (VL) is an infection caused by parasites carried by sand flies. The parasites cause fever, weight loss, and enlargement of the spleen and liver. They can also affect the blood and immune system. One possible treatment for VL involves an experimental drug called SCH708980, which may help to prevent the immune system from becoming suppressed and worsening the VL. Researchers want to give the drug along with AmBisome(Registered Trademark), which kills the parasites, to see if it is a safe and effective treatment. Objectives: - To study the safety and effectiveness of SCH708980, alone and combined with AmBisome(Registered Trademark), as a treatment for visceral leishmaniasis. Eligibility: - Individuals 18 to 60 years of who have been diagnosed with visceral leishmaniasis in the past 4 to 5 days, are HIV-negative, and are willing to stay in the hospital for 30 days. - All participants will come from and be treated at the Kala-Azar Medical Research Center in Muzaffarpur, India. Design: - This is a two-part study. Participants will be assigned to only one part of the study. - Participants will be screened with a medical history and physical exam; blood, urine, and stool samples, spleen or bone marrow samples; spleen measurements; a chest xray; and a heart function test. - Part 1 participants will be separated into two groups: a larger group will have a selected dose of the study drug followed by AmBisome 7 days later, and a smaller group will have a placebo treatment followed by AmBisome. - Part 2 participants will have either the study drug or a placebo plus AmBisome, based on the test results from the Part 1 participants. - All participants will be monitored in the hospital for 30 days, and will have the following tests: - Regular blood samples - Urine and stool samples (day 14) - Spleen measurements (days 8, 14, 21, and 30) - Spleen or bone marrow sample (day 30 only). Participants who still have VL symptoms will give another sample on day 45. - At 6 months after the start of treatment, participants will have a follow-up visit with spleen measurements, blood and stool samples, and possible spleen or bone marrow samples
While allergen specific immunotherapy (SIT) is highly effective for allergic diseases in children, the underlying immunological mechanisms are unclear. Regulatory T (Treg) cells may be crucial in induction of tolerance. Our aim was to investigate the role of CD4+CD25+Foxp3+ T cells and IL-10-secreting type I T regulatory (Tr1) cells in the response to one year of cluster SIT to Dermatophagoides pteronyssinus for allergic rhinitis in children. CD4+CD25+Foxp3+regulatory T cells and IL-10-secreting type I T regulatory (Tr1) cells were analyzed in children allergic to Dermatophagoides pteronyssinus during one year cluster specific immunotherapy (SIT) in a prospective and randomized study. Peripheral blood mononuclear cells (PBMCs) were collected from 25 children receiving SIT and 21 receiving pharmacotherapy. The frequencies of CD4+CD25+Foxp3+ T cells and allergen-specific IL-10+IL-4-, IFN-γ+IL-4-, IL-4+IFN-γ-CD4+ T cells were measured by flow cytometry. Production of IL-4, IFN-r, and IL-10 in supernatants from allergen-stimulated PBMC culture was measured by ELISA. Finally, the suppressive effect of CD4+CD25highTreg cells from both groups was estimated.
