This is a single-arm extension study to investigate the long-term safety, tolerability, and efficacy of lunsekimig in adult participants with inadequately controlled CRSwNP who have completed a previous lunsekimig CRSwNP clinical study (also referred to as the parent study ACT18207). The study duration will be up to approximately 56 weeks per participant, 52 weeks of treatment period, and 4 weeks of follow-up.
NCT06516302
The goal of this clinical trial is to learn if GR1802 works to treat severe chronic rhinosinusitis with nasal polyps (CRSwNP) in adults. It will also learn about the safety of GR1802. The main questions it aims to answer are: 1. Does GR1802 reduce the need for surgery and systemic corticosteroid use？ 2. What medical problems do participants have when taking GR1802? Researchers will compare GR1802 to a placebo (a look-alike substance that contains no drug) to see if GR1802 works to treat CRSwNP. Participants will: Take GR1802 or a placebo once every 2 weeks for 13months. Visit the clinic once every 2 weeks for checkups and tests. Keep a diary of their symptoms and the dosage and number of times they use mometasone furoate nasal spray.

A Multicentre, Randomised, Double-Blind, Parallel-Group, Placebo-Controlled Phase 3 Efficacy and Safety Study of Tezepelumab in Participants with Severe Chronic Rhinosinusitis with Nasal Polyposis
NCT05246267
The central hypothesis of this study is that the addition of dupilumab treatment onto standard-of-care intranasal corticosteroids will improve patient-reported measures of disease activity and sense of smell in a cohort of mostly ethnical and racial minority patients with CRSwNP
NCT07316959
This randomized controlled trial evaluated the effectiveness of long-term, low-dose clarithromycin (250 mg/day) in reducing symptoms, improving endoscopic and radiologic scores, and preventing early recurrence of nasal polyps after endoscopic sinus surgery. Conducted at the ENT Department of Sir Ganga Ram Hospital, Lahore, the study included patients aged 15-75 undergoing surgery for nasal polyps. Group A received clarithromycin for three months in addition to standard therapy, while Group B received standard therapy alone. Patients treated with clarithromycin showed significantly greater improvements in SNOT, Lund-Kennedy, and Lund-Mackay scores at 8 and 12 weeks compared to controls (p\<0.05). Polyp recurrence at three months was also lower in the macrolide group (12%) than in the non-macrolide group (32%). Overall, low-dose clarithromycin was found to be safe and effective in enhancing postoperative outcomes and reducing early recurrence of nasal polyps after endoscopic sinus surgery.
NCT07125586
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common condition causing nasal congestion, discharge, and reduced sense of smell, seriously affecting patients' quality of life. A subtype called eosinophilic CRSwNP (eCRSwNP) is difficult to treat and often recurs after surgery. Currently, diagnosing this subtype requires tissue samples after surgery, which delays treatment decisions and may lead to unnecessary surgeries. Our research team has developed a new, non-invasive diagnostic system using advanced spectral technology to detect a natural fluorescence marker inside eosinophils (a type of immune cell) in nasal polyps. This system can quickly identify eCRSwNP before surgery by shining a safe light on the nasal tissue and analyzing the fluorescence signals. This study aims to evaluate how accurate and safe this real-time diagnostic system is in clinical practice. If successful, it will help doctors choose better personalized treatments, reduce unnecessary surgeries, lower recurrence rates, and ultimately improve patients' lives.

NCT06118554
Three-dimensional (3D) printing has been an emerging technology with uses in a wide array of fields. This research aims to use 3D printing as a tool to provide personalized education to maximize treatment efficacy based on the patient's individual anatomy. With increased irrigation to the sinuses, we hypothesize there will be improved patient satisfaction and higher quality of life. The outcomes of this research could lead to a new option for patients who live with chronic rhinosinusitis are not candidates for surgery or are interested in less invasive options. The 3D printed nasal replica is not something that would be implanted, rather it is a hand-held device used specifically for participants to better understand their nasal anatomy.
NCT04147013
This is a proposed randomized prospective study to evaluate both the anti-inflammatory and analgesic effects of a COX-2 inhibitor, celecoxib, in patients with aspirin-exacerbated respiratory disease and Chronic rhinosinusitis following endoscopic sinus surgery. The investigators hypothesize that supplementation with celecoxib can potentially improve surgical outcomes and reduce the postoperative usage of opioid analgesics without an increased risk of bleeding or asthma exacerbation
NCT05708300
Mepolizumab is a biologic agent already approved for severe asthma. Recently, there is increasing evidence concerning the benefit of anti-IL5 treatments upon patients with nasal polyposis with or without severe asthma. The novelty of this project is that no biologic agent has yet been fully investigated to identify any biomarkers of response for patients with nasal polyps with or without asthma including sinonasal tissue remodeling a key element in the resultant histopathological changes of the inflammation. The investigation of airway remodeling of various locations (nose and bronchus) under mepolizumab treatment will be our primary objective on the long-term basis of 156 weeks of treatment. Endobronchial and nasal biopsies will be performed as routine care for tissue evauation and disease investigation for every patient. Besides, the united airways will provide better guidance for medical treatment of chronic rhinosinusitis (CRS) patients with nasal polyps (CRSwNP) and asthma. The initial idea is based on investigating the characteristics that could predict the effectiveness of mepolizumab on patients with nasal polyposis with or without asthma. Patients will receive 39 doses of mepolizumab for 156 weeks. An additional aim of this study is to identify characteristics of non-responders and responders to mepolizumab. Responders will be identified based on airway remodeling status, biomarkers in tissue and secretion samples and on the reduction of the need of surgery through Lund-Kennedy endoscopic score, Lund-Mackay score and patient's clinical status in the 6th, 12th and 36th month after the initiation of treatment. Regarding the unified airway system, nose and pharyngeal microbiome will be evaluated before and after 52 weeks of mepolizumab treatment in patients with nasal polyps whereas in patients with nasal polyps and asthma bronchus microbiome will also be evaluated. Lung samples will help gain information about the inflammatory profile and local microbiome of CRSwNP patients with asthma through molecular and cellular assays. The human Pharyngeal Microbiome might play a protective role in Respiratory Tract Infections and it has been reported that the microbiome provides critical signals to promote maturation of immune cells and differentiation of the tissue. Thus, we will make an effort to correlate microbiome of various locations with clinical and laboratory characteristics of responders and non-responders to mepolizumab treatment.

