11 Clinical Trials for Various Conditions
Psoriasis is a chronic inflammatory disease that affects the skin and joints in 2-3 % of people in the United States. This inflammation of the skin, joints, and blood vessels in patients with psoriasis has been measured by older PET Scan technology but with limitations. With the new EXPLORER PET scanner technology, the investigators are testing to see if the EXPLORER is better than previous PET scanners and improve our ability to assess inflammation in patients. Also, it is known that the typical Western Diet - high in saturated fats, added sugars, and low in fiber - contributes to obesity and inflammation worldwide. There is evidence in animals that these signs of inflammation are reversible within 4 weeks when changed to a more balanced diet. Thus, this study aims to assess whether there are detectable decreases in inflammation of the skin and body of psoriasis patients who usually eat a Western Diet on an EXPLORER PET scan following 6 weeks of a more balanced diet.
The objective of this exploratory study is to gain an understanding of cutaneous and systemic inflammation and how restoration of the skin barrier through the use of moisturizer may restore the skin barrier function and reduce systemic inflammation in elderly humans compared to the young. The exploratory study will consist of three visits per subject. Subjects will be instructed to apply a moisturizer (Vanicream Moisturizing Skin Cream) over the entire skin surface from the neck down twice daily for up to 30 days.
Protocol Summary Constitutive STAT3 activity is implicated in many malignancies including Cutaneous T Cell Lymphoma. It is also essential for Th17 differentiation, a subset of CD4 effector T cell, implicated in chronic inflammatory conditions and possibly CTCL. HDAC inhibitors have shown activity in CTCL but their exact mechanism of action is not known. It is known that HDAC inhibitors regulate STAT3 transcriptional activity and hence can potentially be active in CTCL through modulation of the STAT3 pathway. The hypothesis is that Th17 cytokines contribute to the initiation of cancer by creating a pro-inflammatory microenvironment that predisposes cells to neoplastic transformation. To probe this, the investigators will compare the differences in cytokine production and gene expression in the skin resident T cells from patients with benign dermatoses and CTCL as well as in the blood/circulating lymphocytes of healthy donors and Sezary syndrome (SS). The investigators will also investigate whether HDAC inhibitors have a direct impact on the number of Th17 cells, the cytokine production by these cells and phosphorylated STAT3 protein in CTCL with subsequent treatment cycles. The objectives of this study are 1. Observe the epigenetic, transcriptional and phenotypic changes that take place in T cell during malignant transformation 2. Understand the mechanism of action of HDAC inhibitors in CTCL. Methods: Skin biopsy specimens from cutaneous T cell lymphoma (CTCL) patients and benign skin conditions namely eczema, dermatitis and psoriasis will be obtained through a standard punch biopsy procedure from the skin lesion. Additionally, 15 ml of peripheral blood from CTCL patients who have Sezary syndrome (SS) and from patients with benign skin condition will be collected. CTCL patients, who are starting treatment with HDAC Inhibitors namely Vorinostat and Romidepsin, will have a total of 3 skin biopsies and/or blood draws. The first procedure would be before starting treatment with either of these HDAC inhibitors. Two more skin biopsies and/or blood draws will be performed after first and second cycle of treatment. Levels of Th17 cytokines, IL-17, IL -22 and pSTAT3 protein will be determined by IHC staining in the skin and cytokine levels in the blood will be assayed by sandwich ELISA method.The investigators will also assay the mRNA levels of the transcription factors of the different T effector cells by qPCR.
Background: - Allergic inflammation is central to allergy-related diseases and disorders, such as asthma, food allergies, and atopic dermatitis. Atopic dermatitis, commonly called eczema is a chronic, noncontagious skin condition, usually starting in the first years of life, which causes itching and scaling of an individual s skin. Because atopic dermatitis is a common condition in children who have allergy-related diseases, including asthma, researchers are interested in studying both individuals with atopic dermatitis and their close relatives (parents and children) to better understand how allergy-related diseases develop and progress. In addition, some patients with inherited disorders with features including atopic dermatitis or other aspects of allergy such as food allergy, asthma, hay fever, hives, and others, will also be seen. Objectives: - To study the natural history of diseases of allergic inflammation, such as atopic dermatitis or genetic disorders associated with allergic inflammation. Eligibility: * Children and adolescents between 1 month and 21 years of age who have a documented history of moderate to severe atopic dermatitis. * Individuals between 1 month and 80 years of age who have a suspected genetic or inherited allergy disorder related to atopic dermatitis or allergic pathways. * Child and adult relatives of eligible participants will also be studied on this protocol. Design: * The study will require one initial visit to the National Institutes of Health Clinical Center (lasting 1-5 days), as well as any required follow-up visits for treatment and research studies. Participants will receive treatment for atopic dermatitis and other allergic diseases as part of the study for up to 1 year. * Participants will have some or all of the following tests as part of this study: * A detailed physical examination and medical history * Allergy skin prick testing to examine participants' responses to different allergens. * Blood samples for additional allergen testing, testing the immune system, and other research purposes * Skin punch biopsy to take a skin sample * Lung function tests to measure airflow from the lungs and inflammation * Food-related tests to diagnose potential food allergies * Leukapheresis to collect white blood cells only * Research samples, including stool specimens, saliva samples, buccal swabs (to collect cells from the inside of the cheek), and skin cell samples * Clinical digital photography to provide images of affected and healthy skin. * Participants will be asked to return for follow-up visits and tests for up to 1 year after the initial visit(s)....
