Filter by:PEP03 is a new chemical entity developed as a highly selective, potent, and orally active 5-LO inhibitor. PEP03 exerts its action by blocking the generation of both cysteinyl LTs and LTB4. These LTs have been associated with the inflammatory response in the lung and with the clinical sequelae, including bronchospasm. Preclinical pharmacological in- vitro, ex-vivo and in-vivo testing indicates that PEP03 has multiple beneficial actions including prevention of bronchoconstriction, and reduction of vascular leakage, cellular infiltration, and bronchial hyperresponsiveness. Clinical studies in asthmatic patients indicate that PEP03 improved FEV1 and other secondary endpoints, such as morning and evening peak flow, daytime and nighttime symptoms score, beta-agonist use, physician’s and patient’s global impression of change. Since leukotrienes have been suggested to be involved in the pathophysiology of COPD, this study is designed to explore the clinical utility of PEP03 for the treatment of moderate COPD.6; 7; 8; 9
A breathing condition known as "chronic obstructive pulmonary disease" (COPD) caused by cigarette smoking is a major health problem. The way by which smoking leads to lung disease is uncertain. Recent research done in animals provides a description of specific changes (that is a reduction) in these immune cell types as a result of cigarette smoke exposure. The study you have been asked to participate in is a pilot study to see if similar changes occur in humans who smoke. The purpose of this study is to evaluate this new method of testing blood in 3 groups of 10 people: normal non-smoking subjects, subjects who smoke with no history of lung disease and subjects who smoke and have smoking related COPD.
The aims of this study are to investigate the association between sputum and plasma levels of nociceptin and substance P with cough severity and airway hyperreactivity in patients with asthma, COPD and chronic cough.
Large population-based studies suggest that patients with chronic obstructive pulmonary disease (COPD) are 2 to 3 times at risk for cardiovascular mortality, which accounts for a large proportion of the total number of deaths. How COPD increases the risk of poor cardiovascular outcomes is largely unknown. However, there is growing evidence that persistent low-grade systemic inflammation is present in COPD and that this may contribute to the pathogenesis of atherosclerosis and cardiovascular disease among COPD patients. Inflammation and more specifically, C-reactive protein (CRP), has been linked with all stages of atherosclerosis, including plaque genesis, rupture and subsequent thrombo-fibrosis of vulnerable vessels. Recently, our group has demonstrated in a relatively small study that short-term inhaled corticosteroid (ICS) therapy can repress serum CRP levels in stable COPD patients. Conversely, withdrawal of ICS leads to a marked increase in serum CRP levels. Although very promising, these data cannot be considered definitive because the study was small in size and scope (N=41 patients). Additionally, this study did not address the potential effects of combination therapy with ICS and long-acting β2 agonists (LABA). This is an important short-coming because combination therapy of ICS and LABA have been shown to produce improved clinical outcomes over ICS monotherapy and is commonly used by clinicians in the treatment of moderate to severe COPD. We hypothesize that inhaled fluticasone (Flovent®) reduces systemic inflammation and that combination therapy (Advair®) is more effective than steroids alone in reducing systemic inflammation in COPD. In this proposal, we will implement a randomized controlled trial to determine whether ICS by themselves or in combination with LABAs can: 1. reduce CRP levels in stable COPD patients and 2. reduce other pro-inflammatory cytokines, which have been linked with cardiovascular morbidity and mortality such as interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1)