Chronic rhinosinusitis (CRS) is a multifactorial disease characterized by persistent symptomatic inflammation of the mucosa of the nose and paranasal sinuses, with (CRSwNP) or without (CRSsNP) the presence of nasal polyps. It affects 5 to 12% of the general population. CRS is often associated with asthma, which has a prevalence of 4% in the general population, reaching 30%-70% among patients with CRS. The current standard clinical evaluation of patients for both diseases has two main components: a subjective one (self-assessment provided by the patient), based mainly on the PROMs (Patient-Reported Outcome Measures) questionnaire, and an objective one (formulated by the clinician). Questionnaires present accuracy and response rate problems that have been investigated in the literature, finding that short questionnaires, incentives, personalization of questionnaires as well as repeat sending strategies or telephone reminders have a beneficial impact on the quantity and quality of responses. Today there are many new channels provided by technology. Among them, AI chatbots have been used in a variety of healthcare domains such as medical consultations, disease diagnosis, mental health support and, more recently, risk communications for the COVID-19 pandemic, and can offer a better way to collect questionnaires. At the same time, the recent technical solution of new non-invasive techniques for RFID radio frequency identification devices allows subjective reports to be accompanied with objective reports. The PRECISION project aims to evaluate systems for home monitoring of chronic rhinosinusitis (CRS) and asthma, two highly prevalent chronic diseases. The frequent association between the two pathological conditions is a further argument in support of the rationality of a common approach. As regards the collection of PROMs, three acquisition channels will be compared: i) AI Chatbots; ii) PhoneBot; iii) Mobile application. Data will be analyzed in relation to patient profiles to define the quality and quality of response. Regarding objective evaluation, the project will investigate the efficiency of objective remote airflow measurements for both upper (CRS) and lower (asthma) airways using dedicated non-invasive systems based on RFID technology.
NCT03725956
Nasal polyposis (NP) is a chronic inflammatory disease of the nasal and sinus mucosa leading to protrusion of edematous polyps in the nasal cavity. Prevalence of NP among the chronic rhinosinusitis patients is 25-30 %. NP leads to significant limitations in physical, emotional and social aspects of life of the affected patients. Sleep disorder is frequently reported by those patients with impaired nasal breathing. Till now few studies have objectively assessed the impact of NP on sleep quality. the objectives are to figure out sleep disturbances in NP and to analyze the outcomes of sinus surgery on sleep recovering.
NCT05843019
The purpose of this study is to investigate the relationship between long-term use of systemic steroids in patients with upper and lower respiratory tract diseases and their own production of cortisol (cross-sectional), as well as whether those with low cortisol levels have an impact on bone density. As patients with CRSwNP have a high use of steroids, they routinely undergo a DEXA scan at the Respiratory Clinic, Department of Ear-Nose-Throat Surgery and Audiology (ENT) - Rigshospitalet (RH) to examine whether their bone density and structure are affected. The scan will be included as a clinical secondary outcome to assess whether systemic steroid use has an impact on this. The purpose of the study is therefore to compare steroid intake, baseline P-cortisol, the body's response to ACTH (measured by cortisol levels after the test), and bone density in patients with chronic sinusitis (CRS) with and without asthma in an unselected population at the Respiratory Clinic (cross-sectional). In addition, at the 4-month follow-up (exploratory follow-up, pilot project), it will be investigated whether good adherence (\>80%) to inhalation therapy (nasal steroid and lung steroid) and additional treatment with biologicals has a negative effect on the body's own production of P-cortisol.
NCT04104594
Impaired olfaction is one of the major complaints of patients with nasosinus polyposis, with nasal obstruction. In case of failure of medical treatment for patients with polyposis nasosinusal, they may use endoscopic surgery nasosinusal. Before surgery, 73% are hyposmic or anosmic, compared to 43% after surgery. Persistence of hyposmia or anosmia despite the removal of polyps can be explained by mechanisms inflammatory in the mucous membrane of the olfactory cleft. In addition, studies in mice have shown a degeneration of primary olfactory neurons at the level of the olfactory mucosa in connection with directly with TNF alpha, a pro-inflammatory molecule.