This phase II trial studies the effect of zanubrutinib and CAR T-cell therapy in treating patients with aggressive B-cell non-Hodgkin's lymphoma or transformed indolent B-cell lymphoma that has come back (recurrent) or does not respond to treatment (refractory). Zanubrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. T cells are infection fighting blood cells that can kill tumor cells. The T cells given in this study will come from the patient and will have a new gene put in them that makes them able to recognize CAR, a protein on the surface of cancer cells. These CAR-specific T cells may help the body's immune system identify and kill cancer cells. Giving zanubrutinib together with CAR T-cell therapy may kill more cancer cells.
UMPALA is a research study to look at the effect of four different, approved contraceptives on the cervical and vaginal tissues as well as on factors in the blood. Participants will have a baseline examination then receive one of four approved, marketed contraceptive products. Cervico-vaginal assessments will take place 4 weeks after contraceptive initiation and 3 months after to assess changes in mucosal safety after use of various contraceptive products in young, healthy, HIV uninfected women.
This phase II trial tests the effectiveness of golcadomide and rituximab as bridging treatment before chimeric antigen receptor (CAR) T-cell therapy in patients with aggressive B-cell non-Hodgkin lymphoma that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Patients that are able to receive CAR T-cell therapy have a potential for cure, however, many will not be qualified to receive therapy due to relapse. Bridging therapy is therapy intended to transition a patient from one therapy or medication to another or maintain their health or status until they are a candidate for a therapy or have decided on a therapy. Golcadomide may help block the formation, growth or spread of cancer cells. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Giving golcadomide and rituximab as bridging therapy before CAR T-cell therapy may kill more tumor cells and may improve the chance of proceeding to CAR T-cell therapy in patients with relapsed or refractory aggressive B-cell non-Hodgkin lymphoma.
This phase II trial tests the safety, side effects, and best dose of TTI-621 (closed to enrollment) or TTI-622 in combination with pembrolizumab in treating patients with diffuse large B-cell lymphoma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). TTI-621 and TTI-622 are called fusion proteins. A fusion protein includes two specialized proteins that are joined together. In TTI-621 and TTI-622, one of the proteins binds with other proteins found on the surface of certain cells that are part of the immune system. The other protein targets and blocks a protein called CD47. CD47 is present on cancer cells and is used by those cells to hide from the body's immune system. By blocking CD47, TTI-621 and TTI-622 may help the immune system find and destroy cancer cells. Pembrolizumab is a monoclonal antibody directed against human cell surface receptor PD-1 (programmed death-1 or programmed cell death-1) that works by helping the body\'s immune system attack the cancer and may interfere with the ability of cancer cells to grow and spread. Giving TTI-621 (closed to enrollment) or TTI-622 in combination with pembrolizumab may kill more cancer cells in patients with relapsed or refractory diffuse large B-cell lymphoma.
This phase II/III trial compares the side effects and activity of oral azacitidine in combination with the standard drug therapy (reduced dose rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone \[R-miniCHOP\]) versus R-miniCHOP alone in treating patients 75 years or older with newly diagnosed diffuse large B cell lymphoma. R-miniCHOP includes a monoclonal antibody (a type of protein), called rituximab, which attaches to the lymphoma cells and may help the immune system kill these cells. R-miniCHOP also includes prednisone which is an anti-inflammatory medication and a combination of 3 chemotherapy drugs, cyclophosphamide, doxorubicin, and vincristine. These 3 chemotherapy drugs, as well as oral azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Combining oral azacitidine with R-miniCHOP may shrink the cancer or extend the time without disease symptoms coming back or extend patient's survival when compared to R-miniCHOP alone.
This phase II trial studies how well nivolumab with or without varlilumab works in treating patients with aggressive B-cell lymphomas that have come back (recurrent) or do not respond to treatment (refractory). Immunotherapy with monoclonal antibodies, such as varlilumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
