Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

A Randomised, Double-Blind, Parallel-Group, Placebo-Controlled 28-week Phase 3 Efficacy and Safety Study of Tezepelumab in Reducing Oral Corticosteroid Use in Adults with Oral Corticosteroid Dependent Asthma

Recent advances have been made in prevention of the viral infection via vaccines but there is still need for effective treatment options for patients. Novel therapies need to be developed to further improve clinical outcomes. The biggest medical challenge in the response to COVID-19 is ARDS requiring hospitalization in an intensive care setting and ventilator dependence. Intravenously administered umbilical cord derived exosomes and stem cells have been reported in literature to alleviate pulmonary distress in such patients. The purpose of this study is to explore the safety and benefits of intravenous administration of WJPure and EVPure in the treatment of COVID-19 patients with moderate to severe ARDS. .

Olfactory dysfunction is a defining symptom of COVID-19 infection. Studies have demonstrated improved olfaction in patients with post infectious olfactory dysfunction after an olfactory training (OT). The aim of this study is to assess the clinical outcomes of olfactory training (12 weeks) therapy in the treatment of persistent olfactory dysfunctions after COVID-19. Specially, we aim to compare the effectiveness of two different olfactory training (different odors) with a placebo group. A group will train themselves with 4 scents (rose, orange, clove and eucalyptus) and another group with 4 different scents (cheese, coffee, strawberries and lemon). The placebo group will train themselves with an odorless substance. Olfaction sensory evaluation will be performed by using different olfaction tests (Sniffin' Sticks and UPSIT) and complete questionnaires to assess olfactory perception and particularly parosmia and phantosmia.

This is a randomized, assessor-blind, placebo controlled, multicenter, clinical endpoint bioequivalence study to compare the efficacy and safety of generic fluticasone propionate inhalation aerosol USP 44 mcg (Glenmark Pharmaceuticals Ltd) to Flovent HFA (fluticasone propionate inhalation aerosol) 44 mcg (GSK group of companies) in treatment of patients with bronchial asthma.

This proof-of-concept study is designed to evaluate whether a pedagogic technique used to help performers, known as the Complete Vocal Technique (CVT), can be used to help patients with a type of voice disorder known as Muscle Tension Dysphonia (MTD). MTD is responsible for up to 40% of patients presenting with voice and throat complaints. MTD is due to inefficient or ineffective voice production resulting from an imbalance in the control of the breathing mechanism, and uncontrolled constriction of the muscles in the larynx (voice box) or vocal tract (throat space above the vocal cords). Standard treatment is Voice Therapy delivered by a specialist Speech Therapist (SLT-V) often using a video link (telepractice aka telehealth). CVT is widely used in Europe by singers and vocal coaches. Practitioners (CVT- Ps) undergo a three-year accredited training programme, and the systematic and structured approach helps healthy singers and other performers optimise the function of the voice to produce any sound required. It also helps if the performer has vocal problems, which are also mainly due to uncontrolled throat constrictions. The purpose of this pilot study is to see if the CVT voice therapy approach (CVT-VT) can help, and offers advantages, to standard SLT-V methods in the treatment of patients with MTD. Ten adult patients will be recruited from the Voice clinic at Nottingham University Hospital. Participants will have a multidimensional assessment using questionnaires, and voice recordings and then receive up to 6 video sessions of CVT-VT delivered using a video link by a CVT-P. The participants will then be reviewed back in clinic at 8 weeks and be reassessed, using further questionnaires and analysis of the voice pre- and post-therapy recordings, to evaluate the outcome of this treatment approach. Qualitative methodology will determine whether CVT-VT offers any therapeutic advantages to existing SLT-VT treatment methods.

