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

The purpose of this trial is to test a deescalated 3-fraction stereotactic body radiotherapy (SBRT) regimen to 45 Gray (Gy) in 3 fractions for centrally located thoracic tumors.

The purpose of the study is to evaluate the efficacy and safety of tiragolumab plus atezolizumab compared with placebo plus atezolizumab in participants with previously untreated locally advanced, unresectable or metastatic PD-L1-selected non-small cell lung cancer (NSCLC), with no epidermal growth factor receptor (EGFR) mutation or anaplastic lymphoma kinase (ALK) translocation. Eligible participants will be randomized in a 1:1 ratio to receive either tiragolumab plus atezolizumab or placebo plus atezolizumab.

The purpose of this study is to understand if treatment with one chemotherapy medication combined with immune therapy (pembrolizumab) is tolerable and effective for patients with lung cancer and performance status of 2 (PS2), which means you have limitations in carrying out certain activities or spend up to half of your day resting.

The general objective is to evaluate the effect of continuous positive airway pressure (CPAP) treatment in patients with masked hypertension. The secondary objectives are: i) To evaluate the prevalence of different circadian patterns of BP in ambulatory blood pressure monitoring (ABPM) (dipper / non-dipper); ii) To assess in these patients the relationship between compliance with CPAP treatment and the response to nocturnal BP; iii) To identify variables of the ABPM, and biomarkers that are related to the unfavourable pattern of nocturnal BP response in these patients treated with CPAP; iv) To evaluate the change in the profile of biomarkers with the treatment. Methodology: Open, parallel, prospective, randomized and controlled study in which an ABPM will be performed in individuals with masked hypertension referred to the sleep unit and diagnosed of OSA (AHI≥ 30) without sleepiness (Epworth≤18). A total of 64 subjects with OSA and masked hypertension will be recruited. It will be collected blood for the determination of biomarkers. Subsequently, they will be randomized to receive treatment with CPAP (32) or conservative treatment (32). After 3 months of initiation, ABPM and biological determinations will be repeated.

This pilot study is configured as a non-inferiority comparison of Performance Status 2 patients with Performance Status 0-1 patients, with the goal of demonstrating non-inferiority in terms of efficacy (progression-free survival, overall survival) and safety (rates of adverse events, quality of life) when treating Performance Status 2 patients with the same first-line immunotherapy-based regimen as Performance Status 0-1 patients.

Mepolizumab is a humanized monoclonal antibody (IgG1, kappa) that blocks interleukin- 5 (IL-5) thus inhibits production and survival of eosinophils. The aim of this phase 4, open-label, single-arm study is to evaluate the safety and efficacy of Mepolizumab 100 mg SC administered every 4 weeks in Indian participants aged 18 years or above with severe eosinophilic asthma. After the first dose of mepolizumab, participants will receive 5 more doses of mepolizumab at 4 weekly intervals. Following the last dose of mepolizumab, the end of the study Visit will occur 4 weeks later. During the treatment period, OCS use and dose adjustment in participants will be as per the investigator's discretion and clinical practice.

Currently international experts recommend therapeutic anticoagulation for veno-venous extracorporeal membrane oxygenation (VV-ECMO). Reports and case series suggest that the absence of therapeutic anticoagulation is safe for VV-ECMO. No randomized control trials have assessed this. The aim of this pilot study is to assess safety and feasibility of an "anticoagulation-free strategy" for veno-venous ECMO (VV-ECMO) in Acute respiratory distress syndrome (ARDS).

The goal of the study is to identify the maximum tolerated dose of endobronchial ultrasound-guided transbronchial injection (EBUS-TBNI) of cisplatin for Stage IV lung cancer.

COVID-19 patients who develop severe disease often develop acute respiratory distress syndrome (ARDS) as a result of a dysregulated immune response. This in turn stimulates a pro-inflammatory cascade ("cytokine storm") as well as emergency myelopoiesis. This proinflammatory cascade is activated when viral-mediated cell damage occurs in the lungs, resulting in the release of damage-signaling alarmin molecules such as S100A8/A9 (Calprotectin), HMGB1, Resistin, and oxidized phospholipids. These damage-associated molecular patterns (DAMPs) are recognized by the pattern recognition receptor Toll-Like Receptor 4 (TLR4) found on macrophages, dendritic cells and other innate immune cells and result in additional release of pro-inflammatory molecules. Several recent studies have shown that S100A8/A9 serum levels in hospitalized COVID-19 patients positively correlate with both neutrophil count and disease severity. Taken together the DAMP-TLR4 interaction forms a central axis in the innate immune system and is a key driver of the pathological inflammation observed in COVID-19. We hypothesis that targeting the initial step in the signalling pathways of these DAMPs in innate immunity offers the best hope for controlling the exaggerated host response to SARS-CoV-2 infection. EB05 has demonstrated safety in two clinical studies (>120 patients) and was able to block LPS-induced (TLR4 agonist) IL-6 release in humans. Given, this extensive body of evidence we believe EB05 could ameliorate ARDS due to COVID-19, significantly reducing ventilation rates and mortality.

Patients with pleural mesothelioma (PM) that cannot be surgically removed will receive standard chemotherapy (cisplatin or carboplatin and pemetrexed) given with durvalumab, a type of immunotherapy, or a treatment chosen by the study doctor, which is either standard chemotherapy or immunotherapy combination (ipilimumab and nivolumab). Durvalumab is an antibody (a type of human protein) that works by blocking a body substance called Programmed Death-Ligand 1 (PD-L1). Blocking PD-L1 helps the body's immune system attack cancer cells. Research has shown that durvalumab can slow tumor growth and shrink tumors in some people with cancer. Previous studies of combining durvalumab and chemotherapy showed that this combination is active in advanced mesothelioma. The purpose of this study is to see whether adding durvalumab to standard chemotherapy will improve overall survival (OS) in patients with PM.
