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

Pre-clinical and clinical studies have shown that low-dose radiation therapy has good immune regulatory effects, activates different anti-tumor immune pathways, and regulates tumor stroma to better promote T cell infiltration. Conventional fractionated radiotherapy increases antigen release and presentation, and stimulates immune cells. In theory, the combination of the two can reverse immune resistance. Our study aims to clarify the efficacy and safety of low-dose radiotherapy combined with conventional fractionated radiotherapy in reversing immune therapy resistance for patients with non-small cell lung cancer, including objective response rate (ORR), progression free survival time (PFS), disease control rate (DCR), health-related quality of life assessment (HRQoL), and incidence of adverse events (AEs).

In this study, the investigators hypothesize that the reference product (SalbR/Ventolin) is more effective than SalbG (Salbutamol Sandoz) at improving the lung function in children with asthma, and that this difference increases alongside the severity of the airway resistance. (Null hypothesis: There is no difference). This could be explained by different properties and deposition of the aerosol. Purpose of this research: Rejecting the null hypothesis. This is based on the answers to the questions below. Research questions: Is there a difference between the increase in FEV1 (and FVC) after 100 μg SalbG versus FEV1 after 100 μg SalbR in children aged 4-14 years with insufficient asthma control? (primary question) Is there a difference in the subjective feeling of the children after inhalation with 100 μg SalbR and after 100 μg SalbG, measured with a VAS score? Is the increase in FEV1 (and FVC) in children with asthma between 4-14 years of age with insufficient asthma control after inhalation of 400 μg SalbR different than after inhalation of 400 μg SalbG? Is there a difference in the subjective feeling of the children after inhalation with 400 μg SalbR and after 400 μg SalbG, measured with a VAS score?

Introduction: Respiratory diseases are associated with high rate of morbidity and mortality in Brazil. Cardiopulmonary rehabilitation through respiratory muscle training, aerobic training and strengthening of upper and lower limbs emerges as one of the resources available for the treatment and monitoring of patients with respiratory diseases. To add in this perspective, the application of HD-tDCS induces significant neurophysiological and clinical effects in several body systems. Objective: To identify the chronic effects of non-invasive neurostimulation associated with the rehabilitation of patients with respiratory disorders. Material and methods: This is a pilot study, quantitative, clinical trial type, randomized and controlled, double blind. The sample will be composed by patients with respiratory diseases, aged above 18 years old. The study will consist of two groups: (1) HD-tDCS will be applied - anodic current + respiratory rehabilitation with respiratory muscle training (RMT) and (2) Sham - Only respiratory rehabilitation with RMT without any type of cortical stimulation. The chronic effects of neurostimulation by HD-tDCS associated with cardiopulmonary rehabilitation, with TMR, during 12 sessions will be evaluated. Patients will be evaluated, before and after the protocol, in relation to cortical activation function, pulmonary function, subjective perception of effort, respiratory muscle function, functional capacity, sensation of dyspnea and quality of life. For statistical analysis, intention-to-treat analysis will be used and groups will be compared using Student's t-test, for continuous variables, or chi-square, for categorical variables. ANOVA split-plot, repeated measures for primary outcomes. Analyzes of covariance to identify differences between groups using baseline scores as covariates. Effect sizes and confidence intervals will be calculated using eta squared (η²). Expected results: Neurostimulation would enhance the effects of respiratory rehabilitation and reduce the symptoms of patients with these diseases.

The study is being conducted to evaluate the efficacy, and safety of SHR-1905 injection in subjects with chronic rhinosinusitis with nasal polyps (CRSwNP), as well as to explore the reasonable dosage of SHR-1905 injection for CRSwNP.

This is an Open-label, multicenter clinical study conducted in two Phases to establish the efficacy, safety, tolerability, and pharmacokinetics of the ataxia telangiectasia mutated and Rad3-related protein kinase (ATR) inhibitor M1774 in Combination with Cemiplimab in Participants with Non-Squamous Non-Small Cell Lung Cancer (nsqNSCLC) that has Progressed on Prior Anti-PD-(L)1 and Platinum-based Therapies

This is a multi-center, single-arm, open-label, Phase II clinical trial which explores the safety and efficacy of TGRX-326 in patients with ALK-positive advanced NSCLC who have failed prior 2nd-generation ALK treatments due to progressive disease or intolerance.

Chronic obstructive pulmonary disease (COPD) is a common, preventable and treatable disease. The aim of prospective randomized study is to evaluate the effects of TCM Daoyin training on Individuals at-risk for COPD.

A study to investigate efficacy and safety of ceralasertib plus durvalumab in participants aged ≥ 18 years with advanced or metastatic non-small cell lung cancer whose disease progressed on or after prior anti-PD-(L)1 therapy and platinum-based chemotherapy.

This study will treat patients with advanced NSCLC who have progressed following prior therapy in order to assess the effect of DZD9008 on exposure of midazolam, digoxin and rosuvastatin, through multiple PK parameters, when administrated as a single dose alone and in combination with DZD9008. Also, it will assess the safety and tolerability of DZD9008 in the presence and absence of co-administration of cocktail probes.

Idiopathic Pulmonary Fibrosis (IPF): It is a progressive and fatal fibrosing interstitial lung disease of unknown etiology, with a median survival of only 2 to 3 years. Epidemiology of IPF (with reference to the international epidemiological studies due to the lack of accurate epidemiological data in China): the incidence was 2 to 30 per 100,000 person years, and the prevalence was 10 to 60 per 100,000. More males suffer from IPF than females. In population aged more than 65 years, the estimated prevalence was up to 400 per 100,000. Medications for IPF: Currently there is no medication with definitely significant efficacy (such as slowing down the disease progression). However, the following drugs can be used as appropriate based on the results of randomized and controlled clinical trials conducted in recent years and taking account of the patients' actual clinical conditions. Pirfenidone: It has been proven to remarkably slow down forced vital capacity (FVC) decline and reduce the risk of death to a certain degree, with the side effects of photosensitivity, asthenia, rash, stomach upset, and anorexia. Pirfenidone is recommended for IPF patients accompanying with mild to moderate pulmonary dysfunction in clinical practice. Nintedanib: It could remarkably slow down the absolute value of FVC decline in IPF patients, thereby slowing down the disease progression to a certain degree. The most common adverse reaction of Nintedanib is diarrhoea. Future therapeutic strategies for IPF: A multi-drug concomitant therapy against different therapeutic targets for pulmonary fibrosis may be a potential strategy, among which, the research and development of anti-fibrotic drugs may be most valuable in treatment of this disease, with promising potentials of halting or reversing disease progression, extending the life expectancy, improving the quality of life, and reducing the side effects.
