Filter by:Background: Allergic fungal rhinosinusitis (AFRS) is a severe type of sinus infection. People with AFRS develop heavy mucus and growths called polyps that apply pressure to the sinuses and block their breathing. Surgery can remove the polyps, but they often grow back. Researchers want to test an approved drug they believe may help people with AFRS. Objective: To test a drug (Dupilumab) in people with AFRS. Eligibility: People aged 18 years or older with suspected AFRS who are scheduled to undergo surgery for nasal polyps. Design: Participants will have several tests before their surgery. They will have imaging scans of their sinuses. They will have an endoscopic exam: A tube with a camera and a light will be inserted into their sinuses. They may give blood and mucus samples. They will have standard treatment with nasal sprays for 2 to 6 weeks before their surgery. Excess nasal tissue removed during the surgery will be collected for research. Then they will begin treatment with the study drug. Dupilumab is injected under the skin. Some participants will receive the study drug. Some will receive a placebo injections. The placebo injections are just like the study drug but contain no medicine. Participants will not know which injections they are getting. All participants will administer the injections to themselves at home. They will do this every 2 weeks for 1 year after the surgery. They will have a clinic visit 16 weeks after surgery. Participants will have follow-up for 12 weeks after treatment ends.
The investigators aim to investigate two major so far unresolved topics in CRSwNP research: (1) Thorough functional and molecular characterisation of barrier function in patients suffering from CRSsNP and CRSwNP and (2) effect of dupilumab treatment on barrier function in polyp patients. This will be achieved in patient-derived samples by employing measurement of barrier function in primary cell cultures in combination with a mass cytometry based imaging approach, transcriptomic analysis as well as cytokine and microbiome data of individual patients.
This is a multicentre, non-interventional, single arm study that aims to describe the treatment patterns in France: patients' characteristics, disease characteristics, prior treatments for Severe chronic rhinosinusitis with nasal polyposis and treatment prescription modalities. As well as to assess the clinical outcome after initiation of dupilumab (Dupixent®) and safety of the product during the two years of treatment
Nasal sinus polyposis is a chronic inflammatory pathology of the nasal cavity and sinus cavities that causes bilateral and multifocal polyp development and has a prevalence of 2 to 4% in the general population. Therapeutic management consists of first-line medical treatment for anti-inflammatory purposes. Local corticosteroid therapy, using nasal sprays, is the background treatment. Surgical management is offered to patients in case of failure of medical treatment. Although effective, surgery does not protect patients from recurrence of symptoms related to regrowth of polyps. Recently, biologics have appeared, which despite its effectiveness, about 20% of patients have a partial or no response to these treatments. There is currently no possibility of determining the probability of response to treatments in patients. It is therefore essential to determine an anatomo-clinico-biological correlation associating the anatomopathological profile, the clinical characteristics and the cytokine signature in order to best guide the patient's management, including the initiation of biotherapy. Indeed, patients, according to their clinical, biological characteristics and the cytokine signature of their polyps will react differently to different treatments, including surgery and biotherapy. This correlation will serve as a predictor of treatment response.
The main purpose of this study is to evaluate the efficacy and safety of lebrikizumab in adult participants with chronic rhinosinusitis and nasal polyps treated with intranasal corticosteroids. The study will last about 18 months.
The primary purpose of this study is to assess the effect of verekitug (UPB-101) on the endoscopically determined size and extend of nasal polyps in participants with chronic rhinosinusitis with nasal polyps (CRSwNP) and to assess the safety and tolerability of verekitug (UPB-101) compared to placebo.
During this project, the investigators want to explore in vitro changes in basal cells and the crosstalk with residing immune cells as potential pathogenic mechanisms in CRSwNP vs healthy controls by using surgically resected patient samples.
To evaluate the effectiveness, safety and pharmacokinetics of TQH2722 injection in patients with chronic sinusitis with or without nasal polyps.
The goal of this observational study is to learn about clinical and functional outcomes in patients with Chronic rhinosinusitis with nasal polyps and comorbid Severe Eosinophilic Asthma and patients with Chronic rhinosinusitis with nasal polyps only treated with mepolizumab compared to healthy controls. Participants will be asked to give nasal, blood and sputum samples before mepolizumab administration (T0) and at 3 (T3), 6 (T6) and 12 (T12) months after mepolizumab initiation The main aims are to identify airways microbiota modifications and differential gene expression after mepolizumab initiation. Researchers will compare: - Patients with Chronic rhinosinusitis with nasal polyps and comorbid Severe Eosinophilic Asthma - Patients with Chronic rhinosinusitis with nasal polyps only - Healthy subjects The research will address the following questions: 1. What are the prospective clinical and functional outcomes of mepolizumab treatment 2. What is the impact of mepolizumab therapy on the airways microbiota and how this may relate to a potentially reduced need for steroids 3. What are the host differential gene expression patterns and the immune/inflammatory (cytokines/chemokines) profile alterations in airways microenvironment and in systemic circulation in response to therapy 4. What are the associations between host and microbiome variables for building up diagnostic and predictive biomarker classifiers of responsive disease endotypes
This is a multicenter, randomized, double-blind, placebo-controlled Phase II clinical trial to evaluate the efficacy, safety and pharmacokinetics of TQC2731 injection in the treatment of Chronic Sinusitis with Nasal Polyps.
