Active clinical trials for "Respiration Disorders"

The main purpose of the study is to see how safe GSK1995057 is and how well it is tolerated after dosing. The study will also investigate how GSK1995057 is taken up, metabolised (chemically broken down), distributed through the body and excreted, and what some of the effects of the study drug are.

Vaccines work by stimulating the body to produce a high-quality, rapid and specific immune response upon exposure to infection by a particular disease-causing microorganism - the microorganism targeted by the vaccine. Evidence is emerging that some vaccines may have additional 'non-specific effects' (NSEs); that is, effects on the immune system beyond the direct protection against the diseases for which the vaccines were developed. It has been proposed that rabies vaccine has protective NSEs in people and animals, with receipt of rabies vaccine in children associated with a reduced risk of meningitis and cerebral malaria in one study, and a history of rabies vaccination in free-roaming dogs associated with increased survival rates in another study. Studies in mice have shown that prior rabies vaccination protects against bacterial sepsis. The biological mechanism of action of any such NSE of rabies vaccine is unknown. Other vaccines with reported protective NSEs (e.g. bacillus Calmette-Guerin vaccine against tuberculosis, a disease caused by Mycobacterium tuberculosis) have been show to reprogram the immune system, leading to enhanced protection against infection with disease-causing microorganisms unrelated to M. tuberculosis. In this study, we will test the hypothesis that rabies vaccine has non-specific protective effects against common infectious disease (CID) syndromes (upper respiratory illness, diarrhea and fever) in a population of veterinary students. We will randomly assign previously-unvaccinated students who volunteer for the study to receive a primary course of three injections of rabies vaccine (experimental group) or an identical course of three injections of sterile water (control group). Participants will not know to which group they have been assigned. We will ask all participants to report episodes of illness through an online survey each week for 26 weeks, and will also record all clinically- and laboratory-confirmed cases of illness with CID syndromes. We hypothesize that rates of self-reported new episodes of CID illness over 26 weeks will be at least 25% lower in the experimental group, relative to the control group.

The purpose of this long-term follow-up of a Phase I study is to evaluate the kinetics of the antibody response to NTHi-Mcat antigens and long-term safety, in subjects aged between 50-71 years at the time of enrolment in the NTHi-Mcat-001 study. These subjects were previously exposed to two adjuvanted formulations of the NTHi-Mcat vaccine administered according to a 0, 2 months schedule in the NTHi-Mcat-001 (201281) study. The subjects that had received saline placebo controls will also be included in this follow-up study to make comparisons with the investigational vaccines. No vaccinations will be administered in this trial.

To evaluate the compatibility and correlation between noninvasive surface respiratory electromyography and invasive transesophageal diaphragmatic electromyography measurements, as facilitating indicators of neural respiratory drive evaluation during treadmill exercise. Transesophageal diaphragmatic EMG (EMGdi,es) and surface inspiratory EMG, including surface diaphragmatic EMG (EMGdi,sur), surface parasternal intercostal muscle EMG (EMGpara) and surface sternocleidomastoid EMG (EMGsc) were detected simultaneously during increasing capacity exercise in stable patients with COPD. EMGdi,es, EMGdi,sur, EMGpara and EMGsc was quantified using root mean square (RMS), which represent as RMSdi,es, RMSdi,sur, RMSpara and RMSsc.

Cigarette smoking is the leading cause of preventable death in Switzerland. Cigarette smoking eventually kills one in two smokers, mostly through cancer, heart disease and respiratory failure. Recently, electronic nicotine delivery systems (ENDS; also called vaporizer or electronic cigarette) have become popular with smokers who want to stop smoking or reduce their exposure to inhaled chemicals since ENDS use appears to be safer than tobacco smoking. Studies suggest that ENDS use improves health outcomes, such as reducing respiratory symptoms, and presents only minimal respiratory risks, such as mild throat irritation and dry cough. In a prospective 6-month randomized, controlled trial evaluating smoking reduction/abstinence in 300 smokers not intending to quit experimenting two different nicotine strengths of a e-cigarette model compared to its non-nicotine choice, respiratory symptoms similarly improved in all three study groups. One study compared the short-term effects of cigarette smoking to ENDS use and found that cigarette smoking led to an acute reduction in lung function, which was not observed with ENDS. Findings on short-term airway resistance is conflicting. Short term increase in resistance in ENDS users might be caused by aerosolizing the liquid, and not by the same substances that harm lung function in cigarette smokers. Smokers who shifted from tobacco cigarettes to ENDS have offered anecdotes of dramatically improved lung function, but animal models suggest that ENDS liquids can increase markers of asthma. No large randomized trials have tested the effect of ENDS on respiratory symptoms. For this trial, cigarette smokers motivated to quit smoking cigarettes will be included. Participants in the intervention group will receive an ENDS and nicotine-containing e-liquids, which they will be allowed to use ad libitum. Additionally, they will receive smoking cessation counseling. Participants in the control group will receive smoking cessation counseling only. All participants will be followed over a 24-months period. Respiratory symptoms such as chronic obstructive pulmonary disease (COPD), asthma and dyspnea will be assessed by means of questionnaires at baseline and at 6-, 12- and 24-months follow up. This trial will provide useful data on changes in respiratory symptoms in a large sample of participants.

The two-part phases will each have a unique patient population, The goal in this application is to see if that carotid bodies are "offline" is correct and to determine whether a cohort of SARS-Cov-2 patients can be identified who fit this profile and would be suitable for drug treatment. The testing will require one group of subjects to hold their breaths for a short period while the investigators monitor vital signs and blood O2 levels. A second group of "healthier" COVID subjects will be asked perform a walk-test inside their rooms for six minutes while vital signs are monitored as well as blood O2 levels. If the subjects are in the healthy control group, they will perform the walk test in a designated hallway at the medical center also while there vitals are being monitored. The goal, using a mild stimulus, is to determine whether respiration increases if blood O2 saturation is decreased. If it does not, that would indicate a failure of the carotid body oxygen sensing system.

Phase IIb clinical trial to assess the Immunogenicity and Safety of a HIPRA's Candidate Booster vaccination (PHH-1V) in adults fully vaccinated with the adenovirus vaccine Vaxevria against COVID-19.

Preoperative dexamethasone reduces symptoms after different surgical procedures including mastectomy in breast cancer, but the effect in the postoperative respiratory function remains unknown. The aim of this protocol was to determine if the administration of a single dose of dexamethasone during the preoperative, could improve respiratory function and postoperative symptoms of patients undergoing mastectomy in breast cancer.

The purpose of this study is to evaluate the safety, reactogenicity and immunogenicity of GSK Biologicals' NTHi candidate vaccine in adults, administered for the first time in humans.

The purpose of this study is to assess the safety, reactogenicity and immunogenicity of 8 different formulations of investigational NTHI vaccine in current and former smokers, 50-70 years of age.