Different studies have suggested that COPD is associated with elevated alveolar NO and increased expression of NOS2 in alveolar walls, small airway epithelium and vascular smooth muscle. Furthermore, arginase activity in COPD is shown to correlate inversely with total NO metabolite in sputum and with pre- and post- bronchodilator FEV1; at the same time ADMA levels in serum is shown to be correlated with airway resistance and ADMA in COPD airways was documented to be able to shift the L-arginine metabolism towards the arginase pathway. As demonstrated in a guinea model, the arginase inhibition can shift the L-ornitine:L-citrulline ratio towards L-citrulline, preventing neutrophilia, mucus hypersecretion and collagen synthesis. Thus, increasing substrate availability for NOS by arginase inhibition or supplementation of L-arginine or L-citrulline or a combination thereof, may represent a window of opportunity in patients with COPD. Our study was constructed in order to investigate as a primary objective whether in symptomatic patients with COPD, daily bioarginine on top of chronic inhaled therapy can improve respiratory symptoms and dyspnea during daily life activities. The secondary objective of this study is to determine whether there is any correlation between improvement in respiratory symptoms and distance walked at the 6MWT and lung function parameters. In order to do so, we designed a multi center, interventional, prospective, randomized, controlled vs placebo, proof of concept study: COPD patients will be randomized to receive BioArginine twice daily on top of chronic inhaled therapy or to continue their chronic Inhaled therapy plus placebo for 6 weeks. In order to evaluate the impact on respiratory symptoms and dyspnea the CRQ (Chronic Respiratory disease Questionnaire) and the LCADL (London Chest Activities of daily Living) Scale, as well as the 6MWT, will be used.

This study is a Phase I/II open-label, multi-center study to evaluate the safety, tolerability, PK, and an anti-tumor activity of JIN-A02, a 4th generation EGFR-TKI agent for oral administration, in EGFR mutant-positive, advanced NSCLC subjects who showed disease progression after receiving standard anticancer therapy, including approved EGFR-TKI therapy and/or no more than a single platinum-based anticancer chemotherapy. In Part A of the study, dose escalation is carried out where MTD is evaluated using Bayesian Optimal Interval (BOIN) design in subjects with advanced NSCLC harboring EGFR-mutation of C797S or T790M. In Part B, dose exploration is carried out to further evaluate the safety of JIN-A02 and to determine the RP2D using 2 preliminary effective dose levels and with the help of a safety review committee (SRC) in advanced NSCLC subjects harboring EGFR mutant C797S or T790M. In Part C dose expansion study, subjects with EGFR mutant who show disease progression after receiving standard anticancer therapy, including approved EGFR-TKI therapy with activity against T790M such as Osimertinib and/or no more than one platinum-based anticancer chemotherapy, are divided into 5 different cohorts based on the EGFR mutation and the anti-tumor activity of JIN-A02 is evaluated. Before enrollment in the study, the EGFR mutant profile is determined using either tumor tissue and/or plasma ctDNA. The profile is determined locally through a test method approved by the sponsor. The sponsor reviews and approves each potential subject for enrollment. Study eligibility evaluation will utilize local test(s).

This study is being done to understand body's response to hybrid home-based and on-site rehabilitation program utilizing individually tailored exercises throughout a total of 18 sessions with 12 of them occurring onsite, in people with and without chronic respiratory diseases, such as Chronic Obstructive Pulmonary Disease (COPD) and Obstructive Sleep Apnea (OSA) and in individuals recovered from COVID-19. Exercise training programs vary widely for people with COPD, OSA, and during prolonged recovery from COVID infection. This study will help identify if this program is helpful to address muscle loss and fatigue specifically in populations with and without chronic respiratory diseases.

We conduct this study to investigate the efficacy of triple therapy (high-dose glucocorticoids + cyclophosphamide + calcineurin inhibitor) compared with dual-therapy regimens (high-dose glucocorticoids + cyclophosphamide/calcineurin inhibitor) and whether it reduces the risk of poor pulmonary prognosis in patients with moderate to high risk anti-MDA5+ DM.

350 participants will be enrolled in this study. The target population are patients newly diagnosed with OSA and starting CPAP treatment. User accessible customizable comfort settings (Response setting, expiratory pressure relief (EPR) on/off and EPR level, and Ramp) will be set to either default (control group), or personalized for that participant (active treatment group). Usage will be recorded for the first 1 month of CPAP treatment, to determine if customizing comfort settings can improve CPAP compliance
