Filter by:A phase 2b, open label study to assess the safety and efficacy of increasing doses of pulsed, inhaled nitric oxide (iNO) in subjects with pulmonary fibrosis and sarcoidosis on long term oxygen therapy followed by a long term extension study
Sarcoidosis is a disease of unknown cause which affects adults of all ethnic backgrounds. Clumps of tissue called granulomas develop primarily in the lungs, but can damage other organs, especially the heart. Anecdotal evidence from autopsy studies suggests the heart is affected in up to 68% of patients, but there is much uncertainty about this figure. If undetected and untreated, it can lead to serious complications or even sudden death. The current recommendation is to perform heart tracings (ECG s) on all patients, but this detects fewer than half of those with heart involvement. Blood markers traditionally used to diagnose heart disease are unreliable, meaning there is no simple blood test in use. The investigators propose a study with three aims. Firstly, identify the true prevalence of heart disease by performing Magnetic Resonance Imaging (MRI) scans on a group of patients with newly diagnosed lung sarcoidosis. Those found to have heart disease will have specialist (but routine) electrical heart tests. Secondly, (and perhaps the most immediate and clinically relevant) to identify the best method of diagnosing heart involvement using a combination of three simple tests: advanced ECG, 24-hour continuous ECG and a new type of computerised ultrasound scan. Thirdly, to identify proteins in the blood that could be used to develop a simple blood test for heart involvement in patients with lung sarcoidosis.
This is a single centre exploratory study that aims to apply hyperpolarized xenon-129 (129Xe) magnetic resonance imaging (MRI) methods and measurements in individual patients with and without lung disease to better understand lung structure and function and evaluate response to therapy delivered as a part of clinical care.
This project focuses on the sub-group population with pulmonary sarcoidosis - a condition that causes red swollen tissue called granulomas to develop in organs such as the lungs. The condition is associated to symptoms of shortness of breath and a persistent dry cough. The aim of the research is to investigate the role of physical activity, exercise and diet within pulmonary sarcoidosis-related outcomes. Exercise has the potential to improve symptoms of pulmonary sarcoidosis including fatigue, dyspnoea, quality of life (QOL) and exercise tolerance. The use of exercise in symptomatic patients is supported by current evidence but is limited and requires further understanding, given the unique nature of the condition, in terms of physical and psychological outcomes. Specific dietary and exercise recommendations are limited by the lack of evidence for specific modifications such as the type(s), intensities, frequency and duration. The study will involve completion of validated questionnaires including quality of life (QOL; Sarcoidosis Health Questionnaire (SHQ) (see appendix III), the SHQ comprises of 29-item, 7 point Likert scale questionnaire and fatigue (Fatigue Assessment Scale; FAS (see appendix IV) and will require participants to attend two visits to the Kingston University, Human Performance Lab at Penrhyn Rd campus, this is to ensure reliability and validity for the data collected. The visits will consist of a range of physical tests including lung function, a six-minute walk test and muscle strength tests. The primary aim of the study is to ascertain the physical activity patterns in those with pulmonary sarcoidosis with regards to perceived physical activity, measured using the the International Physical Activity Questionnaires (IPAQ) (appendix V), which comprises of 27 items across five activity domains and actual physical activity ,measured by tri-axial accelerometry, fatigue assessment scale (appendix IV). The secondary aim of the study is to understand the effect of pulmonary sarcoidosis in relation to muscle strength and exercise capacity against physical activity, lung function and oxygen saturation and how these differ from healthy normative values. Participants will be asked to read the participant information and declare consent before starting the study. Only the researcher and supervisors of the study will have access to the raw data. Anonymity will be kept all times.
This is a multicenter, single-arm, unblinded/open-label study of the effect size of HRCT endpoints in response to glucocorticoid induction therapy in subjects with a diagnosis of pulmonary sarcoidosis who have not received glucocorticoid as initial sarcoidosis therapy (≥ 20 mg/day prednisone or prednisolone) or other sarcoidosis therapy for at least 3 months prior to enrollment. This study will enroll a total of approximately 24 subjects.
The purpose of this study is to find out if Acthar Gel is safe and effective to treat pulmonary sarcoidosis. Participants will be randomly assigned (like flipping a coin) to receive a shot under their skin of Acthar Gel or a matching placebo gel that has no drug in it. They will receive their assigned shot twice a week for 24 weeks. All participants who complete the 24-week treatment period will be eligible to receive Acthar Gel for 24 more weeks, even if they were originally in the placebo group.
Study comparing pirfenidone versus placebo for patients with advanced fibrotic sarcoidosis
Sarcoidosis is a multi-system granulomatous disorder that is triggered and influenced by gene-environment interactions. Although sarcoidosis predominantly affects the lungs in most cases, the clinical disease course is highly variable and any organ can be affected leading to end organ damage despite currently available therapeutics that unfortunately also have numerous and potentially devastating side effects. The environmental triggers of sarcoidosis are unknown but several occupational, environmental and infectious agents have been associated with sarcoidosis in susceptible hosts. Exposure to these triggers result in inflammation, characterized by activation of CD4+ T-cells, cytokine production, subsequent recruitment of other immune cells, and granuloma formation. Although several genetic markers have been associated with sarcoidosis, none fully explain individual susceptibility or clinical course variability, strongly implicating the environment and epigenetics. We have the ability to generate a map of the epigenetic histone modifications in immune cells via Chromatin Immuno-Precipitation coupled with next generation sequencing (ChIP-seq) and a map of transcriptome profiles via RNA-seq. The availability of histone and transcriptional signatures defining T cell activity in sarcoidosis will help identify the specific molecular programs affected by disease processes and can become the basis for future discovery of novel biomarker diagnostics in a clinical setting.
The goal of this study is to evaluate the diagnostic agreement between, on the one hand, ultra-low dose CT and MRI with UTE pulse sequences, and on the other hand, standard CT scan, to quantify lung parenchyma patterns in thoracic sarcoidosis.
The purpose of this study is to assess if ACZ885 will improve lung function in association with reduction of tissue inflammation in patients with chronic sarcoidosis.
