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

Multicenter investigation featuring an open-label lead-in followed by a double blinded, randomized, placebo-controlled Phase 2/3 part to evaluate the safety and efficacy of MultiStem therapy in subjects with moderate to severe Acute Respiratory Distress Syndrome (ARDS) due to pathogens including COVID-19.

The study is being conducted to evaluate the efficacy, safety and tolerability of famitinib combined with HS-10296 in subjects with advanced EGFR-mutant NSCLC.

Patients with obese late onset (after childhood) asthma can have lower FeNO levels, yet be highly symptomatic and poorly responsive to inhaled steroids. This is a common asthma phenotype, particularly among females. This reduction of NO occurs through increased arginase activity and uncoupling of NO synthase (NOS), by accumulation of asymmetric di-methyl arginine (ADMA), which further lowers the L-arginine/ADMA ratio, preferentially promoting reactive oxygen species (ROS) formation and inflammation at the expense of NO. Indeed, in patients with obese late onset asthma, lower L-arginine/ADMA plasma ratios are associated with reduced FeNO, increased bronchial hyperreactivity, and greater asthma morbidity. In our pilot studies, the administration of L-citrulline, as an L-arginine donor, to patients with obese late onset asthma increased the L-arginine/ADMA ratio, FeNO levels, and improved asthma control and lung function. Therefore, the objectives of the protocol are to: a) determine the efficacy of L-citrulline, as an add-on treatment to improve the asthma control and lung function in obese late onset asthmatics; b) leverage the use of asthmatic and control cells to further understand obesity-related changes in epithelial airway NO metabolism, and how these changes relate to bronchoconstriction and lung function, c) determine airway epithelial changes in mitochondrial function and bioenergetics in obese late onset asthmatics and how these are modified by L-citrulline. To do this, 54 obese late onset asthmatics with suboptimal control will be blindly randomized, in a cross over study, comparing 15g/day of L-citrulline vs. placebo, in two 8-week treatment periods with a 6-week washout in between. The co-primary study outcomes are asthma control (ACQ, ACT) and FeNO, and secondary endpoints plasma L-arginine/ADMA, FEV1 and PC20 methacholine. Parallel to this study, a small study of 10 healthy obese controls will receive open label L-citrulline for 7 weeks to establish comparative reference values for the study aims. During the initial treatment phase, 50% of study participants will be randomly allocated to undergo pre and post L-citrulline treatment bronchoscopy to obtain BAL and airway epithelial cells. The research group proposing this study is highly experience in asthma clinical trials, implementation of cross over design studies, and in the use of research bronchoscopies.

This is a Randomized, Double-Blind, Placebo-Controlled, Multicenter, Phase III Study to evaluate the efficacy and safety of Toripalimab injection (JS001) or placebo combined with chemotherapy in Advanced Non-small Cell Lung Cancer (NSCLC) Participants with TKI-resistant EGFR-mutated Tumors; and evaluate the population with the best predictive biomarkers, i.e., positive diagnosis population. About 440 subjects with advanced non-small cell lung cancer with activated EGFR mutation will be 1:1 randomized into two groups, JS001 combined with the standard 1st-line chemotherapy will be given in the study group whereas placebo combined with standard 1st-line chemotherapy will be given in the control group. The stratification will be based on the following factors: The history of the previous lines of EGFR-TKI treament ( 1st or 2nd generation of TKI vs. 3rd generation of TKI vs. 1st or 2nd generation of TKI + 3rd generation of TKI) ; Disease stage (IIIB-C vs. IV);

A placebo-controlled, multicenter, randomized trial to test GKT137831 in ambulatory patients with idiopathic pulmonary fibrosis. This drug is an inhibitor of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX) isoforms. The investigators hypothesize the drug will decrease pulmonary injury due to reactive oxygen species (ROS) generated by NOX enzymes, which are believed to play an important role in the development of IPF. Treatment with GKT137831 could result in significant benefit for a lung disease that has, until now, been almost invariably inexorable. This clinical trial represents the bedside application of a series of NOX translational and basic studies and discoveries, over several years, from the laboratory of Dr. Victor Thannickal.

This is a randomized, multicenter, double-blind placebo-controlled phase 3 study of efficacy and safety of BCD-100 in combination with pemetrexed+cisplatin/carboplatin compared to placebo in combination with pemetrexed+cisplatin/carboplatin in subjects with previously untreated metastatic non-squamous NSCLC. The main hypothesis of the study is that BCD-100 in combination with chemotherapy prolongs OS compared to placebo with chemotherapy.

The principal objective is to evaluate the effect of CPAP treatment on blood pressure (BP) in normotensive patients with dipper circadian pattern with sleep apnea-hypopnea syndrome (SAHS). The secondary objectives are: i) To evaluate the prevalence of the different circadian patterns of BP in ambulatory blood pressure monitoring (ABPM) ii) To establish the relationship between CPAP compliance and BP response; iii) Identify which ABPM variables and biomarkers are related to BP response; iv) Evaluate changes in the biomarkers' profile with the CPAP treatment. Methodology: Open-label, parallel, prospective, randomized and controlled trial including normotensive patients diagnosed with severe SAHS without significant somnolence. 64 patients with dipper circadian pattern will be included and will be randomized to receive CPAP (32) or conservative treatment (32). ABPM and blood sample collection will be performed at the beginning of the study and at 3 months.

The fibrotic interstitial lung diseases (fILD) are characterised by lung scarring, distressing breathlessness and poor health-related quality of life. Exertional desaturation (low blood oxygen during exercise) is a hallmark of fILD, occurring in over 50% of patients. It is sometimes treated with ambulatory oxygen therapy (AOT), which involves breathing supplemental oxygen during physical activity. However the absence of clinical trials has given rise to marked variations in policy and practice globally. Even where AOT is available, treatment adherence using the traditional delivery method of cylinder gas is poor. Recently new devices called portable oxygen concentrators (POCs), have become available, which are lighter and more maneuverable than a cylinder. This may enhance adherence and maximize treatment benefits. This trial will determine the clinical benefits and societal costs of AOT for people with fILD and exertional desaturation. A randomised controlled trial with blinding of participants, assessors and clinicians, and an embedded economic evaluation will be conducted. A total of 260 participants with fILD and exertional desaturation will be randomly assigned to use either AOT or air delivered using a POC for 6 months. If this trial demonstrates clinical and economic benefits of AOT then the findings can be rapidly translated into practice.

This trial will compare the effectiveness of two common surgical practices for Type C esophageal atresia repair: esophageal atresia (EA) with distal tracheoesophageal fistula (TEF). Infants with EA/TEF requiring surgical intervention will be recruited. Subjects will be randomized to either repair with or without transanstomotic tube (TT) during esophageal anastomosis creation. Primary outcome is symptomatic anastomotic stricture development requiring dilation within 12 months.

This is a prospective, randomized, single clinical study designed to evaluate its safety and efficacy by using Microwave Ablation combine with Pembrolizumab in patients with Stage ⅢB-Ⅳ Non-small Cell Lung.Cancer (NSCLC) who failed with first-line therapy.
