Filter by:The primary purpose of the study is to evaluate the efficacy of brensocatib at 10 and 40 milligrams (mg) once daily (QD) compared with placebo in improving clinical symptoms of CRSsNP.
The aim of this study is to evaluate the effect of the primary endoscopic frontal sinus surgery on the clinical outcome in patients having moderate to severe eosinophilic chronic rhinosinusitis with polyps with primary outcome measures in form of recurrence of polyp using endoscopic polyp score and Secondary outcome measures include Lund MacKay score, SNOT-22 and need for corticosteroid to control polyp postoperatively.
This study seeks to explore the mechanism through which dupilumab improves olfactory cleft inflammation in patients with chronic sinusitis with nasal polyps (CRSwNP). The investigators expect this study to provide convincing evidence that dupilumab improves clinical olfaction via direct reduction in olfactory cleft inflammation.
The goal of this randomized clinical trial is to compare the effects of two newly available biological drugs for the treatment of severe chronic rhinosinusitis with nasal polyps in Danish patients. The main questions it aims to answer are whether the two drugs are comparable in effect after 24 weeks in terms of: - A subjective score (the SNOT-22) - An objective score, i.e.the physician-assessed score of nasal polyp size (the Nasal Polyp Score (0-8)) Methods: Participants will be randomized into two groups and receive either drug in the standard dose. After 24 weeks the effect is assessed. If the clinical effect is sufficient in terms of the criteria set by the Danish Medicinal Council (see elsewhere), treatment continues with the same drug for an additional 24 weeks. If the effect criteria are not met, the subject crosses-over to the opposite drug for an additional 24 weeks. After 48 weeks the effect is assessed once more.
This study is a pragmatic, real-life, observational study recruiting adult patients with chronic rhinosinusitis with nasal polyposis who are eligible to start biologicals as standard treatment. The aim of this study is to observe the long-term outcomes of biologicals in CRSwNP patients with or without comorbid asthma in 'real life'. Moreover, the investigators will gain insight into the mechanisms of biologicals in the local and systemic immunity of these patients and investigate novel local and systemic biomarkers and predictors of response.
The investigators propose a real-world study to assess the mechanism of action of long-lasting response to mepolizumab in patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) and identify clinically useful predictors of response. Mepolizumab is a monoclonal antibody targeting IL-5 and is approved for use in asthma and CRSwNP. In clinical studies, 12 months of treatment with mepolizumab improved signs and symptoms of CRSwNP and reduced the need for surgery. While several biologic medications targeting facets of the Type 2 mechanism are currently indicated for chronic rhinosinusitis with nasal polyps mepolizumab alone appears capable of modifying the disease's biological behaviour and producing long-standing improvements after the cessation of treatment. In the mepolizumab for CRSwNP regulatory trial (SYNAPSE), a subset of patients experienced dramatic and long-lasting, which is over 48 months after cessation of administration of the investigational medicinal product (IMP) in our experience. This has been partially captured in a follow-on study to the registration trail, which showed that a subset of patients followed for 24 weeks after cessation of biologic therapy (with continued use of mometasone furoate) demonstrated persistent improvements over baseline. However, the mechanism of the long-lasting effect in a subset of patients is not well understood, and it is impossible currently to identify patients who will derive this maximal benefit. The mechanism for the prolonged improvements in CRSwNP seen in certain patients with mepolizumab remains to be established but suggests that effects beyond eosinophil trafficking are implicated. The investigators believe that mepolizumab has IL-5-mediated pleiotropic effects which contribute to disease modification with effects extending beyond eosinophil activation and trafficking. This may include the following primary or secondary effects: i) Improving epithelial barrier function ii) Altering mast cell dynamics iii) Reversing epigenetic modifications iv) Altering the immune response to better clear pathogenic bacteria or viruses.
The goal of this laboratory study is the examine the effect of mepolizumab drug on the health and function of the cells lining the human nasal airways in vitro cell culture derived from patients with chronic rhinosinusitis with nasal polyposis. The main questions the study aims to study are: 1. To see what mepolizumab does to suppress inflammation of the human cells. 2. To see what mepolizumab does to maintain barrier integrity of epithelial cells
It is a first in human (FIH) study to evaluate safety, and potential efficacy of Airiver Nasal DCB in the treatment of recurrent CRSwNP or CRSsNP. Participants will receive AIRIVER Nasal drug-coated balloon treatment.
This is a multi-center, randomized, double blind, placebo-controlled study to evaluate the efficacy, safety, PK, PD and immumogenicity of GR1802 injection in comparison to placebo in addition to a background treatment of mometasone furcate nasal spray (MFNS) in patients with chronic rhinosinusitis with nasal polyposis (CRSwNP). Patients will receive GR1802 injection or Placebo every 2 Weeks.
The goal of this observational study is to learn about the agreement between sensors analyzing algorithm and body plethysmography in measuring oral and nasal breathing in healthy adults, and in patients with chronic rhinosinusitis, asthma and chronic obstructive pulmonary disease. The main question it aims to answer is: • Is the algorithm-based method accurate enough in analyzing respiratory obstruction as compared to body plethysmography (reference method)? Participants will perform a short breathing protocol (oral and nasal breathing with different masks) during which time their breathing is monitored with both methods.
